Menggunakan LCD Projector Dengan Ubuntu

Kebanyakan Ubuntu tidak bisa tampil dengan baik di LCD Projector, salah satunya dalam kasus ini kami menggunakan Laptop Acer Aspire 4520 dengan VGA Nvidia. Kami melakukan ujicoba menggunakan Ubuntu Fiesty/Linux Mint Cassandra. Berikut ini merupakan catatan eksperiment atau langkah-langkahnya:

projector.jpg

Pertama, bukalah file /etc/X11/xorg.conf, dengan perintah berikut

$ sudo gedit /etc/X11/xorg.conf

Kedua, edit beberapa bagian dari isi file tersebut

Pada bagian Section Screen, carilah baris berikut :

Option “TwinView” “0″
Option “metamodes” “1280×800 +0+0; 800×600 +0+0; 640×480 +0+0″

Kemudian ubah menjadi

Option “TwinView” “true”
Option “metamodes” “1280×800 1024×768 800×600 640×480″

tambahkan juga opsi berikut

Option “TwinViewOrientation” “Clone”

Sehingga kurang lebih pada bagian Section Screen akan menjadi seperti ini :

Section “Screen”
Identifier “Screen0″
Device “Videocard0″
Monitor “Monitor0″
DefaultDepth 24
Option “TwinView” “true”
Option “metamodes” “1280×800 1024×768 800×600 640×480″
Option “TwinViewOrientation” “Clone”
Option “NoLogo” “True”
SubSection “Display”
Depth 24
Modes “nvidia-auto-select”
EndSubSection
EndSection

Keterangan :
Pada bagian TwinViewOrientation dapat menjadi opsi menarik untuk membelah layar sehingga tampilan pada LCD Laptop dan pada LCD Projector dapat berbeda.

Ada 4 pilihan opsi TwinViewOrientation, yaitu ; LeftOf, RightOf, Above, dan Below

Sedangkan Clone untuk menyatukan layar di projector dan LCD Laptop.

Yang perlu anda perhatikan adalah jika membelah layar menggunakan TwinView, maka layar utama adalah layar yang tertampil di projector. Sehingga layar notebook anda terlihat kosong. Agar muncul di layar notebook anda, caranya sederhana tinggal anda drag jendela aplikasi yang tidak ingin ditampilkan pada LCD projector.

Berikut ini merupakan penjelasan untuk 4 pilihan opsi TwinViewOrientation:

Orientasi LeftOf, berarti seolah-olah projector ada di sebelah kiri laptop, ketika kursor anda geser melewati sebelah kanan layar projector, maka kursor akan muncul di layar laptop.

Orientasi RightOf, kebalikan dari LeftOf, seolah-olah proyektor ada disebelah kanan laptop. Ketika kursor anda geser melewati sebelah kiri layar projector, maka kursor akan muncul ke layar laptop

Orientasi Below, seolah-olah projector ada di bawah laptop

Orientasi Above, seolah-olah projector diatas laptop.

Untuk mengaktifkan twinview, perlu dilakukan proses restart pada desktop manager anda (tekan tombol Ctrl+Alt+Backspace) .

Jika laptop sudah menyala, kemudian kabel LCD projector baru di tancapkan. Kemudian tekan tombol Ctrl+Alt+Backspace untuk merestart desktop manager.

Setelah itu akan muncul tampilan login, disini anda sudah berada di posisi twinview dan Insya ALLAH. Gambar sudah tertampil di projector.

* cara diatas juga dapat digunakan pada distro linux yang lain

Video projector

A video projector takes a video signal and projects the corresponding image on a projection screen using a lens system. All video projectors use a very bright light to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings. Video projectors are widely used for conference room presentations, classroom training, and home theatre applications.

Overview

A video projector, also known as a Digital Projector, may be built into a cabinet with a rear-projection screen (rear-projection TV, or RPTV) to form a single unified display device, now popular for “home theater” applications.

Common display resolutions for a portable projector include SVGA (800×600 pixels), XGA (1024×768 pixels), 720p (1280×720 pixels), and 1080p (1920×1080 pixels).

The cost of a device is not only determined by its resolution, but also by its light output, acoustic noise output, contrast, and other characteristics. While most modern projectors provide sufficient light for a small screen at night or under controlled lighting such as in a basement with no windows[1], a projector with a higher light output (measured in lumens, abbreviated “lm”) is required for a larger screen or a room with a higher amount of ambient light. A rating of 1500 to 2500 ANSI lumens or lower is suitable for smaller screens with controlled lighting or low ambient light.[1][2] Between 2500 and 4000 lm is suitable for medium-sized screens with some ambient light or dimmed light. Over 4000 lm is appropriate for very large screens in a large room with no lighting control (for example, a conference room). Projected image size is important; because the total amount of light does not change, as size increases, brightness decreases. Image sizes are typically measured in linear terms, diagonally, obscuring the fact that larger images require much more light (proportional to the image area, not just the length of a side). Increasing the diagonal measure of the image by 25% reduces the image brightness by 35%; an increase of 41% reduces brightness by half.

Projection technologies

A Zenith 1200 CRT Projector based home theater. Circa 2006.
  • CRT projector using cathode ray tubes. This typically involves a blue, a green, and a red tube. Minimal maintenance is required (unlike projectors that use expensive lamps which must be periodically replaced after they burn out). This is the oldest system and falling out of favor largely because of the bulky cabinet. However, it does provide the largest screen size for a given cost. This also covers three tube home models, which, while bulky, can be moved
  • LCD projector[3] using LCD light gates. This is the simplest system, making it one of the most common and affordable for home theaters and business use. Its most common problem is a visible “screen door” or pixelation effect, although recent advances have minimized this.
  • DLP projector using Texas Instruments’ DLP technology. This uses one, two, or three microfabricated light valves called digital micromirror devices (DMDs). The single- and double-DMD versions use rotating color wheels in time with the mirror refreshes to modulate color. The most common problem with the single- or two-DMD varieties is a visible “rainbow” which some people perceive when moving their eyes. More recent projectors with higher speed (2x or 4x) and otherwise optimised color wheels have lessened this artifact. Systems with 3 DMDs never have this problem, as they display each primary color simultaneously.
  • LCOS projector using Liquid crystal on silicon.
  • D-ILA JVC’s Direct-drive Image Light Amplifier based on LCOS technology.
  • LED Use an array of Light Emitting Diodes as the light source, negating the need for lamp replacement.

Obsolete technologies

  • Eidophor oil-film projectors
  • Talaria oil-film projectors
  • ILA (Light Image Amplifier) light valves
  • Schmidt-CRT, developed by Kloss Video

DIY video projectors

With a growing DIY-community and an increasing interest in low cost devices, some hobbyists have endeavored to build their own projectors from kits, sourced components, or from scratch. Through the internet, the community is now able to obtain plans to construct DIY-video projectors.[4][5] and there is a growing trend toward building them for domestic requirements and classroom use. The DIY-projectors are now being used both in developed countries and in developing countries in the interest of providing education as well as for entertainment purposes.

Lumens Guide

Below is a fast and easy reference for you to use to help determine how bright a projector you need for business, home theater, and house of worship environments.

Key

* Controlled Lighting: If you plan to use your projector in a room where there are no windows, such as a basement, or if you use your projector primarily at night, any of today's projectors will provide a bright image.

Low ambient light Low ambient light: Little to no light entering room.

Some ambient light Some ambient light: Some additional light in room. Slightly dimmed, window blinds leaking some light.

High ambient light Bright ambient light: Windows open during daylight hours, lights that cannot be dimmed like in an open office settings. Bright enough for audience note taking.


Business - 4:3 Screen

Buying Guide - Projectors

Not sure how to buy a projector or what projector to choose? We've put some information together to help you learn a little bit about projectors and what you need to know when buying one.

What resolution do I need?

Projector resolution is measured in pixels which are tiny squares that make up the image of a picture. The more pixels there are, the sharper the image will appear. Knowing how you will use your projector will help determine the resolution you will need.

SVGA Projector Resolution = 800 X 600 pixels
SVGA is adequate for watching movies, DVDs or TV, however it may show "jaggies" when trying to show computer graphics or PowerPoint slides.

XGA Projector Resolution = 1,024 x 767 pixels
XGA has nearly become the standard for business applications. It can display data, graphics or video without any problem. Not only that, but most notebook computers have a native resolution of XGA, which means the projector will not have to down convert the data.

SXGA Projector Resolution = 1,280 x 1,024 pixels
SXGA is even better resolution. Those who need larger images and/or extra-sharp detail should consider an SXGA resolution projector.

UXGA Projector Resolution = 1,600 x 1200 pixels
UXGA provides very high resolution providing superior detail. UXGA-native resolution projectors are rare, and usually cost quite a bit more.

projector
Home Theater:
SVGA is adequate for home use - watching TV or movies.
projectors
Business or Educational Room:
Will need at least XGA, possibly SXGA resolution to show computer displays.
how to buy
Large Venue: Will probably need SXGA resolution because of the size of the projected image.

How much brightness do I need?

How big of room you will be using your projector in, how much lighting control there is, and how much ambient light is let into the room will help determine the brightness you will need. Because you may have a room that is very small and the lighting is poor, or the room size with the light available do not match up, an adjustment of brightness will need to be made to accommodate for both factors. The size of picture you are projecting and the material of the screen you will use, also play a part in brightness level you'll need. Brightness in projectors is measure by ANSI lumens.

Conditions for low brightness (under 1500 ANSI):
Small rooms, controlled lighting

projectorControlled lighting: No windows, no need for any light. A brightness under 1500 should be adequate.

Conditions for medium brightness (1500 - 3000 ANSI):
Medium size room such as a boardroom or classroom (light allowing for note-taking), somewhat controlled light
projectorsSomewhat controlled lighting: Allows for note taking. We recommend a brightness between 1500 - 3000 ANSI.

Conditions for high brightness (3000+ ANSI):
Large room or venue, no light control

Back to top

how to buyPoor light conditions: Too much outside light - assuming windows cannot be covered. We recommend at least 3000 ANSI.

buying guide
Small room: Under 1500 ANSI should be adequate for a room this size.
buying guide
Medium-sized room: For a room this size, we would recommend a brightness between 1500 - 3000 ANSI lumens.
help
Large room: For a large venue we would recommend having a brightness of 3000 ANSI or higher.

How picture size affects brightness

In general, the larger size image you want to project, the higher brightness you will need to project that image. Generally, when the size of image is doubled, the brightness will need to be quadrupled. Note that picture size is measured diagonally.

Here's an example: A projected image of 100" with 2,000 ANSI brightness, would need to be about 8,000 ANSI lumens for a 200" picture size.

What is the difference between LCD, DLP, and LCoS/D-ILA Technology?

LCD: Liquid Crystal Display
Generally less expensive
Superior color saturation
More light efficient

DLP: Digital Light Processing
Developed by Texas Instruments
Higher contrast which can make images appear brighter than they really are
Sharper images
Smoother gradation of colors and grays

LCoS/D-ILA: Liquid Crystal on Silicon/Direct Drive Image Light Amplifier
LCoS Developed by IBM/D-ILA Developed by JVC
Higher contrast
Improved white balance
Competitors to DLP technology

Keep in mind that no matter which projector technology sounds better, that just looking at brightness specs and contrast ratios can be deceiving. Often times projectors with higher contrast ratios look brighter than they actually are. The best way to choose which chip you want is by seeing live comparisons.

Back to top


Other things to consider

Lamp Life: Replacement lamps are one of the things that are generally not looked at when buying a new projector, but if cost is important to you, then the lamp life and replacement lamp cost should be looked at. Generally, lamp life is between 1,000 to 2,000 hours. Some lamps can have lower or higher lamp life than that, but regardless of the lamp life, the cost of a replacement lamp can be anywhere between $250 - $10,000 for the large venue projectors.

Extra Features: Many features are available for projectors such as network capability, wireless capability, security controls, changeable lenses. Please speak with a professional to find out more.

Warranty: Most projectors come with either a one year, a two year, or a three year warranty. However, these warranties usually do not cover the lamp life. Lamps usually have their own warranty of around 90 hours. If a lamp is bad, it will usually fail within that time frame. Also, be aware that with different manufacturers, there are different warranty programs. For example, some have a program where the manufacturer will replace your projector if it fails within the warranty time - within 24-48 hours. Or, some will provide a temporary projector if your projector is in need of repair and will not be available at the time of a presentation. Nevertheless, don't forget to look at warranty features available. Some manufacturers will sell extended warranties, and a good idea is to buy from a dealer that is authorized to service your brand of projector.

DLP Vs. LCD

The most common questions about front projectors center on the different technologies that they use. Which is better? That depends on what you are looking for. In this section will we compare the technologies as they relate to front projection.

Digital Light Processing™ (DLP™) — DLP™ is a Texas Instruments technology that uses micro mirrors to project an image. There are three distinct types of DLP™ light engines: three chip; single chip for home theater and single chip for business. We will cover the pros and cons for each.

Three chip DLP™ — Pros:

1. Perfect color accuracy.
2. Good contrast; much greater than film theaters.
3. Good shadow detail.
4. Can provide high brightness compared to the limited brightness of single chip versions.
5. Overall image quality deemed as the best of any type of micro display technology.
6. Same technology as projectors installed in digital theaters.
7. Pure digital technology.

Three chip DLP™ — Cons:

1. Very expensive compared to the other technologies. Prices start at around $20k.
2. Lower contrast than single chip versions.
3. Generally larger and always louder than single chip versions.
4. Lamps usually don't last as long.

Single chip DLP™ for home theater — Pros:

1. Fantastic color accuracy.
2. The best contrast ratios and shadow detail.
3. Generally very quiet.
4. Very little space between each pixel creates a very smooth image, even when using lower resolution projectors.
5. Best overall image quality available for under $10k.
6. Very few, if any, dead pixels.
7. Light engine failures are very rare so repairs are less costly than other technologies.
8. Technology doesn't degrade over time. With proper routine maintenance, DLP™ projectors consistently provide just-out-of-the-box performance. (DLP™ is the only technology that makes this claim).
9. Color uniformity is the best of the technologies.

Single chip DLP™ for home theater — Cons:

1. It is more expensive than LCD technologies given comparable projector resolution and brightness.
2. Home theater DLPs only reach a maximum of 1500 lumens of brightness.
3. On some DLP™ projectors, viewers can detect a color breakup effect called the "rainbow" effect. This rarely occurs with home theater DLPs.

Single chip DLP™ for business — Pros:

1. Provides higher brightness than home theater DLPs.
2. Excellent contrast and shadow detail.
3. Generally produces reduced noise levels.
4. Very little space between each pixel creates a very smooth image even when using lower resolution projectors.
5. Very few, if any, dead pixels.
6. Light engine failures are very rare so repairs are less costly than other technologies.
7. Technology doesn't degrade over time. With proper routine maintenance, DLP™ projectors consistently provide just-out-of-the-box performance. (DLP™ is the only technology that makes this claim).
8. Color uniformity is the best of the technologies.
9. Cheaper to purchase - based on resolution and brightness - than true home theater DLPs.

Single chip DLP™ for business — Cons:

1. Color saturation is not as good as LCD or home theater DLP™ machines.
2. Color separation effect, AKA "rainbow effect," can be apparent on these projectors and can be distracting to watch, although most people don't notice the effect.
3. Advanced menu screens for image adjustments are rare in business machines, although some manufacturers do offer them.
4. Most, but not all, business machines won't offer HDCP enabled digital inputs.
5. These machines are only offered in 4:3 aspect ratios.
6. True 720p resolution projectors not offered.

LCD — LCD or liquid crystal displays are the oldest type of micro display technology used in front projection. Since the only real differences between an LCD projector for home theater and one built for business are the resolution and menu options, we won't differentiate between the two here.

Pros:

1. Can be very bright even in home theater applications.
2. True high definition models are the least costly of any technologies with 720p models starting at under $2k.
3. Great color saturation.
4. Home theater models are usually feature-rich.
5. 1000 lumen and lower models will usually have long lasting lamps.

Cons:

1. Dead pixels are common.
2. Contrast ratios are lower than those on DLP™ projectors.
3. Shadow detail and absolute black levels fall short of DLP™ powered projectors.
4. Panel convergence problems (where the three LCD panels don't align properly producing a noticeable color halo around each pixel) are common.
5. LCD panels are organic and lose image quality over time. The less the machine is used each day, the less of a problem this is. Projectors that are used for over eight (8) hours a day can exhibit problems fairly quickly.
6. Color uniformity across the image is lower than that of DLP™ powered projectors.

LCoS — LCoS, or liquid crystal on silicone projectors, came along at about the same time as DLP™ powered projectors and have a much smaller market share than either DLP™ or LCD in the home theater or business machine markets. LCoS technology is also referred to as reflective LCD, while individual manufacturers use their own names. For example, JVC refers to its LCoS light engines as "D-ILA."

Pros:

1. LCoS resolutions tend to start at SXGA enabling native 720p high definition images to be shown.
2. Like LCD, LCoS machines can be very bright.
3. Offers a very smooth, film-like image due to its pixel structure.
4. Great color saturation and accuracy.

Cons:

1. Can be pricey, although based on resolution, the cost is not much more than that of DLP™ home theater projectors.
2. Dead pixels are more visible than with other technologies and happen as often as with LCDs.

LCD Overhead Projector

introLCD Overhead Projector

This is another instructable to build a LCD video projector. I'm using a free LCD that had a bad backlight inverter and a 3M 9550 overhead projector. I'm posting this because my setup differs from the typical video projector because I needed to extend the video cable that runs the horizontal pixels on the monitor since my cable cut across the monitor.

The State of the DIY Projector

The Box:
Many first time builders like to stick with the original Lumenlab rectangular box design. Others like to test their craftsmanship and try to build a Haas Box or Puni5sher's vertical design. Still others like to show their ingenuity and come up with their own design. This section will discuss the most popular box designs currently used.

The Lumenlab Box: This box is probably the most popular box of Lumenlab members. The reason for its popularity is its ease of construction and alignment for first time builders. This box can be summed up as the quick and somewhat dirty way of building a projector. The two big disadvantages of this box are size and appearance. This box is probably the maximum size possible for a Lumenlab projector given the same size monitor. Also, having a big box in your living room is not always going to be the most attractive thing. The most common construction material for this box is MDF or plywood.
Fly CRJ's PLOG

The Haas Box: To overcome the appearance and size of the standard Lumenlab box, Haas man designed the Haas box. First of all, it really isn’t much of a box, but resembles a concave lens lying on its side. The Haas box is almost always made from real wood and stained to match ones furniture in the house. With the nice curved design and stain, the box is much more aesthetically pleasing. This box is harder to construct and has plans which can be used on a CNC machine.
Haas man's PLOG

The Vertical or folded Box: The vertical and folded designs can be box shaped or curved in outside appearance. What differs with these boxes is the use of mirrors. By bending the light path there is less wasted space, sometime significantly reducing the size of the box. The box itself may not be hard to construct but depending on the number of mirrors used (usually one) can make aligning the optics very tedious.
Pun15er's PLOG




The Monitor and Cables
The monitor is most likely going to be the largest single investment in the projector; therefore, you are probably going to want to decide what is best for your application. When choosing a monitor you may want to first check for its compatibility. You can do so at the Compatible monitor list. There are several other things to look at when looking at monitors: contrast ratio, resolution, response time, and inputs.
  • The contrast ratio is the difference between the brightest whites and the darkest black. The contrast ratio is important to some and not so much to others. Some people cannot stand a washed out image to where the blacks appears a dark gray and the white a light gray. Although the contrast ratios stated by different monitor manufacturers can be subjective, a contrast ratio of 500:1 is good, below 300:1 is poor, and above 700:1 is great.
  • Most everyone here knows what the resolution of a monitor is. It is how many pixels a monitor is able to display. The higher the resolution is, the higher the image quality will be. Most monitors have a native resolution associated with them, and any other resolution displayed on it isn’t as clear. If you want your projector to have an image quality of 720p you must have a monitor with 1280 pixels across (1280x1024 or 1280x768)
  • The response time of a monitor is the time it takes for a pixel to go between on and off. For watching movies the response time is not very critical. Movies are typically done at 30 frames per second. Response times become more critical for gamers when playing first person shooters. When objects move quickly across a screen with a slow response time they tend to slightly blur. A monitor with a response time of 12ms is good, 16ms is average, and less than 8ms is great.
  • The most common inputs are VGA and DVI. Some people want composite or component inputs on their monitor so they can connect common home entertainment equipment directly to the projector with out having to use a converter or computer.
15in: 15in monitors are the most commonly used size with the standard lenses. With the introduction of the Pro lenses, and the decrease in price of 17in monitors, more people are building with 17in monitors. 15in monitors usually have a native resolution of 1024x768 which is higher than most entry level commercial projectors. A lot of builders use the Westinghouse brand from Best Buy.

17in: The most inexpensive and readily available monitor to produce 720p is a 17in monitor. There are other smaller monitors that will accomplish this, but they are more expensive and hard to find. Because of its ability to display HD (High Definition) content, some builders are starting to use 17in monitors. Builders use a variety of brands and models of 17in monitors.

<15in: Because of the large size of high resolution LCD monitors, the box for the projector has to be very large. The best way to reduce the size of the box is to use a smaller monitor. The monitor that seems to have the most success is the Hami 8” monitor. It has a resolution of 800x600 and is much smaller than a 15” monitor.

Cables: To connect your projector to your HTPC or TV box you are most likely going to need an extension cable. VGA and DVI are the most common cables leaving the box besides a common power cable. These cables can be found for a very low price at Monoprice. Monoprice’s cables are high quality and sometimes 1/5 the price of competitors.


Antiglare
Almost all LCD monitors on the market, except the Sony X-brite and a few others, have a layer on the front of the display called antiglare. The antiglare diffuses the light that hits the front of the monitor, reducing the glare that bounces back. This helps to see your desktop monitor in well lit environments. Although the antiglare may be beneficial in a desktop environment, it is detrimental in the projector. The antiglare scatters the light causing it to reach the collector fresnel at a different angle than intended. This scattered light does not make it to the triplet, and reduces the brightness, sharpness, and color quality of the image.

Stripping the antiglare: Stripping refers to the method of removing the antiglare from an LCD monitor. This procedure is risky and requires the utmost care and patience. All monitors are different, and one member’s ease of removal may differ from yours even if you own the same monitor. It is important to search the forums regarding you monitor and the ease of stripping its antiglare. The water strip or “rag” method is the most common method for removing the antiglare. There are several threads that outline which monitors have been successful with this method and include a step by step description on how to use the water strip method to remove the antiglare.

The Light
When choosing a bulb there are several factors that are considered including: color temperature, lumen output, arc chamber size, wattage, life expectancy, and ballast.
  • The color temperature of a light describes what color light is being produced. Having a color temperature around 6000k means the bulb produces the closest to white. If a bulb has a color temperature less than this, it produces a yellowish light, and if a bulb has a color temperature greater than this, it produces a bluish light. The closer to white the light is, the more vibrant the colors.
  • Lumen output is very important. This is how much light the bulb produces. Usually the higher the lumen output the better. Most people weight color temperature and lumen output against each other to find which bulb they want.
  • The optics of the projector expects the light to come from a point source which it isn’t. The arc of the bulb usually spans a couple centimeters. Having a bulb with an arc larger than a couple centimeters is impractical because the extra light it may produce is wasted because the optics can’t focus it.
  • As most know, wattage is the power the bulb consumes. The higher the wattage the brighter the bulb is and the more heat it produces. Most people use a 400W metal halide bulb although a few use 250W HQI double ended bulbs.
  • The main advantage Lumenlab projectors have over commercial projectors is bulb life. Most bulbs used in these projectors have a life of 10,000-20,000 hours while most commercial projector bulbs only last 200-2,000 hours. Also, Lumenlab bulbs only cost $30-$50 while commercial bulbs cost $250-$500.
  • Finally, depending on which bulb is used depends on which ballast must be paired with it. Some of the community uses electronic ballasts while others use coil and core ballasts. The electronic ballasts are slightly more expensive, but are much lighter and smaller. The coil and core are cheaper, but weigh around 15 lbs and take up a little more space.
S400DD: The Ushio S400DD 400W bulb is probably the most common light used today by builders. This is only because this is the bulb Lumenlab used to stock. Builders are now starting to use the LL65K T15 bulb. The color temperature of this bulb is 5200k. The lumen output is 33,000 and life expectancy of 15,000 hours. This bulb requires a HPS S51 400W coil and core ballast or electronic ballast

LL65K T15: The LL65K T15 400W bulb is now the bulb sold by Lumenlab. The color temperature of this bulb is 6500k. This bulb has a color rendering of 91 meaning it produces the most accurate colors. The lumen output is 38, 000 and life expectancy of 10,000 hours. This bulb requires a M59 or M135 coil and core ballast or electronic ballast.


The Lenses
The lenses of the Lumenlab projector, also referred to as optics, are responsible for making the projected image show up crisp and clear. Every projector has the two fresnel lenses to direct the light to the triplet. The triplet is responsible for projecting the image. Some builders are now starting to add precondensers lenses in the projectors.

Standard : The standard Lumenlab lens set comes with 2 fresnel lenses and an 80mm triplet. This lens set is recommended for all monitors 15” and below. The standard triplet has been proven to work with 17” monitors but the standard fresnel lenses are too small and must be purchases somewhere else. The triplet lens has a 1:1 ratio, meaning that the projector must be the same distance away from the wall as the projected diagonal.

Pro: The pro lens set comes with two larger fresnel lenses and a 100mm triplet. This lens set is recommended for 17” monitors and above. Although, if this lens set is used with smaller monitors it will increase the throw distance of the projector. This allows the projector to be positioned further back while still projecting the same size image. This triplet allows more light making the projection brighter. This triplet lens has a 1.6:1 ratio allowing the distance from the projection to the projector to be 1.6 times the projected diagonal.

Precondensers: A precondenser lens is a special convex lens that collects more of the light right next to the bulb and bends it towards the fresnel. Many builders are starting to do this because it adds brightness and uniformity to the projected image. Condensers come in many diameters and focal lengths. Mikyd has started the Precondenser Experimentation thread to compile all the information that has been collected so far.


Cooling
Cooling the monitor in the Lumenlab box is very important. Without it the monitor will degrade and eventually expire. To overcome the heat produced fans are installed.

EverCool PCAC: Up until recently these fans were the most recommended, but are now rivaled by 120mm case fans. The EverCool is a cross flow fan which resembles the paddle on a paddleboat. These fans look very good on paper (23dB and 100cfm) but in reality produce a slight whine and have difficultly pulling air with restricted air paths. One of the biggest advantages of the cross flow design is very little light escapes through the fan.

120mm case fans: Slowly, builders are exchanging their EverCool PCACs for a 120mm fans from either Lumenlab or computer part retailers. Although these fan state a higher noise level, builders have stated it is a little quieter than their EverCool. This fan can also move up to 100cfm of air. The only problem with these fans is that they let a lot of light out the box, unless you position it in a way that allows air flow but no light to escape.

80mm case fans :Some builders like to salvage what they have around the house. Most Lumenlab builders have a couple 80mm fans lying around from computers that they have tinkered with. Depending on the fan, these are usually adequate but can sometimes be noisy. As with the 120mm fan, light leaks can be a problem and must be taken into consideration.


Mounting
Because the DIY projector has less of a throw distance than the optimal viewing distance, the projector must be in front of the viewer. To keep the projector out of the way of the viewer it is usually placed on the floor, ceiling or to the side. Of course with all of these methods, some form of keystoning or screen tilt must be applied for the image to appear undistorted and clear.

Ceiling: Most commercial projectors are ceiling mounted, so why not mount your DIY projector from the ceiling. The biggest disadvantage with this route is that these projectors are big and can be quite heavy. If you are going to ceiling mount your projector it is recommended that you know what you are doing, because no one wants a 40lb object falling on an unsuspecting victim. Some builders have made nice rail systems to slide the projector back and forth. This allows them to change the size of the projected image if need be.

Floor: Many that do not want to deal with the hassles of hanging a projector and/or it doesn’t work for their situation. Most builders position their projector on the floor, or not far from it. Some have even gone as far as designing furniture (such as a coffee table) to hide the projector and make it more appealing.

Side: For some, the ceiling and the floor are not an option. These builders place their projector to the side of the screen. Just keep in mind that if you use this option and keystone by pivoting the field fresnel, you must pivot the fresnel vertically.


The Screen
Now you have your projector built and you need something to watch it on. Projection screens can sometimes vastly increase the contrast and gain of your projection, depending on what you are currently projecting on. Most common features of screens are gain, contrast, viewing angle, and hot spotting. Methods are currently being tested to make screens that reflect ambient light but not projected light.

Blackout cloth: Probably the most common screen among Lumenlab builders. Blackout cloth can be bought from almost any fabric store in 54” widths but Lumenlab sell this material in 110” widths. Blackout cloth is the heavy, white, cloth used in combination curtains to block the light from entering your house. The aspect of blocking light makes it better than a standard white fabric. This material is usually stretched over a wooden frame, keeping wrinkles from distorting your image. Some advantages of this screen are that it is cheap, easily acquired, wide viewing angle, and no hot spotting.

White Paint: Some builders have a nice bare wall they would like to project their image on instead of building or buying a screen. There have been many debates if a white wall or blackout cloth make a better screen, and the outcome is that they are about the same. The paint used is usually a flat white, but some have used silver to increase gain brightness and make blacks come out better. Flat white paint has no hot spotting while the silver usually does. Some have stated that the disadvantage of using a painted wall is that it brings out the imperfections in the wall in the projected image.


UV, IR, Reflectors and Heat Shields
So you have figured out what light kit you are going to use. Now you need to make sure that light gets to the monitor, but the heat doesn't.

Heat Shields These are an important component of every projector. Heat shields are installed between the bulb and the first fresnel lens to help block heat from getting to the fresnel and monitor.
  • XL10: This is a UV blocking lexan. This is probably the most common method for blocking UV light from the bulb and providing a heat shield for the rear fresnel and monitor. Most people get this from their local Home Depot and it usually costs around $10. The main advantages of XL10 are that is cheap, blocks UV, and can easily be cut to the needed dimensions at your own home. Just make sure when framing the lexan to leave a little expansion room for when the lexan is heated.
  • Tempered Glass: Other members use tempered glass as their heat shield. Since the tempered glass doesn’t block UV, a filter must be purchased from Lumenlab to block UV. Another hassle is you have to go to the glass store and have them cut it to size for you, so you better know the exact dimensions of your box. The advantages of tempered glass are that it doesn’t bow when heated, and it blocks heat a little better.
Reflectors: The reflector is used to get more usable light to triplet to brighten the projection. The most common method is by using a spherical reflector so the light is reflected straight back through the arc of the bulb. Two of the most common reflectors are:
  • IKEA Soaré napkin holder: This reflector works with all the bulbs stated above and most all other bulbs. If you do not have an IKEA store near by we have members who will help you get a hold of one.
  • Pro Reflector: This reflector is designed by Lumenlab to work well with tubular style bulbs. It is extremely reflective and coated with an IR pass filter to allow the heat to pass through the reflector instead of being bounced back towards the fresnel and monitor. Note: Be careful when handling this reflector as to not rub any of the IR filter off.
Hot Mirrors: These are special mirrors that reflect IR light and transmit visible light. Most of the heat that reaches the monitor is caused by the IR light being absorbed into the monitor itself. A few builders use them in their projectors. These tend to be pretty expensive but when used, you may be able to get away with not having any active cooling in your box at all.


TV Boxes and HTPCs
Now that your projector is built you might need something to plug it into. Three of the most common things used to drive the projector are an HTPC (Home Theater Personal Computer), TV box, or transcoders.

TV Boxes: TV Boxes are usually a small box that have various inputs and outputs including composite, component, VGA, coaxial and much more. These are mostly used if you want to hook up most of your existing AV equipment to the projector. Although this method works and is an inexpensive alternative, by not using a HTPC you will be sacrificing image quality. The most common TV Box is the Viewsonic N6.

HTPCs: HTPCs are used by most Lumenlab members to drive their projector. By using a computer, you open up thousands of possibilities to tweak every last aspect of your projected image. Based upon your hardware and software you use you can drastically improve your image quality compared to using a TV box. If you do not already own a computer that you can run your projector off of than this method could be more expensive. Some common programs to look into are: WinDVD6, Zoomplayer, FDDShow, Dscaler, and Powerstrip. There are many more out their but these are some of the most common and essential programs.

Transcoders: Transcoders are a toned down version of a TV box. Transcoders allow you to convert component to VGA for your monitor with very little loss in image quality. One of the most common transcoders is the VDigi VD-Z3.

Tips
Add a list of helpful tips that we would have all loved to know before building.
  • Monitor Stripping:
    Typically there are row drivers and column drivers that burnout and cause a given row or column not to be addressed - simply stated, it is not connected electrically any more to the display. If a block of lines goes out, the entire driver has probably been damaged. One possibility is that the TAB driver has disconnected from the surface. The TAB driver is connected to the transparent traces on the glass using an anisotropic conductive film (ACF). Sometimes that film will be damaged and a particular connection between a row and a column in the driver can be destroyed. If you have a row or a column driver damaged, the driver needs to be replaced. In a CG silicon display where the driver is on the glass there is no repair. Chip-on-film drivers can be replaced in their entirety.

    The real issue is what causes these failures. They are typically caused by electrostatic discharge. You should make sure that your manufacturing area is properly handling displays especially before they are connected to a ground. Make sure that personnel handling displays are working with wrist straps and are working on a conductive floor. An ionized air flow environment with a slightly elevated humidity is recommended for handling displays that are not yet grounded in a system. When removing protective plastic film, remove in the direction away from the drivers and should remove it at a relatively slow rate to eliminate the build up of a strong static charge on the display. When these precautions are taken, you should see minimal or no damage to row or column drivers and most line-out problems will be eliminated.

Jakarta (also DKI Jakarta), is the capital and largest city of Indonesia. It also has a greater population than any other city in Southeast Asia. It was formerly known as Sunda Kelapa (397-1527), Jayakarta (1527-1619), Batavia (1619-1942), and Djakarta (1942-1972). Located on the northwest coast of Java, it has an area of 661.52 square kilometres (255.41 sq mi) and a population of 8,489,910[1]. Jakarta is the country's economic, culture and political center. Jakarta currently is the twelfth largest city in the world. Its metropolitan area, Jabodetabek, contains more than 23 million people, and is part of an even larger Jakarta-Bandung megalopolis.[citation needed]

Jakarta is served by the Soekarno-Hatta International Airport and Tanjung Priok harbour. Since 2004, Jakarta, while under the governance of Sutiyoso, has built a new bus system known as "TransJakarta" or "Busway", and is now planning to expand the number of routes. The city had hoped to establish its newest transportation system, the Jakarta Monorail, in 2007, but the project was abandoned by the developer, PT Jakarta Monorail, in March 2008. Jakarta is the location of the Jakarta Stock Exchange, the Bank of Indonesia, and the National Monument, or Tugu Monas.

Geography


Jakarta skyline and Mount Gede

Jakarta is located on the northwestern coast of Java Island, at the mouth of the Ciliwung River on Jakarta Bay, which is an inlet of the Java Sea. The northern part of Jakarta is constituted on a plain land, approximately eight meters above the sea level. This contributes to the frequent flooding. The southern parts of the city are hilly. There are about 13 rivers flowing through Jakarta, mostly flowing from the hilly southern parts of the city northwards towards the Java Sea. The most important river is the Ciliwung river, which divides the city into the western and eastern principality. The city border is the province of West Java on its east side and the province of Banten on its west side.

The thousand islands, which is a part of the administrative region of Jakarta, is located in the Jakarta Bay. These 105 islands are located 45 kilometres (28 mi) on the north part of the city.

Climate

Jakarta has a hot and humid equatorial/tropical climate (Af) according to the Köppen climate classification system. Located in the western-part of Indonesia, Jakarta's wet season rainfall peak is January with average monthly rainfall of 350 millimetres (14 in), and its dry season low point is August with a monthly average of 60 millimetres (2.4 in).[2] The city is humid throughout the year with daily temperature range of 25° to 38°C (77°-100°F).[3]

History

For more details on this topic, see History of Jakarta.

The former Stadhuis of Batavia, the seat of Governor General of VOC. The building now serves as Jakarta Historical Museum, Jakarta Old Town area.

Dutch Batavia in the 17th Century, built in what is now North Jakarta

The old name of Jakarta was Sunda Kelapa. The earliest record mentioning this area as a capital city can be traced to the Indianized kingdom of Tarumanagara as early as the fourth century. In AD 39, King Purnawarman established Sunda Pura as a new capital city for the kingdom, located at the northern coast of Java.[4] Purnawarman left seven memorial stones with inscriptions bearing his name spread across the area, including the present-day Banten and West Java provinces. The Tugu Inscription is considered the oldest of all of them.[5]

After the power of Tarumanagara declined, all of its many territories, including Sunda Pura, became part of the Kingdom of Sunda. The harbour area were renamed Sunda Kelapa as written in a Hindu monk's lontar manuscripts, which are now located at the Bodleian Library of Oxford University in England, and travel records by Prince Bujangga Manik.[6] By the 14th century, Sunda Kelapa became a major trading port for the kingdom. The first European fleet, four Portuguese ships from Malacca, arrived in 1513 when the Portuguese were looking for a route for spices, especially black pepper.[7]

The Kingdom of Sunda made a peace agreement with Portugal by allowing the Portuguese to build a port in 1522 in order to defend against the rising power of the Sultanate of Demak from central Java.[8] In 1527, Fatahillah, a Sumatran Malay warrior from Demak attacked Kingdom of Sunda and succeeded in conquering the harbour on June 22, 1527, after which Sunda Kelapa was renamed Jayakarta.[8]


The Castle of Batavia, seen from West Kali Besar by Andries Beeckman circa 1656-58

Through the relationship with Prince Jayawikarta from the Sultanate of Banten, Dutch ships arrived in Jayakarta in 1596. In 1602, the British East India Company's first voyage, commanded by Sir James Lancaster, arrived in Aceh and sailed on to Banten where they were allowed to build a trading post. This site became the center of British trade in Indonesia until 1682.[9]

Apparently, Jayawikarta also made a trading connection with the English merchants, rivals of the Dutch, by allowing them to build houses directly across from the Dutch buildings in 1615.[10] When relations between Prince Jayawikarta and the Dutch later deteriorated, Jayawikarta's soldiers attacked the Dutch fortress. But even with the help of fifteen British ships, Prince Jayakarta's army wasn't able to defeat the Dutch, in part owing to the timely arrival of Jan Pieterszoon Coen (J.P. Coen). The Dutch burned the English fort, and forced the English retreat on their ships. With this victory, Dutch power in the area was consolidated. In 1619 they renamed the city "Batavia."


Batavia c.1870

Within Batavia's walls, wealthy Dutch built tall houses and pestilential canals. Commercial opportunities attracted Indonesian and especially Chinese immigrants, the increasing numbers creating burdens on the city. Tensions grew as the colonial government tried to restrict Chinese migration through deportations. On 9 October 1740, 5,000 Chinese were massacred and the following year, Chinese inhabitants were moved to Glodok outside the city walls.[11] The city began to move further south as epidemics in 1835 and 1870 encouraged more people to move far south of the port. The Koningsplein, now Merdeka Square, was completed in 1818, and Kebayoran Baru was the last Dutch-built residential area.[11]

The city was renamed "Jakarta" by the Japanese during their World War II occupation of Indonesia. Following World War II, Indonesian Republicans withdrew from allied-occupied Jakarta during their fight for Indonesian independence and established their capital in Yogyakarta. In 1950, once independence was secured, Jakarta was once again made the national capital.[11] Indonesia's founding president, Sukarno, envisaged Jakarta as a great international city. He instigated large government-funded projects undertaken with openly nationalistic and modernist architecture.[12][13] Projects in Jakarta included a clover-leaf highway, a major boulevard (Jalan Sudirman), monuments such as The National Monument, major hotels, and a new parliament building.

In 1966, Jakarta was declared a "special capital city district" (daerah khusus ibukota), thus gaining a status approximately equivalent to that of a state or province.[14] Lieutenant General Ali Sadikin served as Governor from this time to 1977; he rehabilitated roads and bridges, encouraged the arts, built several hospitals, and a large number of new schools. He also cleared out slum dwellers for new development projects—some for the benefit of the Suharto family[15][16]—and tried to eliminate rickshaws and ban street vendors. He began control of migration to the city in order to stem the overcrowding and poverty.[17] Land redistribution, structural adjustment,[citation needed] and foreign investment contributed to a real estate boom which changed the face of the city.[18] The boom ended with the 1997/98 East Asian Economic crisis putting Jakarta at the center of violence, protest, and political maneuvering. Long-time president, Suharto, began to lose his grip on power. Tensions reached a peak in the Jakarta riots of May 1998, when four students were shot dead at Trisakti University by security forces; four days of riots and violence ensued resulting in the loss of an estimated 1,200 lives and 6,000 buildings damaged or destroyed.[19] Suharto resigned as president, and Jakarta has remained the focal point of democratic change in Indonesia.[20] A number of Jemaah Islamiah-connected bombings have occurred in the city since 2000.[11]

Administration

Officially, Jakarta is not a city, but rather a province with special status as the capital of Indonesia. It is administered much like any other Indonesian province. For example: Jakarta has a governor (instead of a mayor), and is divided into several sub-regions with their own administrative systems. Jakarta, as a province, is divided into five cities (kota), formerly municipalities, each headed by a mayor, and one regency (kabupaten) headed by a regent. In August 2007, Jakarta held its first ever election to pick a governor; the election was won by Fauzi Bowo. The city's governors have previously been appointed by local parliament. The poll is part of a country-wide decentralization drive, allowing for direct local elections in several areas.[21]

Culture

As the economic and political capital of Indonesia, Jakarta attracts many foreign as well as domestic immigrants. As a result, Jakarta has a decidedly cosmopolitan flavor and a diverse culture. Many of the immigrants are from the other parts of the island of Java, bringing along a mixture of dialects of the Javanese and Sundanese languages, as well as their traditional foods and customs.

Jakarta is sometimes called "The Big Durian" by foreigners resident in the city. The durian is a tropical fruit with a distinctive odor and acquired taste. A bustling urban metropolis, Jakarta is known for its overcrowding, traffic congestion, and income disparity.

The Betawi (Orang Betawi, or "people of Batavia") is a term used to describe the descendants of the people living around Batavia and recognized as a tribe from around the 18th-19th century. The Betawi people are mostly descended from various Southeast Asian ethnic groups brought or attracted to Batavia to meet labor needs, and include people from various parts of Indonesia.[22] The language and culture of these immigrants are distinct from those of the Sundanese or Javanese. The language is more based on East Malay dialect and enriched by loan words from Javanese, Chinese, and Arab. Nowadays, the Jakarta-dialects used by people in Jakarta is loosely based on Betawi Language.

There has also been a significant Chinese community in Jakarta for many centuries. Officially, they make up 6% of the Jakarta population, though this number may be under-reported.[23]


One of the many Sukarno era statues in the city

Jakarta has several performance centers, such as the Senayan center. Traditional music is often found at high-class hotels, including wayang and gamelan performances. As the nation's largest city and capital, Jakarta has lured much national and regional talent who hope to find a greater audience and more opportunities for success.

Ironically, the Betawi arts are rarely found in Jakarta due to their infamous low-profile and most of them had moved to the border of Jakarta, ridden by the wave of immigrant. It is easier to find Java or Minang based wedding ceremonial instead of Betawi wedding in Jakarta. It is easier to find Javanese Gamelan instead of Gambang Kromong (mixture between Betawi and Chinese music) or Tanjidor (mixture between Betawi and Portuguese music) or Marawis (mixture between Betawi and Yaman music). However, some festivals such as Jalan Jaksa Festival or Kemang Festival tried to preserve the Betawi art by inviting the artist to do some performances.[24]

The concentration of wealth and political influence in the city means that it has much more noticeable foreign influence on its landscape and culture, an effect illustrated by the presence in the city of many major international fast-food chains, for example.

Transportation


Jalan Thamrin, a main road in Central Jakarta

One of the most populous cities in the world, Jakarta is strained by transportation problems."[25] In Indonesia most communal transport is provided by bemos, which are privately run minibuses.

Road transport


Jakarta traffic

Despite the presence of many wide roads, Jakarta suffers from congestion due to heavy traffic, especially in the central business district. To reduce traffic jams, some major roads in Jakarta have a 'three in one' rule during rush hours, first introduced in 1992, prohibiting fewer than three passengers per car on certain roads.

Jakarta's roads are notorious for undisciplined driver behavior; transportation laws are broken with impunity and police bribery is commonplace. The painted lines on the road are regarded as mere suggestions as vehicles often travel four or five abreast on a typical two-lane road. It is not uncommon to encounter a vehicle traveling the wrong direction in a given traffic flow. Furthermore, in recent years the number of motorcycles on the streets has been growing almost exponentially. The vast sea of small, 100-200cc motorcycles, many of which have 2-stroke motors, create much of the traffic, noise and air pollution that plague Jakarta.


Motorised bajaj

Auto rickshaws, called bajaj (pronounced badge-eye), provide local transportation in the back streets of some parts of the city. From the early 1940s to 1991 they were a common form of local transportation in the city. In 1966, an estimated 160,000 rickshaws were operating in the city; as much as fifteen percent of Jakarta's total workforce was engaged in rickshaw driving. In 1971, rickshaws were banned from major roads, and shortly thereafter the government attempted a total ban, which substantially reduced their numbers but did not eliminate them. An especially aggressive campaign to eliminate them finally succeeded in 1990 and 1991, but during the economic crisis of 1998, some returned amid less effective government attempts to control them.[26]

To reduce traffic congestion, a new TransJakarta bus system was introduced.

The TransJakarta service operates on a special bus-line called the busway. The busway network is optimized for busy city routes and is a relatively effective alternative for travel in Jakarta. Construction of the 2nd and 3rd corridor routes of the busway was completed in 2006, serving the route from Pulo Gadung to Kalideres. The busway serving the route from Blok M to Jakarta Kota has been operational since January 2004.

An outer ring road is now being constructed and is partly operational from Cilincing-Cakung-Pasar Rebo-Pondok Pinang-Daan Mogot-Cengkareng. A toll road connects Jakarta to Soekarno-Hatta International Airport in the north of Jakarta. Also connected via toll road is the port of Merak and Tangerang to the west and Bekasi, Cibitung and Karawang, Purwakarta and Bandung to the east.

Rail and Waterway

While numerous railways serve Jakarta, they are inadequate to the residents' transport needs. During peak hours, the number of passengers greatly exceeds the system's capacity. The railroads connect Jakarta to its neighboring regions: Depok and Bogor to the south, Tangerang and Serpong to the west, and Bekasi, Karawang, and Cikampek to the east. The major rail stations are Gambir, Jatinegara, Pasar Senen, Manggarai, Tanah Abang, and Jakarta Kota.


Jakarta Railway transportation system

Two lines of the Jakarta Monorail are under construction: the green line serving Semanggi-Casablanca Road-Kuningan-Semanggi and the blue line serving Kampung Melayu-Casablanca Road-Tanah Abang-Roxy. In addition, there are plans for a two-line subway (MRT) system, with a north-south line between Kota and Lebak Bulus, with connections to both monorail lines; and an east-west line, which will connect with the north-south line at the Sawah Besar station. The current project, which began in 2005, has been delayed due to a lack of funds, and the project has been abandoned by the developer PT Jakarta Monorail in March 2008. The government is now looking for new investors.

On 6 June 2007, the city administration started to introduce the Waterway, a new river boat service along the Ciliwung river.[25] The move aims to reduce the traffic snarls in Jakarta.[27]

On 30 November 2007, KRL(Commuter Train) Ciliwung Blue Line began operation.[28] It serves Jakarta's circle line, which was used in the 80s. The fare price is Rp5000,00. It serves Manggarai, Mampang, Karet, Jend. Sudirman Road, Duri, Angke, Kampung Bandan, Rajawali, Kemayoran, Pasar Senen, Gang Sentiong, Kramat, Pondok Jati, and Jatinegara. The train can carry 400 passengers.[29]

Air

Soekarno-Hatta International Airport (CGK) is the primary airport for Jakarta and Indonesia alike. It is used by both private and commercial carriers connecting Jakarta with other Indonesian cities. It is also Indonesia's main international gateway. The airport is divided into three separate terminals. Terminal 1 serves all domestic airliners except Garuda Indonesia. Terminal 2 serves all foreign carriers and Garuda Indonesia (both domestic and international routes). Terminal 3 serves for hajj pilgrimage flights and for transnational migrant laborers.[30] A second airport, Halim Perdanakusuma International Airport(HLP) serves mostly private and presidential flights.

Education

Jakarta is the home of many universities, the oldest of which are state-run University of Indonesia(UI)[31] and the privately-owned Universitas Nasional (UNAS)[32]. There are also many other private universities in Jakarta, such as Universitas Trisakti [33] and Universitas Tarumanagara, which are two of the few largest private universities in Jakarta. As the largest city and the capital, Jakarta houses a large number of students from various parts of Indonesia, many of whom reside in dormitories or home-stay residences. Similar to other large cities in developing Asian countries, there are many professional schools. For basic education, there are a variety of primary and secondary schools, tagged with public (national), private (national and bi-lingual national plus) and international schools. Two of the major international schools located in Jakarta are the Jakarta International School and the Gandhi Memorial International School. JIS is an IASAS school.

Sports

Since Soekarno's era, Jakarta has often been chosen as the venue for international sport events, such as being the host of Asian Games in 1962, host of Asian Cup 2007 and several times hosting the regional-scale Sea Games. Jakarta is also home of several professional soccer clubs. The most popular of them is Persija, which regularly plays its matches in the Lebak Bulus Stadium. Another premiere division team is Persitara. The champions of Galatama competition, Warna Agung and Jayakarta soccer club, also homebase in Jakarta. The biggest stadium in Jakarta is the Bung Karno Stadium with a capacity of 100,000 seats[34]. For basketball, the Kelapa Gading Sport Mall in Kelapa Gading, North Jakarta, with a capacity of 7,000 seats, is the home arena of the Indonesian national basketball team. Many international basketball matches are played in this stadium. The Senayan sports complex comprises several sport venues, which include the Bung Karno soccer stadium, Madya Stadium, Istora Senayan, a shooting range, a tennis court and a golf driving range. The Senayan complex was built in 1959 to accommodate the Asian Games in 1962. In 2011, Jakarta, together with Bandung, will once again host the Southeast Asian Games. Preparations to host the event have started since the conclusion of the 2007 Thailand Southeast Asian Games. The Indonesian Polo Association, as the governing body of polo in Indonesia, have stated its commitment to host the SEA Games polo tournament in Indonesia after polo is confirmed to be absent in the 2009 Laos Southeast Asian Games. The Indonesian Polo Team were placed last in the 2007 Southeast Asian Games.

Population in excess of infrastructure

Like many big cities in developing countries, Jakarta suffers from major urbanization problems. The population has risen sharply from 1.2 million in 1960 to 8.8 million in 2004, counting only its legal residents. The population of greater Jakarta is estimated at 23 million, making it the fourth largest urban area in the world. The rapid population growth has outgrown the government's ability to provide basic needs for its residents. As the third biggest economy in Indonesia, Jakarta has attracted a large number of visitors. The population during weekdays is almost double that of weekends, due to the influx of residents residing in other areas of Jabotabek. Because of government's inability to provide adequate transportation for its large population, Jakarta also suffers from severe traffic jams that occur almost every day. Air pollution and waste management are also severe problems. By 2025 the population of Jakarta may reach 24.9 million, not counting millions more in surrounding areas.[35]

Sanitation

Surveys show that "less than a quarter of the population is fully served by improved water sources. The rest rely on a variety of sources, including rivers, lakes and private water vendors. Some 7.2 million people are [without clean water]."[36]

Flooding

During the wet season, Jakarta suffers from flooding due to clogged sewage pipes and waterways, deforestation near rapidly urbanizing Bogor and Depok, and the fact that 40% of it is below sea level[citation needed]. Terrible floods occurred in 1996[37][38] when 5,000 hectares flooded [39] and 2007.[40] Losses from infrastructure damage and state revenue were at least 5.2 trillion rupiah (572 million US dollars) and at least 85 people were killed [41] and about 350,000 people forced from their homes.[42]. Approximately 70% to 75% of Jakarta's total area was flooded and water up to 4 meters deep in parts of city.[43] [44] [45]

The informal sector

In September 2007, a new law was brought into effect which attempted to regulate aspects of public order. It forbids the giving of money to beggars, buskers and hawkers, bans squatter settlements on river banks and highways, and prohibits spitting and smoking on public transportation. Unauthorized people cleaning car windscreens and managing traffic at busy intersections will also be penalized. Critics of the new legislation claim that such laws will be difficult to enforce and ignore the desperate poverty of many of the capital's inhabitants.
