TNI AL Luncurkan Kapal Siluman Trimaran, Salah satu Kapal Tercanggih Milik Indonesia

TEMPO.CO,  Banyuwangi - TNI Angkatan Laut meluncurkan kapal cepat rudal (KCR) Trimaran di galangan kapal milik PT Lundin Industry Invest di Banyuwangi, Jawa Timur, Jumat, 31 Agustus 2012. PT Lundin Industry Invest adalah perusahaan dalam negeri yang memproduksi kapal-kapal perang sejak 2007.

Peluncuran kapal perang yang diberi nama KRI Krewang ini dilakukan oleh Wakil Asisten Logistik Kepala Staf Angkatan Laut, Laksamana Sayyid Anwar. Kapal ini merupakan pesanan Kementerian Pertahanan untuk memperkuat alat utama sistem pertahanan.

Kapal memiliki panjang 63 meter, kecepatan maksimal 35 knot, bobot 53,1 GT, serta mesin utama 4x marine engines MAN nominal 1.800 PK. Anggaran yang dikeluarkan sebesar Rp 114 miliar dari Anggaran Pendapatan dan Belanja Negara sejak tahun 2009 hingga 2011.

Menurut Wakil Asisten Logistik Kepala Staf Angkatan Laut, Laksamana Sayyid Anwar, KCR Trimaran merupakan kapal siluman yang tidak mudah dideteksi oleh radar lawan.

Kapal ini dibuat dengan teknologi tinggi berbahan serat optik, dipersenjatai peluru kendali dengan jarak tembak hingga 120 kilometer. "Di dunia, kapal seperti ini baru dibuat di Amerika dan Indonesia," kata Sayyid Anwar, Jumat, 31 Agustus 2012.

Kapal ini sendiri baru selesai 90 persen dan dalam proses ditarik dari galangan ke perairan Selat Bali. Pengisian kelengkapan kapal akan dilakukan di Pangkalan TNI AL Banyuwangi.

Pemilik PT Lundin Industry Invest, Jhon Lundin, menyatakan terima kasih atas kepercayaan TNI AL kepada perusahaannya untuk membuat KCR Trimaran ini. "Kapal ini merupakan teknologi baru di Indonesia," kata dia. Bahkan di Asia, kata dia, aplikasi teknologi di kapal ini merupakan yang pertama di Asia.

John bercerita awal mula ide kapal ini berasal dari mantan KSAL Slamet Subiyanto pada 2005 lalu. Saat itu, kata dia, Slamet ingin membuat kapal dengan teknologi tercanggih yang dapat dikerjakan oleh perusahaan dalam negeri.

Peluncuran kapal ini menjadi tontotan warga sekitar. Ratusan warga telah memadati pantai untuk melihat langsung proses penarikan kapal menuju laut.

Advantages and Disadvantages of SEO

Main advantages of SEO.

Research shows that some researchers never click on the sponsored listings and others don't realize that these links are paid for. Approximately 80% of clicks are on natural listings and 20% on paid listings.

A principal benefit of SEO (Search Engine Optimization) is its cost-effectiveness as there is no payment to the search engine for being placed within it. This is very important for the 'search head', high volume low intent searches which are expensive in paid search.

The cost of SEO is relatively fixed, independent of click volume. After initial optimization costs, the cost per click reduces whilst paid search is essentially a variable cost.

Thus there are no media costs although resources are necessary for analysis of key phrases and to complete optimization on the website pages.

Together with paid-search it offers a very targeted audience, visitors referred by SEO will only visit your site if they are seeking specific information on your products or related content.

Disadvantages of SEO.

The major challenge of SEO is that there are billions of pages in the search engine indexes and your position in the SERPS is dependent on a constantly changing algorithm which is not published. Therefore, making your pages visible can require specialist knowledge, constant monitoring and the the ability to respond.

Consequently, the biggest disadvantage of SEO is lack of control. You are at the mercy of the algorithm.

There are other possible issues. Sometimes competitors or affiliates may use less ethical black hat techniques, thereby putting you at a big disadvantage.

Also, in very competitive sectors, it can be hard to get listed in the top few results for competitive phrases and this is when expensive pay-per-click may have to be used.

Because of this lack of visibility it can be hard to make a sound business case for SEO, although it is strikingly obvious of the benefits to most companies of the number one position on Google.

It is quite impossible to predict positions and click volumes from SEO, because future changes to the algorithm are unknown. Likewise you cannot monitor or predict competitor activity.

it is impossible to predict the level of return

So, for a given investment it is impossible to predict the level of return for your dollar, pound or euro or to estimate the likely return compared to paid-search or other, more traditional methods of advertising, where more accurate estimates are possible.

This is not to say that estimates of long-term returns from SEO cannot be made. Always bear in mind that SEO is a long-term strategy and that a long-term cost/benefit analysis is needed.

Jaguar Cars

Jaguar Cars Ltd., better known simply as Jaguar, is a British luxury car manufacturer, headquartered in Whitley, Coventry, England. It is a wholly owned subsidiary of the Indian company Tata Motors Ltd. and is operated as part of the Jaguar Land Rover business.

Jaguar was founded as the Swallow Sidecar Company by Sir William Lyons in 1922, originally making motorcycle sidecars before evolving into passenger cars. The name was changed to Jaguar after World War II due to the unfavourable connotations of the SS initials. Following a merger with the British Motor Corporation in 1968, subsequently subsumed by Leyland, which itself was later nationalised as British Leyland, Jaguar was listed on the London Stock Exchange in 1984, and became a constituent of the FTSE 100 Index until it was acquired by Ford in 1989. Jaguar has, in recent years, manufactured cars for the Prime Minister, the most recent delivery being of a XJ model on 11 May 2010. The company also holds Royal Warrants from HM Queen Elizabeth II and HRH Prince Charles. 

Jaguar cars today are designed in Jaguar/Land Rover's engineering centres at the Whitley plant in Coventry and at Gaydon in Warwickshire, and are manufactured in two of Jaguar/Land Rover's plants, Castle Bromwich assembly plant in Birmingham and Halewood Body & Assembly near Liverpool.

Air Compressors and How They Work

One of the many demands of modern industry, as well as the casual and home power tool user, is what portable power to use. Electricity is efficient and fairly fool-proof, but a source of electricity must be present, a generator, battery, or a cord plugged into an outlet, and the tool itself carries its own electric motor increasing the weight of the tool.

Many shops and individuals are opting for pneumatic power for tools, the tools themselves are lighter and smaller and with the exception of a hose running from a compressor or a pressurized tank, there are no extra items to carry. Air compressors can be used for powering handheld tools, a nail gun or an impact wrench for example, and the compressed air itself can become a tool either to clear away debris and sawdust or to fill an inflatable item.

Air compressors normally use one of three mechanisms for the pump, a piston, a rotary screw, or a spinning vane assembly fan. Piston pumps work similarly to the pistons on an internal combustion engine. As the piston drops, air is drawn into the chamber, and as the piston rises, the air is forced into a tank where the pressure rises with each stroke of the piston. Benefits are price, piston pumps are inexpensive, and reliability, piston pumps have been around for over a hundred years so the technology is well proven.

Rotary screw pumps have two screws that as they rotate, they force air down the shaft and into the tank, as well as compress the air. They have the benefit of being much quieter than piston pumps with less force being applied to the parts, making them last longer; also, rotary screw pumps are more efficient with most of the motion of the pump compressing the air. Spinning vane pumps, also known as centrifugal pumps have a drum with vanes along the walls, and as it spins, the air is drawn in the middle of the drum and forced out the edges. This has the benefit of being very quiet, very efficient and fairly compact for its size, however the amount of compression is limited compared to the other type of pumps.

Most compressors have an attached tank to store the pressurized air and the pump itself only runs when the tank pressure drops below a threshold. Some compressors have attached filters to remove water and oils out of the pressurized air and some have manifolds attached to allow multiple lines to run off of one compressor; many shops will run all the tools off of a single compressor, increasing efficiency.

Using compressed air and air pressure as both a power source and as a tool in itself is becoming more and more common as people search for ways to make their lives easier, and especially for the casual user, compressed air is now an attractive option.

How Does Actuators Work

In actuator valve engineering and design, it is essential for engineers, designers, and manufacturers to fully understand the aspects and processes of using this particular product that would eventually help build effective engineering designs in a safe and efficient manner.

One of the most significant products of the company would be the actuators. To make this technical term simpler, an actuator is a device that transforms or converts energy into motion. Also applied as a force, an actuator usually is a mechanical apparatus that takes energy, normally constructed by liquid, air, or electricity, and converts that into a specific kind of motion. This motion can relate to anything from clamping, blocking, to ejecting. These actuators are normally used in industrial applications or in manufacturing, and may also be used in different objects such as motors, switches, valves, and pumps.

From all the actuators available in the market, the most common type would be the ones that are powered by the air, also known as the air cylinder or the pneumatic cylinder. These air cylinders are air tight, usually made out of metal, which uses the energy of compressed air in order to move a piston. In addition, air cylinders are usually used in assembly processes and in manufacturing. On the other hand, grippers, normally used in robotics, use actuators powered by compressed air in order to work similar to the human touch.

Electricity or hydraulics can be a source of power for actuators. Much like there are air cylinders, there are also electric cylinders and hydraulic cylinders where the cylinder converts electricity or hydraulics into motion, and hydraulic cylinders are often used in several types of automobiles. Most of the actuators available have more than one type of power source. For example, solenoid valves can have the ability to be powered by both electricity and air. Electricity powers the solenoid, and the solenoid, powered by air, actuates the valve. Another option for this would be that the solenoid can be powered by both electricity and the hydraulics.

Whether in a linear motion, a rotary motion, or in an oscillatory motion, actuators can still be used, that is if they can create the motion with only one direction, in a circular motion, or in an opposite direction at normal intervals. Hydraulic and air cylinders can also be classified as single acting, which means that the energy source that justifies the movement in one direction, and that a certain spring is used for the other direction. Having these interchanged, these cylinders can act as double as an acting cylinder, which means that the energy is used in two different directions. Even if actuators are usually explained in terms of mechanical implements, muscles are often given as an example of an actuator. Energy, which is created by eating carbohydrates, is converted by the muscle, which in this case would be the actuator, and transform it into motion, such as playing basketball.

Diesel Pump And Diesel Engine - Let Me Know

Diesel pump or as it is frequently known an injection pump usually is used to fuel a diesel engine, injection pumps can be used to supply fuel to a petrol motor also.

 A diesel pump, in the early engines, would have been powered by the engine using a connection directly to the engines crankshaft. The diesel pump will be timed to inject the diesel into the engine at the exact time throughout the pistons stroke.

 Typically a diesel engine in your standard car, van or lorry will be of the four stroke variety, larger engines used in ships and big machinery will frequently be of the two-stroke type to increase fuel performance. Two-stroke engines you would usually find in a strimmer or model car, of course these use gasoline to operate.

 The main variation with a two-stroke engine is that the primary and ultimate strokes are carried out simultaneously, this has the result of drastically increasing performance at the price of a dirtier exhaust. Another gain is that two-stroke engines can be easily run in reverse, providing a reverse function without the need for complicated gearing mechanisms.

 In the modern engine there are two key sorts of diesel engine, those are the common rail diesel engine and the electronic unit direct injection.

 An electronic unit direct injection assembly combines the injector and diesel pump into a singe part, the diesel pump is, generally, still driven by the engine. An Overhead Camshaft (OHC) drives the diesel pumps and injectors, this is an assembly sat on top of the motor and connected directly to the engines main cam shaft by chain, or more commonly nowadays, a belt.

 The common rail diesel engine consist of a high pressured fuel rail, basically a manifold, supplying separate diesel fuel injectors versus the diesel pump delivering fuel directly to the fuel injectors.

 As declared, above, your recent diesel engine works on a four stroke sequence. You might have heard this termed the Otto cycle after the inventor of the petrol engine, Nikolaus August Otto in 1876. A few years later Rudolf Diesel arrived and, wanting to construct a more fuel efficient motor, came up with the diesel engine in 1892.

 Diesel engines have been a bit sluggish on the up-take, for the regular everyday van, mainly due to their reputation of being noisy and smelly. Clearly this is altering as modern technology makes the diesel engine a more palatable resolution to our current transportation woes.

 The four separate events or strokes in a mainstream four stroke diesel engine are as follows:

 The Intake Stroke: As the piston reaches the top of it's stroke and begins to move downward the air intake valve is opened, this has the result of air being drawn in as the piston moves down.

 The Compression Stroke: As the piston hits the bottom of it's stroke the air intake valve will seal, as the outlet valve is also closed the air contained in the piston chamber is compressed as the piston moves back up the shaft.

 The Combustion Stroke: As the piston hits the peak of the compression stroke gas is injected at the exact moment by the diesel pump and as the piston is fractionally past the top of the upward phase of the compression stroke the diesel to compressed air mixture is ignited. This is where the energy to drive the vehicle is generated, the piston is forced downward driving the engine.

 The Exhaust Stroke: During the pistons last upward stroke the outlet valve is opened and the gases produced from the ignition of the air to fuel combination is expelled out and into the exhaust mechanism. At the end of this stroke the four strokes are complete and the entire process starts again from the beginning.

 One downside to diesel fuel versus petrol is when used in very wintry climates. Diesel will start to freeze at a higher temperature than petrol, this will start off by the diesel becoming thicker and waxy, obviously this will impede the good running of any diesel engine. One trick is to put a small amount of petrol into the diesel fuel combination to help lower the freezing point of the overall mixture.

 This also has the additional benefit of making the overall mixture more combustible, although too high a mixture can damage a diesel engine, even small quantities of petrol in a common rail engine can cause serious problems so seek advice from an experienced mechanic before varying your fuel mixture.

 Another trouble that can be straightforwardly spotted is if your diesel pump is not working, this has the effect of reduced fuel supply or pressure to the fuel mechanism. Key indicators are a failure of the engine to start, a lumpy or loud ignition, or a high pitched whining coming from the motor. You will probably also spot a lack of efficiency when applying the throttle.

 If any of these scenarios occur it would be highly recommended to get your automobile tested by a mechanic who may need to supply you a new diesel pump.

Bmw-- New Electric Concept For 2013

Bmw-- New Electric Concept For 2013

Electric or plug in cars have been the talk of the town ever since reports of global warming and lowering our reliance on fossil fuels has become the norm. However, some would say it is all talk and no walk; or more precisely no new electric cars. Seriously, with all the talk about breaking our addiction to fossil fuels very few car companies have actually produced cars that are sustainable. Thus far, Honda and Toyota seem to be the leading car companies paving the way to the fossil fuel free car. But, even with the beautiful designs that these electric cars, Honda Insight and the Toyota Prius offer, people still have an appetite for a new concept and more choices.

BMW's new electric car, called the i3

BMW is satisfying the consumers appetite for a new sustainable vehicle for the green times we live in, but also for the way people live. BMWs new electric car, called the i3 Concept is being sold as the new urban mobility. The new innovations in the car world are all about pleasing the driver, the passenger, and the environment. And, since this company is known for its high performance engines and superior styling it is about time they got into the race.

The i3 Concept looks like it is from the future. And it kind of is, since it will not be available for purchase until 2013. With its super sleek design and glass panel doors this car is not your old BMW for 1980. Oh no. This car looks like it is ready for the race into the future. Black or tinted all glass doors make this vehicle stand out in front of the rest. However, even though all these new futuristic features have been added, this car still retains all the reliability, safety, and luxury driven standards that have always applied with this car company.

The BMW i3 Concept 

The BMW i3 Concept boasts a generous space for both driver and passenger alike. Of course, this car maker always keeps in mind that a car needs to have sufficient space for long distance travel, and look good while racing down the highway. And, according to its specs it will get 80 to 100 miles on a full charge, with speeds reaching 93 miles an hour.

This vehicle has been designed to be comfortable for long car trips, but also light enough to be efficient and effective as an electric car. Of course this city car is not intended for cross country travel, unless you are stopping every 100 miles or so to plug in again. However, the i3 Concept has really been designed as a city car. Since much of the gas in a regular petrol consuming vehicle is expended in round the town mileage, this car is perfect for moving around the town. Like for those trips to the grocery store, and taking the family to their activities, this car will take you there while expending very little energy along the way.

Audi S3 Is Still The Classiest Fast Hatchback Around.

The Audi S3 Sportback 

is the ideal choice for drivers who want top drawer hot hatch performance in a sophisticated and comfortable package.

It might have lost its most-powerful-hatch crown to the hardcore Ford Focus RS, but its still the classiest fast hatchback around.

The Audi S3 is the enthusiasts edition of its more conservative sibling, the A3 hatchback. First produced by Audi in 1999, the second-generation car launched in 2006 is significantly more muscular than its predecessor, Using the same floor pan as the VW Golf, the Audi S3 offers standard quattro four-wheel drive plus plenty of power and a great chassis to deliver sure-footed performance regardless of road conditions. With a firm ride, the car isnt especially comfortable on badly surfaced roads but for those who want a rapid small hatch that can cope with any road condition, few cars can rise to the occasion like the S3.

The purposeful looks of the Audi S3 hatchback work even better in Sportback form; the extra length and rear doors give it a more grownup appearance. Thanks to a minor facelift the head turning Audi LED daytime-running lights are now fitted, and their piercing light really alters the character of the car. Chrome door mirrors and S3 emblems along with 18-inch alloy wheels separate it further from the rest of the range.

The 2-litre turbocharged engine found in the S3 hatchback and Sportback is an evolution of the motor found in the Volkswagen Golf, Seat Leon Cupra and Audi TTRS. With 261bhp and 258lb/ft of pulling power its significantly more powerful than the Golf GTi, thanks to a larger turbocharger and reworked engine and exhaust components.

The Audi S3 Sportback feels incredibly solid and well built and the engine and Quattro four-wheel drive system are well proven. Audi performs worse than some rivals in the Reliability Index, partly as a result of higher servicing costs than some competitors.

AUDI S3 TYPES

Whereas the first Audi S3 came in three-door hatchback form only, the second-generation car is also offered as a five-door Sportback alongside the three-door edition.

Both cars are mechanically identical however, which means theres a 1984cc four-cylinder up front, turbocharged and intercooled to give 261bhp. This feeds power to all four wheels via a six-speed gearbox, with 18-inch wheels as standard.

These combined with the stiffened and lightened suspension, enables the car to corner far more purposefully than the A3.

There is also a more sporty part-leather interior, topped off with contemporary inserts finished in brushed aluminum or piano black.

DID YOU KNOW?

The S3 has a top speed of 155mph and accelerates from 0-62mph in 5.7 seconds.
The S3 features stiffer suspension than the A3 on which its based, while it also sits 25mm lower to improve roadholding further.
For those who want to feel like a racing driver, the S3 can be ordered with a flat-bottomed steering wheel just like in a Formula One car.
