A mini car, lightweight, and highly efficient manufacturing is being perfected by a team from the University of Gadjah Mada (UGM) in cooperation with Shell. The car was tested yesterday in the campus area.

Lutfi Rakhmawati, Jogja
------------------------------ --------The name of the car was taken from the puppet figures: Semar. The shape is similar to grains of water, slightly oval and slightly pointed ends. Car length 2.7 meters. Height less than 1 meter, exactly 0.88 meters, and width is also less than 1 meter (0.88 feet).
Approximately at 12.00 yesterday (17 / 3) the car is on display to the public at the University Club (UC) GMU. According to plan, Semar will race at the event included Shell Eco Marathon (SEM) Asia 2010 at the Sepang Circuit, Malaysia, July. In addition to GMU, universities such as ITB, ITS, and the UI follow the prestigious event. There are two types of diperlombaan. Namely, the category of car and car futuristic urban or urban car. GMU will follow the race categories of futuristic.
Semar is designed very light. When on display yesterday, the weight of the car that made students of Mechanical Engineering and Industrial Engineering Faculty (FT) UGM was only 25 pounds. "This car was designed with three considerations," said Jayan Sentanuhady, supervising Shell Eco Marathon Racing Team (Semart) GMU, told reporters. The third consideration is the minimum weight, efficient engine, and a small friction coefficient.
"The combination of these three things have an effect on fuel consumption. The smaller the coefficient of movement, the minimum energy required, and the more fuel efficient is needed," he explained.
Jayan added, in the event yesterday Semar weights about 25 pounds. The weight of the car is light because the body is made of composite fiber materials and airfoil. In addition, the frame structure using a combination plate and aluminum. The weight of it will continue down until later when the race can reach 20 pounds only. "Weight is very influential on speed. The first time we've made, weighs 35 kilograms," he said.
With the heavy weight that, when simulated in the laboratory of Mechanical Engineering and Industrial FT UGM, the car traveled 600 kilometers with 1 liter of fuel. "Therefore, the weight will continue to be lowered. Our target, one liter can be used to cover 1,000 kilometers," he said.
Semar design is not final. Until now, the level of new fuel keiritan on stage estimation after simulated in the laboratory. If nothing gets in the way, Semar be tested at the road end of May. Yesterday the car was only tested on the boulevard around the campus of GMU. The car uses unleaded fuel 95. Namely, a type of pertamax plus the price of Rp 7,000 per liter range.
According Jayan, current world record held by France teririt car. "One of the universities in France managed to create a car that uses 1 liter of fuel have traveled 3700 miles," he said. He said, Semar will continue to be improved. "For speed, we peg the average ratatanya 30? 35 km / h," he added. "We want the future can cover the distance Semar Anyer? Panarukan only with one liter of fuel," he continued. Distance Anyer-Panarukan estimated 1,000 kilometers.
Alva Edy Tontowi, Semar designer, said that by design are made now, one passenger car was uncomfortable. "Convenience is not the main priority of this car," he said. When on display yesterday, the driver who will get into the car need help some people. The driving position must be supine. "Drivers are also still need guidance from the co-driver. But, since the beginning of creation, this car is designed for speed and efficiency. Form like that, though uncomfortable, producing a small friction coefficient. Only explains Alva.
Darwin Silalahi, country chairman and president director of PT Shell Indonesia, which yesterday saw the launch of Semar, said that the car was one of nine teams from four universities who will compete in the SEM. "We hope that the nine teams that were sent there to show off. It is at once became one container for the younger generation who want to develop innovations in the field of transportation,"
