Makalah ini membahas tentang desain sistem kendali motor DC brushless menggunakan microcontroller ATMega 16 untuk diimplementasikan pada independent 4-Wheel drives pada platform Mobil Robot LIPI versi 2 (REV-11). Sistem kendali yang dibuat terdiri dari 2 bagian yaitu modul kendali motor DC brushless dan kendali supervisor yang berfungsi untuk mengoordinasi perintah ke modul-modul kendali motor. Untuk mengendalikan platform REV-11, kendali supervisory mengirimkan data referensi berupa kecepatan dan arah pada modul kendali motor sebagai referensi untuk mengendalikan kecepatan dan arah dari masing-masing aktuator pada platform REV-11. Dari hasil pengujian disimpulkan bahwa sistem kendali yang didesain sudah mampu berfungsi dengan baik untuk mengkoordinasi dan mengendalikan kecepatan dan arah gerak motor aktuator platform REV-11.

The rising number of vehicles over the years has driven the increase of air pollution and fuel consumption. One of the solutions to overcome this problem is using hybrid electric car because it is environmentally friendly and efficient in fuel consumption. LIPI has conducted electric car research since 1997, but there were so many problems in its development that electric car can not be developed into a national industry scale. Therefore, it is important to conduct a study that maps the problems and finds the solutions to prevent the same failure of electric car commercialization process from happening to hybrid electric car . This study was done by collecting and analyzing the primary and secondary data through interviews, discussing electric hybrid car with stakeholders, and examining earlier study results and regulations. Based on this study, several policies to support sustainability research of hybrid electric car were proposed. Some recommendations were the making of national roadmap and regulation for the usage of hybrid electric car on the road. For policy makers at LIPI, a research focus, research coordination, and pre-commercialization program were recommended.Key words: national policy, hybrid electric cars, research, air pollution, national road map.

The  number  of  vehicle  that  use  oil  (BBM)  is  increasing  every  year  in  Indonesia  while  national  oil  reserve become smaller, so that the oil should be imported. The impact of using oil are increasing subsidy and air pollution.  Thus, it is now becoming important to replace oil with another environmentally friendly energy, one of them is gas (BBG). Based on the number of vehicle and infrastructure in gas pipeline, part of northern West Java potentially can  be  chosen  for  the  implementation  of  conversion  program  to  gas  (BBG).  The number  of  vehicle  in  potential regions  such  as  Depok,  Cibinong,  Bogor,  Bekasi,  Cikarang,  Karawang,  Purwakarta,  Cirebon,  and  Bandung  are around 875,505 units. From these data, we simulated the potential profit to be gained each year by converting 10% for the first year and increasing it to 5% for every year. By investing 3.16 trillion for conversion, 14.9 trillion can be achieved in  the  form  of  fuel  subsidy  savings.  In  addition,  emission  reduction  converted  to  a  CDM  (clean development  mechanism)  can  become  local  revenues.  Total CDM generated during 5 years predicted is of U.S $ 772,385. From this study, it can be concluded that converting oil (BBM) to gas (BBG) is highly beneficial.
