Tingkat kandungan dalam negeri (TKDN) pada kendaraan taktis Water Cannon (WCV) milik Polri yang rendah mendorong adanya kajian yang mengarah pada peningkatan nilai TKDN. Salah satu penguasaan teknologi dalam pengembangan kendaraan taktis yaitu dengan memilih beberapa komponen tertentu dari kendaraan yang mempunyai daya ungkit tinggi dalam meningkatkan TKDN hingga mencapai 25% atau lebih. Dalam kajian ini komponen yang dipilih yaitu berupa rolling chassis kendaraan. Sesuai dengan spesifikasi kendaraan WCV Tactica milik Polri maka pada kajian ini dipilih WCV 4WD dengan tujuan kendaraan dapat digunakan di medan jalan tanah dan lincah dalam bermanuver. Rolling chassis akan dipilih berdasarkan hasil simulasi performanya berdasarkan beban jalan kendaraan dan traksi roda yang dihasilkan. Simulasi perhitungan dilakukan dengan menggunakan 3 macam merek rolling chassis 4WD yaitu A, B dan C yang tersedia di pasaran lokal Indonesia. Tinjauan utama dalam membandingkan 3 merek rolling chassis ini adalah kemampuan tanjaknya serta kecepatan yang dapat dicapai pada kemampuan tanjak tersebut. Dari hasil kajian disimpulkan bahwa secara keseluruhan desain kendaraan WCV dengan menggunakan rolling chassis merek B lebih layak digunakan. Dengan rolling chassis merek B, kendaraan WCV dapat melalui tanjakan hingga 30Ã‹Å¡ dengan kecepatan maksimal 9 km/jam. Simulasi beban jalan kendaraan dan traksi roda ini dapat digunakan sebagai salah satu metode acuan pemilihan rolling chassis untuk kendaraan WCV.

Fuel atomization plays a main role in determining the performance of dieselengines, where the spray pattern illustrates fuel combustion occurs in thecombustion chamber. From fuel spray test results showed that fuel evaporationcharacteristics of fuel at a certain pressure will effect on engine performance.The higher the injection pressure will reduce the diameter of the fuel sprays(sauter mean diameter), thus speeding up evaporation and mixing processesbetween fuel and air in the combustion chamber with resulted the combustionprocess is more completely. Analysis of fuel atomization simulations performedat injection pressure 150, 180 and 235 bar on the distribution of size,temperature and concentration of air+fuel mixture. Physical chemical parametersresulting are the size and temperature distribution patterns fuel+air mixturesprays. DME is feasible to be used as alternative fuel in diesel engines by adding2?5% lubricant additives. The use of diesel+DME 50/50 mixed fuel provides thelowest fuel consumption by generating power of 3x2,975 watts.Kata kunci: kinerja mesin, solar, DME, simulasi atomisasi, dinamika fluida

Fuel spray injection plays a main role in determining the performance of dieselengines, where the spray pattern illustrates fuel combustion occurs in thecombustion chamber. Characteristics of Sauter Mean Diameter (SMD) spray isdevoted to fuel evaporation, and mixing and combustion quality affected bypressure injection (?P) and the physical chemical properties of the fuel (density,surface tension, viscosity and boiling point). From fuel spray test results showedthat fuel evaporation characteristics of fuel at a certain pressure effect on engineperformance. The higher the injection pressure will reduce the diameter of thefuel sprays after injection (SMD), thus speeding up evaporation and mixingprocesses between fuel and air in the combustion chamber with resulted thecombustion process is more completelyKata kunci: characteristics of fuel spray, diesel fuel, DME.

The electrification of the two-wheel vehicle segment is an important strategy for decarbonising the transportation sector. This study aimed to assess the hybridisation of gasoline motorcycles with battery electric systems as an option for decarbonisation. A gasoline motorcycle that had been converted to a hybrid motorcycle was evaluated in several aspects: energy consumption, greenhouse gas (GHG) emission, and cost of energy. The vehicle was tested under the United Nations economic commission for europe (UNECE) Regulation No.40 and compared to a battery electric motorcycle. The test in internal combustion engine (ICE) mode consumed 233.31 Wh/km of specific energy, emitted 60.69 gCO2/km and cost 1.65 US-cent/km on average. The test in hybrid mode consumed specific energy at 6 % higher and 4 % lower specific energy consumption than ICE, thus not improving the carbon dioxide (CO2) emission and operating cost. In electric battery mode, energy consumption was saved by 83 %, with 35 % lower CO2 and 74 % cost savings. The battery electric motorcycle runs more efficiently with 88 % lower energy consumption, 53.8 % lower CO2 and saved cost by 82 %. If the hybrid controller is improved in future development, it could lower specific energy consumption by 41.7 %, reduce CO2 by 11.2 % and save cost by 35.7 %.
