Abstract


Cadangan minyak bumi Indonesia terus menurun sedangkan jumlah kendaraan dan kebutuhan bahan bakar di Indonesia semakin meningkat. Peningkatan jumlah kendaraan, yang mana performa pembakarannya yang kurang   sempurna dapat mengakibatkan banyaknya polusi udara. Penelitian ini bertujuan untuk meningkatkan kinerja motor bakar, dan mengurangi polusi udara dari emisi gas buang dengan cara menambahkan zat aditif metanol pada bahan bakar. Analisis performa mesin yang dilakukan yaitu power, torsi, break mean effective pressure, efisiensi termal, dan specific fuel consumption, serta pengujian emisi gas buang kendaraan. Pada analisis uji performa mesin bensin, terlihat bahwa dengan penambahan metanol sebanyak 1,2%, terjadi peningkatan torsi, power, dan BMEP pada putaran 2500 rpm masing-masing sebesar 49,45%, 53,38%, dan 49,55%.
