Ethanol mulai digunakan sebagai bahan bakar substitusi bensin sebagai bahan bakar mesin pembakaran dalam. Penelitian ini bertujuan untuk menguji pengaruh kandungan ethanol dalam bensin. Bensin yang digunakan diberikan ethanol 8%, 10%, dan 12% v/v. Pengujian dilakukan menggunakan sepeda motor 4 langkah bertransmisi CVT masing-masing berkapasitas 115 cc dan 125 cc. Sepeda motor diuji di atas chassis dynamometer untuk mensimulasi hambatan yang dialami sepeda motor ketika melaju di jalan aspal. Pengujian dilakukan pada kecepatan 10 km/j, 20 km/j, 30 km/j, 40 km/j, dan 50 km/j. Hasil pengujian menunjukkan bahwa ethanol meningkatkan jarak tempuh untuk semua jenis bensin dan semua kandungan ethanol. Peningkatan jarak tempuh tertinggi diperoleh untuk kandungan ethanol 10% dibanding tanpa ethanol. Kata kunci: ethanol, jarak tempuh, konsumsi bahan bakar.
