Abstract
Minyak bumi merupakan sumber energi yang tidak dapat diperbaharui. Tingginya tingkat ketergantungan masyarakat dunia pada minyak bumi, mendorong eksplorasi yang besar-besaran sehingga menyebabkan cepat habisnya cadangan minyak bumi. Berbagai penelitian dilakukan untuk mencari sumber energi altematif yang efisien, ramah lingkungan, tersedia dalam jumlah besar dan mampu menurunkan penggunaan minyak bumi. Penggunaan minyak kelapa sawit atau crude palm oil yang ditranseterifikasi menjadi palm methyl ester (PME) sebagai pencampur bahan bakar motor diesel ingin diketahui besarnya unjuk kerja dan emisi gas buang. Penelitian menggunakan bahan bakar campuran PME dan solar degan komposisi B 35, B 40, B 45, B 50, B 55, B 60, B 65 dan sebagai pembanding digunakan B 0 dan B 100. Uji coba dilakukan di Laboratorium Bahan Bakar dan Motor Pembakaran Dalam Jurusan Teknik Mesin FTI-JTS dengan menggunakan mesin diesel KAMAKM178FS. Hasil pengujian menunjukkan torsi, daya, bmep B 35, B 40, B 45, B 50, B 55, B 60 dan B 65 turun dengan prosentase sama dengan nilai yaitu 15,43%, 6,55%, 7,57%, JJ ,80%, 9,14%, 12, 52% dan 6,73%. Untuk nilai bsfc naik dengan prosentase 18,99%, 7,87%, 13,49%, 24,29%, 21,66%, 25,27% dan 15,53%. Besarnya nilai ejisiensi thermis untuk B 40 naik 1,02%, tetapi untuk B 35, B 45, B 50, B 55, B 60 dan B 65 mengalami penurunan sebesar 5,92%, 4,41 %, 12,04%, 10,80%, 12,12% dan 10,36%. Emisi yang ditimbulkan berupa opasitas turun 4,71%, 3,91%, 5,59%, 5,29%, 7,73%, 7,98%dan 7,70%

Petroleum is a non-renewable energy source. The high level of dependence of the world community on petroleum has encouraged large-scale exploration, resulting in the rapid depletion of petroleum reserves. Various studies have been conducted to find alternative energy sources that are efficient, environmentally friendly, available in large quantities and able to reduce petroleum use. The use of palm oil or crude palm oil transetherified into palm methyl ester (PME) as a diesel engine fuel mixer aims to determine the performance and exhaust emissions. The study used a mixture of PME and diesel fuel with compositions of B 35, B 40, B 45, B 50, B 55, B 60, B 65 and as a comparison used B 0 and B 100. The trial was conducted at the Fuel and Internal Combustion Engine Laboratory of the Department of Mechanical Engineering FTI-JTS using a KAMAKM178FS diesel engine. The test results show that torque, power, bmep B 35, B 40, B 45, B 50, B 55, B 60 and B 65 decreased by the same percentage as the values, namely 15.43%, 6.55%, 7.57%, JJ ,80%, 9.14%, 12, 52% and 6.73%. For the bsfc value increased by a percentage of 18.99%, 7.87%, 13.49%, 24.29%, 21.66%, 25.27% and 15.53%. The value of thermal efficiency for B 40 increased by 1.02%, but for B 35, B 45, B 50, B 55, B 60 and B 65 it decreased by 5.92%, 4.41%, 12.04%, 10.80%, 12.12% and 10.36%. The resulting emissions in the form of opacity decreased by 4.71%, 3.91%, 5.59%, 5.29%, 7.73%, 7.98% and 7.70%
