Abstract
Bahan bakar biodiesel termasuk bahan bakar renewable, bahan bakar ini berasal dari bahan baku organik. Pada penelitian ini dilakukan pengujian performa dan emisi gas buang yang dihasilkan dari bahan bakar biodiesel dengan campuran Dex. Untuk proses blending menggunakan persentase volume B30 (30% Minyak Jelantah + 70% Dex), B50 (50% Minyak Jelantah + 50% Dex), B70 (70% Minyak Jelantah + 30% Dex). Bahan bakar tersebut akan diujikan untuk memperoleh performa engine dengan metode pengujian constant speed dan uji emisi, pada mesin diesel tipe KM 186Fa. Dari hasil pengujian diperoleh nilai performa tertinggi pada pembebanan 2000 Watt, pertamina dex menghasilkan daya (Ne) sebesar 2830,8823Watt, torsi 8,3918 n.m, BMEP 252154,3588 Pa, BSFC 0,3338 kg/kWh, dan thermal efficiency 22,83%. Kedua dari bahan bakar B-30 menghasilkan daya (Ne) sebesar 2827,6471 Watt, torsi 8,3848 n.m, BMEP 251944,3532 Pa, BSFC 0,3418 kg/kWh, dan thermal efficiency 23,77%. Ketiga dari bahan bakar B-50 menghasilkan daya (Ne) sebesar 2821,1765 Watt, torsi 8,3656 n.m, BMEP 251367,8215 Pa, BSFC 0,3549 kg/kWh, dan thermal efficiency 23,69%. Keempat dari bahan bakar B-70 menghasilkan daya (Ne) sebesar 2814,7059 Watt, torsi 8,2847 n.m, BMEP 248937,0104 Pa, BSFC 0,3676 kg/kWh, dan thermal efficiency 23,62%. Pada hasil pengujian emisi menggunakan smoke oppacity meter, Pada pertamina dex memiliki nilai opasitas sebesar 3,5%HSU, B-30 sebesar 4,5%HSU, B50 sebesar 8,1%HSU, B-70 sebesar 9,8%HSU. =======================================================================================================================================
Biodiesel fuel is a renewable fuel derived from organic raw materials. In this study, performance and exhaust emissions were tested for biodiesel fuel mixed with Dex. For the blending process, the following volume percentages were used: B30 (30% waste cooking oil + 70% Dex), B50 (50% waste cooking oil + 50% Dex), and B70 (70% waste cooking oil + 30% Dex). The fuel will be tested to determine engine performance using constant speed testing and emission testing methods on a KM 186Fa diesel engine. The test results showed the highest performance at a load of 2000 Watts, with Pertamina Dex producing power (Ne) of 2830.8823 Watts, torque of 8.3918 n.m, BMEP of 252154.3588 Pa, BSFC of 0.3338 kg/kWh, and thermal efficiency of 22.83%. Second, the B-30 fuel produced a power output (Ne) of 2827.6471 Watts, torque of 8.3848 N·m, BMEP of 251944.3532 Pa, BSFC of 0.3418 kg/kWh, and thermal efficiency of 23.77%. Third, the B-50 fuel produces power (Ne) of 2821.1765 Watts, torque of 8.3656 N·m, BMEP of 251367.8215 Pa, BSFC of 0.3549 kg/kWh, and thermal efficiency of 23.69%. Fourth, the B-70 fuel produced power (Ne) of 2814.7059 Watts, torque of 8.2847 n.m, BMEP of 248937.0104 Pa, BSFC of 0.3676 kg/kWh, and thermal efficiency of 23.62%. In emission testing using a smoke opacity meter, Pertamina Dex had an opacity value of 3.5%HSU, B-30 of 4.5%HSU, B50 of 8.1%HSU, and B-70 of 9.8%HSU.
