Abstract

The availability of fuel oil is decreasing while the level of consumption is increasing. This encourages the need for the development of alternative energy to minimize the crisis. This study investigates the characteristics of fuel and automatic transmission combustion engines. The fuel used is butanol variations B7, B12 and B18 (7%, 12%, and 18%) and pertalite (RON-90). The gasoline engine used has a capacity of 110 cc with a compression ratio of 9.5:1, an automatic transmission system, and air conditioning. The performance test equipment used is the Dynotest-chassis type 50L-BRT. Fuel variations are applied to an engine performance test by using engine speeds of 3000-9000 rpm. The results showed that the use of 18% butanol increased the output power and thermal efficiency by 8.3 kW and 923.95 kPa at 8000 rpm. torque and MEP (average effective pressure) increased by 8 N.m and 923.95 kPa at 5000 rpm. Meanwhile, SFC (specific fuel consumption) decreased by 0.35 kg/kWh at 8000 rpm.

Abstract

Butanol as a fuel has a high oxygen content, so the combustion process will be more friendly to the environment. In this study, butanol will be mixed with RON-90 gasoline with a capacity of 5% (B5); 7%(B7); 10%(B10); 12%(B12); 15%(B15) and 18%(B18). The engine used is an automatic transmission with a capacity of 109.5cc with a compression ratio of 9.5:1. The test equipment for engine performance and exhaust emissions is the 50L BRT Super-Dyno and EPSG4 Gas Analyzer. The results showed that using B18 fuel for CO exhaust emissions decreased by 44% at an engine speed of 6000rpm. CO2 exhaust emissions have decreased by 47% at 8000rpm engine speed. HC exhaust emissions have decreased by 28% at 9000rpm engine speed. In contrast to NOx emissions, which increased by 22% at 9000rpm engine speed, this was due to the increasing temperature in the combustion chamber.

Abstract

Acetone-butanol-ethanol (ABE) is a preferred alternative energy for SI engines. This research uses an experimental method with an automatic SI engine, RON-90 fuel mixed with ABE1 (12:8:1)v/v, ABE2 (15:10:1)v/v and ABE3 (1i8:12:1) v/v. Engine speed is 4000-10000rpm, and compression ratio is 11.6:1. Emission and engine performance testing used EPSG4-Gas analyzer and Dynotest-chassis type 50L-BRT. This research aims to explore the mixture of RON-90 and ABE to optimize performance and exhaust emissions. This research shows that torque increases by an average of 14.7% at an engine speed of 6000rpm. Power increased significantly with an average value of 9.5% at an engine speed of 8000rpm, MEP increased by 0.5%, and thermal efficiency increased by 7%. SFC experienced a fairly optimal decrease of 15.6% on average. The exhaust gas emissions produced are CO and HC. The reduction in CO and HC occurred in the ABE3 variant with values of 8.2% and 1.6%, respectively.

Abstract

Mitra dalam PKM ini adalah UMKM opak jepit dengan merek Dua Putri, di Dusun Karang Ploso, Desa Klampok Kecamatan Benjeng, Kabupaten Gresik. Urgensi dari kegiatan ini adalah kapasitas produksi yang masih rendah dan kualitas kematangan produk yang kurang sempurna sehingga memerlukan sentuhan ilmu pengetahuan dan teknologi. Tujuan kegiatan ini adalah meningkatkan kapasitas dan kualitas produk mitra dan meningkatkan omset mitra. Permasalahan prioritas, 1) Peralatan produksi yang mudah berkarat, tidak higienis, kapasitas rendah, tidak ergonomis, dan tingkat kematangan produk tidak sama, 2) Wadah adonan menggunakan bahan plastik, 3) tempat pengemasan produk masih d lantai dialasi karpet, 4) karyawan tidak menggunakan APD, 5) Label dan merek masih kurang menarik, dan 6) belum ada pencatatan. Metode pelaksanaan dengan mengembangkan TTG mesin opak jepit, pelatihan dan pendampingan. Dampak kegiatan ini adalah adanya peningkatan kapasitas produksi mitra sebesar 60%, peningkatan omzet mitra sebesar 60%, peningkatan pengetahuan mitra sebesar 60%, dan peningkatan keterampilan mitra sebesar 60%.
