Abstract
Penggunaan mesin diesel saat ini semakin banyak diikuti dengan penggunaan bahan bakar minyak yang meningkat juga. LPG (Liquified Petroleum Gas) adalah salah satu bahan bakar alternatif yang dapat digunakan untuk mesin diesel. Dengan sedikit memodifikasi pada bagian intake dan membuat konverter kit untuk memasukan LPG ke ruang bakar. Mesin diesel dapat berjalan dengan bahan bakar ganda (Diesel Dual Fuel). Pada penelitian ini bertujuan untuk mengetahui getaran dan kebisingan yang dihasilkan mesin diesel dual fuel LPG-Solar dan dibandingkan dengan mesin diesel berbahan bakar solar (single fuel). Penelitian ini dilaksanakan dengan metode eksperimen dimana mesin diatur pada RPM 2000 dengan variabel bebas berupa beban 1000 watt, 1500 watt, 2000 watt, 2500 watt, 3000 watt, dan pengaturan durasi bukaan injektor gas pada 3ms, 4ms, dan 5ms. Hasil yang didapat pada penelitian ini yaitu getaran yang dihasilkan mesin diesel dual fuel LPG-Solar dengan bukaan injektor 3ms sebesar 33,2 m/s², pada bukaan injektor 4ms sebesar 31,4 m/s², dan pada bukaan injektor 5ms sebesar 27,46 m/s². Sedangkan untuk tingkat kebisingan yang dihasilkan mesin diesel dual fuel LPG-Solar pada bukaan injektor 3ms sebesar 92,33 dBA, pada bukaan injektor 4ms sebesar 92,43 dBA, dan pada bukaan injektor 5ms sebesar 93,20 dBA.Hasil penelitian menunjukan getaran mesin diesel dual fuel LPG-Solar lebih rendah dibanding mesin diesel berbahan bakar solar (single fuel) dan kebisingan yang dihasilkan mesin diesel dual fuel LPG-Solar lebih tinggi dibanding mesin diesel berbahan bakar solar (single fuel).

The use of diesel engines today is increasingly followed by the use of fuel oil which is increasing as well. LPG (Liquified Petroleum Gas) is an alternative fuel that can be used for diesel engines. By slightly modifying the intake and making a converter kit to enter LPG into the combustion chamber. Diesel engines can run on dual fuel (Diesel Dual Fuel). This study aims to determine the vibration and noise produced by a dual fuel LPG-Diesel diesel engine and compared to a single fuel diesel engine (single fuel). This research was carried out using an experimental method where the engine was set at 2000 RPM with the independent variables being 1000 watts, 1500 watts, 2000 watts, 2500 watts, 3000 watts of load, and setting the duration of the gas injector opening at 3ms, 4ms, and 5ms. The results obtained in this study are the vibrations produced by the LPG-Diesel dual fuel diesel engine with a 3ms injector opening of 33.2 m/s², a 4ms injector opening of 31.4 m/s², and an injector opening of 5ms of 27.46 m/s². Meanwhile, the noise level produced by the LPG-Diesel dual fuel diesel engine at 3ms injector opening is 92.33 dBA, at 4ms injector opening is 92.43 dBA, and at 5ms injector opening is 93.20 dBA. dual fuel LPG-Diesel is lower than diesel engines fueled by diesel (single fuel) and the noise produced by dual fuel LPG-Diesel diesel engines is higher than diesel engines fueled by diesel (single fuel).
