Abstract

Penelitian ini bertujuan untuk mengevaluasi performa mesin diesel yang menggunakan campuran bahan bakar coal water mixture (CWM) dan heavy fuel oil (HFO). CWM dibuat dengan mencampur batu bara low rank dengan air dan bahan pengikat, kemudian diuji karakteristik fisik dan kimianya, termasuk viskositas, titik nyala, nilai karbon, nilai hidrogen, nilai nitrogen, dan nilai kalori. Mesin diesel diuji menggunakan HFO murni serta campuran HFO-CWM dengan variasi 10%, 20%, dan 30% untuk mengukur torsi, daya, konsumsi bahan bakar spesifik, dan energi. Hasil pengujian menunjukkan bahwa penggunaan bahan bakar campuran CWM dan HFO dalam mesin diesel menghasilkan performa daya, torsi, dan energi yang meningkat dan konsumsi bahan bakar spesifik yang menurun. Penggunaan CWM dapat mengurangi ketergantungan pada minyak bumi dan memanfaatkan batu bara low rank yang melimpah di Indonesia. Penelitian ini mengindikasikan bahwa CWM memiliki potensi besar sebagai bahan bakar alternatif yang ekonomis dan berkelanjutan untuk kebutuhan energi di sektor maritim dan industri lainnya

This study aims to evaluate the performance of diesel engines using coal water mixture (CWM) and heavy fuel oil (HFO) fuel blends. CWM was prepared by mixing low rank coal with water and binders, then tested for physical and chemical characteristics, including viscosity, flash point, carbon value, hydrogen value, nitrogen value, and calorific value. The diesel engine was tested using pure HFO as well as HFO-CWM blends with variations of 10%, 20%, and 30% to measure torque, power, specific fuel consumption, and energy. The test results show that the use of CWM and HFO blended fuels in diesel engines results in increased power, torque, and energy performance and decreased specific fuel consumption. The use of CWM can reduce dependence on petroleum and utilize the abundant low rank coal in Indonesia. This research indicates that CWM has great potential as an economical and sustainable alternative fuel for energy needs in the maritime sector and other industries.
