Abstract

Biodiesel adalah bahan bakar minyak yang dibuat dari bahan nabati berupa lemak atau minyak untuk digunakan pada mesin diesel. Oleh karena itu, minyak jarak merupakan salah satu bahan baku utama pembuatan biodiesel yang saat ini menjadi prioritas pemerintah Indonesia. Untuk dapat dimanfaatkan, minyak jarak dapat diubah menjadi bahan bakar alternatif dengan menjadikannya biodiesel yang dihasilkan dari reaksi transesterifikasi. Oleh karena itu penelitian ini akan membahas tentang analisis performa dan emisi gas buang pada mesin diesel berbahan bakar biodiesel minyak jarak. Biodiesel yang akan digunakan adalah campuran B35-Castor Oil untuk mendapatkan campuran Biodiesel B50CO (Petrodiesel 50% + Biodiesel sawit 27% + Biodiesel castor oil 23% ) dan B60CO (Petrodiesel 40% + Biodiesel sawit 21.5% + Biodiesel castor oil 38.5% ). Metode penelitian yang digunakan berbasis eksperimen, dengan menggunakan B50CO, B60CO dan B35 (Petrodiesel 65% + Biodiesel sawit 35%) sebagai pembanding. Hasil uji kinerja yang dilakukan menunjukkan bahwa penambahan biodiesel minyak jarak menurunkan kinerja. Di antara kedua bahan bakar tersebut, biodiesel B50CO tidak menurunkan performa yang signifikan sekitar 10,9%. Konsumsi bahan bakar B60CO kira-kira 4,7% lebih tinggi daripada B50CO. Torsi yang dihasilkan oleh B50CO kira-kira 0,2% lebih tinggi daripada B60CO. Hasil uji emisi NOx dilakukan dan diketahui bahwa kadar emisi NOx bahan bakar B50CO lebih baik dibandingkan bahan bakar B60CO, meskipun tidak signifikan, sekitar 11,2% lebih rendah dari B60CO, namun masih lebih tinggi dari B35 dalam hal emisi rata-rata sekitar 12,8% lebih tinggi

Biodiesel is fuel oil made from vegetable substance in the form of fat or oil for use in diesel engines. Therefore, castor oil is one of the main raw materials for making biodiesel which is currently a priority for the Indonesian government. In order to be utilized, castor oil can be converted into an alternative fuel by making it into biodiesel produced from the transesterification reaction. Therefore this experiment discuss the analysis of performance and exhaust emissions in diesel engines from castor oil biodiesel fuel. The biodiesel that will be used is a mixture of B35-Castor Oil to obtain a mixture of B50CO (Petrodiesel 50% + Biodiesel palm oil 27% + Biodiesel castor oil 23% ) and B60CO (Petrodiesel 40% + Biodiesel palm oil 21.5% + Biodiesel castor oil 38.5% ). The research method used is experimentally based, using B50CO, B60CO and B35 (Petrodiesel 65% + Biodiesel palm oil 35%) as a comparison. The results of performance tests conducted showed that the addition of biodiesel castor oil reduced performance. Between the two fuels, B50CO biodiesel does not offer a significant performance improvement over B60CO by about 10.9%. The fuel consumption of the B60CO is approximately 4.7% higher than the B50CO. The torque generated by the B50CO is approximately 0.2% higher than that of the B60CO. NOx emission test results were performed and found that the NOx emission levels of B50CO fuel were better to B60CO fuel, although this wasn’t significant, approximately 11.2% lower than B60CO, but still higher than B35 in terms of average emissions about 12.8% higher.
