Abstract

Gas buang yang dihasilkan oleh motor diesel dapat mencemari alam, terutama untuk gas Sulfur (SOx) berpotensi menyebabkan terjadinya hujan asam yang dapat merubah komposisi tanah yang merugikan bagi makhluk hidup. Oleh karena itu, maka kandungan sulfur dalam bahan bakar harus dikurangi. Salah satu metode untuk mengurangi kandungan sulfur pada bahan bakar adalah adsorpsi menggunakan padatan. Pada penelitian ini akan dipelajari pengaruh desulfurisasi marine diesel oil (MDO) dengan metode adsorpsi menggunakan karbon aktif terhadap performa mesin diesel satu silinder empat langkah. Penelitian ini berbasis eksperimen dimana bahan bakar marine diesel oil (MDO) dicampur dengan karbon aktif dengan variasi 4 g/l, 8 g/l, 12 g/l yang kemudian diaduk selama 2 jam dan disaring serta dilakukan uji karakteristik pada bahan bakar tersebut. Setelah itu dilakukan uji coba penggunaan bahan bakar yang telah didesulfurisasi pada mesin diesel. Pada penelitian ditemukan bahwa karbon aktif dapat mengurangi kandungan sulfur pada bahan bakar marine diesel oil (MDO) dengan hasil uji kandungan sulfur terendah sampai tertinggi pada penelitian ini secara berurutan adalah MDO AC-12 g/l sebesar 0,34% m/m, MDO AC-8 g/l sebesar 0,39% m/m, MDO AC-4 g/l sebesar 0,41% m/m, dan MDO AC-0 g/l sebesar 0,41% m/m. Dan hasil analisa uji performa untuk daya dan torsi terbesar dicapai oleh bahan bakar MDO AC-4 g/l dengan selisih daya sebesar 10,76% dan selisih torsi sebesar 17,47% dibandingkan daya dan torsi yang dicapai bahan bakar MDO AC-0 g/l. Sedangkan untuk SFOC terendah didapatkan oleh MDO AC-4 g/l dengan selisih sebesar 3,14% dibandingkan dengan bahan bakar MDO AC-0 g/l.

The exhaust gas produced by diesel motors can pollute nature, especially for Sulfur gas (SOx) has the potential to cause acid rain which can change the composition of the soil which is detrimental to living things. Therefore, then the sulfur content in the fuel should be reduced. One of the methods to reduce the sulfur content in fuel is adsorption using solids. In this study, the effect of desulfurization of marine diesel oil (MDO) with the adsorption method using activated carbon will be studied on the performance of four-stroke single-cylinder diesel engines. This research is based on an experiment where marine diesel oil (MDO) fuel is mixed with activated carbon with a variation of 4 g/l, 8 g/l, 12 g/l which is then stirred for 2 hours and filtered and tested the characteristics of the fuel. After that, a trial of the use of fuel that has been deesulfurized in diesel engines is carried out. In the study, it was found that activated carbon can reduce the sulfur content in marine diesel oil (MDO) fuel with the lowest to highest sulfur content test results in this study sequentially, namely MDO AC-12 g/l by 0.34% m / m, MDO AC-8 g/l by 0.39% m / m, MDO AC-4 g/l by 0.41% m / m, and MDO AC-0 g/l by 0.41% m / m. And the results of the performance test analysis for the largest power and torque were achieved by MDO AC-4 g/l fuel with a power difference of 10.76% and a torque difference of 17.47% compared to the power and torque achieved by MDO AC-0 g/l fuel. As for the lowest SFOC, it was obtained by MDO AC-4 g/l with a difference of 3.14% compared to MDO AC-0 g/l fuel.
