Abstract

Penelitian yang dilakukan penulis bertujuan untuk menganalisis kadar emisi Nitrogen Oksida (NOx) yang dihasilkan oleh mesin diesel menggunakan bahan bakar biodiesel minyak biji jarak. Penelitian dilakukan dengan menggunakan (Selective Catalytic Reduction) SCR system dengan metode eksperimen. Katalis yang digunakan dalam SCR system yaitu zeolitebentonit dan agen pereduksinya yaitu larutan urea. Pada penelitian ini, penulis membandingkan dua bahan bakar sebagai pembanding dengan dua kondisi yang berbeda juga yaitu tanpa SCR system dan dengan SCR system. Pada penelitian ini persentase kenaikan kadar emisi terbesar dari pertamina dex ke B50 jarak kepyar terjadi pada beban 75% yaitu sebesar 24,53%. Dan penurunan emisi terbesar dari pertamina dex tanpa SCR ke pertamina dex dengan SCR terjadi pada beban 100% yaitu sebesar 23,71%. Penurunan emisi terbesar pada bahan bakar B50 jarak kepyar tanpa SCR ke B50 jarak kepyar dengan SCR terjadi pada beban 50% yaitu sebesar 23,38%. Hasil penelitian menunjukkan bahwa penggunaan biodiesel meningkatkan kadar emisi NOx jika dibandingkan dengan bahan bakar konvensional. Namun dengan penambahan SCR system berbasis zeolit-bentonit sebagai katalis dan larutan urea sebagai agen pereduksi mampu menurunkan kadar emisi NOx secara signifikan. Hal ini menunjukkan bahwa SCR system berbasis zeolit-bentonit sebagai katalis dan larutan urea sebagai agen pereduksi efektif dalam mereduksi emisi NOx yang dihasilkan mesin diesel yang menggunakan biodiesel minyak jarak.

The research conducted by the author aims to analyze the emission levels of Nitrogen Oxide (NOx) produced by diesel engines using castor seed oil biodiesel fuel. The research was conducted using the SCR (Selective Catalytic Reduction) system with an experimental method. The catalyst used in the SCR system is zeolite-bentonite and the reducing agent is urea solution. In this study, the authors compared the two fuels as a comparison with two different conditions, namely without the SCR system and with the SCR system. In this study, the largest percentage increase in emission levels from Pertamina dex to B50 kepyar occurred at 75% load, which was 24.53%. And the biggest reduction in emissions from Pertamina Dex without SCR to Pertamina Dex with SCR occurred at 100% load, which was 23.71%. The biggest reduction in emissions from B50 rangefinder fuel without SCR to B50 rangefinder with SCR occurred at 50% load, namely 23.38%. The results showed that the use of biodiesel increased NOx emission levels when compared to conventional fuels. However, the addition of a zeolite-bentonite-based SCR system as a catalyst and urea solution as a reducing agent was able to significantly reduce NOx emission levels. This shows that the SCR system based on zeolite-bentonite as a catalyst and urea solution as a reducing agent is effective in reducing NOx emissions produced by diesel engines using castor oil biodiesel.
