Pengaruh Penambahan Ultra Fine Bubble pada Bahan Bakar Diesel terhadap Emisi Kendaraan Angkutan Pertanian | The Effect of Ultra Fine Bubble Addition to Diesel Fuel on Agricultural Vehicle Emissions

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan Ultra Fine Bubble (UFB) pada bahan bakar diesel terhadap emisi gas buang kendaraan angkutan pertanian. Bahan bakar yang digunakan terdiri atas Pertamina Dex dan Biosolar B40, masing-masing dengan dua perlakuan, yaitu tanpa UFB (normal) dan dengan UFB yang diproses melalui bubbling selama 50 menit. Pengujian dilakukan menggunakan mesin diesel kendaraan double cabin pada dua kondisi putaran mesin, yaitu idle (850 rpm) dan full throttle (4500 rpm). Parameter emisi yang dianalisis meliputi O2, CO2, CO, NOx, CxHy, dan opasitas. Data yang diperoleh dianalisis menggunakan uji-t untuk melihat perbedaan rata-rata antar perlakuan. Hasil penelitian menunjukkan bahwa penambahan UFB memberikan pengaruh terhadap perubahan nilai emisi, meskipun tidak semua parameter menunjukkan perbedaan yang signifikan. Pada beberapa kondisi, kandungan CO dan CxHy cenderung menurun saat menggunakan bahan bakar UFB, terutama pada putaran mesin tinggi. Selain itu, peningkatan kadar O2 dan penurunan NOx serta opasitas juga terlihat pada Biosolar B40 dengan perlakuan UFB. Temuan ini mengindikasikan bahwa teknologi Ultra fine bubble berpotensi meningkatkan efisiensi pembakaran dan menurunkan emisi gas buang pada mesin diesel kendaraan pertanian.

This study aims to examine the effect of ultra fine bubble (UFB) added to diesel fuel on the exhaust emissions of agricultural transport vehicles. The fuels used were Pertamina Dex and Biosolar B40, each with two treatments: untreated (normal) and treated with UFB through a 50-minute bubbling process. Emission testing was carried out using a diesel engine double cabin vehicle under two engine speed conditions: idle (850 rpm) and full throttle (4500 rpm). The measured emission parameters included O2, CO2, CO, NOx, CxHy, and opacity. Data were analyzed using a t-test to determine the average differences between treatments.The results showed that the addition of UFB influenced changes in emission values, although not all parameters showed statistically significant differences. In several cases, CO and CxHy levels tended to decrease with UFBtreated fuel, especially at higher engine speeds. In addition, increases in O2 and reductions in NOx and opacity were also observed with Biosolar B40 using UFB. These findings indicate that Ultra fine bubble technology has the potential to enhance combustion efficiency and reduce exhaust gas emissions in diesel engines for agricultural vehicles.
