Abstract

This research was conducted to separate used oil using a separator with activated carbon separation media and used cardboard. The treatment was carried out with time variations (minutes) 5, 10, 15, 20, and 25. With variations in the composition of used oil 2%, 4%, 6%, 8%, and 10%. Oil collection as a sample was carried out at a motorcycle workshop in Gampong Java, Banda Sakti District, Lhokseumawe City. The results of the study were tested for characteristics, pH, total dissolved solid (TDS), turbidity, and chemical oxygen demand (COD) in accordance with quality standards. These results show that pH, turbidity and TDS decrease with the longer the time left for sampling the separation results. Meanwhile, TDS and COD there are some samples that are still slightly below standard. With the influence of the residence time of sampling of sampling separation results, the results of the characteristic test are getting better and more stable. The results of this study show that used oil separation media using activated carbon and used cardboard can be used as a prevention of environmental pollution.

Abstract

This study aims to utilize kaolin as a membrane to reduce CO emissions in vehicles. The study was designed with constant variables including 10% PVA, 10% TiO2 catalyst, 8% starch adhesive, and 130 ml of distilled water, resulting in a total mixture weight of 140 grams. The membrane dimensions were 70 mm in length and 50 mm in diameter, with 19 holes of 3 mm each. Independent variables included kaolin carbon ratios (6:1, 5:1, 4:1, 3:2, 1:1) % of total mixture weight, engine rotation (1000, 2000, and 3000) rpm, and sintering temperatures (800°C, 900°C).The CO absorber is a component of the exhaust system designed to reduce carbon monoxide content in exhaust gases from internal combustion engines. CO absorbers typically consist of noble metal catalyst plates (such as platinum, palladium, and rhodium) embedded on ceramic or metal substrates. When exhaust gases pass through the CO absorber, catalytic reactions occur on the catalyst surface, converting carbon monoxide into carbon dioxide (CO2), which is safer for the environment. The study results showed that membranes with a composition of 65.8 g kaolin and 35 g activated carbon absorbed 84.64% of CO exhaust gases, achieving a final CO concentration of 0.80% at 1000 rpm. At 2000 and 3000 rpm, membranes with a composition of 72.8 g kaolin and 28 g activated carbon absorbed 90.45% and 92.31% of CO exhaust gases, with final CO concentrations of 0.57% and 0.54%, respectively. These results comply with the Ministerial Regulation No. 05 of 2006, which sets the CO emission threshold at 1.5% for the year 2007.
