Abstract

In Indonesia, plastic waste has become an important problem at this time, because it causes environmental pollution problems. With this, further action is needed regarding the treatment of waste utilization, one of which is by converting waste into liquid fuel. Some types of rubbish that we often encounter are plastic bottles such as plastic cups, plastic bottle caps, children's toys and margarines and others, which is one of the types of PP (polypropylene) waste. The development of current plastic waste treatment technology is to convert plastic waste into fuel oil by utilizing plastic waste to be processed as plastic fuels such as premium fuel, diesel and kerosene. Polypropylene type plastic is the type of plastic that is most widely used in daily life because it has good mechanical properties with low density, heat and moisture resistance, and has good dimensional stability. Some of the technology used to convert plastic waste, among others, by using the method of high temperature (Thermal Cracking). In this study, researchers designed a Thermal cracking device, namely an Incinerator, a plastic waste smelter with high temperature, where the modification of this tool is to use used fuel oil or residual oil. In this study, the researcher analyzed the burning time, the amount of waste mass needed for the melting process in the Incinerator. In this research, a fuel equivalent of 1.5 liters of premium fuel was produced with 10 kg of plastic waste burned in the incinerator with a burning time of 125 minutes of the pyrolysis process, with a combustion temperature of 180-250 degrees Celsius.

Abstract

Indonesia as one of the largest producing and exporting countries of crude palm oil (CPO). However, Indonesia still has not utilized the potential of the waste that generated by using CPO as cooking oil, namely used cooking oil. The high content of free fatty acids (FFA) in used cooking oil will cause the saponification reaction and interfere the processing into biodiesel. Cocoa bean shell charcoal (Theobroma cacao L) has a K2CO3 content similar to its commercial product, and contains some traces of silicates and sulfates so that it can increase the efficiency of reducing free fatty acids. In this study, tests were carried out to reduce FFA levels in used cooking oil using charcoal from cocoa bean husks activated with HCl, varying the concentrations of 6, 8 and 10 Molar, as well as the temperature treatment during the process of mixing used cooking oil with activated charcoal adsorbent, which was 75 , 100, and 150°C. The best FFA reduction results were found in the A3T2 reactor which reached 80%, where the best HCl concentration was 10 Molar and the temperature of the mixing process with the adsorbent was 100°C and produced a biodiesel yield of 75%. The quality of the biodiesel produced complies with SNI 7182-2015 standards, 867 kg/m3 of density, 0.5 mg KOH/g of acid number, 1.52 cSt of kinematic viscosity, 48.081 MJ/kg of calorivic value and 143.99%- mass of methyl ester content.
