Oil is a non-renewable natural resource derived from petroleum. PT ALP Petro Industry is an industry that processes used oil back into new oil using vacuum distillation. The purpose of this study is to determine the outlet furnace temperature in optimizing each oil product by using the main pump, furnace, distillation column, exchanger, and tank. This research used vacuum distillation methodology by determining the temperature of the outlet furnace so that it gets the optimal oil product yield. This study uses a fixed variable used oil of raw material with a maximum water content of 0.1% and the flow rate of feed 4000 kg/h and uses a variable temperature of 376°C, 377°C, 378° C, 379°C, 380°C in the furnace outlet. The results showed that at outlet furnace temperature 376°C the yield of SLF oil products was 8.4%, LLF 35.0%, and HLF 16.6%. At temperature 377°C the SLF product yield was 12.2%, LLF 38.0%, and HLF 14.4%. At temperature 378°C the yield of SLF products was 14.9%, LLF was 40.8%, and HLF was 11.5%. At temperature 379°C the yield of SLF products was 15.6%, LLF 42.0%, and HLF 11.4%. At temperature 380°C the yield of SLF products was 16.3%, LLF 43.5%, and HLF 11.0%. Different outlet furnace temperatures produce different oil product yields because each fraction has different boiling points. The higher the outlet furnace temperature, the lower the HLF fraction oil product yield, and the higher LLF and SLF oil product yield. The lower the outlet furnace temperature, the higher the HLF oil product yield, and the lower LLF and SLF oil product yield.

Abstract Leachate from landfills, if left untreated, can lead to environmental pollution, especially if the leachate is discharged directly into the river. One way to reduce the environmental impact of seepage water is to treat the seepage water with a biofilter. The purpose of this study is to clarify the effect of leachate treatment with the use of biofilters. The method used in this study was to use laboratory-scale experimental methods. The biofilter used in this study was a combination of palm oil, sand, coconut shell charcoal, coconut fiber, gravel, and stone. The parameters measured in this study include pH, BOD, and COD. Based on the results of the studies conducted, biofilters have a significant impact on reducing the chemical content in the leachate. Biofilters have been shown to reduce the content of chemicals in osmotic water, so they do not pollute the environment, especially when it is discharged into rivers. The results showed that the COD and BOD values of the exudate were significantly reduced 6 weeks after treatment with the biofilter. The effectiveness of biofilms in reducing the chemical content in the leachate due to the presence of microorganisms growing in the biofilter layer is also based on the presence of biofilms formed by contact between the leachate and the biofilter.
