Abstract

The development of alternative fuels is very necessary and a challenge for expert competent at this time. One of the alternative fuel is biomass utilization (biological materials) to produce biodiesel as a diesel fuel substitute. The process of making biodiesel using microwave heating using the reactor as a medium in microwave type of hydro distillation and equipped with high-intensity separator up to 400 KV.In the process of making biodiesel, there are several factors that affect the process of warming that is the molar ratio of waste cooking oil and methanol, the reaction temperature, reaction time, voltage, as well as the distance between the electrodes.The influence of various factors that can be seen from the results per cent yield and characteristics of biodiesel.From this research has done the optimum variations obtained on production process for obtained percent to yield the highest as well as products with characteristics in accordance with the standards of the SNI 7182-2015.Variation of 1:9 molar ratioobtained of 84.855% yield, reaction time 12 minutes obtained 86.04% yield, temperature of reaction 60 0Cobtained 88.91% yield, as well as voltage and electrode distance 3 cm and 266 KV obtained 74.73% yield

Abstract

This research is about recycling processed cooking oil into oil which can be used as raw material of biodiesel in a clean condition without dirt and low FFA, by using bagasse and banana peel as natural absorbent material and bleaching earth or pale soil as a chemical absorbent. Natural absorbent materials such as bagasse as well as banana peels that have been used as adsorbents can be directly used to absorb waste of waste oil into raw materials of biodiesel. From the result of the research, we found that the weight of adsorbent of optimum bagasse at SNI is 13% with free fatty acid 0.49%, acid number 0.37 mg KOH/mg Sample, number of sapling 187 and water content 0.43%. As well as the weight of the optimal banana husk adsorbent according to the SNI is 13% with free fatty acid 0.63%, the acid number 0.45 mg KOH/mg samples, the rate of sapding 135.58 and the moisture content of 0.43%. This indicates that the purifying tool jelantah oil by utilizing adsorbent of bagasse and banana peel skin as comparator to produce biodiesel raw material according to SNI. Whereas for chemical adsorbents, the results showed that the optimum conditions were obtained at 25% concentration and 60 minutes. For adsorbent 25% of free fatty acid acquisition was 0.49%, acidic value was 0.37, saponification number was 187 and water content was 0.018%. Where this number has produced biodiesel raw materials according to SNI.
