Abstract

Used cooking oil has the potential as biodiesel so that it can reduce environmental pollution. Transesterification of triglycerides in used cooking oil with an alcohol to form methyl esters of fatty acids or biodiesel and glycerol. The type of catalyst is one of the determinants of the transesterification reaction and coal fly ash has the potential to be used as a catalyst in the production of biodiesel. Therefore, this study aims to examine the effect of the oil-methanol ratio and the time of the transesterification of used cooking oil to the yield of biodiesel produced using an alkali-activated fly ash catalyst. Transesterification is carried out at 60 °C, the stirring speed is 700 rpm, and the amount of catalyst load is 4%. The result, the highest yield of biodiesel reached almost 89%. This biodiesel consists of 48.86% methyl oleate and 33.86% methyl palmitate and has a density that meets the Indonesian National Standard, which is 0.85 - 0.90 g/cm3. Finally, the BET test on the fly ash catalyst shows a catalyst surface area of ​​around 104.106 m2/g.

Abstract

Direct Methanol Fuel Cell (DMFC) can operate at low temperatures, but efficiency and performance are greatly influenced by the material. On the other hand, sulfonated ketone polyether ethers (sPEEK) which have high thermal resistance, ductile, chemical resistance and high mechanical properties, can be combined with chitosan which has good proton conductivity properties. The sPEEK-Chitosan membrane is known to have good mechanical and thermal resistance, but its conductivity is low. The addition of graphene oxide as a filler material can increase the proton conductivity due to its properties. This research was conducted with a completely randomized design of 1 factor to investigate the characteristics of the sPEEK-Chitosan composite membrane as the dependent variable and the addition of graphene oxide solution to the variables 0, 1, 3, 6, and 9% w/w as independent variables. The test results show that the water uptake is in the range of 8.82-33.34%, the swelling degree is in the range of 5.55-20.75%, and the ion exchange capacity is 0.1875-0.2714 meq/g. With this good character, the sPEEK-chitosan membrane with the addition of graphene oxide is a promising candidate for DMFC applications.
