This research aims to convert corncorb into charcoal through a carbonization process and activated with CaCl2, then applied to improve the quality of peat water. Carbonization was carried out with klin drum method and ...

The transesterification of palm olein to fatty acid methyl esters was studied using NaOH/ZnO catalyst. The catalyst was prepared by impregnation with the loading of NaOH 25% w/w NaOH on ZnO calcined at 600 •c for 6 hours. ...

This research aims to synthesize biodiesel using a CaO catalyst from blood cockle shells impregnated with SiO2 from coconut fiber at a concentration of 3% w/w. The resulting catalyst was characterized using the Brunauer ...

The gonggong snail are widely consumed as a part of culinary tour that is in demanded by tourists. As a result, the waste of gonggong snail shells increases. Therefore, to reduce its waste, the gonggong snails are used ...

Energy reserves derived from oil and natural gas have a limited amount, so alternative renewable energy such as biodiesel is needed. Biodiesel can be derived from vegetable oil or animal fat. Oil from plants is more ...

Biodiesel (Fatty Acid Methyl Ester) is an alternative fuel other than petroleum. Therefore, intensive research is being carried out by researchers around the world to develop a more efficient, economical and environmentally ...

In this study, biodiesel was synthesized using crude palm oil (CPO) with a CaOSiO2 catalyst. CaO from blood clam shells and SiO2 from palm shell fly ash. CaOSiO2 catalyst synthesized using the wet impregnation method ...

The manufacture of biodiesel is usually used a transesterification reaction using an alkaline catalyst. The alkaline catalyst used in this study was K-CaO catalyst derived from shells of blood clams (Anadara granosa) ...

In this study, biodiesel was synthesized using crude palm oil (CPO) with a KOH/CaO catalyst from blood clam shells that had been calcined at 900 °C for 5 hours. KOH/CaO catalyst was synthesized using the sol-gel method ...
