Daftar Isi:
- The transesterification of free fatty acids in used cooking oil using superficial lime (CaO) as the catalyst in biodiesel production has been done. Used cooking oil was transesterified with methanol (the comparison total of waste cooking oil with total of methanol 320 mL : 80 mL) in preasence of CaO catalyst. The some catalyst was varied in 3% CaO, 5% CaO, 10% CaO, 15% CaO and 17% CaO. The transesterification was varied at 55 oC, 60 oC, dan 65 oC for 2 hour. The aim of the experiment was to look into the optimum conditions in the processing of waste cooking oil for biodiesel with superficial lime (CaO) catalyst. The result of research show that the optimum conditions from 15 variables have 14 variables standart of SNI 7182;2012 and SNI 04-7182-2006 and the minimum condition from total of catalyst is 17% CaO temperature 65oC variable. The result of research from the variable 10 % CaO temperature 65 C produces the highest of the heating of value is is 9499,44 cal/gr. Key words : transesterification, waste cooking oil, biodiesel, superficial lime (CaO) catalyst.
