Abstract

Biodiesel is one of alternative energy to replace fossil fuels from vegetable oil. The aims of this research were to produce biodiesel from castrol oil using heterogen catalyst La/NZA, to studythe effect of agitation speed and the ratio of impregnation La on NZA to the yield of biodiesel and to determine the characteristics of catalyst and biodiesel. The La/NZA catalyst is made bygrinding the natural zeolite to a size of -100 + 200 mesh, then the zeolite is activated using solution of HCL and NH4Cl, then it was dried. La is impregnated into NZA then dried using ovenand calcination. Production of biodiesel is carried out through two stages: esterification and trans-esterification. Before esterification, degumming process was done to remove impuritiesand gum contained in the oil. While in the trans-esterification process, variation of impregnation La on NZA are 0% La, 1% La and 3% La and variation of agitation speed are 300 rpm, 400 rpmand 500 rpm for 80 grams of castrol oil and methanol with the ratio of oil : methanol 1 : 9 was inserted to trans-esterification reactor, reaction lasted for 120 minutes at 60ºC. The highest yieldresulted on using 3%La/NZA catalyst with agitation speed 400 rpm which is 88.15%. Characteristics of the catalyst that has a surface area and ratio of Si/Al are large enough withbiodiesel produced in accordance with predefined standards (SNI 04-1782-2015).Keywords: biodiesel, La/NZA, castrol oil, transesterification.

Abstract

Biodiesel as an alternative diesel fuel are made from renewable biological resources, such as vegetable oils and animal fats. In Indonesia, fish production increase every year, so the waste of fish disposal usually is rising as well. Therefore, it is necessary to take advantage of new innovations of fish waste to biodiesel. In this research, conversion of the fish baung disposal to biodiesel has been done. By using a clay catalyst “lempung cengar”. Firstly, the fish disposal was heated for 4 hours. Then, oil was extracted from the fish disposal by pressed manually. Afterward, oil was converse to biodiesel by using a transesterification reaction with methanol as a reactan and a lempung cengar catalyst. The transesterification reaction was conducted under condition temperature 600C, stirring ± 150 rpm and a reaction time 210 minutes. In order to get a biodiesel yield maximally, variations of ratios sample and methanol (1:3; 1:6; 1:9), variation of a clay catalyst (0.5%, 1%, 1.5% w/w) were applied in this research.
