Abstract

Biodiesel is an alkyl ester of long-chain fatty acids, the most common of which are methyl esters or ethyl esters. The manufacturing process involves esterification and transesterification. Traditional sources of biodiesel raw materials such as palm oil, soybeans, and jatropha have been widely studied. The princess palm, widely known as an ornamental plant, produces fruit containing seeds with quite high oil potential. This research aims to produce biodiesel and determine the physical and chemical properties from putri palm seeds. This research is experimental research with a quantitative descriptive approach. Putri palm seed oil is extracted using the soxhletation method with n-hexane solvent. The oil was then esterified using methanol with a catalyst of 1% sulfuric acid with a mole ratio of oil and methanol of 1:8 at a temperature of 60°C for 3 hours. The esterified oil is then transesterified using methanol and KOH with a methanol to oil ratio of 1:20 with KOH of 0.8% for 2 hours at a temperature of 60°C. This research has succeeded in making biodiesel from putri palm seeds. The biodiesel produced is in the form of a gel referred to as biodiesel gel with a yellowish brown color with a density of 1,236 gr/ml and a pour point of 36-38°C. The FFA/ALB value is 0.587%, the acid number is 1.177 mg KOH/g, the IOD number is 34.514 (g-I2/100 g), the saponification number is 63.19 mg KOH/g, the heating value is 48.088 MJ/Kg, and the cetane number 38,620. The IOD number, saponification number, and heating value meet the SNI standards for liquid biodiesel in general, while the cetane number and ALB value are close to SNI standards.

Abstract

Biodiesel consists of various long-chain methyl ester fatty acids which can be produced from renewable sources, for example, oil from palm seed extract (Adonidia merrillii). This research aims to determine the yield of extracted oil and biodiesel from putri palm seed oil. This research is experimental research with a quantitative descriptive approach. The extraction process was carried out using a Soxhlet apparatus with n-hexane solvent. The extracted oil is then tested for its characteristics, esterified and transesterified to produce biodiesel. Based on the research conducted, it was found that the oil yield from extraction was 0.47% or quite low. However, the biodiesel yield from putri palm seed oil is quite high, namely 87.66%. This research produces biodiesel in gel form at room temperature. This biodiesel gel is the first and newest discovery in the field of renewable energy sources. Biodiesel gel can be used as fuel for portable cooking equipment and food heaters to keep buffet and catering dishes warm.
