Abstract

The search for renewable alternative energy must be developed, one of which is biodiesel. Seed Calophyllum inophyllum has a fairly high oil content of about 71.4% by weight, has great potential when used as raw material for making biodiesel. The purpose of this research was to synthesize biodiesel from Calophyllum inophyllum oil through the transesterification process using base lewis catalyst with microwave assisted, comparing the performance of sodium acetate to potassium hydroxide, knowing the amount of catalyst required to obtain the best biodiesel, and knowing the optimum power in the manufacture of biodiesel, The first step of making Calophyllum inophyllum biodiesel is degumming process, then continued with esterification. The next process is transesterification, followed by purification of biodiesel. The catalysts used are CH3COONa, and KOH. From the results, Calophyllum inophyllum oil can be used as biodiesel feedstock, the best operating conditions for base catalyst at 300 W power, 1% (w/w) concentration, produced the best yield is 96% (for KOH catalyst) and 87% (for CH3COONa catalyst).

Abstract

Methyl ester sulfonate is an anionic surfactant that can be synthesized from palm oil as a raw material with the addition of sodium bisulfite and calcium oxide catalyst through transesterification and sulfonation process using microwave-assisted heating. The effect of microwave-assisted heating in the transesterification-sulfonation process was investigated in this study. The transesterification process was carried out using a microwave power of 300 watts for 10 minutes with an addition of a KOH catalyst of 1%. The transesterification process gave a result of palm oil methyl ester with a yield of up to 98% and density of 0.8546 gr/ml, and kinematic viscosity of 3.19 cSt. The sulfonation process is carried out using palm oil methyl ester and sodium bisulfite with a mole ratio of 1:3 and calcium oxide catalyst of 1.5% with the microwave power of 300 watts while varying the sulfonation time and temperature. The physicochemical properties of methyl ester sulfonate were analyzed, and the sulfonate group was characterized using FTIR. The optimum condition gave a yield of up to 98.68%, the density of 0.8657 gr/ml, viscosity of 3.75 cSt, pH of 2.12, and surface tension of up to 27.34 dyne/cm at a temperature of 100oC and sulfonation time of 40 minutes.

Abstract

In this study, the optimization and characterization of the colorant extraction process from sappan wood were carried out using the ultrasound-assisted extraction method. Sappan is proposed as a source of natural material wealth, producing a natural red colorant that is being needed by the community in the food sector. Based on this research, the optimum operating conditions for the extraction of sappan wood were obtained using a frequency of 40 kHz, a temperature of 60 °C, a ratio of 0.0050 g mL-1, an extraction time of 20 min, and the use of 60% ethanol solvent. Sappan wood extract created a yellow to reddish orange color at acidic pH (2-6), red at neutral pH (7) and shifted towards purplish red with increasing pH. The extract was qualitatively positive containing quinone, flavonoid, quinone, and tannin compounds, as well as several phenolic compounds detected in the Gas Chromatography Mass Spectroscopy qualitative test.
