Abstract

Rice bran as rice milling waste is very promising to be used as raw material of oil producer such as biodiesel oil. The production process with the assistant of microwaves has been studied in this research. The production process was carried out in-situ where the extraction process of rice bran oil and the biodiesel formation reaction occur simultaneously in microwave radiation. Rice bran was obtained from Lamongan area with IR 64 type. The reaction was carried out in microwaves that had been modified by variation of operating conditions including reaction times (10, 30 and 50 min) and weight ratio of rice bran to methanol (1:4, 1:8, 1:12, 1:16 and 1:20). The results obtained are then analyzed by product yield and free fatty acid content. The optimum condition is obtained when the highest yield of the product with the lowest free fatty acid. The results showed that the optimum condition was obtained at reaction time of 30 minutes with the ratio of rice bran: methanol at 1:12.

Abstract

Shallot is one of the kitchen spices that is often used by the community. Shallot contains several useful compounds and one of them is phytosterol. Along with the development of science and technology, phytosterol can be used to reduce blood cholesterol levels and prevent heart disease, so it is very beneficial for human health. In this study, phytosterol compounds were identified and isolated. The dried onion is then pureed and sifted to 100 mesh. The sieved powder is then extracted by reflux extraction method within 6 hours. The results of the extract were then isolated by column chromatography and identified by thin layer chromatography (TLC). The TLC test uses -sitosterol as a standard and anisaldehyde reagent as a stain appearance. The TLC plate which had stained appearance was then analyzed using the TLC Scanner method. The results of the TLC test showed that the extract of positive red onion was purple and contained fitosterol. The results of the TLC Scanner also show that the peak and spectrum of the samples are the same as the standard -sitosterol and positively contain fitosterol.

Abstract

Material surface characteristics are the main criteria to be considered in catalyst design. The surface area and catalyst porosity determine activity and selectivity in catalytic reactions. In this research, synthesis of cobalt oxide, calcium fluoride and calcium fluoride cobalt oxide has been done. Characterization of solid sufaces is analyzed by using Nitrogen Gas Adsorption Method. The surface area of solids is analyzed by using SBET and SBJH Methods. Identification of mesoporous both qualitative and quantitative is analyzed by using BJH Method. The result of synthetic solid shows the pattern of isotherm adsorption type IV which is typical for mesoporous material. Surface measurements show the presence of cobalt oxide on a catalyst support marked by decreasing surface area, pore size and pore volume of catalyst support material.
