Biodiesel was successful produced from used cooking oil with Kaolin Catalyst. In this research, Biodiesel was produced in varied catalyst that prepared with Potassium Iodate, Potassium Iodinate and Methoxide. Kaolin was prepared from natural zeolite. The catalyst was analyzed with X-ray Diffraction for crystallinity, Scanning Electron Microscope for morphology, and Hammet Method for basicity. The crystallinity of catalyst that impregnated with Potassium Iodide, Potassium Iodate and Methoxide do not have significant L value. However, Methoxide Kaolin catalyst had the highest L value 354,3802, which is the highest crystallite size. K ion and methoxide that impregnated on the catalyst formed large number of porous agglomerates at the catalyst surfaces. Basicity test results showed that KI-Kaolin, KIO3− Kaolin, and Methoxide Kaolin had 0,188; 0,204, 0,24 base mmol. Biodiesel that used Methoxide Kaolin as catalyst on transesterification reaction produced highest biodiesel yield.

Soybean is also rich of nutrition such as minerals, vitamin B, complex carbohydrate and food fiber. Nevertheless central java is still lack of soybean. Winged bean (Psophocarpus tetragonolobus L) which its nutrition content is similar with soybean, is expected as the substitute of soybean. Winged bean can be used as source of protein by transforming it into composite flour which can be used as food product or edible film in food packaging. The usage of winged bean is limited, such as in tofu production. This is caused by strong bitter beany flavour of winged bean. The beany flavour is caused by the conversion of unsaturated fatty acid especially linoleate that catalyzed by lipoksigenase. In order to avoid the beany flavour, it’s urge to find an appropriate method which able to extract the oil of winged bean in the low or zero activity of lipoksigenase. In order to avoid the conversion of hydroperoxide fatty acid, we need to develop an effecti...

The composition of vitamins and minerals in potatoes is higher than wheat flour. Brownish color in potato flour has reduced consumer's interest, so it needs to be modified to improve the color and physicochemical properties of flour. Researchers are trying to modify the blanching process using hydrogen-rich water. Because hydrogen-rich water has antioxidants that can prevent the browning process (oxidation) potato flour, cheaper, safer, and healthier than chemical compounds. The purpose of this study was to optimize the blanching process for potato flour modification. Variation of the process used is soaking time at 30, 45, 60, 75, and 90 minutes. The optimal results of water content, ash content, reducing sugar content, protein, color, and swelling power were obtained at 75 minutes are 6.7%, 2.68%, 0.26%, 7.1%, 81.17, and 7 g/g. The quality of the modified potato flour met the p...

The catalyst was analyzed about surface area, X-Ray Diffraction (XRD) and performance test of catalyst for biodiesel production. An H-Zeolite catalyst was synthesized from natural zeolite with chemical treatment processing, impregnation KI/KIO3 and physical treatment. The results shows that the surface area of the catalyst by 27.236 m2/g at a concentration of 5% KI. XRD analysis shows peak 2-θ at 23.627o indicating that KI was impregnated on H-zeolite catalyst. The catalyst was tested in production of biodiesel using palm oil with conventional methods for 3 hour at temperature of 70-80 oC. The result for conversion Fatty Acid Methyl Ester (FAME) reached maximum value on 87.91% under production process using catalyst 5% KIO3-H zeolite.
