Cooking oil that is used repeatedly at high temperatures will reduce the quality of cooking oil. This will trigger the hydrolysis and oxidation processes that will change the characteristics of the oil, such as an increase in free fatty acid levels and pe... see more

Degradation of methyl violet using photocatalysis method has been investigated. In this study TiO2 was superimposed on the surface of the Bayah natural zeolite with two solvents, ethanol and distilled water. The activation of the Bayah natural zeolite usi... see more

Palm kernel shell (PKS) is one of the biomass with high potential that can be converted into chemicals. In this study, palm kernel shell (PKS) was converted by pyrolysis method to produce condensed liquid products, gas, and solid. The purpose of this stud... see more

This research was aimed to determine the differences of physical and chemical characteristics from three natural zeolites from Tasikmalaya, Bayah and Lampung areas and to examine the characteristics of the natural zeolite adsorption capability to the micr... see more

Natural zeolite (ZA) obtained from Wonosari, Indonesia, was treated with acetic acid (ZAA) or NaOH (ZAB), and the combination of both treatments (ZAAB) in order to increase the Si/Al ratio and catalytic performance on hydrotreatment of castor oil. The Si/... see more

Petroleum is still the primary energy used in the world. Its diminishing production is the trigger to find alternative energy to replace it. Biofuel is an alternative energy that has the potential to replace petroleum because it is renewable, environmenta... see more
