The Nutrition Labeling and Education Act (NLEA) prohibits health claims for foods containing more than a certain amount of fat per serving. This disqualified level eliminates health claims for cooking oils since these products have approximately 14 grams of fat per serving, above the acceptable threshold. However, a number of scientific studies indicate that, from a heart-health perspective, co...

Cooking oil is one of the basic needs community to meet their daily needs, especially as a source fat. Based on Food and Agriculture Organization (FAO) in 2015 consumption vegetable food material reached 19 kg/capita. The results survey conducted by Indonesian Vegetable Oil Industry Association (GIMNI) 2017 proved that producers consumers cooking 8.144 million tons. Waste derived from plants su...

Energy obtained from renewable sources has increased its participation in the energy matrix worldwide, and it is expected to maintain this tendency. Both in large and small scales, there have been numerous developments and research with the aim of generating fuels and energy using different raw materials such as alternative crops, algae and waste cooking oil. Capparis spinosa seed (containing 3...

ABSTRACTAn oxidation stability is very important for a long-term storage of biodiesel. Some physical (density and viscosity) chemical properties (acid value, iodine peroxide value) were analyzed to predict the biodiesel produced from Waste Cooking Oil (WCO). WCO one potential feedstocks in Indonesia, which large cooking oil consumer. Biodiesel was by transesterification process 60 oC temperatur...

This study explores the potential of titanium oxide impregnated on calcium oxide (CaO-TiO2) as catalyst in transesterification of vegetable palm oil (VPO) to produce biodiesel. The biodiesel yield increased with catalyst calcination temperature and reaction time, and the usage of CaO-TiO2 led to higher biodiesel production when compared to reaction catalyzed by CaO. Biodiesel yield of 93.33% wa...

Biodiesel production from Waste Palm Cooking Oil (WPCO) is of interest to substitute fossil derived diesel fuel, due its renewable nature, cleaner emissions and non-toxic properties. Thus, in this study, biodiesel through transesterification process was optimized using immobilized lipase Candida rugosa WPCO collected the faculty’s cafeteria as a feedstock. Interaction between five operating fac...

The high level of consumption cooking oil will have an impact on increasing the waste produced. Using needed purification, including through adsorption process using activated carbon. This research aimed to study ability palm kernel shell carbon (PKSAC-AC260) compared standard (DAC or Decolorized Activated Charcoal by Sigma-Aldrich) in refining at various concentrations results showed that type...
