In this study, optical and thermal properties of normal grade and winter grade palm oil biodiesel were investigated. Surface Plasmon Resonance and Photopyroelectric technique were used to evaluate the samples. The dispersion curve and thermal diffusivity were obtained. Consequently, the variation of refractive index, as a function of wavelength in normal grade biodiesel is faster than winter gr...

Abstract—Five palm oil ether monoesters utilized as novel biodiesels were synthesized and structurally identified in the paper. The investigation was made on the effect of ether species on physicochemical properties of the palm oil ether monoesters. The results showed that density, kinematic viscosity, smoke point, and solidifying point increase linearly with their –CH2 group number in certain ...

Rapid deforestation in Sumatra, Indonesia is presently occurring due to the expansion of palm oil and rubber production, fueled by an increasing global demand. Our study aimed to assess changes in soil-N cycling rates with conversion of forest to oil palm (Elaeis guineensis) and rubber (Hevea brasiliensis) plantations. In Jambi Province, Sumatra, Indonesia, we selected two soil landscapes - loa...

Palm oil production creates negative externalities, e.g., through intensive fertiliser application. Policies to limit externalities need an effective, sustainable and efficient measure We use a business simulation game in a framed field experiment in Indonesia to test ex ante different incentives for reducing such negative externalities. This setting allows inclusion of adequate contextual feat...

The comparative hypocholesteremic effect of feeding palm oil and palm oil mill effluent (POME) was investigated in male albino rats. Diets were prepared and designed to contain 50% of energy as carbohydrate, 35% as fat, and 15% as protein. Groups of six rats were each fed one of these diets, while a group was fed pelletized mouse chow which served as the control. Feeding on palm oil and POME le...

The waste agriculture materials cause environment pollution, recycle of these materials help sustainable development. This study focused on the impact of used oil palm shell ash on the compressive and flexural strengths of cement mortar. Two different cement mortar mixes have been designed to investigate the impact of oil palm shell ash on strengths of cement mortar. Quantity of 4% oil palm she...

• After palm oil was brought to South East Asia from central Africa in the 20 century the worldwide production has grown by 65 percent over the past decade. Demand is still increasing, especially after the European Union agreed to its 10 percent target for biofuels in their total transport consumption. • As biggest and second biggest producer of palm oil Indonesia and Malaysia account together ...

Palm oil mill effluent from the palm oil processing industry has been documented as a cause of severe damages to aquatic systems and a significant increase in greenhouse gases. This study was designed to use electrocoagulation for the pre-treatment of palm oil mill effluent to simultaneously reduce the pollutants and produce hydrogen gas. In this research, response surface methodology was appli...
