Karakteristik Palm Oil Biodiesel dan Performa Mesin Diesel : A Review
Get PDFThis article is a descriptive review study on palm oil biodiesel and its comparison with diesel fuel. Crude Palm Oil (CPO) is the best raw material for biodiesel because it has similar fuel specifications to diesel fuel. Fuel specifications according to American Standard Testing and Material (ASTM) and European Standard (EN) specifications are kinematic viscosity, density, and flash point. Palm oil biodiesel has a higher Brake Specific Fuel Consumption (BSFC) value and a lower Brake Thermal Efficiency (BTE) value compared to diesel. Palm oil biodiesel has higher NOx emissions, but lower HC and CO emissions, than diesel. In addition, palm oil biodiesel can be used in diesel engines with little or no modification. It has higher density, cooler flow problems and lower calorific value. Biodiesel can be blended with diesel and used in various concentration ratios to produce biodiesel blends that have properties that comply with international standards on diesel engine fuel and emissions, resulting in improved diesel engine performance and reduced emissions. The B20 and B30 biodiesel blend compositions are the best blend compositions based on the balance between engine efficiency and emission reduction due to the optimal balance between engine performance and environmental benefits. The B20 and B30 biodiesel blends show significant reductions in CO and HC emissions, achieving reductions of about 10% to 25% compared to diesel. The decrease in BTE and increase in BSFC are still proportional, so they do not compromise overall fuel efficiency too much
Pengaruh Perlakuan Kimia Alkalinasi dan Asetilasi terhadap Kekuatan Tarik dan Mikrostruktur Serat Abaka
Get PDFToday, environmental problems, especially soil pollution due to inorganic waste or waste that does not decompose, are a major problem and need to be solved, especially in developing countries with high populations such as Indonesia. One of the causes of soil pollution problems is the use of inorganic fibers such as glass fiber and carbon fiber. The use of materials that are not environmentally friendly in the industry will cause environmental problems due to nature's inability to decompose the glass fiber material in nature. The focus of this research is to reduce environmental pollution by using natural fibers such as abaca fiber as an alternative to inorganic fibers. This is due to its properties, namely: low density, good specific strength, low price, and a high biodegradable ability so that it can reduce glass fiber or carbon fiber waste that does not decompose. To support this, abaca fiber needs to be hydrophobic so that it becomes compatible with other materials when combined together with other materials. One of the ways that can be done is by alkaline chemical treatment and acetylation using KOH and CH3COOH. Chemical treatment was carried out by dipping abaca banana fibers into a solution of alkaline compounds and acetylated compounds KOH and CH3COOH with a concentration of 5 M and 10 M for 4 hours. After chemical treatment, the abaca banana fibers were characterized for mechanical properties using ASTM D 3379 standards to determine the tensile strength of the fibers and using an optical microscope to determine the microstructure of the abaca fibers
