dc.description.abstract | Biodiesel is a source of fuel alterative energy derived from vegetable oil that is from crude palm oil / renewable and environmental savety.. Processing of biodiesel from crude palm oil perform through transesterification and esterification. And then biodiesel is mixed with diesel fuel with composition 10% : 90% : 20% : 80% : 30% : 70% and so on. The characterization is carried out by measuring, viscosity, density, falsh point and caloric value, and then variation of result experiments result of examination reveal the value of viscosity 3,1-4,5 cSt, density 819-861 kg/m3, flash point 72-162c and calor value 54,92-30,51 MJ/kg. Result from some article at mixed composition 30% : 70% having maximum energy 5.36 HP and efficiency 97,64%, this value come near maximum energy of diesel fuel that is 5,41HP and efficiency 98.30%. the agriculture machine perfom biodiesel mixture 30% at Yanmar TF 5,5 L-di having technical activity which much the same with engine diesel, good of maximum enegy torsian as well as giving better environment savety | en_US |
dc.description.abstract | Biodiesel merupakan salah satu sumber energi alternatif bahan baker yang diperoleh dari hasil minyak nabati yaitu dari kelapa sawit, dapat diperbaharui dan ramah lingkungan. Pengolahan biodiesel dari kelapa sawit dapat dilakukan dengan proses esterifikasi dan transesterifikasi. Kemudian biodiesel an solar dicmpur denan komposisi campuran 10% : 90% : 20% : 80% : 30% : 70% dan seterusnya Karakteristik yang dilakukan meliputi sifat-sifat fisika : ciskositas, densitas, titik nyala dan nilai kalor, kemudian divariasikan dengan hasil dari beberapa artikel . Berdasarkan hasil pengujian nilai viskositas 3 1-4 cSt, densitas 819-861 kg/m3, titik nyala 72-1620C dan nilai kalor 54,92-30,51 MJ/kg. Hasil dri beberapa artikel pada komposisi campuran 30%:70% mempunyai dya maksimum 5.36 HP, efisiensi 98,30%. Pada lat mesin pertanian penggunaan campuran biodiesel 30% ada mesin diesel Yanmar TF5,5 L-di, mempnyai unjuk kerja teknis yang hamper sama dengan solar,baik daya maksimum torsi dan juga memberikan dampak lingkungan yang lebih baik | en_US |
