Abstract
Biodiesel dari minyak biji nyamplung telah diproses melalui 2 tahap, yakni reaksi esterifikasi dengan menggunakan katalis PdCl₂ serta reaksi transesterifikasi dengan katalis KOH. Karakterisasi yang meliputi beberapa sifat fisik dan kimia antara lain densitas, viskositas, bilangan asam, bilangan penyabunan, bilangan setana, serta kalor pembentukan dan pembakaran. Kalor pembakaran biodiesel yang diperoleh dengan menggunakan bom kalorimeter yakni 9050 kal/g, sedangkan kalor pembentukan yang diperoleh melalui program HyperChem™ yaitu 9207,11 kal/g. Perbedaan ini disebabkan oleh faktor penyusun biodiesel yang berbeda, untuk kalor pembakaran, yang dihitung adalah metil ester, trigliserida, metanol dll, sedangkan kalor pembentukan yang dihitung adalah hanya metil ester. Adapun sifat fisika dan kimia biodiesel minyak biji nyamplung antara lain berwarna kuning jernih dengan bau yang khas dan memiliki densitas (T=30°C) 0,9022 g/mL, titik nyala 152°C, viskositas kinematik (T=30°C) 11,7153 cSt, bilangan setana 74,7, bilangan asam 34,05 mg KOH/g.

Biodiesel from nyamplung seed oil was proceed in 2 stages, the esterification reaction using the catalyst PdCl₂ and transesterification using KOH catalyst. Characterization of seed oil biodiesel nyamplung was done by several physical and chemical properties such as density, viscosity, acid number, saponification number, cetane number and heat of combustion and formation. Heat of combustion of biodiesel obtained by a bomb calorimeter is 9050 cal/g, while the heat formation obtained by HyperChem™ program that is 9207,11 cal/g. This difference results cause of constituent factors, to heat combustion, which is calculated is methyl esters, triglycerides, methanol, etc., whereas the calculated heat formation is the only methyl ester. The physical and chemical properties of seed oil biodiesel nyamplung include clear yellow with a distinctive odor and has a density (T = 30°C) 0.9022 g/mL, flash point 152°C, kinematic viscosity (T = 30°C) 11.7153 cSt, cetane number 74.7 and acid number 34,05 mg KOH/g.
