Abstract


Pada penelitian ini, biodiesel diproduksi dari new feedstock minyak Kemiri Sunan. Minyak Kemiri Sunan merupakan minyak non edible sehingga sangat menarik untuk diproduksi sebagai biodiesel. Minyak Kemiri sunan diproduksi dengan dua tahapan reaksi yaitu reaksi esterifikasi dan transesterifikasi menggunakan katalis H2SO4 dan KOH. Reaksi esterifikasi telah dilakukan perbandingan minyak:metanol (3:1) selama 2 jam. Reaksi transesterifikasi dilakukan dengan variasi konsentrasi katalis KOH (0,5; 1,0; 1,5; 2,0 %berat minyak), rasio minyak:metanol (1:1; 2:1; 3:1 (berat/berat)), dan suhu reaksi 65 selama 1 jam. Yield dan sifat biodiesel dianalisis dengan Chromatography Gas (GC) dan ASTM D 6751. Yield optimum biodiesel diperoleh sebesar 96,91%, pada kondisi optimum konsentrasi katalis KOH 1 % berat minyak, rasio minyak:metanol 1:1 (berat/berat) dan suhu reaksi 65oC. Biodiesel berbahan dasar minyak kemiri sunan mempunyai rentang angka asam 0,41-0,56 mgKOH/gram, densitas 0,89-0,91 gram/cm3, viscositas 8,28-12,70 cSt, angka setana 58,2-63,3 dan residu karbon 0,23-0,59 %berat/berat.


Kata kunci: Minyak kemiri sunan (Reutealis trisperma Oil), yield biodiesel, KOH.
