Pengujian Kualitas Biodiesel dari Minyak Kelapa Sawit Dengan Katalis Heterogen Abu Daun Kucai (Allium schoenoprasum): Parameter Berat Katalis, Rasio Mol Minyak Terhadap Metanol dan Waktu Reaksi

The Chives’s Plant (Allium schoenoprasum) came from the wild ancestors that is native of European and Asian. ash chive leaves contain considerable amount metal, enabling its usage as catalyst in making biodiesel. Based on Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX) characterization, leaf calcined at 600 ˚C contained 26.14% potassium oxide, 17.55 calcium 21.94% carbon, 22.05% phosphorus pentoxide. later on, used biodiesel palm oil. highest yield 94.42% was achieved reaction temperature 60 ˚C, 3% amount, ratio oil methanol 1:12, time 120 minutes. density, viscosity, moisture, total glycerol has met Standar Nasional Indonesia (SNI) 7182:2015. However, purity still haven’t standards, which methyl ester content 69.13% triglyceride 18.83%.
