Abstract


Preparasi katalis padat K2O/C telah berhasil disiapkan dengan mengimpregnasi K2CO3 pada permukaan karbon aktif sekam padi selama 6 jam. Campuran tersebut dikalsinasi pada suhu 300 oC selama 3 jam hingga terbentuk K2O/C. Tujuan penelitian ini adalah untuk menginvestigasi kinerja katalis K2O/C dalam proses  transesterifikasi minyak biji kemiri sunan menjadi biodiesel. Karbon sekam padi (C) dipersiapkan dengan proses pirolisis sekam padi, dilanjutkan dengan proses aktivasi untuk mendapatkan karbon sebagai penyangga berpori. Katalis K2O/C  dikarakterisasi dengan Scanning Electron Microscopy (SEM) dan Energy-Dispersive X-ray (EDX). Hasil analisa EDX menunjukkan bahwa komposisi katalis didominasi oleh karbon (C) dan kalium (K). Fasa aktif K2O terdistribusi pada permukaan karbon aktif secara merata. Katalis K2O/C yang dihasilkan digunakan dalam reaksi transesterifikasi minyak kemiri sunan menggunakan reaktor batch. Yield biodiesel tertinggi dicapai hingga 98,68% ketika menggunakan katalis 4%, loading K2CO3  pada karbon aktif 0,5% berat, waktu  reaksi 90 menit, serta rasio molar metanol terhadap minyak 8:1. Katalis K2O/C sangat berpotensi untuk dikembangkan selanjutnya sebagai salah satu katalis padat untuk mengkonversi minyak nabati menjadi biodiesel.
