Abstract
Padatan CaO telah berhasil dipreparasi dengan kalsinasi kulit telur ayam pada suhu 1000 ºC. Hasil karaterisasi dengan XRD dan SEM menunjukkan bahwa CaO yang dihasilkan memiliki pola difraktogram serta morfologi yang sama dengan CaO standar. Padatan CaO hasil preparasi tersebut ditanamkan pada permukaan abu layang dengan metode impregnasi, sehingga diperoleh katalis CaO/abu layang dan CaO/abu layang leaching. Hasil karakterisasi dengan SEM dan FTIR menunjukkan bahwa CaO menempel pada permukaan abu layang, serta membentuk ikatan Si-O-Ca dengan silika dari abu layang. Hasil uji katalis pada reaksi transesterifikasi minyak nyamplung dengan metanol menunjukkan bahwa kadar FAME paling besar dicapai oleh katalis 75CFAL, diikuti oleh katalis 75CFA, 50CFAL, CaO, dan 50CFA. Katalis CaO dengan pendukung abu layang menunjukkan aktivitas lebih tinggi dari pada katalis CaO
