Berdasarkan unjuk kerja katalis CaOSiO 2 yang dibuat untuk reaksi transesterifikasi minyak kelapa, maka penelitian selanjutnya disarankan untuk meneliti menggunakan katalis yang sama untuk transesterifikasi minyak nabati lainnya menjadi biodiesel. Di samping itu, perlu juga diteliti unjuk kerja katalis untuk transesterifikasi asam lemak spesifik yang terkandung dalam minyak kelapa. DAFTAR PUSTAKA Agung, M. G. F., M. R. Hanafie Sy., dan P.
