EVALUASI UJI KUALITAS BIODIESEL DARI MINYAK JELANTAH MELALUI REAKSI TRANSESTERIFIKASI MENGGUNAKAN NANOKATALIS CaO/MgO
Isi Artikel Utama
Abstrak
Sumber bahan bakar utama di dunia saat ini masih didominasi oleh bahan bakar fosil. Salah satu sumber energi terbarukan yang dapat digunakan untuk mengatasi permasalahan ini adalah biodiesel. Di Indonesia, produksi minyak kelapa sawit meningkat sebesar 89,8 % dalam rentang waktu 2018-2022 sehingga meningkatkan limbah minyak jelantah yang berpotensi sebagai bahan baku biodiesel. Tujuan penelitian ini adalah mengevaluasi kualitas biodiesel yang telah dibuat. Metode pembuatan biodiesel dilakukan menggunakan reaksi transesterifikasi selama 90 menit pada suhu 500C menggunakan rasio metanol dan minyak jelantah sebesar 7:1 dan berat nanokatalis CaO/MgO 1% (b/b) dari minyak jelantah. Kualitas biodiesel dievaluasi menggunakan parameter yang meliputi densitas berdasarkan ASTM D1289, viskositas kinematik berdasarkan ASTM D445, angka asam berdasarkan ASTM D664, dan kadar air berdasarkan ASTM 6751. Hasil uji kualitas biodiesel dengan nanokatalis 0CaO/MgO, 20CaO/MgO, 30CaO/MgO, dan 40CaO/MgO menunjukkan telah memenuhi standar.
