Modifikasi Minyak Sawit Sebagai Pensubstitusi Minyak Solar
Sari
Minyak sawit dapat digunakan sebagai bahan bakar diesel alternatif dengan perbaikan kualitasnya. Pada penelitian ini dimodifikasi dengan cara pencampuran menggunakan minyak solar. Hasil uji sifat fisika kimia terhadap minyak sawit dan setelah dicampur dengan minyak solar beberapa karakter yang semula tidak, menjadi memenuhi spesifikasi minyak solar 48. Pada variasi pencampuran minyak sawit 20% volume menunjukkan sifat fisika kimia masih dalam rentang spesifikasi minyak solar. Viskositas dan berat jenis tinggi dapat diatasi dengan modifikasi. Minyak sawit dengan viskositas semula 5,572 cSt menjadi 4,382 cSt, berat jenis yang semula 871 kg/m3 menjadi 851 kg/m3 dan indeks setana lebih tinggi dari 47,9 menjadi 54,9. Bahan bakar diesel hasil penelitian ini mempunyai nilai lebih dari biodiesel yang dicampur dengan minyak solar. Minyak sawit dan minyak solar langsung dicampur, tanpa harus diproses terlebih dahulu menjadi biodiesel. Minyak sawit sebagai sumber energi terbarukan dengan masing-masing karakter yang telah dibahas kiranya menjadi pilihan yang layak untuk mempertahankan ketahanan energi jangka panjang.
