Pemanfaatan Abu Sekam Padi Untuk Pemurnian Bahan Baku Dan Produk Biodiesel Dari Minyak Jelantah

Abstract: Abu sekam padi (ASP) merupakan limbah pada proses pembakaran batu bata yang berpotensi sebagai adsorben karena memiliki kandungan silika yang tinggi. Penelitian ini bertujuan untuk mengetahui potensi abu sekam padi sebagai adosorben pada proses pembuatan biodiesel dari minyak jelantah. Abu sekam padi diaplikasikan dalam pemurnian minyak jelantah dan juga produk biodiesel. Penelitian ini dilakukan dengan beberapa tahap yaitu karakterisasi ASP, pemurnian minyak jelantah, pembuatan biodiesel melalui transesterifi… Show more

“…Free fatty acids are positive ions contained in oil, where the husk ash adsorbent has hydroxy groups which are able to attract them because they are negative ions [29]. Rice husk is an adsorbent containing amorphous silica which, when contacted at room temperature, is able to absorb natural FFA compounds, phospholipids, and also lutein in oil micelles [30]. Fatty acid levels affect taste, according to [2], high levels of FFA can cause the oil to taste bad when consumed and reduce the yield.…”
