EFEKTIVITAS SENYAWA ANTIOKSIDAN JAHE DALAM MENGHAMBAT OKSIDASI MINYAK JELANTAH
The repeated use of cooking oil during frying causes oxidation and thermal degradation that reduce oil quality and produce harmful compounds. The utilization of natural antioxidants has become an alternative approach to improve the quality of waste cooking oil. Ginger (Zingiber officinale) contains phenolic compounds with strong antioxidant activity

Modifikasi Biodiesel Melalui Reaksi Oksidasi Menggunakan Gelombang Ultrasonik
Biodiesel is an alternative energy fuel that is sustainable and environmentally safe. However, biodiesel has a higher cloud point than fuel diesel because it contains several saturated fatty acids such as oleic acid, linoleic and linolenic acid so that biodiesel tend to solidify at a temperature higher than the freezing point of diesel. This study aims
