Abstract

Indonesia has biodiversity of basic ingredients that canused for making traditional medicines. Bioactive compounds also used as a source of antiinflammatory, antioxidant, anticancer, and antibacterial. Telang Flower is the One of plants that contain antioxidants. The aims of study is to determine the extract of secondary metabolic compounds contained in telang flower and secondary metabolic compounds in inhibiting the effects of free radicals. The maceration used as extraction method. The telang flower extraction result shown that contained of flavonoid compounds, alkaloids, tannins, terpenoids and steroids. The resulting bioactive compounds may act as antioxidants.

Abstract

Rubber seed is a source of vegetable oil that can be used for biodiesel production, but its use is not optimal. Although rubber seeds contain a lot of oil, it is possible to process them into biodiesel and become a renewable energy source from vegetable oil. The aim of this research is to determine the maximum yield and the effect of temperature on the transesterification process. The results of the research show that temperature variations affect the properties of the obtained biodiesel, namely the maximum yield at a temperature of 60 ºC is 90%, the density value in accordance with SNI 7182:2015 at a temperature of 80 ºC is 853.5 kg/m3, the viscosity value in accordance with SNI 7182:2015 at a temperature of 60 ºC and 70 ºC with a value of 2.83 mm2/cSt and 2.19 mm2/cSt respectively. The GC-MS analysis was carried out on the best samples with density values according to SNI 7182:2015, namely samples with a temperature of 80ºC for 60 minutes and consisting of methyl ether linoleic acid with a surface area of 35.32% and oleic acid methyl ester with a surface area of 4.46%
