Abstract

Patchouli oil refinery in Gayo Lues Aceh Indonesia commonly used evaporation process in an old drums at high temperature which decreased the quality of oil produced. The research to enhance the quality of patchouli alcohol of Gayo Lues patchouli oil using Citrus hystrix absorber has been done.The juice from kaffir lime (1 – 10 % v/v) used as chelating agent, and the kaffir peels powder (2,5 - 7 gr) used as bio sorbent. The highest patchouli alcohol (P.A) both resulted at T=50 oC and 60 minutes heating. Kaffir bio sorbent at 7,5 gr usage, gave 40,37% P.A and Fe reduction of 77,67%; while kaffir lime juice at 4% v/v usage, gave P.A 39,90% and Fe reduction of 78,25%. Purified patchouli oil also characterized by its light yellow color, density and refractive index based on SNI.06-2385-2006. It’s concluded that kaffir peels bio sorbent purification has superior P.A quality than kaffir lime juice.

Abstract

The industrial wastewater load pollutant caused without treatment. This study uses a simple technology to reduce the levels of COD, BOD5, and Nitrite by using coffee husk to minimized waters pollution or environmental damage. Adsorbents are activated by HCl 0.1 N and carbonized with muffle furnance to enlarge the surface area of the sorbent and to absorb the contaminants in the effluent of tofu industry. Tofu wastes containing COD, BOD5 and Nitrite contacted with activated carbon with varying weight of 0.2, 0.3, 0.4 gr and different  stirring times 10, 20, 30, 40, 50, 60 minutes and 125 rpm stirring speed with biosorbent size 80-100 mesh. The stirring time 10-30 minutes with the average concentration absorbed for BOD5 180 mg/l, COD 650 mg/l  and NO2- 20 mg/l and increasing the mass of biosorbent can increase the concentrasion of adsorption. The  efficiency absorption of wastewater absorbs more BOD5 than COD and Nitrite with BOD5 absorption efficiency is 85.38%. Adsorption of BOD5, COD and Nitrite follows Langmuir’s isotherm equation with R2 value is 0,8104 for BOD5, 0,7121 for COD and 0,7467 for nitrite

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%
