Aplikasi Biosurfaktan Dari Daun Sengon (Albizia Falcataria) Dan Kulit Buah Pepaya (Carica Papaya L.) Sebagai Detergen Ramah Lingkungan

Abstract

The problem of using detergent that contain synthetic surfactants can pollute the environment, so we need an environmentally friendly surfactant as sengon leaf and papaya peel. This research aims to obtain the optimum composition and operating conditions. Biosurfactant produced was carried out by adding HCl (0.2; 0.4; 0.6; 0.8 and 1.0%) and extract concentration (v/v) (15, 30, and 45%). Analysis of biosurfactant consists of pH, foam height, and protease enzyme activity. Production of detergent is done with variations in temperature (30, 50, 70 and 90ºC) and stirring speed (200, 250, 300, and 350 rpm). Detergent produced was analyzed for physicochemical properties and level of pollution. The optimum result of biosurfactant obtained at variation extract concentration of 45% and HCl 0.6% with pH 2, foam height 18-20 mm, and protease enzyme activity 0.3416 U/mL. The optimum temperature and stirring speed in making detergent are 50ºC and 250 rpm. The physicochemical properties of detergent produced is accordance of SNI 06-4075-1996 with pH 11, density 1.0417 g/mL, and detergent power 3.65 NTU, while the results of testing the level of pollution of detergent produced hasfulfilled with the South Sumatra Governor's Regulations No. 8 in 2012.
