Abstract

Fenol is a hazardous substance that can pollute the environment. Traditional herb Industry is one of industries produces liquid waste with high pollution level, the fenol content more than 9 mg/L.  Biological treatment  with anaerobic activated sludge method is one effective way of processing waste.This research was aimed to study the effect of MLSS variable and fenol load, the efficiency of fenol decrease in anaerobic waste processing system. The experiment is conducted by synthetic herbs waste with COD content of ± 3610 mg/L, retention time of 6 hours at a temperature of 30oC, atmospheric pressure in anaerobic baffle reactor continuously. The reactor volume is 60 L, the MLSS content of 3000; 4000; 5000 mg/L,  fenol load at 0, 3, 6; 9; 12 mg/L. Result of research show that active sludge of mixture breeding  from cage manure effective for the processing of waste with the low rate fenol (less than 6 mg/L) with the efficiency of degradation fenol 89,7-99,87% but less be effective at high burden fenol (more than 6 mg/L) with the efficiency of degradation fenol equal to 18-52%. The results obtained compared well with other reduction process.

Abstract

This research was to utilize solid waste of durian (durian skin) into economically valuable products. The purpose of this research was to obtain a decorative paper or art paper which can be used as a wide range of creative products such as photo frames, tissue boxes, pencil boxes and others. The research was carried out by destroying the skin of durian and other materials to form slurry and then molded and dried. Assessment of art paper quality was based on the beauty of its performance because it was display the fibers on the surface of the paper. It has been carried out analysis of gramatur, tear resistance, moisture content and ash content of the paper produced by durian skin. Paper with gramatur value, moisture content, low ash content and high tear resistance was the good quality paper. For gramatur and water content testing, a paper which was given a red ocher dye (D) is a paper that has the lowest value of gramatur and water content, each of 0.0212 g/cm2 and 7.77%. While the ash content and tear resistance testing, colored paper with mangosteen peel 17% (E) has a low ash content (0.056%) and high tear resistance (104 times fold).
