Abstract

Biogas is generated from biological process of organic material by bacterial engaged. Biogas can be derived from manure, municipal waste, agricultural waste and other biomass resources. In addition to the use of cow manure as raw material for biogas production, it can also be derived from biomass containing cellulose which one is water hyacinth as an organic material that contains quite large cellulose. The abundance of water hyacinth found in Rawapening causing several negative impacts. The purpose of this study is to observe  temperature and pH on the biogas production generated from water hyacinth of Rawapening and cow manure. Biogas production process begins by chopping the leaves and stems of water hyacinth, and then mixed with cow manure and water. The results of substrate variation of water hyacinth, cow manure and water reaches optimally at 40:80:480 respectively, which produce the highest point of  biogas amounted 176.33 ml on the day 20 in 1L sized digester, the temperature of the biogas production is at 32°C.  At the initial fermentation, digester temperature of 30°C has increased over the course of the fermentation process, a peak at day 20 and then decreased to 27°C at the end of fermentation. There is a decrease in pH starting from initial fermentation at pH 6-7 and then the pH began to decline until the end of fermentation as amount of pH 5.Doi: http://dx.doi.org/10.12777/wastech.1.1.22-25Citation:  Nurfitri Astuti, N., Tri Retnaningsih Soeprobowati, T.R., and  Budiyono. 2013.

Abstract

Abstrack - The plastic industries has increased by 7-8% per year, it will cause a negative impact for the environment. The wastewater of plastic industrial contain many pollutants such as hazardous substances bensen, formaldehyde and heavy metals (Cd, Cu, Cr and Pb). Heavy metals Cu is the most dangerous heavy metals since Cu can inhibit enzyme systems, remediation are needed to reduce the pollutants in the environment. One effective way is by using Chlorella pyrenoidosa H.Chick as phycoremediation agent. This study aims to assess the percentage of population growth and decline of heavy metals Cu after inoculation with C. pyrenoidosa H.Chick. The method used is to cultivate C. pyrenoidosa H.Chick in plastic wastewater for 8 days and observed a decrease of percentage heavy metal Cu and population growh of C.pyrenoidosa H.Chick. Environmental factors such as temperature, salinity, pH, light intensity is maintained in order to remain stable. The data obtained with T test. After 8 days of the study turned out that C. pyrenoidosa H.Chick able to reduce Cu of 0.435 mg / l to 0.24 mg / l within 8 days and decrease percentage is 44.83%, thus meeting the criteria of the quality standard of waste according to the PP. 82 of 2001 in the amount of 0.2 ppm and safe for environment. Keywords: Chlorella pyrenoidosa, phycoremediation, water, plastic, copper.
