The Design Of An Experimental Anaerobic Digestor For Organic Waste Processing

Blockage of septic tanks is one of the problems in the community related to the discharge of toilet waste produced. The use of synthetic toilet cleaners that are not environmentally friendly is one of the factors that can inhibit the process of decomposing organic waste. The existence of microbial killer ingredients in toilet cleaning materials that come into the septic tank will actually inhibit the growth of essential microbes that play a role in the perfection of the decomposition process. Lack of understanding of the community related to microbial processes in the processing of toilet waste is one of the factors inability of the community to overcome these problems. This community service aims to disseminate information related to the processing of organic waste, the role of microbes in the processing of toilet waste, how to make microbial formulas that play a role in the processing of toilet waste, as well as efforts to increase the creativity of the community to process their own waste to improve environmental sanitation and improve community welfare. The results of the training showed that the average pretest and post test scores of the cadres of Tenggilis Surabaya village experienced a significant increase in value with a mean value of 37.78 (pretest) to 62.22 (post-test). Toilet waste processing cadres have been able to make biotoilet products that can be used to process limbat toilets in their homes. The informationand insights they receive can be passed on to the community from each cadre.AbstrakPenyumbatan septic tank merupakan salah satu permasalahan di masyarakat terkait dengan buangan limbah toilet yang dihasilkan. Penggunaan pembersih toilet yang berbahan sintetik yang tidak ramah lingkungan merupakan salah satu faktor yang dapat menghambat proses penguraian limbah organik. Keberadaan bahan pembunuh mikroba dalam bahan-bahan pembersih toilet yang ikut masuk ke dalam septik tank justru akan menghambat pertumbuhan mikroba esensial yang berperan dalam kesempurnaan proses dekomposisi. Kurangnya pemahaman masyarakat terkait dengan proses mikroba dalam pengolahan limbah toilet merupakan salah satu faktor ketidakmampuan masyarakat dalam mengatasi permasalahan tersebut. Pengabdian masyarakat ini bertujuanuntuk mensosialisasikan informasi terkait proses pengolahan limbah organik, peran mikroba dalam pengolahan limbah toilet, cara membuat formula mikroba yang berperan dalam pengolahan limbah toilet, serta upaya meningkatkan kreativitas masyarakat untuk mengolah limbahnya sendiri guna meningkatkan sanitasi lingkungan dan meningkatkan kesejahteraan masyarakat. Hasil pelatihan menunjukkan bahwa rerata nilai pretest dan post test kader kelurahan Tenggilis Surabaya mengalami peningkatan nilai yang cukup signifi kan dengan rerata nilai dari 37,78 (pretest) menjadi 62,22 (post test). Kader pengolahan limbah toilet telah mampu membuat produk biotoilet yang dapat dimanfaatkan untuk mengolah limbat toilet di rumah masing-masing. Informasi dan wawasan yang mereka terima dapat di teruskan kepada komunitas asal masing-masing kader.

Pre Treatment

High percentage of organic waste in urban areas makes composting as good alternative in waste processing. However, composting has not been effectively used and the result is not optimal. Previous studies found compost can be used as biocover media to reduce methane emission landfill. The objective of the study is to identify the characteristic of produced at temporary waste unit Depok, West Java and the effect of compaction toward the amount of methane removal in the landfill. Before applied as biocover media, compost was characterized followed by maturation process. Study on methane removal efficiency was conducted as batches in four reactors for 35 days with compaction rate varying from 750, 800, 850 dan 900 kg/m3. Composting media used in the research had 80 cm thickness with artificial gas consisting of 50% CH4 dan 50% CO2. Initially, compost did not meet criteria as mature compost based on SNI 19-7030-2004, and as media biocover hence a pre-treatment was needed to improve the quality compost to meet the requirements. Compaction rate of 900 kg/m3has highest elimination capacity of methane i.e. 98,31%±3,6% and 13,98±4,32 g/m3/hour.

EFFECT OF NUMBER OF METHANOBACTERIUM AND FERMENTATION DURATION TO METHANE (CH4) GAS PROPORTION IN ORGANIC WASTE PROCESSING IN SUWUNG TPA DENPASARA research has been conducted to find out the effect to the amount of methanobacterium bacteria and fermentation duration toward proportion of methana (CH4) at organic waste processing at TPA Suwung Denpasar. Methana gas produced from this organic waste will be processed become fuel of electric generation. From this study will be expected to get all methana gas that contained at the waste so that there is no methana gas loss to the atmosphere. This study was conducted by using 4 treatments that are without bacteria (B0), bacteria with number of population 106 CFU/ml (B1), bacteria with population of 107 CFU/ml (B2), and bacteria with population of 108 CFU/ml (B3). Each treatment conducted thrice (3) repeat. The four treatments conducted measurement of gas variable after fermentation during 0 week, 3 weeks, 5 weeks, 7 weeks and 9 weeks by uisng gas analyzer GA 2000 Geotech. Data from study result then analyzed by using complicated factorial design (RAL). From ANOVA analysis shows there was significant bacteria number and fermentation duration toward proportion or procentage of methana gas resulted. The longer fermentation time takes place, the bigger the proportion of the methane gas produced. However, the greater number of the bacteria population does not always produce bigger proportion of methane gas To find out the combination which could give best effect the researcher used Duncan test. The result of analysis from Duncan shows that combination at the ninth weeks by number of bacteria 107 CFU/ml giving best result that was percentage of methana gas is 55,10%.
