Abstract

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%.

Abstract

This study was conducted at the Village of Delodbrawah, Jembrana Regency, Bali. It was aimed to know the managementpattern available at the Village of Delodbrawah, the effect of maintenance to the water quality of shrimp pond and river, vegetationcondition and river biota. The study was conducted for approximately 3 months in each pond starting from January up to May 2007.Shrimp ponds found in the Village of Delodbrawah use intensive and semi intensive management with open system where thechange its water maximaly from well and river. Semi intensive pattern used vitamin C as a mixture of food and the intensive one usedgarlic (Allium sativum L) as antibiotic. The use of natural antibiotics can increase the age of the shrimps up to 96 days before it washarvested. While the one using other probiotics, the age of the shrimps was 88 – 90 days shorter after it was harvested.The data of water quality showed that pond 1 that used intensive system had more stable water quality parameter and supportthe culture compared with other blocks. At the end of the culture of PO4 and NO2 tends to increase blooming plankton such asChlorella sp, Oscillatoria sp, Cyclotella sp. But it did not affect the quality of river water which was still under the threshold ofstandard quality of water class III Government Regulation of the Republic of Indonesia Number 82 of 2001 concerning theManagement of Water Quality and Water Pollution Control.Vegetation around the shrimp ponds were dominated by Nipah (Nypa fruticans Wurm) in the location nearing the river estuary.From the production data pond 1 had the best production, related to the nipah functioning as bioremediator of surrounding waters.The other location is near palawija plants. The most prominent river biota is kijing (Bivalvia) which looked bigger and many innumbers in the location where there are two disposal channels, pond disposal and agricultural channel that transports higher organicsubstance to be disposed to the river. Affectiveness of the intensive pond management optimally produces the oldest age of 96 days, the harvest of 3,964 – 4,271kg/1500 m2, Survival Rate (SR) of 98% and Feed Convertion Ratio (FCR) of 1,32

Abstract

Oily waste can pollute environment. One of the method used to process the oily waste is aerationmethod. This researce is carried out by taking oily waste PT. Indonesia Power Business Unit Electric PowerStation Bali at Pasanggaran Denpasar, aimed at increase quality of the waste.The sampel used is waste of PT. Indonesia Power Electric Power Station Business Unit of Bali. Thesampel is intercepted and retained in a retaining box, and 11,12 litters are then taken to be put intotreatment tank. Aeration treatment duration given varies, such as 12 hours, 24 hours, 48 hours, and 72 hoursfor the sampel with air flow speed of 0,6m/s. The treatment is also done with adding sampel with mud of 1%of the whole sampel volume. The relation between Aerating duration with oil contents, oil layer, BOD value,COD value, TDS value and TSS value will be analyzed with simple correlation and descriptive analysis.Aeration treatment can reduce the contents of oil in waste and separate oil accumulated in the waterso that the oil can be depressed up. Aeration treatment can also lower BOD value, COD value, TDS valueand TSS value because giving oxygen in to waste will meet the needs of oxygen of disentanglingmicroorganism in the waste water and the needs of oxygen for oxidation of chemicals in the waste.Therefore, aeration treatment can increase quality of the waste.

Abstract

Waste is one source of greenhouse gas emissions (GHG) that has methane gas form which caused an early multi-dimensional, massive and complex problems. The rapid increase of garbage volume entering landfill, annually result a high garbage dumps in the Suwung Landfill area. It should have been considered a handing solution for example by converting the methane gas content in the waste into a useful value added product. The objective of this research is determining the amount of electrical energy that can be produced through methane gas emission at Suwung Landfill. The characteristic and composition of waste could give effect to the formation of methane emissions. The research on the composition and characteristic of waste were done by sorting 1 m3 of garbage sample from new garbage entering landfill. Garbage is divided based on the source of DLHK waste, market waste, and private waste. The volume of waste that went to Suwung Landfill in 2016 calculated 1.296.438 m3 which was dominated by organic waste (78,1%). The density of the waste that went into Suwung Landfill, based on the research's results, amounted to 135,09 kg / m3, there fore could be assumed that the weight of waste that went to Suwung Landfill in 2016 was 175.135,81 tons. Based on these data, the number of 136.785,13 tons of waste, which was organic waste, could increase the concentration of greenhouse gases in the atmosphere if this situation does not manage properly. Gravimeter method is using for measures the dry matter content value of waste. From the measurement, the results obtained the waste components that have the highest dry matter content is from rubber and leather garbage (76,52%) while the lowest dry matter is food waste (19,13%). By using calculations based on IPCC 2006, it was found that the amount of methane emissions could be generated by the waste at the Suwung Landfill in 2016, amounted to 3.535,06 tons. Based on the energy equivalence table, the electrical power that is generated from the potential methane emissions at the Suwung Landfill is 6,66 MW. Keywords: waste composition, waste characteristics, methane emissions, ipcc2006, electrical power.

Abstract

Telagawaja Sub-Watershed is upper part watershed of Unda Watershed. As upper watershed, Telagawaja sub watershed has functions as conservation area, water catchment area, and managed in order to keep sub watershed environment not degradated. This research objectives are to identify the characteristics of the land, the function of the area, and the erosion potential rate (TBE), as well as land management recommendations on Telagawaja Sub-Watershed. The identification of land is conducted by analyzing the characteristics of thematic maps in study area. The directives of classification land function is determined by the Minister of Agriculture Number.837/Kpts/Um/ 11/1980 and Number: 683/Kpts/Um/8/1981. The prediction of actual erosion is calculated by USLE formula for the agriculture area, while non-agricultural land use is applied Snyder formula (1980) in Asdak (2010). Erosion class and erosion rate (TBE) are determined based on the Director General of Reforestation and Land Rehabilitation Department of Forestry Number.041/Kpts/V/1998. Determination for the amount of erosion is still can be allowed using the method of Thompson (1957) in Arsyad (2010) which based on soil properties attached to Telagawaja sub watershed. The research shows that Telagawaja Sub-Watershed characteristic is an area which is susceptible to erosion.The analysis shows that the direction of the area function Telagawaja sub-watershed consists of an area of 7337.28 Ha of protection forest (66.01%), and the function of a buffer area 3.778.31 Ha (33.99%). The result of the study on Telagawaja sub-watershed erosion is 2777.07 tonnes ha-1year-1. Erosion class and erosion rate of Telagawaja Sub-Watershed vary from very light to very severe. Erosion class and erosion rate (TBE) with category severe to very severe consist an area of 2.071,97 ha (18,64 %) from total sub-watershed area. Land use planning implemented by applying alternative measures of soil and water conservation can reduce the rate of erosion of 2777.07 tonnes ha-1year-1 to 611.00 tonnes ha-1year-1 or less 2166.07 tonnes ha- 1year-1.
