Abstract

Predictions for ten years of methane gas emissions in research are conducted on wastewater. To predict the emissions of methane gas ten years first calculated the level of methane gas emissions. Then made predictions to know the emissions of methane gas produced by domestic wastewater for the last ten years. This domestic wastewater from rusunawa. The calculation of methane gas emissions is carried out with reference to the method developed by IPCC 2006. Based on calculations, household wastewater generates methane gas emissions in 2007 of 5648.75 kgCH4 / year or 8610.91 m3 / year and continues to increase each year. The methane emission prediction result yields the equation y = 1538x2 + 5836x + 16610 to predict methane gas emissions over the next ten years. While the conversion of electrical energy in 2007 amounted to 770.90 kWh and increased every year along with the increase in methane gas emissions. The prediction result of electrical energy yields the equation y = 137,7x2 + 522x + 1487 to predict electric energy ten years ahead.

In this study, samples will be taken from 6 Communal WWTP locations in the City of Malang. Based on the review of Communal IPAL by DEWATS, the majority of IPAL Communal is not monitored, so it is necessary to evaluate evaluation on the ability and willingness of the community to care for WWTPs Communal with operating costs according to SOP. Based on the results of the evaluation of the financial aspect, the willingness of residents to pay fees between 2000 rupiahs to 5000 rupiahs and the ability of residents to pay at the Tlogomas Communal IPAL is Rp. 11,150, Oro - Oro Dowo Rp. 7,125, Jodipan Rp. 8,900, Kota Lama Rp. 8,750, Mergososo Rp. 6,150, and Gadang Rp. 8,900.

Abstract

Water as the basis of life is very important for human life. Population growth is increasing the need for potable water in communities, especially in southern Badung County. The source of drinking water demand is managed by PDAM Tirta Mangutama Badung Regency. The problem is that in the two districts, all the communities that are not part of the PDAM do not have drinking water. Considering this, it is necessary to identify the needs of people who need water in the community, to have clean water and sanitation facilities for houses and hotels in Kuta and South Kuta in the next five years. of the lake estuary IPA. This study was conducted by evaluating the water treatment process to obtain clean water, analyzing the clean water requirements and analyzing the operating costs for the treatment of clean water. The analysis shows that household and hotel water needs will increase by ±10% by 2025. The clean water capacity of the Estuary DAM IPA is 500 liters/second, which is still sufficient for the needs drinking water for homes and hotels in Kuta. South Kuta District. Water treatment operating cost requirements (chemical costs and power plant costs) increased by ±7% by 2025
