Abstract

Coal stockpiling activities in the stockpile produce coal stockpile wastewater which contains pollutants so that it needs to be processed before being released into the environment so as not to cause pollution in accordance with the regulations in South Kalimantan Governor Regulation No. 36 of 2008 concerning Coal Wastewater Quality Standards. This study aims to analyze the results of the quality test of coal effluent after being treated by the electrocoagulation method in meeting environmental quality standards and to analyze the effect of the electrode distance used in the electrocoagulation method on the treatment of coal effluent. This research method is in the form of electrocoagulation, the wastewater treatment process using direct electricity and the electrode is an Aluminum (Al) plate with dimensions of 20 cm x 10 cm and a thickness of 0.5 mm. The parameters were Total Suspended Solid (TSS), pH, iron (Fe) and manganese (Mn) with variations in electrode distance of 1 cm, 2 cm, and 3 cm with a contact time of 90 minutes. The voltage used is 12 volts and the current is 10A. The results showed that the electrocoagulation process with an electrode distance of 1 cm was the most efficient in reducing pollutant levels, in the pH parameter the value increased from 5.36 to 7.23, in the TSS parameter the efficiency value reached 99.97% with a reduction in levels from 4305 mg. /L to 1.33 mg/L, on the iron (Fe) parameter the efficiency value reached 99.95% with a reduction in levels from 53 mg/L to 0.02 mg/L and on the manganese (Mn) parameter the efficiency value reached 99.85% with a reduction in levels from 20.32 mg/L to 0.031 mg/L. The results showed that each parameter after the electrocoagulation method was in accordance with environmental quality standards.

Abstract

ABSTRACT Management and control of an air pollution is needed for the impact of air pollution is not very severe. The cement industry is one of the industries that uses high temperature heating in the production process. Mass balance calculations are needed to see the amount of material entering and leaving a process, based on the law of conservation of mass, that is, the amount of mass that enters is equal to the amount of mass that leaves. One source of immovable emissions is the chimney. Evaluation of the chimney dimensions is also carried out so that it can be a reference in the optimal exhaust gas velocity. Things to consider in analyzing an air quality using an analysis of the pollutant dispersion model. An application that can be used to predict the distribution of pollutants is AERMOD. The total mass entering the Suspension Preheater is 748,682.78 kg/hour. with a total mass output of 157,506,6898 kg/hour and a total mass loss of 591,176.09 kg/hour; Based on calculations to plan the volume and dimensions of the chimney by taking into account the conditions around the source point, the height of the chimney is 72 meters and 65 meters. With exhaust gas velocity is 20 m/s and 21 m/s, respectively; Based on the distribution pattern with a period of 24 hours, it is known that the concentration of TSP, SO2, and NO2 in the air when the receiving point is at an altitude of 1.5 meters from the ground surface has a maximum concentration of TSP, SO2, and NO2 respectively of 8,323 g/ m3, 36,171 g/m3, and 38,307 g/m3. While the difference between the simulated and in the field is better with a chimney height of 72 meters in order to maximize emission distribution compared to a chimney height of 65 meters.

Abstract

Manarap Lama and Manarap Tengah villages are located in Kertak Hanyar subdistrict with the hghest population density. High population density can affect the amount and quality of domestic wastewater produced. Access to sanitation in this area for ownership of Permanent Healthy Latrine is 92.37%, Semi-Permanent Healthy Latrine is 6.54%, and open defecation behavior is 1.09%. Domestic wastewater comes from various household activities such as bathing, washing, and latrines. Greywater is directly discharged into the river and blackwater is channeled into the septic tank without regular draining which can blend with river water. Thus causing the water quality in this area to exceed the quality standards set by PERMEN LHK No. 68 of 2016. Domestic wastewater treatment systems that have not been implemented can also have a negative impact on the sanitation conditions in this area. The purpose of this study is to analyze the existing condition of the area and then make a planning for the domestic wastewater distribution system. The research method is based on primary and secondary data collection and data analysis. In planning the domestic wastewater distribution system, three alternative pipelines are planned. Based on the results of the selection, alternative B is obtained as the chosen alternative route which has a channel length of 10,751 m, a flow time of 5.71 hours, requires 97 manholes, and a pipe cost investment of Rp1.848.051.349 (One Billion Eight Hundred Forty Eight Million Fifty One Thousand Three Hundred Forty Nine Rupiah).

Abstract

Domestic wastewater in Plajau Indah Housing has not been appropriately managed. The gray water is discharged directly into the drainage without processing, and the black water is managed through septic tanks that are not up to standard. Further treatment is required after passing through the septic tank unit so that the effluent discharged does not contaminate groundwater. This final project aims to plan a domestic wastewater distribution and treatment system at Plajau Indah Housing with effluent quality referring to the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia number 68 of 2016 concerning domestic wastewater quality standards. This planning method includes licensing, literature study, primary data collection from direct field surveys, secondary data collection from relevant agencies, planning domestic wastewater distribution and treatment systems, designing domestic wastewater distribution and treatment units, and analyzing data results. The domestic wastewater distribution system uses a shallow sewerage system with centralized WWTP management (off-site) divided into 19 service blocks. The pipe diameters used in this design are 100 mm, 150 mm, and 200 mm. The average wastewater discharge in Plajau Indah Housing is 203.94 m3/day. The WWTP plans to use an aerobic-anaerobic combination, namely the Anaerobic Baffled Reactor with 5 compartments, 1 settling basin, and a modified trickling filter. The dimensions of the whole ABR tub are 30 m x 8 m x 2 m; the dimensions of the trickling filter from the results obtained are 3 m x 8 m x 2 m.
