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

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.

Abstract

ABSTRACT The ULM integrated laboratory is a building that aims to assist activities for research by lecturers and students. The ULM integrated laboratory requires a piping system to ensure the availability of clean water as well as for good waste water distribution. The availability of clean water is used for laboratory support activities for the entire academic community. The designed system consists of a ground reservoir, pump, roof tank, clean water pipe, waste water pipe, vent and fire hydrant pipe. Clean water pipe 65 mm main pipe 65 mm largest branch pipe, waste water pipe 100 mm main pipe 75 mm largest branch pipe, main vent pipe 75 mm branch pipe 75 mm. The determination of the dimensions of clean water pipes in the planning of this 2-storey building using the pipe pressure equivalent method is carried out by comparing the available equivalent tables, without taking into account the factors of friction and power loss due to bends, use of connecting devices and so on. The pipe design that will be carried out is a pipe system for clean water, waste water and vents. The BOQ that will be described includes the BOQ for the number of sanitary equipment, for the needs of clean water pipes, waste water pipes, vent pipes as well as pipe accessories, fire hydrants, pumps and water tanks. Based on the results of the BOQ description, an RAB analysis will be carried out for these tools and will also be calculated for worker wages.

Abstract

Population growth in the village of Anjir Serapat Tengah continues to increase, this has an effect on environmental sanitation. The daily activities carried out will require water as the main ingredient, therefore it will result in an increase in the amount of waste water from these activities. The planning for making this communal WWTP also requires consideration where the electricity supply sometimes does not work at all times, as well as the land where the unit will be placed is quite large. Water sources used are PDAM by 66%, dug wells 2%, shallow wells 21%. Most of the waste water produced at 05.00-10.00 is 62.80%. Appropriate processing for the treatment of wastewater produced by residents in the river basins in Anjir Serapat Tengah village, namely wastewater treatment using a septic tank bio filter Anaerobic Baffled Reactor (ABR) technology with a planned WWTP discharge of 152 m3/day Keyword: Wastewater, Anaerobic Baffled Reactor, Septic Tank.
