Abstract

The air pollution problems have been progressively set attention to the world especially industrialcountries recently. These problems not only give affect at health like emphysema, bronchitis, and otherinhalation disease but also make plants and properties destruction causes very big loss. This research isconcerned with the risk level which is accepted by people who reside in roadside because most of airpollutants come from transportation facilities such as motor vehicle. The limitation of the research is airpollutants exposure such like NOx, and SOx which enter the body through respiration. This risk analysisresearch is broken down into four step as follow; hazard identification showing NO2, and SO2concentration in 15 sampling locations where the highest value of NO2 is 56,5 μg / m3 and SO2 is 28,87μg/m3. According to DIY Governor Regulation No. 153 Year 2002 about the value of ambient air qualitystandard, quality standard of NO2 is 400 μg / m3, and SO2 is 900 μg / m3. It can be concluded thatconcentration of NO2 and SO2 in 2005 within all sampling locations is still under of quality standard. Thestep of exposure assessment involves the exposed population including pedicab worker, park worker, andcloister merchant. From calculation, the intake range of NO2 enters the body is 0,0025-0,0075 mg/kg.dayand SO2 is 0,0008-0,0038 mg/kg.day. Third step is dose-response assessment to find out what will be facedby people if exposure of pollutants occurs in a certain dose. The last step is risk characterization, theresult of research is that risk value / Hazard Index (HI) less than 1 that still acceptable. It can besummarized that the ambient air quality of Jogjakarta especially NO2 and SO2 gas do not too adverse tohealth.

Abstract

Semarang City’s drinking water distribution system in the North Semarang uses an interconnectionnetwork system. This causes difficulty in optimizing the network distribution supply and controlling thewater leakage. Semarang City’s drinking water provider is planning to divide the area in to 25 zones. Thisstudy purpose to plan one of the zone areas, which is zone 1. The existing condition on zone 1 shows thatthe water source is from Siranda distribution reservoir. The water flows by the gravitation. The distributionpressure on the pipe network is not even. Pressure drop between 3 to 7 m water columns at the peakcondition on the end of the furthest point in the network. The strategy in planning the network is by cuttingthe interconnection pipe, providing new pipes, closing the existing valves, adding new valves for isolatedareas, adding primary water meter and sub zone water meter and moving the interconnection pipes. Then,the distribution system is analyzed using Epanet 2.0 program that can show the effort of the changes after.The system shows that there is no more pressure drop on the area. The pressures are between 11-16 meterwater column and the water flow in the pipes are more alike, between 0,3 to 3 m/s. The PDAM can observethe distribution and the water leak more easily by using this system.

Abstract

In 2017-2019, the Tanah Laut Regency, Banjar Regency, Banjarbaru City population was relatively high and continued to increase every year. The increase in the population reaches 1.39% to 2.92%. Along with population growth, the human need for clean water also increases, especially from groundwater. The study aims to assess the vulnerability of groundwater to contamination. The method used for the analysis of groundwater vulnerability to contamination is the DRASTIC method. It refers to seven parameters, namely groundwater depth (D), net recharge (R), aquifer media (A), soil layer (S), topography (T), impact to vadose zone (I) and hydraulic conductivity (C) by using geospatial analysis to calculate the DRASTIC Index/DI. From the results of geospatial analysis, there are three zones of groundwater vulnerability to contamination based on DI values, namely low vulnerability (95-106), medium vulnerability (106-146), and high vulnerability (146-186). The distribution of high zones dominates in the research area around of 75, 8%. The DRASTIC method requires a lot of data to provide an accurate analysis of groundwater vulnerability zone maps. This method has excellent accuracy and more effective in producing a map of the groundwater vulnerability zones to contamination.
