Abstract

Acid deposition is a phenomenon of air pollution that is mostly associated with energy activities that emit acidic pollutant compounds into the atmosphere. Acid deposition is one of the effects of air pollution. Observation of air quality in Sorong City is needed to determine the level of air pollution that occurs due to natural factors and anthropogenic activities. Observation of acid deposition in Sorong City was carried out with two parameters, namely wet deposition and dry deposition. Observation of wet deposition using chemical measurements of rainwater in the form of pH, Conductivity, and Mineral Ion Concentration. Observation of dry deposition using SPM Particulate and Passive Gas (SO2 and NO2) parameters. The results show that the level of acidity (pH) of rainwater in Sorong City during 2022 is included in pH category of acidic rainwater that tends to be neutral. Meanwhile, the result of conductivity value is 2.2 – 50.9 µS/cm. The chemical composition in rainwater in Sorong City is dominated by chloride ions, sulfate ions, potassium ions and sodium ions, where the number of anions accounts for 59% of the total ions present in rainwater, and cations contribute 41%. During January to December 2022, daily SPM concentrations were in the range of 8.63 - 96.24 µg/m3. Based on the value of the quality standard, both daily and yearly, SPM value is still far below the applicable threshold value. The results of SO2 and NO2 measurements in Sorong City also show that concentration values are still below the air quality standard values.

Abstract

Sorong City is a developing city, which in recent years has been intensively developing facilities and infrastructure in all fields. Some of the developments that are intensively carried out are road construction and housing settlement development. Sorong City, especially the Harapan Indah Complex area, is one of the developing areas that is prone to flooding and local inundation during the rainy season. The purpose of this study is to determine the condition of the drainage system in Harapan Indah in accommodating the maximum rain discharge for a certain period of time. The research method used is to process data obtained from the field and then process it using EPA-SWMM software to simulate drainage flow due to surface runoff that occurs. From the results of simulations using EPA-SWMM software, the condition of the drainage system in the Harapan Indah complex area is still often overflowing, obtained from the results of the analysis of regional channels on Jalan Cendrawasih most overflowing in the return period of 2 years, 5 years & 10 years. On Jalan Cendrawasih there are overflowing channels, namely 18 channels with a 2-year return period calculation, 24 channels with a 5-year return period calculation and 25 channels with a 10-year return period calculation.

Abstract

The Sorong Regency Government, through related agencies, is building, operating and maintaining a clean water distribution network in Sorong Regency, considering that population growth continues to increase and limited raw water sources have caused the clean water distribution system in Aimas District to experience several problems so that its operation cannot run optimally. This research aims to evaluate the performance of clean water distribution in the Aimas District, Sorong Regency in meeting the clean water needs of the Aimas District community. The method used is to collect primary and secondary data and then analyze it using Epanet 2.0 software to simulate the condition of the distribution network system in the research area. Based on the results of calculations, the raw water discharge in the research area is smaller than the customer's water discharge, the delivery time for clean water does not run consistently, serving the water needs of areas outside the Aimas District, so the water needs of the people in the Aimas District cannot be fully met. Simulation results using Epanet 2.0 software show that unstable flow velocity causes a decrease in flow velocity in the clean water distribution network system in Aimas District.

Abstract

This research aimed to analyze the quality of borewell water widely utilized by the community on Jalan Pendidikan KM 8, Malaingkedi, Sorong Manoi District, Sorong City, West Papua. Water samples were collected at three different times, namely 09.00, 14.00, and 17.00. The parameters tested included physical parameters such as color, odor, TDS (Total Dissolved Solids), conductivity, salinity and chemical parameters such as pH. The results showed that in general, the quality of the borewell water still met the quality standards for clean water according to the Indonesian Ministry of Health Regulation No. 32 of 2017. The average values were 315.67 μS/cm for conductivity, 207 ppm for TDS, 157 ppm for salinity, and 8.47 for pH. There were variations in the values for each tested parameter, but they were still within the permitted range. However, some parameters such as slightly turbid water color and pH values slightly exceeding the ideal range were observed. Regular water quality monitoring and pollution control efforts are essential to ensure the availability of safe clean water for the community.
