Abstract

Water cleanliness plays an important role as a parameter in observing the quality of water that is suitable for consumption for every human life. This is certainly reflected in the health of a healthier life, but so far it is still low in the water quality that is suitable for community use. This study presents a simple technology to design water filtration using an up-flow system (bottom to up) and finds the effectiveness of the filtration media in reducing the content of iron (Fe) and manganese (Mn) metals in groundwater. Water samples were taken from Bukit Fadiah Asri Housing, Kendari City, and tested using three variations of media composition consisting of fiber, gravel, activated charcoal, black sand, and silica which flowed from bottom to top by gravity. Based on these results indicate that type B media material consisting of gravel, palm fiber, black sand, activated charcoal, silica, and palm fiber with a media thickness of 10 cm has a very good level of effectiveness which can reduce the metal content of Fe by 75% and Mn by 66%. This simple and inexpensive filtration media can be applied to the community to neutralize groundwater turbidity and reduce Fe and Mn metal content because it is used as an adsorption medium for heavy metals in water.

Abstract

This study aims to design an effective drainage system to reduce waterlogging in the residential area of Barong Tongkok District, Kutai Barat Regency. The analysis combines rainfall data, land-use conditions, and physical characteristics of the study area. Design rainfall was calculated using the Log Pearson Type III distribution, rainfall intensity using the Mononobe method, and peak discharge using the Rational Method. The results show that the design flood discharge for a 10-year return period is 1.203 m³/s. Using Manning’s equation, a trapezoidal channel with a 0.65 m bottom width, 1.00 m depth, and 0.27 side slope has a flow capacity of 1.33 m³/s. This indicates that the planned drainage channel can accommodate the design discharge and is suitable for implementation in the study area. The proposed design is expected to improve drainage performance and reduce flood risks in Barong Tongkok District.

Abstract

Through Indonesian Goverment Regulation Number 22 of 2021 explains that the implementation of environmental protection and management, which is meant by air pollution incidents, is the entry or introduction of substances, energy and other components into the ambient air by human activities, so that the air quality drops to a certain level which causes the ambient air unable to fulfill its function.” Decreased quality of ambient air because pollution in ambient air has exceeded a certain threshold, thereby endangering living things and the environment. Taking samples of Sulfur Dioxide (SO2) gas using an impinger, laboratory testing results of sulfur dioxide (SO2) samples at four environmental baselines for alternative road construction Matabondu - Lalingato obtained SO2 level results, the first point was 16.80 µg/m3, the second point was 18.50 µg/m3, the third point was 18.50 µg/m3, and the fourth point was 14.90 µg/m3 at the four research locations. The SO2 level is the first point 16.80 µg/m3, the second point 18.50 µg/m3, the third point 18.50 µg/m3, and the fourth point 14.90 µg/m3. So it can be concluded that sulfur dioxide (SO2) pollution is still below the quality standard limit set by the Government of the Republic of Indonesia Regulation Number 22 of 2021 on Implementation of Environmental Protection and Management.

Abstract

Flood discharge design analysis is an important step in water resources planning and management, especially for flood risk mitigation in areas prone to inundation. This study aims to calculate the flood discharge design in the Talangsari River Basin using appropriate hydrological methods, namely the Log Person Type III distribution method, the Rational Method and the Manning Formula Method. The annual maximum rainfall data from the Web. BPS Samarinda City for 11 years has been used as the basis for analysis. The analysis process involves calculating rainfall intensity, watershed area, and runoff coefficient to obtain the flood discharge design with various periods of years 2, 5, 10, 25, 50, and 100. The results of the analysis show that the flood discharge increases as the period increases, with a maximum discharge of 9,429 m³/s for the  year period. These results provide an important reference for flood control infrastructure planning, such as river widening, reducing riverbed sediment and strengthening riverbanks using crushed stone foundations, to minimize the impact of losses due to flooding in the future.
