Abstract

Tobuuha Village, Puuwatu District, Kendari City was previously a green open area which was naturally used for water absorption. However, this area has now changed its function to become a densely populated residential area, resulting in a significant reduction in water absorption. As a result, when it rains, surface flow becomes greater and causes puddles downstream. The aim of this research is to model the Tobuuha retention pond using the SWMM application for environmental changes that occur. Primary data collection was carried out by observing existing conditions and measuring the dimensions of channels and ponds around the retention pond. Meanwhile, secondary data was obtained from related agencies. The results of the research show that the flood discharge that will enter the retention pond is Q5 = 0.559 m3/second with the volume of water that enters and must be accommodated in the retention pond of 4577.0934 m3, while the existing capacity of the retention pond is 6978.44 m3, so it is considered still able to reduce flooding downstream of the pond. Therefore, the city government's plan to expand and increase the depth of the pool is not necessary because it will reduce the open space around the pool. Handling potential flooding and inundation around the location can be done by adjusting the sliding door openings and modifying several channels, namely channels J51-J52, M62-M63, N71-N106, and U97-U101. The SWMM simulation results for the proposed solution show that the retention pond is effective enough to prevent flooding in the surrounding area

Abstract

Currently, the Bumi Mas BTN Magaga housing only has a septic tank in each house and a drainage channel for housing liquid waste. Waste, which mainly comes from kitchen and bathroom activities, is directly discharged into the drainage and forwarded to the nearest river without any wastewater treatment. If this continues, it will pollute the nearby river water. So that, the purpose of this research is how to design domestic wastewater treatment for Bumi Mas Housing BTN Magaga. The type of research used in this study is using quantitative research, with data collection methods namely observation, interviews, and literature study. Waste water treatment plant (WWTP) planning for Bumi Mas Housing BTN Magaga with a land requirement of 56.15 m2 wide (21.2 m long × 10.2 m wide) and a waste discharge of 2.8 m³/hour using an up flow biofilter system consisting of a collection tank with dimensions of 2.4 × 1.2 × 1 m tub volume 2.8 m3 and residence time of 1 hour, fat separator tank with dimensions of 2.4 m × 1.2 m × 1 m tub volume 8.4 m3 residence time 1 hour, equalization tank 3.4 m × 1.7 m × 1 m and a tank volume of 5.6 m3 with a residence time of 2 hours, a septic tank 6 m × 3 m × 4 m and a tub volume of 66 m3 with a residence time of 6 hours, a biofilter 6 m × 3 m × 2 m and a tub volume of 33.6 m3 with a residence time of 12 hours, and a final settling tank with dimensions of 4.20 m × 2.10 m × 1 m with a volume of 8.4 m3 with a residence time of 4 hours.
