Abstract

Daerah Aliran Sungai (DAS) Manggar Kecil adalah salah satu kawasan di Kota Balikpapan yang memiliki potensi banjir. Upaya pemerintah Kota Balikpapan dalam menangani masalah banjir di DAS tersebut melalui perencanaan pembangunan bendali. Dalam perencanaan bendali membutuhkan data debit banjir, maka perlu dilakukan pendekatan hidrograf. Selain itu, dalam perencanaan bendali dilakukan pengaplikasian pintu air dengan tipe sorong atau sluice gate. Terdapat 3 (tiga) tahapan dalam penelitian ini. Tahapan pertama yaitu menganalisis debit hidrologi menggunakan HSS Nakayasu secara analitik. Tahapan kedua adalah memodelkan bendali dan pintu air, dilanjut dengan menganalisis berdasarkan bukaan pintu air. Tahapan keempat adalah analisis rating curve yang digunakan untuk mengetahui elevasi muka air, elevasi jagaan dan tampungan pada bendali. Berdasarkan hasil analisis, diperoleh debit periode 100 tahun metode HSS Nakayasu sebesar 212,9 m3/detik. Oleh karena itu, debit yang dipakai untuk pemodelan bendali menggunakan debit hidrograf metode Nakayasu. Berdasarkan pemodelan bendali menggunakan HEC-RAS, diperoleh penurunan elevasi muka air berada pada elevasi 18,91 meter. Pada elevasi ini, tampungan bendali dapat menampung volume air sebesar 5.236,486 m³. Selain itu, bendali secara signifikan mampu mengurangi dan mereduksi volume debit banjir sebesar 195,2 m³/detik. Hal tersebut memberikan tambahan elevasi jagaan (freeboard) yang cukup besar, sehingga bendali tidak mengalami overtopping atau luapan air yang melewati batas mercu bendali.

Abstract

Drought frequently occurs in Trenggalek Regency, with Prambon Village being one of the affected areas. The prolonged droughts in Prambon Village cause the water sources to dry up. As the population increases, so does the water demand. This study used arithmetic methods to project the population size until 2032. To assess the availability of water, the study used the F.J. Mock method and direct testing. According to the F.J. Mock method, the water balance indicated a surplus, projecting that the available water supply would meet the villagers' needs through 2032. However, the water balance based on data from the PKPLH Department and direct testing shows a deficit, insufficient to meet the population's needs until 2032. To address this issue, the conservation of water resources is necessary, involving the construction of spring protections, tree planting, and rainwater harvesting to ensure that the water needs of Prambon Village residents are met. This research serves as a reference for clean water utilization in Trenggalek Regency.

Abstract

Malang City is the second city in East Java, facing an increased risk of flooding due to population growth, changes in land use, and reduced infiltration areas. Jalan Bareng Raya II is one of the affected locations, with flooding occurring on April 29, 2023 due to high rainfall intensity. This study aims to evaluate the condition of the existing drainage network in the area using quantitative descriptive methods, including data collection, analysis, and interpretation of results. The SWMM (Storm Water Management Model) application is used to simulate overflow channels. Primary data was obtained from direct observation, while secondary data came from the Malang City PUPR Service and BPS. The SWMM simulations show 11 channels overflowing, which can be reduced with a combination of infiltration wells and biopores.
