Abstract

The availability of sufficient and good quality water is essential for the survival of both humans and the environment. However, in several regions, water resources have been declining due to various factors such as land use changes and excessive exploitation. Ketapang Regency, located in West Kalimantan Province, is one of the areas facing challenges related to water carrying capacity. This study was conducted to spatially analyze the water carrying capacity in Ketapang Regency. The method used is descriptive with a spatial approach. The data used in this study are secondary data, and the analysis techniques include the water vulnerability index and descriptive analysis. The results indicate that most areas in Ketapang Regency exhibit a high level of water vulnerability. This finding highlights the urgent need for better water resource management to minimize the risk of water shortages and negative impacts on both the environment and society. This research is expected to serve as a reference for decision-making in water resource management policies in Ketapang Regency.

Abstract

Kecamatan Babelan merupakan salah satu wilayah di Kabupaten Bekasi yang sedang berkembang dalam sektor industri dan properti. Namun, terdapat berbagai macam permasalahan yang salah satunya adalah banjir yang diakibatkan oleh meluapnya Kali Bekasi. Tinggi banjir yang terjadi berkisar antara 20-100 cm. Banjir tersebut sering kali menghambat aktivitas masyarakat setempat dan dapat menyebabkan kerugian fisik dan material. Oleh karena itu, diperlukan solusi yang dapat mereduksi banjir yang terjadi karena luapan Kali Bekasi. Pemodelan banjir dan analisis hidraulika dalam tugas akhir ini dilakukan dengan dan bantuan perangkat lunak HEC-RAS 6.5 dan menggunakan debit rencana periode ulang 20 tahunan sebesar 559.79 m3/s. Terdapat tiga skenario alternatif solusi yang dimodelkan yaitu normalisasi, tanggul, dan normalisasi + tanggul. Dengan mempertimbangkan efektivitasnya, dipilih alternatif solusi berupa normalisasi + tanggul. Normalisasi yang dilakukan adalah dengan melebarkan alur Kali Bekasi selebar 40 meter dan tanggul yang digunakan adalah jenis sheet pile. Kombinasi dari normalisasi dan pembangunan tanggul diharapkan dapat menjadi solusi dari permasalahan banjir di Kabupaten Babelan akibat luapan Kali Bekasi.

Abstract

Pekalongan City, located on the northern coast of Central Java, is vulnerable to flooding due to high rainfall, low land elevation, land subsidence, sea level rise, and uncontrolled human activities. The Banger River, originally constructed as an artificial river to reduce flooding from the Loji River, has now become a source of flooding. This study aims to identify technical flood control solutions for the Banger River using spatial, hydrological, tidal, and hydraulic analyses supported by hydraulic flow modeling software. Twenty years of rainfall data, spatial data, river geometry, and tidal information were used to simulate existing and projected long-term conditions. The design flood discharge with a 20-year return period was calculated at 281,9 cubic meters per second, resulting in an average inundation of 0,27 meters, which may rise to 0,85 meters within the next ten years due to land and sea level changes. Three alternatives were evaluated: normalization with earth embankment, a combination of normalization and parapet, and parapet-only implementation. Results indicate that using parapets, or combining them with river normalization and embankments, offers the most technically effective flood control solution in both short and long terms. Overall, the study emphasizes the need for adaptive flood management strategies in coastal urban areas. It is recommended that local governments integrate structural measures with nonstructural policies, such as land use regulation and public awareness, to ensure sustainable flood risk reduction.
