Abstract

Kecamatan Balikpapan Selatan merupakan salah satu wilayah yang tergolong rentan terhadap bencana banjir, dengan luas wilayah mencapai 3.880,96 hektare. Topografi kawasan ini sebagian besar berupa dataran rendah, berada di sekitar aliran sungai, dan terletak di wilayah pesisir, sehingga menjadikannya sangat rawan terhadap banjir. Banjir di wilayah ini berkaitan erat dengan kondisi tata ruang dan lingkungan, seperti sistem drainase yang kurang optimal, terbatasnya infrastruktur mitigasi, minimnya kawasan resapan air, tingginya curah hujan, serta meluapnya sungai yang melintasi kecamatan tersebut. Penelitian ini bertujuan untuk menganalisis strategi mitigasi banjir berbasis pemanfaatan ruang yang disesuaikan dengan tingkat kerentanan wilayah. Dalam penelitian ini digunakan metode analisis overlay untuk menentukan tingkat kerentanan banjir, serta analisis deskriptif kualitatif dalam merumuskan rekomendasi mitigasi bencana. Hasil analisis menunjukkan bahwa wilayah dengan tingkat kerentanan tinggi meliputi Kelurahan Damai Bahagia, Damai Baru, Sepinggan, Gunung Bahagia, dan Sungai Nangka. Sementara itu, wilayah yang termasuk dalam kategori kerentanan sedang berada di Kelurahan Sepinggan Raya dan Sepinggan Baru. Mitigasi berbasis pemanfaatan ruang dapat dilakukan melalui pengendalian pemanfaatan lahan sesuai dengan rencana pola ruang, penerapan teknologi biopori atau sumur resapan pada kawasan terbangun, serta pengembangan wilayah dengan proporsi 70% area terbangun dan 30% ruang terbuka hijau.

Abstract

South Balikpapan District is prone to flooding due to its location near the Ampal River basin, high land use density, and intense rainfall. This study aims to develop guidelines for flood mitigation-based spatial utilization in residential areas of South Balikpapan. Overlay analysis was used to determine flood vulnerability levels, and triangulation analysis to formulate spatial utilization guidelines. The results show that residential areas in South Balikpapan have high and moderate flood vulnerability. About 55% of the area, including Damai Bahagia, Damai Baru, Sepinggan, Gunung Bahagia, and Sungai Nangka (332.16 ha), are highly vulnerable, while 45% in Sepinggan Raya and Sepinggan Baru (157.33 ha) are moderately vulnerable. The proposed spatial utilization focuses on mitigation: prevention through relocation and infrastructure strengthening, handling via improved drainage and evacuation systems, and recovery through adaptive spatial planning. Integrating spatial utilization and flood mitigation is crucial for creating safe and sustainable residential areas.
