Abstract

Beberapa tempat di Kecamatan Ampenan pada saat musim hujan sering terjadi genangan. Luas total genangan mencapai 7,64 hektar dengan tinggi genangan 20–40 cm dan lama genangan 2–4 jam. Kondisi seperti ini terjadi 2–3 kali setahun. Melihat permasalahan tersebut, maka perlu dilakukan evaluasi terhadap sistem drainase yang ada untuk mengetahui strategi penanganan yang akan dilakukan dalam mengatasi permasalahan genangan.

Dalam mengevaluasi permasalahan genangan yang terjadi di wilayah Kecamatan Ampenan, akan dilakukan dengan pendekatan analisis terhadap aspek teknis (hidrologi dan hidrolika), aspek institusi/kelembagaan menggunakan metode analisis SWOT, dan aspek finansial (kebutuhan biaya pembangunan serta operasi dan pemeliharaan saluran drainase).

Hasil evaluasi menunjukkan bahwa genangan yang terjadi disebabkan karena kapasitas saluran tidak mampu menampung debit limpasan dan air buangan sehingga diperlukan peningkatan kapasitas saluran dengan rehabilitasi dan normalisasi. Dengan dilakukannya peningkatan kapasitas saluran, diharapkan terjadi pengurangan luas genangan sebesar 28,27% untuk tahap I (2008), 88,61% untuk tahap II (2009), dan tahap III (2010) diharapkan 100% genangan sudah dapat teratasi. Biaya yang dibutuhkan untuk rehabilitasi dan normalisasi saluran sebesar Rp588.725.000,00 dan dilakukan secara bertahap sesuai dengan prioritas penanganannya. Dalam upaya mengatasi masalah genangan, lembaga yang bertanggung jawab terhadap drainase di Kota Mataram (Dinas Pekerjaan Umum) perlu meningkatkan manajemen pengelolaan drainase, sumber daya manusia, serta koordinasi dan kerja sama antara pemerintah dan masyarakat.

In the rainy season, inundation frequently occurs in several areas of the District of Ampenan. The total inundated area is approximately 7.64 hectares, with a water depth of 20–40 cm and an inundation duration of approximately 2–4 hours. This condition occurs two or three times a year. Therefore, an evaluation of the drainage system in the District of Ampenan is necessary. The results of the evaluation will be used as input for developing a strategy to overcome the problems in the drainage system. Therefore, research needs to be conducted for this purpose.

This research will evaluate the inundation problems in the District of Ampenan. The analyses include technical, institutional, and financial aspects. Hydrological and hydraulic analyses are used to assess the technical aspect, SWOT analysis is utilized for the institutional aspect, and cost analysis for development is conducted to determine the financing strategy.

The results of the evaluation show that the runoff and wastewater discharge are greater than the capacity of the existing canals. Therefore, the canals need to be normalized and rehabilitated. It is expected that after the normalization and rehabilitation of the canals have been completed, the inundated areas will be reduced by (1) 28.27% in Stage I (2008), (2) 88.61% in Stage II (2009), and 100% in Stage III (2010). The cost of these efforts is approximately Rp588,725,000. The development process must be carried out in three stages (years) because the government’s allocated budget is limited. Moreover, the Dinas Pekerjaan Umum, the institution responsible for managing the drainage system, needs to improve its management system by implementing effective information and communication systems, improving the skills and knowledge of its human resources, and establishing good coordination and cooperation with communities and other institutions.
