Abstract

Dengan ditetapkannya Koto Tangah, yang merupakan salah satu kecamatan di Kota Padang, menjadi daerah pengembangan perumahan, secara tidak langsung menyebabkan Air Tawar-Ganting (suatu kawasan di Kecamatan Koto Tangah) menjadi daerah permukiman padat penduduk. Hal ini menyebabkan terjadinya perubahan fungsi lahan dari daerah resapan menjadi permukiman. Dampak yang terjadi saat curah hujan cukup tinggi (>223,03 mm/jam) adalah timbulnya banjir seluas 44,09 Ha dengan tinggi genangan hingga 60 cm selama lebih dari 6 jam. Melihat permasalahan tersebut, perlu dilakukan penelitian terhadap pengelolaan sistem drainase Air Tawar-Ganting yang diharapkan dapat memecahkan permasalahan di atas.

Kajian dilakukan dengan menggunakan metode deskriptif terhadap empat aspek, yaitu teknis, pembiayaan, kelembagaan, dan peran serta masyarakat. Hasil analisis menunjukkan bahwa banjir di daerah Air Tawar-Ganting disebabkan oleh kapasitas saluran yang tidak mampu menampung debit limpasan dan air buangan. Secara teknis, kebijakan yang dapat dilakukan adalah meningkatkan kapasitas saluran dengan biaya pembangunan sebesar Rp21,7 miliar. Akibat keterbatasan dana pemerintah kota, berdasarkan analisis kelayakan investasi dan analisis SWOT, kebijakan nonteknis yang dapat dilakukan adalah melakukan peminjaman dana kepada pemerintah pusat dengan bunga tidak melebihi nilai IRR, meningkatkan pengelolaan drainase pada kawasan wisata, mengusulkan pembentukan kerja sama dengan swasta dalam pemanfaatan drainase makro sebagai lokasi wisata air, serta melakukan pendekatan melalui lembaga adat untuk menyalurkan ide dari pemerintah dan masyarakat menyangkut pembangunan serta pemeliharaan prasarana.
==================================================================================================================================
Koto Tangah has been determined as one of the sub-districts in Padang. It has been developed into a settlement area. As a result, the Air Tawar-Ganting area (a sub-area of the Koto Tangah sub-district) has become densely populated, and the function of the land has changed from an open area to a settlement area. The effect of this change is that the area becomes easily inundated during high rainfall (>223 mm/hour). The inundated area is approximately 44.09 Ha, with a water depth of about 60 cm for more than 6 hours. Therefore, research on the drainage system management of Air Tawar-Ganting needs to be conducted. It is expected that the recommendations of the research can solve the problem.

This study was conducted using a descriptive method covering four aspects: technical, financial, institutional, and public participation. The results of the analysis show that inundation in the Air Tawar-Ganting area is caused by the fact that the dimensions of some channels are too small. To improve the capacity of the channels, a budget of approximately Rp21.7 billion is required. However, since the budget of the Padang City Government is limited, based on investment feasibility and SWOT analyses, the possible non-technical policies are (1) taking a loan from the Central Government with an interest rate lower than the IRR, (2) improving drainage system management in tourism areas to support the tourism industry in the City of Padang, (3) proposing a joint venture with private companies to utilize the existing macro-drainage system as a water tourism area, and (4) conducting socialization within communities through cultural community systems regarding the importance of public participation in the operation and maintenance of the drainage system.
