Assessment of site suitability for water harvesting in Sentul City is an important, because the Sentul City area often problems with water supply and is expected to prediction a water deficit in 2050, other problems are floods often occur in the downstream during the rainy season. This study aims to analyze the suitability of the location for small dam and reservoirs determine the number of small dam and reservoirs that can be built in Sentul City based on location suitability maps. Identifying locations for the construction of small dam and reservoirs can use of Geographic Information System (GIS), the approach used multi criteria analysis and weighted overlay techniques with software ArcGIS. Six criteria were considered for this study, which include topographic factors (slope), land use, soil texture, rainfall, and distance to the river and distance to the road. The multi criteria analysis approach, each criterion was assigned a weight with slope being considered as the most important factor. Weighted overlay analysis was performed in ArcGIS and determination of suitable small dam and reservoir site was done from the summation of weight of each contributing factor. A final suitability map was generated which indicated that 34% of the total study area showed that the area was not suitable, 31% highly suitable, 27% was suitable, 6% was moderately suitable and 2% was low suitable for dam construction. Based on suitable map, 5 (five) samall dam and 9 (nine) reservoir can be used to water harvesting that can be used as raw water sources in Sentul City.

ABSTRAKPengelolaan DAS Aesesa Flores di Provinsi Nusa Tenggara Timur menjadi penting dan prioritas karena isu daerah kepulauan, kesulitan mendapatkan air bersih, ketersediaan pangan dan kemiskinan, serta keterbelakangan pembangunan. Keberhasilan pengelolaan DAS yang berkelanjutan sangat ditentukan oleh kinerja kelembagaannya. Penelitian yang dilaksanakan pada bulan April-Mei 2018 ini bertujuan untuk menganalisis peran kelembagaan ditinjau dari aspek kendala, kebutuhan program dan actor/lembaga yang berperan dalam pengelolaan DAS Aesesa Flores. Data yang digunakan adalah data primer dan sekunder, khusus data primer diperoleh dari 7 (tujuh) orang pakar melalui pengisian kuesioner. Metode analisis data menggunakan pendekatan ISM (Interpretative Strutural Modellling) untuk menentukan factor kunci yang paling berperan dalam pengelolaan region hulu, tengah, dan hilir DAS Aesesa Flores. Hasilnya bahwa pengelolaan DAS AF yang berkelanjutan masih menghadapi 9 kendala pokok, membutuhkan 11 program, terdapat 5 aktor utama yang berperan dalam pengelolaan DAS AF yakni BPDAS Benain Noelmina, Forum DAS NTT, BWS NTT2, Masyarakat dan LSM. Pengelolaan DAS AF masih bersifat eksploitasi, belum mengarah pada pembangunan berkelanjutan dan tidak didukung dengan kelembagaan yang mumpuni sehingga diperlukan segera upaya untuk mengatasi kendala, implementasi program pokok, dan peningkatan peran dan kordinasi actor/pelaku pengelolaan DAS AF yang berkelanjutan.ABSTRACTThe management on the Aesesa Flores (AF) watershed is important, particularly because of the imminent issues of clean water needs, food securities and a poverty rate of the local communities. The success of this management is influenced by the institution and governance in the AF watershed. This study was done from April to May 2018, and the main objective of the study is to determine the key factors that related to the AF watershed management. There were three main elements that were analyzed in this study, namely: (1) the key actors; (2) the key requirements; and (3) the key hindrances that influencing the AF watershed management. This study was using Interpretative Structural Modeling (ISM) to determine the key factors in each element. The data was collected primarily from an in-depth interview with 7 experts in the field of watershed management. The results from this study showed that there were 5 key actors that have the main influence in the AF watershed management, which are: (1) BPDAS (Governmental Watershed Institution); (2) Forum DAS (community forum of AF watershed); (3) BWS NTT2 (Regional River Management Institution); (4) Local communities; and (5) NGO (Non-Government Organization). The results from this study also suggested that the AF watershed management was explorative, thus may lead to unsustainable natural resources usage. Therefore, this study suggested that in order to achieve a sustainable watershed and natural resources usage, the relevant actors need to collaborate together to create a balance action plan that protects the environment, promoting economic growth and social affluence.Keywords: Aesesa Flores watershed, Interpetative Structural Modelling, watershed institution and governanceSitasi: Noywuli, N., Sapei, A., Pandjaitan, N.H dan Eriyatno (2018).
