“…Another study evaluating the effectiveness of technologies for artificial recharge and rainwater harvesting in Iran suggested that an artificial groundwater recharge system could inject new groundwater in volumes up to hundreds of thousands of m 3 during the dry season and 4.5 x 106 m 3 during the rainy season [8]. Similar studies have been carried out in Timor, Indonesia suggesting the effectiveness of water harvesting method, also known as embung, for many years [10,[14][15][16].…”

People have used rainwater harvesting (RWH) technology for generations to a considerable extent in semi-arid and arid regions. In addition to meeting domestic needs, this technology can be utilized for agricultural purposes as well as soil and water conservation measures. Modeling the identification of the appropriate pond’s location therefore becomes crucial. This study employs a Geo Information System (GIS) based multi-criteria analysis (MCA) approach and satellite rainfall data, Global Satellite Mapping of Precipitation (GSMaP) to determine the suitable locations for the ponds in a semi-arid area of Indonesia, Liliba watershed, Timor. The criteria for determining the location of the reservoir refer to the FAO and Indonesia’s small ponds guideline. The watershed’s biophysical characteristics and the socioeconomic situation were taken into consideration when selecting the site. According our statistical analysis, the correlation coefficient results of satellite daily precipitation were weak and moderate, but the results were strong and extremely strong for longer time scales (monthly). Our analysis shows that about 13% of the entire stream system is not suitable for ponds, whereas areas that are both good suitability and excellent suitability for ponds make up 24% and 3% of the total stream system. 61% of the locations are partially suited. The results are then verified against simple field observations. Our analysis suggests that there are 13 locations suitable for pond construction. The combination of geospatial data, GIS, a multi-criteria analysis, and a field survey proved effective for the RWH site selection in a semi-arid region with limited data, especially on the first and second order streams.

“…Tingkat kebutuhan air irigasi pada muasim tanam I menggunakan metode KP-01 yaitu sebesar 2,169 l/dt/ha dan pada musim tanam II kebutuhan air irigasi sebesar 4,894 l/dt/ha (Wardani & Kurniati, 2022). Neraca air untuk pola tanam padi-padipalawija aternatif 1-alternatif 4 mengalami surplus air dengan surplus air paling tinggi sebesar 2,40 m3 /detik pada perhitungan secara manual dan 4,55 m3 /detik dengan menggunakan Program Cropwat 8.0 (Bunganaen et al, 2022).…”

Wilayah semi arid merupakan daerah yang memiliki curah hujan yang rendah dan iklim yang kering, sehingga pertanian di wilayah tersebut seringkali menghadapi tantangan dalam hal ketersediaan air Kebutuhan air tanaman kangkung dipengaruhi kondis iklim dan koefisien tanaman yang berubah setiap fasenya. Dalam penelitian ini, digunakan metode Cropwat 8.0 untuk mengestimasi kebutuhan air tanaman kangkung. Cropwat 8.0 adalah sebuah model yang dikembangkan oleh FAO yang digunakan untuk menghitung kebutuhan air tanaman berdasarkan faktor-faktor seperti jenis tanaman, iklim, dan kondisi lingkungan. Evaotranspirasi tanaman (ETc) dengan menggunakan software CropWat 8.0 selama masa pertumbuhan adalah 294.8. Perlakuan pemberian air berpengaruh terhadap pertumbuhan dan produksi tanaman kangkung. Hasil penelitian menunjukan bahwa pengurangan pemberian air dari estimasi Cropwat memberikan pengaruh terbaik untuk tanaman kangkung di wilayah semi arid. Berdasarkan hasil penelitian untuk usaha tanaman kangkung di wilayah semi arid terberat terjadi pada P2 dan P3 yaitu masing – masing perlakuan adalah 16 gram . Hasil ini cukup sesuai dengan kondisi di lapangan untuk merencanakan awal musim tanam. Namun demikian, pengoperasian irigasi harian perlu tetap dilakukan berdasarkan pengamatan kondisi aktual di lapangan untuk mempertahankan kadar air tanah berada pada rentang yang sesuai untuk pertumbuhan tanaman.

Jatiluwih Village is located in Penebel District, Tabanan Regency, Bali. Jatiluwih Village is a highland village located at the foot of Mount Batukaru. This village is located at an altitude of 500-1500 meters above sea level and has an average rainfall of 2500 mm/year. Most of the population in the Jatiluwih area still relies on the economy of planting rice, with a good irrigation system. Rice fields in the Jatiluwih irrigation area need protection and preservation so that their area does not decrease. This priority is necessary because the meaning of land, including paddy fields is very important for humans, not only to own, but also to live their lives. Irrigation is an effort made to obtain water by using intake buildings and carrier channels. The Jatiluwih Irrigation Area has water sources from several springs that flow in the Jatiluwih Area. Jatiluwih weir with water sources from Tukad Baat has an irrigation area of 390 ha. The subaks that are irrigated by the Jatiluwih Dam are Jatiluwih Subak, Subak Gunungsari, Subak Kedamaian and Subak Wangaya Betan. The development and management of irrigation networks will greatly assist water-using farmers in an effort to increase the production of agricultural products, especially rice.
