Detiktoday.com – To meet national water and food security targets, specifically the supply of raw water of 54.81 m3 / sec in 2024, the Ministry of Public Works and Public Housing (PUPR) continues to build new dams in a number of provinces. These include the Tiu Suntuk Dam in West Nusa Tenggara, the Sepaku Semoi Dam in East Kalimantan, the Jragung Dam in Central Java, the Ameroro Dam in South Sulawesi and the Budong-budong Dam in West Sulawesi. Two of them have been contracted, namely Tiu Suntuk Dam and Sepaku Semoi Dam, the rest are in the auction process.
PUPR Minister Basuki Hadimuljono said the management of water and irrigation resources would continue in order to support sustainable agricultural production. Besides that the presence of the dam also has the potential of raw water, energy, flood control, and tourism that will grow the local economy. “The construction of dams is followed by the construction of the irrigation network. Thus the dam that is built at great expense can be beneficial because the water is certain to flow to the farmers’ rice fields, “said Minister Basuki some time ago.
Tiu Suntuk Dam is located in Mujahidin Village, Brang Ene District, West Sumbawa Regency, West Nusa Tenggara. This dam has a total storage capacity of 56 million m3 with a pool area of 337 ha.

Construction of the dam was carried out by the Nusa Tenggara River Region II (NTB) with the contractor PT Nindya Karya – PT Bahagia Bangun Nusa KSO for package I worth Rp 650 billion.
The Tiu Suntuk Dam can supply irrigated water covering an area of 1,743 ha and raw water in the Regency of West Sumbawa, 68 liters / second, supplying electrical energy potential of 0.81 MW, flood retention 425.68 m3 / second, and additional functions as conservation of water resources, tourism , and inland fisheries.
Furthermore, the contracted dam is the Sepaku Semoi Dam in Tengin Baru Village, Sepaku District, Penajam Paser Utara Regency, East Kalimantan. This dam has a storage capacity of 11 million m3 with a pool area of 232.51 ha.

The dam, which is targeted to be completed in 2023, is useful for 1,460 ha of irrigation water, flood reduction of 584 m3 / second, raw water of 511 liters / second and the provision of electrical energy potential of 1.3 MW. The estimated construction budget is IDR 1.62 trillion.
The Budong-budong dam, which will be built in Central Mamuju Regency, West Sulawesi, has a reservoir capacity of 65 million m3, targeted for completion in 2023 with the benefits of irrigation water supply covering 3,500 ha, flood reduction 106.76 m3 / second, raw water 410 liters / second and the supply of electrical energy potential of 0.6 MW. The cost of building this dam is Rp 1.34 trillion.
In addition to the construction of a new dam, in 2020 the Ministry of PUPR has completed construction and will soon be filling water in two dams namely the Tukul Dam in Pacitan and the Tapin Dam in South Kalimantan. The Tukul Dam has a capacity of 8.68 million m3 to supply 600 ha of irrigation and 300 liters / second of raw water. While Tapin Dam has a capacity of 56.77 million m3 for irrigation water supply covering an area of 5,472 ha.
