JAKARTA - The Ministry of Public Works and Public Housing (PUPR) targets the construction of the Jlantah Dam, Karanganyar, Central Java, to be completed by the end of 2023.

"The target for completion (Jantah Dam) at the end of 2023 is hopefully to be achieved," said PUPR Minister Basuki Hadimuljono in a written statement received by VOI, Monday, June 26.

The Jlantah Dam, is one of 13 dams being built by the Ministry of PUPR throughout Indonesia this year.

A total of 12 other dams, namely Cipanas, Karian, Sepaku Semoi, Keureuto, Rukoh, Tiu Sunju, Lausimeme, Sidan, Leuwikeris, Temef, Pamukkulu, and Ameroro.

Basuki said that the Jlantah Dam has a capacity of 10.97 m3 sourced from the Jlantah River and Puru River.

Construction of the dam is designed with a height of 70 meters (from the bottom of the river), a peak length of 404 meters, a peak width of 12 meters, and an elevation of the dam peak of more than 690 meters.

Meanwhile, Director of Dams and Lakes of the Directorate General of Water Resources, Adenan Rasyid, said that this dam was built since July 2019 by PT Waskita Karya (Persero) and PT Adhi Karya KSO with a contract value of Rp965 billion.

"Currently, the progress is around 65 percent. Later, the Jelantah dam will irrigate 1,494 hectares of rice fields in the Jatipuro and Jumapolo areas, Karanganyar Regency," he said.

In addition to being an irrigation source, the Jlantah dam is also a raw water source with a capacity of 150 liters/second, and can reduce flooding by 51.26 percent or 70.33 cubic meters per second for Q50.

"The presence of this dam will also provide benefits for the potential for a Micro Hydro Power Plant (PLTMH) of 0.625 mega watts (MW), as well as for conservation and tourism in Karanganyar Regency," he said.

As a whole, in the 2015-2025 period, the Ministry of PUPR targets the completion of the construction of 61 dams which will increase the supply of premium irrigation water from 10.6 percent to 19.3 percent.
