JAKARTA - PT Semen Indonesia (Persero) Tbk (SIG) has contributed to the construction of the Sidan Dam in Bali which will maintain the safety of clean water supply for millions of Denpasar people and its surroundings. Until February 2025, GIS has supplied 76,000 tons of cement building materials for the construction of the National Strategic Project (PSN).

SIG's Corporate Secretary, Vita Mahreyni said, Sidan Dam is an important infrastructure that provides many benefits in people's social lives, as well as supports economic growth and environmental conservation actions.

"SIG is proud to be able to continue to contribute to national development such as the Sidan Dam which has a strategic role to support the realization of water and energy self-sufficiency which is part of Asta Cita Presiden Prabowo Subianto. This is also in line with the direction of the Minister of SOEs, Erick Thohir, so that SOEs contribute to infrastructure development that has a positive impact on economic growth and community welfare improvement," said Vita Mahreyni, in a written statement, Friday, March 14.

The Sidan Dam, located in Badung, Gianyar and Bangli Regencies, is a zonal-type dam with an asphalty core that is 197 meters long and 68 meters high with water sources coming from the Ayung River. The dam with a capacity of 3.82 million m3 will provide raw water as much as 1,750 liters per second for four areas in Bali, including Denpasar, Badung, Gianyar, to Tabanan, with an estimated total beneficiary of 1.3 million people.

In addition to providing raw water, the Sidan Dam will also function as a Micro Hydro Power Plant (PLTMh) with a capacity of 0.65 MW, and has the potential for floating PLTS to float 20 percent of the inundation area with a capacity of up to 8 MW. The Sidan Dam is also equipped with an evader tunnel that functions as flood control.

Vita Mahreyni emphasized that cement products from GIS have proven advantages in a number of national strategic projects. These advantages include being easily applied and having high strength, thus facilitating the construction process with strong concrete final results. Semen SIG is also categorized as green cement with an emission rate of up to 38 percent lower than conventional cement, as well as a high level of domestic components (TKDN) reaching 96.95 percent.

As the provider of the leading building material solution in Indonesia, GIS has a variety of innovative building materials with a complete specification range and support for a wide operational infrastructure network. With all the advantages it has, SIG is ready to make sustainable development successful throughout Indonesia," said Vita Mahreyni.
