Indonesia: Semen Indonesia has decided to continue to develop its new factory in Rembang, Central Java following protests by some local residents. Semen Indonesia's CEO Suparni said that the construction is currently 60% complete, with production expected by October 2016.
Suparni admitted that the development of the factory has been opposed by some of the local residents. Residents of North Kendeng, experts and academics have criticized the development of the factory. Untung Sudadi, a geologist from the Bogor Institute of Agriculture said that the North Kendeng area, where part of the factory will be built, is a karst area, which collects water for local residents and can be susceptible to sinkhole formation and instability.
Similar to an underground basin, karst areas function as water catchment areas. "Karst is essential to maintain water supply," said Untung. He added that conducting mining activities in karst areas would cause environmental damage.
Suparni said that the Environmental Impact Assessment (EIA) for the cement factory has been completed. He also said that the presence of the factory would not disturb water supplies to the local society.
