PLTU Trenggalek Drilling Blasting PT. Debonair Nusa Karya

The Dam located on the border area between Ponorogo and Trenggalek and the water source supplies by 2 main river nearby. Trenggalek City lay on the land cavity surrounded by the mountains, when rainy season occur this city always suffer from the flood, on the opposite, when the dry season comes Trenggalek suffers from dryness, because the land itself consist of the thick rock material, so it could not hold water underneath and the water just pass the city stright to the valley and finally end up in a sea.

Perhaps those two reasons urge the government to build a dam. The President Jokowi continues the project after a, mini bus booking, long dormant by previous president. The President demanding this project to be completed on 2017.

PT. Debonair Nusa Karya contribute the drilling and blasting service on the project, with a targeted volume of 1.500.000 BCM, it takes 6 months for DNK to completed PLTU Trenggalek Project.

“Six meters it’s a minimal width of the road, plus shoulder of the road 1 to 1.5 meter. If there are road less than that, for sure there are some our aspirations to increase the width. Anyway it would certainly be handled,” said Zamharir. However, he added, the project implementation, should be at higher priority. “As we saw earlier, along the mountainous village of Batu Itam to the village of Ujong Batu there a lot spot of potential landslides that if not treated immediately it would be dangerous for road users.

Sarulla geothermal project in North Sumatra (North Sumatra), which is projected to hit a national electricity crisis, will be fully operated at 2016.

President Director of PT. PLN Nur Pamudji, at Medan, said that Sarulla Geothermal Power Plant (PLTP) is has most capacity, among other project that involve in Second Stage of 10.000 MW Power Plant Accelerated Development Programs, where nearly 50 percent or 4952 MW comes from geothermal energy.

“Sarulla project completion process, does take longer time than predicted before, because at the beginning too many obstacles that obstruct the implementation of the project, but at the current state situation really conducive, certainly Sarulla will start produce electricity in 2016,” he said.

The PLTP Sarulla’s generated electricity by will be purchased by PLN with an average price of 6.79 cents per kWh.

Proyek berkapasitas 330 MW yang berlokasi di Wilayah Kerja Pertambangan (WKP) Panasbumi Sarulla milik PT Pertamina Geothermal Energy (PGE), di Kabupaten Tapanuli Utara (Taput) dan Kabupaten Tapanuli Selatan (Tapsel) Sumut, kontraktornya PT PGE yang merupakan konsorsium Medco-Ormat-Itochu-Kyushu (Konsorsium).
The project with a capacity of 330 MW was located in the Mining Working Area (WKP) Sarulla Geothermal belongin to PT Pertamina Geothermal Energy (PGE), in North Tapanuli (Taput) and South Tapanuli (Tapsel) of North Sumatra, PT PGE (the contractor) is a consortium of Medco-Ormat- Itochu-Kyushu (Consortium).

Nur Pamudji asserted, Geothermal has become a national priority sectors of energy, which is have the enormous potential, estimated to reach 29,000 MW.

Currently Indonesia with installed capacity of about 1,341 MW is the third largest producer of geothermal electricity in the world, after the United States and the Philippines.

Dia menjelaskan, pembangunan PLTP Sarulla akan dibagi dalam tiga tahap dan akan selesai pada tahun 2018 atau merupakan tahap ketiga.
He explained, Sarulla geothermal power plant construction will be divided into three stages and the final stage will be completed in 2018.

“PLN hoped that the project runs smoothly because it can help reduce the energy crisis,” he said.

Furthermore, the Sarulla’s electricity supply will be projected for an exports to Malaysia.

He said the state reserves for North Sumatra that was mediocre due to the rapid growth of industrial and other commercial activities that have not been fully met PLN supply, actually in 2004, PLN had asked the governor to build hydropower Asahan 2, but it was given to another company that in fact do not have the funds so that the project did not running until today. However, for the construction of Asahan 3, PLN had issued a permit on January 4, 2012 because it has given by North Sumatra Governor Gatot Pujo Nugroho, who was still acting as Governor of North Sumatra.
