Stone Quarry Supports Infrastructure Development in Indonesia

Infrastructure development in Indonesia is being accelerated to be completed soon therefore there should be supported from various parties to be involved in supporting the development from upstream to downstream from the provision of construction raw materials and also need to be supported with appropriate construction equipment technology.

Regarding the support of raw materials for such construction such as the provision of stone for road construction and building, the raw material of the stone is taken from many stone quarry companies that produce excellent quality of stone to construct a strong and durable construction. For example in the area Rumpin, Bogor is a stone producer whose quality is very good. Many of the stone quarry companies in the area supply stone raw materials to government development projects in support of the government in accelerating development in Indonesia such as road construction, concrete for bridges and concrete structures which are currently widely required in the construction of railway lines LRT. 

One of the big stone quarry companies in Rumpin, Bogor, namely PT. Gunung Mas Jaya Indah (PT GMJI) with excellent quality is participating in supplying about 70% of its production to government projects through several Indonesian state-owned companies. This company has been established since 1984 and continues to grow and began to join venture with foreign companies around the year 2010. This company certainly can not be separated supported also by technology of construction tools that are reliable and very helpful in the production process such as drill machines, loaders, dozers and excavators in order to compete in the market in a lot of stone supply and quality.

Support from the construction equipment technology owned by the stone quarry company has an important role, just take the Excavator example. This excavator serves to dig and take the stone where before it is done first blasting on the rock cliffs at the mine site. PT. GMJI entrusts its Excavator in the 20 ton class by using the Sumitomo SH210-6 brand that is the latest technology generation from Sumitomo brand excavator manufacturer where strong, tough, powerful and fuel efficient also comfortable to operate.

Sumitomo Excavator for Coal Mining Work

Wednesday April 4, 2018

Coal is the dominant force in electricity generation and its extraction process is relatively easy and inexpensive, and infrastructure requirements are cheaper than other energy resources.

The world is already aware of reducing dependence on coal (fossil fuels), but current renewable energy sources still do not indicate that the world’s dependence on coal will decline significantly in the near future, so that coal continues to be a promising energy source.

However, clean coal technology in coal mining will be very much needed in the future (partly due to commercial factors) and Indonesia is expected to be actively involved in the process as one of the main actors in the coal mining sector. The clean coal technology is focused on reducing emissions produced by coal-fired power plants but this technology has not developed well enough.

There are many small coal reserves in Sumatra, Java, Kalimantan, Sulawesi and Papua, but three of the largest coal reserves in Indonesia are South Sumatra, South Kalimantan and East Kalimantan. Indonesia has the main destination countries for coal exports, namely China, India, Japan and South Korea.

Therefore many mining companies in Indonesia are continuing to get this energy source and they need excavators in their mining activities as their main equipment. In this case, several mining companies entrust their excavators to Sumitomo Excavators like one of them at a coal mine in the Banjarmasin area. This company operates Sumitomo excavators models of SH210-6 20 tons class and SH350LC-6 30 tons class.

The company utilizes some heavy equipment such as excavators, trucks, and dozers of various brands, mostly of Japanese brands. One piece of equipment they operate is the Japanese-brand excavator “SUMITOMO” made in Karawang, West Java, Indonesia. All are of Japanese quality.

Mr. Djoko has recently purchased ten units of the new SUMITOMO excavator 20 ton SH210-5. This is a repeat order from his first trial of 10 units several months ago, bringing his current fleet of excavators to 20 SUMITOMOs.

Mr. Djoko also has just signed a PO for another batch of 10 units of SH210-5 for short-term deliveries.
