The name of the new capital city of Indonesia has been announced, namely Nusantara. Located in Sepaku, East Kalimantan, Nusantara will replace Jakarta as the capital city.

There are a lot of Acacia industrial plantations owned by PT. Itci Hutani Manunggal. The government plans to rehabilitate the forest at the IKN location, Sepaku, into a tropical forest with endemic plants. More than just enriching the country with increased production, these forests have many benefits. Among them are helping forest conservation, improving land with productive forests, and helping local communities to improve their economy. The environmental impact of this forest is the increasing collection of biodiversity in Indonesia.

When industrial forest plantations are harvested, an excavator class model SH130LF-6 Macan Sumitomo is needed in the harvesting process (harvesting) at this location is a mineral / dryland area where the harvesting process is as follows:

1. Micro planning, initial felling plan that contains important information on the area to be harvested.

2. Pre Harvest (slashing), namely the activity of cleaning the area manually before logging activities, namely by slashing weeds.

3. Felling, namely logging activities based on a predetermined system and accompanied by the correct logging technique.

4. De limbing, namely the activity of cleaning wood from branches and twigs.

5. Cut to length, namely the activity of cutting or dividing the stem into pieces of a certain length (according to the standard mill).

6. Pre Bunching, namely the activity of stacking pieces of wood on a route that has been designed/determined and this activity can be done manually and mechanically (heavy equipment/excavator).

7. Stacking, namely the activity of stacking pieces of wood on a route that has been designed/defined and this activity can be done manually and mechanically (heavy equipment/excavator).

8. Extraction/Skidding, namely the activity of pulling wood from the pile of wood from the felled area to the tpn on a predetermined path.

9. Loading, namely the activity of loading wood with an excavator at the tpn to the logging truck/iron canoe

It is very suitable for work like this using the MACAN Sumitomo SH130LF-6 excavator which is not only very tough and fast to work for this job but is also fuel efficient, besides that it is also very reliable when carrying out the extraction because this MACAN uses a 20 ton class travel motor with a pulling force wood (drawbar pull) of about 171 kN, the largest in the 13 ton class, resulting in high productivity.

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.

These excavators are used for mining processes ranging from development, overburden, striping, coal getting and loading unloading. Sumitomo Excavator is strong in power, agile and fuel-efficient these are important points for the company in choosing Sumitomo Excavator as its main equipment in supporting coal mining production activities for the company.

Sumitomo also produces large class of 40-80 tons excavators such as the SH490LHD-6, SH510LHD-6 and SH800LHD models which is well accepted in the market place.
