The island of Kalimantan, with an area of over 743,330 square kilometers, has long been a region teeming with economic potential but hampered by connectivity challenges. Rugged terrain, large rivers, and dense tropical forests make it difficult to optimally develop conventional land transportation.
Amid the pressing need for an efficient logistics system, the Trans Borneo Railways initiative emerged as a strategic breakthrough. This trans-Kalimantan railway project is not only designed to lower logistics costs that have burdened businesses, but also to connect strategic areas, including direct access to the Indonesian Capital City (IKN) in East Kalimantan.
Currently, the distribution of goods in Kalimantan relies heavily on river and land transportation, which are in relatively limited condition. Large rivers like the Kapuas, Barito, and Mahakam serve as the backbone of logistics, but still face limitations during the dry season when water levels decrease.
Meanwhile, land roads are often damaged, riddled with potholes, and poorly connected between provinces.
Therefore, as a result, inter-regional logistics costs on the island of Kalimantan are quite high. For example, shipping costs from Balikpapan to Pontianak via land and river routes can be two to three times higher than the same distance on Java.
In fact, in inland areas like Kapuas Hulu or Mahakam Ulu, logistics costs can soar up to fivefold. This situation ultimately makes the prices of basic necessities in the interior of Kalimantan very high, while also stifling the competitiveness of Kalimantan's leading products, such as coal, palm oil, rubber, and forest products.
Trans Borneo Railways' Grand Vision
The Trans Borneo Railways is designed as a railway network stretching from the western tip of Kalimantan in Pontianak to the eastern tip in Samarinda and Balikpapan, with branches to the Indonesian capital.
Gradually, this network is expected to reach the northern region as far as Tarakan and the southern region as far as Banjarmasin and Palangkaraya. The total planned track length is over 2,000 kilometers, making it one of the largest inter-island railway projects in Indonesia.
The proposed system involves the procurement of heavy rail trains with dual standards for both freight and passenger transport. The primary priority in the initial phase of land transportation development is providing freight transport, given the pressing need in several regions of Kalimantan to reduce the high logistics costs of premium commodities.
Reducing Logistics Costs: Mechanisms and Impact
The reduction in logistics costs through the Trans Borneo Railway occurs through several mechanisms. First, efficiency of scale. A single train set can carry the equivalent of 40 to 50 trailer trucks simultaneously.
With this large capacity, costs per ton per kilometer can be reduced by 60-70 percent compared to trucks, and 40-50 percent compared to river transportation.
Second, speed and reliability of travel times. Trains with dedicated tracks avoid congestion, are not affected by seasonal changes, and have a fixed schedule.
A trip from Pontianak to Balikpapan, which currently takes 5-7 days via land and river routes, can be shortened to just 18-20 hours by train. This certainty of arrival time is invaluable for industries that require timely supply chains.
Third, reduction in damage to goods. Slow and wet river transportation, along with bumpy land roads, often cause damage to goods, especially commodities like rice, fertilizer, or other agricultural products. Railways offer greater stability and protection.
The impact of these reduced logistics costs will ultimately be felt widely and felt by the people. Palm oil producers in West Kalimantan will easily be able to ship crude palm oil to refineries in Balikpapan at a much lower cost.
Coal from the Kutai Kartanegara region can be transported to export ports with high efficiency. Consumer goods from ports in Kalimantan's main cities to the interior will become more affordable, ultimately contributing to lower regional inflation.
Connecting Strategic Areas Between Major Cities
One of the main advantages of the Trans Borneo Railway is its ability to connect strategic economic areas that have previously operated independently.
Mining and Energy Areas. The railway will pass through the coal belt in Samarinda, Tenggarong, and Muara Wahau.
Direct access from the mines to coal ports in Balikpapan or Bontang will reduce dependence on slow river barges. In addition to coal, this line can also support the distribution of oil and gas from refineries in Balikpapan.
Plantation and Agribusiness Areas. West and Central Kalimantan are the granaries of palm oil and rubber. Through the use of railways, plantation products can be transported to processing plants or ports without the long chain of trucks and rivers. Palm oil derivative products, such as oleochemicals, will be more competitive in the export market.
Export Product Processing Industrial Areas. Integrated industrial areas in Balikpapan, Samarinda, and Bontang will be directly connected to raw material sources from the hinterland.
Conversely, industrial products such as fertilizer, cement, and building materials could in the future be distributed throughout Kalimantan at a low cost.
Developing Tourism Areas. Although not currently a top priority, the availability of a railway network will eventually open access to tourist destinations such as Kayan Mentarang National Park, Lake Sentarum, or the Dayak cultural area. This will undoubtedly stimulate the growth of the creative economy and local community-based tourism.
Strategic Route to the Indonesian New Capital
The most crucial aspect of the Trans Borneo Railways project is a direct connection to the Indonesian National Capital (IKN). The hope is that, as the new capital city under construction, Nusantara will become a center of government, a hub of innovation, and a sustainable smart city. Efficient logistics governance is an absolute prerequisite for the IKN's success.
A branch line to the IKN is planned to connect from the main hub in Balikpapan or Samarinda. Using the railway, materials needed for the IKN's construction, such as cement, steel, and prefabricated building components, can be shipped from Balikpapan's port at low cost and in large volumes.
Once the IKN is operational, the railway will become the backbone of the distribution of daily necessities for residents and workers, from food to fuel.
Equally important, the railway will reduce congestion and the burden on land roads to the IKN. Without this mode, the flow of logistics trucks would be extremely congested and quickly damage the newly constructed road infrastructure.
The railway is a sustainable solution that aligns with the IKN's vision of a green, low-carbon city.
The railway line to the new capital will attract investment along the corridor. Buffer zones such as Penajam Paser Utara and Kutai Kartanegara will develop into logistics and light industry centers directly connected to the capital.
Challenges and Solutions
A project as large as the Trans Borneo Railway certainly faces significant challenges. First, it requires a massive investment, estimated at hundreds of trillions of rupiah. The solution is a blended financing scheme, utilizing the state budget for the core line connecting the capital city, and a government-private partnership scheme for commercial routes such as coal and palm oil transportation.
Second, Kalimantan's terrain is peaty and hilly. Construction technologies such as trenching for soft soil and tunneling for hilly areas must be implemented to the highest standards. The experience of building railway lines in Sumatra's peatlands provides valuable lessons.
Third, environmental impact. Railway construction must undergo a thorough environmental impact analysis, avoid conservation areas, and establish wildlife corridors. A commitment to sustainability is absolutely essential.
Fourth, coordination across provincial governments and sectors. A special body at the authority level is required, which will be given full mandate and responsibility for planning, construction, cross-border operational management, and monitoring and evaluation.
The Trans Borneo Railways is clearly more than just a transportation infrastructure project. It is a new foundation for Kalimantan's economic ecosystem, which has been hampered by high logistics costs and weak connectivity.
By reducing transportation costs by tens of percent, this project is believed to unlock the economic value of leading commodities, attract investment to inland areas, and provide more equitable access to basic services.
Directly connecting the Indonesian capital city, this project is the lifeblood of the successful relocation of the capital city to Jakarta. The railway line will transport building materials, daily supplies, and economic energy to the new center of government, while keeping the capital city green and free from congestion.
Significant challenges await, from allocating state budget funding to a shared commitment to environmental sustainability. However, global experience shows that no country has successfully emerged from economic backwardness without a serious commitment to building efficient mass connectivity.
The Trans Borneo Railways is the answer to the call of the times, by lowering logistics costs, connecting civilizations across regions, and enabling the island of Kalimantan and the Indonesian capital to leap into a more prosperous and equitable future.
Now is the time for execution, as every year of delay in infrastructure development means trillions of rupiah in losses due to high logistics costs that continue to erode the competitiveness of Kalimantan and Indonesia as a whole in entering the international market.
