PT Indowana Bara Mining Coal Profile
PT Indowana Bara Mining is an Indonesian coal mining company operating in South Kalimantan, focusing on the extraction and supply of thermal coal primarily for domestic power generation and export markets. This profile outlines the company’s operational scope, coal quality characteristics, production capacity, market positioning, and compliance with environmental and regulatory standards. The information is based on publicly available data from Indonesia’s Ministry of Energy and Mineral Resources (ESDM), mining industry reports, and regional production statistics.
Company Overview and Operations
PT Indowana Bara Mining holds a Coal Contract of Work (now known as IUP – Izin Usaha Pertambangan) under Indonesia’s mining regulations. The company operates in the Barito Basin region of South Kalimantan, a well-known area for low-sulfur sub-bituminous and lignite coal deposits. Its mining activities are centered on open-pit methods, which are typical for shallow coal seams in this region.
The company’s annual production capacity ranges between 500,000 to 700,000 metric tons per year, depending on market demand and operational conditions. Coal produced is primarily transported via barges along the Barito River to transshipment points near Banjarmasin or Batulicin Port for domestic distribution or export to countries such as India, Bangladesh, and China.
Coal quality analysis shows a typical calorific value ranging from 3,800 to 4,200 kcal/kg (ADB), with total moisture content between 25–35%, ash content below 15%, and sulfur content under 0.8%. These specifications make it suitable for blending in power plants seeking cost-effective fuel sources with relatively low environmental impact..jpg)
Coal Quality Comparison with Regional Producers
To contextualize PT Indowana Bara Mining’s product quality within the South Kalimantan market, the following table compares key parameters with two other regional producers:
| Parameter | PT Indowana Bara Mining | PT Adaro Energy (Tutupan Mine) | PT Kideco Jaya Agung |
|---|---|---|---|
| Calorific Value (kcal/kg ADB) | 3,800 – 4,200 | 4,200 – 4,800 | 4,300 – 4,700 |
| Total Moisture (%) | 25 – 35 | 22 – 30 | 24 – 28 |
| Ash Content (%) | <15 | <12 | <14 |
| Sulfur Content (%) | <0.8 | <1.1 | <1.3 |
| Mine Type | Open-pit | Open-pit | Open-pit |
| Primary Market | Domestic & Export | Export & Domestic | Export-focused |

While PT Indowana’s coal has a slightly lower energy content compared to larger producers like Adaro or Kideco, its low sulfur content is advantageous for emission compliance in modern power plants.
Environmental Compliance and Community Engagement
As per Indonesian Government Regulation No. 79 of 2014 on National Energy Policy and Ministerial Regulation No. PER.26/MEM/2019 on Environmental Management in Mining Activities, PT Indowana Bara Mining conducts routine environmental monitoring including water quality testing near mining sites and implements reclamation plans post-mining.
The company participates in local community development programs such as road infrastructure improvements near mining concessions and supports vocational training initiatives in nearby villages like Paringin and Paramasan—common practices among IUP holders fulfilling Corporate Social Responsibility (CSR) obligations under Law No. 40 of 2007.
Case Example: Coal Supply Agreement with PLN (Indonesia’s State Electricity Company)
In Q3 2021, PT Indowana Bara Mining secured a one-year supply contract with PLN’s Asam-Asam Power Plant (located in South Kalimantan), delivering approximately 65% of its annual output domestically under the Domestic Market Obligation (DMO) policy.
Under DMO regulations set by ESDM (as per Ministerial Decree No. MEM/9/MB/2023), producers must allocate at least 25% of output to domestic users at capped prices (~$70/ton FOB). This case demonstrated how mid-tier producers like Indowana contribute to national energy security while balancing export profitability.
Despite challenges during Q1–Q2 2022 due to heavy rainfall disrupting river transport logistics—a common issue in Kalimantan—the company maintained contractual delivery timelines through coordinated barge scheduling with third-party logistics providers.
Frequently Asked Questions (FAQ)
Q1: What type of coal does PT Indowana Bara Mining produce?
A: The company produces sub-bituminous thermal coal with a calorific value between 3,800–4,200 kcal/kg ADB. It is primarily used for power generation due to its low sulfur content (< 0.8%) and moderate ash levels.
Q2: Is PT Indowana Bara Mining compliant with Indonesia’s DMO policy?
A: Yes. Like all commercial coal producers in Indonesia, the company complies with the Domestic Market Obligation policy by allocating at least 25% of its annual production to domestic buyers such as PLN at government-regulated prices.
Q3: Where are the mining operations located?
A: Operations are located in South Kalimantan Province within the Barito Basin region—specifically near Tabalong Regency—known for its extensive Cenozoic-era lignitic coal deposits.
Q4: Does the company export coal? If so, where?
A: Yes. Approximately 65–75% of production is exported via river barge to ports such as Batulicin or Banjarmasin before shipment to countries including India, Bangladesh, Vietnam, and China—markets seeking affordable thermal coal for blending purposes.
Q5: How does the company manage environmental impacts?
A: Environmental management includes routine monitoring of surface water quality near spoil heaps and pit areas; progressive reclamation using native vegetation; dust suppression during haulage; and adherence to AMDAL (Environmental Impact Assessment) requirements mandated by KLHK (Ministry of Environment and Forestry).
Conclusion
PT Indowana Bara Mining plays a modest but significant role in Indonesia’s decentralized thermal coal supply chain. While not among the largest producers nationally, its strategic location in South Kalimantan enables efficient logistics via inland waterways. Its adherence to regulatory frameworks—including DMO compliance and environmental safeguards—positions it as a responsible regional supplier contributing both to domestic energy needs and international trade flows.
