Indonesia now publishes a price per hectare for reclamation, and asks miners to value the ecosystem before reopening land

Indonesia has quietly acquired something that many resource economies still lack: a published, official price for putting mined land back into productive condition. Keputusan Menteri ESDM No. 344.K/MB.01/MEM.B/2025, effective 23 October 2025, sets a standard reclamation cost per hectare for every province, year by year, for the period 2025 to 2030. The figure is not a guideline. It is the basis on which reclamation guarantees are calculated and placed.

That change matters well beyond compliance paperwork. Once the state publishes what a hectare of recovery costs, land condition becomes a line item with a number attached, and the whole conversation about mining and the environment shifts from adjective to arithmetic.

A national cost standard replaces company estimates

Kepmen 344 replaces the technical guidance issued in 2018 as Kepmen ESDM No. 1827 K/30/MEM/2018 and sets out four technical guidelines covering the full cycle from planning through to the evaluation of reclamation success. The cost annex is where the practical weight sits. In Nusa Tenggara Barat the standard for 2026 is Rp196.6 million per hectare. In East Kalimantan the standard reaches Rp205.4 million per hectare by 2030. Bauxite operations place a guarantee equal to 50 percent of the standard cost per hectare.

The standard covers direct costs such as land preparation, revegetation and acid mine drainage prevention, alongside indirect costs including mobilisation, planning, administration, supervision and third party margin. Companies calculate the guarantee at the future value of the final year of the planned reclamation period, referenced to prevailing bond interest rates, so that the money set aside today still buys the work required years from now.

The form of the guarantee has narrowed as well. Bank guarantees, joint accounts and accounting reserves are no longer accepted. The instrument is a fixed term deposit at an Indonesian government bank, held in the name of the permit holder or the governor, denominated in rupiah or US dollars. Horas Pasaribu, Coordinator of Environmental Protection for Minerals and Coal at the Ministry of Energy and Mineral Resources, has explained the design plainly: the guarantee is deliberately set above the cost of the reclamation work itself, so that finishing the job and recovering the deposit is the cheaper path for any operator.

A guarantee priced above the cost of the work turns land recovery from a discretionary expense into the cheapest available option. That is regulatory design doing quiet, useful work.

The timetable is equally specific. Reclamation plans are submitted within 45 working days of obtaining an IUP or IUPK at each stage, with a 45 working day approval window and a 20 working day correction period. Post mining plans carry a 75 working day approval window. Plan changes that affect success criteria are due by 31 July each year. Guarantees for the operations stage are placed within 20 working days of approval, and post mining guarantees must reach 100 percent of the required value two years before the permit concludes. Post mining work must be completed within five years of permit expiry, with one three year extension available. Guarantee funds are released once reclamation reaches at least 60 percent of its success criteria.

Ecosystem valuation moves from the courtroom to the permit desk

The most significant provision for anyone working on environmental economics is the treatment of PKAR, the reopening of an area that has already been reclaimed. An operator seeking to reopen reclaimed land must first show that cumulative reclamation has reached at least 50 percent of total land opened, must commit to accelerated reclamation covering at least three times the area to be reopened, and must submit two analytical documents: an environmental economic valuation and a cost benefit analysis.

The valuation is not a formality. It requires the applicant to put a monetary figure on standing timber and on environmental services, specifically erosion and landslide prevention, oxygen production and carbon absorption. The cost benefit analysis must then demonstrate that the economic benefit of reopening exceeds the environmental damage cost that reopening creates. Where safety or pollution risk makes reopening urgent, the economic viability test may be waived, with quarterly reporting required throughout implementation.

This is a meaningful institutional step. Ecosystem services valuation in Indonesia has largely lived in litigation, applied after damage occurred under Permen LH No. 7 Tahun 2014 to calculate environmental economic loss and recovery cost. Kepmen 344 moves the same discipline forward in time, to the moment a decision is being made rather than the moment it is being judged. The methodology is broadly the same. The purpose is entirely different.

Verification has been restructured to match. The decision separates two third party roles: implementers, appointed through a tender mechanism to carry out reclamation using the guarantee funds where an operator does not meet its obligations, and assessors, independent service providers who evaluate reclamation success in the field. The decision also extends a full reclamation framework to marine areas for the first time, covering artificial reefs, coral transplantation, mangrove planting, abrasion barriers, fish shelters and biota restocking, with success weighted across location determination at 20 percent, programme type at 20 percent and activity scale at 60 percent.

Sequencing the instruments for community mining

The framework drew fresh attention on 1 August 2026, when R. Haidar Alwi, founder of the Haidar Alwi Institute and vice chair of the ITB alumni board, set out how three instruments currently touch the same reclamation obligation for community mining. Kepmen ESDM No. 174.K/MB.01/MEM.B/2024 folds physical reclamation work into the environmental component of Iuran Pertambangan Rakyat, with 75 percent of that obligation due within 30 calendar days of permit issuance. Kepmen ESDM No. 344.K/MB.01/MEM.B/2025 sets the cost standard on which the guarantee value rests. Permen ESDM No. 18 Tahun 2025, signed on 14 November 2025, requires holders of an Izin Pertambangan Rakyat to deposit 10 percent of every mineral sale into an account held jointly in the names of the governor and the permit holder.

Each instrument is coherent on its own terms. Read together, they use different calculation bases, payment timings, custody arrangements and withdrawal mechanisms for a single restoration duty. For a cooperative holding an IPR of up to 10 hectares, or an individual holding up to 5 hectares within a WPR block capped at 100 hectares, the difference between those instruments operating in sequence and operating in parallel is material. A guarantee of Rp196.6 million per hectare implies roughly Rp1.966 billion for ten hectares opened across five years, a figure that a cooperative can plan for if it is the ceiling, and cannot easily plan for if it is one of several parallel demands.

The proposal put forward is straightforward and constructive. Treat the published cost standard as the binding ceiling on the total guarantee. Use the 10 percent sales deduction purely as the collection mechanism that fills that ceiling, and stop deducting once it is reached. Then set out clearly how funds are disbursed, how interest is treated, and how any surplus is returned. As Alwi framed it, the government is obliged to provide legal certainty, and one restoration duty should not become several overlapping payment duties.

Sirkularium's view

For government and public institutions, the substance of Kepmen 344 is a genuine advance. Indonesia now has a transparent, province specific price for land recovery, a guarantee instrument that is difficult to leave unfunded, an independent assessment function, and a formal requirement to value ecosystem services before land is reopened. That combination is more complete than what most peer jurisdictions in the region have in place, and it gives regulators a defensible number to work from rather than a negotiation.

The remaining work is sequencing rather than substance, and it is concentrated where administrative capacity is thinnest. Cooperatives and individual permit holders entering the formal system this year need the three instruments presented as one pathway with one ceiling, one custody arrangement and one clear release mechanism. Provincial governments carrying the WPR designation workload need the same clarity to advise applicants. Publishing a consolidated calculation example, showing how the IPERA environmental component, the cost standard and the 10 percent deduction resolve into a single guarantee balance, would likely settle most of the question at low cost.

For operators, the practical implication of the PKAR provisions is that environmental economic valuation is now a planning input rather than a defensive exercise. A valuation assembled under pressure, after a dispute has started, is expensive and rarely persuasive. A valuation built as ongoing practice, combining GIS and remote sensing evidence of land cover change with ground measurement of soil, water, biodiversity and carbon condition, and applying the methodology the state already recognises, produces something quite different: a defensible record of environmental position over time. That record supports a PKAR application, informs AMDAL commitments, substantiates a guarantee release claim at the 60 percent threshold, and stands up if a valuation is ever contested.

What to watch next is whether the Directorate General of Minerals and Coal issues consolidated guidance for community mining ahead of the 31 July plan change deadline in 2027, and whether the first PKAR approvals under the new valuation requirement establish a consistent methodology for pricing standing timber and environmental services. Those first decisions will set the practical standard for everyone that follows.
