Before the first pile is driven, every new factory in Indonesia must hold a valid environmental approval. This is not a paperwork formality — without it, the business's Nomor Induk Berusaha (NIB) in the OSS system can be frozen, halting construction mid-project. For investors building a plant or warehouse inside an industrial estate, understanding the AMDAL, UKL-UPL, and SPPL tracks early saves time, money, and the risk of disputes later.
This guide covers the current legal basis, the OSS-RBA and Amdalnet filing flow, cost estimates, penalties for non-compliance, and how construction material choices influence a factory's environmental impact assessment.
Why a Factory Needs Environmental Approval Before Construction
The environmental permit — now called Persetujuan Lingkungan under the Job Creation Law — is a hard prerequisite before the Building Approval (PBG) and other operating permits can be issued. The process evaluates a business's potential impact on air, water, soil, and surrounding communities before construction starts, not after.
Without this document, a factory risks a forced work stoppage from the local Environment Agency (DLH) the moment a field inspection occurs. In many cases, retrofitting an already-built structure to meet requirements costs far more than securing the permit upfront.
Three Instruments: AMDAL, UKL-UPL, and SPPL
Under Government Regulation (PP) 22/2021 on Environmental Protection and Management, the required document is now determined by the business's risk level rather than capital size alone.
- AMDAL — mandatory for businesses with significant environmental impact, such as large-scale factories, new industrial estates, or operations generating large volumes of hazardous waste. It involves in-depth studies, public consultation, and review by the AMDAL Assessment Commission.
- UKL-UPL — for medium-impact businesses that already follow standard technical management practices, such as mid-size factories with limited hazardous or non-hazardous waste. If the site sits inside an industrial estate that already holds an Estate-level AMDAL, tenants typically only need to prepare a UKL-UPL.
- SPPL — a statement of commitment to environmental management for low-risk businesses, without an in-depth technical study.
A common mistake is assuming the risk category without going through the official Amdalnet screening — this leads to rejection at the final stage and forces the whole process to restart.
Legal Basis and the 2026 OSS-RBA-Amdalnet Integration
The core legal foundation remains Law 32/2009 on Environmental Protection and Management, amended by the Job Creation Law (Articles 82A-82C) and detailed technically through PP 22/2021 and Ministerial Regulation (Permen LHK) 4/2021.
What changes in 2026: under Environment Minister Instruction No. 1/2025, manual submission of environmental documents is officially closed, and screening must now run online through Amdalnet, fully integrated with OSS-RBA (Risk Based Approach). The data-sync deadline is set for 1 June 2026 — businesses that fail to synchronize risk having their NIB automatically stalled in OSS because the environmental approval process cannot proceed.
Environmental Permit Flow Through OSS-RBA
In general, a new factory's environmental permitting follows this sequence within OSS-RBA:
- Register the business plan in OSS-RBA and obtain a risk-based NIB.
- Automatic screening in Amdalnet to determine the category: AMDAL, UKL-UPL, or SPPL.
- Preparation of the environmental document matching the category, assisted by a certified consultant if needed.
- Public consultation and review by the AMDAL Assessment Commission or DLH (for the AMDAL and UKL-UPL tracks).
- Issuance of the Environmental Approval, which becomes a prerequisite for the Building Approval (PBG).
Since OSS-RBA took effect, the government administration fee for location permits and the base OSS process is officially Rp0 — costs that do arise typically come from consultant fees for preparing documents, not state levies.
Timeline and Cost: AMDAL vs UKL-UPL
AMDAL typically takes 6-12 months because it involves multi-disciplinary field studies and an assessment commission hearing, with consultant fees that can reach hundreds of millions of rupiah depending on project complexity. UKL-UPL is far leaner, usually completed within 1-3 months at a significantly lower cost.
A key point for factory investors: choosing a site inside an industrial estate that already holds an Estate-level AMDAL can cut permitting cost and time by 60-70%, since tenants only need to prepare a UKL-UPL instead of a full AMDAL from scratch.
Penalties for Operating a Factory Without Environmental Approval
The Job Creation Law decriminalized many administrative environmental violations — a factory operating without Environmental Approval generally faces tiered administrative sanctions: written warnings, government-forced compliance, permit suspension, and ultimately permit revocation.
An exception applies to high-risk businesses with direct environmental impact or those handling hazardous materials — violations in this category can still carry criminal imprisonment and fines reaching billions of rupiah under Law 32/2009.
Tips to Speed Up Approval for a New Factory
Several practical steps have proven to speed up environmental approval for new factories:
- Run the Amdalnet screening from the feasibility-study stage, not after the building design is finalized.
- Choose an industrial estate that already holds an Estate-level AMDAL to avoid a full AMDAL process.
- Engage a certified AMDAL/UKL-UPL consultant so documents don't bounce back and forth through revisions.
- Prepare building technical data early — including wall and roof material specifications — since these are also assessed in the waste and energy management review.
How Building Design and Material Choices Affect Environmental Assessment
Both UKL-UPL and AMDAL documents assess how a factory's building design manages operational environmental aspects, such as thermal insulation, energy efficiency, and construction waste volume. The wall and roof materials chosen early on directly affect this assessment.
Using sandwich panels with PU, PIR, or rockwool cores generates far less construction waste than conventional brick and concrete, since the panels are factory-precision manufactured and assembled on-site with a bolt-together method. This directly supports the waste-efficiency criteria commonly reviewed in a UKL-UPL study.
A modular sandwich-panel construction approach also shortens the build timeline, narrowing the window between Environmental Approval issuance and the factory reaching operational status — a critical factor for investors chasing production targets in new industrial estates.
FAQ
What is the difference between environmental approval and PBG for a new factory?
Environmental Approval evaluates a business's impact on the environment and must be issued first, while the Building Approval (PBG) assesses the technical feasibility of the construction itself. PBG generally cannot be issued until Environmental Approval is complete.
Does a small factory inside an industrial estate still need a full AMDAL?
Not necessarily. If the industrial estate already holds an Estate-level AMDAL, a new tenant typically only needs to prepare a UKL-UPL or even an SPPL, depending on the risk screening result in Amdalnet — a full AMDAL is not automatically required.
How long does the AMDAL process usually take for a factory?
On average 6-12 months, depending on study complexity, the number of public consultation sessions, and how quickly document revisions are completed. UKL-UPL is much faster, typically just 1-3 months.
