Indonesian Noise Measurement Standards: KepMen LH 48/1996 & SNI Standards

Indonesian Noise Regulatory Framework

Indonesia's noise regulations operate under the national environmental protection framework. The primary noise standard KepMen LH 48/1996 remains the reference for ambient noise limits, while newer government regulations address the broader environmental assessment process. Understanding the interaction between national standards and local enforcement is essential for compliance.

KepMen LH No. 48/MENLH/11/1996 — Baku Tingkat Kebisingan

The Ministerial Decree on Noise Quality Standards specifies ambient noise limits by land use designation:

• Residential (Perumahan dan Pemukiman): 55 dBA
• Commercial and Trade (Perdagangan dan Jasa): 70 dBA
• Offices and Government (Perkantoran dan Perdagangan): 65 dBA
• Industrial (Industri): 70 dBA
• Recreation (Rekreasi): 70 dBA
• Hospitals (Rumah Sakit): 55 dBA
• Schools (Sekolah): 55 dBA
• Places of Worship (Tempat Ibadah): 55 dBA

Measurements use LAeq over representative periods. The SonaVyx SPL meter provides continuous A-weighted Leq monitoring for direct comparison to these limits.

AMDAL (Environmental Impact Assessment)

PP No. 22/2021 on Environmental Protection requires AMDAL for prescribed projects. The noise component of an AMDAL typically includes:

• Baseline noise survey at representative receptor locations
• Prediction of noise levels during construction and operation
• Assessment of compliance with KepMen LH 48/1996 limits
• Noise mitigation measures (Rencana Pengelolaan Lingkungan - RKL)
• Monitoring programme (Rencana Pemantauan Lingkungan - RPL)

Use the SonaVyx noise monitor for extended baseline surveys required by AMDAL consultants.

SNI Standards for Acoustic Measurement

Indonesian National Standards (SNI) relevant to noise measurement:

• SNI 7231:2009: Measurement procedure for community noise
• SNI IEC 61672-1:2013: Sound level meters (adoption of IEC 61672-1)
• SNI 03-6386:2000: Sound insulation specifications for buildings
• SNI 03-6197:2000: Energy conservation in buildings (includes HVAC noise criteria)

Workplace Noise Regulations

Occupational noise is regulated by the Ministry of Manpower through Permenaker No. 5/2018 on Occupational Safety and Health:

• Noise exposure limit: 85 dBA for 8 hours
• Maximum exposure at 91 dBA: 2 hours; at 97 dBA: 30 minutes
• Engineering controls required when feasible
• Hearing conservation programme for exposed workers

The SonaVyx noise dose calculator supports Indonesian workplace exposure assessment.

Measurement Procedures

1. Use sound level meter meeting SNI IEC 61672-1 requirements (Class 2 minimum)
2. For environmental assessment, measure at receiver location, 1.2-1.5m height
3. Measure LAeq for minimum 10 minutes for steady sources (SNI 7231:2009)
4. For 24-hour surveys, compute daytime and nighttime LAeq separately
5. Note: Indonesia does not have formal day/night periods in KepMen 48/1996 — single limit applies
6. Calibrate equipment before and after measurement; document with Berita Acara (official record)

Practical Tips for Indonesian Measurements

• Call to prayer (adzan) from mosques occurs 5 times daily and is generally exempt from noise regulations — note timing in measurement reports
• Traffic noise is the dominant source in most Indonesian cities — Jakarta traffic patterns require careful timing of baseline measurements
• AMDAL consultants are registered with MENLHK — ensure your measurement report meets AMDAL Ketua Tim requirements
• Provincial BLH enforcement varies widely — Jakarta and Surabaya have more active monitoring than rural areas
• Construction noise complaints are increasing in urban areas — document compliance early to avoid delays

How SonaVyx Meets Indonesian Requirements

SonaVyx provides measurement tools aligned with Indonesian standards. The SPL meter measures A-weighted Leq per SNI IEC 61672-1 for KepMen 48/1996 compliance checking. The noise monitor supports extended surveys for AMDAL environmental impact assessments. The noise dose calculator implements occupational exposure limits per Permenaker No. 5/2018. The RT60 tool supports building acoustic verification per SNI 03-6386. For building acoustic design, visit AcousPlan noise calculators. Start learning with our learning modules.
