1. Regulation of the Minister of Health
No 492/MENKES/PER/IV/2010
Requirements for Quality of Drinking Water
2. Government Regulation of Republic Indonesia
Number. 82 of 2001 Concerning Water Quality Management and
Water Pollution Control
3. Regulation of the Minister of Environmental Affairs of Republic of
Indonesia Number 5 Year 2014 About Quality of Waste Water
4. Regulation of The Minister Of Environment And Forestry

16. Future Plan
Participate in the ILC  2017 (Euramet.QM-S11 Elements in River Water)
Strengthen and expand the technical measurement capability of some parameters therefore we can provide wider range of services.
Low expertise in measurement capability especially for anion. We have just started to learn and still can not provide the assigned value.
Provide testing laboratory needed for oil/fat and
detergent measurement.
Coordination with other institutions that also concern with the measurement of water quality.
Procure some instruments for the production and characterization of certified reference material.

17. Future Plan New building for CRM laboratory in Serpong (2018)
Support for provide all CRM
Accreditation for ISO 17034: 2016

18. Expected Cooperation
Reference value for proficiency testing with another NMI
Bilateral comparison
Attachment training for technical aspect, i.e anion analysis, organic parameters analysis
