Main task of chemical Metrology Laboratory to disseminate traceability and make sure quality assurance of measurement in Indonesia All activities on research and Proficiency Testing conducted by Chemical Metrology Laboratory support the implementation of government regulation

Regulations Related to Clean Water and Waste Water 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 Republic of Indonesia Number: P.68 / Menlhk / Setjen / Kum.1 / 8/2016 About Domestic Waste Quality Standards

Measurement Capability of RCM-LIPI Regulations: Regulation of the Minister of Health No 492/MENKES/PER/IV/2010 Requirements for Quality of Drinking Water No Parameter Unit Maximum Limit 1. Parameters that have direct affect to the health   Microbiology E-coli Total per 100 ml of sample 2. Total bacteria of coliform Inorganic Arsenic mg/l 0.01 2. Fluoride 1.5 3.

Measurement Capability of RCM-LIPI 2. Parameters that have indirect effect to the health   Physical parameters 1. Odor odorless 2. Colour TCU 15 3. Total dissolved solid (TDS) mg/l 500 4. Turbidity NTU 5 5. Taste 6. Temperature oC Air temperature ±3 Chemical parameters 1. Aluminum 2. Iron 3. Hardness 4. Chloride 5. Manganese 6. pH 6.5-8.5 7. Zinc 3 8. Sulphate 250 9. Copper 2 10. Ammonia 1.5

Measurement Capability of RCM-LIPI Additional Parameter Pesticide: Lindane, Heptachlor, Dieldrin Electrolytic conductivity

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.

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

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