I joined with this University as academia in 1999. I am a member of Analytical Chemistry Division in the Department of Chemistry, Universitas Indonesia.  So, I am a lecturer in the area of Analytical Chemistry, Environmental Chemistry and Quality Control and Quality Assurance for Laboratory Data.

My research experiences were started in 1996 to year of 2000 in the area of modifying hydrophobic polymer such as polypropylene and polyethylene fibers and thin film to become a  hydrophilic one that have functional characteristic as ion exchanger.  This modification were conducted by means of irradiation technique and chemical oxidation using ozone to initiate radical polymerization which well-known as graft copolymerization technique.

In the second stage of my research experiences within 2002-2007 I have some experiences on the study on sediment characterization focused on the release of phosphate from intact sediment cores and slurry sediments in the context of eutrophication in aquatic ecosystem. With this project we studied phosphate speciation between organic and inorganic phosphate released from sediment as well as phosphate compounds stability during short and long term storage time using Flow Injection Analysis system.  We found that the amount of organic phosphate species was quite significant detected present in the system and should be becoming compounds of interest besides inorganic phosphate which was previously considered to be the only phosphate species which involved in the problem of eutrophication.

Currently, we continue to study phosphate quantification by using diffusive gradient in thin film technique by developing the binding agent as well as ion imprinted polymer. Some electrochemistry detection of phosphate was also developed using potentiometric method. Some studies on development of super absorbent for slow release phosphate has also been conducted by means of irradiation technique using gamma rays as well as chemical oxidation. The other side of my research is now in the area of environmental monitoring for air quality for gas pollutant and particulate that contain heavy metals.

Besides doing research and teaching academics I also doing my professional duty as assessor for National Accreditation Committee (KAN) for Laboratory Technical Competency through ISO 17025 over a number variety of national laboratory both general chemical lab and environmental laboratories for the last ten years.
