Depok, August 13, 2025 – The Faculty of Public Health, Universitas Indonesia (FPH UI), through the Center for Applied Occupational Safety and Health Studies (PKTK3) of LPPM FPH UI, in collaboration with the Public Health Innovation and Research Laboratory (PHIR-Lab) UI, officially launched a research initiative and conducted a trial measurement of chrysotile dust in asbestos products that have been used by the community for more than three decades. This initiative represents FPH UI’s contribution in supporting the implementation of the principle of Safe and Responsible Use of Chrysotile (SRUC) while ensuring the protection of public health from potential exposure to chrysotile fibers.
The research, led by Prof. Doni Hikmat Ramdhan, S.K.M., M.K.K.K., Ph.D., and Prof. Dr. Ir. Sjahrul Meizar Nasri, M.Sc., Professors at the Department of Occupational Health and Safety, FPH UI, is funded by the Fiber Cement Manufacturing Association (FICMA). The main objective is to evaluate the quality and safety of corrugated cement sheet products after 30–40 years of use. Through laboratory experimental testing, FPH UI seeks to ensure that the strength of the product’s material bonds is sufficient to prevent the release of chrysotile fibers that could pose an inhalation risk to users.
In the trial, the research team prepared an experimental booth measuring 3 x 3 x 3 meters with a special ventilation system. Used asbestos products collected from the community were ground and blown with an air blower to generate fine dust. Dust samples were then collected using air sampling equipment over 3.5 hours at various height levels. The samples were subsequently analyzed in the laboratory using PCM methods and the NIOSH 7400 standard to determine chrysotile fiber concentrations in the air.
“The results of this research are expected to provide scientific evidence regarding airborne chrysotile fiber concentrations, whether they remain below or exceed the Threshold Limit Value (TLV) of 0.1 f/cc. If results indicate levels below the TLV, it can be concluded that the products meet quality standards and are safe to use throughout their service life,” explained Prof. Doni.
The official launch of this research was attended by various stakeholders, including the Head of LPPKM FPH UI, the Head of the Department of Occupational Health and Safety at FPH UI, and representatives from FICMA. Also present were officials from the Center for Standardization and Industrial Service for Chemistry, Pharmacy, and Packaging, namely Evana Yuanita and Agustina Arianita. From local government, representatives from the Housing and Settlement Office of Depok City and the Environmental and Sanitation Office of Depok City also attended.
In addition, representatives from the Ministry of Industry were present, including Dr. Putu Nadi Astuti (Director of the Cement, Ceramic, and Non-Metallic Mineral Processing Industry), Mr. Agust Juvenly, and Ms. Regina. Their presence reflected cross-sector collaboration in ensuring safe industrial product standards while protecting public health.
Through this initiative, FPH UI reaffirms its commitment as an academic institution actively engaged in evidence-based research to support public health and safety. This research also strengthens FPH UI’s contribution to addressing occupational health issues while supporting the adoption of safer industrial standards in Indonesia. (wrk)
