Introduction: Major fire accident involving static electricity still become serious latent problem (1), this similar to PT XYZ which still experience serious fire incident caused by static electric. This study intend to do the analysis of the adequacy of the protection to fire and explosion caused by electric static at hazardous process at paint production. Methode: This analysis is using bow tie analysis and risk assasment matrix, Bow Tie analysis describe and visualize the correlation between what caused rsik, top event, and control that used to anticipate the incident happened and also mitigation barrier that can prevent from further escalation, then risk assasment matrix give semiquantitative risk calculation to reflect the level of risk. From this determination than we decide recommended control base on best practice and standard which is relevant. Results: From this study we found that at paint manufacture PT XYZ only 22% of protection is adequate to prevent from electrostatic, than 7% of threat still categorized very high , 40% is high risk , and 31% is moderate risk. Base on best practice and literature study than we recommend some of action that need to be taken to improve the barrier. Conclution: The recommendation basicly is to improve the visibility of grounding performance using lam indicator, improve visibility of flammable atmosphere using LEL detection , to reduce electrostatic discharge during process by control the liquid flow, to improve charge relaxation by selecting the tools properly, and to prevent fire during cleaning by inerting and reduce the solvent mist, also to increase the conductivity of non conductive solvent by adding conductivity agent
H2S is dangerous compound that colorless and has smell like rotten egg. One of this compound source is produced from decomposition process in landfill. The most sensitive body system when exposed to H2S is respiratory system. This study aims to analyze the effect of H2S intake to respiratory symptoms at people living around the Cipayung Landfill. This study design uses cross sectional. Data collection was carried out by interview by questionnaire and measure H2S ambient at 9 poimts locate aroundd community settlements. The result were found intake of H2S associated with respiratory symptoms (p value=0,012; OR=10,5; CI 95%=1,25-88,02). The result of multivariat analysis were found H2S intake influence respiratory symptoms after controlled by duration living variable (p value=0,026; OR=6,78; CI 95%= 1,612-64,572). It needs to measure routine H2S ambient and ensure that concentration was safe as well as proper management efforts from City Government of Depok, Cipayung Landfill and related stakeholders in order to reduce the health risk problems to the people living around Cipayung landfill.
