Penelitian ini berupa analisis penyebab coal dust explosion accident di PLTU X tahun 2011 yang terjadi pada tanggal 14 Desember 2011 mengakibatkan kerugian yang berupa kerusakan coal feeder dan panel instrumen boiler, dan kerugian akibat terhentinya pembangkitan energi listrik selama masa perbaikannya. Penelitian dilakukan dengan pendekatan kualitatif untuk menganalisis data primer dan data sekunder untuk menganalisis penyebab langsung, penyebab tidak langsung dan penyebab dasar. Penyebab langsung adalah interaksi bahan, alat dan proses sehingga terpenuhinya 5 kriteria dust explosion pentagon dan menciptakan ledakan. Penyebab tidak langsung terdiri dari prilaku tidak aman dan kondisi tidak aman. Prilaku tidak aman yang dilakukan adalah mengoperasikan mill saat terjadi gangguan blocking, membuka damper cold air terlalu cepat sehingga menciptakan terpenuhinya 5 kriteria coal dust explosion diakibatkan oleh pengetahuan akan resiko coal dust explosion, tidak tersedianya SOP, pengaturan mode operasi yang belum sesuai, dan kerusakan damper cold air. Sedangkan kondisi tidak aman terdiri dari gangguan blocking, kerusakan peralatan, dan desain coal feeder. Penyebab dasar adalah komunikasi yang sulit antara operator dan kontraktor EPC, ketidakjelasan mengenai tanggung jawab perbaikan, kurangnya pengalaman personel, dan tidak ada pengawasan mengenai K3 operasi. Risk assessment khusus pengoperasian mill perlu dilaksanakan untuk mendapatkan langkah-langkah pencegahan insiden coal dust explosion yang paling tepat.
This study analyzes the causes of a coal dust explosion accident at Steam Power Plant ?X? in 2011 which occurred on December 14, 2011 caused in losses such as damage to the instrument panel coal boiler feeder, and losses due to interruption of electric energy generation during repairs. The study was conducted with a qualitative approach to analyze primary data and secondary data to analyze the direct cause, indirect cause and basic cause. The direct cause is the interaction of materials, tools and processes that fulfill 5 criteria and creating a dust explosion pentagon explosion. Indirect causes consist of unsafe actions and unsafe conditions. Unsafe action consisted of operate mill during disturbances blocking, open the damper cold air too fast, creating the five criteria of coal dust explosion caused by the knowledge of the risks of coal dust explosion, unavailability of SOP, the setting is not appropriate mode of operation, and damage damper cold air. While unsafe conditions consisted of interference blocking, damage to equipment, and design of coal feeder. The basic cause consisted of a difficult communication between the operator and EPC contractors, uncertainty regarding the repair responsibilities, lack of personnel experience, and there is no oversight of the safety operation. Risk assessment should be carried out special operation of the mill to get the preventive measures coal dust explosion incidents are most appropriate.
This study assess the consequences of the chemical release from the pressurized Liquefied Petroleum Gas (LPG) storage tank at PT. LMI. This study is kuantitative. Simulation of release using ALOHA (Areal Locations of Hazardous Athmospheres) software based on primary and secondary datas on the normal operation. ALOHA give result in a distance range of dispersion, fire and explosion. Each distance range is classified into three categories: red, orange and yellow based on the level of severity. These study's result is indicate that schools, medical clinic, factories, and homes around PT. LMI being the high-risk population affected by the release of chemicals from the LPG storage tank.
The petrochemical industry is a high-risk sector for fire and explosion hazards due to the involvement of flammable and toxic substances, as well as operating conditions at high temperatures and pressures. This study is a semi-quantitative descriptive research aimed at classifying hazardous areas in the production process based on the API RP 500 standard and determining the level of fire and explosion risk in the ammonia gas production process using the Dow’s Fire and Explosion Index (DF&EI) method. The methodological approach includes the identification of hazardous chemicals, hazard level assessment using DF&EI, analysis of loss estimation and exposure radius, and assessment of ammonia gas dispersion and process explosion using the ALOHA software. The analysis results show that Plant 1A has a DF&EI index categorized as severe, with an exposure radius of 223.78 meters and an actual MPPD of IDR 154 billion in the ammonia converter unit, and categorized as light, with an exposure radius of 45.78 meters and an actual MPPD of IDR 47 billion in the urea reactor unit. The hazardous area classification indicates the presence of Class I, Division 2 classified zones in several parts of the production process close to the ammonia vapor and natural gas release sources. The worst-case scenario shows a significant impact due to an explosion from the ammonia converter unit with a blast radius of up to 269 meters causing window glass breakage, and ammonia gas dispersion from the urea reactor spreading up to 10 kilometers, potentially causing respiratory issues.

As a general facility CNG Station is located in a densely populated and dense activity area, therefore CNG Station failure will have considerable consequences for operators, customers and communities around SPBG. This research is conducted using descriptive and quantitative analytic method to calculate the level of individual and social risk which resulted by frequency calculation using event tree analysis and consequence using ALOHA software. The data used in this study using primary data by field measurement and interviews as well as secondary data from the literature and company. This research explains the steps of fire and explosion risk analysis in CNG Station and followed by some recommendation to control fire and explosion risk in CNG Station based on risk analysis.

The focus of this thesis discuses about risk factors and the impact of fires and explosions that can occur from the operation of boilers in the PT X Food Industry. This research is a semi quantitative research using Dows Fire and Explosion Index calculation method and the ALOHA software version 5.4.7 which is superimposed with MARPLOT. The results of the study obtained a value of 111,62 with the classification of the risk level of Boiler fire and explosion hazard in the Intermediate category. The population affected by the fire and explosion was 615 workers with an estimated loss Rp. 879.872.821.672. PT. X can reduce the value of losses and prevent fires and explosions through the provision of adequate active and passive fire protection facilities, updating emergency response prosedures, simulatin, personnel training and upgrading the Boiler System to Automatic Boiler
