Safety of buildings and their environment against fire hazards is a must in the design of building reliability. Decision-making on the design of hazard assessment and prevention systems in buildings is very necessary, to determine the level of reliability. The purpose of this study is to make a decision-making analysis for the assessment of building reliability systems in fire prevention and environmental safety. Decision-making analysis of building reliability assessment systems for fire prevention and environmental safety using the Fuzzy Analytical Hierarchy Process (Fuzzy AHP) method. The main criteria used are the prevention system and prevention management. The main criteria use sub-criteria in the form of prevention, limitation, and extinguishing of fire hazards. Assessment of the system design is carried out by questionnaires to expert respondents who understand the problem of fire. The results of the research on building reliability system weight assessment show that the weight on the Fire Prevention System is 59% and the weight on the Prevention Management is 41%. In more detail the weights of importance on the design criteria of Prevention Management and Systems are Inspection and maintenance 32%, Coaching and training 26%, Emergency planning 21%, and Housekeeping 21%. The results of the final assessment on the reliability value of the building are 94.06%, meaning that the building reliability system is in the "Less Reliable" category for fire prevention and environmental safety, so it is necessary to make several improvements and recommendations to increase the reliability of the building on environmental safety.
