WATER BASED ACTIVE FIRE PROTECTION SYSTEM IN OFFICE ENVIRONMENTS AND BUILDINGS

Abstract

This study is part of previous research. The purpose of the study was to find the cause of the inability of the environment and buildings to protect against fire hazards and to plan an appropriate fire protection system. The object of the study was the Jayapura Regent's Office Complex located in Sentani City. At the research locus, no water-based Active Fire Protection system equipment was found, such as a manual detection system (Yard Hydrant and Building Hydrant), an automatic detection system (sprinkler, shaft or vertical corridor for placing vertical pipes) and City Hydrants along Arterial roads or around the Office Complex.
The research method uses a quantitative method with a calculation tool SNI 03-1735-2000 concerning Procedures for Planning Building Access and Environmental Access for Preventing Fire Hazards in Buildings. The researcher calculated the land area (22.25 Ha) and the floor area of the building (44,403 M2) using the ArcGIS Pro 2.8 application. Next, the researcher will calculate the number of Yard Hydrants and raw water capacity needed by estimating the travel time of the Fire Engine to the fire location of 45 minutes. The number of Yard Hydrants obtained is 45 Sets which will be distributed to 8 Zones and placed at the 4 corners of the outer yard of the building and must be accessible by the Fire Engine.
The volume of raw water for 45 Sets of Hydrants is 2,484 m3 (water stock). Based on the 2019 fire incident, where the fire engulfed the building floor covering an area of 8,744 m2 (20%), it can be estimated that the amount of raw water to be provided is 25% of the total reserve water (2,484 m3) which is 621 m3 ~ 15 Sets of Hydrants, with the provision that 15 of the 45 sets of Hydrants must work effectively simultaneously according to the planned pressure for 45 minutes.
