Analysis of Job Risk in Manufacturing the Concrete Brick by Using Hazard Identification, Risk Assessment, and Risk Control (Hirarc) Method

Abstract

Global industrialization leads to fiercer competition. To survive in competition, companies must optimize their resources and produce qualified products while reducing work accidents. Work accidents could occur because people are less warned or demonstrate careless actions while doing their job. In the industry of concrete bricks, some still use manual and some already use the machine. To reduce risk and injury in the workplace, a quality OSH is needed to reduce the chance of work accidents. This research aims to identify the risks from the hazards involved in the production process in Pusat Inovasi Material Vulkanis Merapi UII. The research data of this research is primary data, which is using literature review and field study, and secondary data, which is using AS/NZS 4360 and ISO 31000. The instruments of this research are observation sheets and interview sheets. The methods to collect data in this research are observation, interview, and literature study. The type of research used in this research is qualitative descriptive using the HIRARC method. The result of this research is From Hazard Identification, which reveals that there are several hazards of work-related concrete brickmaking. The hazards are getting sand by stooping, carrying out the bucket of sand, the bucket does not have rubber on it, a wet area close to the electric source, carrying out the sack of cement, clamping, slipping, carrying up while stooping, and carry up the concrete brick. Risk Assessment before risk control exposes the absence of extreme levels of risk, 54% high level of risk, 38% moderate level of risk, and 8% low level of risk. From Risk Control, several activities were identified to reduce the risk that may cause work accidents. The activities are using a long shovel, using a cart, safety gloves, and an isolation electric source, cart, clear the workplace, making a pipe from the mixer into a Mold, and squatting while lifting the concrete brick. This research concludes that the method of HIRARC can be used to identify hazards, identify risks and their levels, and finally determine activities to control the risks.
