Abstract

Solar Power Plants (PLTS) are electrical power generators that convert solar energy into electrical power. One of the companies engaged in electricity generation is PT. Brilliant Renewable Infrastructure. The problem that often occurs in PLTS is zero power in the combiner box. Zero power is a problem that often occurs which causes the energy produced by the PV module to not be optimal. The aim of this research is to analyze the causes of zero power in the combiner box. One way to find out the factors causing zero waste is to use a Problem Tree. Problem Tree is a methodology/technique used to identify the reasons for a problem. The results showed that the factors causing zero power in the combiner box were three causes, namely the cable gland installation was not tight enough, the DC cable was bitten by rats and the strings were not functioning. The impact of these 3 types of damage can cause zero power so that no electrical voltage is generated

Abstract

As a company that operates in the field of solar power system project development, of course there are many risks at PT Surya Utama Nuansa (SUN Energy), such as during installation and during maintenance. Therefore, employees are required to use personal protective equipment, but based on observations, potential dangers were found in the form of piles of damaged inverters or other materials in random locations and workers lifting solar panels alone, as well as scattered electrical cables. The aim of this research is to provide a solution to reduce the risk of work accidents. The method used in this research is the HAZOP (Hazard and Operability Study) method. Based on the results of the identification and assessment of potential hazards that have been carried out, there are 5 potential hazards, namely a moderate risk level of 27%, a high risk level of 20%, and an extreme risk level of 53%. And it is known that there is a 40% potential hazard in the work attitude classification. 20% on work procedure classification, and 40% on workplace classification. This shows that potential hazards in workplace classification require more attention in efforts to prevent work accidents. It is hoped that this research will implement health and safety at the PT project site. PP (Persero) has been repaired so that it can minimize the occurrence of work accidents while carrying out activities on the site.

Abstract

Quality is an important indicator of a product. PT. XYZ is a company engaged in the field of construction services, Engineering Procurement Construction (EPC), and Investment which is currently expanding its terminal and facilities at Lombok International Airport (BIL). Results Based on the inspection, various Defects were found in the steel such as cracked welded joints, peeling steel paint, thin paint thickness. This will have an impact if the steel roof truss structure is Defective, it will endanger the collapse of the building and the safety of visitors at BIL. Based on this, an analysis is carried out on the work of the steel pipe roof truss structure that occurs in the terminal expansion project and its supporting facilities so that recommendations for improvement can be made. This research was conducted using the Six Sigma method. The result of the research is that the main factor that causes failure is the steel pipe being stepped on during the installation of electrical installations. The proposed improvement to overcome these Defects is to provide ongoing counseling and training programs on worker compliance in carrying out work by the Standard Operating Procedures available in all work processes. It is hoped that by conducting this research, the company can better maintain quality so that the risk of building collapse and safety from incidents cannot be avoided.

Abstract

The K3 management system is part of the company management system in the context of risk control to minimize dangers in the workplace. Work accidents can cause losses in time, wealth, property and lives. Accidents have causes so it is necessary to control and repair work places, tools and processes. This research was conducted using the HIRARC (Hazard Identification Risk Assessment and Risk Control) method to identify hazards that can occur in each job. In the preparation of HIRARC it is divided into three stages, where the first stage is hazard identification, then risk assessment, and the next stage is the risk control stage. The result of hazard identification is that there are several potential hazards in the work place and attitude. After carrying out a risk assessment, the risk level obtained before controlling the shootcreet work process was carried out, namely very high risk while those with medium risk tended to be high and medium tended to be low. After control was carried out, it was found that the risk value had decreased to predominantly green or low. Control of potential hazards in the shootcreet work area is proposed in the form of an appeal to complete PPE, use APK properly and an appeal to pay more attention to occupational safety and health in every work process.

Abstract

XYZ is a State-Owned Enterprise (BUMN) engaged in the construction sector. One of the infrastructures currently being built by PT. XYZ is the Construction of the Lombok Peaker PLTMGU Jetty in Mataram. Based on the results of observations, it was found that there was a risk of danger to welding workers that could cause work-related illnesses in spun pile welding workers or piles, so further analysis is needed. This study aims to analyze work postures and complaints and provide suggestions for welding work at PT. XYZ on the Lombok Peaker PLTMGU jetty construction project. The methods used are the Rapid Entire Body Assessment (REBA), Nordic Body Map (NBM) and tree diagram methods. The results of the study obtained REBA on the first, second and fourth welders were at a high risk level. The results of the Nordic body map score for welder 1 are in the moderate category, meaning that corrective action may be needed. Several workers filled out complaints of pain in several parts of the body. The proposed improvements are adequate rest, adjusting the height of the pile to be welded to the height of the welder, the welder welding with a more upright body, and providing a chair for the welder. It is expected that this research can minimize the risk of work-related illness in welding work at PT. XYZ on the Lombok Peaker PLTMGU jetty construction project.
