Abstract

PT. XYZ is a company engaged in the field of fabrication, particularly in cutting. At PT. XYZ, there is currently no specific program to reduce workplace accidents. The cutting division at PT. XYZ frequently experiences workplace accidents. Therefore, the aim of this research is to reduce the potential for workplace accidents by using Job Safety Analysis. The data collection techniques employed are observation, interviews, and documentation. Data processing and analysis use the principles of Job Safety Analysis and Fishbone tools. Based on the research results, it was found that there are five hazard categories: extreme, high, moderate, and low. There is one hazard at the extreme level: being struck by chips from the cutting activity. The high level consists of one hazard: being struck by cutting blade fragments. The moderate level has one hazard: material not matching capacity. The low level includes three hazards: slipping, being struck by falling material, and being hit by sparks. The proposed prevention measure is elimination, where the source of workplace hazards in the cutting process is completely removed. The second step, substitution, involves replacing tools or materials with ones that meet the standards in the cutting process. The third step, engineering controls, includes installing warning signs. The fourth step, administrative controls, involves preparing safety meetings before starting work and close supervision. The fifth step is using appropriate personal protective equipment (PPE).

Abstract

In production and project management, a bottleneck is a disruption of one process in the process chain, so that its limited capacity reduces the capacity of the entire chain. One of the companies in Indonesia that operates in the agricultural industry and produces dried lemons is PT. Semesta Agro Indonesia. At PT. Semesta Agro Indonesia, frequent imbalances in production trajectories were detected. This happens because the dry lemon production line has a queue of material that blocks the production flow. This research was conducted to identify the causes of bottlenecks that occur in the dry lemon production process at PT. Semesta Agro Indonesia. The research results showed that lemon production experienced a bottleneck at the drying and slicing workstations, with a total time in each department of 15,529 seconds and 7,778 seconds, and 5 unnecessary activities were found with a total time of 1844 seconds (30 minutes and 44 seconds). Once an activity is found that does not add value, it is necessary to eliminate it in the process. After eliminating several non-value-added activities, the cycle time, which was previously at 35,679, fell to 33,835 seconds, or a decrease of 30 minutes and 44 seconds

Abstract

The electricity distribution network is the backbone of energy supply from power plants to consumers. One important component of the distribution network is the arrester, which serves to protect equipment from sudden voltage surges, such as those caused by lightning strikes. Arresters are designed to withstand overvoltage and protect transformers and other sensitive components from damage. This research uses a case study method with a descriptive qualitative approach. Data were collected through interviews with technicians involved in network maintenance and field inspections of the condition of arresters in the distribution network of PT. PLN (Persero) UP3 Cikupa. The research findings indicate that several arresters in the distribution network of PT. PLN (Persero) UP3 Cikupa receive voltages that do not meet technical specifications, leading to voltage leakage. Based on the research results, it can be concluded that regular replacement of arresters is necessary to maintain the reliability of the electricity distribution network. Voltage leakage caused by discrepancies between incoming voltage and the technical specifications of the arresters has the potential to cause damage to network equipment, particularly transformers.

Abstract

This study aims to determine the working system of the Mitsubishi Fuso type 125Ps truck brakes using a brake test tool, namely the Axle Load Breaker Tester at the Cilegon City Transportation Agency. This study uses a direct experimental method using motor vehicle subjects, namely the Mitsubishi Fuso type 125Ps truck. There are 3 data taken, namely the foot brake on axle 1, the foot brake on axle 2 and the hand brake on axle 2. There is also total data on the overall test results which are used to decide whether the final result of the vehicle passes or fails the test and there is also data on the imbalance or deviation between the right and left wheels. There are 2 displays produced from this test, namely by using the existing formula and seeing the results directly on the monitor screen. The results of these two displays are slightly different, perhaps due to several factors including tolerance on the tool, lack of calibration on the tool and age factors on the tool. However, from the differences in these results, the data obtained shows that this vehicle has met the roadworthiness requirements in accordance with existing regulations. This periodic testing is carried out at least once every 6 months so that the braking system works optimally and does not cause accidents for the driver or others.
