Abstract

The purpose of this study is to identify the factors that cause workplace accidents and to develop a plan to address them. A lack of occupational health and safety, unsafe behavior, and unsafe and unhealthy working conditions have led to accidents during the production process of birthday candles at PD. Sinar Baruna Abadi. To prevent such incidents from recurring, it is necessary to implement controls through an accident prevention plan using the Job Safety Analysis (JSA) and HIRADC (Hazard Identification, Risk Assessment, and Determining Control) methods.The methodology consists of three stages: hazard identification through interviews and field observations, followed by risk assessment by analyzing the likelihood and severity of each potential hazard. The study identified 24 potential hazards in the birthday candle production process, categorized by high, medium, and low risk levels.Planning and control were carried out for five risks with varying values. A risk value of 8 involved activities such as pouring materials and removing candles from molds, with risks of burns and blistered hands. A risk value of 9 was associated with removing candles and dipping them into hot paraffin, posing risks of hand burns and respiratory issues. The highest risk (value 10) occurred during the candle dipping process in hot paraffin, with exposure to hot chemical substances that could cause severe burns.Control measures were focused on risks with values of 9 and 10, including the installation of turbine ventilators to reduce exposure to fumes and vapors.

Abstract

The rapid development of development programs in Indonesia, including in the industrial sector, has brought both positive and negative effects. One of the negative effects is environmental pollution, workplace accidents, and occupational diseases, which are caused by an imbalance between progress and the level of awareness regarding occupational safety and health. To ensure comfort and safety in the workplace, a strong work culture is essential. Various methods and tools are used to improve business quality and productivity. One of the most common approaches is the hierarchy of controls, which includes elimination, substitution, engineering controls, administrative controls, and the use of personal protective equipment (PPE).The leather industry company CV. Sinar Brahma Rasyid in Garut faces several occupational safety issues. A total of 33 workplace accidents occurred in 2021, 44 in 2022, and 59 in 2023. In response to these issues, the Job Safety Analysis (JSA) method and the hierarchy of controls were used to identify potential hazards and risks, followed by the implementation of control measures.The aim of this study is to identify the factors contributing to workplace accidents, assess risks, and provide recommendations for improvement in the production department of CV. Sinar Brahma Rasyid. The research findings indicate several causes of workplace accidents, such as employees not using PPE, carelessness, disorganized factory layout, and a lack of tools to assist in material handling.The risk assessment categorized the risks into two levels: low and medium. One example of a medium risk is a workplace accident that can result in serious injury. To reduce workplace accidents and occupational diseases, the study recommends ergonomic chair design, the addition of transport equipment, the use of hazard signs, machine operation training, and the implementation of PPE usage.

Abstract

This study aims to optimize the distribution routes at the MSME Cuankie HD Barokah Garut to improve operational efficiency. The MSME faces challenges in distribution management due to limited resources and suboptimal routing. To address this, the study applies the Capacitated Vehicle Routing Problem (CVRP) approach based on the Genetic Algorithm (GA). CVRP is used to consider vehicle capacity in delivery optimization, while GA is employed to determine optimal routes that minimize distance, time, and operational costs.Data were collected through observations and distance measurements using Google Maps. Before optimization, the total distribution distance reached 101.4 km with a travel time of 325 minutes and operational costs of Rp. 518,200. After optimization, the distribution routes became more efficient, with a total distance of 82.3 km, travel time of 277 minutes, and reduced operational costs of Rp. 471,300.The results show that the Genetic Algorithm significantly improved distribution efficiency by reducing travel distance, travel time, and operational costs. The implementation of GA proved effective in optimizing distribution routes for MSMEs with limited resources.

Abstract

PD. Jaya Rasa is a micro, small, and medium enterprise (MSME) in the food industry that produces makaroni cikruh. The issue faced is the fluctuating monthly production, which is inconsistent and fails to meet targets. Therefore, the objective of this study is to measure productivity and analyze improvements across several factors—such as labor, energy, raw materials, and machinery—that contribute to the decline in productivity, in order to utilize company resources more efficiently and effectively. This study uses the American Productivity Center (APC) method to determine productivity, profitability, and price improvement values by accounting for labor, raw materials, energy, and total inputs. To identify the root causes of productivity decline, a Fishbone Diagram is applied. The study finds that the highest productivity index was in energy at 106.367 percent during January, while the lowest was in labor at 91.864 percent in December. The proposed recommendations include monitoring the production process, conducting regular performance evaluation and skill training, and purchasing more modern packaging equipment, such as a sealing machine, to accelerate the packaging process.

Abstract

The main issue faced is how to minimize delays and avoid penalties in fuel distribution, which is characterized by dynamic conditions. This study aims to optimize the distribution routes of fuel oil (BBM) to gas stations (SPBU) using a genetic algorithm at the Tasikmalaya Fuel Terminal. The research adopts a descriptive quantitative approach. By applying the Capacitated Vehicle Routing Problem with Time Windows (CVRPTW) method, the genetic algorithm is expected to generate optimal solutions in terms of distance and time variables. The study focuses on several constraint variables, including operational costs, vehicle carrying capacity, vehicle utilization, and potential penalties. The collected data covers fuel demand, tank truck capacity, distances between the Tasikmalaya Fuel Terminal and SPBU, travel time, operational costs, loading and unloading times, tank truck specifications, and tank truck usage within one delivery period. The results indicate that implementing this model can reduce the risk of delivery delays. In the initial data, the tank truck with license plate Z9357TB was scheduled to deliver fuel to three different SPBU. At the final destination, however, a delay occurred: the truck arrived at SPBU 34.46.310 17.5 minutes late. After route optimization using the genetic algorithm by selecting the shortest route as the initial sequence for visiting SPBU, the delay was minimized to 0.0 minutes, meaning the final destination SPBU no longer experienced delays. In addition, this study provides recommendations to the company regarding the implementation of the route optimization model and identifies opportunities for further development to enhance the model’s effectiveness.
