Abstract

PT. Kilang Padi Mutiara Refinery is a company engaged in rice production that produces rice, groats, and bran. The main product of this factory is rice. It can be seen in storage warehouse activities that they still experience problems with poor product placement due to irregular distances between placement and delivery areas caused by the preparation of products that are not based on inventory so that the products in the warehouse become narrower and seem messy, this triggers the accumulation of excess products. to damage the finished product packaging. Based on the existing problems, in this study, planning for layout improvements using the shared storage method was carried out to increase the effectiveness of the distance between doors to the storage area and better product placement. the steps of re-planning using the shared storage method begin by knowing the warehouse area, warehouse capacity, and other warehouse data, as well as collecting data by determining space requirements, determining space allowances, and the distance of the entrance to the storage area. From the data processing, the distance becomes more regular and can be known every distance. Based on the comparison of the initial layout and the proposal, it is known that the distance in the initial layout is 719.56 meters, while for the proposed layout using the shared storage method, the results are 593.33 meters with 13 product areas, with this loading and unloading activities become better and more effective.

Abstract

U.D. Keripik Mustika is a small and medium enterprise (SME) that processes yam raw materials into special snacks in great demand for consumption and souvenirs. According to observations, the worker experienced pain complaints during frying in the shoulder area, arms, back, waist, hands, and feet. The complaint experienced by this worker was due to the worker's posture that had to stand and bend slightly with the position of the hands continuously mixing for 7 hours a day and done manually repeatedly over long periods. This is if left, then the worker will suffer musculoskeletal disorders (MSDs). The research was conducted using the WERA method (Workplace Ergonomic Risk Assessment), which explains the development of ergonomic risk assessment at the workplace to detect physical risk factors associated with musculoskeletal disorders (MSDs). The spread of the Nordic Body Map questionnaire on frying workers showed pain complaints from an unergonomic working posture. The study results were obtained from Employee 1, with a physical indicator score of 39 (Medium), and Employee 2, with a physical indicator score of 37 (Medium). Therefore, there is a need for improvement of the work facilities or the worker's posture. Based on the assessment results, the researchers suggested additional facilities for workers to design standing aids that reduce pain in the leg muscles and complaints of Musculoskeletal Disorders (MSDs).

Abstract

PT Semen Padang is a cement manufacturer. According to preliminary observations, the cement packing process, which is done at the Packing Plant Indarung unit, is the last step of the cement production process. Due to the sideways and bowed body positions, cement bagging is performed manually with a less ergonomic working position. This is performed continuously, causing workers complaints of musculoskeletal disorders. The results of distributing the Nordic Body Map questionnaire to employees indicate that many operators experience pain due to their work positions. Based on these findings, the RULA method was used to analyze work posture, yielding a group A posture score of 7, a group B posture score of 4, and a final RULA assessment score of 7. The OWAS method assessment, meanwhile, earned a score code of 2141 and was categorized as a level 3 risk. The results of the risk assessment using the RULA method yield a score of 7, indicating that the operator's work attitude needs to change immediately, whereas the results of the assessment using the OWAS method yield a score of 3, indicating that work posture has a very significant impact on tension and needs to be corrected as soon as possible. On the basis of the results of these assessments, a recommendation was made to design a trolley work facility that can be utilized to reduce the risk of MSDs for cement packaging operators

Abstract

PT. Ika Bina Agro Wisesa (IBAS) is a company that produces products in the form of crude oil or CPO (Crude Palm Oil). The company sets a minimum production target of FFB that must be processed to reach 30 tons in one boiling with a minimum production target of 600 tons/day. The company is required to increase productivity. The problem so far is that the company has never measured the productivity of the production process, which will then affect the achievement of production targets. Measurement of productivity is critical because the measursizeoductivity can determine whether the company meets productivity targets for production or not. Therefore, it is necessary to measure productivity to assess the value of productivity and efforts to increase productivity in CPO production and how to increase productivity in CPO production and efforts to increase productivity using the Objective Matrix (OMAX) method at PT. Ika Bina Agro Wisesa. Analysis of productivity using the OMAX method, ratio 3 (labor productivity) and ratio 4 (machine productivity) has a very high percentage of poor performance, which means that ratio and 4 have an insufficient level of productivity. Unlike the case with the achievement of productivity ratio 1 (productivity of raw materials) and ratio 2 (productivity of working hours) wh, ich shows a low percentage of poor performance, which means that the productivity level of ratio one and ratio 2 has a better productivity level than ratio three and ratio 4 Analysis The results of the productivity index in the company decreased and increased for each month, in November it experienced a decrease of -79.49, while in December it experienced a significant increase in the amount of 595.02 and January at 69.98. in February decreased to -23.63. Furthermore, productivity in March - September 2021 was unstable, with an increase and dropped for July, a decrease of -0.64 and, a slight increase in August of 0.28.

Abstract

The workload workers face can influence their performance and productivity physically and subjectively. Physical workload includes factors such as environmental temperature, noise, and lighting, which affect the worker's health, while subjective workload encompasses time pressure, effort, and stress experienced by the worker. One form of workload that can impact employees is the shift work system, which often leads to physical and psychological fatigue if not correctly managed. This Company, which implements a shift work system in its rubber processing factory, faces employee productivity and health challenges. This study aims to evaluate employees' workload using the NASA-TLX method, which measures six workload dimensions: Mental Demand, Physical Demand, Temporal Demand, Performance, Effort, and Frustration Level. The results of this study are expected to provide insights into the factors affecting employees' workload and offer recommendations for improving the work system to enhance productivity and team member well-being within the Company.

Abstract

PT. Sisirau Palm Oil Mill Company is engaged in the production of crude palm oil (CPO) and kernel. In its production processes, the company continuously operates heavy machinery around the clock. These machines generate high noise levels, potentially causing both auditory (hearing-related) and non?auditory (communication, physiological, psychological, and work?productivity) disturbances among workers. This study aims to map the noise levels and analyse their impact on auditory and non?auditory disorders among workers at the production workstations of PT. Sisirau’s palm oil mill. Measurements were taken at 74 points across five production workstations: the kernel station, boiler station, engine room, clarification station, and press station. Using a Sound Level Meter, noise measurements were converted into equivalent continuous sound levels, followed by regression analysis employing the t?test to determine the relationship between noise exposure and worker disturbances. The results show that most measurement points at the production workstations exceeded the established Threshold Limit Value (TLV), with an average noise level of 98?dB. This indicates that noise levels in production areas are very high and require immediate reduction measures. Moreover, the statistical analysis revealed a significant correlation between noise levels and both auditory and non?auditory disturbances among workers (P-value = 0.002 0.05). In other words, as noise exposure increases, so does the risk of hearing impairment, communication problems, physiological and psychological effects, and reduced work productivity. These findings underscore the urgent need for noise control efforts, improvements to the working environment, and the implementation of more effective and consistent occupational health and safety policies to safeguard the health and safety of workers at PT. Sisirau’s palm oil mill.
