Abstract

Intisari— Lingkungan kerja fisik menjadi hal yang wajib diperhatikan untuk mewujudkan produktivitas pekerja dalam melaksanakan tugasnya. Faktor lingkungan kerja fisik adalah salah satu faktor eksternal yang dapat memengaruhi dalam kerja mental seseorang. Potensi timbulnya bahaya atau penyakit karena kerja dapat memengaruhi kesehatan karyawan dan hal ini sering muncul dari tempat bekerja. PT ABC merupakan salah satu perusahaan swasta nasional yang bergerak di bidang industri pengecoran logam pipa air mineral yang masih menggunakan bantuan tenaga manusia. Dalam pelaksanaan produksinya, PT ABC memiliki beberapa kondisi lingkungan yang kurang mendukung pekerjaan karyawan. Maka dari itu, dilakukan penelitian ini untuk menganalisis lingkungan kerja fisik khususnya faktor suhu dan kebisingan lingkungan pekerjaan dan memberikan rekomendasi agar pekerja dapat bekerja lebih aman dan nyaman sehingga tidak mempengaruhi produktivitas tenaga kerjanya. Pengumpulan data pengukuran lingkungan kerja fisik dilakukan dengan alat Envirometer 4in1 dan kemudian perhitungan faktor suhu dengan LTM5. Berdasarkan hasil pengolahan data dan analisis masalah, dapat disimpulkan bahwa hasil pengukuran suhu ruangan sebesar 30,5˚C hingga 32,4˚C pada waktu pagi dan sebesar 31,7˚C hingga 34,3˚C pada waktu siang. Sedangkan, pada hasil pengolahan data tingkat kebisingan didapatkan hasil sebesar 90,06 dB. Rekomendasi yang dapat dilakukan untuk memperbaiki lingkungan kerja pada faktor suhu yaitu menambahkan ventilasi, menyediakan blower di area kerja, menyediakan air minum bergaram natrium cukup, dan menanam tumbuhan di sekitar area ruangan sehingga terasa lebih sejuk. Sedangkan, pada faktor kebisingan yaitu dapat disediakan Alat Pelindung Diri (APD), memberikan penyuluhan K3 (Keselamatan dan Kesehatan Kerja), dan menyesuaikan jam kerja dengan waktu istirahat yang disarankan oleh KEMNAKER tahun 1999. Abstract— The physical work environment is something that must be considered to realize the productivity of workers in carrying out their duties. Factors of the physical work environment are one of the external factors that can influence in the mental work of workers. The potential for occupational hazards or illnesses can affect the health of employees and this often arises from the workplace. PT ABC is one of the national private companies engaged in the mineral water pipe metal casting industry which still uses the help of human labour. In the implementation of its production, PT ABC has several environmental conditions that do not support the work of employees. Therefore, this study was conducted to analyze the physical work environment, especially the temperature and noise factors of the work environment and provide recommendations so that workers can work more safely and comfortably, so that it does not affect the productivity of its workforce. Data collection of measurements of the physical work environment was carried out with the Envirometer 4in1 tool and then the calculation of the temperature factor with LTM5. Based on the results of data processing and problem analysis, it can be concluded that the results of room temperature measurements are 30.5° C to 32.4° C in the morning and by 31.7° C to 34.3° C in the afternoon. Meanwhile, in the results of data processing, the noise level obtained results of 90.06 dB. Recommendations that can be done to improve the work environment on the temperature factor are to add ventilation, provide a blower in the work area, provide enough sodium-rich drinking water, and plant plants around the room area so that it feels cooler. Meanwhile, the noise factor can be provided with Personal Protective Equipment (PPE), providing K3 (Occupational Safety and Health) counselling, and adjusting working hours to the rest time recommended by the Ministry of Manpower in 1999.

Abstract

In a highly competitive market, maintaining high product quality is essential for maintaining customer satisfaction and loyalty. Producers are famous in East Java and face the challenge of ensuring consistent quality products through strict production processes. Know that as easy products broken and soft, needy control of careful quality to meet hope consumers about freshness, texture, and quality in a way whole. Although traditional control methods often fail to overcome the production complex that causes a disabled product. This research proposes integrating Statistical Process Control (SPC), Ishikawa diagrams, and Interpretive Structural Modeling (ISM) to improve control quality. SPC makes it possible to monitor and control production processes in real-time, identify deviations, and repair deviations. However, the SPC limitations include a focus on quantitative data and post-incident detection problems. To overcome root problems, the Ishikawa diagram categorizes the reasons for potency as material, machine, method, power work, and environment. ISM prioritizes action repair based on impact and relationship. Approach This integrated approach provides comprehensive solutions to improve the quality of knowledge. In this study, the control process quality was evaluated using SPC, the cause of defects was identified using Ishikawa diagrams, and priority action repair was performed via ISM. Findings show that SPC directly effectively monitors process control, the Ishikawa diagram identifies main defects, and ISM prioritizes impactful action improvements, emphasizes excessive additions to subtraction materials, and improves health workers’ and mixing process material standards. Approach integrated possible identification of additional problems and improved the quality strategic makes a significant contribution to enhancing product quality knowledge.

Abstract

Good work environment conditions can affect the increase in worker productivity. One of the work environment factors that needs to be considered is distraction. Noise problems not only interfere with concentration but can also damage workers' hearing and reduce overall work safety. Therefore, this study aims to analyze the noise level in the work area in the production process of a company engaged in the metal casting industry and provide recommendations that can reduce the negative impact on the workforce. This measurement uses Decibel X with a time interval of five seconds, and then data processing is carried out to determine the LTm5 value. The measurement results show that the level of disturbance in some work areas exceeds the recommended threshold, increasing the risk of worker health problems. To reduce this negative impact, the study provides the provision of personal protective equipment (PPE), such as earplugs, as well as the implementation of occupational safety and health (OHS) socialization. This research makes an essential contribution to the management of nuisance risks in industrial environments, especially in improving worker safety and health through effective mitigation strategies.

Abstract

This study addresses the issue of controlling the inventory of raw materials for pen production at PT. XYZ uses Material Requirement Planning (MRP) to minimize excess inventory. The MRP calculates net requirements, planned receipts, planned order releases, and projected on-hand inventory based on estimated demand, product structure, lot size, lead time, and safety stock.  The results categorize 20 raw material components for ballpoint pen products into five levels, determining the optimal quantity and timing for ordering and receiving each component to meet production plans while avoiding excess stock or shortages. This study concludes that the MRP method can significantly optimize inventory management, reducing the risks of overstock and stockouts in the pen production process at PT. XYZ. Consistent application of the MRP method and regular evaluation of supplier capabilities are recommended to ensure efficient and effective raw material inventory planning and control.
