Occupational Health and Safety (OHS) is a crucial aspect in manufacturing industries due to the high risk of workplace accidents caused by heavy machinery, chemical substances, and intensive production activities. Companies usually provide Standard Operating Procedures (SOP) as safety guidelines; however, SOPs are often delivered in long textual formats that are less engaging, making workers reluctant to read or difficult to understand quickly. This study aims to design an infographic-based SOP media as an effective visual communication tool to improve workers’ understanding of safety procedures. The research applies a qualitative method with a design approach through workplace observation, interviews with HSE personnel, literature review, and design validation using questionnaires. The results produce infographic media in the form of posters and signage presenting PPE usage procedures, hazard warnings, and evacuation steps using safety color codes, icons, and readable typography. The conclusion indicates that infographic SOP media is more effective than text-based SOP because it improves readability, comprehension, and workers’ memory of safety procedures.

Occupational Safety and Health (K3) is an important aspect in protecting workers from potential accidents and health problems arising from work activities, including in the administrative sector, which is often considered low-risk. However, the Human Resources (HR) Department at PT Micro Madani Institute (MMI) Solo Branch still found several potential hazards and work risks that have not been optimally identified. This study aims to apply the Hazard and Operability Study (HAZOPS) and Job Safety Analysis (JSA) methods to identify and mitigate hazards and work accident risks in the HR Department's activities at PT Micro Madani Institute (MMI) Solo Branch. The research method is a qualitative study with a descriptive approach through observation and interviews. Risk analysis used the JSA and HAZOPS methods. The results of the study show that the application of the HAZOPS method in five sections of the HR Department successfully identified 53 potential hazards and risks, consisting of 12 extreme risks, 23 high risks, 15 moderate risks, and 3 low risks with the Employee Training and Development section as the section with the largest number of risks. Meanwhile, the application of the JSA method also identified 53 potential hazards and risks from 19 work activities. The dominant risks stem from non-ergonomic work postures, prolonged sitting, intensive computer use, and high workloads. This study concludes that the JSA and HAZOPS methods are effective in identifying potential occupational hazards and risks and can serve as the basis for control efforts to minimize workplace accidents and improve OHS implementation in the HR Department.

The retail industry is currently facing increasingly intense competition, requiring optimal supply chain efficiency. Warehouses play a strategic role in controlling inventory flows and supporting a company’s operational performance.

This research employs a quantitative method by distributing questionnaires to 40 respondents from the warehouse, purchasing, and procurement divisions using a saturated sampling technique. The research instrument uses a Likert scale. Data analysis was conducted using validity and reliability tests, classical assumption tests, multiple linear regression analysis, t-test, F-test, and coefficient of determination with the assistance of SPSS software. The results show that supplier compliance with SLA and delivery timeliness have a positive and significant effect, both partially and simultaneously, on warehouse operational performance. Therefore, improving supplier compliance with SLA and delivery timeliness can enhance optimal warehouse operational performance.

Occupational Health and Safety (OHS) is an important element in creating a safe, healthy, and sustainable work environment. PT. X as a logistics and port operations company has potential occupational hazards originating from physical, chemical, and biological factors that need to be managed optimally. This study aims to evaluate the implementation of OHS at PT. X based on the results of measurements of physical, chemical, and biological factors of the work environment and their compliance with the provisions of the Minister of Manpower Regulation No. 5 of 2018. This study uses a descriptive method with an evaluative approach to work environment monitoring data in 2025 in the generator and office areas. The parameters analyzed include noise, lighting, hot work climate (ISBB), inhalable and respirable dust exposure, and microbiological air quality in the form of total bacteria and fungi. The results show that most parameters meet the specified standards, with the exception of the generator area which exceeds the noise limit and the hot work climate which exceeds the Action Level (AL). The implementation of OHS at PT. X has been running quite well, indicated by most of the work environment parameters that meet the standards. However, strengthening risk controls, particularly regarding noise and hot working conditions in operational areas, is still necessary. This evaluation is expected to serve as a basis for continuous improvement in the implementation of Occupational Health and Safety (OHS) to protect workers from potential occupational hazards and support the productivity and sustainability of company operations.

This article explores inconsistencies in employee performance within small, project-oriented service sectors, where quality depends on daily tasks, punctuality, and adherence to procedures. Since skill development relies largely on informal workplace learning, differences in worker competencies often lead to rework, customer complaints, and safety issues. The study investigates how skills and competencies affect employee performance, illustrating how individual abilities translate into observable performance through the ability–motivation–opportunity (AMO) framework and experience-based learning. A qualitative case study at Rajasa Teknik included interviews and observations to examine project coordination, quality standards, and supervision practices. Results indicate that competencies and skills primarily influence ability, but sustained motivation- driven by realistic goals and fair feedback- along with ample opportunities such as smooth material flow, clear roles, and on-site decision support, enhance performance. The findings underline the importance of a cohesive work system (task division, quality control, communication), a consistent safety culture (K3), and straightforward, repetitive HR practices that facilitate tacit knowledge transfer into routines. Improvements suggested involve mapping core competencies, brief mentoring sessions, quality-focused standards, and evaluation systems to minimise service variation and promote sustainable performance in similar businesses. Overall, this research broadens the understanding of performance management in small enterprises and offers practical guidance for interventions.

Work activities in workshops often require static and repetitive body positions, such as bending over, lifting heavy loads, or reaching into narrow areas of vehicles. These habits can gradually cause muscle tension and lead to neck and lower back pain. Given the high risk, physiotherapy counseling on occupational safety and health (OSH) and ergonomics was conducted to provide practical understanding to B-Garage, Batu City workshop workers. The counseling was delivered interactively through material presentations, direct discussions, and demonstrations of stretching exercises that can be easily applied in daily activities. The results of the activity showed a very significant increase in knowledge; participants who initially did not understand the principles of ergonomics and musculoskeletal pain prevention were able to identify work risks and practice stretching exercises correctly after the education session. This change was clearly evident from the post-test results, which showed a significant overall improvement compared to the pre-test. These findings indicate that physical therapy education not only enhances knowledge but also promotes behavioral changes toward safer, more comfortable, and more productive work patterns.

This research is motivated by the declining level of work productivity of PT Rayung Pelangi Nusantara Purbalingga employees, which is suspected to be caused by the suboptimal implementation of occupational safety and health (K3), low organizational commitment, and less than optimal utilization of work experience. The main focus of this study is to analyze the influence of occupational safety and health (K3), organizational commitment, and work experience on employee work productivity partially. This study applies a quantitative approach through the application of multiple linear regression techniques with the help of SPSS version 25 software. The number of research samples consisted of 57 respondents selected using a purposive sampling method, while the data was obtained through a questionnaire instrument. The data analysis process involved validity tests, reliability tests, descriptive analysis, classical assumption tests, t tests, F tests, and coefficients of determination (R-Square). The research findings show that occupational safety and health (K3) has a positive and significant effect on work productivity, organizational commitment has a positive but not significant effect, and work experience has a negative and not significant effect. The coefficient of determination of 0.308 indicates that 30.8% of the variation in work productivity can be explained by these variables, while the remaining 69.2% is influenced by other factors not identified in this study. In conclusion, the increase in employee work productivity is more influenced by the implementation of good OHS, while organizational commitment and work experience have not shown a significant contribution. Therefore, companies are advised to strengthen the occupational safety and health (OHS) system and evaluate HR development strategies so that organizational commitment and work experience can have a greater impact on productivity.

Each workplace has a different potential risk of work accidents depending on the type of industry, technology used, and risk control efforts undertaken by the company. Work accidents are generally caused by two main factors: unsafe acts by humans and unsafe working conditions. In this context, occupational safety and health (K3) is an important aspect that must be implemented in every company to protect workers from hazards that can cause losses, both physical and work productivity. Law No. 13 of 2003 concerning Manpower mandates that every worker has the right to occupational safety protection. This study focuses on UD. Fuad Las Jaya, a company engaged in construction and welding services. This company has a fairly high potential for work accidents considering the type of work performed. Based on employee attendance data in 2025, there is a level of discipline that can be related to working conditions and perceived safety. The severity of accidents is classified into three categories: light, moderate, and severe, which indicates the importance of implementing an effective K3 system. It is hoped that consistent awareness and implementation of K3 will create a safe, healthy, and productive work environment, as well as reduce the number of work accidents in the construction sector.

Berkah Mandiri, located in Kediri Regency. The background of this study is based on the importance of implementing OHS in the workplace as an effort to minimize the risk of accidents, improve employee well-being, and support overall company productivity. In today’s increasingly competitive industrial world, attention to occupational safety and health is a key factor that not only protects workers but also enhances organizational efficiency and effectiveness. The research method employed was a quantitative approach with an associative research design. The population consisted of 56 employees, all of whom were taken as respondents through a saturated sampling technique. Data were collected using a questionnaire instrument constructed based on indicators of occupational safety, occupational health, OHSMS, and employee performance. The data were then analyzed using SPSS version 25.0 through validity and reliability tests, multiple regression analysis, and hypothesis testing both partially and simultaneously. The results of the analysis revealed that occupational safety has a significant effect on employee performance, indicating that the better the implementation of safety standards, the higher the performance achieved. Similarly, occupational health was found to have a positive and significant effect on employee performance, suggesting that healthy working conditions contribute to higher motivation and work effectiveness. Furthermore, the OHSMS also significantly influenced employee performance, reflecting that proper policies, procedures, and supervision in OHS management create a safe and productive work environment. Collectively, the three variables—occupational safety, occupational health, and OHSMS—were proven to have a significant simultaneous effect on employee performance at UD. Berkah Mandiri. Thus, this study emphasizes that occupational safety, occupational health, and OHSMS are crucial factors that must receive serious attention in order to improve employee performance and support sustainable business continuity.

This study aimed to evaluate the effectiveness of liquid organic fertilizer (POC) derived from kirinyuh (Chromolaena odorata) leaves on the growth and yield of potted corn plants. The research was carried out at the Agricultural Development Center (BPP) of Malimbong Balepe’, Tana Toraja District, South Sulawesi Province, located at an altitude of 815 meters above sea level. The experiment was designed using a simple randomized block design (RBD) consisting of four treatments: K0 = control (without treatment), K1 = 20% concentration of kirinyuh leaf POC (200 ml POC + 800 ml water), K2 = 40% concentration of kirinyuh leaf POC (400 ml POC + 600 ml water), and K3 = 60% concentration of kirinyuh leaf POC (600 ml POC + 400 ml water). Parameters observed included plant height at 5 and 7 weeks after planting (WAP), number of leaves at 7 WAP, ear length, ear diameter, and ear weight per plant. The results showed that kirinyuh leaf POC significantly affected the growth and productivity of potted corn plants. Application of POC at 60% concentration (K3) produced the best results, indicated by increased plant height, greater number of leaves, longer ear length, larger ear diameter, and higher ear weight compared to other treatments and control. This finding suggests that kirinyuh leaves, which are often considered as agricultural weeds, have potential as an alternative source of organic fertilizer that is environmentally friendly, low-cost, and effective in improving crop growth and yield. In conclusion, kirinyuh leaf-based liquid organic fertilizer, particularly at a concentration of 60%, demonstrated the highest effectiveness in supporting corn growth and productivity. These results provide practical insights for farmers to utilize locally available organic materials as an alternative to chemical fertilizers in sustainable agricultural practices.

This study aims to examine the influence of Occupational Health and Safety (OHS), workload, and compensation on employee productivity at PT Cahaya Karya Bersama. The background of this research lies in the importance of human resource management in enhancing company performance amid intense business competition.

This study employs a quantitative approach by distributing questionnaires to 40 respondents via Google Form, with data analyzed using SPSS 25. The results indicate that partially, OHS, workload, and compensation variables have a significant effect on employee productivity. Furthermore, these three variables also jointly contribute significantly to productivity enhancement. Therefore, the company must further optimize OHS implementation, ensure workload alignment with employee capacity, and improve its compensation system to create a productive and sustainable work environment.

This study aims to investigate the extent to which communication and occupational health and safety (OHS) influence employee performance at PT Sinergi Aitikom, South Jakarta, both partially and simultaneously. The research problem is based on the importance of effective communication and the implementation of OHS in creating a safe, productive work environment, and supporting the achievement of optimal performance. The research approach uses a quantitative method with an associative design, which allows for analysis of relationships between variables. The independent variables include communication (X1) and occupational health and safety (OHS) (X2), while the dependent variable is employee performance (Y). The study population is all 81 employees of PT Sinergi Aitikom, and because the number is relatively small, a saturated sampling technique is used so that the entire population becomes the research sample. Data analysis was conducted through validity and reliability tests, classical assumption tests, regression analysis, correlation coefficients, coefficients of determination (R²), and hypothesis testing using t-tests and F-tests. The results showed that the OHS variable significantly influences employee performance, as indicated by a calculated t-value of 10.698, which is greater than the t-table (1.990), with a significance value of 0.000 (<0.05). Furthermore, the F-test results reinforced this finding, with a calculated F-value of 304.857, which is greater than the F-table (3.11), and a significance value of 0.000 (<0.05). This proves that communication and OHS simultaneously have a strong influence on employee performance. The coefficient of determination (R²) of 0.887 indicates that 88.7% of the variation in employee performance can be explained by communication and OHS, while the remaining 11.3% is influenced by other factors outside this study. Thus, effective communication and sound OHS implementation have proven to be key factors in improving employee performance in the company.
