This study proposes a computer vision-based system for automatically verifying the use of Personal Protective Equipment (PPE) in industrial environments. The system integrates the YOLOv8 object detection model, OpenCV for image processing, and a State Machine mechanism to manage the verification workflow. The verification process begins with employee identification through ID card scanning, followed by real-time detection of the head, safety helmet, and face mask using a camera, before generating a final PASS or FAIL decision. System evaluation was conducted using 250 testing scenarios to assess both model and system performance. The results show that the YOLOv8 model achieved an mAP@50 of 93.9%, while the overall verification system obtained 98.4% accuracy, 98.4% precision, 100% recall, and a 99.2% F1-score. The implementation of the State Machine contributed to a more stable and consistent verification process by ensuring that each inspection stage was executed in the correct sequence. These findings demonstrate that the proposed system can effectively support automated PPE compliance monitoring and has the potential to enhance occupational safety management in industrial workplaces. 

The governance of sand and gravel mining requires an integrated assessment of technical planning, occupational safety, environmental control, reclamation, and regulatory compliance. This study evaluated the governance of CV. Ria Bersaudara, a sand and gravel mining company located in Pasar Surulangun, Rawas Ulu District, Musi Rawas Utara Regency, using the Good Mining Practice framework. The study used a descriptive evaluative approach based on field observation, document review, indicative resource estimation, equipment productivity analysis, occupational safety and environmental risk assessment, and compliance mapping. The results show that the company has a basic legal foundation through an exploration mining permit covering 12.5 ha; however, several governance components require improvement. The indicative prospective area was approximately 2.50 ha, with an effective follow-up area of 1.80 ha and an estimated indicative resource of 21,600 m³ or 35,640 tons. Productivity analysis indicated that excavator capacity reached about 61 m³/hour, while one dump truck only transported about 10.3 m³/hour, creating a haulage bottleneck if the truck fleet is insufficient. Safety implementation was also not optimal, with personal protective equipment compliance estimated at only 55%. The study recommends validating permit documents, strengthening technical exploration data, improving drainage and sediment control, enforcing safety procedures, implementing progressive reclamation, and establishing daily operational records.

Chemical exposure during the dyeing process in the Textile industry has the potential to cause health problems, particularly allergic reactions mediated by Immunoglobulin E (IgE). Non-compliance with the use of Personal Protective Equipment (PPE) may increase the risk of chemical exposure through inhalation and skin contact, thereby triggering an allergic immune response characterized by elevated total IgE levels in the blood. This study aimed to determine the relationship between compliance with the use of Personal Protective Equipment (PPE) and total Immunoglobulin E (IgE) levels among Textile industry workers. This research was an analytic observational study with a cross-sectional design. The sample consisted of 15 Textile industry workers who met the inclusion and exclusion criteria, selected using purposive sampling technique. Data on PPE compliance were obtained through questionnaires and interviews, while total IgE levels were measured using the Electrochemiluminescence Immunoassay (ECLIA) method. The relationship analysis was conducted using Fisher’s Exact test. The results showed a significant relationship between PPE compliance and total IgE levels (p<0.05). It can be concluded that there is a significant association between compliance with the use of Personal Protective Equipment and total Immunoglobulin E (IgE) levels among Textile industry workers.

Healthcare-Associated Infections (HAIs) remain a major global challenge in healthcare services, contributing significantly to increased morbidity, mortality, and healthcare costs. Nurses’ compliance with the use of Personal Protective Equipment (PPE) is a critical component in infection prevention and control programs. Supervision by Infection Prevention and Control Nurses (IPCNs) is considered a key factor in improving compliance. This study aimed to analyze the relationship between IPCN supervision and nurses’ compliance with PPE usage in inpatient wards at Grha Permata Ibu Hospital, Depok, in 2025. This study employed a quantitative approach using a correlational analytic design with a cross-sectional method. The population consisted of all 56 nurses working in four inpatient wards, and total sampling was applied. Data were collected using a structured IPCN supervision questionnaire and direct observation checklists of PPE compliance. Data analysis included univariate and bivariate analysis using the Chi-square test. The results revealed that most respondents perceived IPCN supervision as moderate (58.9%), while the majority demonstrated compliance with PPE usage (62.5%). Bivariate analysis indicated a statistically significant relationship between IPCN supervision and PPE compliance (p = 0.001). Nurses receiving high-level IPCN supervision were 33.85 times more likely to comply with PPE usage compared to those receiving moderate supervision. In conclusion, IPCN supervision plays a crucial role in enhancing nurses’ compliance with PPE usage. Strengthening IPCN supervisory functions through structured monitoring, continuous education, and consistent evaluation is strongly recommended to improve patient and healthcare worker safety and to reduce the incidence of HAIs in hospital settings.

Industrial dust exposure is a hazardous work environment that can potentially cause respiratory problems in workers, particularly in industrial sectors with production activities that generate high levels of dust particles. This study aims to examine the relationship between industrial dust exposure and respiratory problems in workers through a systematic review. The method used was a qualitative descriptive literature study of scientific articles from 2021-2026 obtained through Google Scholar based on inclusion and exclusion criteria, then systematically analyzed. The results of the study indicate that most studies found a significant relationship between dust exposure and respiratory problems, especially in work environments with dust levels exceeding the threshold limit (TLV). Common symptoms include coughing, shortness of breath, phlegm production, and decreased lung function. In addition to dust levels, other factors such as duration of exposure, length of service, smoking habits, and the use of personal protective equipment (PPE) also play a role in increasing the risk. However, several studies showed insignificant results, which are suspected to be influenced by the use of proper PPE and an effective work environment control system. These findings confirm that dust exposure is a significant, multifactorial risk factor, necessitating comprehensive control efforts through a hierarchy of controls, environmental monitoring, and regular health checks to prevent long-term impacts on worker health.

Exposure to toxic materials in the workplace remains a major occupational health and safety issue, particularly in industrial sectors with high chemical use intensity. Various control efforts have been implemented through industrial hygiene and occupational safety (OHS) programs, but their effectiveness varies. This study aims to analyze strategies for controlling toxic material exposure through industrial hygiene and OHS programs based on literature review over the past five years. The method used was literature review of 10 national journals relevant  the topic of toxic material exposure in various industrial sectors. The analysis results indicate that toxic material exposure is still found in various sectors, with types of materials such as heavy metals, organic solvents, toxic gases, and industrial dust. The most commonly implemented control strategies are the use personal protective equipment (PPE), administrative controls, and some engineering controls such as ventilation. However, the effectiveness of these controls is less than optimal due low worker compliance, limited supervision, and the minimal implementation of higher-level controls such as elimination and substitution. Therefore, it is necessary to strengthen integrated industrial hygiene programs, improve worker compliance, and implement a more comprehensive hierarchy of controls to minimize the risk of toxic material exposure in the workplace.

The risk assessment suggests that most activities fall under the medium to high-risk categories, necessitating controls such as the use of Personal Protective Equipment (PPE), OHS training, and routine monitoring of working conditions. The implementation of the HIRADC method in this project is proven to enhance the culture of occupational health and safety and can serve as a reference for other construction projects in managing operational risks effectively.

Occupational health is an important aspect in maintaining worker productivity and safety, particularly in sectors with a high risk of chemical exposure such as gas stations (SPBU). Gas station workers are potentially exposed to hazardous chemical compounds such as benzene, toluene, and xylene which may affect the hematopoietic system and lead to decreased hemoglobin (Hb) levels. The use of Personal Protective Equipment (PPE) is one of the preventive measures to minimize exposure to these hazardous substances. This study aimed to determine the relationship between the use of Personal Protective Equipment (PPE) and hemoglobin levels among female workers exposed to fuel at gas stations in Kendari City. This study employed a quantitative research design with a descriptive analytic approach using a cross-sectional method. The population in this study consisted of all female fuel filling operators working at gas stations in Kendari City, totaling 30 workers, who were all included as research samples. Data on PPE usage were obtained through observation and questionnaires, while hemoglobin levels were measured using a Hematology Analyzer with venous blood samples collected in EDTA tubes. Data analysis was conducted using univariate and bivariate statistical tests to determine the relationship between PPE usage and hemoglobin levels. The results showed that out of 30 respondents, 21 (70%) had normal hemoglobin levels and 9 (30%) had abnormal hemoglobin levels. A total of 20 respondents (66.7%) used PPE according to the required standards, while 10 respondents (33.3%) did not meet the PPE requirements. Statistical analysis showed a p-value of 0.104 (p > 0.05), indicating that there was no significant relationship between PPE usage and hemoglobin levels among female gas station workers in Kendari City. The study concludes that the use of PPE does not have a significant relationship with hemoglobin levels among female gas station workers in Kendari City. However, the consistent use of PPE is still recommended as a preventive measure to protect workers from exposure to hazardous chemicals in the workplace.
