Keamanan dan kesehatan di tempat kerja adalah salah satu hal penting dalam membentuk suasana kerja yang aman, terutama bagi pekerja bongkar muat (TKBM) yang menghadapi risiko kecelakaan kerja yang cukup besar. Pemakaian Alat Pelindung Diri (APD) yang memenuhi standar merupakan salah satu langkah untuk mencegah terjadinya kecelakaan kerja di area pelabuhan. Namun, hasil pengamatan di Pelabuhan Tenau menunjukkan masih ada pekerja yang mengenakan APD tidak sesuai standar SNI dan tidak menggunakan APD secara lengkap saat bertugas. Studi ini bertujuan untuk mengevaluasi dampak pendidikan penggunaan APD terhadap pengetahuan keselamatan kerja pada pekerja bongkar muat (TKBM) di Pelabuhan Tenau. Penelitian ini mengaplikasikan metode kuantitatif dengan desain pre-eksperimental yang menggunakan pendekatan one group pre-test dan post-test. Sampel penelitian terdiri dari 28 responden dengan alat penelitian berupa kuesioner yang berisi 10 pertanyaan. Hasil penelitian menunjukkan bahwa sebelum mendapatkan edukasi, rata-rata responden berhasil menjawab dengan benar 6 pertanyaan (60%) dan memberikan jawaban salah pada 4 pertanyaan (40%). Setelah mendapatkan edukasi, hasil post-test menunjukkan peningkatan pengetahuan di mana sebagian besar responden dapat menjawab dengan benar sebanyak 9 pertanyaan (90%) dan jawaban salah berkurang menjadi 1 pertanyaan (10%). Berdasarkan hasil studi, dapat disimpulkan bahwa pelatihan penggunaan APD berdampak pada peningkatan pengetahuan keselamatan kerja bagi tenaga kerja bongkar muat (TKBM). Sehingga, diperlukan pengawasan dan pendidikan secara berkala mengenai pemakaian APD yang memenuhi standar SNI untuk meningkatkan keselamatan kerja di area pelabuhan.  

This study aims to improve subcontractor safety performance through strengthening governance systems, leading safety indicators, capability building, and performance monitoring at PT Putra Perkasa Abadi (PPA) Jobsite Borneo Indobara (BIB). The research was motivated by the increasing trend of subcontractor incidents during Quarter 1 to Quarter 3 of 2025, where seven incidents occurred and exceeded the company threshold. In addition, subcontractor performance evaluation scores remained below the target threshold of 70, while customer satisfaction scores in subcontractor management decreased from 8.45 to 7.58. The study applied a continuous improvement approach using Quality Control Circle (QCC), Pareto analysis, Nominal Group Technique (NGT), and root cause analysis with the Ishikawa method. Improvement initiatives were implemented through four strategic pillars: strengthening governance, reinforcing leading indicators, capability building, and integrated dashboard monitoring. The implementation results showed significant improvements in subcontractor safety management. The subcontractor incident frequency rate was reduced to zero incidents in Quarter 4 of 2025, subcontractor performance evaluation increased above the threshold to 70.81, and customer satisfaction scores improved to 8.55. The findings indicate that structured governance strengthening combined with real-time monitoring and subcontractor engagement can significantly improve mining safety performance and stakeholder trust.

Fractures are conditions where there is a separation or rupture in the continuity of the bone structure, caused by excessive pressure that the bone cannot withstand. According to the World Health Organization (WHO), the incidence of fractures is expected to increase with the growing number of vehicles. The productive age group is particularly vulnerable to injury due to accidents. A lack of knowledge about fractures and First Aid methods can exacerbate the situation. This study aims to determine the impact of fracture education and First Aid simulation methods on the knowledge of students at SMA N 1 Lhokseumawe. The research used a quantitative quasi-experimental design with a one-group pretest-posttest design, involving 91 students. The instrument used was a knowledge questionnaire. The results showed that before the education and simulation, 44 respondents (48.4%) had a poor knowledge category, while after the education and simulation, 84 respondents (93.4%) were in the good category. The Wilcoxon test resulted in a P-value of 0.000, indicating a significant impact. The conclusion of this study is that fracture education and First Aid simulation methods are effective in improving students' knowledge about fractures and First Aid.

This community service activity aims to improve the First Aid Awareness of students at SMAN 5 Tegal through health education and first aid simulation for accident management. The background of this program is based on the high potential for mild to moderate emergency incidents in the school environment, such as fainting, open wounds, nosebleeds, choking, and seizures, as well as the limited knowledge and practical skills of students in providing appropriate initial assistance. The implementation method consisted of three stages: preparation, delivery of health education using presentations and demonstrations, and hands-on simulation, followed by evaluation through knowledge assessment and skills observation. The participants were 54 students representing three grade levels. The expected outcomes of this activity include an improvement in students’ conceptual understanding and practical ability to perform first aid quickly, correctly, and safely before professional medical help arrives. In addition, this program is expected to foster emergency responsiveness, increase students’ confidence in handling accident situations at school, and contribute to the development of a safer and more prepared school environment. The outputs of this activity include increased knowledge and skill scores, documented implementation, and publication of a community service article in a SINTA-indexed journal.

This study was conducted to analyze the causes of occupational accidents and to identify potential hazards in the material cutting process at PT Kanaan Global Indonesia using the Job Safety Analysis (JSA) approach. The high number of occupational accidents, totaling 15 cases during the period of December 2024–May 2025, indicates the existence of gaps in occupational safety control in this area. Data were collected through direct observation, interviews with workers, and the collection of historical data from the Occupational Health and Safety (OHS) unit. Risk analysis was carried out using a risk matrix to determine likelihood and severity values, followed by JSA for each work stage. The results identified 25 potential hazards, consisting of 4 risks in the extreme category, 9 in the high category, 7 in the medium category, and 5 in the low category. High-risk hazards were predominantly found in roll cutting and cutting press machines, which are characterized by mechanical hazards. Control recommendations focus on the implementation of engineering controls such as the installation of guarding systems and safety light curtains, improvements in safe work procedures, and increased discipline in the use of personal protective equipment (PPE). These findings demonstrate that the JSA method provides a comprehensive overview of risk sources and serves as an effective basis for formulating occupational accident control strategies within the company.

This is related to the rights of traffic accident victims regulated in Article 240 of Law 22 of 2009 concerning Road Traffic and Transportation "traffic accident victims have the right to receive compensation from the party responsible and are entitled to insurance compensation from the insurance company". Article 1365 of the Civil Code, every person who commits an unlawful act is obliged to compensate for the losses arising from his or her mistake. In fact, many accidents occur due to damaged roads in Samarinda City, so this is one of the factors causing traffic accidents.The aim of this research is to answer two things. First, to find out and examine unlawful acts by the authorities in cases of traffic accidents due to damaged roads. Second, we want to know and examine the legal responsibilities of road operators. In this part of the research, we review and explore the relevant laws that regulate and are relevant to claims for compensation against road operators by victims of traffic accidents due to damaged roads.The results obtained from this research are as follows: 1) In this case, the occurrence of traffic accidents in terms of the last 5 years continues to show a significant increase, which means that the government has not maximally provided the community's rights, namely to have good roads. One of the causes of accidents is damaged roads, but to date no member of the public has filed a civil lawsuit against the government for compensation for the pain they suffered. 2) The government's regulations and efforts to provide protection for road users are sufficient, but they are not implemented optimally, in fact the public has never been given an appeal to demand their rights to receive good roads.  

Traffic accidents not only cause physical injuries but also significantly impact the psychological state of victims, such as trauma, anxiety, excessive fear, and other emotional disturbances. Post-accident psychological trauma can hinder daily activities and reduce the victim's quality of life if not properly treated. This study aims to examine the role of individual counseling in assisting the recovery process of psychological trauma in traffic accident victims. The study used a qualitative approach with a phenomenological design with three informants who were traffic accident victims and experienced psychological trauma. Data collection was conducted through in-depth interviews to explore the victims' subjective experiences during the recovery process. The data obtained were analyzed using thematic analysis techniques. The results of the study indicate that individual counseling plays a significant role in helping victims recognize and manage negative emotions, reduce anxiety and fear levels, and rebuild a sense of security, self-confidence, and adaptability. Thus, individual counseling is an effective intervention in supporting the ongoing psychological recovery of traffic accident victims.

This study employed a descriptive qualitative approach using a case study design to explore the psychological impacts of traffic accidents on victims. Data were collected through semi-structured interviews and direct observation, then analyzed using thematic analysis techniques. The findings indicate that the main trauma-related symptoms include intense negative thoughts or emotions, such as sudden fear, nausea, and mood changes characterized by increased sadness and irritability. Additionally, sleep disturbances were observed, including vivid nightmares, flashbacks when attempting to sleep, and physical reactions such as heart palpitations. Avoidance behaviors were also noted, such as avoiding the accident location, rarely leaving the house, and avoiding conversations related to the accident. Traffic accidents are sudden, unexpected events that can cause not only physical injuries but also profound psychological impacts, including fear, excessive anxiety, nightmares, and symptoms of post-traumatic stress disorder (PTSD). If left untreated, these psychological disorders may interfere with daily functioning and significantly reduce the quality of life of the victims, making early intervention crucial for recovery.

This study examines the application of restorative justice in traffic accidents during the investigation stage. The main focus of this research is to analyze the regulations and implementation process. The goal is to comprehensively describe how restorative justice policies are regulated by law and how they are practiced in the field, particularly by investigators. The research method used is a juridical- normative method with a qualitative approach. Data were obtained through literature review and in-depth interviews with relevant parties. The results indicate that restorative justice can be applied in resolving traffic accident cases, especially those resulting in minor losses or minor injuries. This regulation is contained in various regulations, such as Police Regulations and Circular Letters that serve as guidelines for investigators. The implementation process involves mediation between the perpetrator, the victim, and other relevant parties to reach a peaceful agreement. This agreement often includes compensation, an apology, or other mutually agreed-upon forms of reparation. The application of restorative justice aims to restore conditions to normal, restore social relationships, and avoid lengthy formal judicial processes. However, its implementation still faces challenges, such as unequal public legal awareness and the criteria for cases that can be resolved through restorative justice.

The rapid development and population growth in Bekasi Regency, Indonesia, have resulted in increasing traffic density and a corresponding rise in road traffic accidents (RTA), particularly along the critical 28 km Kalimalang Inspection Highway, locally known as "Jalur Tengkorak." This study aims to analyze the simultaneous and partial influence of Vehicle Factors (X1), Human Factors (X2), and Road Physical Condition Factors (X3) on RTA (Y). A quantitative descriptive approach utilizing Multiple Linear Regression (MLR) was employed, based on primary data collected through questionnaires from 100 motorcycle riders and secondary data from Polresta Bekasi (2022). The findings confirm that all three variables significantly and positively influence RTA, resulting in the model \hat{Y} = 2.218 + 0.302 X1 + 0.161 X2 + 0.289 X3 + \mu. The adjusted coefficient of determination (R^2) is 0.514, indicating that 51.4\% of RTA variation is explained by these factors. Crucially, the Road Physical Condition Factor (X3) emerged as the strongest predictor (t=4.429, \beta=0.385), surpassing the traditional dominance of human error. This key finding suggests that mitigation strategies must prioritize urgent infrastructure repair addressing potholes, road waves, and insufficient markings to significantly reduce accident frequency in this corridor.

Kidney trauma is a relatively common urological injury, often resulting from high-speed motor vehicle accidents, falls, or violent incidents. The kidneys are vulnerable to both blunt and penetrating trauma, with blunt mechanisms accounting for approximately 90% of all renal injuries. This paper reviews the anatomy of the kidney, mechanisms of injury, classification according to the American Association for the Surgery of Trauma (AAST), diagnostic evaluation, imaging modalities, and current management strategies. Most renal traumas are managed conservatively based on hemodynamic stability, while surgical exploration is indicated in severe or vascular injuries. Understanding the mechanism of injury and applying appropriate diagnostic evaluations are essential to determine the correct management approach and improve patient outcomes. Moreover, advancements in imaging techniques, such as CT scans, have significantly improved the accuracy of diagnosing renal injuries. Early intervention and appropriate monitoring are crucial in preventing complications such as hemorrhage or renal failure. This review aims to provide a comprehensive overview of renal trauma management to aid clinicians in improving patient care and optimizing recovery.

The Hazard and Operability (HAZOP) methodology is a qualitative risk analysis technique commonly used to detect potential work hazards. CV. Suryadi Sentosa, also known as Bapak Suryadi's Home Tempe Industry, is a home-based business that produces tempeh. Almost all of the production procedures are still carried out manually, and occupational accident analysis measures have not been implemented. The factory conditions indicate inadequate lighting and ventilation, as well as relatively slippery floors. It is also observed that the industry workers do not pay much attention to their posture, and they do not use personal protective equipment (PPE). This research was conducted directly at the CV. Suryadi Sentosa Tempe Factory, using interviews and observations of seven workers involved in the production process. The steps taken in this study are compiling the sequence of the production process. By using a Hazard and Operability (HAZOP) worksheet, identify potential risks, conduct risk control analysis, monitor and evaluate, implement improvements, and draw conclusions. The analysis found 9 stages of tempeh production at Mr. Suryadi's facility. Several improvements are needed, including involving several workers to handle soybean processing, creating ventilation to provide good and healthy air circulation for workers, adding lighting as a light source so that workers can perform their tasks comfortably, and using ergonomic chairs and work tables to prevent fatigue and increase factory productivity.

This research aims to analyze the risk factors of occupational accidents and identify effective prevention efforts within the context of Micro, Small, and Medium Enterprises (MSMEs), specifically at Inkside Sablon. This qualitative study, employing a case study approach, utilized in-depth interviews, participant observation, and documentary analysis for data collection. The findings indicate that occupational accident risk factors at Inkside Sablon are influenced by several aspects, including human factors such as lack of safety awareness and fatigue, environmental factors like inadequate ventilation and suboptimal lighting, and equipment factors such as non-ergonomic tools and insufficient maintenance. The prevention efforts implemented by Inkside Sablon are still partial and not well-structured, thus requiring the integration of more comprehensive safety programs, such as enhanced safety and health (OSH) training, provision of appropriate personal protective equipment (PPE), and improvements in management and supervision systems. It is expected that the implementation of these measures will increase worker awareness and reduce the number of occupational accidents, thereby creating a safer and more productive work environment

Occupational Health and Safety (OHS) is a systematic effort aimed at protecting workers from the risks of accidents and work-related diseases. The implementation of OHS integrated with risk management helps identify, evaluate, and control potential hazards effectively in the workplace. This study was conducted at PT. Sarana Sampit Mentaya Utama, Balikpapan Branch, a company engaged in asphalt production. The main objectives of this research were to identify potential hazards, determine appropriate control measures, and evaluate the role of the Job Safety Analysis (JSA) method in supporting OHS. The research method used is JSA, which involves identifying each work step, determining the likelihood and severity of risks, and calculating the risk rating to assess the level of risk. The results showed that there are three potential hazards with a medium-risk category, namely in the activities of raw material mixing, quality control, and asphalt distribution. Additionally, three potential hazards with a low-risk category were found in the processes of raw material weighing, raw material transfer, and pump line valve opening. Recommended control measures to reduce risks include the use of appropriate personal protective equipment (PPE) for each task, improving work facilities and infrastructure, and implementing proper load lifting procedures. The application of JSA has proven effective in raising the company's awareness of potential risks in the workplace. This has led to the implementation of better preventive measures, ultimately contributing to the creation of a safer, healthier, and more productive work environment. Therefore, the integration of OHS with risk management at PT. Sarana Sampit Mentaya Utama plays a significant role in safeguarding the safety and well-being of workers.

This study was conducted to analyze the effect of occupational safety and health (OHS) training, OHS compliance, and leadership style on the workplace accident rate among employees of PT. XYZ. Workplace accidents remain a significant problem in the industrial sector, thus this study seeks to provide a deeper understanding of the factors that can reduce this risk. The research method used was a quantitative survey approach, where primary data were obtained by distributing questionnaires to 40 respondents selected using a non-probability sampling technique with a purposive sampling method. The analysis techniques used in this study were descriptive analysis and multiple linear regression with the help of SPSS software version 25. The use of regression analysis allows researchers to determine the strength and direction of the relationship between independent and dependent variables. The results show that OHS compliance has a significant influence on the workplace accident rate. This confirms that compliance with occupational safety and health procedures can minimize the risk of accidents. Meanwhile, OHS training and leadership style did not show a significant influence on workplace accidents. This finding indicates that training programs and leadership style may not directly reduce workplace accidents unless they are consistently implemented and supported by strong compliance. Thus, OHS compliance is a key factor in creating a safe and productive work environment. This research provides a practical contribution for companies to focus safety management policies more on improving worker compliance with OHS regulations. Furthermore, the results of this study can serve as a reference for further research in different industrial contexts.

Tidaran 1 Hamlet, Candiretno Village, Magelang Regency, is a rural area with quite heavy traffic in several areas. One location of particular concern is the bends and T-junctions in RT 11, which are frequently used by both two-wheeled and four-wheeled vehicles. This area is known to be an accident-prone area due to blind spots that obstruct the view of drivers from both directions. Unfortunately, to date, there are no safety facilities such as traffic signs or convex mirrors to aid visibility. Seeing this problem, students participating in the Community Service Program (KKN) from Tidar University conducted an intervention based on community needs. One effort was the installation of convex mirrors to minimize the risk of accidents. This activity was carried out using an action research method (action research), which included field observation, risk analysis, solution design, implementation, and impact evaluation. Throughout the process, students actively involved the community, the RT head, and village officials to ensure the proposed solution was participatory and sustainable. Convex mirrors with a diameter of 80 cm and a 2.5-meter-high support pole were installed at strategic points on the bends. Following the installation, follow-up observations and interviews with local residents were conducted. The results showed a significant improvement in visibility for drivers, especially at night and in similar weather. Residents reported feeling safer, less hesitant when crossing, and more alert to oncoming traffic. This program not only improved safety but also raised public awareness of the importance of traffic management. Therefore, similar interventions can be replicated in other vulnerable areas, with collaborative support from the community, universities, and village government.
