Occupational health and safety (K3) is an effort to protect things that are dangerous so that everyone in the work environment is always safe and healthy. Creating a safe and healthy work environment can minimize the occurrence of accidents or accidents that can cause prolonged absences from work and significant costs for the company. Injured or sick workers can hinder productivity and disrupt work. The implementation of work safety basically aims to find weaknesses that exist and the possibility of accidents occurring in the work environment. This function consists of finding the cause and effect of an accident and investigating whether it is controllable or not. Labor productivity is a very important factor for companies, because the higher labor productivity, the more production or work results that can be provided in a certain time. To achieve maximum productivity, other things that are still related to labor productivity must also be considered. Among them are job opportunities, work motivation, work efficiency and effectiveness, work ability, as well as experience and knowledge that support the work process. Measurement of labor productivity is based on a system of physical income per person or hours worked per person based on working time or in days or years. By making these measurements, it is converted into work units, namely. into the amount of work that can be completed by employees working according to implementation standards in one hour. In short: The adoption of occupational health and safety in the workplace is an important factor in increasing the productivity and success of the entire enterprise. With the implementation of OSH it is possible to prevent work-related accidents and injuries, prevent employee absenteeism, which increases job satisfaction and creates competitive advantages that can lead to future employee success.  

Construction workers are often exposed to high risks of injury and illness due to potentially dangerous work environments. Therefore, the use of Personal Protective Equipment (PPE) is very important to protect them from various threats on construction sites. Literature research conducted in recent years has provided consistent evidence regarding the benefits and importance of using PPE in the construction industry. Various types of PPE, such as safety helmets, safety shoes, protective eyewear, respirators, and gloves, have been shown to be effective in reducing the risk of physical injury and exposure to hazardous materials. Literature studies also show that implementing strict policies related to the use of PPE can reduce the rate of work accidents and work-related illnesses. In addition, proper training and awareness of the importance of occupational safety have been proven to increase worker compliance with the use of PPE. Factors such as adequate availability of PPE, strict standards, a strong safety culture, supervision, and ongoing education are key elements in ensuring effective use of PPE and improving occupational safety in construction workplaces. Therefore, continued emphasis on the correct and consistent use of PPE is a must in efforts to maintain the safety and health of construction workers throughout the world.

Urban workers are increasingly vulnerable to heat stress due to rising global temperatures, especially in cities affected by the Urban Heat Island (UHI) effect. This heat stress poses significant risks to worker health and productivity, exacerbating health issues such as dehydration, heat exhaustion, and heat stroke, while also reducing work efficiency. The study aims to assess the effectiveness of green rooftop designs as a mitigation strategy for heat stress in urban workplace environments. Green rooftops are increasingly seen as a sustainable solution for urban heat management, offering benefits in temperature regulation, energy efficiency, and overall worker well-being. This study examines various heat stress mitigation strategies, including green roofs, industrial fans, and shading systems, focusing on their comparative effectiveness in reducing temperatures and improving worker comfort. The research involved environmental temperature measurements inside and outside urban workplaces, the use of wearable heat sensors to monitor workers’ heat stress levels, and building energy simulations to predict the impact of green rooftops on indoor climate control. Results indicate that green rooftops reduced workplace temperatures by an average of 3.8°C and decreased heat-stress-related complaints by 35%. In comparison to industrial fans and shading systems, green rooftops provided superior long-term relief, reducing heat stress and improving both worker productivity and environmental quality. The findings support the integration of green rooftops into urban workplace designs as a viable climate adaptation strategy. Future research should explore optimizing green rooftop designs for different climates and assessing their long-term benefits for worker health and urban resilience.
