The implementation of healthy and safe school standards is a strategic effort to create a learning environment that supports the health and safety of elementary school students. This study aims to evaluate the implementation of healthy and safe school standards at SDN 6 Kendari, which is characterized by its proximity to a market and a main road. The study employed a qualitative approach using a case study design, involving field observations, the completion of a healthy and safe school indicator questionnaire, and interviews with educators. The results indicate that SDN 6 Kendari has met most of the healthy school indicators, evidenced by well-maintained buildings, adequate ventilation and lighting, proper sanitation and waste management, and students’ consistent practice of clean and healthy living behaviors. Regarding the safe school aspect, the school’s social environment is relatively conducive and free from risky behaviors, supported by the availability of a monitoring system and collaboration with relevant parties. However, several areas still require improvement, such as the equitable distribution of handwashing facilities, more strategic placement of portable fire extinguishers, and strengthening traffic risk mitigation measures due to the school’s location. Overall, the implementation of healthy and safe school standards at SDN 6 Kendari has been proceeding well, but requires continuous improvement to achieve optimal compliance with the standards.

Human activities, from household to industrial operations, generate liquid waste that poses a threat to the environment. Before discharge, liquid waste should be treated to ensure it is safe for release into the environment. This study aims to evaluate the effectiveness of a hybrid ozonation-adsorption method with varying contact times. This study collected leachate samples from the Rajabasa Landfill and used fly ash from the Tarahan Coal-Fired Power Plant as the adsorbent. First, the study used contact times of 20, 40, 60, and 80 minutes for ozonation. Subsequently, the 80-minute sample proceeded to the adsorption stage and was ultimately tested against six parameters. The measured parameters included COD, TSS, TDS, turbidity, UV254, and DO. The results showed that the 80-minute ozonation process significantly reduced TSS, TDS, and DO levels. However, the ozonation process still left intermediate compounds, which were subsequently removed by adsorption. Ultimately, the combination of the two processes yields good results, particularly for COD and UV254. This aligns with the theory that ozonation breaks down complex compounds while the adsorbent absorbs residual pollutants. This hybrid process achieves a 45.47% reduction in COD and an 87.83% reduction in UV254.

Lifting activities are an essential part of manual material handling across various industrial sectors and constitute a primary source of ergonomic risk exposure when performed with inappropriate work postures. The use of hands-off tools such as push-pull sticks is often implemented to maintain a safe distance between workers and loads and to reduce exposure to line-of-fire hazards. However, the implementation of work aids does not automatically ensure neutral work postures, as push-pull techniques, reach distances, and environmental conditions can still lead to awkward postures. This study aims to evaluate the work posture risk in lifting activities using a fiber-composite push-pull stick based on the Rapid Entire Body Assessment (REBA) method. The research was conducted as an observational analytic field study involving nine workers in tubular pushing and pulling activities. Work postures were documented through direct observation and visual recordings, then assessed using REBA to obtain risk scores, risk categories, and required corrective actions. The results indicate that work postures fall into the medium to high-risk categories, with trunk and shoulder components being the dominant contributors. These findings confirm the need for improvements in work methods, ergonomic training, and strengthening of lifting SOPs to optimize the safety and ergonomic benefits of work aids.

This study aims to analyze the effectiveness of waste management in preventing fires at the Alak Landfill (TPA) in Kupang City using a qualitative case study approach. Data was collected through interviews, observations, and documentation involving officials from the Environmental and Sanitation Office, landfill workers, waste pickers, and surrounding communities. The findings indicate that the effectiveness of waste management remains low. In terms of input, financial resources, infrastructure, and human resources are insufficient to support optimal operations. During the process stage, waste collection and transportation are hindered by low public compliance, limited vehicles, and minimal waste segregation. Final waste processing still relies on the open dumping method, which increases waste accumulation, methane generation, and fire risks. In terms of output, various mitigation efforts have not successfully reduced the recurring fire incidents due to limited facilities, inadequate compaction, and the absence of gas monitoring systems. The results highlight the need for increased budget allocation, improved facilities, enhanced human resource capacity, and the implementation of safer and more sustainable waste management methods to reduce fire risks at the Alak Landfill.

The traditional homes of indigenous communities in Indonesia are highly vulnerable to natural disasters, particularly earthquakes, due to Indonesia's location in the Pacific Ring of Fire, which experiences high seismic activity. This situation demands the strengthening of traditional buildings to withstand potential earthquakes. Stilt houses, as a form of traditional architecture, possess characteristics that actually support earthquake resilience, such as flexible structures, the use of lightweight materials, and the application of local wisdom passed down through generations. With the development of modern construction techniques, stilt houses have the potential to become safer and more adaptable dwellings to earthquake shocks. However, indigenous communities, particularly those living in earthquake-prone areas and with lower levels of education, often face limited knowledge and skills related to the basic principles of earthquake-resistant construction. This lack of understanding results in traditional house construction without considering structural safety aspects, ultimately increasing the risk of serious damage and even collapse during an earthquake. These impacts not only threaten life but also cause significant material losses. This community service activity aims to improve the preparedness and resilience of the Sentani Indigenous community by developing earthquake-resistant stilt house models, increasing knowledge and skills in earthquake-safe house construction and maintenance, and encouraging the use of innovative technology and materials. The expected outcomes are the creation of model houses that can serve as examples and the dissemination of information on earthquake-resistant construction technology.
