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.

Semarang City has experienced significant growth over the past five years (2020 – 2025). Rapid urban development has been positively correlated with increasing environmental burdens, particularly in solid waste generation. In Indonesia, the largest portion of municipal waste consists of food waste, followed by plastic waste. Among these, plastic waste is the most difficult to manage. It is estimated that around 70% of Indonesian households still burn their waste as a means of disposal. The burning of waste, especially plastics, releases toxic emissions such as dioxins, furans, and fine particulates, which pose serious health risks, particularly to the respiratory system. This practice not only worsens air quality but also threatens public health. This community service program focused on providing education about the thermal properties of waste and the negative impacts of plastic burning on both the environment and human health. The program aimed to improve public knowledge of the thermal characteristics of various types of waste and the hazards of plastic burning through accessible scientific outreach. The initiative is expected to raise awareness and understanding of environmentally friendly waste management alternatives such as waste separation, composting, and recycling. The activity was conducted in RW 01, Tugurejo Village, Tugu District, Semarang City.

Refill Drinking Water Depots (DAMIU) are businesses that provide ready-to-drink drinking water through raw water processing using simple and modern technology. The existence of DAMIU is very important in meeting the community's need for drinking water, but aspects of sanitation hygiene and water quality must remain a primary concern to avoid health risks. This study aims to describe the sanitation hygiene conditions and assess the microbiological quality of refill drinking water at DAMIU in the Indralaya Community Health Center working area in 2025. The study used a descriptive method with a laboratory approach to 27 refill drinking water depots. Data were collected through observations of location conditions, buildings, equipment, and handler hygiene, and laboratory examinations were conducted on raw water and processed water samples. The results showed that the majority of depots (92%) had met the requirements related to location and buildings, while all depots (100%) met the standards for processing equipment. However, drinking water handlers still did not comply with applicable hygiene standards (100%). Only 70% of depots had suitable raw water sources, with 55% using the Sukomoro source, 41% using drilled wells, and 4% using the Dewa Air Prabumulih source. Laboratory tests found that two depots (8%) had raw water that tested positive for Escherichia coli, but all treated water samples met established microbiological standards. Overall, this study concluded that the location, building, and equipment of the Drinking Water Supply Unit (DAMIU) in the Indralaya Community Health Center (Puskesmas) area were satisfactory, but handler hygiene remained a weakness that needed immediate improvement. Furthermore, the physical and chemical quality of the water still required attention, although the microbiological quality met standards.

This study was conducted to examine the effectiveness of Kevlar as a structural material in Medium Altitude Long Endurance (MALE) Unmanned Aerial Vehicles (UAVs), particularly those designed with winglet innovations. In UAV development, material selection plays a crucial role since it directly affects flight performance, fuel efficiency, and the overall durability of the aircraft structure. Kevlar is widely recognized as a lightweight yet highly durable material, making it an interesting candidate to replace more conventional options such as aluminum and carbon fiber composites. Two approaches were applied in this research: numerical simulations using aerodynamic software and experimental testing on a prototype wing and winglet reinforced with Kevlar. The analysis focused on comparing lift, drag, total aircraft weight, and fuel consumption between Kevlar-based structures and conventional materials. The results demonstrate that Kevlar significantly improves aerodynamic efficiency and extends flight endurance due to its lower weight. Moreover, Kevlar exhibits superior resistance to dynamic loads and impacts, which are critical during certain flight conditions. However, challenges remain in terms of higher production costs and more complex manufacturing processes compared to traditional materials. Despite these limitations, the findings provide valuable insights for developing more efficient and durable MALE UAVs, while also encouraging innovation in aerodynamic design through the application of winglet technology.

Colitis is an inflammatory characterized by thickening of the mucosal wall of the colon. The Colon In Loop examination is one of the diagnostic procedures for colitis, utilizing contrast media to assess the functional condition of the colon. At the Radiology Installation of RSUD (Regional General Hospital) Banyumas, the radiological procedure for Colon In Loop was performed on post-colostomy patients, thus differs from previous studies. This study aims to identify the examination procedure of Colon In Loop at RSUD Banyumas, the rationale for using Anteroposterior (AP) and Lateral projections, and the reason for not performing evacuation before the administration of negative contrast media. This qualitative descriptive study employed a case. The subjects included three radiographers, one radiology nurse, and one radiology specialist. The object of study was the Colon In Loop Post Colostomy examination procedure in colitis cases. Data were collected through observation, interviews, documentation. Data analysis involved data reduction and data presentation. confirmed with theory, and narrative presentation leading to conclusions. Result shows contrast media consisting of 250 grams of barium sulfate dissolved in 1000 ml of water (25% w/v). The examination is performed in stages followed by AP and Lateral projection imaging to evaluate contrast distribution in the colon. Negative contrast media administration is performed without prior evacuation to enhance patient comfort and reduce examination time. When administering negative contrast media, evacuation is not performed before air is introduced. This is done based on the patient's condition, to shorten the examination time, and due to considerations regarding the quality of barium sulfate; thus, evacuation could impair barium adherence to the colon mucosa. In conclusion, AP and lateral projections are considered adequate for establishing a diagnosis of colitis. The omission of evacuation is based on patient condition, time efficiency, and the suboptimal quality of barium. It is recommended to perform evacuation and increase barium concentration to improve adherence to the colon mucosal wall.

The management of household waste remains a major challenge in society, especially in densely populated rural and urban areas. The practice of open burning of waste is still often carried out because it is considered quick and practical, despite its negative impacts on health and the environment. The smoke from burning can trigger respiratory diseases, reduce air quality, and accelerate global warming. In light of this issue, the 2025 KKN-T 23 UMSIDA students initiated a community service program by introducing an innovation in the form of an environmentally friendly waste bin that can reduce the practice of waste burning. This waste bin is designed with a system for separating organic and inorganic waste and special ventilation that accelerates the natural decomposition process. Through a participatory approach, students involve the community in the planning, creation, and testing of the innovative trash bins. The results of the activities show an increase in community awareness in sorting waste, a decrease in the habit of burning waste, and an improvement in the quality of the surrounding environment. This program has also successfully fostered collaboration between students, village officials, and residents in creating a greener and healthier environment. This trash bin innovation is hoped to be a sustainable model that can be implemented in various areas as a simple yet effective solution for community-based waste management.

Concrete roof tiles are an important material in building construction, particularly for roofing work, due to their advantages in terms of strength, durability, and material availability. This study aims to analyze two main physical characteristics of concrete roof tiles, namely bending load and water absorption, using a literature review approach from various previous studies. Bending load refers to the material's ability to withstand bending forces, while water absorption describes the material's capacity to absorb and store water through its pores. These two properties significantly influence the quality and durability of roof tiles in facing external environmental conditions, especially wet-dry cycles and mechanical loads. The results of the literature review indicate that the use of waste as an aggregate substitute in concrete mixes can significantly improve the performance of concrete roof tiles. For example, research using broken roof tiles and ceramic waste as aggregate substitutes successfully increased flexural strength to a range of 12.5–15.0 MPa. Meanwhile, variations in water absorption were recorded in the range of 4%–8%, depending on the material composition and production method. This proves that the use of recycled materials not only supports sustainability but also improves the mechanical and physical properties of concrete roof tiles. Overall, this study underscores the importance of material innovation in concrete roof tile production, particularly utilizing waste as an alternative aggregate. However, further research is needed to explore the best combination of materials and production techniques for producing high-quality, efficient, and environmentally friendly concrete roof tiles.

Patients who are admitted to the Intensive Care Unit (ICU) often require mechanical ventilation due to respiratory failure. One of the common problems that arises in patients with mechanical ventilation is the buildup of sputum, which can interfere with the ventilation process as well as lower the tidal volume. To overcome this, a combination of clapping and suction interventions are used as a therapeutic method with the aim of helping to clear the airways and improve ventilation function. This study aims to determine the effect of the combination of clapping and suction on tidal volume in patients with respiratory failure using mechanical ventilation. The research design used a pre-experiment with a one-group pretest-posttest approach on 43 respondents in the ICU room. Interventions in the form of clapping and suction are given in a structured manner according to standard nursing procedures. The results showed that the majority of respondents were female (53.5%), with the most medical diagnosis being SNH (23.3%). Most of the respondents were in the late adult age category (32.6%) and used PCV ventilation mode (51.2%). Before the intervention, most respondents had a low tidal volume (72.1%), while after the intervention the majority had an increase to the normal category (90.7%). The Wilcoxon test showed a value of p = 0.001, which means that there is a significant effect of the combination of clapping and suction on the increase in tidal volume. Thus, it can be concluded that the combination of clapping and suction is an effective intervention in increasing tidal volume in patients with respiratory failure with mechanical ventilation at the ICU of RSI Sultan Agung Semarang.
