Noise is a physical hazard in the work environment that caan reduce hearing loss, especially in the rubber processing industry. The research aims to describe the noise level and control efforts in the production area of PT. Karet XYZ Palembang City in 2025. This study uses a descriptive design with a cross-sectional approach.  Data were collected through direct noise level measurements using sound level meters at wet and dry production areas by taking 8 measurements and questionnaires on 75 selected purposive sampling workers.  Data analysis was carried out univariately. It shows that most of the measurement points have a noise level above the threshold value of 85 dBA in accordance with the Regulation of the Minister of Health of the Republic of Indonesia Number 70 of 2016. The highest values were recorded in the Hummer Mill engine (89,76 dBA) and the Cooling Tunnel (89,70 dBA). All respondents were exposed to noise for ≥8 hours/day. Noise control has been carried out with administrative techniques and the use of personal protective equipment (PPE) but has not been fully effective from the complaints of 7 workers regarding suboptimal protection. The noise level at PT. Karet XYZ and duration of exposure exceeding threshold values that increase the risk to workers health. It is necessary to increase the effectiveness of noise control with a technical, administrative approach and monitoring the optimal use of personal protective equipment (PPE).

The purpose of this study was to analyze the relationship between noise levels and work stress among employees at Karunia Kasih Hospital. This study used a cross-sectional design with a population consisting of all employees in the Front Office, Polyclinic Nurses, and Specialist Doctors. The study sample consisted of 80 respondents selected using total sampling technique. Noise levels were measured using a Sound Level Meter, while work-related stress was assessed using a questionnaire. Data analysis was conducted using the chi-square test with a significance level of α = 0.05. The measurement results indicated that 80% of the work areas had noise levels exceeding the NAB 65 dBA threshold. The Outpatient Corridor area had the highest noise level (83 dBA). A total of 65% of workers experienced moderate to severe work-related stress. There was a significant relationship between noise levels and work-related stress (p-value = 0.001). Age (p-value = 0.024) and length of service (p-value = 0.037) also showed a significant relationship with work-related stress. There is a significant relationship between noise levels and work-related stress among workers at Karunia Kasih Hospital. Efforts to control noise levels and comprehensive stress management programs are needed to protect worker health.

Image processing has become a key technology in visual data analysis, making significant contributions across various fields such as healthcare, security, and the creative industry. This article provides a comprehensive review of the application of image processing technology in visual data analysis, focusing on the latest methods, tools, and practical applications. We discuss various image processing techniques, including segmentation, edge detection, and pattern recognition, as well as how these techniques are applied to process and analyze visual data. The study also includes performance evaluations of various commonly used image processing algorithms and software. Additionally, we explore the challenges faced in applying this technology, such as image resolution issues, noise, and high computational demands. By offering an extensive overview of the development and implementation of image processing technology, this article aims to be a valuable reference for researchers and practitioners working in the field of visual data analysis.

Construction work is one of the jobs that has various high risks for workers and people who are around it. These risks come from various sources, one of which is noise from various equipment and ongoing activities. One of the jobs that cause high noise in construction work is MEP (Mechanical Electrical Plumbing) work. Based on Permenaker Number 13 Year 2011, the Threshold Value (NAB) for noise that can be accepted by workers is 85 dBA for 8 hours a day. Based on the measurement of the construction of the flats, the MEP work in the form of Beam Separator Elevator Installation, Pipe Fabrication, Electrical Wiring Lighting Installation, as well as Welding and Grinding of Iron Pipe causes noise above the NAB. The highest noise comes from pipe fabrication in the form of iron pipe cutting activities using large grinding tools and bevel machines that produce noise of 107 dBA. From the Daily Noise Dose (DND) calculation, the noise generated from MEP work has a dangerous risk level for workers' hearing. Risk control efforts that can be done are preventive actions based on the K3 hierarchy in the form of administrative controls such as changing working hours or shifts and conducting safety talks before work is carried out. In addition, another preventive measure is the use of PPE such as ear plugs. Based on the calculation of the noise reduction level, the use of ear plugs has not reduced the noise level to reach the NAB, so it is recommended that workers in pipe fabrication work use ear muffs to reduce noise exposure.

The researcher chose the traditional game Bubuta'an to overcome noise outside the classroom due to school renovations which resulted in students' lack of focus on learning. The traditional game Bubuta'an is also a traditional game in South Kalimantan which in Indonesian is known as the game Si Buta-Si Buta. The aim of the research is to analyze the role of traditional babuta'an games in increasing students' learning motivation. The type of research used is Classroom Action Research with a qualitative approach. The research results show that the percentage of students' classical learning motivation obtained at the first meeting was 75% with the criterion "Mostly Skilled", at the second meeting it had increased to and had increased at the second meeting to 92% with the criterion " Almost All Skilled" and at the third meeting it had increased to 96% with the criteria "Almost All are Skilled" . This was because at the first meeting several students had not achieved the assessment indicators. So these conditions are below standards set by researchers for developing students' learning motivation. To overcome these obstacles, educators make improvements motivating, providing reinforcement, paying attention and reminding students to be more interested in participating in the learning process. The conclusions obtained by traditional game Babuta'an can be used as a means of developing students' learning motivation.
