Abstract

The work environment affects employee health, especially in offices where most employees sit for long periods. One common health issue is lower back pain, which can be caused by poor posture, non-ergonomic chairs and desks, and uncomfortable work settings. Initial observations showed that many employees had improper sitting postures and workstations that did not meet ergonomic standards.This research aimed to identify the factors that cause lower back pain and to find strategies for prevention and treatment. The study was conducted at a health facility using a quantitative method with a cross-sectional approach. A total of 34 back-office employees participated as respondents. Data were collected through a lower back pain questionnaire, the RULA (Rapid Upper Limb Assessment) worksheet to assess work posture, interviews, and field observations.The results showed that 20 employees (58.82%) experienced lower back pain. Factors that contributed to this condition included age, length of service, physical workload (EMK), and work posture. Among these, work posture was found to be the most significant factor (p = 0.022).To reduce lower back pain among employees, several strategies were suggested: forming an Occupational Health and Safety (OHS) evaluation team, improving the work environment and systems, and providing education about correct posture and back pain prevention. These steps aim to create a healthier work environment and reduce future complaints of back pain.

Abstract

Hospital is a facility in the health sector that provides services in both the medical and non-medical fields in order to improve the degree of public health. Good service in the medical field, especially radiology services, can improve health status and community satisfaction. This study aims to determine the relationship between outpatient satisfaction with radiology services at Puri Husada Tembilahan Hospital. This type of research is analytic to see the relationship between one variable and another with a cross sectional approach. The number of samples was 200 respondents determined by incidental sampling technique. The statistical test used is the Chi Square Test. The results showed that the p value was 0.000. So it can be concluded that there is a relationship between outpatient satisfaction with radiology services at Puri Husada Tembilahan Hospital. It is expected that all officers at the Radiology Installation of the Puri Husada Tembilahan General Regional Hospital to maintain the level of patient satisfaction with the quality of service at the Puri Husada Tembilahan General Regional Hospital.

Abstract

Flooding is an annual problem and has a major impact on the condition of society both economically, socially and environmentally. Flooding generally occurs due to overflowing rivers or the inability of rivers to accommodate excess river water due to high rainfall. The purpose of the study was to see how flood overflow in Parit Indah is simulated into a model so that it can be visualized and planned for appropriate and efficient control or mitigation efforts. The results of the analysis with the HEC-RAS model with input data of the maximum value of rainfall intensity in the last 10 years and the planned discharge of 2, 4, 6, 8 and 10 years, the results of the model exceeded the volume of the drainage channel and caused flood overflow around the beautiful ditch when the maximum rainfall intensity occurred

Abstract

Occupational Health and Safety (OHS) is an approach designed to prevent workplace accidents that may cause death, injury, or disability. If potential hazards in the workplace are not adequately identified and managed, they can lead to fatigue, musculoskeletal disorders, injuries, or serious accidents. Due to the high-risk nature of its production processes and the lack of ergonomic considerations, the kerupuk processing industry at UD Mamak Kito must pay greater attention to Health, Safety, and Environment (HSE). One method to support OHS implementation is the HAZOP (Hazard and Operability Study) method, which systematically identifies potential hazards in the workplace. The study identified ten high-risk conditions, primarily associated with the use of personal protective equipment (PPE), ergonomics, and exposure to high heat or hot oil. Six moderate-risk conditions were also found, including failure to use PPE and minor environmental hazards. Low-risk factors, including minor cuts and slippery surfaces, were additionally observed. Based on these findings, recommended improvements include enhancing workplace conditions and promoting safer work practices to reduce the risk of accidents and occupational health problems.

Abstract

Plastic Recycling Facilities (PRFs), although intended to reduce plastic pollution, can act as potential sources of microplastic release due to mechanical processing activities. This study aims to investigate the size and shape distribution of microplastics in polyethylene terephthalate (PET) recycling wastewater and to evaluate their removal behavior through coagulation–flocculation processes. Wastewater samples were collected from several treatment stages of the wastewater treatment system at a PET recycling facility. The results indicate that microplastics are predominantly fragment-shaped, with medium-sized particles representing the most abundant fraction. Coagulation–flocculation was shown to effectively remove microplastics, particularly fragment-shaped and medium-sized particles, compared to film and fiber forms. Removal efficiency was influenced by microplastic size and shape characteristics. These findings suggest that coagulation–flocculation has strong potential as an effective method for controlling microplastic release from PET recycling wastewater and provides a basis for developing more targeted wastewater treatment strategies.
