The work environment is closely related to the circumstances surrounding the activities of workers in doing their jobs. The office is a work environment where almost all the workers work mainly in a sitting position. Low back pain is one of the common occupational diseases of the workers. One of the risks of the increasing low back pain cases in workers is taking for granted the right work attitude, the location of the table and the size of the chair that is not ergonomic. RSIA Eria Bunda is one of the most visited RSIA by the public. The results of the initial observations at RSIA Eria Bunda found irregularities in work attitudes and the sitting positions of the employees and their work facilities were also not in accordance with the existing regulations. This is the reason the researcher conducted this research at RSIA Eria Bunda with the aim of knowing what factors can cause low back pain and what strategies can be used in handling complaints of low back pain in employees. The factors used in this study are individual and environmental factors and ergonomics. This research is conducted through quantitative approach with a survey method, cross-sectional data collection, low back pain questionnaire and RULA Worksheet to determine the employee's work attitude. Likewise, interviews and field observations are also conducted. Afterwards, determine the management strategy for complaints of low back pain with a SWOT Analysis. The results of the study are the following: First, there are complaints of low back pain in employees as 20 people (58,82%) and the most influencing factor is the work attitude (p = 0,022). Then, for the results of the RSIA SWOT Analysis, Eria Bunda is in a strong internal position and responds to existing opporto avoid threats.

In Indonesia, almost every year train accidents occur which result in casualties and considerable material losses. The factors that cause train accidents are human resources, facilities, infrastructure and environmental factors. The method used in this study is the measurement of the level of fatigue that occurs in machinists and assistant machinists using the fatigue index calculator and for measuring the quality of sleep whether good or not using the Pitsburgh sleep quality index questionnaire. Data collection is divided into two parts, namely the collection of working time data from machinists and assistant machinists to determine the level of fatigue and the collection of data from the distribution of questionnaires to determine sleep quality. Working time data is the schedule of machinists and assistant machinists every day which will then be calculated the level of fatigue using the fatigue index calculator. For the calculation of sleep quality, the Pitsburgh sleep quality questionnaire was distributed to 62 respondents. From the results of the calculation of the fatigue index calculator for machinists and assistant machinists every day, it is found that the fatigue index value varies for each day. This can also be seen from the results of the calculation of the standard deviation for 62 respondents which ranges between the value of 6 or 7. The results of the calculation of the sleep quality index showed that 84% of machinists and assistant machinists have a good sleep quality.

Car washes have become increasingly popular in some areas, but this growth has also had a negative impact on environmental quality, as untreated wash water is often discharged directly into car wash drainage systems without any prior treatment. This discharge of unfiltered wastewater can lead to high levels of COD (chemical oxygen demand) and surfactants in nearby water sources if carried out intensively. Much of the wastewater is often classified as waste. It is discharged by car wash operators into the drainage system and eventually into smaller waterways. In 2014, the Minister of the Environment highlighted the importance of managing cleaning waste due to its harmful effects on the environment and health. Based on the Pekanbaru Municipality's Regional Regulation No. 8 of 2003 on the payment of liquid waste treatment control permit, which stipulates that every industry must carry out waste treatment before discharging into the environment and each industry must also pay a fee, this study will allow the design of absorption wells, which will be used to treat liquid waste from car washes, so that the wastewater absorbed into the ground is no longer a contaminated liquid waste. By treating the waste by the method of infiltration pits, it is hoped that the environment and the health of the residents around the laundry will be well preserved.

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.

Sampah adalah sisa kegiatan sehari hari manusia atau proses alam yang berbentuk padat atau semi padat berupa zat organik atau anorganik bersifat dapat terurai atau tidak dapat terurai yang dianggap sudah tidak berguna lagi dan dibuang ke lingkungan. Pada prinsipnya, penyelenggaraan TPS 3R menggunakan konsep Reduce (mengurangi), Reuse (menggunakan kembali) dan Recycle (daur ulang) dimana upaya pengurangan sampah dilakukan di sumber pada skala komunal atau kawasan sehingga volume sampah yang diangkut ke TPA dapat berkurang secara signifikan. Proses pengolahan sampah yang berlangsung di TPS 3R meliputi proses pemilahan sampah yang secara umum dibagi menjadi sampah organik (dedaunan dan sisa makanan), sampah anorganik ekonomis (plastik, kertas, logam, kaca, dan lain sebagainya), sampah spesifik dan residu. Sampah organik diolah melalui proses biologis, sedangkan sampah anorganik dipilah secara mendetail agar dapat disalurkan kepada pelaku usaha daur ulang proses lanjutan. TPS 3R dapat berkolaborasi dengan bank sampah dalam rangka pengelolaan sampah anorganik ekonomis untuk mendorong pemilahan dapat dilakukan sejak dari sumber. Selain itu banyak cara lainnya yang berkembang saat ini agar dapat mendorong pelibatan aktif masyarakat. Pemilahan sampah sejak dari sumber diharapkan sudah terlaksana minimal 80% dari masyarakat yang terlayani TPS 3R agar mempermudah dan memaksimalkan pengolahan sampah di TPS 3R. Penelitian Desain TPS 3R ini dilakukan di Kelurahan Pematang Kapau, Kecamatan Kulim Kota Pekanbaru yang merupakan salah kelurahan di Kota Pekanbaru yang belum memiliki sarana TPS 3R. Desain TPS 3R ini diharapkan dapat menjadi solusi dalam mengatasi masalah sampah di Kelurahan Pematang Kapau.

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.

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.
