Perancangan Sistem Informasi Work Permit Berbasis Website pada Perusahaan Industri Pupuk
A fertilizer industry company, committed to upholding occupational health and safety (OHS) principles, faces high risks inherent to its chemical operations, such as lifting, jetty activities, chemical hazards, and fire hazards. Jobs with significant potential hazards require enhanced attention and monitoring to prevent accidents and undesirable losses. Accordingly, preventive and systematic control measures, including a work permit system, are necessary to ensure the safety of high-risk tasks. The conventional work permit system, however, is ineffective for the company due to its manual implementation, resulting in poor inspection reporting, insecure document storage, and inefficiency. Adopting a web-based work permit management information system can enhance the effectiveness and efficiency of the work permit process. This system, designed with a responsive web interface, provides easy and flexible accessibility via both computers and mobile devices, utilizing PHP and MySQL technologies. Compared to the traditional work permit, the proposed web-based approach streamlines the validation process, allowing the supervisor, area manager, and safety inspector to perform their steps simultaneously, thereby improving the overall efficiency of the work permit application.

Analisis Risiko Bahaya Pekerjaan Pengurasan Tangki Asam Fosfat di Industri Pupuk Menggunakan Metode Confined Space Risk Analysis (CSRA)
Confined spaces have limited or restricted access for entry and exit, and are not designed to be occupied by workers continuously. Since 2011 to 2018, it is known that the number of work accidents in confined spaces caused as many as 1,030 workers to die. Phosphoric acid is one of the crucial raw materials of the fertilizer industry that is stored in tanks and produces sludge. Phosphorus sludge contains high concentrations of zinc, mercury, cadmium, and lead that endanger the safety of workers when cleaning the tank. The problem to be solved in this research is the risk analysis of the hazards of phosphoric acid tank draining work using the Confined Space Risk Analysis (CSRA) method. CSRA can identify and assess hazard risks thoroughly by analyzing all risk factors of a job in a confined space. CSRA outlines a detailed risk analysis based on seven risk categories. The results of the CSRA analysis on the phosphoric acid tank draining work showed 22 potential hazards consisting of atmospheric, ergonomic, physical, chemical, mechanical, and falling. Risk assessment aims to determine the risk level of the work performed by evaluating the combination of consequences and likelihood of the related hazard risk, then providing control recommendations to reduce the risk level. After the control is applied, there is a significant change in the risk level of each potential hazard, namely from 21 potential hazards, there are 2 high potential hazards, 5 medium potential hazards, and 15 low potential hazards. The controls carried out are ensuring the gas content in the tank, installing worker information boards, and the use of mandatory PPE in accordance with company regulations.
Penerapan FMECA dalam Mengidentifikasi Kegagalan Komponen Kritis pada Rotary Kiln di Industri Semen
The manufacturing sector in Indonesia is experiencing rapid growth. One such company in this industry is a cement producer. Due to high market demand, the cement production process operates continuously, 24 hours a day. This makes the machinery and equipment used in the process susceptible to operational failures. The rotary kiln is a critical component in cement production, also running around the clock. The objective of this research was to identify failure modes and hazards associated with the rotary kiln's components. The study employed the Failure Mode Effect and Criticality Analysis (FMECA) method, an advanced form of Failure Mode and Effect Analysis (FMEA). FMECA enables the analysis of production processes, failure effects, failure causes, preventive actions, failure mode detection, and determination of the most critical failure modes. The FMEA analysis revealed 11 distinct failure modes, for which Risk Priority Number (RPN) values were calculated based on severity, occurrence, and detectability. These 11 failure modes were then subjected to criticality analysis using a criticality matrix. The criticality analysis results indicated that the cracked tire component failure mode is the top priority for corrective action.

Perancangan Ruangan Sandblasting dan Local Exhaust Ventilation untuk Pengendalian Debu Silika dari Proses Dry Abrasive Blasting
The sandblasting process produces silica dust which is dangerous for workers when inhaled and accumulates in the lungs, so that in the long term it can cause silicosis, which is one of the silicosis diseases. When the dust is not controlled in a closed room with a proper ventilation system and dust collection system, the dust can spread into the surrounding environment and endanger workers who do other work without proper personal protective equipment. In one of the contractor's fabrication workshops, work environmental dust measurements showed a value of 21.8 mg/m3 with the highest SiO2 concentration of 0.419 mg/m3 in a sandblasting area that did not meet standards. Based on mapping of respirable silica particulate matter, the affected area turns out to be quite large so engineering control is needed in the form of designing a sandblasting room and local exhaust ventilation. The room with dimensions of 8x10x7 meters was designed based on the needs of work objects that are frequently worked on by considering the ease of the process of getting work objects in and out. The inlet at the front and the air outlet at the bottom at the back of the room have dimensions of 8 m2 with a suction velocity of 3.7 m/s which will then be channeled through a duct with a diameter of 0.9 meters and a speed of 4500 fpm, to fabric filter as air cleaner with 100 filter bags 0.2 m in diameter and 2.6 m long. The pressure drop resulting from this design is 346.97 N/m2 so a fan power of 9892.115 watts or 13.27 HP is required in the form of a centrifugal fan. This design will produce air exchange 3 times per minute or 180 times per hour to reduce exposure to dust contaminants, maintain visibility during work, and keep dust contained and filtered before being released into the open air.

Penentuan Komponen Kritis Pada Kelistrikan dan Pelumasan Forklift Menggunakan Metode Failure Mode and Effect Analysis (FMEA) dan Diagram Pareto
Abstract— Forklift is a tool that enables an individual to lift and place heavy and large loads. Any malfunction in the forklift can hinder the production process or loading and unloading activities at a precast concrete company, leading to significant losses for the company if such issues occur. This tool operates continuously to transport materials and finished goods 24 hours a day, 6 days a week. Regular maintenance is required to maintain the performance of the forklift. To address these issues, researchers used the Failure Mode and Effect Analysis (FMEA) method to analyze the common causes of failure and their effects. This method is also used to determine preventive measures, from high to low priority, with the aim of reducing the level of damage or the likelihood of failure. Consequently, it is expected to reduce potential losses and hazards. Additionally, a Pareto diagram analysis was conducted to identify critical components, allowing the company to prioritize maintenance activities and improve reliability. The FMEA analysis shows that there are 35 components with 41 failure modes analyzed based on severity, occurrence, detection, and RPN (Risk Priority Number) values of each potential failure. The highest RPN value was found in the Lift and Tilt Cylinder component, with an RPN value of 270, identified with the failure mode of leakage/breakage. The Pareto diagram analysis prioritizes three critical components: Lift and Tilt Cylinder, Brake Pads, and Oil Filter. Therefore, these components should be the focus of the maintenance team and relevant parties in the company during forklift maintenance activities.
Pengaruh Beban Kerja Fisik, Lingkungan Kerja, Usia, Masa Kerja dan Kualitas Tidur terhadap Kelelahan Kerja pada Pekerjaan Packing, Langsir dan Input X-ray di Industri Makanan Gresik
Abstract— The Gresik food industry is one of the industries in Indonesia that produces snacks such as wafers, biscuits, and beverages. Thousands of workers strive to continuously improve the quality of the products. The high production demands that must meet daily targets result in work fatigue experienced by employees. This study aims to analyze the effects of physical workload, work environment (noise and work climate), and individual factors (age, length of service, and sleep quality) on employee work fatigue in the Gresik food industry. Objective measurement of work fatigue was conducted using a reaction timer. The method used in this study is ordinal logistic regression. The results of the ordinal logistic regression test show that there are four factors affecting work fatigue: physical workload (p-value = 0.11), noise (p-value = 0.004), age (p-value = 0.008), and sleep quality (p-value = 0.001). Work fatigue is more frequent among employees with excessive physical workload, employees in high noise areas, older employees, and employees with poor sleep quality. Recommendations that can be given include installing noise dampers on production machines that are the source of noise, conducting training or socialization on the importance of occupational health, job rotation, providing adequate rest, implementing appropriate shift work distribution, educating on the importance of sleep quality, socializing the implementation of stretching movements during work breaks, and providing personal protective equipment (PPE) such as ear plugs.

The initial process in making concrete involves carrying out iron fabrication work. This work does not pay attention to ergonomic factors such as standing for long periods of time and workers are required to work quickly and efficiently to achieve concrete production targets so that the work posture of bending, squatting, twisting body movements, bending the neck is carried out repeatedly, giving rise to complaints of musculoskeletal disorders. The results of the Musculoskeletal Disorders (GOTRAK) complaint survey felt by workers showed a 46% high risk of complaints. The parts of the body that have a high risk level are the hips with a percentage of 14%, the arms with a percentage of 11%, and the legs with a percentage of 10%. The description of the data shows that GOTRAK complaints among workers are quite high so it is necessary to carry out an analysis using a checklist of potential ergonomic hazards based on SNI 9011:2021. Iron bending work is the main focus of this research with work that has a risk of danger of 9. The results of this evaluation have a high risk considering the value exceeds a score of 7, so it is necessary to provide controls/recommendations. Recommendations that can be given are suggestions for improvements to the work station in the form of redesigning the size of the work table, the work table being redesigned at the height of the table to reduce the risk of ergonomic hazards and make workers more comfortable when working with a better working posture. The initial measurement for table height was 73, then an assessment was made to 100 by looking at anthropometric data for Indonesian men, diameter of standing elbow height and additional allowance for the soles of the shoes used by workers. After repairs were made to the work station, a reassessment was carried out and there was a decrease in score of 2, which was already in the safe category.

Perancangan Website Pengukuran Kelelahan Kerja Berdasarkan Reaction Timer
Fatigue is one of the issues that can decrease productivity and increase errors among workers. Currently, a commonly used tool to measure work fatigue is the Reaction Timer. However, this tool is still considered impractical because it requires assembly connections and relies on electrical power. Additionally, using this tool involves a manual process in taking workers' responses, recording, and calculating measurement results, causing the results to not be immediately available after the measurement is completed. To simplify the process of measuring work fatigue, a web-based work fatigue measurement tool was developed. This website was created using Visual Studio Code with PHP programming language and the Laravel framework. In the final stage of website testing, an average index value of 92% was obtained from the questionnaire. This indicates that the benefits of this website fall into the high category. Therefore, the website successfully meets user satisfaction and is very beneficial for them. The website testing results conclude that all features, ranging from the login process, form filling, audio and visual measurements, to measurement results and descriptions, as well as report generation in PDF format, function smoothly. Hence, this website is expected to significantly facilitate the measurement of work fatigue for its users.
