Abstract

Activities at sorting stations and boilers are high risk activities. Incorrect body posture, done repeatedly and relying on manual human power causes musculoskeletal disorders (MSDS). This research aims to analyze MSDs disturbances in body parts of workers at sorting  stations and boilers using the Ovako work posture analysis system (OWAS) method. OWAS can identify four body parts in a worker's posture, namely the back, upper arms, legs and weight category. Based on the results of the OWAS assessment, a score of  4144 was obtained at the sorting station, and 4141 at the boiler station. Both scores are in category 4, which means improvements need to be made as soon as possible. The injury risk index reached a value of 400 for both stations, indicating a very high level of danger.

Abstract

PT. Mitra Bumi is a company operating in the palm oil sector that produces CPO and so far wants to know the level of productivity. OMAX is a partial productivity measurement system developed to monitor productivity in each part of the company with productivity criteria that are appropriate to the existence of that part (objective). Productivity is an important factor to support the survival of a company by analyzing and evaluating the output obtained based on its level of performance during a certain period. To find out the current level of productivity in the production department, it is necessary to measure productivity, because the results of this productivity measurement can be used as a consideration for implementing efforts that can be made to increase the company's productivity. Productivity measurements at PT Mitra Bumi are carried out using the method, objective matrix analysis (OMAX). The criteria used in this research are raw material productivity, effective working hours productivity, machine working hours and production effectiveness. The highest productivity index value was in July with a total value of 112.00%, while the lowest value was in June with a value of -91.33%. The cause and effect diagram is used to determine the causes of the decline in productivity in the CPO production section. As a result, production productivity at PT Mitra Bumi was influenced by factors that caused productivity to decrease, namely damage to the tippler machine, unsuitable raw materials, and less skilled operators

Abstract

The company converted rubber plantations into palm oil plantations to enhance operational efficiency. Palm oil is considered more profitable as its maintenance is simpler, production costs are lower, and harvesting can be done year-round without being affected by the seasons, unlike rubber, whose production decreases significantly during the rainy season. This is expected to increase the company's overall productivity and profitability. This research aims to determine the productivity of palm oil and the soil nutrients in the rubber-converted land at Kebun Tamora, PT. Perkebunan Nusantara V, Kampar Regency, Riau. The research was conducted from September 1 to November 1, 2023, using a quantitative and qualitative descriptive analysis method, utilizing secondary data. The results indicate that plantation productivity varies but has shown continuous increases year after year. For example, for the 2014 planting year, production increased from 16.150 tons/ha in 2018 to 33.127 tons/ha in 2022, while for the 2015 planting year, productivity reached 31.867 tons/ha in 2022.

Abstract

Three-dimensional printing (3D printing) technology has developed rapidly and offers innovative solutions in the manufacturing industry, especially for replacing damaged machine components. This research aims to analyze the perception and effectiveness of this technology as an alternative through empirical data from 300 respondents. The test results show that perceptions of 3D printing's ability to replace traditional components, the quality of the print results, and environmental benefits are significantly influenced by the respondent's level of experience (p-value < 0.05). However, aspects of cost efficiency and ease of application of technology show uniformity of perception across all groups of respondents, indicating the potential for broad application of technology. The normality and ANOVA tests performed confirmed the validity of the data, supporting the use of parametric statistical analysis. These findings underscore the ability of 3D printing to reduce costs and production time, while highlighting key challenges related to material strength and initial investment. This research recommends the development of materials, hardware, and ongoing education to increase the acceptance and effectiveness of the application of this technology in the manufacturing industry.

In an increasingly competitive industrial era, reducing waste and increasing operational efficiency has become a primary focus for many organizations. The 5S method, namely Seiri (Sort), Seiton (Arrange), Seiso (Clean), Seiketsu (Standardization), and Shitsuke (Discipline), which originated in Japan and was introduced into the Toyota production system in the 1950s, offers a systematic approach to creating an orderly and clean work environment. This research aims to explore the implementation of 5S at PT XY, with a focus on its impact on operational efficiency and reducing waste in the cement production process. The methodology used in this research includes literature studies and case studies, where data is collected through interviews, direct observation and documentation analysis. The research results show that implementing 5S can increase productivity, create a more organized work environment, and increase employee satisfaction. However, there are several challenges in implementation, especially in the aspects of standardization and discipline among employees. This research also identified problems faced in the project warehouse, such as a lack of personnel, insufficient area, and misunderstandings in shipping goods. Recommendations for improvement include employee training, establishing more comprehensive procedures, and grouping items by type to increase efficiency. Thus, it is hoped that the application of the 5S method at PT XY can create a better work culture and support the sustainability of operational efficiency practices in the future. These findings provide valuable insights for other industries looking to implement 5S to improve their performance and competitiveness.
