Abstract

Three-dimensional (3D) printing technology, particularly the Fused Deposition Modeling (FDM) method, plays a crucial role in modern industrial design and ergonomics research. One of the primary challenges in this application is ensuring high precision, operational stability, and reducing mechanical wear to support the sustainability and efficiency of the printing process. This study introduces the development of a 3D printer based on FDM, utilizing the MGN12 linear slider as a replacement for conventional roller bearings. This innovation is designed to improve printing accuracy, optimize component durability, and maintain long-term operational quality. Empirical testing was conducted to compare the performance of the linear slider system and roller bearings in terms of dimensional accuracy, surface finish, printing speed, and mechanical durability. The results show that the linear slider system achieves dimensional accuracy of up to ±0.02 mm, better than the ±0.12 mm of the roller bearing system. The average surface roughness also decreased to 3.2 µm, compared to 5.6 µm in the roller bearing system. At high printing speeds (150 mm/s) with a layer height of 0.01 mm, the roller bearing system exhibited greater inconsistency, producing an average layer height of 0.04 mm, while the linear slider maintained high layer consistency. Additionally, the linear slider system reduced noise levels to 45 dB and significantly minimized mechanical wear, thereby reducing the need for regular maintenance. The findings of this study indicate that although the initial investment in linear slider technology is higher, it provides a significant improvement in 3D printing performance. This technology is highly relevant for industrial applications requiring high precision, process efficiency, and system reliability.

Abstract

Es Teh Klasik MSMEs are often short of key raw materials, such as cups and tea, which hampers production and leads to loss of potential sales. Inventory control is done traditionally so that stock outs often occur before the next procurement. This study analyzes the raw materials that are often short and the best control method using ABC Classification as well as the EOQ and POQ methods. Category A raw materials include cups, tea, sugar, plastic bags, and straws. The analysis shows that the EOQ method is more efficient for cup and tea, with costs of Rp 571,512 and Rp 529,943. While POQ is more efficient for plastic bags. EOQ also determines the ideal ordering frequency, for example for cup cups, 10 times per month with 5 packs per order, safety stock of 2 packs, and reorder point when 3 packs remain.

Abstract

Corrosion is the primary cause of premature infrastructure damage, affecting everything from homes and public spaces to industrial facilities, including the rapidly expanding palm oil industry in Aceh, particularly along its eastern and northern coasts. This rapid growth necessitates careful consideration of environmental impacts, including pollution, which can also degrade air quality. Pollutants increase the susceptibility of steel-reinforced structures to atmospheric corrosion. This research, therefore, investigates atmospheric corrosion of structural steel at several palm oil processing plants: PTPN 1 Tanjung Seumantoh in Aceh Tamiang, PT Ensem Sawita and PT Anugerah Fajar Rejeki (AFR) in East Aceh, and PTPN 1 Cot Girek in North Aceh.This study measures the atmospheric corrosion rate of structural steel typically used in industrial and nearby residential settings. Five steel types were tested: strip, angular, cylindrical, commercial plate, and low-carbon steel. Following the American Standard Testing and Material-G50 (ASTM G50), the mass loss method was used to calculate corrosion rates. After six months of exposure, all five steel types exhibited corrosion rates below 0.7 mils per year (mpy). This result showed that the relative corrosion resistance of structural steel is on outstanding category (<1mpy).

Abstract

Cybersecurity is a major challenge for energy infrastructure in remote areas that rely on distributed power grids. Limited resources and lower levels of monitoring compared to urban areas increase vulnerability to cyberattacks. This study analyzes the key risks faced by power transmission networks in remote areas, including restricted physical access, the use of outdated and vulnerable protocols, and insufficient network segmentation. To address these challenges, this research recommends a layered mitigation strategy, including data encryption, multi-factor authentication, network segmentation, and the adoption of blockchain technology. Additionally, training local staff and regularly updating software are crucial steps in enhancing network security. This study employs a literature review method, gathering and analyzing information from various sources such as books, journals, articles, and previous research findings. Data processing is conducted systematically to identify challenges and applicable solutions to improve the reliability of energy infrastructure in remote areas. The implementation of these recommended strategies is expected to reduce cybersecurity risks and enhance the security of power grids in such regions.

Abstract

Health problems related to an operator's posture while working can have a major impact on productivity and efficiency levels. To minimize the possibility of disturbances in posture and injury to operators, improvements are made to work methods, adjustments to machines or work aids, rearrangement of machine positions, and changes to work movements in accordance with suggestions from the RULA analysis. At ABC's Sumedang Tofu Factory, which consists of six work stations (washing, converting, pressing, grinding, molding, and packaging), ergonomic analysis indicated that incorrect working postures could cause discomfort and fatigue in the upper body of workers. After making improvements to the working posture, the final RULA value for the milling section was reduced from 7 to 2, and for the packing section from 5 to 3, indicating that the risk had decreased to an acceptable level. The REBA method also shows a decrease in scores in the milling section from 8 to 2, and in the packing section from 5 to 3, which indicates an improvement in working posture which is better and more acceptable

Abstract

PT. XYZ is a manufacturing company engaged in the production of notebooks and chemicals. This study aims to improve production efficiency in the oven division of PT. XYZ, especially on the SS-29 oven machine, by implementing the Lean Manufacturing and Systematic Layout Planning (SLP) methods. This study begins with an analysis of initial conditions that show various wastes, including excess material transfer, waiting time, and inefficient operator movements. The SLP approach is used to analyze the initial layout and design alternative new layouts by considering the results of the Activity Relationship Chart (ARC) and space requirements. Lean Manufacturing functions to identify and reduce activities that do not provide added value in the production process. The results of implementing the new layout show a reduction in material transfer distance by 41.12%, which has a direct impact on time and energy efficiency. In addition, production cycle time is significantly reduced, increasing operator productivity. This new layout also reduces waste in terms of waiting and transportation, while supporting a more responsive workflow. As a recommendation, PT. XYZ needs to immediately implement a new layout by considering implementation costs and impacts on ongoing operations. Continuous adjustment of the layout is also recommended to ensure the solution remains relevant, as well as to serve as a basis for further research in evaluating long-term impact and implementation in other divisions.

Abstract

The increasing awareness of environmental issues has influenced the use of eco-friendly materials, one of which is the use of natural fibers in biocomposites. Plant fibers are one of the sources of natural fibers that can be used as reinforcement in polymer matrix composites. Various studies have been conducted on many types of plants to explore sources of natural fibers. One natural fiber that has potential as a reinforcement in biocomposites is fiber from bark. In terms of physical and chemical properties, bark fibers can meet the criteria for reinforcement in polymer matrix composites. The tensile strength of single fibers from various types of bark ranges from 243.94 MPa to 1608 MPa. When compared to other natural fibers, such as ramie fiber with a tensile strength of 408 MPa and areca palm petiole fiber with 104.12 MPa, it can be concluded that bark fibers are equivalent to or even stronger than several other types of natural fibers. This review aims to provide background and information about the potential of bark fibers through several characterizations and tests, allowing for conclusions to be drawn regarding the feasibility of bark fibers as reinforcement in polymer matrix composites.

Abstract

Boilers are one of the supporting facilities that play an important role in hospitals. The steam produced by the boiler in the form of saturated steam is used for laundry purposes and to sterilize medical equipment where the temperature must reach/exceed 270 oF. Therefore, the saturated steam produced by the boiler is a source of sterilization used in hospitals today, including RSUP Dr. M. Djamil Padang. The research was carried out to determine the factors that cause leaks and determine appropriate maintenance actions. Based on the research results, it was found that oxidation corrosion and thermal fatigue occurred due to overheating so that the steam distribution pipe cracked/leaked. Maintenance activities: Arranging water access, checking and calibrating temperature and pressure sensors regularly, retubing if the thickness of the distribution pipe is only 71% of the initial design size or painting to protect the pipe in contact with water and air, or the pipe is wrapped in rockwool to prevent metal from coming into contact with water and air
