Abstract

Assembly lines that have poor efficiency result in various problems in the production process, one of which is the bottleneck problem. PT. Pindad (Persero) as a manufacturing company, has problems in the assembly line for special vehicles, where the efficiency of the assembly line has an unclear and uneven distribution of workloads, this results in poor production efficiency. This study aims to valuate the efficiency of PT. Pindad (Persero) and produce alternative improvements. An evaluation of the Komodo tactical vehicle product assembly line was conducted using line efficiency, balance delay, and smoothest index. It is known that the existing assembly line has a line efficiency of 13.25%, a balance delay of 86.75%, and a smoothest index of 875.31. Then the line balance is improved using heuristic line balancing methods. The methods used include the largest candidate rule, ranked positional weight, and regional approach. The results of this study are recommendations for special vehicle assembly lines using the line balancing ranked positional weight method with a line efficiency value of 94.1%, balance delay of 5.9%, and smoothest index of 8.86.

Abstract

The development of the metal industry cannot be separated from the utilization of supporting tools. The function of the supporting tools is to support processing time and improve product quality. In the process of making casting products, there is pattern making, namely the stages of making a replica of the product to be produced. Currently, the pattern-making process is still done manually and using conventional tools. It can take a lot of time and often the result of the pattern doesn't meet tolerance requirements. Constantly changing pattern geometry requires several sander machines to support the process, such as a disc sander to form a flat surface geometry, a spindle sander to form aradius surface geometry, and a belt sander to form the surface of objects that have a large surface area. Therefore, a combination sander machine is needed. This study uses the Ulrich method. The stages in the Ulrich method are identification of needs, determining the design concept based on the company's needs, determining the selected design, then doing the manufacturing process and testing the tool. Based on the design, design concept number 2 was chosen to actualize a product. In testing this machine is able to carry out the process of sanding pieces of wood for the bearing housing pump pattern for 38 minutes 44 seconds with a total budget of Rp. 5,454,000,-.

Abstract

The manufacturing industry is an industry where the machining process is done by hand or controlled with the help of machines that can run automatically and with manual supervision. Along with the development of industrial technology, the process of making the same product in large quantities and with precision becomes a requirement in the manufacturing industry. Jigs and fixtures appear as a problem solution for these conditions, but other problems arise from the use of jigs and fixtures. Tool changes and loading and unloading times cannot be utilized properly which can have a long-lasting adverse effect on manufacturing industry companies. There is a solution that helps to fix this problem, namely by updating the jig and fixture design using the Ulrich method, three jig designs and oval handle fixtures will be made using a plug and play system. Calculation of the cutting force received by the workpiece against the vise grip force to ensure the jig and fixture can hold the oval handle well. The results of the jig and fixture design research using the Ulrich method will be selected based on the highest value and safe cutting force calculations.

Abstract

Until now, the Ministry of Religion (Kemenag) has recorded that the number of Islamic boarding schools in Indonesia is 26,975 units as of April 2022. All of these Islamic boarding schools educate as many as 2.65 million students. With a number that is not small, it is not uncommon for an Islamic boarding school to experience problems in providing learning facilities such as tables and chairs. This makes most of the learning activities in the boarding house carried out by sitting on the floor. As a result, these habits have an adverse effect on the health of the students. These problems were reviewed using the Gotrak questionnaire and the RULA (Rapid Upper Limb Assessment) method. From the results of the preliminary study, it was known that many students complained of frequent aches or pain in the neck, back, hips and legs. And from the RULA method it shows a score of 5 which means moderate risk and further treatment is needed. From these problems, the idea was generated to make an ergonomic and portable floor chair. To solve this problem, product design and development will be carried out using the Ulrich method. The dimensions of this chair are 64 cm long, 42 cm wide,41 cm high when used on the cross-legged table, and 68 cm maximum height when sitting on a chair. In the test, the RULA score was 2, which means moderate risk and further treatment is needed with a total budget required of IDR 647.100,-

Abstract

This study investigates the application of renewable energy—specifically solar panels and wind turbines—in the electrical systems of fishing vessels. The research methodology includes literature review, power demand analysis, simulations, and experimental trials on a prototype fishing vessel. The findings demonstrate that integrating renewable energy systems can reduce fuel consumption by up to 30% and significantly improve operational efficiency. The adoption of a hybrid solar and wind energy system enables fishing vessels to remain at sea longer without complete reliance on fossil fuels. This study makes a notable contribution to the field of marine electrical systems and renewable energy by developing and validating a sustainable, energy-efficient onboard power system through a comprehensive empirical approach—ranging from technical design and simulation to field implementation. Key outcomes include a 30% reduction in fuel use and an increase in system efficiency to 85%, offering a practical solution for lowering operational costs among small-scale fishermen. The research also advances theoretical understanding of renewable energy integration in the maritime sector, which has predominantly focused on large commercial vessels. The incorporation of lithium-ion–based energy storage systems in small Indonesian fishing vessels presents a novel approach with significant development potential, particularly in addressing geographic and energy access challenges in remote coastal communities. These results provide a foundation for formulating government policies on subsidies and incentives to support the transition to green energy in the national fisheries sector.
