Abstract

One of the transportation supporting the economy in Indonesia is the ship. The government prioritizes the maritime sector in national development, which has a positive impact on the domestic shipping industry in the production of ships with various raw materials being developed. Fiberglass is a type of FRP (Fiber Reinforced Plastic) reinforcing fiber. In the manufacture of FRB (Fiber Reinforced Boat), fiberglass is an important part, its texture is light, and sharp, easily blown by the wind and can be inhaled into the breath which is not good for health. Indonesia is overgrown with coconut plants, parts of the coconut plant have many benefits, but coconut coir is less used, and is considered a waste that accumulates under coconut plants and is left to rot, therefore it is necessary to use coconut coir as an alternative to natural fiber from coconut coir. Synthetic fibers in the manufacture of composites. In this study, a study was conducted on the effect of composition on the tensile strength of coconut fiber reinforced composites, using a fiber delignification time of 45 minutes and the variation of fiber composition was 20%, 30% and 40% based on volume fraction. Coconut coir fiber is carried out by delignification process using NaOH solution with a concentration of 5% for 45 minutes. The composite with the highest tensile strength was 40% fiber composition, which was 60.96 ± 6.36 MPa. While the lowest tensile strength with a fiber composition of 20% is 31.88 ± 9.51 MPa.

Abstract

Abstract – PT. Aneka Adhilogam Karya is a national private company engaged in the sand-casting industry supplying its products to the Perusahaan Daerah Air Minum (PDAM) Indonesia. One of the products of piping supporting components manufactured is Clamp Saddle. Many of these products still have casting defects, such as gas porosity and shrinkage. Gating system is one of the most crucial factors to determine the quality of cast products. It is necessary to design a gating system for Clamp Saddle products. Then the casting simulation using ProCast 2018 needs to be done to get an optimal design and detect the presence of defect shrinkage or gas porosity. Furthermore, the sand casting process is carried out, and radiographic testing is carried out to detect defects in the inside of the Clamp Saddle product. The results of the study obtained agating system design with a pattern size of 400 mm x 335 mm then analyzed defects using ProCast 2018 on the variable total shrinkage porosity and air entrainment so that optimal results were obtained. Clamp Saddle product results from sand casting experiments were tested using radiography test(RT) to detect shrinkage or gas porosity and found some gas porosity but were still tolerable because of their small size of about 1 mm then they were few in number and were not gathered together

Abstract

Abstract – The red brick manufacturing industry is starting to be abandoned by many people and switch to using hebel bricks. Several things have caused red bricks to be abandoned, namely the price of red bricks is more expensive when compared to lightweight bricks for a size of 1 m2, besides that red bricks produced by conventional production processes have a red brick surface shape that is often uneven. Based on these conditions, we need an idea and innovation to create a machine to improve the production of red bricks in the form of a machine for smoothing and molding the clay of red brick for home-scale industries. The machine manufacturing process will use the Ulrich method from identifying machine requirements to selecting concepts and fabrication. Based on the results of the design using the Ulrich method, the design concept was chosen 1. Then planning, calculation and analysis will be carried out to determine the components to build the machine. The next stage is making of detailed drawings of the machine, followed by the fabrication and testing process. In testing clay smoothing and molding machine for red brick, the machine is capable of producing 120 red bricks per hour with a total cost of Rp. 12.217.500,-.

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,-
