Abstract

Design and manufacture of automatic sheet metal bending machine tools in the press brake section with the aim of being able to streamline the operating time of bending machines in the Orange Teknik workshop. The main obstacle is that the bending machine is operated manually because it still uses an analog system. The main goal in creating this innovative tool is to assist the operation of a sheet metal bending machine so that it saves time and makes it easier to determine the results of the bending angle. In the process of designing and manufacturing automatic tools, it begins with an analysis of the problems in Orange Engineering, Literature Study, carrying out the design, manufacture and assembly of tools for bending machines, searching for bending data and analyzing data, creating equation formulas and ending with automatic data validation. The result shows that as the thickness of the plate used increases, the required punch force decreases, or the rotary encoder value becomes smaller to achieve the same angle as thinner plates. The effect of plate material variation in the bending process shows that the punch force applied in the press brake system is greater for black iron plates. Similarly, the rotary encoder value is higher to achieve the same bending angle compared to stainless steel plates.

Abstract

The era of industrialization requires humans to continuously strive to develop technology, one of which is the semi-automatic paint mixer machine. The purpose of this research is to determine the strength of the mixer machine frame and the motor mount frame of the paint mixer machine, through the analysis of von Mises stress, deformation, and safety factor. This research is a quantitative study using a descriptive method. The research design involves finite element method simulations using Ansys Workbench 2023 R1 software. Data collection techniques used are observation and documentation. Data analysis is performed using descriptive statistical techniques. The maximum von Mises stress analysis in areas 1, 2, and 3 resulted in values of 0.2975 MPa, 2.2619 MPa, and 3.4034 MPa, respectively. These results are still well below the yield strength of ASTM A36 material. This occurs around the area where the load is applied near the joint. The maximum deformation analysis in areas 1, 2, and 3 yielded results of 0.00038 mm, 0.00415 mm, and 0.0274 mm, respectively. This occurs around the area near the front edge where the load is applied away from the joint. The safety factor analysis in areas 1, 2, and 3 resulted in a value of 15. This exceeds the required safety factor, indicating that the frame is safe to withstand the applied loads.

Abstract

Metal penetration defects can slow down the fettling duration. This study examines the effect of zircon filler percentage, viscosity level, coating amount on the mold, and agitation on fettling duration in the metal casting process of the Komatsu PC2000 Excavator Track Shoe. The research method used was a True Experimental Post-test Only Control Design. The research samples were randomly taken from molds that were in production, and the data analysis technique used was descriptive statistics. Based on the results, changing the coating from 60% zircon to 80% zircon can reduce the fettling duration by about 10 minutes. If the viscosity of the 80% zircon coating is reduced to 55-60 Baume, the fettling duration can be shortened by up to 23 minutes. However, this would increase production costs by Rp. 38,532,900 per month. To address this, the coating mass on the mold was reduced by one-third, shortening the fettling duration by 20 minutes, with an additional cost of only Rp. 3,333,000 per month. Moreover, applying agitation to the 60% zircon coating can reduce fettling duration by up to 29 minutes without any additional costs.

Abstract

Bananas are one of the main plantation commodities in Pagerharjo Village, Samigaluh. The local women's farmer group (KWT) processes bananas into chips, but the manual production process creates obstacles because the slices are not uniform. This study aimed to determine the working mechanism of a semi-automatic banana chips slicing machine, identify the most effective test result, and compare production capacity between machine-assisted slicing and manual slicing. The research used a research and development (R&D) method implemented through observation, interviews, problem formulation, product needs analysis, machine performance testing, data collection, and data analysis. Experimental testing was conducted in three blade-gap variations to obtain the most effective slicing result. The machine used a 1/4 hp electric motor with a nominal speed of 1400 rpm. The most effective result was obtained at a 4 mm blade gap, which produced an average slice thickness of 3 mm, 747 g of slices meeting the standard shape from 1 kg of bananas, and a slicing capacity of 27 kg/h.

Abstract

This study aims to increase production effectiveness in the fabrication process for the PT Pou Yuen Indonesia workshop construction by applying Lean Manufacturing and Manufacturing Cycle Effectiveness (MCE). The research used a quantitative descriptive method by taking representative samples from the overall production process in the cutting, setting, and submerged arc welding (SAW) lines. Data were collected through interviews, observation, documentation, and measurements of process time and transfer distance. The results show that the most effective cutting method is the method used by MSS, which applies a double-nozzle cutting process. In the setting process, the most effective methods are those used by MKR and MSS because they require fewer workers and have shorter process times than SST. In the welding process, the most effective method is the method used by MKR because flux is supplied during the welding process. Several types of waste were identified, including waiting time, transportation waste, inventory waste, motion waste, and processing waste. Applying the recommended process methods can reduce the total production process time by 9,011.99 seconds for one WF beam and reduce transfer distance by 2,070 m.

Abstract

This study investigated the effect of melt temperature and injection pressure on filling time in the injection molding process for shop hanger products. The research used an experimental simulation method with Autodesk Moldflow Adviser 2023. The melt temperature was varied at 180, 190, 200, 210, and 220 °C, while injection pressure was varied at 20, 30, 40, and 50 MPa. Runner diameters of 2, 4, and 6 mm were also evaluated to determine the most suitable flow channel for the mold design. The results show that a 4 mm runner produced the shortest filling time among the runner variations. Increasing temperature and pressure tended to reduce filling time within the tested parameter range. The shortest filling time was obtained at a melt temperature of 220 °C and an injection pressure of 40 MPa with a 4 mm runner. Several defects, including short shot, warpage, weld lines, sink marks, and air traps, were detected during the simulation, but the defects were not significant under the optimal parameters. The mold was designed with a 330 × 350 mm mold base and a required clamping force of 470 kN. The selected injection machine available at CV. Mulus Teknik, a 90-ton UN90SKII machine with a clamping force of 900 kN, was suitable for production.
