Abstract

In the machining process, the speed grip of the CNC Router spindle on the surface area of the activity entity is very closely monitored and the physical quality of the cutting surface is also on the amount of cutting speed, thickness of the tape and the strength of the film. The aim of the study is to understand the speed grip of the CNC Router on the surface mill system on the surface surface of the activity entity. using spindle speeds of 1000 rpm, 1200 rpm and 1400 rpm. The equipment and materials in this study are aluminum and measuring equipment. Based on the results of the visual study, it was found that the largest and most aggressive flat body was seen at a spindle speed of 1000 rpm, and a stable flat body was seen at a spindle speed of 1200 rpm, then the smallest or strongest flat body was seen at a speed of 1400 rpm while the data from studies using Roughness Tests, it shows that the average Ra point at a spindle speed of 1000 rpm is 0.33 um, at a spindle speed of 1200 the Ra point is 0.30 µm, and at a spindle speed of 1400 rpm the Ra is 0.29 µm. From the results of the study, it was found that the smaller and higher the spindle rotation, the grip on the physical surface on the face mill of the experimental entity and the higher the speed of the spindle, the smoother the surface, and vice versa, the smaller the spindle rotation, the more aggressive the surface. Keywords: Spindle Speed and Surface Roughness.

Abstract

Abstract: Growing industry in the world right now, then all the company continues to improve the quality of its products in the order to compete with other companies. One way the company is done by providing improved quality in the production process that aims to increase a better product without raising the cost of production. Improvement of product quality is done by creating a work tool that is easy to use and can reduce the number of errors on a production process to produce quality products that can compete in the global market.

Abstract

Material replacement in a product is a fatal thing for a company, because it will have a big impact on production operations, including the regulation of machine parameters, product quality, and production costs themselves. The difference in the specifications of the two materials will have a big impact on the parameter setting of the injection molding machine including the quality of the products it produces. Therefore, finished parts from new materials must be tested first to ensure that parts with new materials have no problems during the production process or customers later.

Abstract

Implementation of Overall Equipment Effectiveness (OEE) in Enhancing Forklift Productivity at PT. Hakim Bima Prima. Utilizing the OEE measurement method to analyze the forklift's performance in terms of availability, performance, and quality. The research shows that by applying OEE, the efficiency of forklift usage can be significantly improved. The practical implication of this study is the increased forklift productivity and reduced maintenance costs. The implementation of OEE on forklifts can be an effective strategy to enhance efficiency and productivity in the company's environment. The objective of this research is to evaluate forklift performance using OEE as the primary framework. Data collection methods involve monitoring operational time, non-productive time, and the success rate of forklift missions from March 2023 to July 2023. The results demonstrate that OEE can be effectively used to identify the primary causes of downtime and optimize forklift usage. The main causes of downtime include maintenance, operational disruptions, and unbalanced workloads. By implementing improvements based on OEE findings, forklift productivity significantly increased, with an average improvement of over 80% during the research period. The application of OEE on forklifts offers manifold benefits, including reduced maintenance costs, increased operational uptime, and more efficient resource utilization. This study provides valuable insights for companies relying on forklifts in their operations, emphasizing the importance of equipment performance monitoring and analysis to enhance overall productivity and efficiency

Abstract

The oil that is so widely circulated on the market and so many advertisements placed in the TV media makes us as consumers confused about what kind of oil is suitable for use in the daily life of consumers The purpose of this research is to find out how far the maximum mileage of each viscosity value in the oil that is tested for different viscosity levels is also when using fuel with different octane values. After trying all the oils that I used during the testing process, it can be concluded that the oil that has a viscosity code SAE 20w-50 is more efficient in fuel use than oil with viscosity codes such as 10w-30 and 15w-40, the results that I obtained the longest distance by using 1 liter of fuel consumption, the farthest distance that can be traveled with fuel with 88 octane, which is 54.3 Km at a speed of 40 km/h and fuel consumption rate each hour is 0.740 liters/hour and for a speed of 60 km/h and 80 km/h the distance that can be traveled is 52.1 Km and 47.7 Km fuel consumption is 1,174 liters/hour and 1,711 liters/hour and for fuel use with an octane value of 95 which is 63.4 km at a speed of 40 km/h and for a speed of 60 km/h and 80 km/h 59.6 Km, fuel consumption per hour is 0.637 liters/hour and 1.015 liters/hour and 1.0882 liters/hour respectively that here seen that the faster a vehicle will be the greater the fuel consumption that will be used.

Abstract

This test was conducted to determine the comparison of torque on a 115 cc motorcycle, Standard with different pully degree variations, 14 °, 13.5 °, 13 °, 12 °. With the maximum speed in each different pully test, at the 14 ° degree pully the resulting torque is averaged 6.35 with Rpm 6,637 (The trotle opening is maximum), In the 2nd test using Pully 13.5 ° testing was carried out with Rpm at 5. 900 - 5,980 (Maximum trotle gas opening) produced a torque of 6.47 which is greater than the test using the previous 14 ° pully, but the maximum Rpm produced by the pully with a degree of 13.5 ° mala is slower than testing using a 14 ° pully. From this test, we can see the difference. That using Pully 13.5° the torque is greater but the engine rotation is slower. The 3rd test using a 13 ° pully with a maximum Rpm at 6,500 - 6,700 (maximum trotle opening) produces a torque of 6.29, from this test it can be seen the difference in torque and Rpm produced by a 13.5 ° degree pully with a 13 ° degree pully, where the Rpm is 720 Rpm faster with a difference in torque at a lower rate of 0.18 Nm isbanding diangaka difference with a 13.5 ° degree pully. The 4th test using a 12° pully with a maximum Rpm at 7,140 - 7,190 Rpm (Maximum Gas Trotle Opening) produced a torque of 6.02. From this test, it can be seen the difference with the test using a 13° pully, where the Rpm produced is higher but the torque is smaller, the torque difference is 0.27.
