Abstract

Impact Test can be interpreted as a test that measures the ability of a material to accept impact loads which are measured by the amount of energy required to break the specimen with a swing. The aim of this test is to determine the effect of temperature on the value of energy absorbed by the material and the impact value. The method used in this research is the experimental method, namely the method used to find the effect of temperature on the impact strength of charpy and izod. The results of the charpy and izod impact tests on ST37 Steel specimens prove that there is an influence of temperature on the charpy and izod impact tests. Where the higher the temperature, the higher the energy absorbed and the impact price. Conversely, the lower the temperature, the energy absorbed and the impact price will be lower. In the test results, the lowest energy absorbed in the charpy impact test was 76 J and 22 J in the izod impact test, while the highest energy absorbed in the charpy impact test was 245 J and 114 J in the izod impact test. The lowest impact price in the test was 0.1727 J/mm2 for the charpy impact test and 0.037 J/mm2 for the izod impact test, while the highest impact price in the test was 0.5568 J/mm2 for the charpy impact test and 0.19 J/mm2 for izod impact testing.

Abstract

This study presents the design, fabrication, and performance analysis of a SolidWorks-based disk mill coffee grinder specifically developed for Micro, Small, and Medium Enterprises (MSMEs) in Indonesia's expanding coffee industry. Addressing the technological gap between industrial-scale equipment and small-enterprise operational constraints, the research employed parametric 3D modeling and virtual assembly simulation to optimize machine configuration prior to physical fabrication. The design integrates a 5.5 HP gasoline engine with a 3:1 pulley reduction system, angle iron frame structure (600×600×730 mm), and adjustable pin-type grinding disks to achieve targeted processing capacity and particle uniformity. Performance testing demonstrated that the machine successfully processes 1 kg of roasted coffee beans in approximately 8 minutes, yielding a theoretical throughput of 30 kg/hour with consistent particle distribution suitable for various brewing methods. Material loss was maintained below 2%, while operational vibration and noise levels remained within acceptable limits for workshop environments. The SolidWorks-driven design methodology significantly reduced material waste and iterative physical modifications by enabling early detection of interference conflicts and spatial optimization during the digital prototyping phase. These findings confirm that CAD-integrated engineering approaches can effectively support the development of cost-effective, maintainable, and scalable processing equipment tailored to MSME requirements. The resulting disk mill configuration offers a practical solution for enhancing product consistency, operational efficiency, and competitive positioning within Indonesia's decentralized coffee value chain, while providing a replicable framework for localized agricultural machinery innovation.
