Abstract

UMKM Make-D is located in Dieng Kulon Tourism Village, one of the villages in Batur District, Banjarnegara Regency. Potato chips are a typical souvenir from this area, along with the increase in tourist visits in proportion to the demand for potato chips. The production process is still traditional, making it difficult for UMKM to meet customer demand. The goal of the mechanical engineering lecturer community service team is to implement a semi-automatic chopping and frying machine to help speed up the production process of quality fried shallots. The method in this community service begins with identifying partner problems, the next stage is to conduct a group discussion with the community service team to discuss problem solutions, the result of this community service is the application of appropriate technology for semi-automatic chopping and frying machines to improve the potato chip production process.

Abstract

Al-Zn alloys are widely utilized in industries such as automotive, aircraft manufacturing, and advanced military equipment due to their exceptional strength-to-weight ratio. Among various fabrication methods, metal casting is a commonly used technique for producing structural components from these alloys. However, a significant challenge with metal casting is the reduction in mechanical properties compared to the base material before melting. This reduction highlights the need for research to identify the optimal casting conditions, particularly the casting temperature, which plays a crucial role in maintaining and potentially enhancing the material's mechanical properties. Aluminum alloy 7075, known for its high strength, was selected for investigation. According to the Al-Zn phase diagram, the melting point of aluminum alloy 7075, based on the weight percentage specified by the Standard Aluminum Association, is approximately 660°C. Experiments were conducted by varying the pouring temperature during casting in 30°C increments above this melting point. Specifically, the alloy was melted and cast at three different temperatures: 690°C, 720°C, and 750°C. The mold temperature was consistently maintained at 220°C to isolate the effects of the pouring temperature. Results indicate that increasing the casting temperature significantly affects the alloy's microstructure and mechanical properties. As the casting temperature increases, the cooling rate decreases, leading to a finer grain structure. This finer grain size directly contributes to an increase in hardness, suggesting that higher casting temperatures can enhance the mechanical properties of Al-Zn alloys. These findings emphasize the importance of precise control over casting temperatures to optimize the performance characteristics of aluminum alloy 7075 in high-strength applications.
