Abstract

Electroplating on steel is basically done with the aim of protecting the steel surface from corrosion attack. However, it is necessary to know the quality surface hardness of steel that has undergone electroplating. This research is determining the electroplating time and the best anode and cathode distance to surface hardness in the nickel electroplating process on low carbon steel. The method was done by placing the specimen into a electrolyte solution. Then the hardness test was carried out on the specimen. The results shown that the ST-37 steel coating with nickel with a variation of the plating time of 12 minutes and the distance between the anode and cathode of 150mm,has highest hardness number of 246.7kg/mm2. By ANOVA analysis the coating time greatly affects the surface hardness.

Abstract

This study aims to develop a Python and Gmsh-based program for automating the generation of finite element method (FEM) models and integration with the OpenRadioss solver, enabling more efficient creation of a FEM model for a curved corrugated sandwich structure under projectile impact. Based on the research conducted, the program has been successfully integrated with OpenRadioss and successfully simulated. The simulation results show a graph that closely matches experimental data, indicating that the generated finite element model is acceptable. The time required to generate the model is approximately ±73 s, while conventional methods require at least ±480 s. Additionally, this program has been compared with the latest Graphical User Interfaces (GUI) provided by OpenRadioss, demonstrating the advantages of the developed program in terms of time efficiency, ease of use, and its ability to handle design variations more quickly.

Abstract

This community service program aims to address the problem of excessive oil content in MOCAF dumpling chips produced by the Bawang Ceria Farmer’s Women Group in Banjarnegara. The previous manual draining process was found to be ineffective, causing the product to turn rancid quickly and have a short shelf life. As a solution, the implementation team introduced an oil spinner machine based on a centrifugal system equipped with automatic speed control. The program was carried out through socialization, hands-on training, and a joint technology trial with the member group. The results indicate that the spinner effectively reduced oil content by approximately 10%, producing chips with a crispier texture and a more appealing appearance. The integrated dimmer and automatic timer features ensured stable processing and consistent product quality. Although a slight decrease in savory flavor was noted due to reduced oil content, the overall product remained well accepted by consumers. Furthermore, the training activities significantly enhanced the members’ understanding and technical skills, as reflected in an increase in knowledge level from 24.61% to 80.48%.

Abstract

Corrosion represents a major concern in numerous industrial sectors, primarily due to the inherent vulnerability of metallic structures to degradation. Therefore, implementing effective corrosion protection measures is essential. Naturally occurring organic chemical compounds and important molecules have demonstrated strong potential for corrosion protection. Some studies indicate that those containing oxygen, sulfur, and nitrogen in the atmosphere exhibit the highest protection performance. Organic and naturally derived protection generally functions by forming protective films on metal surfaces, thereby mitigating the corrosion rate. This review emphasizes the role of galvanized coatings as effective corrosion protection with the cathodic protection method and anode sacrificial on the steel surfaces. It also includes an analysis of steel surface morphology using SEM-EDS micrographs. The review was conducted following PRISMA guidelines, with literature sources covering publications. A total of selected studies were critically analyzed to examine corrosion types, protection mechanisms, efficiency performance, and surface characterization of galvanized coatings. Both Hot-Dip Galvanizing (HDG) and Cold Galvanizing Coatings (CGC) were systematically compared in terms of corrosion rate, protective efficiency, coating thickness, and environmental aggressiveness. The paper systematically covers different types of corrosion, available protection control methods, and corrosion mitigation techniques. It further explores protective mechanisms, evaluates efficiency, and identifies the most effective control strategies. Additionally, the review discusses theoretical approaches, activation parameters, adsorption studies, and surface morphology. This review highlights key factors influencing galvanized steel performance, including coating composition, environmental parameters, and exposure duration, while also identifying current research gaps. The findings provide valuable insights for optimizing corrosion protection strategies and improving the service life of steel structures in atmospheric environments.
