Abstract

Centrifugal pumps are one type of pump that is widely used in industry and everyday life. This learning media is designed to provide a comprehensive understanding of the working principles, components, and applications of centrifugal pumps. In the working principles section, it is explained how centrifugal pumps move fluids using centrifugal force generated by a rotating impeller. Fluids enter through the inlet and are accelerated by the impeller, then released through the outlet with higher pressure. The main components of centrifugal pumps such as impellers, casings, shaft seals, and bearings are also explained in detail. Each component has an important function and role in pump efficiency and performance. In this final project, the author developed a learning media for pump disassembly and assembly to meet the material achievements in the syllabus. The methods used in this final project are data collection, identification of component needs, development of plans, creation of learning media, trial of learning media and implementation. After the development of learning media, it is hoped that the learning of the practical course on pump component disassembly and assembly and repair can be met so as to increase knowledge and understanding as well as skills for students.

Abstract

This study aims to analyze and repair damage to the Fehlmann P18s milling machine No. 04 used in the Mechanical Laboratory of Polman Babel. The machine was inoperable due to electrical system failure and a malfunction in the Quick Tool Change System (QTCS). A Root Cause Failure Analysis (RCFA) method using the 5 Why analysis was applied to identify the root causes. The investigation revealed failures in electrical components such as contactors, selector switches, push buttons, fuses, capacitors, and diodes caused by unstable current. Furthermore, the QTCS could not clamp the tool holder properly due to corrosion on spindle components, bearings, and housing. The repair process involved replacing and cleaning damaged parts, followed by re-testing including geometric and functional tests. The testing showed that the machine was successfully restored to its operational state and complied with geometric precision standards. As a preventive measure, a time-based preventive maintenance plan was developed for both the electrical system and the QTCS to avoid recurring failures. This project proves that the RCFA method is effective in analyzing machine issues systematically and comprehensively.

Abstract

The carbon steel chosen for this research is S55C steel which is medium or medium carbon steel. The hardening process is a heat treatment process carried out with the aim of increasing the natural hardness of metal or steel. This process is carried out at high temperatures, namely at the austenization temperature which is used to dissolve cementite in austenite which is then quenched quickly. The method used in this research is experimental. The parameters used in this research were temperatures of 880°C, 950°C, and 1020°C and used seawater, salt water, and oil as cooling media. Based on the hardness test results after the hardening process, the combination of temperature 1020°C and sea water produces the lowest average hardness, namely 24.8 HRC, and the combination of temperature 1020°C and salt water produces the highest average hardness, namely 40.

Abstract

 The oil-draining machine at UMKM Jabal Dinar experienced excessive vibration issues, rendering it inoperative for approximately four years. This problem impacted the quality of the spinach chips produced. This study aims to identify the main causes of unstable vibrations in the oil-draining machine, analyze their effects on product quality, and develop improvement strategies to enhance the machine's vibration stability. The method employed was experimental, with initial vibration measurements reaching 20,83 mm/s, classified in Zone D (red) according to the ISO 10816-3 standard, indicating very high vibrations that could lead to severe damage if not addressed. Modifications were made by replacing the shaft, bearings, and pulleys, as well as performing proper alignment. The improvements resulted in a significant reduction in vibration, positively impacting product quality and extending the machine's lifespan. The study concludes that component modifications and alignment corrections effectively reduced excessive vibrations in the oil-draining machine, ultimately increasing production efficiency and reducing damage to the spinach chips.

Abstract

Purpose of the study: This study aims to optimize the heat treatment process of S55C medium-carbon steel by examining the combined effects of austenitizing temperature, quenching media, and tempering temperature on impact toughness. Methodology: An experimental approach was employed using quenching and tempering treatments. Quenching was performed at three austenitizing temperatures (950°C, 1000°C, and 1050°C) with three different cooling media—salt water, oil, and seawater—followed by tempering at 100°C, 200°C, 300°C, and 400°C. All heating processes were conducted in an electric furnace. Parameter optimization was carried out using the Taguchi method with an L9 orthogonal array. Mechanical performance was evaluated through Charpy impact testing, and confirmation experiments were conducted to validate the optimal parameter combination. Main Findings: The Taguchi analysis identified the optimal quenching condition at an austenitizing temperature of 1050°C with salt water as the cooling medium, yielding the highest impact toughness. Confirmation tests supported the reliability of this result. Additionally, the tempering process showed that increasing the tempering temperature decreased hardness while significantly improving toughness, indicating effective stress relief and improved ductility in the steel microstructure. Novelty/Originality of this study: The novelty of this study lies in the integrated optimization of quenching temperature and diverse cooling media, including seawater, using the Taguchi method, with a specific focus on toughness rather than hardness alone. This research provides new insights into tailoring heat treatment parameters for S55C steel to achieve superior impact resistance, offering practical guidance for more efficient and application-oriented heat treatment strategies in manufacturing industries.
