Abstract

Preventive maintenance is an activity to maintain the condition of the machine that is carried out in a planned/scheduled manner. Preventive maintenance itself includes scheduling, implementation, and improvement/modification. The purpose of this research is to carry out preventive maintenance on machine tools to maintain optimal engine conditions, ensure machine availability and reduce maintenance costs to a minimum. The preventive maintenance system design method is based on machine condition data collected by observing related machines and interviewing informants at SMKN 2 Pangkalpinang. Data from observations and interviews were used to calculate and determine the value of machine complexity so that a lathe maintenance system was obtained in the form of preventive maintenance design schedule data, annual preventive maintenance schedules, work specifications, and control cards. The results showed that the recommended preventive maintenance system design was acceptable to be implemented on lathes at SMKN 2 Pangkalpinang within 2 years. Further research is needed to increase the effectiveness of this preventive maintenance system. Some things that need to be further developed include a system for managing materials and machine parts inventory and changing engine oil using the oil listed in the lubrication table.

Abstract

The construction of the body of minibus passenger vehicles usually uses walls, roofs and floors called vehicle panels. The vehicle panel itself is the most important part that supports safety and comfort for the occupants of the vehicle. Generally, the vehicle panel will cause a sound that makes passengers uncomfortable because of the noise that occurs due to the vibration of the vehicle engine and damaged road conditions. Excessive vibration can be reduced by increasing the rigidity of the panel by changing the shape such as beads, embossing, stiffeners, spot welded stiffenes, and grooves. The purpose of this study was to determine the effect of borehole variation and the number of dimple holes on plate stiffness for its natural frequency response. This research method is shown as follows: making experimental designs, dimple manufacturing processes, measuring and analyzing the results of dimple-shaped plates with variations in boreholes and the number of dimple holes to stiffness for their natural frequency response response. Based on the results, the number of holes on the dimple plate affects the stiffness of the plate to its natural frequency response.

Abstract

Condition-Based Monitoring (CBM) merupakan metode pemeliharaan prediktif yang mengandalkan pemantauan parameter operasional untuk mendeteksi dini potensi kerusakan. Penelitian ini mengembangkan model CBM multi-parameter untuk memantau kondisi pompa sentrifugal pada sistem distribusi air bersih. Parameter yang diamati mencakup getaran, suhu, dan tekanan, yang dikumpulkan secara berkala dari empat unit pompa. Pengukuran dilakukan menggunakan vibration meter, infrared thermometer, dan manometer. Data dianalisis untuk mendeteksi tren degradasi dan anomali operasional. Hasil penelitian menunjukkan bahwa suhu dan tekanan pada beberapa pompa mengalami fluktuasi, sedangkan nilai getaran tetap berada dalam ambang batas aman. Pompa dengan suhu dan tekanan tidak stabil berpotensi mengalami degradasi performa yang lebih cepat. Penerapan CBM memungkinkan deteksi dini terhadap potensi kegagalan, sehingga dapat mengurangi risiko downtime dan meningkatkan efisiensi pemeliharaan. Studi ini menekankan pentingnya pemantauan berbasis kondisi dalam menjaga keandalan sistem distribusi air bersih, terutama di lingkungan pendidikan yang memiliki keterbatasan anggaran pemeliharaan. Penelitian ini merekomendasikan pemantauan jangka panjang serta analisis lebih lanjut terhadap hubungan antara performa pompa dan konsumsi energi.

Abstract

Damage to the electrical system of the Aciera F3 milling machine caused the main motor to fail to operate, disrupting practical activities at the Bangka Belitung State Manufacturing Polytechnic. This study aims to identify the root cause of the failure and carry out repairs using the Root Cause Failure Analysis (RCFA) approach with the 5 Why technique. The research stages include data collection through technician interviews, visual inspections, and functional testing of the electrical system. The analysis revealed that the damage resulted from a short circuit in the C2 contactor, caused by component aging and the absence of routine inspections. Corrective action was taken by replacing the damaged contactor and auxiliary contact components. As a preventive measure, an electrical inspection checklist was developed to support scheduled maintenance. Post-repair testing showed that the electrical system functioned normally and the machine could operate according to standard specifications. The application of the RCFA method proved effective in resolving the problem comprehensively and laying the foundation for a reliability-based maintenance system.

Abstract

Preventive maintenance is a method of maintaining machinery before damage occurs. The Yanmar 6AYM-WST engine serves as the driving force for the dredge pump on the Production Suction Vessel (KIP) at PT. Timah Tbk, which sometimes experiences overheating during operation due to an underperforming cooling system. This final project aims to design a preventive maintenance system for the engine’s cooling system. The methods used include observation, interviews, literature study, and data collection of past breakdowns. The outcome of this study includes an annual maintenance schedule, work specifications, control cards, and machine history cards that are structured and ready for implementation. With this approach, it is expected to reduce the frequency of cooling system failures, improve engine reliability, and achieve operational efficiency of the vessel.

Abstract

In traditional PCB layout creation, copper solvent materials like ferric chloride are commonly used along with other processes. This final project focuses on developing a PCB (Printed Circuit Board) milling machine. The machine is designed to engrave electronic circuit layouts onto PCB boards using a CNC (Computer Numerical Control) system. The CNC machine facilitates the precise engraving of circuit layouts on PCB boards. The development of this machine involves several stages, including the design process, hardware assembly, and mechanical system assembly. The machine's control system is operated using an Arduino Mega and RAMPS 1.4, which manage the machine's movements. The machine is equipped with three stepper motors, named Nema 17, which drive the machine along three axes: X, Y, and Z. The CNC machine utilizes a single lip cutter as the engraving tool on the PCB, positioned along the Z-axis. Based on the test results for a 10 mm movement on the X, Y, and Z axes, the average movement deviation was found to be 10.23 mm for the X-axis, 10.59 mm for the Y-axis, and 10.45 mm for the Z-axis.
