Abstract

This study develops a lathe machine inspection standard based on critical component analysis and Mean Time Between Failure (MTBF) to support preventive maintenance. A mixed-method approach was applied through observations, interviews, and historical failure data analysis of the CW 62110B lathe at PT Bahari Makmur Sejahtera from March 2025 to April 2026. Critical components were identified based on failure frequency, downtime, production impact, and maintenance complexity. The results identified six critical components with an MTBF of 220.8 operating hours. The proposed inspection standard defines inspection parameters, methods, inspection frequency, and maintenance actions, and was validated using historical failure data and the principles of ISO 17359:2018.

Abstract

Consistent basic maintenance is required to maintain lathe condition. This study evaluates the actual routine maintenance condition of a lathe at the Workshop of PT Bahari Makmur Sejahtera based on Autonomous Maintenance standards. A descriptive approach was used through observation, interviews, documentation, initial cleaning, identification of abnormalities and contamination sources, and analysis of standardization needs. Observations revealed accumulated chips, dust, and lubricant residue, the absence of maintenance standards, a non-functioning automatic feed handle, and an improperly aligned machine table. These findings formed the basis for recommendations covering maintenance areas, methods, frequencies, criteria, corrective actions, and responsibilities. The evaluation identified a gap between the actual condition and the characteristics of structured Autonomous Maintenance. Follow-up recommendations include standardization of cleaning, lubrication, inspection, checklists, and abnormality identification as a basis for autonomous lathe maintenance.

Abstract

Table slide jamming on the Reform HR PSGS-4070AH surface grinding machine can reduce machining quality, disrupt laboratory activities, and increase the risk of component failure. This study aimed to identify the root cause of table slide jamming using the Root Cause Failure Analysis (RCFA) method. Data were collected through observation, interviews, component inspection, and documentation, and subsequently analyzed using the Fishbone Diagram and 5 Why Analysis. The results revealed that the root cause was not the failure of the ball screw, but the absence of a consistent preventive maintenance program, resulting in an ineffective central lubrication system. The proposed corrective actions include restoring the lubrication system, replacing damaged components, and implementing a preventive maintenance program to improve machine reliability.

Abstract

Whiteboards serve as the primary instructional medium in classrooms. However the manual cleaning process often wastes time. To address this issue, an automated whiteboard eraser system for a 50x70cm board was developed using the Research and Development (R&D) method, with a system cleanliness rate reaching 95% in erasing writings on the whiteboard. The device relies on motor dynamos to drive its horizontal and vertical movement mechanisms. To restrict the erasing range while calibrating the initial position, the systems utilizes two limit switches (NO and NC). Test results indicate successful integration of all components. The device evenly sweeps the board surface within a single operational cycle and automatically returns to its initial position, making the learning process both efficient and hiegenic.Performance testing indicates that the average duration of the sweeping movement varies between 3 to 23 seconds depending on the tested cycle variation and mechanical direction.

Abstract

Rusip fermentation is a traditional fish fermentation process whose quality is influenced by temperature, humidity, light intensity, and gas concentration. Conventional manual monitoring makes the fermentation process less effective. This study aims to develop an Internet of Things (IoT)-based monitoring and control system for rusip fermentation using an ESP32 microcontroller. The system integrates a DHT11 sensor for measuring temperature and humidity, an MQ-135 sensor for gas detection, a GY-30 (BH1750) sensor for measuring light intensity, and an I2C LCD, Telegram, and Blynk for real-time monitoring. Sensor performance was evaluated by comparing the DHT11 with a UT333 Mini Temperature Humidity Meter and the GY-30 with a Benetech GM1030C Lux Meter. The results showed measurement differences of 0.2°C for temperature, 3% RH for humidity, and 0.9 Lux for light intensity. One-week monitoring showed temperatures ranging from 28.70°C to 30.06°C, humidity from 83.40% to 87.70% RH, light intensity from 3.33 to 51.67 Lux, and gas concentration from 1,038 to 1,487 ppm. The proposed system successfully performed real-time monitoring and control, enabling users to remotely monitor the rusip fermentation process.

Abstract

The Aciera F3 milling machine is a vital tool in practical and production activities at the Mechanical Engineering Laboratory of the Bangka Belitung State Manufacturing Polytechnic. Damage to the electrical system resulted in the machine being unusable, which hampered the learning process. This study aims to identify the source of the damage and determine the appropriate repair method. The strategy implemented is Root Cause Analysis (RCA) with the 5 Whys method. Data were collected from interviews with technicians, literature studies, maintenance and repair records, and manuals. The research findings indicate damage to the vulnerable auxiliary contactor and broken terminals, resulting in a power outage to the control panel. The 5 Whys analysis indicates that the old component life and lack of regular replacement are suspected to be the main causes of the auxiliary contactor damage.

Abstract

A growth spurt is a developmental phase experienced by infants, characterized by increased crying frequency, changes in sleep patterns, and heightened nutritional needs. Parents often struggle to distinguish between crying caused by a growth spurt and crying due to hunger, a wet diaper, or other forms of discomfort. Therefore, this study aims to design and build an infant cry detection system to automatically indicate when a growth spurt is occurring. The developed system utilizes an ESP32 as the main microcontroller and a sound sensor (microphone) as the input to detect the intensity of the infant's crying. Sensor data is processed by the ESP32 based on pre-programmed parameters to determine the likelihood that the infant is experiencing a growth spurt. Detection results are displayed on a 16×2 LCD with an I2C interface, ensuring the information is easily readable for the user. Additionally, an active buzzer serves as an audible indicator when the system detects conditions meeting the growth spurt criteria. The entire circuit is powered by a power bank, making the system portable and suitable for use in various locations.

Abstract

This study aims to design a prototype of an Internet of Things (IoT)-based booster pump monitoring and control system using ESP32 to support water distribution in multi-story buildings. The system consists of an ultrasonic sensor, pressure sensor, flow meter, BTS7960 driver, relay, 20×4 I2C LCD, and the Blynk app as a medium for remote monitoring and control. The research methods include system design, implementation, and testing. The test results showed an average accuracy of the ultrasonic sensors at 93.62% and 95.16%, while the automatic control function, manual control via Blynk, and system parameter monitoring achieved a 100% success rate. These results indicate that the system can monitor water distribution conditions in real-time and control pump operations both automatically and manually, thus improving the effectiveness of IoT-based water distribution management.

Abstract

The development of Industry 4.0 has shifted maintenance strategies from corrective maintenance to predictive maintenance based on machine condition monitoring. Vibration analysis is widely used to detect machine failures before unexpected breakdowns occur. However, limited learning media in predictive maintenance courses reduce students' practical understanding of bearing fault characteristics. This study aims to design a vibration-based bearing fault simulation learning media to support practical learning activities. The research methods include data collection, tool design, manufacturing, assembly, and testing. The developed system consists of an AC motor, shaft, coupling, bearing housing, speed controller, and bearings with several fault conditions. The results indicate that the system can simulate inner race, outer race, and rolling element defects, producing different vibration characteristics. Therefore, the proposed learning media can improve students' understanding of predictive maintenance and vibration analysis in a practical manner.
