Abstract

Hospital food distribution requires a system capable of maintaining food temperatures to meet safety standards until the food reaches the patient. Temperature drops during distribution can compromise food quality; therefore, an automated heating system with real time monitoring capabilities is essential. This study aimed to design and construct an Internet of Things (IoT) based heated food trolley utilizing an ESP32 microcontroller, a DHT22 sensor, a PTC heater, an axial fan, and a Fuzzy Logic Controller (FLC) method. The monitoring system employs the Blynk application, enabling temperature and humidity tracking via smartphone. The research methodology encompassed requirements identification, mechanical and electronic design, software development, FLC implementation, system assembly, and performance testing. Test results demonstrated that the system successfully reached a setpoint temperature of 61°C and achieved stability within approximately 10 seconds. The DHT22 sensor exhibited an accuracy rate of 99.1-99.9% when compared to a reference measuring instrument. The FLC implementation effectively automated the PTC heater's operation to maintain the desired temperature range, while the Blynk application successfully displayed real-time temperature and humidity data. The findings indicate that the developed system is capable of maintaining food temperatures during distribution and offers superior monitoring convenience compared to systems relying solely on heating elements without IoTbased monitoring.

Abstract

The increasing demand for clean water requires a monitoring system that is more accurate and practical. Manual water meter recording still has several weaknesses, such as delayed readings, possible recording errors, and the lack of real-time monitoring. This study discusses the design of an Internet of Things (IoT)-based automatic water meter reading system using a flow meter sensor to measure water flow rate and volume. The system was developed using a YF-S201 flow meter sensor, an ESP32 microcontroller, and the Blynk application as a monitoring platform. The research process includes hardware design, microcontroller programming, sensor testing, and result analysis. The test results show that the system can display flow rate, water consumption volume, and estimated usage cost in real-time through the Blynk application. The system also produces readings that are fairly close to those of a conventional water meter. Therefore, the developed system can be an alternative solution to support water usage monitoring in a more efficient and remotely accessible way.

Abstract

The spindle braking system is one of the most important components in a milling machine because it stops spindle rotation immediately after machining. Failure of the braking system reduces operational safety, decreases machining efficiency, and accelerates component wear. This study aims to identify the root cause of spindle braking system failure in an Ajax Model N°2A MKV milling machine using the Root Cause Analysis (RCA) method with the 5 Why approach. Data were collected through direct observation, machine manual review, electrical testing using a multimeter, and systematic root cause analysis. The results indicate that the braking system failed due to a short circuit in the electromagnetic motor coil, causing excessive current in the AC-to-DC braking circuit. Consequently, the bridge rectifier diode and fuse repeatedly failed. The root cause was identified as coil deterioration caused by prolonged service life. The 5 Why method effectively identified the root cause and provided a basis for corrective actions and preventive maintenance to improve machine reliability.

Abstract

Surface grinding constitutes a vital machining process for producing components with high geometric surface quality, with spindle condition serving as the principal factor governing the final machining outcome. This study sets out to evaluate the performance of the spindle on a Reform PSGS-4070 AH surface grinding machine through vibration analysis, while also examining its relationship with surface roughness. An experimental approach was adopted by varying the depth of cut across five levels, with vibration recorded in the horizontal and vertical directions using a Vibroport 80, and surface roughness assessed using a Mitutoyo SJ-210 Surface Roughness Tester. The findings reveal that horizontal vibration rose sharply as the depth of cut increased, moving from Zone A (good) to Zone B (requiring attention) under ISO 10816-3, whereas vertical vibration stayed comparatively steady within Zone A throughout the trials. The resulting spectral pattern points to unbalance in the rotating element along with an early sign of disturbance in the bearing. Horizontal vibration showed a closer relationship with surface roughness than vertical vibration, whose relationship was weaker and less consistent. The safest machining condition was attained at a low depth of cut (≤0.050 mm), yielding the lowest vibration level together with consistently good surface quality.

Abstract

The screw press machine is a main piece of equipment in the palm oil processing process, functioning to extract oil from palm fruit. Machine damage can reduce productivity, increase downtime, and disrupt the production process. This final project aims to identify damage to the screw press machine at PT. Gunung Sawit Bina Lestari, analyze the causes of damage using the 5 Why method, and implement corrective maintenance as a repair action. The method used is descriptive with a case study approach. Data were obtained through observation, interviews, documentation, and literature study. The results showed that the main damage occurred to the screw press, bushing hollow lengthening, and hydraulic motor rubber coupling. The 5 Why analysis showed that screw press damage was caused by excessive workload and the component's service life approaching the hour meter limit, bushing damage was caused by insufficient lubrication and the absence of scheduled maintenance, while rubber coupling damage was caused by hydraulic pressure exceeding the standard. Corrective maintenance was carried out through disassembly, inspection, cleaning, lubrication, replacement of damaged components, and machine testing. The repair results showed that the machine returned to stable operation, vibration was reduced, the hydraulic system functioned normally, and the pressing process operated properl.

Abstract

This research aims to design and build a microcontroller-based testing tool for timer and contactor contacts, specifically to detect NO and NC contact conditions and to verify ON-delay and OFF-delay timer functions more easily, quickly, and accurately than manual methods. The developed device utilizes a microcontroller and components such as relay modules, push-buttons, and LEDs to automatically test NO and NC contact states and monitor timer functions. The system operates by applying a test signal to the contacts under inspection, reading changes in load current and voltage, and displaying test results in real-time. Research results demonstrate that the device effectively detects contact conditions, displays status information instantly, and measures time delays with millisecond precision. Furthermore, the device identifies faulty or unstable contacts, thereby facilitating the analysis of component conditions. Based on testing outcomes, the tool is considered more practical, rapid, and efficient than manual testing using a multimeter. Thus, the designed microcontroller-based testing tool successfully meets the research objectives and holds potential for use as an aid in laboratory practice, education, and electrical equipment maintenance.

Abstract

Alternative energy utilization continues to develop, yet unoptimized potential remains, such as mechanical energy from children playing on swings in playgrounds. This energy can be converted into useful electricity through a conversion device. This study aims to design a motion-to-electricity conversion system for 12 V battery charging and monitoring using Arduino Uno. The methodology includes design, assembly, testing, and analysis. The system comprises a generator, rectifier, buck converter, battery, voltage sensor, ACS712 current sensor, I2C LCD, LED, and relay. Test results show the generator produces 0.07–1.19 V and 0 A, failing to charge the battery optimally. Average errors are 2.65% for voltage and 8.61% for current sensors. The monitoring system successfully displays data on the LCD and operates the LED and relay. In conclusion, the system functions properly, but a more suitable generator is required.
