Abstract

Objective: T-shirt screen printing ink drying can be done with various methods and tools such as fans, hair dryers, or heatguns. Although common and easy to do, these methods of drying t-shirt screen printing ink are less effective and efficient because they take a long time and the drying results are uneven. This research aims to make an effective and efficient plastisol screen printing ink dryer with flash curing using the research and development method. Method: This research aims to make an effective and efficient plastisol screen printing ink dryer with flash curing using the research and development method. Results: The results showed that the drying process with the tool made took 20 seconds for each shirt, 5 seconds faster than the ink drying test with the manual method. The tool made uses a synchronous motor to move the infrared heater forward and backward so that the ink drying results can be evenly distributed. Novelty: This research aims to make an effective and efficient plastisol screen printing ink dryer with flash curing using the research and development method.

Abstract

This study aims to design and evaluate an automatic infrared therapy system capable of maintaining temperature stability within a safe and controlled range. The system utilizes a non-contact infrared temperature sensor MLX90614, an ultrasonic distance sensor HC-SR04, an Arduino Uno microcontroller, and an infrared lamp regulated by a pulse width modulation (PWM) signal. Temperature control is implemented using a proportional control (P-Control) method, while sensor data is processed using a moving average filter to reduce measurement noise. Experimental testing was conducted by comparing system responses without control and with P-Control at three distance variations, namely 15 cm, 30 cm, and 45 cm. The results show that the uncontrolled system produced a temperature deviation of ±1.8°C, while the implementation of P-Control reduced the deviation to ±0.6°C at a setpoint of 45°C. However, the achieved average temperature varied depending on distance, with values ranging from 35.27°C to 42.61°C across all test conditions. These results indicate that the application of P-Control combined with a moving average filter is effective in improving temperature stability, although the heating performance is influenced by the distance between the sensor and the object. This system demonstrates potential for safer and more controlled infrared therapy applications.

Abstract

General Background: Stroke remains a major health problem, and continuous monitoring of motor function is important for assessing patient rehabilitation progress. Specific Background: Hand grip strength is commonly used to evaluate motor conditions in post-stroke patients; however, previous measurement systems either required manual patient data recording or relied on limited-capacity local storage. Knowledge Gap: Existing hand grip measurement devices have not adequately provided integrated patient identification and cloud-based data storage for long-term monitoring. Aims: This study aimed to develop a hand grip strength measurement system for stroke patients using Internet of Things (IoT) technology, RFID-based patient identification, and Google Spreadsheet cloud storage. Results: The proposed system utilized an ESP32 module, RFID-RC522, load cell sensor, HX711 module, and LCD display. Testing showed a load cell error rate of 0.3%, an average RFID data transmission delay of 3.4 seconds, and an overall system error of 1.09% based on measurements from 10 stroke patients compared with a CAMRY Hand Dynamometer Model 101. Measurement results were automatically stored in Google Spreadsheet and could be accessed by healthcare providers and patient families. Novelty: The system integrates hand grip assessment, RFID-based patient identification through E-KTP, and cloud-based data storage within a single IoT platform. Implications: This design provides a practical approach for structured and accessible monitoring of hand grip strength data in stroke patient therapy programs.Highlights: Sensor calibration testing produced a measurement error of only 0.3%. RFID-RC522 transmitted patient identification data with an average delay of 3.4 seconds. Comparison with a commercial dynamometer showed a mean system error of 1.09% across ten participants.
