Abstract

Handling metal cutter debris in the tissue processing industry poses a significant risk of physical injury, compromising Occupational Health and Safety (OHS). To address this issue, this research aimed to design, build, and test the functionality of a remote-controlled prototype for detecting and collecting metal fragments. This study applied a Research and Development (R&D) methodology, resulting in a Robot Unit (Receiver) equipped with an SN04-N2 metal proximity sensor, an HC-SR04 ultrasonic sensor, and an electromagnet-based collection mechanism. Operational control was performed via a Control Unit (Transmitter) using the ESP-NOW wireless communication protocol. The test results show that the device characteristics include a stable communication range of up to 220 meters in an outdoor environment. The metal detection limit is effective at a 3 mm distance, with an electromagnetic mechanism capable of lifting a maximum load of 41.2 grams at a lifting distance of 0.3 cm. However, the operational endurance of the Receiver Unit is recorded at 1 hour and 34 minutes. From these results, the conclusion of this study is that the prototype successfully functions as intended, with reliable communication and actuator strength as its main advantages. However, power efficiency and the challenge of precise remote positioning are its primary limitations that require further development.

Abstract

In the era of agricultural digitalization, dependence on Internet of Things (IoT) technology is increasing, yet supporting infrastructure remains vulnerable to connectivity disruptions. This research aims to develop an alternative protocol for IoT-based agricultural systems that can operate during internet connection failures, focusing on implementing a failsafe mode using NodeMCU ESP8266. The research methodology includes developing a monitoring system using soil moisture sensors and ultrasonic sensors for water level detection, as well as performance evaluation based on decision-making accuracy parameters, mode transition response time, and consistency in water management. Implementation results showed a 40,1% reduction in water consumption compared to traditional irrigation methods. The failsafe mechanism demonstrated sustained operations with 98% reliability in maintaining optimal soil moisture levels during 72-hour offline periods. This research contributes significantly to the development of smart agriculture through a cost-effective and scalable solution, particularly for areas with limited infrastructure that only require basic internet connectivity and minimal maintenance.
