Abstract

Penelitian ini membahas desain sistem inkubator telur otomatis yang menggunakan teknologi Internet of Things (IoT) terintegrasi aplikasi mobile, dengan tujuan meningkatkan efisiensi dan efektivitas proses penetasan telur. Metode penetasan tradisional sering mengalami tantangan dalam kontrol suhu dan kelembaban, yang dapat mengakibatkan kegagalan penetasan. Dengan memanfaatkan protokol Message Queuing Telemetry Transport (MQTT), sistem ini mampu melakukan pemantauan dan pengendalian suhu dan kelembaban secara real-time. Hasil pengujian menunjukkan bahwa kalibrasi sensor suhu dan kelembaban DHT11 memberikan error maksimum sebesar +1,10, dan otomatisasi relay berhasil menjaga kondisi suhu dan kelembaban optimal. Stabilitas konektivitas MQTT mencapai 99,8%, dengan latency rendah kurang dari 150 ms, yang mendukung komunikasi cepat dan andal antara pengguna dan perangkat. Temuan ini menegaskan pentingnya penerapan teknologi modern dalam budidaya unggas, serta memberikan solusi inovatif untuk meningkatkan praktik penetasan telur.

Abstract

The rapid development of Internet of Things (IoT) technology and smart sensors in the automotive industry opens up great opportunities in the world of education, especially at the high school level. This community service program aims to introduce Arduino-based sensor and microcontroller technology to students of SMAN Ambulu Jember through a workshop approach and project-based learning. The method used in this activity uses the PAR (participatory action research) method with an interactive workshop approach and project-based learning that includes an introduction to types of automotive sensors such as DHT11, HC-SR04, and LDR as well as sensor installation and programming practices. The evaluation results showed a significant increase in students' understanding of the concept of IoT and microcontrollers, as well as a high interest in studying the field. This workshop proves the effectiveness of the interactive learning model in improving students' technological literacy and readiness to face the challenges of industry 4.0.

Abstract

The primary quality indicator of coffee beans is determined by their moisture content. This study aims to develop a portable prototype device for measuring both the moisture content and temperature of coffee beans, utilizing an ESP32 microcontroller integrated with a Capacitive Soil Moisture Sensor v1.0 and an SHT21 sensor. The device is designed to provide accurate and efficient measurements, with results displayed in real time on an OLED screen. In addition, the system stores measurement data on an SD card for further analysis. Experimental testing was conducted five times for each sample, comparing the results of the prototype with reference instruments, namely the YL-69 sensor for moisture measurement and a digital thermometer for temperature measurement. The results demonstrated that the device achieved a high level of accuracy, with an average relative error of 1.05% for moisture content and 0.91% for temperature. Furthermore, the prototype was proven to be portable and energy-efficient, consuming 7.7 Wh over 1.1 hours of operation, as evaluated through battery-based performance testing until full discharge. With its integrated data storage and real-time monitoring capabilities, this device provides a practical solution for coffee farmers and processors in maintaining and ensuring the quality of coffee beans.
