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 has driven transformation across various sectors, including education. Understanding IoT—particularly through the use of microcontrollers such as Arduino—has become an essential skill that should be introduced early to students in preparation for the challenges of the Fourth Industrial Revolution. An Arduino workshop held at SMA Negeri Ambulu Jember aimed to enhance students’ understanding and skills in technology, especially in the context of IoT applications. The activity employed an experimental learning approach using Arduino microcontrollers and various sensors, including the DHT11 (temperature and humidity), HC-SR04 (ultrasonic distance), and LDR (light intensity). Through hands-on practice, students were introduced to basic IoT concepts, microcontroller programming, and sensor data integration and analysis. The evaluation results showed significant improvements in students’ cognitive and psychomotor abilities, as reflected in their capability to design and implement sensor-based systems independently. This workshop demonstrated that project-based and hands-on learning methods are effective in fostering interest and improving technological literacy among high school students.

Abstract

Tujuan dari penelitian ini untuk mengeksplorasi pengaruh digital minimalism dan motivasi belajar terhadap prokrastinasi akademik di kalangan mahasiswa. Dalam era digital saat ini, fenomena prokrastinasi akademik semakin meningkat, di mana mahasiswa sering kali terjebak dalam penggunaan teknologi yang berlebihan dan distraksi yang dapat mengganggu proses belajar. Dengan menggunakan pendekatan kuantitatif, data dikumpulkan melalui kuesioner yang dibagikan kepada mahasiswa. Penelitian ini menunjukkan ada pengaruh signifikan digital minimalism dan prokrastinasi akademik dengan nilai sig. 0,000, terdapat pengaruh signifikan motivasi belajar pada prokrastinasi akademik dengan nilai sig. 0,030, serta terdapat pengaruh simultan antara digital minimalism dan motivasi belajar pada prokrastinasi akademik dengan nilai sig. 0,000. Temuan ini diharapkan dapat menjadi referensi bagi mahasiswa dan institusi pendidikan dalam mengatasi prokrastinasi akademik dan meningkatkan efektivitas pembelajaran.

Abstract

This study aims to optimize CNC toolpath strategies using Grey Relational Analysis (GRA) to enhance machining efficiency. Five toolpath strategies—Zigzag, Constant Overlap Spiral, Parallel Spiral, One Way, and True Spiral—are systematically evaluated based on spindle speed, feed rate, depth of cut, and step over, assessing their impact on machining performance.The machining process is conducted using a 3-axis CNC milling machine equipped with a 10 mm diameter endmill tool. Data collection is performed through Mastercam software, where numerical simulations precede the application of Grey Relational Coefficient (GRC) and Grey Relational Grade (GRG) computations to determine the optimal toolpath strategy.The results indicate that the Zigzag toolpath, configured with a spindle speed of 1300 RPM, feed rate of 700 mm/min, depth of cut of 0.8 mm, and step over of 8 mm, achieves the highest GRG value, signifying superior machining efficiency. Further analysis demonstrates that optimizing toolpath parameters significantly enhances process stability, reduces energy consumption, and shortens production cycle time, contributing to increased productivity in CNC machining operations. These findings provide valuable insights for the manufacturing industry, presenting a data-driven framework for selecting optimal toolpath strategies to improve machining precision, operational cost efficiency, and sustainable production practices.

Abstract

This study aims to see the partial effect of the use of e-learning and independent learning on the learning outcomes of introductory economics and business statistics with motivation as a mediator. The type of research used is quantitative with a survey method. Samples were taken using the Slovin formula and obtained as many as 96. The analysis used was path analysis. The research results obtained include; 1) the use of e-learning has a significant effect on motivation because the value of sig. 0.000; 2) learning independence has no significant effect on motivation with sig. 0.645; 3) the use of e-learning has a significant effect on learning outcomes with sig. 0.007; 4) learning independence has a significant effect on learning outcomes with sig. 0.000; 5) motivation has a significant effect on learning outcomes with sig. 0.000; 6) learning motivation can mediate the effect of using e-learning on learning outcomes with a value of Z = 4.89; 7) learning motivation cannot mediate the influence of independent learning on learning outcomes with a value of Z = 0.4572. Further research still needs to be done using other relevant variables.

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.
