Abstract

This study presents the design and evaluation of an Internet of Things (IoT)-based automated pheromone spraying system for the control of Oryctes rhinoceros in oil palm plantations. The proposed system integrates a microcontroller with an infrared sensor, a load cell, a real-time clock (RTC), a GSM communication module, and an ultrasonic mist generator to support real-time monitoring and automated pheromone release. Experimental procedures included component validation and field testing conducted over a seven-day period. The results demonstrate that the infrared sensor achieved a detection accuracy of 100% under low-light conditions, while the load cell showed a coefficient of variation of approximately 2%, indicating high measurement precision. The GSM module was capable of transmitting data with delays ranging from 0 to 51 seconds over a communication range of up to 5 km. Field evaluation further revealed that the trap positioned at a height of 2.5 meters yielded the highest capture rate of rhinoceros beetles compared to other configurations. Overall, the findings indicate that the developed system is reliable, energy-efficient, and applicable for sustainable pest management in oil palm plantations.

Abstract

Indonesia merupakan salah satu produsen nanas terbesar di dunia, sehingga penentuan tingkat kematangan buah menjadi hal penting untuk menjaga mutu dan mendukung distribusi pascapanen. Penilaian kematangan secara tradisional yang mengandalkan pengamatan visual dan pengalaman petani sering kali bersifat subjektif dan kurang konsisten. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem hidung elektronik multisensor berbasis sensor gas MQ untuk mendeteksi senyawa volatil yang dilepaskan buah nanas selama proses pematangan, serta mengevaluasi kinerja algoritma Random Forest dalam klasifikasi tingkat kematangan. Sistem terdiri atas chamber sampel dan chamber sensor yang dilengkapi lima sensor gas (MQ-2, MQ-3, MQ-4, MQ-5, dan MQ-135), modul ADS1115, serta mikrokontroler ESP32 untuk akuisisi data. Data hasil pengukuran diekstraksi menjadi beberapa parameter fitur sinyal, kemudian dibagi menjadi 70% data latih dan 30% data uji dari total 40 data sampel. Hasil penelitian menunjukkan bahwa sistem mampu mengklasifikasikan nanas ke dalam empat kategori kematangan (mentah, setengah matang, matang, dan terlalu matang) dengan akurasi sebesar 92%, di mana sensor MQ-135 memberikan kontribusi terbesar dalam proses klasifikasi. Temuan ini menunjukkan bahwa kombinasi hidung elektronik multisensor dan Random Forest dapat menjadi metode yang efektif, objektif, dan non-destruktif dalam menentukan tingkat kematangan buah nanas.

Abstract

This community service programme aimed to strengthen physics laboratory management and practical activities at three senior and vocational secondary schools in Pekanbaru, Indonesia. Conducted by lecturers and students of the Physics Study Programme, Universitas Muhammadiyah Riau, the programme involved partner assessment, orientation, implementation, and evaluation. Activities included developing Standard Operating Procedures (SOPs), inventorying laboratory equipment, preparing practical modules based on real experiments and PhET virtual simulations, and conducting practical training. Programme outcomes were evaluated through questionnaires administered to students and supervising teachers. Before the programme, 60% of students had never participated in physics practical activities. Following the intervention, all students (100%) reported improved understanding of the practical materials, with 20% reporting very good understanding, 33.3% good understanding, and 46.7% adequate understanding. Furthermore, 93.3% of students expressed positive attitudes towards physics practical activities and actively participated in recording and maintaining laboratory equipment. The programme also supported the development of students’ soft skills, particularly communication, collaboration, and leadership. Overall, the programme demonstrated the potential of university–school collaboration to strengthen laboratory management, enhance physics learning experiences, and provide a sustainable partnership model supporting the implementation of the Merdeka Belajar-Kampus Merdeka (MBKM) policy.
