Abstract

Abstract. The rapid advancement of digital technology in the era of the Industrial Revolution 4.0 and Society 5.0 requires university students to possess 21st-century skills, including critical thinking, creativity, collaboration, and communication. However, observations conducted among students in higher education institutions indicated that many students still lack adequate understanding and practical experience related to microcontroller and Internet of Things (IoT) technologies. This community service program aimed to enhance students’ technological literacy through hands-on microcontroller and IoT training using Arduino and ESP32 platforms with a Project-Based Learning (PjBL) approach. The implementation stages included socialization, training, technology application, mentoring, and evaluation. The results demonstrated significant improvement in students’ understanding of microcontroller and IoT concepts, enhanced practical skills, and the successful development of simple IoT-based projects such as smart lamps and temperature monitoring systems. Furthermore, the program supported the development of 21st-century competencies through collaborative activities and project presentations. This initiative positively contributed to improving technology-based learning quality in higher education and is expected to be sustainable through the provision of modules, instructional media, and continuous mentoring. Keywords: Microcontroller, Internet of Things, ESP32, Project-Based Learning, 21st-Century Skills.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan efisiensi dan kapasitas produksi pascapanen jagung pada Kelompok Tani Jiwa Baru Borong Kanang, Desa Bontolangkasa Selatan, Kecamatan Bontonompo, Kabupaten Gowa. Mitra merupakan kelompok tani produktif yang berperan penting dalam penyediaan hasil pertanian berbasis jagung di wilayah tersebut. Permasalahan utama mitra adalah rendahnya efisiensi proses pengolahan pascapanen, terutama pada tahap pemipilan, penggilingan dan penepungan jagung yang masih dilakukan secara manual sehingga memerlukan waktu lama dan tenaga kerja yang besar. Kondisi tersebut berdampak pada rendahnya nilai ekonomi produk dan keterbatasan kapasitas produksi untuk memenuhi permintaan pasar lokal. Solusi yang ditawarkan adalah penerapan teknologi tepat guna berupa alat pemipil, penggiling dan penepunga jagung berbahan bakar gas LPG yang ramah lingkungan, disertai pelatihan teknis operasional dan perawatan alat kepada anggota kelompok. Metode pelaksanaan kegiatan meliputi observasi kebutuhan mitra, perancangan dan uji coba alat, pelatihan penggunaan dan perawatan, serta pendampingan operasional secara intensif hingga mitra mampu mengoperasikan alat secara mandiri. Hasil kegiatan menunjukkan peningkatan efisiensi waktu kerja hingga 60%, peningkatan kapasitas produksi sebesar dua kali lipat dibandingkan metode manual, serta peningkatan keterampilan teknis anggota kelompok dalam mengelola alat dan hasil produksi. Selain itu, kegiatan ini juga mendorong terbentuknya sistem produksi berkelanjutan yang mendukung pengembangan usaha tani berbasis inovasi teknologi. Program ini membuktikan bahwa penerapan teknologi tepat guna yang disertai pelatihan partisipatif dan pendampingan berkelanjutan mampu meningkatkan nilai tambah, daya saing produk jagung, serta kemandirian kelompok tani di tingkat akar rumput. Kata Kunci: Teknologi tepat guna, pengolahan jagung, efisiensi produksi, kelompok tani, pemberdayaan masyarakat

Abstract

The rapid advancement of Internet of Things (IoT) technology has significantly influenced engineering and computer technology education, particularly in laboratory-based practical learning. However, many higher education institutions still face limitations in providing integrated IoT laboratory facilities, causing learning to rely on simulations or fragmented hardware modules that do not adequately represent real-world IoT system integration. This study aims to develop and validate a web server-based IoT trainer to support practical learning in higher education. The research employed a Research and Development (R&D) approach consisting of six stages: needs analysis, prototype design, product development, expert validation and limited trials, product revision, and dissemination. The developed trainer integrates an ESP32 microcontroller with multiple sensors and actuators, enabling real-time monitoring and control through an embedded web server. Data were collected through functional testing, system performance testing, and expert validation involving six experts in media, content, and instructional design. Data analysis used descriptive statistics and percentage-based feasibility calculations. The results indicate that all hardware components operated with error rates below 5% and response times under 250 ms. The web server system achieved an average response time of 648.1 ms with an error rate of 0%, indicating high reliability. Expert validation showed very high feasibility across all aspects, including programming (99.2%), content relevance (98.8%), and instructional design (100%). These findings demonstrate that the developed IoT trainer is technically reliable, pedagogically appropriate, and suitable for supporting IoT practical learning in higher education.
