Abstract

Precise environmental regulation is a critical component of hydroponic systems, particularly in urban agriculture, where land availability and resources are limited. This study aimed to examine the impact of an Internet of Things (IoT)-based hydroponic system with automated control of light intensity and temperature on the growth of Lactuca sativa (lettuce). A controlled experimental design was employed, involving 30 lettuce plants divided into control and experimental groups. Both groups were cultivated using a Nutrient Film Technique (NFT) system within a mini greenhouse over three weeks. Environmental parameters were recorded at 30-minute intervals using calibrated sensors, and plant growth was assessed by measuring stem height and leaf number. The results indicated growth increases of 52.44% in stem height and 48.89% in leaf count in the experimental group, suggesting that automated regulation of light and temperature contributes to a more stable growing environment and enhanced plant development. Nevertheless, this study is limited by its relatively short observation period and restricted range of growth indicators evaluated. Further investigations with extended experimental durations and more comprehensive growth parameters are required to assess the long-term effectiveness of IoT-based hydroponic systems.

Abstract

Abstark: Keselamatan listrik rumah tangga masih menjadi perhatian penting, terutama di wilayah pesisir yang memiliki kelembaban tinggi, hunian yang cukup padat, dan akses layanan teknis yang terbatas. Kegiatan pengabdian ini dilaksanakan melalui program Electro Care C4S dengan menekankan aspek communication, collaboration, critical thinking, creativity, dan skill. Kegiatan berlangsung pada 11-14 Mei 2026 di Desa Cimpu, Kecamatan Suli, Kabupaten Luwu, dengan melibatkan 4 dosen dan 23 mahasiswa Program Studi D3 Teknik Elektronika Politeknik Dewantara. Pelaksanaan kegiatan meliputi inspeksi instalasi listrik secara door-to-door pada 44 rumah, pendataan melalui web elektronika, sosialisasi hasil inspeksi kepada 28 warga, serta servis gratis terhadap 22 unit alat rumah tangga. Hasil inspeksi memperlihatkan bahwa 91% rumah mengalami kelebihan beban, seluruh rumah belum memiliki grounding, 89% masih menggunakan kabel serabut untuk instalasi tetap, dan 93% MCB utama tidak sesuai ukuran.. Tim juga berhasil memperbaiki 18 dari 22 unit alat atau 81,8%. Kegiatan ini menunjukkan bahwa kolaborasi dosen dan mahasiswa berbasis data lapangan dapat membantu masyarakat memahami risiko listrik sekaligus memperoleh solusi teknis yang langsung dirasakan manfaatnya.
