Abstract

Kegiatan pengabdian ini dilatarbelakangi oleh kebutuhan untuk meningkatkan literasi teknologi dan mengembangkan keterampilan abad ke-21 pada siswa Sekolah Dasar yang memiliki akses terbatas terhadap teknologi. Tujuan dari kegiatan ini adalah mengenalkan dan melatih robotika sebagai sarana menumbuhkembangkan bakat dan minat siswa di bidang teknologi khususnya robotika, serta mengurangi ketergantungan pada gawai. Mitra sasaran adalah siswa SD di Desa Tlagah Kabupten Sampang, dengan jumlah peserta sebanyak 40 Siswa dan 8 Guru. Metode pelaksanaan menggunakan pendekatan yang diadaptasi dari Vincent II, J.W. Evaluasi kegiatan menggunakan pre-test dan post-test, observasi dan wawancara. Hasil pre-test menunjukkan pemahaman awal siswa yang terbatas tentang robotika. Setelah pelatihan, rata-rata skor post-test meningkat signifikan dari 35 menjadi 82 menunjukkan peningkatan pemahaman konsep robotika. Observasi mencatat partisipasi aktif dan kreativitas siswa dalam merancang robot. Wawancara menunjukkan respon positif dari siswa dan guru terhadap peningkatan minat dan kreativitas siswa. Kegiatan ini menunjukkan bahwa pelatihan robotika efektif dalam menumbuhkembangkan bakat dan minat siswa, serta berpotensi besar untuk dikembangkan lebih lanjut sebagai upaya membangun generasi muda yang siap menghadapi tantangan era digital.

Abstract

Melon cultivation requires appropriate light intensity and photoperiod management because light directly affects photosynthesis, vegetative growth, and plant productivity. In conventional cultivation, additional lighting is often controlled manually, making it less adaptive to changes in sunlight intensity, temperature, and daily photoperiod. This study develops an Internet of Things (IoT)-based automatic light intensity control system using the Fuzzy Sugeno method to optimize photoperiodism in melon plants during the vegetative phase. The system integrates an ESP32 microcontroller, BH1750 light intensity sensor, DHT21 temperature sensor, real-time clock, AC light dimmer, LED grow light, LCD I2C, and Blynk application. The Fuzzy Sugeno method was implemented to determine the percentage of LED grow light output based on light intensity, temperature, and daily time period. Experimental results showed that the BH1750 sensor calibration reduced the average measurement error from 10.13% to 2.753%, while the DHT21 temperature sensor calibration reduced the average error from 3.95% to 0.31%. The AC light dimmer responded proportionally to PWM input, producing lamp outputs from 0 lux to approximately 28,000 lux. Data transmission to Blynk was successful with an average delay of about 1.01 seconds. Plant testing for 14 days showed that the IoT-based automatic lighting system produced better vegetative growth than the conventional method, with plant height reaching 19 cm and five leaves. These findings indicate that the developed system can support adaptive lighting control for melon photoperiodism optimization.
