Abstract

ABSTRAK Sektor pertanian di Indonesia menghadapi tantangan signifikan akibat perubahan iklim dan keterbatasan akses informasi akurat mengenai kondisi tanah. Metode pemantauan tradisional yang mengandalkan observasi visual seringkali tidak efisien dan tidak akurat, berdampak negatif pada hasil panen. Penelitian ini bertujuan mengembangkan sistem informasi berbasis web yang terintegrasi Internet of Things (IoT) untuk pemantauan kondisi tanah (kelembaban dan suhu) secara real time, guna membantu petani dalam pengambilan keputusan yang lebih tepat. Sistem dikembangkan menggunakan pendekatan Research and Development (R&D) dengan metode prototipe. Tahapan penelitian meliputi identifikasi masalah, pengumpulan data (studi literatur, wawancara, observasi), perancangan sistem, pengembangan prototipe awal, uji coba, revisi, hingga produk akhir. Komponen perangkat keras mencakup mikrokontroler ESP32, sensor kelembaban kapasitif (Soil Moisture Sensor v1.2), dan sensor suhu digital DS18B20. Data sensor dikirimkan ke Firebase Realtime Database sebagai penyimpanan berbasis cloud, dengan antarmuka web dibangun menggunakan HTML, CSS, dan JavaScript. Hasil uji coba di Desa Talang Padang, OKU Selatan, selama 7 hari, menunjukkan sistem berhasil mengukur, mengirimkan, dan menampilkan data suhu serta kelembaban tanah secara real-time dan akurat. Pengujian Black Box mengonfirmasi fungsionalitas sistem sesuai spesifikasi, termasuk login, real-time monitoring dengan gauge chart dan notifikasi suara/visual, tampilan grafik garis untuk tren data historis, serta fitur riwayat data dengan opsi ekspor ke Excel/PDF. Respons positif dari petani mengindikasikan bahwa sistem ini sangat membantu dalam pengelolaan lahan pertanian, meskipun ketergantungan pada koneksi internet dan kebutuhan kalibrasi sensor lebih lanjut menjadi area pengembangan di masa depan. Kata Kunci: Sistem Informasi, Internet of Things (IoT), Pemantauan Tanah, Kelembaban Tanah, Suhu Tanah, Pertanian Presisi. iii ABSTRACT The agricultural sector in Indonesia faces significant challenges due to climate change and limited access to accurate information regarding soil conditions. Traditional monitoring methods that rely on visual observation are often inefficient and inaccurate, negatively affecting crop yields. This research aims to develop a web-based information system integrated with the Internet of Things (IoT) for real-time monitoring of soil conditions (moisture and temperature) to assist farmers in making more precise decisions. The system was developed using a Research and Development (R&D) approach with a prototype method. The research stages included problem identification, data collection (literature study, interviews, observations), system design, initial prototype development, testing, revision, and final product completion. The hardware components consisted of an ESP32 microcontroller, a capacitive soil moisture sensor (Soil Moisture Sensor v1.2), and a DS18B20 digital temperature sensor. Sensor data was transmitted to the Firebase Realtime Database as cloud-based storage, with the web interface built using HTML, CSS, and JavaScript. The trial conducted in Talang Padang Village, OKU Selatan, for 7 days showed that the system successfully measured, transmitted, and displayed soil temperature and moisture data in real-time and with accuracy. Black Box testing confirmed the system’s functionality according to specifications, including login, real-time monitoring with gauge charts and audio/visual notifications, line chart displays for historical data trends, and a data history feature with export options to Excel/PDF. Positive responses from farmers indicated that the system is highly beneficial for agricultural land management, although reliance on internet connectivity and the need for further sensor calibration remain areas for future development. Keywords: Information System, Internet of Things (IoT), Soil Monitoring, Soil Moisture, Soil Temperature, Precision Agriculture.
