Abstract

The advancement of technology has driven the implementation of automation systems across various sectors, including agriculture. One such innovation is the automatic irrigation system that autonomously regulates water needs based on the surrounding environmental conditions. This study aims to design and implement an prototype automatic irrigation system based on fuzzy logic using the ESP32 microcontroller, which is capable of efficiently and adaptively managing plant irrigation. The system is designed using three sensors as the main input parameters, namely the HD-38 sensor for soil moisture, the PH-4502C sensor for water pH, and the HC-SR04 sensor for water level in the reservoir. These sensors are connected to the ESP32 microcontroller and controlled using the Mamdani fuzzy logic method to determine the operation of the filling and sprinkler pumps. The fuzzy categories used in the system include: soil moisture (dry, moist, wet), water pH (acidic, neutral, alkaline), and water level (empty, medium, full). The outputs are the automatic on/off status of the pumps based on the combination of the input conditions. The test results of this prototype show that the system operates optimally. The soil moisture sensor achieved an average accuracy of 93.17%, the water level sensor 96.67%, and the pH sensor 96.11%. These results demonstrate that the fuzzy logicbased automatic irrigation system is effective in controlling water distribution and can help improve water usage efficiency in agricultural land.

Salah satu inovasi yang dikembangkan adalah sistem irigasi otomatis yang dapat mengatur kebutuhan air secara mandiri berdasarkan kondisi lingkungan di sekitar lahan. Penelitian ini bertujuan untuk merancang dan mengimplementasikan prototipe dengan sistem irigasi otomatis berbasis logika fuzzy menggunakan mikrokontroler ESP32 yang mampu mengatur pengairan tanaman secara efisien dan adaptif. Sistem dirancang dengan menggunakan tiga sensor sebagai parameter utama input, yaitu sensor HD-38 untuk kelembaban tanah, sensor Ph-4502C untuk pH air, dan sensor HC-SR04 untuk level air pada tandon. Ketiga sensor ini terhubung ke mikrokontroler ESP32 dan dikendalikan menggunakan metode logika fuzzy Mamdani untuk menentukan pengoperasian pompa pengisi dan pompa sprinkler. Kategori fuzzy yang digunakan dalam sistem meliputi: kelembaban tanah (kering, lembab, basah), pH air (asam, normal, basa), dan level air (kosong, sedang, penuh). Output berupa status aktif atau tidaknya pompa dikendalikan secara otomatis berdasarkan kombinasi kondisi masukan tersebut. Hasil pengujian dari prototipe ini menunjukkan bahwa sistem dapat berjalan secara optimal. Sensor kelembaban tanah memiliki akurasi rata-rata sebesar 93,17%, sensor level air sebesar 96,67%, dan sensor pH air sebesar 96,11%. Hasil ini menunjukkan bahwa sistem irigasi otomatis berbasis fuzzy logic ini mampu bekerja secara efektif dalam mengontrol distribusi air, serta dapat membantu meningkatkan efisiensi penggunaan air pada lahan pertanian.
