Abstract

Implementasi Iot Untuk Penyiraman Otomatis Menggunakan Logika Fuzzy Mamdani Dan Pengaturan Pencahayaan Pada Tanaman Krisan (Implementation Of Iot For Automatic Irrigation Using Mamdani Fuzzy Logic And Lighting Control In Chrysanthemum Plants,) Trismayanti Dwi P, S.Kom, M.Cs, Husnul Putri Candra Buana Study Program of Informatics Engineering Majoring in Information Technology Program Studi Teknik Informatika Jurusan Teknologi Informasi ABSTRACT This research aims to design and implement an IoT-based soil monitoring and automatic irrigation system using Mamdani fuzzy logic for chrysanthemum cultivation (Chrysanthemum morifolium). The system was developed to optimize plant care through real-time monitoring of environmental parameters (soil moisture, air temperature, air humidity, and light intensity) along with automated control of irrigation and lighting. The system employs a NodeMCU ESP8266 microcontroller integrated with DHT22 (temperature & humidity), YL-69 (soil moisture), and BH1750 (light intensity) sensors. The sensor data is transmitted to Firebase Realtime Database and displayed through a mobile application built with Nylo Framework. Mamdani fuzzy logic is implemented to determine irrigation duration based on three input variables: soil moisture, air temperature, and air humidity, with the output being watering time in seconds. Test results demonstrate the system operates with 99.43% accuracy (0.57% error margin). Keywords: Mamdani fuzzy logic, automatic irrigation, IoT, NodeMCU ESP8266, DHT22, Firebase, Nylo Framework, chrysanthemum, smart greenhouse
