PENGEMBANGAN SISTEM OTOMATISASI PENYIRAMAN AIR BERBASIS INTERNET OF THINGS

Abstract

ANANDITTO DAFFA WIJAYANTO. Pengembangan Sistem Otomatisasi Penyiraman Air Berbasis Internet of Things. Dibimbing oleh FALDIENA MARCELITA. Penyiraman konvensional sering kali menyebabkan pemborosan air dan tingginya biaya operasional. Untuk mengatasi hal tersebut, dikembangkan sistem penyiraman otomatis berbasis Internet of Things (IoT) yang dilengkapi sensor kelembapan tanah dan flow meter. Sistem menggunakan ESP32 dan memantau kondisi secara real-time serta mengatur penyiraman sesuai ambang kelembapan yang ditentukan. Pengujian dilakukan dengan membandingkan konsumsi air antara metode otomatis dan konvensional. Hasilnya, sistem otomatis menghemat 1.326 liter air per minggu (pengurangan 70,83%) dan berpotensi menghemat biaya Rp241.332 per tahun. Analisis Return on Investment (ROI) menunjukkan nilai 16,09% per tahun dengan payback period sekitar 6,2 tahun. Sistem ini terbukti efisien dan layak diterapkan dalam skala pertanian.

ANANDITTO DAFFA WIJAYANTO. Development of Automated Watering Systems Based on the Internet of Things and Conventional Watering Methods with Return on Investment Analysis. Supervised by FALDIENA MARCELITA. Conventional watering often leads to water waste and high operational costs. To address this, an Internet of Things (IoT)-based automated irrigation system was developed using soil moisture sensors and a flow meter. The system, built on an ESP32, monitors conditions in real time and controls watering based on defined moisture thresholds. Testing showed that the system saved 1,326 liters of water per week (70.83% reduction) and reduced costs by Rp241,332 annually. Return on Investment (ROI) analysis indicated 16.09% annually, with a payback period of around 6.2 years. The system is efficient and suitable for agricultural use..
