Abstract
Climate change has a significant impact on citrus growth, which relies on water and nutrients for the development of stems, leaves, flowers, and fruits. To cope with climate uncertainty, citrus orchards need a good and optimal irrigation system. However, farmers in Simalungun still use conventional watering methods that are time-consuming and highly dependent on weather conditions. Meanwhile, drip irrigation is commonly used in low-pressure systems, whereas modern IoT-based irrigation is challenging to implement due to internet limitations, the lack of electricity in orchards, and high installation costs. This study aims to design an irrigation system using a photocell timer and PVC valve that operates without electricity or the internet, utilizing local components. The research method included designing a system on ±1 ha of orange land by creating a prototype for one group of plants using a 6.5 HP gasoline engine, a Tanika TWN 22 sprayer pump, a 3000- liter tank, PVC pipes, and irrigation settings controlled by a photocell timer for each group of plants. The results showed an increase in time efficiency of up to 89.12% and labor efficiency of 66.67%. This system is easy to implement, more energy and labor efficient, and saves 18.01% to 29.15% of water. The optimal operating pressure of the pump in that irrigation system is 3 bar. In conclusion, despite infrastructure limitations, the photocell timer-based irrigation and fertilization system for citrus trees offers an efficient, practical, and sustainable solution for farmers in Simalungun District, North Sumatra Keywords: Irrigation; Photocell Timer; PVC Valve Perubahan iklim mempunyai pengaruh besar terhadap pertumbuhan tanaman jeruk, yang memerlukan air dan nutrisi untuk pertumbuhan batang, daun, bunga dan buah. Untuk menghadapi ketidakpastian iklim, kebun jeruk memerlukan sistem irigasi yang baik dan optimal. Namun, petani di Simalungun masih menggunakan metode penyiraman konvensional yang memakan waktu lama dan sangat bergantung pada kondisi cuaca. Sementara itu, irigasi tetes umumnya digunakan pada sistem bertekanan rendah, sedangkan irigasi modern berbasis IoT sulit diterapkan karena keterbatasan internet, ketiadaan listrik di kebun, serta tingginya biaya instalasi. Penelitian ini bertujuan merancang sistem irigasi menggunakan timer photocell dan valve PVC yang beroperasi tanpa listrik maupun internet, dengan memanfaatkan komponen lokal. Metode penelitian mencakup perancangan sistem pada lahan jeruk ±1 ha dengan membuat prototipe satu kelompok tanaman dengan menggunakan mesin bensin 6,5 HP, pompa sprayer Tanika TWN 22, tangki 3000 liter, pipa PVC, serta pengaturan irigasi yang dikendalikan oleh timer photocell pada setiap kelompok tanaman. Hasil penelitian menunjukkan peningkatan efisiensi waktu hingga 89,12%, dan efisiensi tenaga kerja 66,67%. Sistem ini mudah diimplementasikan, lebih hemat energi dan tenaga kerja, serta menghemat air sebesar 18,01% sampai dengan 29,15%. Tekanan operasi optimal pompa pada sistem irigasi tersebut berada pada 3 bar. Kesimpulannya, di tengah keterbatasan infrastruktur, sistem irigasi dan pemupukan jeruk berbasis timer photocell menjadi solusi yang efisien, praktis, dan berkelanjutan bagi petani di Kabupaten Simalungun, Sumatera Utara.
