Kinerja Automatic Ring Irrigation With Solar Panel Energy (Arisgy) dengan Perbedaan Diameter Lubang Irigasi Cincin terhadap Pertumbuhan Tanaman Selada (Lactuca Sativa L.)

Abstract

Ring irrigation system is an irrigation system that seeps water in plants with a small discharge in the root area of plants and maintains soil moisture with a ring-shaped medium as an emitter. This study aimed to analyze the effect of ring hole diameter variations on the growth of lettuce (Lactuca sativa L.) using solar ring irrigation (ARISGY). This study consisted of 6 plants using 3 types of treatment with different ring hole diameter sizes, namely 2 mm, 3.5 mm and 5 mm.. The research parameters observed were environmental parameters such as air temperature and humidity, water discharge, irrigation efficiency, plant growth. Results showed that the variation of ring hole diameter had a very significant effect on plant height, number of leaves, and plant productivity. Based on the highest water use efficiency in the P3 treatment, the highest water storage efficiency in the P3 treatment and the highest emission uniform efficiency in the P1 treatment.
