This study examines plant water requirement management in urban farming using an automatic drip irrigation system. The system consists of 20 reused 1.5-liter bottles as water reservoirs and 20 emitters as drip control valves. The experiment was conducted on two planting beds, namely basil and mustard greens, with drip settings of 60, 125, and 180 drops. Before operation, calibration and correction factors were applied to ensure that the design discharge matched field conditions. The objective of this study was to determine the drip irrigation layout model and plant water requirements over 37 days. The layout used a parallel arrangement of three rows of plants with two rows of irrigation devices placed between them. Water demand was calculated using the radiation method based on daily evapotranspiration (ETo), considering latitude, altitude, temperature, wind speed, and relative humidity data. The results showed that ETo ranged from 8.51 to 8.84 mm/day, equivalent to 38.937 to 40.094 liters/day. After applying correction factors for each drip setting, the actual water requirement indicated surplus water stored in the soil and used for plant growth. The study concludes that drip irrigation management must account for residual soil water so that evapotranspiration demand during sunlight exposure is continuously met

Poor soil quality and inefficient nutrient utilization remain major constraints in tomato (Solanum lycopersicum L.) cultivation, often resulting in reduced plant growth, lower productivity, and suboptimal fruit quality. This study aims to evaluate the growth performance of rose tomatoes through the integration of open-field cultivation and hydroponic planting systems. The research methods included land preparation using the Pythagorean technique to ensure proper spacing and planting layout, the application of organic fertilizers to improve soil fertility, and the transition to a hydroponic drip irrigation system using rockwool as the growing medium during weeks 1 to 7 of plant development. Plant growth parameters, including plant height, leaf development, stem vigor, and overall plant health, were observed throughout the cultivation period. The results indicated that the combination of appropriate soil management practices and precise nutrient delivery in the hydroponic system significantly enhanced nutrient uptake and supported healthy plant growth. Furthermore, the drip irrigation system helped optimize water use efficiency while reducing nutrient losses. This integrated cultivation approach demonstrated its potential as an effective solution for maintaining crop quality and productivity, particularly in areas with limited land resources. Overall, the findings suggest that integrated management practices can provide a practical, efficient, and sustainable strategy for farmers seeking to improve horticultural production in modern agricultural systems.
