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

This systematic review maps how innovation, technology adoption, and Islamic entrepreneurial behaviors are intertwined and contribute to the SDGs. Searches in Scopus followed PRISMA 2020: of the 166 initial records, 46 were eliminated prior to screening; 120 filtered by title–abstract; 45 read in full; and 25 articles were analyzed in depth. Four RQs lead the synthesis: the form of innovation/adoption (RQ1), impact on behavior and performance (RQ2), and their relationship to the SDGs (RQ3). The findings show five complementary faces of innovation: (1) process-organization (knowledge management, open innovation; innovation capability), (2) sharia business/finance models (sharia venture capital, agricultural value chain finance), (3) financial and platform digitalization (fintech, Islamic crowdfunding), (4) technological innovation in business models (e.g., urban farming–aquaponics) that are value-framed, and (5) halal product/marketing innovation (halal assurance and halal trust). Behind that, the drivers are layered: individual values and psychology, Islamic HRM cultural orientation and organizational learning, Islamic finance architecture and regulation, and access to digital literacy and trust in the platform. The impact is multidimensional performance, access to ethical capital, halal market behavior, and social and religious environmental outcomes with strong contributions to SDG 8 and SDG 9, and footprints on SDGs 1–2, 3, 10, 11, 12, 13, 16, 17. This SLR offers an integrated financial innovation value framework and proposes SDGs micro-indicators; limitations mainly in the variation of measurements and the dominance of cross-section designs.
