Generally, this study aimed to design a Smart Hydroponic System for Oregano. It sought to develop and fabricate a smart hydroponic system. The hydroponic system allows growing oregano and monitoring the device using Internet-of-Things (IoT). The device can be monitored by the user wherever internet is available. The smart hydroponic system was assessed by 31 individuals, consisting of 25 end-users and 6 experts. It was transported, installed, and observed in Malaya, Pililla, Rizal during the academic year 2023–2024. The researchers developed a smart hydroponics system for oregano. The system uses an IoT-based monitoring system to track pH, water tank, temperature, humidity, water flow, and water level. The system is powered by 220V and 12V using a transformer. It also includes real-time data displayed through an app. The system is accessible on various devices and is used for growing oregano. In attaining the intended objectives, descriptive and developmental research methods were considered. The produced oregano by the smart hydroponic system consisted of 22 plants that comply with the conditions of the McCormick Science Institute and Atta et al. (2023). Moreover, the weighted mean was used to determine the freshness and maturity of the produced oregano. Based on the assessment, the average vibrance of the oregano produced is vibrant green, considered fresh according to McCormick Science Institute, with an average size of 4.70 inches as the ideal harvesting height, which was within the acceptable range. Harvesting the leaves and stems begins approximately 4 to 10 inches from the ground. The smart hydroponic system was evaluated through a researcher-made questionnaire based on ISO/IEC 25010 standards. In addition, weighted mean was utilized to determine the level of acceptability of the smart hydroponic system in terms of functional suitability, reliability, safety, usability, and maintainability. Based on the results of the evaluation, the smart hydroponic system was highly acceptable, with an overall average of 3.68 by the respondents across all criteria. The researchers have developed a user manual, which includes information to guide and inform end-users about safety precautions, operation, and maintenance of the developed device. The researchers concluded that the smart hydroponic system can be used to produce quality oregano within 21 days of the growing process from seedlings. It was designed with a real-time monitoring system. The system met ISO/IEC 25010 standards and was highly acceptable to respondents. The user manual provided comprehensive information on location selection, safety precautions, operating instructions, and maintenance guidelines, ensuring safe and efficient operation of the hydroponic unit. Lastly, the researchers recommend further studies to attain more effective growing of oregano in the smart hydroponic system. Another recommendation is for future researchers to determine the advantages of its application in a larger field. Integrating temperature and humidity control into the system would be beneficial for raising diverse plant species and accurately reproducing their natural habitats.
