Abstract

This study aimed to develop a Web-Based Solar-Powered Automated Hydroponics System. Further, it aimed to evaluate its technical performance. The device used WeMos technology, gathering feedback from agriculturists and farmers. It used a solar panel with the following specifications Peak Power (Pmax): 100W, Open Circuit Voltage (Voc): 21.6V, Short Circuit Current (Isc): 6.1A, Maximum Power Voltage (Vmp): 18V, Maximum Power Current (Imp): 5.56A, and Temperature Coefficient: -0.45%/°C. Agriculturists unanimously provided a perfect mean score of 5.00 across all technical aspects, indicating complete consensus and a strong endorsement of the system's capabilities. While farmers satisfaction overall mean score is 4.60. The farmers' perceptions showed slightly more variability than the agriculturists. The combined assessment from both groups was consistent with the individual results. The system's monitoring capability received the highest combined score, while report generation and ease of use received the lowest, though all scores were positive. The study underscored the capability of its Web-Based Solar-Powered Automated Hydroponics System as a promising instrument to advance modern agricultural practices and address the challenges of food production sustainably. Based on the findings of the study and to further enhance the Web-Based Solar-Powered Automated Hydroponics System, the following recommendations for additional features may be considered Advanced-Data Analytics, Integration with IoT Sensors, Mobile Application, and Comparative Analysis.

Abstract

Organizations face critical decisions regarding work models for digital presence management (DPM) teams, where onsite and remote operations present distinct trade-offs in cost, security, collaboration, and engagement. This study developed and compared scenario-based cost-benefit models for four staffing configurations (30, 60, 90, 150 workers) across onsite and remote DPM operations. We employed a scenario-based comparative analysis using projected operational data for hardware, software, licensing, staffing, and infrastructure costs (denominated in PHP). Social media engagement projections were based on a 3.5% organic reach rate, benchmarked to the dominant Philippine platform, Instagram. Sensitivity analysis was included. Remote operations demonstrated 21–28% monthly cost savings (PHP 669,850–1,337,250 vs. PHP 850,600–1,860,600 onsite). Cost per 1,000 projected reach was lower for remote models (PHP 2.66–3.18) compared to onsite (PHP 3.37–4.43). Onsite models incurred substantial upfront infrastructure costs (PHP 532,428–2,002,256). While remote DPM offers significant cost advantages, achieving equivalent security requires investment in advanced frameworks, which may offset a portion of the savings. The decision framework must therefore prioritize organizational security requirements, governance needs, and budget constraints alongside cost efficiency.
