520 _aIn the Philippines, coffee is consumed by many because of its economic impact and cultural significance. The moisture content of coffee determines its quality because less than or too much can cause it to deteriorate. Some drying techniques are destructive, time-consuming, and expensive so moisture measurement of green coffee beans with an accurate, cost- effective, and rapid approach remains a dilemma. Hence, this study developed a capacitance-based method of a drying and storage with controlled temperature and humidity system which will adapt the Scrum Methodology. The researchers assessed the effectiveness of the system in terms of accuracy, efficiency, and timeliness; and evaluated it using ISO 25010:2023. Calibration and paired sample t-test was done to determine the capacitive moisture sensor’s accuracy. Results showed that there’s no significant difference between the moisture content readings of the system’s capacitive moisture sensor and the industry moisture meter (p-value = 0.63 ≥ 0.05). With a strong correlation of 0.98, a small mean difference of 0.07, and a close variance; this confirms its consistency and reliability. Furthermore, the initial moisture content and drying time are both factors in the 0.47 or 47% variability in the final moisture content for 20 trials done by the researchers. The timeliness of the system also showed that ideal GCB only takes up 91 seconds to complete, while under-dried GCB takes 141 seconds, and highly under-dried takes the longest time for 156 seconds. The evaluation results also indicated that the system is “Very Good” with an average evaluation grade of x̄= 4.42. Finally, the topic pertains to UN-SDG 9, 2, and 3, Agriculture, Aquatic and Natural Resources (HNRDA-AANR) and Climate Change Adaptation and Mitigation and Disaster Risk Reduction under Section 3 of the DOST Agenda, and the TUP R&D agenda “Transforming the future through emerging technologies and engineering for IoT” and “Universal solutions for food security and health”
