    Evaluation of tray solar dryer for cacao beans
    Reponte, Maria Fe E. (Davao del Sur State College, 2024-05)
    The evaluation of tray solar dryer for cacao beans was conducted at Davao del Sur State College (DSSC). The testing of samples was dried in the tray solar dryer in 2 batches operated separately for trials. It was revealed that the moisture content of the samples was reduced from 48% to 6.5% for the batch of operation same as the second batch reduced from 48.3% to 6.5%. It was found out that the total mean of drying rate in the second batch (2.48 g/min) was relatively high than the first batch (1.97 g/min). For the drying capacity, it was observed that the second batch (297.71 g/hr) was relatively high than the first batch (285.07 g/hr). In addition, the drying recovery revealed that the first batch (96%) was relatively high than the second batch (95%). It also observed that the drying efficiency in the first batch (4.5%) was higher than the second batch (3.7%). While the air flow rate of first batch (4.83 m3/min) was lower than second batch (5.35 m3/min). In terms of drying time, the second batch with two layers required less time (48 hours) than the first batch (60 hours). According to its financial analysis, using 4 trays had a higher return on investment of tray solay dryer for cacao beans of 80% and a payback period of 1.2 years than using 6 trays, which had 73% and 1.4 years of payback period. In conclusion, the result of the parameters in the two batches had difference from each other due to weather condition every day. It varies from time to time because of the temperature that was uncontrolled.

    GIS-based spatial mapping inventory of agricultural machineries in Bansalan, Davao del Sur
    Culango, Arah May Q. (Davao del Sur State College, 2024-06)
    Agricultural machinery has become an integral part of agricultural sector today, and has revolutionized the way of farming and production. The study conducted to assess the status of all Agricultural machineries in the area. This study was conducted at the municipality of Bansalan, Davao del Sur last November 2023 to January 2024. It aimed to assess and determine the status of all agricultural machineries in Bansalan, Davao del Sur. A complete enumeration sampling design was used in data gathering among the eleven (11) barangays with identified agricultural machineries in the municipality of Bansalan, Davao del Sur. A survey questionnaire was used to determine the owners' profile and machinery's profile using the Global Positioning System (GPS), the coordinates of the location of all machinery storage in the municipality was gathered. Results showed that 90% of the agricultural machineries were functional while only 10% were under-maintenance and non-operational. Results showed that there was 85% of registered and 15% of unregistered machineries. These results may be useful as a source of monitoring and evaluation. Moreover, registration status of the agricultural machinery need improve regulatory compliance. The inventory was utilized to monitor the usage of agricultural machinery over time, assess the impact of interventions, and evaluate the effectiveness of agricultural programs and policies. Thus, the findings may be relevant in the development of municipal legislation wherein barangay or municipal officials may use the study to propose and implement projects such as mechanization level and index mapping in specific agricultural operations in the municipality to improve the production in the municipality. Also, promote Agricultural and Fisheries Mechanization Law of 2018.
