This study evaluates the field performance of the Bantud Fabrica Solar-Powered Irrigation System in Dumangas, Iloilo, to determine the efficiency of the pump set and the PV system in wet and dry seasons. Field testing was conducted over three days for each season, following the PNS/BAFS 325. Data were measured and calculated to determine the efficiency of the project. Results indicate that during the wet season, Pump 1 exhibited an average discharge of 108.01 m³/hr with a system efficiency of11.41% and 75.94% pump set efficiency, while Pump 2 had a lower discharge of 97.15 m³/hr with a system efficiency of 7.51% and pump set efficiency of 53.87%. On the other hand, in dry season, Pump 1 exhibited an average discharge of 98.08 m³/hr with a system efficiency of 3.99% and 65.40% pump set efficiency, while Pump 2 had a lower discharge of 87.18 m³/hr with a system efficiency of 3.69% and pump set efficiency of 49.33%. Overall, the BF-SPIS led to a 13.63% increase in rice yield, highlighting its positive impact on agricultural productivity. It is recommended to improve the conveyance and resupply project for the water reservoir, divert the excess solar energy to the grid by having hybridization of the system for it to function at night, increase the capacity of the water reservoir, and improve conveyance for water delivery in the field, reinspection and modification of the solar panel set up and lastly conducting a cost-benefit analysis for the BF-SPIS economic viability and overall benefits.

In Guimaras, fishponds are essential to the local aquaculture sector, particularly in the Municipality of Jordan, the provincial capital. However, recent data highlights an erratic trend in aquaculture production over three consecutive years, with the lowest output recorded in 2020, reflecting a 10.50% decrease from the previous year. Despite advancements in remote sensing technologies like Geographic Information System (GIS), there is a notable absence of digitalized, open-access maps containing detailed fishpond information. This study aims to address this gap by integrating GIS technology and field surveys to generate a digitized map for fishponds of different classifications in the Municipality of Jordan, Guimaras. Field surveys were conducted in six of the 14 barangays, identifying eight active fishponds. Ocular visits and interviews were carried out using a profile data sheet to gather production data. Geographic coordinates were collected using the DA GeoCamera application and transferred to Google Earth Pro. These were then digitized using ArcGIS 10.8.1 software to create maps. Results showed that the majority of active fishponds are situated in Brgy. Sinapsapan (37.5%), while the other barangays contributed equally (12.5%). All fishponds were found to have concrete gates, with half utilizing a modified intensive culture system and the other half an intensive culture system. Spatial analysis using the Average Nearest Neighbor (ANN) tool quantified spatial relationships and revealed that active fishponds in Jordan, Guimaras, are randomly distributed. This study provides a valuable resource for aquaculture planning and management, promoting the sustainable development of fishpond operations in Guimaras.

The study was conducted at CPU- CARES, Research and Developmental Learning Building, Jaro, Iloilo City from April 1 to 30, 2021. This was done to evaluate the efficacy of the various preparations, concentrations, and post- exposure observation of garlic in the development of Ascaridia galli eggs. Experimental treatments were composed of different concentrations in different processing method. Goodwin’s solution and Albendazole served as negative and positive control respectively. The data were collected during the 10th, 14th and 21st day of post- exposure. The results showed that the 10th day of post- exposure time the 200 to 500 mg/ml pure juice and 400 and 500 mg/ml of aqueous extract inhibited 100% of egg development. The same trend happened to 500 mg/ml vacuum freeze- dried and 400 and 500 mg/ml dehydrated from the 14th day of post- exposure time. It was found out that various preparations at 100 mg/ml had a comparable result to positive control. Furthermore, eggs exposed to Goodwin’s solution have the lowest percentage of undeveloped eggs from the 10th to 21st day of post- exposure. Based on these results, it is concluded that garlic at different level of concentrations (100, 200, 300, 400, and 500 mg/ ml) inhibited the larval development of A. galli eggs. Garlic exhibits ovicidal effects against A. galli eggs regardless of the methods of preparation (pure juice, aqueous extract, vacuum freeze-dried, and dehydrated) and post-exposure observation.

The study was conducted to design and evaluate the performance of the seaweed chopper intended for local seaweed pre-processing. The fabrication was done at Rubit’s Machine Shop in Lapuz, Iloilo City from October to November 2016 and the performance testing and evaluation were conducted on November 28, 2016 and December 6, 2016, respectively, at the Appropriate Technology Center of the College of Agriculture, Resources and Environmental Sciences, Central Philippine University in Jaro, Iloilo City. The seaweed chopper consists of the following parts: a) main frame structure that holds the whole machine for stability, b) chopping board where seaweed materials are cut, c) guide frame that guides and secures the chopping assembly when mounted, and d) chopping assembly responsible for cutting of seaweeds. The machine chops seaweed materials into a length of 1.27 to 2.54 cm (1/2 to 1 in.). The operation of the chopper starts from the loading of seaweeds into the cutting area and are cut by the vertical shearing action of the chopping blades. The chopped seaweeds are then discharged into a container by pulling the chopping board sideward. Results revealed that the machine has an average chopping capacity of 0.60 kg/min or 36 kg/hr with an overall chopping efficiency of 97.13%, resulting in a chopped length of 2.16 cm of seaweeds. It has an investment cost of Php7,000.00. The fixed and variable costs per day amounted to Php 12.85 and Php2,576.00, respectively, giving a total cost of Php2,588.85 per day. With this, the cost incurred in operating the machine is Php 11.99 per kg of seaweed material. Abstract only 2017-04-01T00:00:00Z
