GIS mapping and pattern distribution of smallhold pig farms in selected Barangays in the Municipality of San Joaquin, Iloilo Notada, Shane Colein S. This study was to produce a digital map of smallhold pig farms in selected barangays of San Joaquin, Iloilo through Geographic Information System (GIS) with the general objective to locate smallhold pig farms in the Brgys. of Balabago, Bulho, Dacdacanan, and Qui-anan. It also aimed to determine the annual production of pig farmers, analyze the pattern distribution in terms of different stages of pig production (breeder, grower, and finisher), and create a thematic map showcasing the location and pattern distribution of smallhold pig farms in the Municipality. San Joaquin is the southernmost Municipality of Iloilo province and has a land area of 234.84 km² with 85 barangays and purposely conducted the study in Barangays Balabago, Bulho, Dacdacanan, and Qui-anan. Smallhold pig farming is a classification of small-scale farming tending 20 sows and below or a maximum of 41 grower-finisher swine in a pig farm. The location of smallhold pig farms in four selected barangays, annual production of 1,057 heads of swine, pattern distribution with Observed Mean Distance of 492 m, 697 m, 507 m and Expected Mean Distance of 472 m, 553 m, and 482 m for breeder, grower, and finisher pig production, respectively, are concluded as random. The results of the study recommends for additional data collection of smallhold pig farms in San Joaquin, as to the suitability of the area for smallhold pig farming. As to the ongoing outbreak of African Swine Fever (ASF), GIS mapping of pig farms can be used for disease security outbreaks within a 3 km radius, thus preventing the spread of the virus to other pig farms while also reducing the implications to the economy of the Municipality.

Design, fabrication, and performance evaluation of a pedal-driven vermicompost sieve Cabarles, John Paul Eugene; Cainglet, Therese Jan S.; Estrellado, Kristine C. This study presents the design, fabrication, and performance evaluation of a pedal-driven vermicompost sieve aimed at enhancing organic waste management among smallholder farmers in the Philippines. With growing organic waste and the need for sustainable solutions, the proposed machine offers an affordable, eco-friendly option powered by human mechanics, without electricity. It is composed of the following main parts: a) single speed bike set, b) frame, c) trommel screen, d) input hopper, e) discharge chute, and f) collector. This study was completed within 5 months which covered the conceptualization, designing, pretesting and modifications of the fabricated machine until subjected to actual performance evaluation. The machine has an overall dimension of 1180 mm L x 700 mm W x 750 mm H. Performance evaluation revealed an average input capacity of 253.19 kg/hr and a sieving capacity of 137.84 kg/hr, a sieve efficiency of 55.9%, and a purity rate of 54.5% showing reliability in producing high quality vermicompost. The total investment cost for the prototype was PHP40,500.00, with an operating cost of PHP0.98 per kilogram, demonstrating an approximate return of investment after 37 days. The machine significantly improves the vermicomposting process, allowing for separation of useful compost from unwanted materials. This research not only supports sustainable agriculture but also presents a practical solution to enhance productivity and income generation in rural communities. Abtract only

GIS mapping and pattern distribution of agricultural machineries in the Municipality of Miag-ao, Iloilo

Thu, 01 May 2025 00:00:00 GMT

GIS mapping and pattern distribution of agricultural machineries in the Municipality of Miag-ao, Iloilo Faala, Joshua Van L. This study analyzed the distribution patterns of various agricultural machineries used in Miag-ao, Iloilo, such as four-wheel tractors, rice transplanters, and combine harvesters. Site visits were conducted to verify information using data sheets. GPS provided location data, and ESRI ArcGIS software was used for mapping. The analysis created thematic maps showing locations, number of units, and average horsepower of machineries used in land preparation. The data indicate that only 9 out of 119 barangays (7.56%) possess agricultural machinery. Two barangays have both a four-wheel tractor and a rice combine harvester, while two others have a four-wheel tractor and a walk-behind rice transplanter. One barangay has only a walk-behind rice transplanter. The map of agricultural machinery from this study will help the LGU, farmers, and stakeholders locate and better use machinery in the municipality. The spatial distribution using Average Nearest Neighbor Analysis revealed a random arrangement of agricultural machineries in the Municipality of Miag-ao. The pattern analysis tools generated a result indicating a p-value of 0.650209 and z-score of -0.453472; there is a less than 1% likelihood that the random pattern could result from random chance. Recommendations were provided to enhance the adoption and utilization of agricultural machinery. Overall, the integration of GIS mapping and spatial pattern analysis proved to be a powerful tool in understanding and improving the distribution and utilization of agricultural machineries in Miag-ao, Iloilo. This approach can serve as a model for other municipalities aiming to enhance their agricultural mechanization efforts. Abstract only

Design, fabrication, and evaluation of a single-shaft plastic fine shredder

Thu, 01 May 2025 00:00:00 GMT

Design, fabrication, and evaluation of a single-shaft plastic fine shredder Franco, Juan B., III; Gramo, Kay Louren C.; Porquez, Marvia June Q. This study presents the design, fabrication, and performance evaluation of a single-shaft plastic fine shredder aimed at enhancing plastic waste management efficiency. The primary objective was to assess the shredder's operational performance, including input capacity, shredding efficiency, power consumption, and operating costs. The shredder, constructed from readily available steel materials and powered by a 2 Hp capacitor electric motor, demonstrated consistent performance across trials involving PET and HDPE plastic samples. The average input capacities were found to be 0.09 kg/min for PET and 0.14 kg/min for HDPE, with shredding efficiencies of 95% and 96%, respectively, thus, exceeding the 90% efficiency benchmark set by PNS/PAES 244:2010. The study also revealed a significant reduction in volume post-shredding, averaging 91% for both materials. Electric energy consumption rates averaged at 0.52 kW-hr for PET and 0.34 kW-hr for HDPE. A thorough cost analysis indicates an operating cost of PHP11.70 for PET and PHP7.20 for HDPE per kilogram of shredded plastics and a total daily operating costs of PHP505.55 for PET and PHP483.95 for HDPE. These findings highlight the shredder's potential as an effective solution for managing plastic waste, contributing to sustainable waste management practices. This research underscores the importance of innovative machinery in addressing the growing challenges of plastic pollution. Abstract only
