    Acceptability assessment of a locally developed onion harvester hand tractor in La Union, Philippines
    (E3S Web of Conferences, 2023) Abad, Rosalinda L.; Buccat, Hipolito C.; Tam-awen, Zion Jemillinium S.; Pagaduan, Jessica A.
    Onion farmers’ attitude toward a locally developed onion harvester in the Philippines has been unstudied due to the unavailability of the machine. Based on a respondent of 26 onion farmers, an acceptability assessment of the onion harvester was implemented. Data were gathered using questionnaires at two activities of actual hands-on operation and lectures and analyzed using fisher’s exact test. The ease of operation, cleaning and maintenance, safety of operation, ease of transport, technical field performance, adaptability, and investment viability were relevant attributes used in the acceptability of the onion harvester. The majority of the respondents positively accept the onion harvester. The user operation, cleaning and maintenance, ease of transport, adaptability, and investment viability are correlated positively to the willingness to buy or rent the machine. Conversely, user safety, technical performance, and aesthetics are not correlated with adoption. Since 38.5% of the farmers have no hand tractor, the preferred acquisition is renting the onion harvester.

    Design and evaluation of locally- designed peanut digger
    (INMA Bucharest, 2024) Abad, Rosalinda L.; Jacla, Frank Michael L.; Buccat, Hipolito C.; Gañola, Paul James C.; Sapitula, Alliver P.
    Manual peanut digging in the Philippines is still a practice due to the unavailability of low-cost mechanical diggers adaptable to local field conditions. Hence, the peanut digger design and evaluation were developed. The design involves benchmarking local field practices, ANSYS analysis of the digger blade, and CAD drawing. It is designed to dig, lift, convey, and drop the peanut stalk in a windrow. Its main parts are the main frame, digger blade, belt stalk conveyor, power transmission system, and hitching system. The pulling force and power requirement for the peanut digger is 1, 387.48 N and 2.0 hp, respectively. The performance measures are the belt stalk conveyor speed levels at 205 rpm, 410 rpm, and 615 rpm, replicated three (3) times with three (3) plots per replication. They revealed an actual field capacity, digging efficiency, and mechanical physical damage of 0.025 ha/h, 95.31%, and 0.56%, respectively. Investing in the machine is economically viable with a benefit-cost ratio (BCR) of 2.09, a break-even point (BEP) of 5.33 ha/yr, and a payback period of 1.60 years. This implies that digging operations wider than 5.33 ha/yr start profit generation for farmers. © (2024), (INMA Bucharest). All rights reserved.
