Evaluation of a Modified Fly Grill for Fly-Density Surveillance Practicum

Abstract

Conventional Fly Grills are simple and useful tools for fly-density surveillance; however, their size, weight, and storage requirements may limit repeated use during field practicum. A foldable and rollable Fly Grill model was developed to improve portability while maintaining its core measurement function. This study aimed to evaluate student acceptance of the modified Fly Grill as a practical learning tool. A descriptive evaluative cross-sectional survey was conducted among fourth-semester students of the Department of Environmental Health, Poltekkes Kemenkes Banjarmasin, following direct use of six modified Fly Grill units during practicum. Ninety-five valid respondents completed a 33-item, four-point Likert-scale questionnaire covering ease of use, portability, comfort, and general perception. Data were analyzed descriptively using frequencies, means, and standard deviations. The modified Fly Grill received highly favorable ratings across all domains, with mean scores of 3.72±0.40 for ease of use, 3.68±0.42 for general perception, 3.65±0.45 for portability, and 3.64±0.45 for comfort. The highest item-level scores were observed for ease of understanding the instructions and relocating the device (both 3.77±0.45), followed by ease of setup (3.75±0.44). Lower ratings were found for device weight (3.61±0.49), handle/structural comfort and stability (both 3.62±0.51), and user safety (3.63±0.49), although all remained positive. The modified Fly Grill demonstrated high student acceptance and potential as a portable and reusable practicum tool. However, this study evaluated perceptions and acceptance only; technical performance, durability, and learning outcomes were not assessed. Further comparative studies using objective measures are recommended.
