Dual Tank Sprayer Kit

Abstract

This study developed and evaluated a Dual Tank Sprayer Kit intended to provide small-scale pineapple farmers with a more efficient, ergonomic, and user-friendly device for applying herbicides and insecticides. Using a descriptive-developmental design, the study proceeded through planning, designing, fabrication, testing, revision, and evaluation phases. The prototype integrated a dual-tank system, automatic mixing mechanism, adjustable spray-strength control, hose and nozzle system, rechargeable battery, labeled switches, and knapsack-style support. Thirty small-scale pineapple farmers from Polomolok, South Cotabato evaluated the prototype using a validated checklist questionnaire in terms of design, ergonomics, and usability. Data were analyzed using frequency count and mode. Findings showed that the Dual Tank Sprayer Kit was highly acceptable in all three evaluation areas. The design was valued for its separate tanks, color-coded and labeled controls, and ability to reduce the need for two sprayers. Ergonomic ratings showed that the prototype was generally safe, balanced, and comfortable to carry, although improvements in weight and prolonged-use comfort were recommended. Usability results indicated that the sprayer was easy to operate, accessible, efficient, and understandable even for first-time users. The study concludes that the Dual Tank Sprayer Kit is a practical farm-tool innovation for small-scale pineapple farming, particularly for improving spraying convenience, reducing tool switching, and minimizing physical strain. Further refinement is recommended through weight reduction, protective tank housing, battery-capacity improvement, and broader field testing.
