Application of Integrated Research Methods in the Production of Dried Bananas
Main Article Content
Abstract
This study aimed to: 1) identify the challenges associated with dried banana production in Phetchabun Province using qualitative research methods, and 2) explore solutions to these production challenges through quantitative research methods. A mixed-methods approach was employed to comprehensively analyze the environmental factors affecting dried banana production. Qualitative data was collected through in-depth interviews and non-participant observations, with a sample selected via snowball sampling.The primary issue identified in the qualitative study was the high humidity in Phetchabun, which led to mold growth and spoilage during banana drying. In the quantitative phase, a completely randomized design (CRD) was used to determine the optimal temperature for drying bananas. The study examined three temperature ranges 48-52 °C, 58-62 °C, and 68-72 °C over a 12 hour drying period, with five replications for each condition. The results indicated that the optimal drying temperature for dried bananas was 58-62 °C, which effectively reduced humidity levels to 21%, minimizing spoilage and mold growth.Additionally, the study tested the effects of relative humidity on dried banana production, with experiments conducted at three levels: 50%, 60%, and 70%. The results revealed that the optimal relative humidity for banana drying was 50%, as it was the lowest level that significantly reduced the risk of mold growth and spoilage.The findings of this study highlight the effectiveness of combining qualitative analysis with quantitative experimentation. By identifying the key environmental challenges and testing potential solutions, this research provides actionable insights that can help improve the efficiency and quality of dried banana production in Phetchabun Province.
