Development of Exfoliating Fiber Product Models from the Waste Material of Tamarind Processing by Using Analytic Hierarchy Process (AHP)

Abstract

The objective of this study is to develop a design of an exfoliating fiber product from tamarind processing waste by applying the Analytic Hierarchy Process (AHP) to determine the optimal design. The waste material from tamarind processing used to make the exfoliating fiber product is Srichomphu tamarind fiber. Data was collected from three experts with over five years of experience in product design and materials. Additionally, consumer satisfaction with the product's characteristics was assessed using questionnaires completed by 50 randomly selected general consumers. The results of developing the exfoliating fiber design using tamarind processing waste through the AHP under criteria for product design selection, which included functionality, size and shape, aesthetic appeal, safety of materials, environmentally friendly production methods, and affordability, indicated that the highest weighted design, with a weighted importance score of 0.568, was Design 2, the tamarind pod design. This was followed by Design 3, the dome design, with a score of 0.220, Design 1, the hand design, with a score of 0.117 and Design 4, the square design, with a score of 0.095. The overall evaluation of the product characteristics from the 50 random questionnaire responses yielded an average score of 4.38 ± 0.49, indicating a high level of satisfaction.
