USING THE HYBRID AHP-TOPSIS TECHNIQUE FOR SELECTING PRODUCT PROCESSING AND DEVELOPMENT FOR BAMBOO PRODUCTS

Abstract

The decision-making process for selecting the processing and development of bamboo products to enhance product value is a complex problem due to the various criteria that need to be considered simultaneously. Therefore, this research proposes the hybrid AHP-TOPSIS technique for evaluating and prioritizing importance. It begins by defining relevant criteria used in decision-making, dividing them into sub-criteria, and assigning importance levels to each criterion. Then, scores are given to each criterion based on their importance levels using the AHP technique. Subsequently, the TOPSIS technique is utilized to rank and select the most efficient alternatives. By calculating the positive ideal solution (Si*) and negative ideal solution (Si'), as well as the relative closeness coefficient (Ci*), the criteria deemed important according to the needs of the decision-makers, 7 decision-making criteria, and all 5 alternative product processing methods from bamboo are assessed. The results of calculating the relative closeness coefficient (Ci*) are as follows: bamboo pressed product (A3) = 0.764, followed by bamboo reed product (A1) = 0.502, bamboo charcoal product (A5) = 0.258, bamboo skewer product (A2) = 0.167, and bamboo toothpick product (A4) = 0.154, respectively. Therefore, the method proposed in this research can serve as a guideline for selecting the processing and development of suitable products to enhance the value of other products.
