Redesign of Pineapple Peeler Using The Integration of Ergonomic Function Deployment (EFD) and Theoriya Resheniya Izobreatatelskikh Zadatch (TRIZ) Method

Abstract

The main ergonomic problem in the UMKM Berkah Sekar Abadi Women Farmers Group lies in the effectiveness of the pineapple peeler used. Physical complaints are also experienced by workers due to tool dimensions that are not in accordance with the user's posture. There are two types of peeler tools, the first tool with a fixed dimension knife, and the second tool with a knife that can be adjusted in diameter but is less effective in removing pineapple eyes. This study aims to redesign the pineapple peeler to be more ergonomic, easy to use, and able to adjust the knife diameter to the size of the fruit. Data collection was conducted through the distribution of Ergonomic Function Deployment (EFD) stage 1 and 2 questionnaires accompanied by open discussions. Analysis was conducted using the EFD method to identify user needs, as well as the TRIZ method to resolve design contradictions. From the processing results using the EFD method, 15 customer needs were obtained with an importance level value of 5 for 11 attributes and 4.5 for 4 attributes. In addition, to answer 15 customer needs, 14 technical responses were designed that can answer all customer needs. In the house of ergonomic matrix there are 9 negative correlations that occur. Then the 9 negative correlations were identified and resolved with the TRIZ method into 5 contradictions. With the TRIZ method, a design proposal was obtained by using anodized aluminum alloy material for the frame and food grade stainless steel for the peeler knife and pineapple fruit clamp, adding a protective cover, and dividing the two functions between anti-slip on the support leg and the wheels used to move the pineapple peeler.
