Abstract

Cassava is a tropical and subtropical plant that can be cultivated year-round in almost every region of Indonesia. Cassava can be cooked in various ways and used in a wide range of dishes. One of the signature foods of West Sumatra is “keripik sanjai” (cassava chips). Based on a survey conducted on 11 SMEs in Padang City, the types of slicers used by these SMEs are divided into two categories: tools designed to produce round cassava slices and tools designed to cut cassava lengthwise. However, the only tool available for cutting cassava lengthwise is a simple cassava slicing board. To date, there has been no alternative tool that can be used to produce longitudinal cassava slices, since when cassava is cut lengthwise using an automatic slicing machine, it tends to break apart. Despite the advantage of the simple cassava slicing board in producing longitudinal slices, SMEs still face several drawbacks when using the tool. Through this study, improvements to the design of the cassava slicing tool are proposed to enhance its usability for SMEs. This study proposes an improved design of a longitudinal cassava slicer using the Ulrich and Eppinger method. The result of this study is the development of a cassava slicing tool capable of cutting cassava in a longitudinal position without direct contact, thereby minimizing the risk of workplace accidents. The success of the tool design is evaluated based on enhanced user safety through the reduction of direct contact with the blade, as well as ease of use indicated by the stability of the tool during operation and its adaptability to various food slicing needs. The findings show that the developed tool design meets these criteria and can serve as an alternative solution for SMEs in improving efficiency. With these results, it is expected that consumer expectations can be fulfilled when using the designed cassava slicer.
