However, it is unfortunate that there is still a lack of utilization of porang tubers flour as a food source. Therefore, the author made a kastangel cake with the addition of porang tuber flour to further develop the use of porang bulbs flour as a cake base and to find out the interest of the surrounding community towards the preference for products made with porang tuber ingredients. This study uses a questionnaire method with a preference test from the panelists, then the authors look for information on a good formulation to be applied to the kastangel cake before being tested on the panelists. Which later the author will record the answers of respondents from the results of the questionnaire.
