Abstract

The creation of questionnaire forms based on research papers has been done for various purposes. In previous studies, the surveyor intentionally created questions to be used in questionnaires based on secondary research and the knowledge of the researcher, and it is unclear what procedure was used to create the questions. Therefore, in this study, we examined and discussed methods of mechanically creating questions based on a review of research papers. As a result, we proposed a new method to create questions by mechanically combining words obtained from the article search, text mining of extracted articles, and co-occurrence word search.

Abstract

Quality improvement is important to reach customer satisfaction and gain the competitive advantage. This research was using the Taguchi experiment design to obtain a combination of roasting parameters, which could in turn improve the quality of coffee powder. During the roasting process, the acids that were naturally contained in coffee beans were transformed into acetic acid, malic acid, citric acid, and phosphoric acid, which in turn contributed to the coffee’s actual taste. Several key factors contributed to the taste of coffee powders, namely roasting temperature, roasting time, the weight per roasting, and cooling time. The significance factor to improve quality of Robusta coffee powder namely roasting temperature on 185 °C, roasting time in 20 minutes, weight per roasting is 7.5 kilograms and cooling time is 10 minutes. The organoleptic tests of the resulting coffee powders showed an average of 4.93 with regards to consumer rating. The experiment result revealed the optimal setting level that should be applied in the production process of coffee powders for gaining better quality and thus more favourable to consumers.
