(Similarity + Document) Temperature and Time Optimization of Dragon Fruit Peel Powder Drying Using the Response Surface Methodology

The purpose of this study is to obtain the right temperature and time for the
manufacture of dragon fruit peel powder and to obtain the optimal total yield and water
content. The method used in the spraying process is Foam Mat Drying. The method used
for optimization is the Response Surface Method (RSM) with a factorial centralized
composite design 22. The factors used are the temperature of 60°C, 70°C, and 80°C and
the time is 5 hours, 6 hours, 7 hours. The results showed that the composition of the
formula was the best at a temperature of 79,214°C and a time of 5,007 hours. It can be
predicted that the optimal formula gets a yield value of 16.109%, and a moisture content
of 4.662%. The total powder obtained in 1 day of production is 5000 grams, if the
production for 1 week is 35,000 grams, then 150,000 grams will be obtained for 1 month
of production. It was concluded that the optimal formula that has been obtained can be
used as a model for making powder from dragon fruit peel.
