Abstract

Coffee is one of the most favored beverages for various age groups ranging from the young, the middle ages, to the elders. This condition is due to its delicious taste, distinctive aroma, and a million benefits of drinking it as well as being able to refresh the consumer's body. The compound that acts as a refresher contained in the coffee is caffeine. However, the excessive consumption of caffeine could bring danger to human health. So we need a method to reduce caffeine levels in the coffee bean to lower the level of caffeine. The purpose of this research is to analyze the effect of the addition of Na2CO3 on the physicochemical characteristics of coffee powder. The design used in this study is a 1 Factor Complete Random Factor. The results showed that the moisture content is ranging from 1,3768 % to 1,7287 %, and the ash content is 4,5284% to 5,1736%, and the content of caffeine is 0,9677% to 1,0187%.
