Abstract

In this study, a tool was developed to determine the
roasting level of beans. With current technological developments, it
is possible for us to determine the roasting time and roasting level
and to see the temperature in a roasting process with the ISL29125
color sensor and the DS18B20 temperature sensor. This study uses
the K-NN (K-Nearest Neighbor) method. So that this research can be
useful to streamline the time in roasting coffee beans. From the
experiments that have been done, it takes 1 hour 57 minutes to roast
Green Bean coffee beans to Dark Roasting level coffee beans. To
roast Green Bean coffee beans to Light Roasting level coffee beans,
it takes 43 minutes. To roast Light Roasting level coffee beans to
Medium Roasting level coffee beans it takes 36 minutes. To roast
Medium Roasting coffee beans to Dark Roasting level coffee beans
it takes 36 minutes.
