AC 220V DIGITAL THERMOSTAT BASED DRYING OVEN XH-W3001 TO IMPROVE TEMPERATURE ACCURACY IN THE DRYING PROCESS OF BLACK BETEL LEAVES (PIPER BETLE VAR NIGRA) AT PT. FBION KARANGANYAR

Abstract

The purpose of this study was to find out how to manufacture and test results of a black betel leaf dryer (Piper Betle Var Nigra) based on Digital Thermostat AC 220V XH-W3001. The research method used in data collection for this tool is the experimental method. The way to make a black betel leaf dryer (Piper Betle Var Nigra) based on Digital Thermostat AC 220V XH-W3001 is by connecting a heating coil, power fan and digital thermostat. The heating coil and fan will turn on when the temperature in the oven has reached and exceeds the specified lower limit. The trial results of the black betel leaf dryer (Piper Betle Var Nigra) based on Digital Thermostat AC 220V XH-W3001 have excellent temperature accuracy in the drying process of black betel leaves as evidenced by the use of this tool in testing the device with a temperature of 40°C- 45°C.
