Abstract

Cinnamon oil is usually obtained by conventional methods and takes a long time. One of the newer methods that can be used is microwave hydrodistillation. The advantage of microwaves is their ability to provide energy directly to all ingredients, which saves time compared to conventional methods. This study aims to study the effect of time and microwave power on the yield of essential oils obtained. The solvent used was aquadest, the variables tested in the study were the raw material for leaves and cinnamon bark weighing 150 grams and 100 grams, respectively. The microwave power used is 180, 360, 450 Watt. The operating conditions in this method are at atmospheric pressure. When using 180W power, the yield of leaf oil and cinnamon bark is 0.65% and 0.51%, at 360W power is 0.96% and 0.75%, and 450W power is 0.88% and 0.89%. %. The value of specific energy consumption (SEC) at 180W microwave power is 1.78 kWh / gr and 3.40 kWh / gr, at 360W power is 1.50 kWh / gr and 2.91 kWh / gr and 450W power is 1.80 kWh / gr and 2.72 kWh / gr.

Abstract

Energy requirements for production efficiency can be obtained from fossil fuels or renewable energy sources. The traditional drying process in Tekwan production is often inefficient and weather-dependent. Solar-powered drying technology using photovoltaic panels can improve cleanliness, efficiency, and product quality, and is suitable for application in Indonesia. Traditional drying faces challenges in terms of time efficiency and product quality due to weather dependence. This study designed a drying device with tiered racks and an automatic motor for heat distribution. Tests were conducted at 40°C for 1 to 5 hours to analyze moisture content, energy efficiency, and exergy. Results showed a decrease in moisture content from 57.21% to 34% after 5 hours, although it did not meet the SNI 11 standard. The highest thermal efficiency was achieved at 4 hours (84.42%), exergy efficiency was 77.61%, and the lowest exergy loss was 0.520 kJ/mol. Environmental factors, such as humidity and airflow speed, influence performance. Heat loss through convection and radiation remain the main challenges. Design improvements are needed to reduce heat loss and achieve optimal drying.
