Value Added in Agarwood Oleoresin Extraction: Benefits of Microwave and Ultrasonic Maceration

Background: Agarwood farmers are currently unable to extract agarwood oil because they do not get any benefit from the processing process due to the high cost and the yield obtained is still low; it is necessary to identify the right processing method so that they can obtain high agarwood oil and the cost is not too expensive. The added value of agarwood oil can be obtained by processing agarwood into oleoresin through agarwood oil extraction. Methods: This study consists of several aspects of identifying the added value of agarwood oil. The first aims to extract agarwood oil using several techniques, namely microwave-assisted extraction (MAE) and ultrasonic-assisted extraction (UAE). Then calculate the Life Cycle Costing (LCC) and the added value of agarwood oil using the Hayami method. Result: The calculation of life cycle costing shows that microwave-assisted maceration is the most effective and cheapest extraction method, with a cost of IDR 1,063 and has an extract yield of 4 grams during the 24-hour extraction process. An extract yield of 2 grams was obtained for 24 hours for IDR 2,127 for the extraction process using the ultrasonic-assisted maceration method. The results of the calculation of added value from the comparison of agarwood oil extraction methods show that the agarwood oil processing method with the microwave-assisted maceration method obtains higher added value compared to the ultrasonic-assisted maceration method, which is IDR 7,875,496 / kg. and obtains a profit of IDR 6,675,496 / kg. Therefore, the microwave-assisted extraction method can be used to increase agarwood oil production.
