STRENGTHENING GRASSROOTS INNOVATION TO PRODUCE ESSENTIAL OIL IN TANAH DATAR
Tanah Datar district has the potential for people's kaffir lime plantations of ±750 hectares located in Kanagarian Tanjung Barulak & Padang Gantiang. Currently, the community has only benefited from selling kaffir lime leaves. In addition, the community tried to process kaffir lime leaves but had not succeeded. Therefore, they asked the university for support to increase their capacity, knowledge, skills, and technology to process the leaves, fruit, and twigs of kaffir lime to produce kaffir lime oil. The strengthening of grassroots innovation is carried out in three stages, namely the introduction of Multi-Function Equipment of Essential Oil Distiller with a Combination of Ultrasonic Treatment, installation and testing of equipment on flat ground, and exploration of potential consumers for the development of essential oil products. The results obtained from the trial showed that the chopped kaffir lime leaves first gave better results than kaffir lime oil. However, further process is needed through fractional distillation to separate the components of kaffir lime oil into several compounds, such as Citronellal, Citronellol, and Linalool. The separation of kaffir lime oil needs to be done to produce various aromas that can be used in the fragrance industry. Besides that, it is necessary to make customer development efforts by building a network of various parties, starting at the local, national, and international levels, so that kaffir lime oil and its derivatives can be used as raw materials for the fragrance industry.
