Abstract

Clove is one of the leading and potential commodities of the plantation in Madigondo. Currently, the community earns the economic advantage of clove plantation only from the buds. However, other parts of the clove plant have varied potential utilization. For instance, the abundant clove leaves are a valuable and potential source of essential oil. The community considered clove leaves as plantation waste due to a lack of knowledge on further clove leaves processing. The isolation of essential oil from clove leaves can be conducted by applying hydrodistillation. In this research, the hydrodistillation of clove leaves was conducted to characterize the essential oil of clove leaves as well as to investigate the production potency of clove leaves essential oil. The research was also conducted to determine the production rate and capacity of the hydrodistillation of clove leaves. The research shows that the optimum duration of the clove leaves hydrodistillation is 90 minutes. The yield of clove leaves hydrodistillation is 5.4%. The obtained essential oil of clove leaves has to have a density of 1.019 gram/mL and a typical odor of clove oil with a bright and yellow color. Those criteria meet the SNI 06-2387-2006 for oil of clove leaves.
