Abstract

Komak bean (Lablab purpureus (L.) Sweet) belongs to the family Fabaceae and subfamily Papilionidae. Komam bean is cultivated by people for consumption as an additional food source. Informationabout the active compound content of komak bean is needed as a reference in the utilization of komak. This research aims to determine the active compounds contained in komak seed (Lablab purpureus (L.) Sweet). This study used GC-MS analysis to determine the active components of the komak bean seed. Based on research result, komak Beak Bongkor bean contain 13 active components, they were toluenea, methyl octanoat, adacene 12, isododecane, caprylic acid, retardex, 1-undecene 7-methyl-, methyl caprate, capric acid, benzoic acid 4-ethyl-, palmitic aldehyde, methyl laurate dan lauric acid.

Abstract

Komak plants are local legume species (Fabaceae) widely distributed in West Lombok Regency and traditionally utilized by local communities. Ethnobotanical studies are important to document the relationship between communities, plant resources, and environmental knowledge that supports sustainable use of local biodiversity. This study aimed to analyze the morphological diversity, utilization patterns, and environmental wisdom associated with komak plants in West Lombok. Data were collected through field observations and semi-structured interviews using purposive and snowball sampling techniques across ten sub-districts. The results identified three main komak species utilized by the community, namely Lablab purpureus, Phaseolus lunatus L., and Canavalia ensiformis (L.) DC. Within the Lablab group, three variants were recorded: L. purpureus subsp. uncinatus Verdc., L. purpureus subsp. purpureus, and L. purpureus var. typicus. Community utilization of komak was classified into six categories: food, traditional medicine, traditional ceremonies, ecological functions, economic functions, and animal feed. The highest Index of Cultural Significance (ICS) was recorded for L. purpureus subsp. purpureus (59), while C. ensiformis showed the lowest value (4). In addition, komak management reflects local environmental wisdom, including mutual cooperation during harvest, traditional seed storage, and ecological adaptation practices that support the sustainability of local agroecosystems.
