Social construction of kentongan for disaster risk reduction in highland java and its potential for educational tool

Kentongan (bamboo instruments), a traditional Javanese communication tool, continues to exist to this day, and its existence is based on its function, especially in the Java mountains. Therefore, this study aimed to analyze and uncover local wisdom behind the social construction of the Kentongan, exploring the practical and symbolic meanings and the societal and cultural implications. It also explored the community's local knowledge regarding the mitigation of disasters (disaster risk reduction), as well as its cultural heritage within the community's social fabric. To unravel knowledge held by the local community, a qualitative method using a phenomenological approach was adopted, complemented by a thorough review of relevant literature. Furthermore, the snowball approach was employed to select informants, focusing on identifying key individuals who were cross-verified through member checks. The village head and the elders were identified as the key informants, and the data collected were analyzed using an interactive model. The results showed that Kentongan served as a telecommunication tool to signal disasters, alert individuals of dangerous situations, and indicate the presence of fire. Additionally, it served as a means to assemble people or initiate prayers, and the conveyed messages could be inferred through the number of beats and the sounds produced. Empathy and social solidarity emerged as the underlying social values embedded within Kentongan. The associated significance and symbolism were actively practiced and passed down through generations within the community. As a form of indigenous knowledge, Kentongan held great relevance in the lives of the local population, thereby presenting the potential to be integrated into educational contexts as a valuable source of learning.
