Abstract :
One of the most abundant natural resources in Indonesia that has very good prospects for development is Non-Timber Forest Products (NTFPs). The purpose of this study was to determine the retention of langge extract (Homalomena propingua ridl) on durian wood (Durio zibethinus) and to determine the effect of adding langge extract (Homalomena propingua Ridl) on durian (Durio zibethinus) to soil termites (Coptotermes curvignathus). This research was conducted from February to August 2018. This study used a non-factor randomized block design, namely the concentration of Langge extract (Homalomena propingua Ridl) valued at 0%, 5% and 10%. The results of this study indicate that the concentration of langge extract has no significant effect on the control of soil termites. The highest test weight loss at a concentration of 10% (52.52%) and the lowest at 5% (9.95%)
