Indigenous Knowledge of “Bir Pletok” From the Betawi Tribe As Content In Making an Educational Video On the Biodiversity Topic

Indonesia is rich in biodiversity, but some studies indicate that students’ understanding of biodiversity topics remains limited. Biodiversity is closely related to the utilization of plants in indigenous knowledge, such as bir pletok from the Betawi Tribe. Therefore, this research examined the indigenous knowledge of bir pletok, including the tools and materials used and the process of making it. Additionally, this research produced educational videos as a learning medium to support students’ understanding. The method used was field exploration through interviews, direct observation, and documentation of the bir pletok-making process. Bir pletok is a traditional drink that has been passed down through generations and is prepared using traditional tools. Nine plant species are used in making bir pletok, including Ginger ( Zingiber officinale Rosc.), Lemongrass ( Cymbopogon ciratus (DC.)), Cinnamon ( Cinnamomum burmannii ), Nutmeg ( Myristica fragrans Hault.), Cardamom ( Elettaria cardamomum (L.), Pandan ( Pandanus amaryllifolius Roxb.), Sappan wood ( Caesalpinia sappan L.), Sugarcane ( Saccharum officinarum ), Cloves ( Syzygium aromaticum ). The making process involves six stages, from grinding the ingredients to serving the drink. The 11-minute 59-second educational video, published on YouTube, aims to enhance students’ understanding of biodiversity and foster an appreciation for cultural diversity and indigenous knowledge.
