Abstract

The fruit of the berry (Crescentia cujete) had been widely known by the community. However, the use of this fruit had not been widely explored, especially related to the morphology and anatomy of the fruit, which supported its potential as a sustainable basic material. This study aimed to study the morphology and anatomy of berenuk fruit and explore its use as a basic material for crafts and household tools. The method used was qualitative descriptive, and the sampling technique was purposive sampling. Data was collected through field surveys, interviews with local artisans, and direct observation of the processing and utilization process of berenuk fruits. The data was reinforced through literature studies. The results of the study showed that Berenuk Fruit had great potential in diversifying the local economy, creating business opportunities, and supporting environmental conservation. The morphology and anatomy of the berenuk fruit, such as its hard skin and wide inner cavity, strongly supported the use of this fruit as a raw material for crafts and household tools. Furthermore, it was very necessary to increase people's knowledge and skills regarding processing techniques to maximize the use of berenuk fruit, as well as a good marketing strategy so that this fruit-based product could compete in a wider market.

Abstract

This study set out to investigate the application of the ethnoscience-focused PjBL-STEM model in biology education.  By examining traditional meals as part of local wisdom, this methodology focuses on ethnoscientific values.  A descriptive qualitative method incorporating literature review approaches was employed to investigate the idea, application, and future possibilities of this model.  The study's findings suggest that PjBL, STEM, and ethnoscience can be combined to enhance the relevance, context, and cultural richness of education.  Additionally, it has been demonstrated that this model fosters the growth of 21st-century abilities including critical thinking, creativity, communication, and teamwork as well as greater scientific literacy and learning motivation. Teachers serve as a link between local knowledge and contemporary science. Therefore, theethnoscience-oriented PjBL-STEM model can be an effective approach in realizing contextual, applied, and culturally rooted biology education.
