The researchers aimed to come up with “Extraction of Banana Stem Fiber
and Malunggay Bark into a Usable Eco-Friendly Cork Board.” Normally used to
support and to organize printed material to modify or school / work feedback. An
iterative approach to design-based research (Design Based Research, or DBR)
was utilized by the researchers. The research was conducted in 4 phases: (1)
Problem and Exploring Phase, the researchers developed a cork board using a
banana stem fiber and malunggay bark. (2) Design and Development, assess
and enhance the product's effectiveness, usability, durability, and sustainability
while promoting ecofriendly practices and prioritizing aesthetic appeal and design
quality. (3) Iteration Testing Feedback Through sensory evaluations and
feedback in the third phase, the researchers identified the need to address these
issues. (4) Synthesis for Derivation Principle Based on feedback, adjustments
were made to the procedure for processing the banana stem fiber and malunggay
bark to achieve a finer result.
