Bags do not merely function as carriers for personal belongings, but also represent a lifestyle element that reflects the identity of their users. Design students have specific needs for college bags that are capable of accommodating large-sized equipment, such as A3 drawing sheets and sketchbooks. However, multifunctional college bags that adequately meet these requirements are still limited in the market. This study aims to design a two in one (2-in-1) college bag that can be used both as a shoulder bag and a backpack by utilizing local materials, namely burlap fabric, lantung tree bark, and ulap doyo patterned fabric. The design process is directed toward producing a bag that not only fulfils functional requirements but also possesses aesthetic value and represents local cultural identity. The design approach employed in this study is design thinking, which consists of the stages of empathize, define, ideate, prototype, and testing. The results indicate that the combination of these local materials is capable of producing a college bag that is comfortable to use, visually distinctive, and rich in regional cultural value. The proposed product is considered able to meet the needs of design students while simultaneously contributing to the preservation of local cultural heritage through the development of functional products based on local wisdom.
