Bamboo is one of the abundant natural resources in Indonesia so bamboo handicraft products are easily found in Indonesia. The most widely used technique is the plaiting technique. Many woven bamboo crafts use coiling as a framework for woven products. Coiling is a technique of rolling bamboo strips so that the resulting shape is generally rounded. Although it is often juxtaposed with the popular plaiting technique, the coiling technique is actually less glamourised and developed in Indonesia. This is because coiling has a basic circular shape and is difficult to make in small diameters, which ultimately becomes an obstacle to product development using coiling techniques. Bamboo processing also adds to the challenges for craftsmen as bamboo is susceptible to mould and bamboo-destroying organisms. Whereas the sustainable market is popular these days, especially with Gen Z. This market is a huge opportunity because Gen Z has the highest population in Indonesia today. Based on several sources, Gen Z has an interest in fashion products, one of which is jewellery. Based on this background, the design of bamboo coiling jewellery for Gen Z was carried out. The jewellery is a set consisting of earrings, necklace and bracelet. In this design, Gen Z is the target market that is the main key in jewellery styling, where Gen Z’s preferences will be the main consideration in the design process. In this design, Gen Z preferences will be explored through the main methods, namely CJM and questionnaires. Meanwhile, bamboo processing will be explored through field studies of related products and techniques as well as conducting various experiments needed such as bamboo type, bamboo preservation, coiling form, joining and coiling finishing. These methods are used to support the design process of bamboo coiling jewellery that can be customised according to Gen Z’s preferences.
