Kapok range is a natural fiber that has considerable potential in the form of cellulose and can be enhanced by its physical and mechanical value cellulose. This study aims to analyze the character of cellulose produced from kapok and isolation. The cellulose isolation method used a factorial complete randomized design, namely the first factor of NaOH concentration (4%, 6%, and 8%) and the second factor of extraction time (40, 50, and 60 minutes). The cellulose isolation process showed that the method did not significantly affect the yield of randu kapok cellulose. The highest yield and degree of whiteness resulted from the treatment of 4% NaOH concentration and 40 minutes of extraction time with a yield of 6.54 ± 0.82%. The following result showed that the treatment had a significant effect on the results of the degree of whiteness. The highest degree of whiteness resulted from the treatment of 8% NaOH concentration and 60 minute extraction time of 30 ± 0.7. The cellulose isolation results of kapok resulted in cellulose content of 90.15 ± 0.81%, hemicellulose content of 3.6 ± 0.52%, and lignin content of 0.91 ± 0.03%. The analyzed properties provide a strong basis for considering the potential use of such cellulose nanofibers in various industrial applications, such as the manufacture of sustainable composite materials or other valueadded products.

the purpose of this service is to provide knowledge about Product Branding and Marketing Digitalization of Tofu, Tempe Toge Products to the Gunung Kendang Community. So far, product packaging has not provided maximum hygiene and marketing, especially in the previous product packaging which still used plastic bags which were not good for health. So that assistance is needed for development in product packaging, and digitalization of marketing in an effort to increase the economy and product marketing. The methods for implementing the community partnership program service activities include; Methods of interviews, questionnaires, site condition surveys and area analysis, communication with the head of the RT Gunung Kendang and discussions with people who produce Toge, Tempe and Toge in identifying needs and supporting facilities in the production process, and determining digital marketing concepts. Through this mentoring activity produced several achievements, namely; Tofu, tempe and bean sprout business actors in Gunung Kendang Village can provide products with more attractive packaging designs, are more durable and more hygienic.
