This study aimed to develop glue for art and craft using lignin extracted from coconut husks. The waste coconut husks were collected from wet and dry markets in Masambong, Quezon City, Bacoor, Cavite, and Sta. Ana, Manila. The production process involved lignin extraction from the coconut husks, followed by pounding, pulverizing, boiling, and the addition of additives to create the final product. The viscosity and adhesiveness of the glue were tested at the Adamson University Technology Research and Development Center (AUTRDC) to determine the key parameters. The viscosity was measured using the Engler method, resulting in a viscosity of 11,087 cPs, higher than that of water. To assess adhesiveness, manual application methods were employed at the AUTRDC, where paper was bound and scraped to test the strength of attachment. The results showed that the adhesiveness remained intact even under applied force, indicating its effectiveness. The acceptability of the glue was evaluated by 30 respondents using an evaluation instrument. The criteria included Durability, which received the highest rating of 4.81. Saleability received a rating of 4.76, and Workability received a mean score of 4.75. Safety had the lowest rating of 4.48 but was still considered "Highly Acceptable." The glue also scored well in Economy (4.70) and Functionality (4.69). The overall mean rating for this project was 4.69 out of 5.00, indicating a high level of acceptability. Based on the evaluations, it can be concluded that the glue produced from coconut husk lignin has the potential to be used as an adhesive for arts and crafts.
