Abstract
Reading ability is a fundamental component of elementary education; however, the availability of literacy facilities does not necessarily ensure their optimal use. This community service program aimed to optimize school assets through the Jendela Baca Program with TATAKAN (Library Organization) and to examine changes in students’ interest and participation in reading activities. The program employed the Asset-Based Community Development (ABCD) approach through the stages of Discovery, Dream, Design, Define, and Destiny. The activities involved seven students and one teacher at SDN Sempu, Ponorogo Regency. Data were collected through observation, interviews, and documentation and analyzed descriptively using qualitative analysis and technique triangulation. The results showed that mobilizing existing assets, including the library, book collections, teachers, students, and established reading habits, transformed the library into a more organized, comfortable, attractive, and accessible literacy space. Following the program, students demonstrated greater interest in selecting and reading books, increased participation in literacy activities, and improved reading confidence among several participants. These findings indicate that optimizing internal school assets through the ABCD approach can serve as a contextual strategy for strengthening the literacy environment. Program sustainability requires regular reading habits, continued teacher assistance, and consistent participation of the school community in maintaining and utilizing the library.
