This study attempts to explore the degree of financial and social sustainability of telecenters in East Java, Indonesia, and their influencing factors. An embedded, multiple-case study approach will be applied with telecenter as the main unit of analysis and community as the embedded unit of analysis. Selection of cases will be based on a comprehensive telecenter survey and confirmation from experts in the field. Mixed methods data collection and analysis techniques will be utilized with qualitative method being the primary technique. Within-case and cross-case analyses of two sets of cases of sustainable and barely-sustaining telecenters will be conducted to derive results and confirm commonalities. Q-methodology will be applied to examine community’s subjective perception towards telecenter social sustainability. An integrated framework of the Five Pillars of Sustainable Telecenters and the Change Agent element from the Diffusion of Innovation theory will be used as the conceptual basis of investigation. The outcomes of this research are expected to bring important theoretical and methodological contributions to academics as well as recommendations to policy makers and telecenter activists.
