The digital-based start-up industry in Indonesia has developed, but with a high failure rate. This research aims at elaborating the relationship between business model, entrepreneurial orientation, innovation, and sustainable performance on the digital start-up companies in Indonesia. The data were collected using offline and online surveys to 206 leaders or founders of digital start-up companies spread throughout Indonesia. Then, the data were then analysed using the structural equation model. The research results revealed that a business model had a significant role in achieving sustainable performance. A business model needs to be supported by customer participation and innovation. Innovation was more influential compared to customer participation in achieving companies’ sustainable performance. The indirect effect of customer participation and innovation on sustainable performance through the business model was greater than the direct effect not through the business model. The novelty of this research is the examination and analysis of the relationship between innovation, customer participation, business model, and sustainable performance in one model, and the use of digital start-up companies in Indonesia as the research analysis unit.

Objective - This study aims to determine the conditions relating to research culture, research self-efficacy and research productivity at private universities in Riau, Indonesia, to examine the direct and indirect influences among research culture, research self-efficacy and research productivity. Methodology/Technique - A questionnaire was used to obtain responses from lecturers at 12 private universities (with a total of 349 responses). The data collected from the sample was analysed using structural equation modelling (SEM) software as the verification method. Findings – The results show that research self-efficacy among lecturers is high. Lecturers have a high research self-efficacy in writing the introduction and method of research, and a high-enough score for a broad view of research, results and discussion, and publication. The last variable is research productivity, which was also grouped in the high-enough category. The quantity dimension has average score of 2.6 which means that it is high-enough, while the scores for the quality dimensions are also high. Research culture, which has eight dimensions, has a direct influence on both research self-efficacy and research productivity. Research self-efficacy also directly influences research productivity. Novelty - This study reveals that research self-efficacy plays an important role in mediating research culture and research productivity variables. Type of Paper - Empirical. Keywords: Research Self-Efficacy; Research Productivity; Research Culture; Higher Education. JEL Classification: M30, M31, M41.

The objective of this research is to examine the religiosity on Islamic banking product decision. A survey method was employed using a sample of 2.627 employees at different level of education, level of income, gender, age, marital status, length of service, work location (provincial based), ownership of conventional banking products as well as ownership of sharia banking products among employees of PT. Telekomunikasi Indonesia. The study also developed valid and reliable scales for religiosity and selection of sharia banking product.  The findings of the study revealed that dimensions of religiosity affected understanding of Islamic Banking Concept and also affected Bank Selection Criteria. Future research is required to investigate private employees and semi government employees, even in military institutions to find different figure of religiosity and preference of sharia banking products, by identifying the specific areas of religiosity that have particular impact in determining the sharia banking products.DOI: 10.15408/etk.v16i1.4379
