Abstract

This systematic review investigates the influence of reading habits on the writing skills of Indonesian EFL (English as a Foreign Language) students, based on 24 selected articles from a pool of 30 Scopes-indexed studies from 2014-2024. The findings reveal a clear connection between regular reading habits and enhanced writing proficiency, particularly in grammar, creative thinking, and content organization. However, challenges such as limited exposure to English, inadequate meta-cognitive strategies, and a lack of reading culture hinder progress. Technological integration can mitigate these barriers and foster reading and writing development if effectively implemented. The study highlights strategies to promote reading habits, including using multimedia tools, encouraging independent learning, developing meta-cognitive strategies, and fostering international collaboration in academic research. By addressing these areas, educational practices in Indonesia can more effectively support EFL learners in improving their English writing skills through enhanced reading engagement.

Abstract

Despite the growing importance of startup communities in the digital economy, existing studies largely emphasize structural and policy-driven factors while underexploring the community-based mechanisms that sustain entrepreneurial growth. Addressing this gap, this study examines how startup communities strengthen the digital startup ecosystem and contribute to entrepreneurial development in Indonesia. Using a qualitative exploratory case study approach, data were collected through in-depth interviews, participant observation, and document analysis across multiple startup communities. The findings demonstrate that communities actively enhance founders’ knowledge and capabilities through structured knowledge sharing, mentoring, and skill-development programs, while simultaneously expanding social capital and network access to funding and strategic partners. Moreover, community-based incubation and collaborative support accelerate innovation and product development. This study offers novelty by conceptualizing startup communities as relational and catalytic actors that integrate key ecosystem stakeholders, including government, investors, universities, and startups. Theoretically, it advances ecosystem and entrepreneurship literature by proposing a relational framework that explains community-driven value creation within digital startup ecosystems. Practically, the findings provide actionable insights for policymakers and ecosystem managers to design community-centered strategies that improve startup sustainability and foster inclusive digital entrepreneurial growth.
