Abstract

Research aims: This study conducts a systematic literature review to explore the evolving landscape of sustainable infrastructure investment and financing by applying the PRISMA method and bibliometric analysis to 4,308 publications from 2009 to 2023. From this corpus, 74 peer-reviewed journal articles were selected for in-depth analysis based on their relevance and methodological rigor. Design/Methodology/Approach: This systematic literature review employs the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology to examine the financing and investment dimensions of sustainable infrastructure Research findings: The findings reveal that sectors such as renewable energy, green transportation, water and sanitation, healthcare, and digital infrastructure dominate discussions of sustainability due to their significant environmental and social impact. In terms of financing, traditional sources such as government budgets are being complemented by innovative mechanisms, including Public-Private Partnerships (PPPs), green bonds, ESG-linked financing, and blockchain-based tokenization. Furthermore, the study identifies a research trend toward the integration of Environmental, Social, and Governance (ESG) criteria, digital innovation, and collaborative governance as foundational elements of sustainable infrastructure development. This research contributes a conceptual framework for integrating green finance in sustainable infrastructure and highlights the interdisciplinary, technology-driven, and policy-relevant nature of this emerging domain.

Abstract

This study aims to examine the influence of Key Opinion Leaders (KOL) and consumer trust on purchasing decisions of meat products at Agro Meat Shop. This research employs a quantitative approach using a survey method. Primary data were collected through questionnaires distributed to 148 respondents who were consumers of Agro Meat Shop, supported by unstructured interviews. Secondary data were obtained through literature studies. The data analysis techniques used include validity test, reliability test, classical assumption test, multiple linear regression analysis, coefficient of determination, as well as hypothesis testing using partial test (t-test) and simultaneous test (F-test). The results show that Key Opinion Leaders (KOL) have a positive and significant effect on purchasing decisions. Similarly, consumer trust also has a positive and significant effect on purchasing decisions. Simultaneously, Key Opinion Leaders (KOL) and consumer trust have a significant effect on purchasing decisions of meat products at Agro Meat Shop. These findings indicate that the role of KOL in attracting attention and delivering information, along with consumer trust formed through experience and product perception, are important factors influencing purchasing decisions. The better the role of KOL and the higher the level of consumer trust, the greater the likelihood of consumers making purchasing decisions
