Abstract

Penelitian ini bertujuan untuk menganalisis seberapa besar pengaruh perputaran kas terhadap rasio likuiditas pada PT. Bank Negara Indonesia (Persero) Tbk Periode 2004-2018. Penelitian ini menggunakan analisis regresi linear sederhana. Analisis rasio keuangan yang digunakan terdiri dari perputaran kas, rasio likuiditas (rasio lancar) dengan teknik pegumpulan data sekunder yang diambil dari situs resmi Bursa Efek Indonesia. Hasil penelitian menunjukkan bahwa perputaran kas tidak berpengaruh terhadap rasio likuiditas dikarenakan perputaran kas yang berlebihan dengan modal kerja yang tersedia terlalu kecil, sehingga mengakibatkan kurang dapat memenuhi kebutuhan perusahaan.

Abstract

In recent decades, green bonds have emerged as a significant financial instrument in supporting sustainable finance and facilitating environmentally friendly investments. This research aims to evaluate the contribution of green bonds to the development of sustainable finance in the global capital market. Through a Systematic Literature Review (SLR) approach, we analyze various empirical studies and relevant industry reports. Findings show that green bonds not only increase access to funding for renewable energy and sustainable infrastructure projects, but also provide financial benefits through transparency and market stability. However, challenges such as greenwashing risks and lack of consistent certification standards still hinder the growth of this market. This research provides insights for investors, policy makers and academics in formulating more effective strategies to support the transition to a green economy.

Abstract

Climate change has become a significant systemic risk in the global financial landscape, yet traditional asset pricing models such as the Capital Asset Pricing Model (CAPM) and the Fama-French Three-Factor Model have not explicitly integrated this risk. A report by the BlackRock Investment Institute (2020) suggests a 5–10% valuation reduction for companies with high climate risk exposure, while the Swiss Re Institute (2021) projects an economic impact of up to 18% of global GDP by 2050. This gap highlights the urgent need to revise asset pricing models to reflect the reality of climate risk. This study aims to synthesize approaches to integrating climate risk (physical and transition) into asset pricing models, identify methodological challenges in its measurement and representation, and evaluate the validity of climate risk metrics such as ESG scores and climate beta. Using a narrative review approach, this study analyzes literature from Scopus, Web of Science, JSTOR, and ScienceDirect databases (2010–2025). The search strategy involved keywords such as “climate risk”, “asset pricing”, “ESG”, and “machine learning”. Thematic analysis was applied to identify patterns in theoretical approaches, climate variables, adopted models, and empirical results. Findings suggest that climate risk integration can be achieved through the Climate Beta concept, ESG-based models, portfolio sorting based on carbon exposure, and hybrid models with machine learning. Empirical evidence suggests that carbon-intensive sectors experience lower stock returns and increased volatility, although methodological inconsistencies remain a challenge. Integrating climate risk into traditional asset pricing models, particularly through the development of adaptive multifactor models, has the potential to improve return prediction and risk assessment. More robust methodologies, standardized environmental data, and multidisciplinary collaboration are needed to produce valid and applicable models.

Abstract

This literature review examines the role of fintech in the context of Islamic finance. Through a systematic analysis of relevant literature, this research highlights the contribution of fintech in improving Islamic financial services as well as the challenges faced in the integration process. These findings indicate that although fintech has opened the door to innovation in the Islamic finance industry, there is still a need to overcome barriers related to sharia compliance and consumer protection. Therefore, this research underlines the importance of a careful and planned approach in integrating fintech with Islamic finance principles.
