Abstract

Breast cancer shows the proliferation of malignant epithelial cells that limit the ducts and lobes of the breast. If this process is not controlled, it will cause lumps that can then spread to other parts of the body and cause death. High-mobility group box protein 1 (HMGB1) has been reported to play roles in promoting cell survival of breast cancer cells. The inhibition of HMGB1 could be a reasonable target for the treatment of breast cancer. Amaranthus tricolor has been found could reduce the viability of breast cancer cells. In this study, we aim to predict the ability of the active compounds in Amaranthus tricolor leaves to inhibit the HMGB1 through molecular docking study. The molecular docking was conducted by using the PyRx software. This study shows that the four active compounds in Amaranthus tricolor leaves, namely isorhamnetin, routine, myricetin, and quercetin, have the smallest bond energy, indicating that the four compounds are the most stable and have the highest potency as HMGB1 inhibitor.

Abstract

In order to promote economic independence for communities, Social Entrepreneurship promotes social activities by encouraging the local community to become engaged in Small and Medium Enterprises (SMEs) as part of Social entrepreneurship. One way SMEs may ensure their own long-term success and expand their worldwide presence is by adopting a creative economy strategy from each industry. The goal is to ensure that small and medium-sized enterprises (SMEs) in Indonesia can thrive for the long term and ultimately become the backbone of the country's economy. The focus of this study is on small and medium-sized enterprises (SMEs) with the goal of incorporating them into the expanding field of social entrepreneurship within the context of the creative economy. Data is gathered via interviews, written records, and in-person observations (qualitative, interactive analysis approach). Based on these findings, it's clear that the local government actively promotes the growth of small and medium-sized enterprises (SMEs), notably those operating in the food service industry. Social entrepreneurship that relies on the creative economy is encouraged by both the government and large corporations like Google and Facebook because of its potential to boost the economy. Government and small and medium sized enterprises (SMEs) must be involved in order to ensure the long-term success of social entrepreneurship based on the creative economy.

Abstract

This study presents a systematic literature review (SLR) to explore the role of Industry 4.0 technologies, circular economy practices, and human resource development (HRD) in enhancing performance and sustainability within the manufacturing sector. Using SLR methodology, 29 articles from accredited international journals published between 2018 and 2024 were curated and thematically analyzed based on stringent inclusion and exclusion criteria. The selected articles were organized into three main themes: Industry 4.0 Technologies, Circular Economy in Manufacturing, and HR Development and Employee Empowerment. Key findings indicate that the adoption of smart technologies, such as the Internet of Things (IoT) and artificial intelligence (AI), significantly enhances operational efficiency and competitiveness in manufacturing. Additionally, circular economy practices support sustainability through resource optimization and waste reduction. HR development plays a crucial role in facilitating technological adaptation, although challenges such as infrastructure limitations and technology-related anxiety remain significant barriers. This review concludes that collaboration among governments, companies, and educational institutions is essential to overcome these implementation challenges. Practical implications and recommendations for further research are provided to support more inclusive and sustainable adoption of Industry 4.0

Abstract

This study aims to explore the impact of BRICS dynamics on Indonesia's economic security, focusing on economic policies, financial initiatives, and geopolitical shifts involving BRICS countries. This research evaluates the effects of economic cooperation within BRICS, the launch of a new BRICS currency, and infrastructure investments funded by the New Development Bank (NDB) on Indonesia's financial stability, trade opportunities, and domestic economic policies. The findings indicate that while there are opportunities for Indonesia to expand trade and secure financing for infrastructure projects, challenges related to the volatility of the rupiah exchange rate and the potential dependence on foreign investments remain significant concerns. On the other hand, the potential for strategic cooperation in sectors such as energy, technology, and other industries could provide positive contributions to Indonesia's economy by enhancing global competitiveness and strengthening domestic economic resilience. This study is expected to provide valuable insights for Indonesian policymakers in formulating strategies to leverage the opportunities presented by BRICS dynamics while managing the risks of an increasingly complex global economy.

Abstract

Islamic banking in Indonesia has shown consistent growth, making profitability a crucial indicator of financial health and competitiveness. This study examines the effect of non-performing financing (NPF), financing-to-deposit ratio (FDR), and debt-to-equity ratio (DER) on return on equity (ROE) at BCA Syariah during 2015–2023. Using a quantitative associative design, we obtained 36 annual observations from financial statements and applied panel regression to evaluate both simultaneous and partial effects. The results indicate that NPF, FDR, and DER jointly influence ROE. Partially, NPF exerts no significant effect, FDR has a significant negative impact, while DER shows a positive but insignificant relationship with ROE. The dominance of FDR highlights the central role of liquidity management compared to credit risk and capital structure.The novelty of this study lies in its contrast with prior findings, where NPF is typically found to significantly reduce profitability. In BCA Syariah’s case, strong risk management and stable financing quality appear to mitigate the adverse effects of NPF, making liquidity pressure (FDR) the primary determinant of profitability. Theoretically, this extends the literature on Islamic banking profitability by showing that the impact of financing risk may be context-specific and shaped by internal bank governance. Practically, the findings suggest that BCA Syariah should continue improving financing quality while prioritizing stricter management of third-party funds, thereby strengthening profitability and enhancing its competitive position in the Islamic banking sector.
