Abstract

Eel fish (Anguilla marmorata (Q.) Gaimard) oil is a valuable source of health-promoting unsaturated fatty acids. Adsorbent selection during the bleaching stage of fish oil purification can significantly impact the final product quality.  This study aimed to evaluate the impact of different adsorbents on the quality of refined eel fish (Anguilla marmorata (Q.) Gaimard) oil. Eel fish oil was extracted using Soxhlet extraction with diethyl ether and purified through degumming, neutralization, and bleaching stages. Various adsorbents (bentonite, magnesol XL, and zeolite) were employed at different concentrations (1% bentonite, 3% magnesol XL, and 5% & 10% zeolite activated by acid and base) to remove impurities. The refined oils were analyzed for physical, chemical, and microbiological properties. Results showed that all adsorbents effectively improved the quality of eel fish oil, meeting most International Fish Oil Standard (IFOS) and Indonesian National Standard (SNI - 8467:2018) criteria. However, density and iodine values were below the specified limits. Microbiological analysis confirmed the absence of contamination, but lead levels exceeded the permissible standard.

Abstract

Tujuan dari adanya penelitian ini adalah untuk melihat dampak Current Ratio (CR) dan Debt to Equity Ratio (DER) terhadap nilai perusahaan, yang dinilai menggunakan Price to Book Value (PBV), pada perusahaan di sektor transportasi dan logistik yang tercatat di BEI selama periode 2020-2024. Metode kuantitatif yang diterapkan adalah data sekunder yaitu laporan keuangan tahunan perusahaan terkait, yang selanjutnya dianalisis melalui regresi data panel dengan menggunakan model Common Effect Model (CEM), Fixed Effect Model (FEM), dan Random Effect Model (REM). Uji Chow dan Hausman dilakukan untuk menentukan model terbaik, yang akhirnya menunjukkan bahwa model FEM yang paling sesuai. Temuan parsial mengungkapkan bahwa CR tidak memberi pengaruh signifikan terhadap nilai perusahaan, sementara DER memberi pengaruh positif yang signifikan. Secara bersamaan, CR dan DER mempengaruhi nilai perusahaan secara signifikan. Kesimpulan penelitian ini adalah bahwa struktur modal lebih dominan dalam meningkatkan nilai perusahaan dibandingkan likuiditas di sektor transportasi dan logistik selama periode studi.

Abstract

Multinational capital budgeting is a long-term investment decision-making process undertaken by multinational corporations, considering various cross-border factors. Unlike domestic capital budgeting, multinational capital budgeting faces additional complexities such as currency exchange rate fluctuations, differences in tax systems, political risk, global economic risk, and regulatory differences in host countries. This study aims to analyze the concept and practice of multinational capital budgeting and examine the risks and managerial implications that arise in its implementation. The research method used is a descriptive qualitative approach through a literature review of national and international journals, international finance textbooks, and the company's financial reports and official publications. A case study of PT Garuda Indonesia (Persero) Tbk is used to provide an empirical overview of the challenges of multinational capital budgeting, particularly those related to international funding and exchange rate risk. The study results indicate that cross-border investment decisions that are not balanced with adequate risk analysis can create significant financial pressures and threaten the company's sustainability. Therefore, multinational capital budgeting needs to be conducted comprehensively, considering aspects of profitability, risk, and long-term financial resilience.
