Abstract

The aims of this research is to determine the effect of ROA, DAR and NPM on stock prices. The population of this research are manufacturing companies in the Cosmetics and Household sub-sector which are listed on the Indonesia Stock Exchange (BEI) in 2018-2022. Purposive sampling appliied as the sampling method, and according to the established criteria, there were fives companies that met the criterias to be sampled. Quantitative methods with multiple linear regression analysis tools applied in this research. This research showed that Return On Assets (ROA) partially had a positive and significant effect on stock prices. Meanwhile, the Debt to Assets Ratio (DAR) and Net Profit Margin (NPM) partially have a negative and insignificant effect on stock prices. The Coefficient of Determination value (R2) is 0.566 which indicates that stock price as a variable Y is influenced by Return On Assets (X1), Debt to Asset Ratio (X2), and Net Profit Margin (X3) of 56.6%, while the other 43.4% is influenced by other variables outside the variables studied. Keywords: Return on Assets, Debt to Assets Ratio, Net Profit Margin, Stock Prices, Cosmetics & Household.

Abstract

Penelitian ini berupaya untuk menyelidiki dampak kualitas layanan mobile banking terhadap peningkatan kepuasan nasabah. Titik fokus penelitian berpusat pada mahasiswa Universitas HKBP Nommensen dari Fakultas Ekonomi dan Bisnis yang terdiri dari 1799 orang. Dengan menggunakan teknik Non-Probability Sampling, khususnya simple random sampling, sampel yang dipilih adalah sebanyak 95 orang. Data primer dikumpulkan melalui pemberian kuesioner. Untuk meneliti data, peneliti menerapkan metode kuantitatif, menggunakan alat analisis regresi linier sederhana. Temuan penting dari penelitian ini secara jelas menunjukkan korelasi yang kuat dan positif antara kualitas layanan dan kepuasan pelanggan, dibuktikan dengan nilai t-hitung yang melampaui nilai t-tabel (15,190 > 1,66140), dan nilai signifikansi 0,000 yang lebih rendah dari tingkat signifikansi yang telah ditentukan, yaitu 0,10. Koefisien determinasi (R2) telah dihitung sebesar 0,683, sehingga menunjukkan bahwa 68,3% kepuasan pelanggan (variabel Y) dapat dikaitkan dengan tingkat kualitas layanan (variabel X), sedangkan 31,7% sisanya disebabkan oleh variabel lain yang berada di luar lingkup penelitian.

Abstract

This study examines the determinants of Quick Response Code Indonesian Standard (QRIS) mobile payment usage within religious organizations by applying an extended Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) framework. The model integrates perceived risk, perceived security, and exposure to innovation, while testing geographic location as a moderating variable. Using a quantitative approach, a survey was conducted among 4,516 congregants of the Huria Kristen Batak Protestan (HKBP) Church across 32 districts in Indonesia, and the data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS. The results indicate that performance expectancy, facilitating conditions, habit, perceived security, and exposure to innovation significantly influence QRIS usage, with habit emerging as the most dominant predictor. In contrast, effort expectancy and perceived risk do not show significant effects, suggesting that ease of use has become standardized and institutional trust mitigates perceived risk in this context. Geographic location significantly moderates the effects of effort expectancy, facilitating conditions, and habit, highlighting the role of regional digital infrastructure disparities. The model explains 74.7% of the variance in QRIS usage. This study contributes to the literature by extending UTAUT2 into a trust-based non-profit institutional context and introducing geographic moderation in digital payment adoption research, while providing practical insights for policymakers and religious institutions to design more inclusive and infrastructure-sensitive digital financial strategies.
