Gensen Fisher Sitompul, Roberto Roy Purba, Elisabet Tambunan, Mery Lani Purba
Abstract: Growing environmental awareness has pushed companies in the bottled water industry to adopt sustainable marketing strategies, yet the effectiveness of green marketing and green pricing on consumer purchase decisions remains… ins inconsistent across studies. This study aims to analyze the effect of green marketing and green price on the purchase decision of Aqua bottled water in Helvetia Medan, both partially and simultaneously. The research applied a quantitative explanatory design. Because the population size was unknown, the sample of 96 respondents was determined using the Lemeshow formula with purposive sampling, targeting consumers who had purchased the product more than five times. Data were collected through an online questionnaire using a five-point Likert scale, tested for validity through Pearson Product Moment correlation and for reliability through Cronbach's Alpha, then analyzed using classical assumption tests and multiple linear regression in SPSS version 26. The results show that green marketing has a positive and significant effect on purchase decisions (t = 2.334; sig. 0.045), while green price also exerts a positive and significant effect (t = 9.118; sig. 0.000) with a more dominant contribution. Simultaneously, both variables significantly influence purchase decisions (F = 408.051; sig. 0.000), explaining 89.8% of its variance.

Abstract: A medical summary is a synopsis of the medical services provided to a patient. However, at Budhi Asih Regional General Hospital (RSUD), 228 files (76%) were found to have issues regarding medical aspects, reflecting the… low quality of medical summaries for sepsis patients. This study aimed to analyze the influence of length of stay and disease severity on the quality of medical summaries for hospitalized JKN (National Health Insurance) patients with sepsis at RSUD Budhi Asih. A quantitative approach with a cross-sectional design was employed, covering the period from October to December 2025. The sample consisted of 183 medical records selected using total sampling. Data were collected through a review of medical record documents. The results showed that 147 files (80.3%) fell into the low-quality category, while 36 files (19.7%) were of high quality. The average length of stay was 8.09 days with a variation of 4.31 days, while disease severity was predominantly Severity Level III, affecting 146 patients (79.8%). Logistic regression analysis revealed that length of stay and disease severity simultaneously had a significant effect on medical summary quality (p=0.004). Individually, length of stay did not have a significant effect (p=0.615), whereas disease severity did (p=0.001). The Nagelkerke R² value of 0.094 indicates that these two variables explain 9.4% of the variation in medical summary quality. Hospitals are advised to pay greater attention to the quality of medical summaries, particularly for patients with prolonged hospital stays and high disease severity.

Abstract: This research examines the quality of academic services at Muhammadiyah University of West Sumatra (UMSB) as a strategy in responding to competitive dynamics in the higher education sector. The study aims to predict service… ice quality and student satisfaction at Muhammadiyah University of West Sumatra by adopting a Machine Learning approach that combines predictive analysis methods of Linear Regression and Naive Bayes classification. The research utilized a primary dataset encompassing 2,000 student respondents through stratified random sampling technique. The novelty of this research lies in the integration of the SERVQUAL instrument with computational algorithms to generate deeper and more measurable identification of satisfaction factors. Research findings reveal variations in the level of dominance across the five measured dimensions. The Assurance, Reliability, and Empathy dimensions respectively occupy the top three ranks as the most dominant dimensions (average above 0.220). Meanwhile, the Tangibles and Responsiveness dimensions occupy the lowest ranks, with Responsiveness being the weakest aspect (0.146) and therefore requiring more attention for improvement. Model reliability was evaluated using accuracy, precision, recall, and F1-score metrics, as well as error measurement through RMSE and MAE. This research provides practical contribution in the form of strategic recommendations for university management to implement data-driven service improvements while serving as a foundational framework for the development of an integrated student satisfaction monitoring system within the academic information ecosystem.

Abstract: Abstract: This study aims to analyze stock price developments, fundamental performance, and stock valuation as a basis for determining investment decisions in banking companies listed on the Indonesia Stock Exchange during… ng the 2020–2025 period. The research objects consist of PT Bank Central Asia Tbk (BBCA), PT Bank Rakyat Indonesia (Persero) Tbk (BBRI), PT Bank Mandiri (Persero) Tbk (BMRI), and PT Bank Negara Indonesia (Persero) Tbk (BBNI). This study employs a quantitative approach using secondary data obtained from financial statements, annual reports, and historical stock price data. The analysis was conducted using panel data regression, with Earnings Per Share (EPS), Return on Assets (ROA), and Return on Equity (ROE) as independent variables and stock price as the dependent variable. In addition, stock valuation was conducted using the Price Earnings Ratio (PER) and Price to Book Value (PBV) to determine investment decision alternatives. The results show that EPS, ROA, and ROE do not have a significant partial effect on stock prices. However, simultaneously, the three variables have a significant effect on stock prices. The Fixed Effect Model produces a coefficient of determination of 91.63%, indicating that stock price variation can largely be explained by the model and the individual characteristics of each company. The valuation results show that in 2025, the four stocks were relatively undervalued compared to their respective historical averages. Based on the combination of valuation results and fundamental conditions, BMRI and BBRI are categorized as buy, BBCA as buy/hold, while BBNI is categorized as buy speculative/hold. Keywords: Stock Price, EPS, ROA, ROE, PER, PBV, Investment Decision.   Abstrak: Penelitian ini bertujuan untuk menganalisis perkembangan harga saham, kinerja fundamental, dan penilaian harga saham sebagai dasar dalam menentukan keputusan investasi pada perusahaan perbankan selama periode 2020–2025.
