Abstract

This study aims to analyze the influence of price, product quality, brand image, and promotion on Oppo smartphone purchase decisions, with consumer satisfaction as a mediating variable among students at Nusa Bangsa University. The research method used a quantitative approach with a causal associative approach. The sample consisted of 147 respondents selected using purposive sampling. The research instrument, a Likert-scale questionnaire, was then tested for validity and reliability. Data analysis was performed using multiple linear regression and a mediation test using SPSS version 25. The results showed that price, product quality, brand image, and promotion had a positive and significant influence on purchase decisions. Furthermore, price, product quality, brand image, and promotion also significantly influenced consumer satisfaction. Furthermore, consumer satisfaction was shown to act as a mediating variable in strengthening the relationship between price, product quality, brand image, and promotion on purchase decisions. These findings confirm that a marketing strategy that emphasizes a combination of competitive pricing, superior quality, a strong brand image, and appropriate promotion can increase consumer satisfaction and purchase decisions.   Keywords: Price, Product Quality, Brand Image, Promotion, Consumer Satisfaction

Abstract

This study aims to understand the investment decision-making strategies of institutional investors on the Indonesia Stock Exchange, emphasizing three main aspects: financial information management, market sentiment, and issuer reputation. The research method used is a descriptive qualitative approach, with data collected through documentation and non-participatory observation from credible online sources, followed by thematic analysis. The results indicate that investment decisions are not solely determined by conventional financial indicators but are also significantly influenced by market perception and company reputation. Financial information serves as the basis for objective evaluation, market sentiment influences asset allocation preferences, and issuer reputation is a differentiating factor in assessing long-term investment viability. The study's conclusions confirm that these three factors form a complementary ecosystem of information and perception, making institutional investment decisions a complex process that demands data accuracy, responsiveness to sentiment, and reputation consistency.   Keywords: Institutional Investment, Financial Information, Market Sentiment, Issuer Reputation

Abstract

This study aims to implement the Decision Tree C4.5 algorithm in the classification of permanent employee appointments at PT Intinusa Teknik Sejahtera to support more objective, accurate, and transparent decision-making. The research method used is a quantitative data mining-based approach with the CRISP-DM framework, using an employee dataset from the HRD department consisting of 16 attributes related to profile and performance. The modeling process was performed using RapidMiner Studio software using the split validation method with a ratio of 80% training data and 20% test data. The results show that the Decision Tree C4.5 classification model has an accuracy of 89.25%, with recall for the Contract class of 91.14% and the Permanent class of 78.57%, and precision for the Contract class of 96.00% and the Permanent class of 61.11%. The conclusions of this study confirm that the attributes of Performance, Attendance, Loyalty, and Tenure are the main factors in permanent employee appointments, and the C4.5 algorithm can be utilized as an HRD decision support system, although further method development is needed to improve precision for the Permanent class.   Keywords: Decision Tree C4.5, Classification, Permanent Employees, Human Resource Management
