This study examines customer churn prediction in subscription-based telecommunications from a digital marketing perspective using machine learning. The analysis utilizes a secondary dataset of 7,043 customer records that simulate behavioral, contractual, and financial attributes commonly found in telecom services. Three classification algorithms Logistic Regression, Random Forest, and Gradient Boosting are applied to model churn behavior. Data preprocessing includes handling missing values, encoding categorical variables, and splitting data into training and testing sets. Model performance is evaluated using accuracy, recall, and ROC-AUC, with emphasis on recall due to its importance in identifying at-risk customers. The results show that Gradient Boosting achieves the highest overall performance with an ROC-AUC of 0.84, while Logistic Regression provides relatively higher recall. Key drivers of churn include short-term contracts, higher monthly charges, and lower service engagement. However, recall remains moderate, indicating limitations in capturing complex behavioral factors. These findings suggest the need to combine predictive models with behavioral insights and highlight the importance of early customer engagement and long-term retention strategies.

The purpose of this study is to examine how online promotion, product innovation, and brand image affect product competitiveness in Batam City's flower bucket equipment industry (CV Acmeteam). This study employs a quantitative methodology, gathering information from 100 respondents via questionnaires using Simple Random Sampling with Slovin formula from a population of 135 active customers. Data were analyzed through validity tests, reliability tests (Cronbach's Alpha = 0.750), classical assumption tests (normality, multicollinearity, heteroscedasticity), multiple linear regression, partial t-test, simultaneous F-test, and coefficient of determination (R²). Results show that all questionnaire items are valid and reliable. The normality test (Asymp. Sig. = 0.866 > 0.05) indicates normally distributed data, and no multicollinearity (VIF < 10) or heteroscedasticity (Sig. > 0.05) was detected. Regression analysis reveals that online promotion (β = 0.521, Sig. = 0.041), product innovation (β = 0.668, Sig. = 0.033), and brand image (β = 0.458, Sig. = 0.049) each significantly influence product competitiveness. Simultaneously, all three variables are significant (F = 9.876, Sig. = 0.000) and explain 44.9% (R² = 0.449) of product competitiveness variance. Product innovation is the strongest predictor. This study concludes that strong brand image, continuous product innovation, and effective digital marketing are essential pillars for enhancing product competitiveness. Business actors must optimize these three elements to compete effectively in an increasingly open creative industry market.

The relationships between variables were analyzed using the Spearman correlation test with a significance level of p < 0.05. The results showed that magnesium intake demonstrated a significant inverse relationship with pain intensity, indicating that higher magnesium intake was associated with lower menstrual pain levels. In addition, WHR was also significantly associated with dysmenorrhea among adolescent girls. Overall, it can be concluded that magnesium intake and WHR are related to the occurrence of dysmenorrhea.

Construction firms listed on the Indonesia Stock Exchange from 2022 to 2024 serve as the focus for investigating how financial distress and firm size impact audit delay, utilizing a quantitative framework anchored in multiple linear regression analysis. Secondary data sourced from the companies' financial statements underpin this examination, where financial distress receives measurement via the Zmijewski model and firm size finds proxy through the natural logarithm of total assets. The timeliness of financial reporting directly tied to audit delay holds paramount importance, as delays compromise information quality available to stakeholders. Partial tests reveal no significant effects from either financial distress or firm size on audit delay, a pattern echoed in simultaneous assessments showing joint insignificance of these variables. Such outcomes point to external influences outside the modeled scope, notably operational complexity, auditor quality, and procedural technicalities in auditing, as primary drivers of delays. For practitioners, these insights underscore the necessity of bolstering internal operational efficiencies alongside enhanced auditor collaborations to expedite financial disclosures. Subsequent investigations ought to incorporate further pertinent variables, fostering deeper and more holistic insights into the phenomenon.
