The rapid development of digital technology has led to an increased adoption of digital payment methods in online transaction-based businesses. However, in practice, failures and limitations in the implementation of digital payment systems still occur, potentially disrupting transaction processes and reducing customer convenience. Payment related obstacles may result in transaction cancellations and increase the risk of customer churn. This study aims to analyze the impact of failures and limitations in digital payment methods on customer churn using a classification-based approach. The data used in this research are secondary e-commerce customer data obtained from the Kaggle platform, including transaction information, payment methods, customer behavior, and historical transaction records. The research methodology consists of data preprocessing, time-based feature engineering, and classification modeling using logistic regression, decision tree, and random forest algorithms. Model performance is evaluated using accuracy, precision, recall, F1-score, and confusion matrix metrics. The results indicate that the decision tree model demonstrates superior capability in identifying churn customers compared to the other models, although it does not always achieve the highest accuracy. In addition to digital payment methods, other factors such as purchase value, transaction frequency, purchase timing patterns, and product return rates also influence customer churn. The findings highlight the importance of optimizing digital payment systems as part of customer experience enhancement strategies and customer retention efforts in online transaction–based businesses.

The rapid growth of e-commerce has intensified competition among digital businesses, making pricing and discount strategies critical in influencing consumer purchase decisions. This study aims to examine the effect of original product price and price after discount on consumer purchase decisions on e-commerce platforms. A quantitative causal research design was employed using secondary data derived from publicly available e-commerce transaction records. Data analysis was conducted through descriptive statistics, correlation analysis, and multiple linear regression to assess the partial and simultaneous effects of pricing variables on purchase decisions, which were measured using a price-based purchase decision index. The findings indicate that both original price and discounted price have a significant negative effect on consumer purchase decisions. This suggests that lower displayed and final prices increase consumers’ likelihood of making a purchase. Furthermore, the discounted price was found to exert a more dominant influence than the original price, highlighting the importance of perceived value in online purchasing behavior. This study contributes to the digital marketing literature by providing empirical evidence on pricing effects in e-commerce and offers practical insights for e-commerce platforms in designing effective and data-driven pricing and discount strategies.

In today's digital era, social media has become an integral part of everyday life, especially for younger generations such as students. Platforms like Instagram, TikTok, Twitter, and Facebook facilitate fast and interactive communication, but often encourage the use of informal language such as abbreviations or emojis. This contrasts with the demands of the academic world. This study aims to analyze the influence of social media use on students' language styles in the academic world. The research method used was quantitative, namely observation. Observations were conducted to determine students' communication patterns on digital platforms (such as class WhatsApp group chats and comments on social media). The results showed a strong tendency to use slang, non-standard abbreviations, and code-mixing, carried over from social media habits into formal academic contexts. This phenomenon has contributed to the erosion of the boundaries between informal and formal language styles among students. This study concludes the need to strengthen formal language literacy to maintain professional communication in the academic world.

This study aims to analyze the influence of interest rates, exchange rates, and coffee production on the value of coffee exports in South Sulawesi. The background of this study is based on the condition of South Sulawesi coffee exports which have experienced significant fluctuations in recent years despite coffee production tending to increase. This study uses a quantitative approach with time series data for the period 2009-2023 sourced from the World Bank, International Monetary Fund and the Directorate General of Plantations, the Food Crops, Horticulture and Plantation Service of South Sulawesi Province. Data analysis was conducted using multiple linear regression through the EViews 12 application with the classical assumption test as a model prerequisite. The results show that partially interest rates have a significant effect on coffee exports, while exchange rates and coffee production do not have a significant effect. Simultaneously, the three independent variables do not have a significant effect on the value of coffee exports. This finding indicates that external factors, especially interest rates, are more dominant in determining the performance of South Sulawesi coffee exports than internal factors of production and exchange rates.

The interactive learning video innovation "Human Blood Circulation" through Edpuzzle, with embedded questions, is designed to address the difficulties faced by fifth-grade elementary school students in understanding abstract biological concepts. Science education in elementary schools often encounters challenges in explaining invisible processes, such as the heart's working mechanism and blood circulation, leading students to struggle with comprehension or merely memorize the material. Conventional learning videos tend to make students passive, necessitating media that can transform the learning process into an active one. Edpuzzle, as an educational platform, allows teachers to insert questions at critical points in the video, requiring students to answer before continuing to watch. This innovation aligns with the cognitive development stage of fifth-grade students, who are in the concrete operational stage.The research objectives include product development, validity and feasibility testing, analysis of conceptual understanding improvement, influence on focus and learning independence, and student responses. Media development refers to Mayer's cognitive theory of multimedia and the characteristics of interactive videos according to Heinich et al. Additionally, media development models such as ADDIE and Dick and Carey are discussed. The main benefits of using Edpuzzle include increasing engagement, facilitating real-time formative assessment, and enhancing learning motivation. However, challenges exist such as technology access, teacher readiness, the risk of technology dependency, and long-term evaluation. The practical implications can support digital learning and the transformation of elementary science education.

The shoe manufacturing industry demands a planned, integrated, and consistent production system in maintaining product quality. One of the crucial stages is the gluing process between the outsole (rubber) and the midsole (phylon), which determines the adhesive strength, comfort, and durability of the shoe. This study aims to analyze the implementation of internship activities in a series of gluing processes in the Stockfit Department of PT X. The research method uses a qualitative descriptive approach with data collection techniques through direct observation, involvement in production activities, and systematic field recording during the internship period. The analysis was carried out by linking the field findings with the operations management theory of Heizer and Render, the Crosby concept of quality management, and the principles of continuous improvement from Deming and Imai. The results of the study show that the gluing process has been systematically arranged, starting from material adjustment, primary application, the use of two types of glue, the rubber cutting process, to the final pasting. However, problems were found such as dependency between processes, inconsistency in glue thickness, as well as the influence of machine conditions and operator skills. These problems have the potential to reduce production efficiency and the quality of the final product. Therefore, it is necessary to strengthen process control and apply the principle of continuous improvement to improve overall production performance.

This research is motivated by the phenomenon of theft committed by 15-year-old adolescents in market environments, which creates tension between criminal law enforcement and the principle of child protection in the Indonesian legal system. The study aims to analyze the legal regulations of theft under the old Criminal Code (Law No. 1 of 1946), the new Criminal Code (Law No. 1 of 2023), and the Juvenile Criminal Justice System Law; to examine the criminal liability of adolescents from the perspective of criminal law theory; and to review the implementation of restorative justice and diversion. The research method used is normative legal research with statutory, conceptual, and case approaches, particularly reviewing the provisions of Article 591 of the new Criminal Code, the theory of fault, and the principle of proportionality. The results indicate that the criminal liability of children must take into account psychological limitations, maturity levels, and criminogenic factors, including the influence of the social environment. Furthermore, the mens rea element in the phrase "known or reasonably suspected" is difficult to apply in practice to transactions involving small losses, as price reasonableness can obscure indications of malicious intent. This finding affirms that imposing criminal penalties on children in cases of petty theft potentially contradicts the principles of ultimum remedium and proportionality. Therefore, law enforcement should prioritize diversion, mediation, and restorative justice approaches by involving families and communities to achieve substantive justice and prevent excessive criminalization of children.

A moral crisis occurs when a person loses the attitude, character, and behavior that are in accordance with goodness. Moral and ethical crises often occur among the younger generation in Indonesia due to various factors, such as the impact of globalization, the influence of social media, the lack of parental involvement, and the lack of character education in schools. This study aims to explore the relevance of character education values in M. Quraish Shihab's Tafsir Al-Mishbah to the problems faced by students in the contemporary era. The crisis of morality, bullying, and the threat of radicalism are the background to the urgency of internalizing contextual Qur'anic values. This research is qualitative in nature, using library research, a thematic approach, and content analysis. The results show that the concept of character education in Tafsir Al-Mishbah is rooted in the relationship between the meaning of Rabb and tarbiyah, which aims to shape Insan Kamil through intellectual and spiritual balance. Analysis of Q.S. Luqman: 12-13, Q.S. Al-Hujurat: 11-13, and Q.S. Al-Mujadilah: 11 reveals fundamental values such as monotheism, gratitude, tolerance, and manners in seeking knowledge. The relevance of the findings shows that Quraish Shihab's moderate (wasathiyah) thinking is very effective in protecting students from extreme ideas, building digital literacy ethics through the principle of tabayyun, and eliminating the culture of violence in schools through a humanistic approach. This study concludes that Tafsir Al-Mishbah offers a functional methodological framework for strengthening the character of 21st-century students.

The rapid development of social media has made fashion brands, especially modest fashion, increasingly collaborate with influencers to increase brand awareness. This study discusses the role of influencer credibility in increasing brand awareness of the brand @zaskiasungkarjakarta through Instagram content. The method used a case study with a qualitative approach. Data was collected through interviews and documentation, then analyzed through the stages of data reduction, presentation, and drawing conclusions. The results show that influencer credibility plays a significant role in maintaining brand awareness. There are three main dimensions that are visible: expertise, trustworthiness, and attractiveness. Trustworthiness is evident from the honesty and consistency of influencers when showing or reviewing products. Meanwhile, attractiveness arises from the match between the influencer's lifestyle and image with the brand, making the audience feel more relatable and trusting. Overall, influencer credibility helps increase brand awareness from the brand recognition stage (people start to recognize), brand recall (people can remember again), until the brand finally becomes top of mind in the minds of the audience.

Background: Preschool age, which is 4-6 years, is a crucial stage in child development. Delays in development and growth in children will have long-term impacts on their cognitive, social, and emotional abilities. Children's diet and parenting styles are greatly influenced by their growth and development. Objective: This study aims to examine how parenting styles and nutritional status are related to the development of preschool children. Method: This study used a quantitative approach with a cross-sectional design and involved fifty parents of preschool children aged between 4 and 6 years. Total sampling was used as the sampling technique. To conduct bivariate analysis, researchers used the Spearman rank correlation test. PSDQ or Parenting Styles and Dimensions Questionnaire was used to collect data on parenting styles, Denver Developmental Screening Test II (DDST II) was used to assess child development, and Z scores were used to determine the child's nutritional status. Results: The majority of respondents indicated an authoritative (democratic) parenting style (88%), good nutritional status (88%), and normal child development (80%). There was a significant correlation between parenting style and child development, with p = 0.004 and r = 0.405. Meanwhile, for nutritional status and child development, the p value was 0.013 with r = 0.351. Conclusion: Nutritional status and democratic parenting style were significantly correlated with preschool children's development. Education on balanced parenting and nutrition needs to be strengthened through family-based nursing interventions.

Online gambling has emerged as a growing public health and social concern, particularly in developing countries with rapid digitalization such as Indonesia. Increased internet accessibility, mobile device usage, and financial technology services have facilitated the widespread adoption of online gambling across diverse age groups, including adolescents. This study aims to investigate the phenomenon of online gambling and identify key determinants contributing to addictive gambling behavior. The method used is a narrative literature review, synthesizing findings from national and international studies related to online gambling, behavioral addiction, psychological mechanisms, and socio-environmental factors. The findings indicate that online gambling addiction is influenced by multiple interrelated determinants, including economic pressure, cognitive distortions such as illusion of control, low legal awareness, environmental exposure, and technological features embedded in gambling platforms. Neurobiologically, repetitive gambling behavior is reinforced by dysregulation of the brain’s reward system, particularly dopamine pathways, which strengthens compulsive engagement despite adverse consequences. Psychosocial impacts include increased risk of anxiety, depression, financial instability, social isolation, and criminal behavior. The study also highlights that adolescents are particularly vulnerable due to developmental factors and peer influence. The implications of these findings emphasize the need for comprehensive prevention strategies involving stricter legal enforcement, public education, mental health interventions, family support, and technological regulation. A multidisciplinary and public health–oriented approach is essential to reduce the prevalence of online gambling addiction and mitigate its long-term psychological, social, and economic consequences.
