Abstract

The swift expansion of social media utilization has positioned Generation Z among the primary demographics in acquiring and disseminating information. The substantial frequency of social media engagement along with the standard of information obtained impacts information-sharing behaviour, rendering a classification model essential for determining behavioural patterns. This research seeks to apply the Decision Tree algorithm to classify the information-sharing behaviour of Generation Z according to the variables of Information Quality (X1) and Social Media Usage Intensity (X2), as well as to deploy the classification model within a web-based system. The inquiry utilized a quantitative methodology adopting the CRISP-DM framework, comprising Business Understanding, Data Understanding, Data Preparation, Modeling, Evaluation, and Deployment. The empirical data were gathered via questionnaires administered to 113 Generation Z participants actively engaging with social media across Semarang Regency. The classification model was constructed utilizing RapidMiner, whereas its effectiveness was assessed employing a Confusion Matrix. The findings demonstrated that the Decision Tree algorithm attained an accuracy rate of 82.61% and produced 13 decision rules capable of classifying information-sharing behaviour into three tiers: high, moderate, and low. The constructed model was effectively integrated into a web-based application built with PHP and MySQL, allowing the classification procedure to operate automatically according to user entries. These outcomes reveal that the Decision Tree algorithm not merely delivers a classification model with robust performance, but also admits effective integration into a web-based system to assist the classification of Generation Z's information-sharing behaviour.

Abstract

This study aims to examine the influence of social influence, facilitating conditions, and performance expectancy on the adoption of the QRIS digital payment application. A quantitative approach was employed, involving a sample of 60 Generation Z respondents aged 18–28 years who reside in Central Java Province. Respondents were selected using a non-random sampling technique with purposive sampling. Primary data were collected through questionnaires using a Likert scale to measure respondents’ perceptions of social influence, facilitating conditions, performance expectancy, and digital payment adoption. Data analysis was conducted using multiple linear regression with the assistance of SmartPLS 4.1.1.2 software. The results of the statistical analysis demonstrate that social influence, facilitating conditions, and performance expectancy each have a positive and significant influence on QRIS digital payment adoption. The findings are supported by both partial and simultaneous hypothesis testing, indicating that these three factors contribute to users’ decisions to adopt QRIS as a digital payment application. The findings provide practical and policy implications for QRIS digital payment platform owners to improve service facilities, user support, and perceived benefits, thereby increasing the value and convenience experienced by users.

Abstract

This study aims to examine the influence of affiliate marketing on increasing impulsive buying among Generation Z users of TikTok Shop, with customer trust serving as a mediating variable. Employing a quantitative approach, the study collected data from 100 respondents residing in the Solo Raya region using a non-probability purposive sampling technique; a questionnaire utilizing a 1–5 Likert scale served as the research instrument. Data analysis was conducted using Structural Equation Modeling-Partial Least Squares (SEM-PLS) with the aid of SmartPLS software (version 4.1.1.8). The findings indicate that affiliate marketing has a positive and significant effect on impulsive buying, and consumer trust is likewise shown to have a positive and significant impact on impulsive buying. Furthermore, consumer trust acts as a mediator linking the influence of affiliate marketing to impulsive buying. Theoretically, this study provides an empirical contribution to the literature regarding the role of consumer trust within the digital marketing ecosystem, particularly on social commerce platforms such as TikTok Shop.

Abstract

The proliferation of feature innovations on e-commerce platforms like Shopee in Indonesia has transformed consumer shopping habits. This research aims to provide a comprehensive overview of the impact of Live Streaming Selling (LSS), Cash on Delivery (COD) services, and Online Customer Reviews (OCR) on purchase conversion. The study involved 47 employees of the Cilacap District Court (8 judges, 32 civil servants, and 7 government employees under work agreements/PPPK) as respondents, selected via a census technique. A 5-point Likert scale was used to standardize responses during data collection, followed by analysis using multiple linear regression. The findings demonstrate that all variables exert a significant positive impact, both individually and collectively. Online Customer Reviews emerged as the variable with the strongest influence (β = 0.387; sig. = 0.000), followed by Live Streaming Selling (β = 0.312; sig. = 0.000) and Cash on Delivery (β = 0.241; sig. = 0.004). The coefficient of determination (0.742) indicates that 74.2% of the variation in purchase decisions can be explained by these three variables through the regression equation: Y = 2.145 + 0.312X₁ + 0.387X₂ + 0.241X₃.

Abstract

This study aims to examine the mediating effect of CORTEX on the relationship between attitudes toward tax socialization and individual taxpayer compliance among Generation Z (Gen Z). A quantitative research approach was employed using a questionnaire consisting of closed-ended questions as the primary data collection instrument. The study population comprised Gen Z individual taxpayers residing in Semarang Regency. A total of 75 respondents were selected using a non-probability sampling method with a purposive sampling technique based on predetermined criteria. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS version 4.1.1.8. The results demonstrate that CORTEX plays a mediating role in the relationship between tax socialization and individual taxpayer compliance. The findings further indicate significant relationships between tax socialization, CORTEX, and taxpayer compliance, suggesting that effective tax socialization and the implementation of digital tax administration can contribute to strengthening taxpayer compliance among Gen Z. These findings emphasize the importance of integrating tax education and digital taxation services to support taxpayers in fulfilling their tax obligations. Although numerous previous studies have investigated factors influencing tax compliance, this study provides initial empirical evidence regarding the mediating role of CORTEX in linking attitudes toward tax socialization with individual taxpayer compliance, particularly among Gen Z taxpayers in Semarang Regency. The findings are expected to provide insights for improving tax socialization strategies and optimizing CORTEX implementation to support more effective and accessible tax administration for younger taxpayers.

The development of e-marketplaces in Indonesia, particularly Shopee, has driven increasingly fierce digital-based business competition, especially in targeting Generation Z as active users. This study aims to analyze the influence of affiliate marketing and online customer reviews on Generation Z's purchase decisions on the Shopee e-marketplace. Respondents in this study were Generation Z aged 18–25 years who resided in Central Java Province. The sampling technique used purposive sampling with a sample size of 75 people. Data collection was carried out through a questionnaire based on a 1–5-point Likert scale. The data analysis technique used was multiple linear regression with the help of SmartPLS 4.1.1.8 software. The results showed that affiliate marketing and online customer reviews, both partially and simultaneously, had a positive and significant effect on purchasing decisions. This finding indicates that the more effective the affiliate marketing strategy and the more positive customer reviews, the higher the tendency of Generation Z to make purchasing decisions on Shopee. This study provides theoretical contributions to the development of digital marketing literacy as well as practical implications for e-marketplace management in formulating strategies based on young consumer behavior.
