Abstract

Nationwide, school violence and bullying occur. Most instances occur between the first and second years of high school and might be physical (hitting, kicking, or hair pulling) or verbal. Classroom, small group, and computer-based training are provided. After a socialization session, participants were given a questionnaire to learn what they knew and wanted to know about school violence prevention, physical, verbal, and digital violence, early signs of violence, sexual violence, and bullying vs. joking. This socialization report analyzes the pre- and post-test results of training on handling physical, verbal, and online sexual harassment for 67 SMAN 07 Medan students using the Normalized Gain (N-Gain) approach. The Youth Red Cross 006 of SMAN 07 Medan arranged the workshop to study student bullying and physical, verbal, and cyber sexual violence. This research encompasses students from SMAN 7 Medan, specifically from grades X (17), XI (17), and XII (33). Student N-Gain scores increased significantly for male (0.88) and female (0.94) pupils. The training outcomes suggest schools need to hold annual sexual violence and bullying prevention training and outreach initiatives. To maintain student knowledge, schools should incorporate related resources into the curriculum or guidance and counseling. Thus, universities might develop research-based training modules for secondary schools to combat violence and bullying.

Abstract

The purpose of this research is to examine the relationship between customer satisfaction and retention for air conditioners (ACs) sold in retail stores in Medan, as well as the impact of the marketing mix. This quantitative study surveyed 1,614 AC buyers from 14 retail stores in Medan (May–September 2025) and analyzed the data using PLS-SEM to test validity, reliability, and hypothesis significance. The results show that all four marketing mix variables significantly affect customer satisfaction, with place (store location and accessibility) having the strongest influence, followed by price and product, while promotion negatively affects satisfaction. Customer satisfaction strongly predicts loyalty, and loyalty significantly influences customer retention. The mediation analysis confirms that loyalty and satisfaction together enhance the effects of marketing mix variables on retention, although promotional efforts can reduce satisfaction and weaken retention when poorly executed. By examining the air conditioner market in Indonesia through the 4P marketing mix framework and the satisfaction-loyalty-retention linkages in the retail sector, this study adds to the marketing literature. The results shed light on an understudied aspect of retention in the air conditioner market—the importance of store accessibility and customer experience—and provide managers with insight into how to optimize location, service, and value-based strategies rather than relying solely on price or promotion. These findings suggest that management needs to focus on strategic locations and quality service to improve customer satisfaction. Businesses are advised to shift from aggressive promotions to value strategies such as after-sales service and loyalty programs.

Abstract

Country of origin has been widely acknowledged as an important extrinsic cue influencing consumer purchase decisions; however, empirical evidence explaining its indirect mechanisms through marketing-related constructs in local brand contexts remains limited. This study aims to examine the effect of country of origin on purchase decisions, incorporating brand equity, service quality, and promotion as explanatory constructs within a structural model. A quantitative research design was employed using survey data collected from 384 university students in Medan, Indonesia, who had purchased and used Ventela shoes. Data were analyzed using Structural Equation Modeling–Partial Least Squares. The results demonstrate that the country of origin has a significant positive effect on purchase decisions. In addition, the country of origin significantly influences brand equity, service quality, and promotion, which in turn positively affect purchase decisions. The structural model indicates that brand equity, service quality, and promotion play important mediating roles in strengthening the relationship between country of origin and purchase decisions. Overall, the model explains a substantial proportion of variance in purchase decisions, highlighting the robustness of the proposed framework. This study extends the country-of-origin literature by providing empirical evidence on the indirect pathways through which country-of-origin perceptions shape consumer behavior toward local footwear brands in emerging markets. In practice, the findings offer strategic insights for local brand managers on leveraging brand equity, service quality, and promotional activities to enhance consumer purchase decisions.

Abstract

The rapid growth of the retail coffee industry in Indonesia has intensified competition, requiring firms to understand the determinants of customer loyalty beyond physical store design. This study aims to examine the effect of store atmosphere on customer loyalty, with customer satisfaction and purchase intention as mediating variables, in a drive-thru coffee retail context in Medan. The population comprised all customers who made purchases at the Kopi Kenangan Gatot Subroto outlet in Medan, and data were gathered utilizing a non-probability purposive sampling method. A total of 389 valid responses were obtained from customers who had made at least one purchase and were willing to complete the questionnaire. Data were analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM). The results indicate that customer satisfaction has a strong and significant direct effect on customer loyalty (β = 0.746, p < 0.001), and purchase intention indirectly influences loyalty through satisfaction. However, store atmosphere does not significantly affect satisfaction, purchase intention, or loyalty. The model explains 56.2% of the variance in customer loyalty, indicating moderate predictive power. These findings emphasize that post-consumption evaluation and experiential satisfaction play a more critical role than atmospheric cues in building loyalty in the modern coffee retail industry.

Abstract

This study analyzes the effect of product design and country of origin on purchase decisions, with price discount as a moderating variable, in the context of Mitsubishi Electric air conditioners in Medan, Indonesia. A quantitative explanatory approach was applied using purposive sampling. Data were collected from 400 consumers who had purchased Mitsubishi Electric air conditioners and were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The findings indicate that product design and country of origin do not significantly influence purchase decisions. In contrast, price discount has a strong and significant positive effect on purchase decisions. The moderating role of price discount on the relationship between product design and purchase decision is not supported. These results suggest that economic considerations, particularly promotional pricing strategies, are more influential than intrinsic product attributes or country-of-origin perceptions in shaping consumer decisions about durable home electronics in competitive markets.

Abstract

Purpose: This study examines how strategic marketing drivers influence perceived marketing performance in the air conditioner industry and highlights the roles of competitive advantage and technological turbulence in an emerging-market context. Methodology: This study used a quantitative explanatory approach and analyzed data from 398 air conditioner consumers in Medan City, Indonesia, using SmartPLS. Results: Product differentiation strongly and significantly strengthens competitive advantage, and pricing strategies significantly improve perceived marketing performance. Perceived marketing capabilities also enhance competitive advantage, although they shape performance primarily through indirect pathways. Electronic word?of?mouth, brand reputation, competitive advantage, and technological turbulence do not significantly predict perceived marketing performance directly. These statistically non-significant paths clarify important boundary conditions: middle-income urban consumers who purchase durable goods, such as air conditioners, pay more attention to functional product attributes and value-for-money considerations than to reputational signals, online buzz, or environmental turbulence when they evaluate marketing success. Conclusions: The findings indicate that, in the air conditioner market in emerging urban settings, firms that emphasize product uniqueness and value-based pricing achieve superior perceived marketing performance, while reputational, e-WOM-related, and turbulence-related factors play more selective and context-dependent roles. Limitations: This study focuses on Medan City and perceived marketing performance, which narrows the generalizability of the findings to other regions, segments, and industries. Contributions: This study advances the strategic marketing literature by presenting an integrated model that identifies which strategic marketing drivers most effectively build competitive advantage and perceived marketing performance and by demonstrating when widely cited drivers exert weaker direct effects.
