This study aims to quantitatively test the impact of using audiovisual media in learning Al-Qur'an interpretation on students' understanding. This study was motivated by the low level of students' understanding observed when the interpretation material was delivered through conventional teaching methods. Using a quantitative approach with a quasi-experimental design, this study adopted a pretest-posttest model involving an experimental group and a control group. The sample consisted of 62 students, divided into an experimental group exposed to audiovisual media and a control group taught through traditional lectures. Data collection instruments included questionnaires and comprehension tests given before and after the intervention. The results of the t-test analysis revealed a significant difference between the two groups (p < 0.05), indicating that the use of audiovisual media had a positive and significant effect on improving students' understanding of Al-Qur'an interpretation.

Color fastness in Direct to Film (DTF) digital screen printing is influenced by various external factors, one of which is exposure to ultraviolet (UV) light. This study aims to evaluate the impact of UV light on the color stability of DTF prints on two types of fabric, namely 30s cotton and spandex rayon. A quantitative approach was used in this study, involving color difference testing (ΔE), washing simulations, and UV exposure. Based on the analysis results, cotton 30s demonstrated superior color fastness performance compared to spandex rayon, as indicated by lower ΔE values after UV exposure and washing processes. Conversely, spandex rayon experienced more drastic color changes, especially after being washed with bleach detergent. These findings emphasize that the selection of fabric materials and washing methods are critical factors.

This research method uses literature studies and case analysis to understand the dynamics of social problems in elementary schools. The results of the study indicate that social problems in elementary schools are often related to bullying, difficulty interacting with peers, and the influence of the school environment. The impact of these problems can be emotional stress, decreased academic achievement, and difficulty in building healthy social relationships. This study recommends the importance of early intervention and support from teachers and parents to overcome social problems in elementary schools and create a safe and supportive school environment. Thus, students can develop optimally and achieve their academic and social potential.

The film Tuhan Ijinkan Aku Berdosa presents an in-depth description of moral and spiritual conflict through the inner turmoil experienced by the main character. This abstract explains that the factors underlying the conflict are complex and interrelated, including psychological conditions, social backgrounds, and religious aspects that underlie the lives of the characters. Conflict does not only arise from external events, but also as a result of the clash between values that are normatively believed by a Muslim and the reality of life that takes actions that deviate from Islamic teachings. The main character grew up in a stressful environment, marked by poverty and social alienation, so that he felt he had no other choice but to take a path that was considered morally wrong. A deep sense of guilt also emerged as a consequence of behavior that was contrary to religious values, which then triggered a spiritual conflict that further complicated his inner state. In addition, a weak understanding of religious teachings and a lack of spiritual guidance also played an important role in exacerbating the conflict. When individuals grow up without strong religious direction or feel alienated from the religious community, they tend to seek meaning and salvation in deviant ways, thus becoming further from the path that is approved by God.

This study aims to determine the effect of organizational involvement on students’ learning behavior at Universitas Negeri Medan. The research is motivated by the observation that student participation in campus organizations may have both positive and negative impacts on academic learning. A quantitative method with an ex post facto approach was employed. A total of 163 students were randomly selected from the population of active members across 12 Student Activity Units (UKM). Data were collected using a closed-ended questionnaire with a Likert scale. The results showed that students' level of organizational activity was generally high, with the majority classified under the "high" category. Meanwhile, the learning behavior of students actively involved in organizations was categorized as "fairly good", with an average score of 79. Based on regression analysis, a negative and significant effect of 15.8% was found between organizational involvement and learning behavior. This means that the more active students are in organizational activities, the more likely their learning behavior declines. These findings highlight the importance of time management and academic awareness to help students balance organizational commitments with their learning responsibilities.

Global brands increasingly rely on emotional branding to foster consumer loyalty, yet its effectiveness varies across cultural contexts. Many organizations continue to adopt universal emotional strategies without accounting for how cultural values shape emotional perception and brand attachment. This study explores how emotional branding drives customer loyalty through constructs such as brand love, attachment, trust, and self-congruity, and how these mechanisms are moderated by cultural dimensions including individualism–collectivism, communication context, and power distance. Findings indicate that emotional appeals resonate differently depending on local cultural norms: collectivist and high-context societies respond more positively to subtle, relational branding, while individualist and low-context cultures favor explicit, identity-centered emotional messaging. Strategic implications highlight the importance of culturally adapted storytelling, platform-specific messaging, and authenticity in emotional branding execution. Brands that align emotional content with local cultural expectations are more likely to foster sustained loyalty. Further research is encouraged to examine emotional branding in emerging markets and digital ecosystems to advance culturally responsive global marketing practices.

This study aims to identify the factors associated with malaria incidence and evaluate the effectiveness of prevention and control programs that have been implemented. A quantitative approach with a descriptive correlational research design was used, involving secondary data from the Health Office reports and primary data collected through field surveys in the endemic area of PT. Tandan Sawita Papua, Keerom Regency. The results showed that malaria incidence is associated with the use of mosquito nets and the use of mosquito repellents. The study concludes that an integrated approach to malaria control is essential, including community education, environmental improvements, and sustainable health policy support.

Gamification has become a new approach in education that offers a more interactive and enjoyable learning experience. The challenge of maintaining students' motivation to learn encourages educators to look for alternative methods that are more in line with the characteristics of today's digital generation. Gamification is present as a potential solution to overcome boredom in the traditional learning process. This study aims to analyze the effectiveness of gamification-based learning methods in improving student learning outcomes and motivation. The study used a quantitative approach with a quasi-experimental design involving an experimental group and a control group. The research instrument consisted of a learning outcome test and a learning motivation questionnaire. Data analysis was carried out by normality, homogeneity, independent sample t-test, and paired sample t-test. The research sample was taken from junior high school students with a total of 60 participants who were divided equally into two groups. The results of the study showed a significant improvement in student learning outcomes and motivation after the implementation of gamification. The experimental group showed higher posttest scores and motivation scores than the control group. Gamification-based learning has proven to be effective in creating a more engaging and productive learning atmosphere. This study concludes that gamification is not only able to improve academic achievement, but also strengthen students' emotional involvement in the learning process. These findings serve as a conceptual and practical basis for the development of future learning strategies that are more adaptive and responsive to the times.

This study aims to examine the practice of elopement (kawin lari) and its legal consequences from the perspective of Batak Angkola customary law, as well as its relation to Law Number 1 of 1974 on Marriage. The research was conducted in Sibangkua Village, Angkola Barat District, South Tapanuli Regency. The method used is an empirical legal approach, with data collected through observation and interviews with traditional leaders, religious figures, village officials, and individuals involved in elopement. The findings reveal that elopement frequently occurs in Batak Angkola society, mainly due to high dowry demands, disapproval of arranged partners, or violations of social and religious norms. The resolution process is carried out through customary stages such as mandokon ulang agoan, marsapa adat, and patibal sere. Although the national marriage law does not explicitly regulate elopement, it is recognized within Batak Angkola custom and has a structured resolution mechanism. Nevertheless, socially, elopement is often viewed negatively and may damage the family’s honor.
