Abstract

This study examines the efficacy of the Linear Congruent Method (LCM) in enhancing the integrity of Computer-Based Testing (CBT) systems through optimized question randomization. The primary objective was to evaluate how LCM can prevent question leakage and cheating by ensuring each test is unique and unpredictable. The research involved conducting 20 tests with different students, using both randomized and non-randomized settings to compare outcomes. Results indicated that LCM significantly improves test fairness and security by distributing questions in a manner that prevents predictability. Furthermore, this approach allows educators to accurately assess individual student understanding and tailor educational interventions effectively. Recommendations for future research include refining LCM parameters, integrating additional security technologies, and continuous evaluation to maximize the educational and integrity benefits of CBT systems.

Abstract

This study analyzes the defense mechanisms of marginalized characters in the novel Sisi Tergelap Surga by Brian Khrisna. The research was conducted as a library study without a specific location, using primary data in the form of the novel’s text and secondary data from books, journals, and relevant scientific articles. The population of the study includes all marginalized characters in the novel, while the sample was determined through excerpts depicting defense mechanisms. The researcher acted as the research instrument, assisted by a data recording guide using the read-and-record technique. Data analysis was carried out descriptively and qualitatively using the interactive model of Miles and Huberman, which includes data reduction, data display, and drawing conclusions. The results show that marginalized characters face social pressures, internal conflicts, and injustice by employing defense mechanisms such as repression, projection, rationalization, and displacement. Repression is shown through the suppression of feelings and experiences that cause anxiety, projection through the transfer of guilt and faults onto others, rationalization through logical justification of painful actions or conditions, and displacement through the venting of negative emotions toward safer targets. These defense mechanisms enable the characters to maintain psychological balance amid a life full of pressure, while also reflecting the social, economic, and structural impacts on the mental condition of marginalized groups. The findings contribute to the study of literary psychology, particularly regarding the representation of mental health among marginalized groups in contemporary Indonesian novels.

Abstract

This study analyzes the persuasive strategies used in the Sayang Hijab version of the Sayang detergent advertisement that uses Dr. Tirta as an expert endorser. This study was conducted to uncover the mechanism of medical authority construction and persuasive strategies used in the Sayang Hijab version of the Sayang detergent advertisement, which involves Dr. Tirta as an expert endorser. This study uses a qualitative descriptive method with the Critical Discourse Analysis (CDA) model from Norman Fairclough’s theory. Norman Fairclough’s CDA theory has three dimensions: text analysis, discourse practice, and sociocultural practice. The results of this study indicate that in the text analysis, Dr. Tirta as an expert endorser in this advertisement uses medical language to create new standards of cleanliness and safety in the advertisement of detergent products. In this discourse practice, there is a synergy of authority between the emotional experience of consumers, as depicted by Ria Ricis & Moana, and the rational validation of medical experts, as depicted by Dr. Tirta. From a sociocultural perspective, this detergent advertisement reflects a shift in public mindset after the pandemic, where there is an increased reliance on expert judgment rather than domestic decisions. This study concludes that the use of laboratory settings and medical attributes is not only about the marketing appeal of an advertisement, but is more an attempt to reposition detergent from a household necessity to a preventive health instrument.

Abstract

This study aims to analyze the effectiveness of the application of Augmented Reality technology. Reality (AR) in improving the short story writing skills of high school students, who still face obstacles in developing ideas, narrative structure, and learning motivation. The study used a quasi-experimental design with a pre-test and post-test. control group This design involved 60 eleventh-grade students at SMA Negeri 1 Jombang. Data were collected through short story writing tests, motivational questionnaires, and interviews, and analyzed using paired- reference tests. sample t- test, independent t- test, and effect The results showed that the experimental group using AR experienced a significant increase compared to the control group, with an average score increase of 25.95% compared to 7.05%. Statistical tests showed a significant difference (p < 0.05) with an effect The size of the medium-high category. In addition, students' learning motivation in the experimental group was higher (8.5/10) than in the control group (6/10). These findings indicate that AR effectively improves the quality of short story writing in terms of ideas, narrative structure, and language style, as well as increasing student engagement in learning. This study contributes to the development of technology-based writing learning models by systematically integrating AR into the writing process. The limitations of the study lie in the limited duration of the intervention and the narrow sample scope. Future research is recommended to test the implementation of AR on a wider scale and over a longer period.
