Abstract

This study aims to analyze the effectiveness of mediation services in improving students’ interpersonal relationships at SMK Swasta Kristen Tomosa 2. Interpersonal conflicts characterized by miscommunication, unhealthy competition, and peer disputes have negatively affected the learning climate, highlighting the need for empirically tested interventions. This research employed a quantitative approach with a pretest–posttest control group design. A total of 30 students were selected through simple random sampling and assigned to experimental and control groups. Data were collected using a Likert-scale questionnaire that met validity and reliability criteria (Cronbach’s alpha > 0.60). Data analysis included normality and homogeneity tests, an independent sample t-test, and N-Gain analysis. The results revealed a significant difference between the experimental and control groups (sig. 2-tailed = 0.000 < 0.05). The experimental group achieved an average N-Gain score of 66% (moderate category), while the control group obtained 17% (low category). These findings indicate that mediation services are effective in enhancing students’ interpersonal relationships, particularly in terms of trust, openness, communication skills, and constructive conflict resolution.

Abstract

This study was motivated by the low level of students’ honesty character, reflected in behaviors such as cheating, lying, and denying mistakes at SMK Negeri 3 Hiliserangkai. The research aimed to analyze the effect of classical guidance services and information services on improving students’ honesty character, both simultaneously and partially. A quantitative associative approach was employed using multiple linear regression analysis. The population consisted of 190 students, with a purposive sample of 30 eleventh-grade TKJ students. Data were collected through a closed-ended questionnaire that had been tested for validity and reliability, and were analyzed using prerequisite tests and regression hypothesis testing. The findings revealed that classical guidance and information services had a significant effect on enhancing students’ honesty character, both jointly and individually. Improvement was indicated by the difference in scores before and after the intervention. These results confirm that structured guidance and counseling interventions are effective in strengthening the internalization of honesty values and contribute significantly to the reinforcement of character education in schools.

Abstract

This study examined the effectiveness of group guidance services employing role-playing techniques in reducing social anxiety among eighth-grade students. A quantitative approach was applied using a quasi-experimental one-group pretest–posttest design. The population consisted of 60 students, and 30 participants were selected through purposive sampling based on initial screening results indicating moderate to high levels of social anxiety. Data were collected using a Likert-scale social anxiety questionnaire developed from established theoretical indicators and tested for validity and reliability through a pilot study. Data collection was conducted in two stages: pretest administration prior to the intervention and posttest following four structured treatment sessions. Data analysis began with prerequisite tests, including normality (Shapiro–Wilk), homogeneity (Levene’s test), and linearity, confirming that the data met parametric assumptions. Hypothesis testing was conducted using a paired sample t-test, followed by multiple regression analysis to examine simultaneous effects, and the coefficient of determination (R²) to measure effect size. The findings revealed a statistically significant decrease in social anxiety scores after the intervention, with an effective contribution of 66.8%, indicating both statistical and substantive impact of the treatment.
