Students’ Psychological Adjustment to Shift-Schooling Ecosystem in Sub-Saharan African Urban Communities
Full text linkWhile shift-schooling has been recognized for expanding educational access without large-scale infrastructural investments in marginalized communities, little is known about how adolescents in Sub-Saharan Africa psychologically adjust to these learning environments. These students face developmental challenges related to career aspirations, emotional regulation, and interpersonal relationships. Guided by adaptation theory, this study examined academic adjustment among senior high school students by focusing on psychological well-being indicators such as emotion, social relationships, and attachment. Using a survey research design with a random sample of 270 students, moderate reliability coefficients were recorded for psychological adjustment using the Student Adaptation to College Questionnaire (SACQ). Hypotheses were tested using one-way ANOVA and multiple linear regression via IBM-SPSS version 23. Results revealed that accommodation status significantly impacted psychological adjustment to shift-schooling, and gender differences influenced adjustment outcomes. School attachment and emotional and social adjustment behaviours predicted over 63% of the variance in academic adaptation. The study concluded that urban transportation challenges negatively affected non-residential students’ emotional experiences, particularly among females. These findings underscore the importance of psychological factors in shaping students' perceptions of their learning environments. Emotional and relational counseling interventions are recommended to support adolescents transitioning from basic education to senior high school in Sub-Saharan African urban settings
Academic Engagement in Students: The Role of Lecturers' Social Support Mediated by Academic Self-Efficacy and Growth Mindset
Full text linkAcademic engagement is a critical topic within the field of educational psychology, particularly in the context of higher education, due to its far-reaching positive and negative implications. Among the key antecedents believed to shape academic engagement are lecturer social support, academic self-efficacy, and a growth mindset. This study aimed to examine the extent to which academic self-efficacy and a growth mindset mediate the relationship between lecturer social support and academic engagement. The research involved 451 undergraduate students from the Greater Jakarta area, utilizing path analysis as the primary data analysis technique. The findings revealed two main outcomes: (1) lecturer social support has a significant direct effect on academic engagement, and (2) academic self-efficacy and growth mindset do not serve as strong mediators in this relationship. These results highlight the importance of enhancing lecturer support and suggest the need for targeted interventions to strengthen students’ academic self-efficacy and growth mindset within higher education institutions.
The Impact of Goal-Setting Training on Enhancing Self-Efficacy in the Dayak Entrepreneurial Community
Full text link
Entrepreneurship is a vital component of economic development, especially within ethnic communities that possess distinct cultural and social strengths. A significant challenge facing the entrepreneurial community of the Dayak tribe in Kalimantan is low self-efficacy, which refers to individuals' confidence in their ability to confront challenges and accomplish goals. This lack of confidence creates barriers to business development. This study aims to examine the impact of goal-setting training on improving the self-efficacy of Dayak entrepreneurs. The subjects of this study were 40 Dayak entrepreneurs, divided into 20 subjects in the experimental group and 20 in the control group. Data were collected using a self-efficacy scale developed by Sulistyani et al. (2022), interviews, focus group discussions, and observations. The research design employed was a pre-post control group design. The analysis was conducted using both quantitative and qualitative methods. Quantitative analysis utilized Repeated Measures ANOVA to assess self-efficacy levels among Dayak entrepreneurs following the goal-setting training. Qualitative analysis was based on observations, interviews, focus group discussions, and worksheets. The findings indicated an increase in self-efficacy scores across pre-test, post-test, and follow-up measurements, with a Mean Square value of 487.675, F = 37.205, and p = 0.000 (p < 0.05). This demonstrates an interaction between measurements (pre-test, post-test, and follow-up) and groups (experimental and control). The interaction highlights a significantly different increase in scores across the measurements between the two groups. The conclusion of this study is that goal-setting training can enhance the self-efficacy of Dayak entrepreneurs. These findings contribute significantly to the development of more effective training strategies for the Dayak community and provide a foundation for implementing goal-setting-based training programs in other ethnic communities facing similar challenges

The role of positive emotional culture as a mediator between symmetrical internal communication and organizational identification: Procedural justice climate as a moderator
Full text linkOrganizational identification is crucial for understanding how employees internalize their company’s values, goals, and identity. Understanding the dynamics of organizational identification can help companies foster a more harmonious and productive work environment and develop effective management strategies to retain and enhance employee engagement. This research aims to elucidate the role of a positive emotional culture in the relationship between symmetrical internal communication and organizational identification, moderated by procedural justice climate. 158 participants from various industries in Indonesia were involved in this study, selected through convenience sampling. Data collection was conducted via an online survey using Google Forms. Data analysis employed Model 4 and Model 14 of Hayes’ PROCESS, utilizing SPSS version 29.0.1.0. The results indicate that a positive emotional culture significantly mediates the relationship between symmetrical internal communication and organizational identification. However, there is no moderating effect of the procedural justice climate in this relationship. This research is valuable for organizational management, as it highlights the importance of fostering symmetrical internal communication to cultivate a positive emotional culture, which, in turn, can enhance employee organizational identification
Optimizing K-Nearest Neighbors with Particle Swarm Optimization for Improved Classification Accuracy
Full text linkThis study aims to improve the performance of the K-Nearest Neighbors (KNN) algorithm in classifying public reviews of Batik Madura through optimizing the K value using the Particle Swarm Optimization (PSO) algorithm. Public reviews collected from the Google Maps platform are used as a dataset, with positive, negative, and neutral sentiment categories. Optimization of the K value is carried out to overcome the constraints of KNN performance, which is highly dependent on the K parameter, with PSO providing a more efficient approach than the grid search method. However, PSO also presents challenges such as sensitivity to parameter tuning and potential computational overhead. This study has succeeded in developing a web-based system using the Python Streamlit framework, which makes it easy for users to access sentiment analysis results. Testing shows that optimizing the K value with PSO increases the accuracy of KNN to 88.5% with an optimal K value of 19. However, this accuracy is not compared to other optimization techniques, leaving its relative advantage unverified. The results are expected to help Batik Madura entrepreneurs in evaluating public perception and guiding strategic innovations. Research outputs include a prototype, intellectual property registration, and journal publication, although the role of deep learning models is only briefly noted without further development
Design of the gamifying anti-bullying education: a transformative approach with the giant snakes and ladders bullying game
Full text linkBullying in elementary school environments is a serious problem that can hinder children's emotional and social development. This study aims to provide anti-bullying education to elementary school students through interactive game media, namely Giant Bullying Snakes and Ladders. The method used was an in-depth interview with elementary school teachers in Pracimantoro District, Wonogiri Regency. This interview aims to obtain information about the forms of bullying behavior that often occur in schools and educational efforts that have been implemented previously. Based on the results of data analysis, researchers designed a creative solution in the form of an educational game that is not only fun but also full of anti-bullying moral messages. This game is designed on a large scale to attract students' attention and can be played in groups. Each box in the game contains illustrations and educational messages, such as an invitation to stop bullying and empathy for friends. The results of implementing this game show that students become more active in discussing bullying and are more courageous in saying "stop bullying" when witnessing similar incidents. This study contributes to providing innovative and fun learning media, which teachers can use to effectively instill anti-bullying values in children from an early age
Does satisfaction affect the outcomes of counseling services for college students?
Full text linkThis research aims to determine the effect of college students' or counselees' satisfaction on the outcomes of counseling services at one of the universities in Yogyakarta. The type of research is cross-sectional, with 119 counselees as the research samples. The sampling technique used was total sampling. The data collection technique was carried out by giving two questionnaires to counselees using counseling services after they completed their counseling. Questionnaire 1 contains questions regarding satisfaction with counseling services, while Questionnaire 2 contains perceived counseling results. Descriptive analysis and Spearman correlation test were carried out in this study. The results showed that 74% of clients stated they were satisfied with the services they received, and 78.2% said they would recommend the services to others. The results of the correlation test produced a coefficient of 0.588 (p<0.005), which shows a significant relationship between the client's satisfaction and the counseling outcome. Counselees feel satisfied and gain new insight from the counseling services. Counselees also found their strength, felt more hopeful, and overcame their problems after attending counseling services. The level of client satisfaction is not just a subjective statement of satisfaction but is accompanied by a real impact or result of counseling. Therefore, counseling services in higher education need to be provided, which has led to significant changes for the counselees
