This research aims to systematically examine the strategic role of family businesses in entrepreneurship education for students with special needs in Indonesia. Entrepreneurship education has become an important approach to increase economic independence, especially for individuals with special needs who face challenges in accessing formal employment. Family business as a family-based economic unit has great potential as a contextualized, flexible and supportive means of entrepreneurship learning. This Systematic Literature Review (SLR) analyzes 25 relevant national and international journal articles, published between 2019-2025, with a focus on the integration of family business in entrepreneurship education for people with disabilities. The results show that family businesses can provide an inclusive learning environment, build practical skills, and strengthen family involvement in the education process. However, challenges still arise in the form of limited resources, access to training and supporting policies. This study recommends the need for collaboration between schools, families and government in designing a family business-based entrepreneurship curriculum that is adaptive to the needs of students with special needs. The findings make an important contribution to the development of a more inclusive and sustainable entrepreneurship education model in Indonesia.

The Covid-19 pandemic brought some challenges to the continuity of educational activities around the world. In the Indonesian context, the government mandated the shift from face-to-face classrooms to online learning which burdened science teachers in maintaining laboratory instructions. Due to the closure of the schools, Indonesian secondary science teachers were forced to alter their methods of laboratory instruction by integrating digital technologies. Therefore, a qualitative methodology and a case study method were used to investigate the experiences of Indonesian secondary science teachers in conducting laboratory learning amid the Covid-19 outbreak. Moreover, the TPACK framework was utilised as a theoretical basis to map participantsâ€™ experiences. The data was obtained using semi-structured interviews with open-ended questions with two Indonesian secondary science teachers. The data then was analysed using a thematic analysis strategy to identify themes that emerged from the participantsâ€™ experiences. The emerging themes were choosing teaching content, teaching science concepts that require laboratory activities, using digital technology to facilitate students in conducting laboratory activities, using digital technology to assess studentsâ€™ laboratory learning outcomes, and facing challenges in integrating digital technology into laboratory teaching. These experiences were mapped into a number of TPACK knowledge domains, such as CK, PK, PCK, TK, TCK, TPK, and XK, using the TPACK framework as a guide. However, no indication of TPCK was found in the participantsâ€™ experiences.

This study pioneers the mapping and analysis of the blue economy's potential across the 35 regencies/municipalities of Central Java by constructing a novel Blue Economy Index (BEI). Notably, this research is among the first in Indonesia to build the BEI using granular satellite data and digital sensor information, and to apply the Two-Step System GMM approach to dynamically analyze the factors influencing its development. This combination provides unprecedented sub national detail and robust insights into effective policy levers. The findings reveal significant disparities among the southern coastal, northern coastal, and non-coastal areas. The southern coastal regions exhibit higher BEI values compared to their northern coastal and non-coastal counterparts, which fall below the average. Results from the Two-Step System GMM regression analysis indicate that internet usage, infrastructure, and the COVID-19 period exert significant effects on the BEI. Specifically, infrastructure development, proxied by Nighttime Light (NTL), demonstrates a negative impact on the BEI, suggesting that environmentally unsustainable infrastructure may undermine the sustainability of the blue economy. Meanwhile, access to digital technology through internet usage plays a crucial role in fostering inclusive blue economy growth. Based on these findings, the proposed policy recommendations include optimizing environmentally friendly infrastructure development, leveraging digital technology to expand market access, and strengthening the resilience of the blue economy through Adaptive-Responsive-Innovative (ARI) crisis policies. Consequently, the development of the blue economy in Central Java is expected to enhance the sustainable welfare of coastal communities while fully optimizing the potential of coastal areas.

Analisis dilakukan menggunakan rubrik berbasis kerangka TPACK. Hasil penelitian menunjukkan bahwa calon guru mampu merancang kursus yang terstruktur dengan tujuan pembelajaran yang jelas, organisasi pembelajaran yang sistematis, serta pemanfaatan fitur Moodle secara fungsional. Namun, pemanfaatan fitur lanjutan LMS untuk mendukung alur pembelajaran dan umpan balik masih terbatas. Temuan ini menunjukkan bahwa MooDIY berpotensi mendukung pengembangan kompetensi pedagogik dan teknologis dasar calon guru. Kata Kunci: calon guru; learning management system; pengetahuan pedagogis; pengetahuan teknologis; MooDIY Abstract This study analyzes the pedagogical and technological knowledge of pre-service Information Technology teachers as reflected in MooDIY-based course design artifacts. A descriptive qualitative research design was employed. The research subjects consisted of two groups of students enrolled in a Learning Management System course in the Information Technology Education program during the 2025/2026 academic year. Both groups implemented Project-based Learning (PjBL) and developed MooDIY-based course projects with different instructional topics. Data were collected through document analysis of the course design artifacts, including learning outcomes, instructional organization, learning activities, assessments, and LMS feature utilization. The artifacts were analyzed using a rubric adapted from TPACK-based LMS evaluation frameworks. The results indicate that the pre-service teachers were able to design structured online courses with clear learning objectives, coherent instructional organization, and functional use of core Moodle features. However, the use of advanced LMS features to support learning progression and feedback was limited. Overall, the findings suggest that MooDIY is an accessible and pedagogically meaningful platform for developing foundational pedagogical and technological competencies in pre-service teacher education.

Anxiety is an emotional response to situations perceived as threatening, and in the context of practical learning, anxiety can affect students' readiness, concentration, and performance. This study aims to analyse students' anxiety levels during computer assembly practice in the Information Technology Education study program. The method used was descriptive quantitative, involving 80 students as respondents. The research instrument was a five-point Likert scale questionnaire to measure anxiety levels. The results showed that students' anxiety levels were in the moderate to high category, with anxiety about technical errors and assembly procedures as the highest indicators. This finding indicates that students feel stressed by the possibility of errors and uncertainty in following the assembly stages. The findings of this study indicate the need for a more supportive learning approach, such as technical assistance, simulations, and project-based learning, to reduce anxiety. The limitation of this study lies in the quantitative approach that has not explored psychological factors in depth. Therefore, further research is recommended using a qualitative or mixed approach to better understand the dynamics of student anxiety in technical practice.
