The implementation of the ‘Freedom to Learn Curriculum’ in higher education can serve as a catalyst for the nation’s future advancement, yet how to realize this potential remains a critical question. This study implements an integrated Problem-Based Learning (PBL) model to enhance students’ ability to solve economic and business problems across time. The research integrates several stages: identifying root problems, theoretical and applied reviews, analyzing government policies in practice, assessing impacts, and developing future problem-solving programs. This research aims to examine the effect of the problem-solving learning model on improving students’ ability to address economic problems, focusing on strengthening self-identity and enhancing both group and individual work abilities. The research design employed a pre-experimental approach, starting with problem identification, theoretical foundation development, field exploration, analysis of supporting policies, and identification of potential impacts for the future. The subjects were 118 students enrolled in the Introduction to Economic Theory course at the Faculty of Economics and Business, Universitas Negeri Malang. Data on improvements in problem-solving ability, operational skills, individual work changes, and teamwork-based problem-solving capabilities were processed using SPSS-23 through ANCOVA with regression analysis. Meanwhile, improvements in problem management and opportunity recognition in economic activities were analyzed using SWOT through group work mechanisms. The process emphasized optimizing accessibility to problem-based activities and varying fieldwork and practical exercises for managing progressive life challenges. The results showed that based on the ANCOVA statistical analysis, the Problem-Based Learning (PBL) model had a significant effect on students’ ability to develop alternative solutions, particularly through teamwork. In the Tests of Between-Subjects Effects model involving two independent variables—CVMT (PBL-based treatment) and TI (individual task category)—the overall model was significant, with a Sig. value of 0.008. This indicates that the combination of PBL treatment and variations in individual assignments jointly influenced students’ group task outcomes. The individual task variable (TI) significantly affected group performance with a significance value of 0.049 and a Partial Eta Squared value of 0.137, indicating a moderate contribution. This means that the type or quality of individual tasks completed by students has a tangible impact on group work success. Descriptive Statistics results showed that the highest average group task scores came from students with individual task categories at scores of 85 (mean = 86.21) and 88 (mean = 86.00), indicating that students with strong individual performance tended to demonstrate better group outcomes. Conversely, groups with lower individual scores (TI = 75) also had lower group performance (mean = 74.65). This supports the assumption that success in group work originates from solid individual contributions. From the Parameter Estimates results, a significant difference was specifically found between the TI = 75 group and the reference group (TI = 90) with p = 0.032, showing that students with lower individual performance exhibited a statistically significant difference in group outcomes

This study explores the implementation of circular economy principles within Safina Quilt, an MSME in Balikpapan that transforms textile waste—such as fabric scraps and discarded clothing—into value-added products. Safina Quilt applies the concepts of reduction, reuse, and upcycling throughout its production processes using quilting techniques, while simultaneously establishing an inclusive supply chain that engages local tailors, individuals with disabilities, and homemakers. This business model not only delivers economic gains by increasing profit margins and expanding market reach but also generates substantial social benefits by empowering vulnerable community groups. Although challenges remain, including limited access to supporting materials, constraints in production capacity, and insufficient digital marketing efforts, Safina Quilt demonstrates how MSMEs can successfully integrate environmental, economic, and social sustainability. Strengthening supply chain mechanisms, enhancing production capabilities, and improving digital marketing strategies are essential for scaling up and ensuring long-term business sustainability.

This study aims to analyze the application of franchising systems in street food businesses and their impact on improving the competitiveness of MSMEs. Culinary MSMEs, especially in the street food sector, have high growth potential but face various challenges such as weak branding, inconsistent product quality, and limited managerial capacity. The franchising and micro-franchising models have emerged as potential strategies to overcome these challenges through operational standardization, management support, and brand strength. This study uses a qualitative approach with a case study method through in-depth interviews and observations of street food business actors who are franchisees. The results show that the implementation of SOPs, training, and supervision from the franchisor improve operational efficiency, product consistency, brand identity, and consumer trust. In addition, franchising has been proven to expand market access, increase sales, and help street food businesses move upmarket. However, the study also found challenges such as limited innovation, dependence on the franchisor for raw materials, and the burden of royalty fees. Overall, the franchising system has proven to be an effective strategy for increasing the competitiveness of MSMEs in the street food sector through a combination of standardization, brand strengthening, and ongoing management support.

This study investigates the role of higher education institutions (HEIs) in strengthening social entrepreneurship ecosystems in Malang Raya, Indonesia. Using an explanatory sequential mixed-method design, quantitative data were collected from 100–150 respondents representing key ecosystem actors, including faculty members, students, social entrepreneurs, supporting institutions, and government stakeholders. Quantitative data were analyzed using Structural Equation Modeling (SEM) with LISREL software, while qualitative data from 15–25 key informants were analyzed thematically through in-depth interviews and focus group discussions (FGD). The study integrates Resource-Based View (RBV), Triple Helix Model, and Social Capital Theory to develop a comprehensive framework. Findings demonstrate that HEIs significantly influence ecosystem sustainability, although some relationships show non-significant effects due to external factors and institutional readiness. The study recommends implementing collaborative strategies based on the triple helix model and strengthening social capital to enhance the social entrepreneurship ecosystem. This research contributes to advancing community-based entrepreneurship theory and provides practical implications for policymakers and institutional leaders in Indonesia.

Numerous challenges arise concomitant with the rapid advancement of technology through digital marketing models that have been deployed by several small enterprises to rival comparable products. The transition to the digital market owing to the Industrial Revolution and the COVID-19 pandemic poses both threats and opportunities for technology-driven multinational corporations and micro and small enterprises. Nevertheless, only a few entrepreneurs have been able to capitalise on these prospects. In 2022, the significance of non-traditional media in science and technology for developing new product marketing capabilities that are autonomous, adaptable, and environmentally attuned is becoming more evident. It is crucial to establish entrepreneurship programmes tailored to the needs and requirements of 25 UMK students as per their respective groups and technical disciplines. Programmes should be customised to suit the capabilities, requirements, and preparedness of each department to facilitate the development of an entrepreneurial culture. An attempt has been made to establish synergy bridges using a specific approach. This approach can be implemented progressively and steadily for a particular cohort of skilled businesses or simultaneously for a variety of target groups. An organised campaign is required to foster an entrepreneurial culture through education and training of the target groups. The Programme for the Application of Science and Technology in Business (P2M) will be executed by LPM to enhance the entrepreneurial aptitude of 25 UMK students. This project intends to develop the business skills of the participants while maintaining objectivity in its evaluations. The use of simple sentences and causal connections facilitates the comprehension and logical coherence of the text. Consistent formatting and a conventional structure have been employed, while a high register and precise vocabulary have been utilized to maintain a balanced, value-neutral tone. Grammatical correctness has been ensured through careful editing. The Programme for the Application of Science and Technology in Business (P2M) will be executed by LPM to enhance the entrepreneurial aptitude of 25 UMK students.
