The COVID-19 pandemic has significantly impacted the health, economy, and social sectors, and micro, small, and medium-sized enterprises (MSMEs) worldwide, including in Indonesia. This paper examines the use of social media and e-commerce with an entrepreneurial orientation to enhance the business performance of MSMEs. The study should serve as a model for improving the quality of micro, small, and medium-sized enterprises in the Jambi Province, in Indonesia. The research employs quantitative and qualitative approaches. The latter method employs in-depth interviews, focus group discussions (FGDs), and observation, whereas the former uses the partial least squares method (PLS). The findings and discussions conclude that social media adoption positively affected the performance and entrepreneurial orientation of MSMEs during the said period. Similarly, e-commerce positively affected the performance and entrepreneurial orientation of MSMEs. Entrepreneurialism and social media adoption had a significant impact on the performance of MSMEs, and due to its entrepreneurial orientation, e-commerce influenced the performance of MSMEs.

This study aims to develop a learning model that can foster science literacy skills by involving ‘the ability to think critically, think creatively, and collaborate skills. Three research questions were asked: i) how to develop learning models to cultivate skills (science literacy, critical thinking, creative thinking, and collaboration); ii) how to validate it; and iii) how critical thinking, creative, and collaboration skills affect science literacy skills. This research uses analysis, design, development, implementation dan evaluation (ADDIE) development design by using validation sheets as data collection instruments: three learning model experts and two lecturers who teach introductory physics courses as practitioners participated in this research. The collected data is analyzed using V-Aiken to determine the level of validity. Overall, the validation results from model development are in the “meet requirements” and “feasible” categories for implementation. The analysis results of the relationship of research variables show that critical thinking, creative thinking, and collaboration directly affect science literacy skills; however, critical thinking and creative thinking skills have a moderate effect on science literacy skills if collaboration skills act as mediation.

Metaphor is a powerful cognitive tool to understand or develop mathematical concepts. Although metaphor has been progressively recognized in mathematics education, there is an inadequate systematic review of its application and achievement. Therefore, this study aims to investigate and map metaphors studies trends in mathematics education. Data were collected from a systematic review of 70 metaphor studies in mathematics education published from 2012–2021 using the PRISMA guidelines. The results showed the mapping of the metaphor studies' attributes in mathematics education. Future research can use this information as the basis for determining the novelty of research related to metaphors. Furthermore, they can use this information to determine its potential and opportunities for future research. The primary limitation of this review is related to the sensitivity of the search strategy, which makes it impossible to cover relevant studies comprehensively.

Numeracy skills are essential for prospective mathematics teachers as they bridge mathematical concepts with real-life applications. However, many prospective mathematics teachers face challenges in applying these concepts to practical situations. This study aims to analyze the conceptual and procedural errors made by prospective mathematics teachers when solving numeracy problems within the context of "Save Our Water." A descriptive research design was employed, utilizing a numeracy test adapted from the Minimum Competency Assessment (MCA) and semi-structured interviews as research instruments. The study involved 30 prospective mathematics teachers from the University of Jambi, Indonesia. The findings revealed that conceptual errors primarily stemmed from reliance on rote memorization of formulas without a deeper conceptual understanding. Procedural errors were attributed to difficulties in unit conversion, incorrect formula application, and improper manipulation of formulas. To address these issues, the study recommends incorporating contextual approaches, problem-based learning, and project-based learning strategies that connect mathematical concepts to real-world contexts. Additionally, the use of visual aids, such as diagrams and 3D models, is suggested to enhance conceptual understanding and strengthen the connection between abstract concepts and practical applications. Future research should investigate the effectiveness of these instructional approaches in improving numeracy skills and enhancing the teaching readiness of prospective mathematics teachers.

The purpose of this research is In 21st century learning students are required to be more active in learning than teachers, therefore this study aims to determine whether there is an influence between the LAPS-Heuristic learning model and the ability to solve problems. Methodology: Using quantitative descriptive. Where, the number of samples in this study were 436 students from SMP 11 Jambi City who used purposive sampling technique. Data were then analyzed with the help of SPSS 21 application to find descriptive statistics in the form of mean, min, max, and category as well as inferential statistics using simple regression. Finding: The results obtained in this study are dominant both in the ability of student problem solving and the effectiveness of the LAPS-Heuristic learning model in mathematics lessons. With this, it is strengthened by the existence of a relationship and influence between the LAPS-Heuristic learning model and the students' problem solving abilities seen from the sig value below 0.025, which is 0.019 and has a contribution of 70.3%.

Developers or users of an application that utilizes various databases demand accurate data through a web service, and it is a challenge to provide a trusted web service. This study aims to develop a trusted mechanism in building the Universitas Jambi's web service by applying the ADDIE model. Data from the web service will be queried by a Databorang Application. The trusted mechanisms produced in this study are: 1) Analysis of data and information requirements, 2) Web service design, 3) Development of web service which has procedures: query development, validation of queries by experts, validation of results from users through the Databorang application, 4) Implementation, and 5) Evaluation. In a restricted deployment it was revealed that the user strongly believes in the truth of the data / information displayed by the application of Databorang. In line with the increasing data retrieval functions on the webservice, it is hoped that the webservice can act as the data center of the University of Jambi in the future.
