The increasing number of international students in Indonesia's higher education sector urges institutions to improve the quality of their services, facilities, and education. The teaching and learning environment is critical, encompassing the effectiveness of instructional methods, classroom interactions, and the academic support systems provided by the university. Additionally, their socio-experiences, including integration into the campus community and interactions with peers, play a crucial role in their overall well-being and academic success. This study aims to explore the life and academic experiences of international students in undergraduate International Programs at the University of Jambi in Indonesia. This research employed a mixed-method approach, combining a questionnaire adapted from the Strategy Inventory for Language Learning (SILL) and in-depth interviews, with a total of 13 international students from international classrooms participating in the study. The research highlights significant challenges for international students at the University of Jambi, including inadequate classroom and laboratory facilities, poor lighting, and insufficient resources, particularly in Animal Sciences and Agriculture. Language barriers due to Indonesian being the primary medium of instruction further hinder learning. Students express high dissatisfaction with services such as insurance, health facilities, extracurricular activities, and counseling, though library services are well-regarded. Recommendations include adopting English for instruction, providing bilingual training for lecturers, and improving infrastructure and student services to enhance the overall academic experience for international students

This research highlights the importance of numeracy as one of the indicators in assessing a country's progress. Numeracy bridges mathematical theory with practical application and can be used in everyday decision-making, such as financial decisions, health literacy, and risk assessment. However, the Minimum Competency Assessment results show that more than 50% of students still need to be in the low numeracy competency category. This research aims to explore the mathematical reasoning processes of pre-service mathematics teachers in solving travel route problems to understand their analytical skills. This research uses a qualitative descriptive approach with data collected from 30 fifth-semester mathematics education students at the University of Jambi. Data were obtained through numeracy tests, observations, and semi-structured interviews, allowing in-depth analysis of the participants' mathematical reasoning processes in solving contextual problems. Participants were asked to solve problems related to the context of travel routes, focusing on time and cost efficiency in choosing travel routes. The research results show that most participants can understand and model the problem, although there are differences in their approaches to solving it, ranging from very analytical to simple. Some participants initially misunderstood the problem, but after being given the opportunity for reflection, they were able to improve their understanding and the solutions produced. This research concludes that fostering mathematical reasoning in teacher training programs is crucial for improving numeracy skills. Sustained practice, reflection, and a structured problem-solving approach are necessary to help prospective teachers analyze and interpret mathematical problems more effectively. Keywords: mathematical reasoning, problem-solving, route travel, and pre-service mathematics teachers. DOI: http://dx.doi.org/10.23960/jpmipa/v25i2.pp712-727

The purpose of this research is to produce valid, practical and effective Flipped Classroom-based mathematics learning tools and to improve students' mathematical communication skills. The method used in this research is the Ploom development model. The development of the Plomp model is namely the initial investigation phase, the development phase, and the assessment phase. Learning tools developed in the form of lesson plans, student worksheets and learning videos. The subjects of the field test were students and educators in class X of SMAN 3 Jambi for the 2020-2021 academic year. The research instruments used were instruments at the initial investigation stage, validity test instruments, practicality test instruments and effectiveness test instruments. The results of the validation of the Flipped Classroom-based mathematics learning device were valid in terms of construct and content. The validity values obtained for lesson plans, learning videos, and worksheets are 3.41; 3.17; and 3,4. Flipped Classroom-based math learning tools are practical in terms of implementation and ease of use. The results of the questionnaire analysis of the student's practicality data showed a figure of 81% so that it was categorized as practical from the observation data on the implementation of learning and interviews. The resulting learning devices are effective in improving students' mathematical communication. The results of the final test of students' mathematical communication skills are 77.78% of students who have scored above the KKM.

The aim of this research is to find out whether there is an influence on the ability to understand mathematical concepts based on Van Hiele theory on the learning outcomes of STKIP Muhammadiyah Sungai Penuh students. The research method that will be carried out is associative (correlational) research. Sample determination was carried out using random sampling technique or determining samples randomly after carrying out a normality test, test homogeneity and equality of means tests. The results of the calculations carried out obtained the calculated r value = 0.5 46 and r table = 0.444, apparently r count > r table , then it can be concluded that H 1 accepted , so it can be concluded that there is a significant relationship between learning interactions and results learn mathematics with interpretation Enough. Coefficient of determination (r)2 = 0.2981 . So the magnitude of the relationship between variable X and variable Y is 29.81 %. This means that the relationship between the ability to understand mathematical concepts and the learning outcomes of transformation geometry is 29.81 %.

Current solar panel maintenance often involves manual, rooftop fieldwork, which introduces significant fall-from-height risks and occupational hazards. To address this, this research investigates the integration of the Internet of Things (IoT) to streamline and enhance operational efficiency. The goal is to develop an IoT-enabled solution for user-driven routine maintenance that can significantly mitigate occupational hazards and reduce maintenance duration. This system is designed to optimize the long-term energy yield of solar panels by preventing the typical efficiency decline caused by neglected upkeep. The study employs a prototype development method (literature review, construction model design, and control system development). The final system leverages common consumer-grade terminal devices (smartphones, laptops) to provide a ubiquitous, real-time control interface, allowing users to manage the system remotely via a stable network connection.

One of the most important and potential problems encountered in an official online letter management application is the recipients' late response. This action research aims to improve the recipients' response time and determine the central core of shyness according to response time categories: less than 24 hours (green zone); between 24 hours to 48 hours (orange zone); and more than 48 hours (red zone) in managing formal online letter management system at Jambi University. Using the social representation theory of shyness as the basis of action adopted from Moscovici theory [1], it is hypothesized that response time displaying will impact response time improvement. A survey questionnaire distributed to 129 respondents showed a significant improvement in the participants' response time, respectively, in cycles 1 and 2. The zone group increased percentage sed from 22.44% to 52.49 % in the first cycle, and it ultimately raised to 62.38% at the end of the second cycle. Such an increase might be due to the users' efforts to avoid the level of shyness, which were classified into: (1) slow to respond and (2) personal or work unit late response time â€“ both marked in red. It is recommended that social shyness incorporated in improving response time in a formal online letter can be further implemented with other social and psychological parameters. The application will illustrate computer systems' interaction on social society to implement regulations both in institutions and in government.
