Abstract

The rapid integration of web-based platforms in higher education highlights the importance of usability and user experience in supporting students’ extracurricular activities. This study evaluates the usability and user experience of the Student Extracurricular Information System (SINEMA) developed at Tadulako University. A total of 99 respondents participated, selected from a population of 5,581 active users through Slovin’s formula. Two standardized instruments were applied: the System Usability Scale (SUS) to capture global usability perceptions and the User Experience Questionnaire (UEQ) to assess six dimensions of user experience. The SUS results indicate a mean score of 76.06, which falls within Grade B and the “Good” category, exceeding the global benchmark. This suggests that the system is generally usable, although certain respondents reported minor challenges requiring further improvement. The UEQ results show that Perspicuity (1.94), Dependability (1.94), and Stimulation (1.93) achieved the “Excellent” category, reflecting clarity, reliability, and engagement. Meanwhile, Attractiveness (1.65), Efficiency (1.58), and Novelty (1.72) were rated “Good,” highlighting positive perceptions but also opportunities for optimization. Overall, the findings demonstrate that SINEMA effectively supports extracurricular management with satisfactory usability and strong user experience. The study contributes novelty by integrating SUS and UEQ for comprehensive evaluation within a higher education extracurricular context. Recommendations include enhancing efficiency and novelty to elevate user satisfaction and system adoption.

Abstract

This article analyzes the validity of realistic mathematics education-based students’ worksheet. The research design used in this article is Research and Development (R&D) with a 4D development model, which is to define, design, development, and disseminate. The research subject involved 23 students from class IV. The analysis process involved three validators that consisted of two expert validators and one validator practitioner. To analyze the feasibility of students’ worksheets based on realistic mathematics education, it was used questionnaire. Based on the validity analysis, based on data instrument tested by expert and practitioner tests either in terms of design or material, it showed that students’ worksheets based on Realistic Mathematics Education were assessed with an average score of 4.3. Thus, it could be concluded that the students’ worksheets based on Realistic Mathematics Education were valid to use in learning.

Abstract

The development of Artificial Intelligence (AI) technology opens up significant opportunities for improving the quality of mathematics learning. However, many high school mathematics teachers are still unfamiliar with the use of AI, particularly the use of the Python programming language as a learning support medium. This community service activity aims to improve the knowledge, understanding, and skills of high school Mathematics MGMP teachers in utilizing Python-based AI technology in the learning process. The implementation method includes a preparatory stage in the form of coordination with partners, observation, and interviews to identify teacher needs, and an implementation stage consisting of two training sessions. The first training phase focused on providing conceptual material regarding AI applications in learning, while the second training phase included practical assistance in creating AI-based learning media using Python. The results of the activity showed an increase in teachers' understanding of AI concepts and practical skills in using Python to develop simple interactive quizzes in mathematics learning. Furthermore, participants demonstrated active and collaborative participation throughout the activity. Thus, this community service activity contributed to improving teachers' technological literacy and encouraging innovation in more interactive mathematics learning. It is recommended that similar activities be carried out continuously with a broader scope of material to optimize the use of AI in learning

Abstract

This study aims to analyse the effect of the fiber weight fraction of oil palm empty bunch fiber (OPEBF) composite with HDPE matix on tensile strength and impact. The composite fabrication process is performed using the hot compression method for 210oC with a weight fraction of 40, 50, and 60% fiber. The results showed that the highest tensile strength of the composite fraction of 40% fiber was 3.461 MPa and its modulus of elasticity was 97.702 MPa, followed by the fraction of 50% fiber with a value of 2.948 MPa, the modulus of elasticity was 88.544 MPa, and the lowest value was in the fraction of 60% fiber with a value of 2.205 MPa, and the modulus of elasticity was 87.622 MPa. Furthermore, the highest effort in the impact test on the weight fraction of 40% fiber is 4,249 Joules and an impact energy value of 8364,744 Joules/mm2, followed by a weight fraction of 50% fiber with an effort value to break the specimen of 3,935 Joules and an impact energy value of 7745,651 Joules/mm2, and the lowest attempt to break the specimen at the weight fraction of 60% fiber has a value of 3,341 Joules and has an impact energy of 6576,934 Joules/mm2.
