Using Newman's Error Analysis (NEA) as a framework, this study will examine the many ways in which MAN 3 Medan students blunder while answering problems involving logarithms and exponentials. A total of thirty-one MIPA class X students served as subjects for this qualitative descriptive study. Essay tests, interviews with math instructors, and records of student work all contributed to the data set. Data analysis involves reducing, presenting, and making conclusions while triangulating sources to ensure the data is legitimate. According to the research, the two most common points of mistake are when people are trying to grasp the issue and when they are trying to convert it. This is because pupils have a hard time grasping the characteristics and fundamental ideas of logarithms and have a habit of rote memorization rather than critical thinking. Other factors that also affect include the lack of utilization of learning media and low student learning motivation. After being given discussion-based learning and interactive media, the post-test results showed an increase in comprehension and a decrease in conceptual errors. This research recommends that teachers should emphasize student-centered learning by strengthening basic concepts and implementing contextual problem-solving strategies.

This study aims to examine the influence of financial literacy, financial technology, and financial behavior on investment decisions among students at the Universitas Persatuan Guru Republik Indonesia Semarang. The data used in this study is primary data, obtained through the distribution of questionnaires via Google Forms to students at the Universitas Persatuan Guru Republik Indonesia Semarang. The population of this study consists of students from the university, and the sampling technique used is probability sampling with purposive sampling. The sample was determined using the Slovin formula with a margin of error of 10%. The analysis tool used in this study is SPSS 26 to process and analyze the data. This study tests three hypotheses: H1, which states that financial literacy does not significantly affect investment decisions, H2, which states that financial technology does not significantly affect investment decisions, and H3, which states that financial behavior significantly affects investment decisions. The results of the study indicate that H1 is accepted, meaning that financial literacy does not significantly influence investment decisions. On H2, the results also show that financial technology does not significantly affect investment decisions. However, for H3, the results show that financial behavior significantly influences investment decisions. Therefore, it can be concluded that while financial literacy and financial technology do not have a significant impact on students' investment decisions, financial behavior plays a more dominant role in influencing their investment decisions. This study provides valuable insights for universities and other educational institutions to focus more on improving students' financial behavior as a strategic step in enhancing the quality of investment decisions

The purpose of this study is to examine the influence of self-efficacy on students’ interest in continuing their studies to higher education, with achievement motivation as a mediating variable. The research employs a quantitative approach using the survey method. The population in this study consisted of 211 students from SMKN 44 Jakarta. The sampling technique used was proportionate stratified random sampling, calculated using the Slovin formula with a 5% margin of error, resulting in a total sample of 138 students. The data analysis was conducted using Structural Equation Modeling-Partial Least Squares (SEM-PLS) with the assistance of SmartPLS 4.0 software. The analysis process included the evaluation of the measurement model (outer model), the structural model (inner model), and hypothesis testing for direct and indirect effects. The results of the study demonstrate that: (1) self-efficacy has a positive and significant effect on achievement motivation; (2) self-efficacy has a positive and significant effect on students’ interest in continuing their studies to higher education; (3) achievement motivation also has a positive and significant effect on students’ interest in pursuing higher education; and (4) self-efficacy has a significant indirect effect on interest in continuing studies to higher education through achievement motivation as a mediating variable. These findings indicate that both self-efficacy and achievement motivation play important roles in shaping students' educational aspirations beyond secondary school. This study emphasizes the need for educational institutions to strengthen students’ belief in their own abilities and foster achievement motivation to increase their intention to pursue higher education. The findings contribute to the understanding of psychological factors that influence educational planning and can be used as a reference in developing academic guidance programs in vocational high schools.

This study aims to analyze the influence of positive reinforcement and social anxiety on student learning activity in the Department of Office Management and Business Services (MPLB) at SMK Negeri in the South Jakarta area. The background of this research is based on the importance of creating a conducive learning environment through providing positive reinforcement and the importance of understanding the impact of social anxiety on student participation in the learning process. The method used in this study is a survey method with a quantitative approach. The study population consisted of 360 students spread across three schools. The sampling technique used was proportionate stratified random sampling with an error rate of 5%, so that a sample of 190 students was obtained. Data analysis was carried out using the Structural Equation Modeling (SEM) method based on Partial Least Square (PLS) through the SmartPLS 4.0 application. The analysis consists of three main stages, namely measurement model analysis (outer model), structural model analysis (inner model), and hypothesis testing. The results of the study show that positive reinforcement has a positive and significant effect on student learning activity. This means that the higher the application of positive reinforcement, the more active students are in participating in learning activities. On the other hand, social anxiety has a negative and significant influence on student learning activity. This shows that the higher the level of social anxiety experienced by students, the more active they will be in the learning process. These findings affirm the importance of the role of teachers in implementing learning strategies that encourage active student participation and pay attention to students' psychological aspects such as social anxiety in the teaching and learning process.

This study examines the role of Artificial Intelligence (AI) in piano education through a qualitative review of six recent academic sources. AI technology has brought about significant transformations in music learning methods, particularly for the piano instrument. Various AI applications such as automated performance feedback systems, musical accompaniment generators, technical error detection devices, and adaptive learning platforms have enabled new approaches to teaching and learning. AI provides instant feedback, tailored exercises to individual abilities, and creates more interactive and flexible learning environments. These innovations are considered to support the development of students' technical skills more effectively, while increasing learning motivation through personalization and ease of access. Furthermore, this study examines the information systems that support these AI applications, including human-computer interaction, audio signal processing, and the use of machine learning models to recognize playing patterns and technical errors. While AI offers significant benefits, concerns arise regarding its limitations in understanding and responding to the emotional aspects of music. AI is not yet capable of fully supporting the development of subjective and complex musical expression. Over-reliance on this technology is also feared to undermine students' critical thinking, artistic sensitivity, and creativity. Therefore, this study emphasizes the importance of a balanced integration between AI technology and human pedagogical roles, with the teacher remaining the primary facilitator in fostering expression, interpretation, and artistic values in piano learning. The study recommends further research on emotionally responsive AI, blended learning models, and long-term evaluation of AI's impact on students' artistic and musical development.  

The purpose of this study is to describe spelling errors in descriptive texts of grade XI students of SMA Negeri 3 Lhokseumawe. This research method is descriptive qualitative. Data were collected using documentation and note-taking techniques. Data analysis techniques were carried out through several stages, namely collecting data samples and identifying errors, classifying data based on the type of spelling errors, and describing the forms of errors found. The results of the study indicate that many students still make spelling errors, such as errors in capitalization, writing basic words, redundant words, pronouns, prepositions, abbreviations and acronyms, period errors, and comma errors. These errors are caused by students' lack of accuracy and understanding in implementing Indonesian Spelling when writing. In this case, students must be given a better understanding of Indonesian Spelling. To overcome this problem, teachers have an important role in providing more intensive learning related to the implementation of Indonesian Spelling. One effort that can be done is to provide structured writing exercises, accompanied by direct feedback on spelling errors made by students. Furthermore, the use of digital learning media, such as spelling correction apps or interactive writing platforms, can help students improve their writing skills more effectively. With the right learning strategies, it is hoped that students will be able to understand spelling rules in depth and apply them correctly in every writing activity. Furthermore, students' writing skills also need to be honed through more varied activities, such as writing competitions, daily journals, or creative writing projects that require consistent application of spelling rules. Teachers can also implement a peer review method, where students correct each other's writing, thus creating collaborative learning that can increase language awareness.

This study aims to determine the extent to which mental ability influences volleyball underhand passing skills and strategies for improving them in seventh-grade students at MTs SA Atholibiyah Bumijawa. The mental abilities studied included learning motivation, concentration, and self-confidence, as all three are considered important factors in supporting sports performance. The study used an experimental survey method with a correlation approach. The sample was determined through a purposive sampling technique, meaning only students who were actively involved in volleyball learning were included as respondents. The research instruments included a questionnaire to measure students' mental ability levels and an observation sheet to assess underhand passing skill practice. Data analysis was conducted using a correlation test to identify the relationship between mental ability and underhand passing skills, and regression analysis to measure the magnitude of the effect. The results showed a significant effect of mental ability on underhand passing skills. Students with high learning motivation tend to be more enthusiastic and consistent in practicing. Good concentration enables students to control movements, maintain balance, and manage timing when passing. In addition, strong self-confidence encourages students' courage in making decisions and reduces technical errors. This results in passing skills with more accuracy, control, and optimal timing. Improving strategies that can be implemented include structured training with the use of assistive devices to enhance technique, providing motivation and positive feedback from teachers to maintain enthusiasm, and focused training such as game simulations to strengthen concentration. The findings of this study confirm that mental development plays a crucial role in learning sports skills, particularly volleyball, thereby improving both the quality of learning and student achievement.

This community service activity was motivated by the need for an efficient and structured library management system at MI Hidayatul Ulum. Previously, book recording, borrowing, and reporting were done manually, creating administrative challenges and limiting access to information for students and teachers. To address these challenges, the community service team implemented a web-based library information system designed to simplify collection management, facilitate book searches, and expedite the borrowing and return process. The implementation method included partner needs analysis, system design and installation, training for staff and teachers, and evaluation of implementation results. The system was designed to be accessible through the school's local network with a simple and user-friendly interface. Training was provided to ensure the school was able to utilize and manage the system independently. The results showed that the implementation of this information system improved library management efficiency and expanded user access to information. Teachers could more easily monitor book collections, while students found it easier to search for and borrow books. Furthermore, the system accelerated administrative processes and reduced the risk of recording errors. Another positive impact was the growth of a technology-based literacy culture within the madrasah. With the availability of faster book search and borrowing services, students' interest in reading increased. A participatory approach involving schools from the planning stage through evaluation ensures that the resulting solutions meet needs and can be implemented sustainably. This community service activity is expected to serve as a model for implementing simple technology that has a real impact on improving the quality of basic education services.
