This study used a simple pendulum to compare the accuracy and precision of the traditional method and Tracker video analysis in determining the acceleration due to gravity (g). The experiment involved two groups of participants: science teachers in the Philippines, who used the traditional method, and high school students in Uzbekistan, who employed video analysis. Both groups conducted multiple trials by measuring the period of the swinging pendulum. Data were collected by manually recording the pendulum’s motion with a stopwatch or through video analysis software, and the resulting periods were used to calculate g. The data were analyzed by comparing the measured values of g from both methods and assessing the precision and accuracy of each. The results indicated that the traditional method provided more accurate g measurements than the video analysis method, though both methods yielded results close to the accepted average value of 9.81 ms?2. The study suggests that both methods are feasible, but user experience and familiarity with the tools significantly impact the results.

Medical Physics is a branch of physics application that is developing very rapidly. Therefore, the contextualization of Medical Physics is crucial for future physics teachers. This research aims to implement Student-Teacher-Scientist Partnerships (STSP) in Medical Physics and explore students' perceptions of the learning experience through this program. STSP in this research involved prospective physics teachers as students, lecturers in medical physics courses as teachers, and medical physicists as scientists. The benefits of this research are to provide a learning experience of medical physics directly from experts (medical physicists) as a provision for prospective physics teachers to strengthen their knowledge of medical physics content and how to teach it, and to be a recommendation for learning strategies that support contextual physics learning. Implementing STSP in medical physics courses includes planning, implementation, and evaluation activities for one semester of lectures; lectures by the foremost scientists were held in 7 meetings (1 meeting = 2 x 60 minutes). The planning stage includes activities to equalize perceptions between scientists and related lecturers. The course was primarily student-centred, with case study discussions conducted online via Zoom meetings. The scientists were located in East Java Province, Indonesia, while the teachers and students were in East Kalimantan Province, Indonesia. The evaluation stage was carried out by exploring students' perceptions of the program implementation, the results of which can later be used as a reference for the continuation of the program implementation. Results indicated that STSP activities facilitated easier comprehension of medical physics, increased interest in further study, and highlighted connections between course topics and secondary school curriculum.   

Gifted students have varying learning characteristics and learning needs. In this respect, adapted support to their skills and learning characteristics during academic activities plays a key role in engaging in learning activities and achieving learning goals. Accordingly, this study focuses on teachers' support of adaptivity competencies during microteaching from the perspective of both gifted and nongifted students. To this end, a descriptive comparative method was adopted, and gifted (n=124) and non-gifted (n=205) students joined the study. An adapted version of the Questionnaire on Teachers’ Support Adaptivity was employed for collecting data. Data were quantitatively analysed including MANOVA and ANOVA. The results revealed that both groups perceived the support they received from teachers as slightly above and below average, meaning that teachers were not competent. In deep analysis, results indicated a significant difference between the two groups, but no difference between girls and boys. That is, gifted students are more disadvantaged than nongifted students since their teachers lack strategies in adapting their support to meet the different academic needs of their students. This study recommends that teachers need pre-service or in-service training to offer quality and appropriate support for gifted students, which is crucial in achieving learning goals.                                                                                                 

The goal of this community service program is to provide knowledge about the application of restorative justice in the region within the framework of a rule of law, where the criminal justice system in Indonesia is currently still dominated by a retributive approach, which focuses on punishment and revenge against offenders of criminal acts. This approach often receives criticism due to the lack of attention to the recovery of victims and the social reintegration of offenders. This has encouraged the search for alternative resolutions to criminal acts that are more humane and focused on recovery, yet still within a legal framework. One alternative that has gained a lot of attention in recent years is restorative justice (restorative justice). Restorative justice is a problem-solving method through deliberation. This approach emphasizes the restoration of relationships between the offender and the victim, as well as the social reintegration of the offender. Restorative justice views criminal acts as violations of social relationships, rather than merely violations of the law. However, the issues faced by the community regarding the implementation of Restorative Justice in the area are still very unfamiliar, with many people not yet knowing or understanding it. Through this socialization, it was found that the community is capable of understanding the procedures for resolving disputes through community leaders using restorative justice.

This study aims to evaluate the transparency and effectiveness of the use of the 2025 Regional Revenue and Expenditure Budget (APBD) in flood management in DKI Jakarta Province. Although the provincial government has allocated a large budget, the problem of flooding is still an annual issue that has not been resolved. Using a qualitative case study approach and George C. Edward III's policy implementation theory as an analytical tool, this study examines four key variables: communication, resources, implementer disposition, and bureaucratic structure. The results of the study indicate that policy implementation faces various obstacles such as communication with minimal public participation. Limited technical and human resources, implementer caution due to bureaucratic pressure, and weak integration between agencies. This study concludes that the problem of flooding in Jakarta is not only related to technical aspects, but is also a reflection of the suboptimal regional financial governance and sustainable and accountable public policy implementation system.

This study is entitled "The Role of Parboru and Hula-Hula in the Settlement of Divorce Disputes in Batak Toba Customs". The main focus of this study is to analyze the role and position of Parboru (the woman's family) and Hula-Hula (the wife's family) in the divorce settlement process according to Batak Toba customs. This study also presents the dynamics of the interaction of the two elements in customary mediation, as well as how customary values ​​and norms are implemented to maintain the harmony and dignity of the extended family. The method used in this study is a qualitative method with a descriptive approach. Data obtained through interviews and library studies of relevant literature on Batak Toba customary law, Dalihan Na Tolu, and the role of Parboru and Hula-Hula in traditional ceremonies and the resolution of marital conflicts in Batak Toba customs. The results of the study indicate that Hula-Hula has a central position as a decision maker and mediator, while Parboru plays a role as a technical implementer, mediator, and balancer in the customary deliberation forum. The active involvement of both parties is very important to ensure that the divorce process runs according to customary norms and maintains the social harmony of the Batak Toba community. This study is expected to enrich the literature on Batak customary law and become a reference for students, the community, and customary leaders in understanding the importance of the role of kinship in resolving divorce.

This study aims to examine and compare the expenditure and income patterns between traditional market traders in Sukaramai Market and MMTC with street vendors operating around the State University of Medan (UNIMED). This study is based on the main differences between the two groups, especially related to business legality, sales location, and operational costs, which have the potential to affect business effectiveness and the economic welfare of the actors. The comparative quantitative method was used to collect data through questionnaires and Simple Random Sampling sampling techniques on 45 respondents, consisting of 30 market traders and 15 street vendors. The collected data were then analyzed using statistical inference techniques to obtain accurate and reliable parameter estimates. The results of the study show that market traders have an average income of IDR 9.37 million with expenses of IDR 6.7 million per month, so that the net profit obtained reaches IDR 2.67 million. Meanwhile, street vendors have an average income of IDR 7.2 million and expenses of IDR 5.53 million, so that their net profit is around IDR 1.67 million. Although market traders' expenses are higher, they still get a greater net profit. This study confirms that business location, legality, and management system factors significantly affect the efficiency and economic success of traders. This finding is very relevant as a basis for formulating fair and sustainable policies for empowering the informal sector, especially for small and micro traders in urban areas, in order to optimally improve their economic welfare.
