This study aims to analyze the implementation of the Think Pair Share (TPS) learning model in improving problem solving skills in fractional materials for grade V students at SD Negeri 3 Mantingan. The background of this research is the low ability of students to solve fractional problems, mainly due to procedural misconceptions and lack of opportunities to discuss and construct understanding collaboratively. The method used is the Kemmis and McTaggart model Class Action Research (PTK), which consists of four stages: planning, action, observation, and reflection. The research was conducted in one cycle, involving 28 students as subjects. Data collection was carried out through evaluation tests (pre-cycle and cycle I) as well as observation of student learning activities. The results of the study showed a significant increase in problem solving ability. The average score of students increased from 36.43 in the pre-cycle to 93.21 in the first cycle, with a t-test of 25.18 and a p< value of 0.001, indicating a high significance. Learning completeness increased from 0% to 100%. The TPS model has been proven to be able to overcome misconceptions, especially through the peer scaffolding process in the "pair" stage, which helps students in identifying variables and choosing the right calculation operations. In addition, there was an increase in students' collaborative skills in terms of expressing opinions and asking questions, with an achievement range between 68% to 75%. The main obstacles faced in the implementation of polling stations are the management of discussion time and class noise. However, this was successfully overcome through the use of timers and Student Worksheets (LKPD) equipped with scaffolding questions. It can be concluded that the TPS model is an innovative and effective approach in improving mathematical problem solving skills contextually, in line with the principles of the Independent Curriculum.

This study aims to examine the influence of academic stress and self-regulation on academic procrastination among students at SMK Negeri 48 Jakarta. Academic procrastination is a behavior commonly observed among vocational students who are required to balance both theoretical learning and practical skills development. The research employed a quantitative approach using a correlational survey method. A total of 289 students from tenth and eleventh grades, representing six vocational programs, were selected through proportional random sampling. Data were collected through structured questionnaires utilizing a Likert scale and analyzed using multiple linear regression with SPSS version 22. The findings of this study revealed that academic stress has a positive and significant effect on academic procrastination, with a regression coefficient of 0.224 and a t-value of 8.668 (p < 0.05). This indicates that higher levels of academic stress are associated with greater tendencies to procrastinate. In contrast, self-regulation was found to have a negative and significant effect on academic procrastination, with a regression coefficient of -0.351 and a t-value of 7.943 (p < 0.05), suggesting that students with stronger self-regulation skills are less likely to engage in procrastination. Furthermore, the simultaneous influence of academic stress and self-regulation on academic procrastination was significant, as evidenced by an F-value of 64.765 (p < 0.05). The coefficient of determination (R²) was 0.644, indicating that 64.4% of the variance in academic procrastination can be explained by the two independent variables. These results underscore the critical role of stress management and the development of self-regulation abilities in mitigating academic procrastination among vocational school students. Educational interventions focused on reducing stress levels and enhancing self-regulatory behaviors may serve as effective strategies to promote better academic outcomes and reduce counterproductive procrastination habits.

Gross motor development in toddlers (aged 1–3 years) serves as a crucial foundation for their physical, cognitive, and social growth. Parental knowledge about the stages of this development is essential for providing appropriate stimulation and early detection of developmental delays. However, studies indicate that many parents, particularly in developing countries such as Indonesia, still have limited understanding, potentially hindering the optimal development of their children. This study aims to analyze parental knowledge of gross motor development in toddlers through a systematic literature review (SLR) of 20 selected studies conducted between 2020 and 2025. The findings reveal variability in parental knowledge levels, with education, access to digital information, and the role of healthcare professionals identified as key determinants. Recommended interventions include community-based education programs via posyandu (integrated health posts) for rural areas and the use of digital platforms for urban populations, supported by multisectoral policy integration to ensure program effectiveness and sustainability.

After the Dutch colonial occupation, for 78 years Indonesia still used Wetboek van Strafrecht as the law that regulates criminal law until finally in 2023 Indonesia has a National Criminal Code. The National Criminal Code emphasizes the ultimum remedium character by changing fines into one of the main punishments. The formulation of fine as one of the main punishments is part of the effort to overcome the overcapacity in correctional institutions caused by imprisonment which has always been the main choice in the punishment system in Indonesia and is perceived increasingly ineffective. Fines that have been contained in the Criminal Code are also a reference for the determination of fines in special laws outside the Criminal Code, one of which is the Immigration Law which in its application faces many obstacles. This qualitative research uses normative juridical method that analyzes the norms of fine sanctions and its classification in the Indonesian National Criminal Code. Although there are still findings, the fine clause in the National Criminal Code raises new homework for legislators and implementers, related to special laws outside the National Criminal Code that also formulate fines in their criminal sanctions, the research found that the classification of fines in the National Criminal Code is formulated as a new Indonesian punishment policy that has a more ultimum remedium character and prioritizes the principle of justice over legal certainty, can be a guideline for imposing administrative fines for special laws and regulations such as Immigration Law
