On-task behavior problems are a common obstacle in the academic activities of school-aged children. Children often experience difficulty maintaining attention, are easily distracted, and exhibit frequent shifts of attention during learning. This has the potential to lead to decreased academic achievement and increased impulsive behavior. This study aims to determine the effectiveness of the shaping behavior modification technique in increasing the duration of on-task behavior. The subject of the study was a 4-year-old boy who exhibited attention problems while working on academic tasks. The research design used a one-group pretest-posttest design with a single-subject approach using an A-B-A data collection model. Data collection was carried out using a duration data sheet to measure the duration of on-task behavior through direct observation. Data analysis was conducted by comparing the average duration of on-task behavior before and after the intervention. The results showed that the shaping technique did not provide a significant increase in the duration of on-task behavior. Although there were fluctuations in the duration of increases and decreases during the intervention phase, these results were not sufficient to prove the effectiveness of shaping in this context. These findings indicate that the shaping approach is less than optimal when applied alone, and that additional intervention methods or other alternatives are needed that are more appropriate to the characteristics and needs of the child. This research provides implications for the importance of selecting appropriate and adaptive behavioral intervention techniques to help children improve focus and engagement in academic activities.
 

The principle of profit sharing based on the concept of risk-sharing offers an alternative approach that is in line with sharia values, in contrast to the conventional interest system. This mechanism is implemented through instruments such as mudharabah and musharakah that support the financing of productive projects. However, its implementation faces challenges related to income fluctuations that can affect the stability of Islamic financial institutions. This research highlights the importance of innovation to increase the effectiveness of sharia monetary policy for inclusive and sustainable economic growth.

This paper discusses the methodologies for balanced transportation problems and their solutions, focusing on efficient and cost-effective distribution of goods from multiple sources to various destinations. The study highlights the importance of maintaining supply and demand balance and explores systematic approaches such as initial solution methods—North-West Corner, Least Cost, and Vogel Approximation Method—and the optimal solution technique, Stepping Stone. An illustrative case involving a company with multiple factories and markets demonstrates the application of these methods, resulting in minimized transportation costs. Additionally, the process of fertilizer allocation and cost analysis is examined, emphasizing the use of the Stepping Stone method to achieve cost minimization. The findings underscore the effectiveness of combining initial heuristics with iterative optimization to attain optimal transportation solutions, thereby enhancing logistical efficiency and reducing operational expenses.

Academic stress is a common challenge experienced by students due to the burden and pressure in higher education environments. This study conducted a systematic literature analysis to evaluate the effectiveness of mindfulness-based psychological interventions and social support in addressing academic stress. By reviewing various empirical studies from leading journals, it was found that mindfulness—through techniques such as Mindfulness-Based Stress Reduction (MBSR)—is beneficial in reducing stress, anxiety, and improving students' emotional regulation and learning focus. In addition, social support from family, friends, and the campus environment acts as a stress buffer by providing emotional support and a sense of connectedness. An approach that combines mindfulness and social support has shown more effective results in helping students manage academic stress. Therefore, it is recommended that higher education institutions develop programs that integrate these two interventions to improve students' mental well-being sustainably.

Home industries such as Noga Sari, daily produce processed nuts with original and chocolate flavors. With previous research that obtained information about the composition of many units of each variant in production, as well as determining the maximum profit obtained optimally, to determine this, as a consequence of the analysis, the maximum profit of UMKM Noga Sari must be calculated. To this end, a linear program is used to calculate the maximum profit using the simplex approach through a solver. The quantitative method is applied in this research. Information gathered from talks with the UMKM Noga Sari's owner.

Consumer behaviour in modern businesses has been greatly altered by technological advancements, leading to the use of digital marketing strategies and social media. These strategies allow businesses to interact with customers, build personalised relationships, and conduct more effective product promotions. Digital marketing and celebrity endorsements are increasingly used in purchasing decisions in Indonesia, especially in the fashion industry. The purpose of this research is to study how celebrity endorsement and digital advertising influence the decision of Surakarta City consumers to buy Erigo products. For this study, quantitative methods were used, data were collected through questionnaires distributed to 150 consumers of Erigo products in Surakarta City. Structural Equation Modeling (SEM) data analysis with the Partial Least Square (PLS) approach was used. The results showed that celebrity endorsement and digital marketing have a significant positive effect on consumer decisions to buy Erigo products in Surakarta city. The limitation of this research is that it is quantitative in nature and does not thoroughly study how consumers perceive the influence of digital marketing and celebrity endorsements culturally and psychologically. This research can provide broader insights into consumer behavior.

This study aims to describe the level of resilience in former drug addicts and analyze its influence on their recovery and social reintegration process. Using a descriptive quantitative approach, data were collected through a questionnaire based on Grotberg’s theory consisting of 48 items. Five participants who had abstained from drugs for approximately two years were involved in this research. The results showed that most participants had high to very high levels of resilience. External factors such as family support and economic conditions, as well as internal factors like self-awareness and future-oriented motivation, significantly contributed to increased resilience. This study emphasizes the crucial role of resilience in helping former drug addicts endure challenging times and prevent relapse.

Public trust in the legal system plays a pivotal role in ensuring the legitimacy and effectiveness of law enforcement in democratic societies. In Indonesia, recurring issues such as judicial inconsistency, law enforcement bias, and unequal access to legal services have contributed to a crisis of confidence among citizens. This study aims to investigate the determinants of public trust in Indonesia’s legal system and to explore the broader social implications through a qualitative case study approach. Data were collected using in-depth interviews with key informants—including legal academics, activists, and citizens—complemented by media content, court rulings, and NGO reports. Thematic analysis, facilitated by ATLAS.ti, revealed three primary dimensions of legal trust: procedural justice, distributive justice, and restorative justice. Key findings show that personal experiences with legal institutions, media portrayal of legal cases, and the quality of institutional communication significantly influence public perceptions of the legal system. Participants who experienced discrimination or unequal treatment expressed higher levels of distrust, while others acknowledged the credibility of institutions such as the Constitutional Court. This study also finds that a lack of proactive and empathetic institutional communication undermines transparency and public legitimacy. The research contributes theoretically by integrating sociological and legal perspectives to understand how legal legitimacy is socially constructed. Practically, the findings highlight the need for structural and communicative reforms to rebuild public confidence in legal institutions. Ultimately, this study argues that trust in the legal system cannot be restored solely through legal formalism, but must also involve participatory engagement and equitable access to justice, especially in the context of Indonesia's evolving socio-political landscape.

This study aims to determine the effect of jumping and throwing park games on improving basic motor skills of junior high school students. The research method used is an experiment with a pretest-posttest control group design. The sample consisted of two classes, each consisting of 30 students, divided into experimental and control groups. The instrument used refers to the Test of Gross Motor Development (TGMD-2) to measure jumping, throwing, and balance abilities. The results of the analysis showed that there was a significant increase in the post-test results of the experimental group compared to the control group (p = 0.000). Jumping and throwing park games have proven effective in integrating locomotor and manipulative movements through a fun play approach, thereby increasing students’ motivation and active participation in physical education learning. These findings indicate that learning media designed according to the characteristics of student development can make a real contribution to improving motor skills. Therefore, the use of this media is recommended as an alternative learning strategy that is educational and fun in the school environment.
