Abstract

The research carried out produced Student Worksheets (LKPD) based on the REACT learning strategy on linear inequalities material. The development method used is the Instructional Development Model (MPI) with the steps: identification, development and carrying out formative evaluation and revision. This worksheet is designed by utilizing the REACT (Relating, Experiencing, Applying, Cooperating and Transferring) learning strategy, which aims to stimulate students' interest and involvement and strengthen understanding of the concept of systems of linear inequalities. The evaluation was carried out through validation tests by material experts, media experts and mathematics teachers. The results of the research show that the LKPD developed is suitable for use as mathematics learning material.

Abstract

This research is motivated by the importance of maintaining environmental quality in high-activity public transportation facilities. This study aims to determine the impact of public activities on the environment at Kampung Rambutan Terminal, East Jakarta, focusing primarily on air quality and waste management issues. This study utilizes a qualitative descriptive method through direct field observation techniques and in-depth interviews with terminal managers and workers.The results show that the heavy traffic of motorized vehicles and the ongoing excavation projects around the location cause the air quality around the terminal to fall into the moderate category. Based on IQAir data, the primary pollutant detected is PM2.5 at 27,8 µg/m³. Furthermore, the high activity of passengers and street vendors leads to a significant increase in waste volume, particularly during the peak mudik (exodus) season. Based on interview results, sanitation workers routinely clean the terminal area everyday to maintain environmental cleanliness. This study recommends increasing the frequency of waste collection and planting pollutant-absorbing vegetation.

Abstract

As a strategic public policy, the Free Nutritious Meal program serves as a long-term social investment aimed at enhancing the quality of human resources. This study is directed to examine and map the positive contributions of the MBG initiative to the pillars of health, discipline levels, and academic achievement of students through a literature review method. The article search, utilizing keywords such as "Makan Bergizi Gratis," "Implementasi MBG," and "Dampak MBG," yielded 10 relevant scientific articles, which were subsequently analyzed using thematic analysis techniques. The findings indicate that the MBG program exerts a significant positive impact on various dimensions of student development. In the academic aspect, this program improves students' focus, concentration, motivation, and active learning engagement. Health-wise, MBG contributes to improving nutritional status, which supports children's physical and psychological readiness, whereas, in terms of discipline, this intervention is proven to increase attendance rates while reducing tardiness at school. Overall, it is concluded that the MBG program does not merely function to fulfill essential nutritional intake, but also acts to maximize learning effectiveness and student academic performance across all education levels.
