Abstract

This research aims to develop an interactive learning medium that can enhance students' conceptual understanding of mathematics, specifically in division, through the use of the Fun Math Smart Board. The method used is Research and Development (R&D) which includes the stages of needs analysis, design, development, and product evaluation. The data collection techniques were conducted through pretest, posttest, observation, and interviews with the research subjects being elementary school students selected purposively. The results of the study show that the use of the interactive learning medium Fun Math Smart Board significantly improved students' understanding of division concepts by 87%. This medium facilitates students' comprehension through visualization and interaction. Additionally, its use increases students' interest and participation in the learning process. This study concludes that the Fun Math Smart Board is an effective learning medium for strengthening students' mathematical conceptual understanding, particularly in division. These findings are expected to serve as a reference for teachers in developing innovative and interactive learning media.

Abstract

Urban waste management often faces a gap between technical capacity and field realities. This study aims to describe the waste processing infrastructure at the Cipayung Final Processing Site (TPA) in Depok City, identify non-technical constraints that cause discrepancies between site capacity and waste volume, and analyze the roles and perceptions of stakeholders. A qualitative descriptive approach with a case study design was employed. Data were collected through participatory observation, in-depth interviews with TPA managers, and documentation. Data analysis followed the Miles and Huberman model, with source and technique triangulation to ensure data validity. The results show that the site capacity and infrastructure (excavators and bulldozers) are not proportional to the daily incoming waste volume, primarily due to low levels of waste segregation at the source. The main non-technical constraints include lack of community participation and weak continuous education. Stakeholder perceptions vary, yet all agree on the need for more effective synergy and communication. This study recommends strengthening collaborative governance, enhancing education based on local wisdom, and making technical adjustments to infrastructure according to local waste characteristics.
