Abstract

This research aims to study the utilization of residual stone powder from stone crushers as a substitute for sand in mortar mixtures and to analyze the effect of stone dust variations on the compressive strength characteristics of mortar. The stone powder variations used are 0%, 22%, 26%, 30%, 34%, and 38%, with a total of 72 samples. Compressive strength testing was conducted at 14 and 28 days of age with immersion using PDAM water and swamp water. The results showed that the optimal substitution of stone powder is between 22% - 36%. The highest compressive strength was obtained at a 22% variation with a value of 14.21 MPa (PDAM water) and 13.71 MPa (swamp water). Conversely, the lowest compressive strength was recorded at a 38% variation with a value of 6.15 MPa (PDAM water) and 5.75 MPa (swamp water). Immersion using PDAM water (pH 6.34) produced higher compressive strength values compared to swamp water (pH 4.36), indicating that water pH affects the final results of the mortar. This study recommends the use of stone powder as a sand substitute in mortar production to achieve good quality.

Abstract

Active learning should involve students directly in the learning process through interaction with peers and teachers. However, classroom instruction often fails to engage students effectively, with limited use of varied instructional media and models. This study aims to develop a Respiratory Card learning medium using the Project-Based Learning (PjBL) model to improve learning outcomes of fifth-grade elementary school students on the topic of the human respiratory system. This research employed a Research and Development (R&D) approach using the 4D development model, which includes the stages of Define, Design, Develop, and Disseminate. Data collection techniques included interviews, observations, questionnaires, and tests, while data were analyzed qualitatively and quantitatively. The results showed that: (1) the Respiratory Card learning media was declared valid with average scores of 88% from content experts and 90.6% from media experts, categorized as “highly feasible” using a Likert scale; (2) the media was considered practical based on a 92% average score from teacher responses, categorized as “very practical”; and (3) the media was effective, as indicated by an improvement in students’ test scores to an average of 84.2% at SDS Attaufiq Medan, and significant differences were found in learning outcomes between the experimental and control classes at UPT SDN Percobaan (sig. value = 0.000 < 0.05). The use of the Respiratory Card media enhanced student engagement and improved learning outcomes.
