Abstract

Developing technology-based teaching materials, such as e-modules, is an effective method for training students' thinking abilities, such as critical thinking and scientific literacy. Objective: This research aims to assess the characteristics, feasibility, and students’ responses to developing an e-module of viral material based on the CIRCSA learning model. Method: The ADDIE development framework, including analysis, design, and development, was used to conduct this research. The scope of this research is limited to assessing the feasibility of the CIRCSA-based e-module characteristics, materials, media, and students’ responses on small-scall trials. Results: Data analysis revealed that the CIRCSA-based e-module that integrates critical thinking and scientific literacy achieved an very valid criterion. The feasibility of materials and media obtained a very valid category. Additionally, students' responses to the e-module usage resulted in a very good category.  Novelty: Developing CIRCSA-based e-modules to improve students' critical thinking and scientific literacy has never been done before.

Abstract

The nozzle is extensively used in many industrial contexts with variable shapes to satisfy particular application requirements, influencing fluid properties. Firefighting sprinkler nozzles have a variety of shapes, leading to research on the possibility of flow treatment devices to improve nozzle performance using numerical analysis. This simulation study examined three different geometry angles of the nozzle (15, 20, and 25 degrees) with different parameters (inlet pressure) and found that the optimal geometry performed the best in terms of pressure retention and velocity output, which are critical for efficient fire suppression operations, with performance varying significantly depending on nozzle angle and applied pressure. A nozzle with a 20-degree angle geometry showed the best performance, with good pressure retention and velocity output, both of which are important for efficient fire suppression. Developing a highly efficient and high-performing nozzle is critical for increasing efficiency and effectiveness in firefighting operations.
