Abstract

Infrastructures are increasing as the population grows. The demand for building materials from the construction industry is also improving. Building materials like fine aggregates come from nature, such as sand. This research aims to partially replace natural fine aggregates in concrete mixes using plastic waste combustion residues. This research uses an experimental method with a quantitative approach. The test specimens used in this study were 24 pieces with a replacement percentage of 0, 5, 10, and 20% residue. The results of this study show that the average concrete strength for replacement of 0, 5, 10, and 20% is 23.77; 23.15; 19.47; 17.77 Mpa. At 5% replacement of fine aggregate, the percentage of concrete strength reached 97.4% of normal concretes. It can be concluded that concrete strength affects the partial replacement of fine aggregates with residues from the combustion of plastic and textile waste.

Abstract

This study aims to evaluate the usefulness of a game-based learning tool called the airfield lighting system that uses both VR and AR technology in the classroom. The quantitative research method uses a survey to gather data and test the application in two classes. The application’s usability is represented by data analysis that uses the User Experience Questionnaire (UEQ) model to quantify two aspects: hedonic and pragmatic quality. The study’s findings display the means of the positive value scales, indicating that the pragmatic quality score was 2.538 and the hedonic quality score was 2.548. In addition, To gain a more comprehensive understanding of a product’s quality, we also assess the product’s measured user experience by contrasting it with the outcomes of other well-known products. The results are interpreted within the 10 percent best results range, indicating “excellent” for five instruments and “above average” for novelty instruments. The result presents six instruments of usability level: efficiency, perspicuity, dependability, stimulation, and novelty. This usability test suggests using the airfield lighting system application as the learning medium for student-centered learning.
