Abstract

This study aims to develop an interactive digital learning media called Fluistik Zone on static fluid material using the 4D development model (Define, Design, Develop, Disseminate). This media covers the subtopic of introductory static fluids, consisting of density, hydrostatic pressure, Pascal's law, and Archimedes' law. The development procedure begins with a needs analysis through teacher interviews and literature reviews, followed by the initial design of Android application-based media equipped with features such as learning videos, interactive quizzes, and Online Active Learning Guide (OALG). Validation was carried out by material experts and media experts with average validity results of 94% and 99% respectively in the very valid category. The practicality assessment by teachers reached 94% in the very well category and student responses showed an average of 85% in the well category. These findings indicate that Fluistik Zone is valid, practical, and interesting for students in supporting physics learning interactively and contextually. This media is designed following the principles of multimedia learning to increase student engagement and understanding. Therefore, Fluistik Zone has the potential as an effective, interesting, and relevant physics learning media innovation to support 21st century learning. However, testing the effectiveness of the media on learning outcomes has not been carried out experimentally and the trial is still limited to one school. Further research is recommended to test the effect of using Fluistik Zone on student learning outcomes through a quasi-experimental design and expand the development to other physics topics and different levels of education.

Abstract

This research investigates the impact of peer interaction and practice frequency on the English vocabulary mastery of eighth-grade students at MTs Miftahul Ulum Kebun Wangi. Employing a quantitative correlational approach, the study involved 48 participants selected through simple random sampling. Data were collected using two instruments: a Likert-scale questionnaire measuring peer interaction and practice frequency, and a 30-item vocabulary test assessing students’ lexical knowledge. The results of the descriptive analysis indicated mean scores of 3.40 (SD = 0.61) for peer interaction, 3.15 (SD = 0.68) for practice frequency, and 72.7% (SD = 11.9) for vocabulary mastery. Correlation analysis revealed a significant positive relationship between peer interaction and vocabulary mastery (r = 0.52, p < 0.001), as well as between practice frequency and vocabulary mastery (r = 0.60, p < 0.001). Furthermore, multiple regression analysis showed that both independent variables jointly accounted for 46% of the variance in vocabulary mastery (R² = 0.46, F(2,45) = 19.1, p < 0.001), with standardized beta coefficients of 0.34 for peer interaction and 0.41 for practice frequency. The findings highlight that collaborative peer engagement and consistent practice significantly enhance students’ vocabulary acquisition. It is therefore recommended that English teachers integrate peer-based and practice-oriented strategies to strengthen students’ lexical development.

Abstract

The fertilizer industry plays a strategic role in supporting agricultural productivity and national food security. However, production effectiveness is often constrained by machine downtime, which negatively affects operational performance. This study aims to analyze the main causes of machine downtime in the NPK granular compaction production process at PT XYZ and to propose appropriate improvement strategies. The research method employs downtime analysis using a Pareto diagram to identify the machine contributing the highest downtime, followed by root cause analysis using a Fishbone (Ishikawa) diagram and the 5W+1H method. The Pareto analysis results indicate that the Compact machine was the largest contributor to downtime during the October 2025 period, with a total duration of 395.23 hours. Fishbone analysis reveals that downtime is influenced by multiple interrelated factors, including machine, method, manpower, material, measurement, and working environment. Furthermore, the 5W+1H analysis shows that failures of key components such as the roller press, crusher chain, bearings, screen, and Teflon were caused by high workload, inadequate maintenance practices, non-compliance with standard operating procedures, substandard spare part quality, incomplete downtime records, and unfavorable working conditions. Based on the findings, strengthening the implementation of preventive maintenance is recommended as the primary strategy to reduce downtime, improve machine productivity, and enhance the overall efficiency of the NPK granular compaction production process.
