Abstract

This quantitative correlational study was conducted to find out the relationship between AI-Assisted English Learning, Tech Acceptance, and Willingness to Use English in the AI Learning, with the target population being the graduates of the English Language Education program at UIN Raden Mas Said Surakarta. There were 30 respondents taken for this quantitative correlation analysis, with the respondents completing an online questionnaire designed in relation to the AI usage scale, Tech Acceptance Model, and Willingness to Communicate. The data revealed that both predictors were found to be at high levels, denoting the involvement of the graduates in learning English and their positive attitude towards technology. AI-supported learning in English was revealed to be positively significant with Willingness to Use English (ρ =.386, p =.035), indicating that regular use of AI technologies boosts alumni confidence and drive when speaking English. In contrast, Willingness to Use English did not significantly correlate with Technology Acceptance (ρ =.155, p =.414). Nonetheless, the combination of the two variables explained 23.2% of the variance (R² =.232) and significantly contributed to the variation in Willingness to Use English (F = 4.085, p =.028). This result implied that the integration of AI with English language learning could enhance the quality of graduates’ communication preparedness, especially when they possessed an optimistic attitude towards technology. Future studies involving more factors, such as affective elements, should be conducted to further explore English language usage behavior post-graduation.

Abstract

This paper investigates the optimization of the Global Maximum Power Point (GMPP) and the simulation of Total Harmonic Distortion of Current (THDI) from an inverter connected to a nonlinear load. THDI variations are analyzed with respect to ambient temperature (T) and solar irradiance (G). The study also highlights how harmonic components negatively affect steady-state voltage stability in photovoltaic (PV) systems. The Queen Honey Bee Migration (QHBM) algorithm is applied to optimize GMPP while minimizing THDI. An off-grid PV-inverter system is modeled in MATLAB/Simulink. The model extracts THDI as a function of temperature and irradiance. Simulations cover irradiance from 794.8 to 994.2 W/m² and temperature from 20.0°C to 32.3°C, based on daily measurements from 08:25 to 16:50. The QHBM algorithm tracks GMPP effectively under fluctuating irradiance. Results show a 17.3% improvement in power extraction efficiency and a 32.8% reduction in THDI compared to conventional methods. The highest THDI occurs during low irradiance, particularly in the early morning and late afternoon. The algorithm converges in 0.18 seconds, outperforming other techniques. THDI increases during rapid irradiance and temperature changes. The proposed method ensures stable performance and lower THDI. Combining QHBM with active harmonic filters under low irradiance conditions is recommended to improve power quality and enhance system protection.

Abstract

Background: Reading comprehension represents a crucial aspect of learning English effectively, yet many junior high school students struggle to interpret and engage meaningfully with texts. Purpose: This study examines the impact of the Question Answer Relationships (QAR) strategy on enhancing students’ performance in reading comprehension. Method: This study employed a quantitative one-group pretest–posttest design involving 30 students from an Islamic Public Junior High School (JHS) in Karanganyar, selected through simple random sampling. Pre- and post-tests based on descriptive texts aligned with the national English curriculum were administered, and the data were analyzed using descriptive statistics and a paired-sample t-test to assess changes in students’ reading comprehension. Results and Discussion: The analysis showed that employing the QAR strategy resulted in a notable enhancement of students’ reading comprehension abilities. The average score improved from 22.67 on the pre-test to 32.53 on the post-test. Statistical results from the paired-sample t-test verified a significant improvement (t = –26.191, p < .001), indicating the effectiveness of the intervention. These results suggest that QAR supports students’ understanding of text by helping them differentiate between information derived directly from the text and knowledge constructed from prior understanding, thereby strengthening metacognitive engagement and filling the gap in strategies for fostering comprehension at the junior high level. Conclusions and Implications: The implementation of the QAR strategy provides a learning experience that guides students to think critically, understand the relationship between questions and the text, and gradually enhance their reading comprehension skills. QAR can serve as an innovative instructional approach for English teachers to foster students’ deeper understanding of reading comprehension.

Abstract

Penelitian ini melihat bagaimana pengaruh dua dimensi kualitas layanan—reliabilitas dan interaksi personal—terhadap kepuasan pelanggan, dengan melihat peran citra toko sebagai variabel pemoderasi. Studi dilakukan dengan menyebarkan kuesioner kepada 100 pelanggan Alfamart di Kota Semarang yang dipilih secara purposif. Data kemudian dianalisis menggunakan Structural Equation Modeling (SEM) melalui perangkat lunak SmartPLS 4. Hasil dari penelitian menunjukkan bahwa reliabilitas tidak memberikan pengaruh yang signifikan terhadap tingkat kepuasan pelanggan. Di sisi lain, interaksi personal terbukti memiliki dampak positif dan signifikan dalam meningkatkan kepuasan. Analisis lebih lanjut mengungkap peran kompleks citra toko sebagai moderator. Pada hubungan antara reliabilitas dan kepuasan, citra toko berfungsi sebagai homologiser moderator, yang mengindikasikan bahwa citra toko tidak berinteraksi dengan reliabilitas dan juga tidak memiliki hubungan langsung dengan kepuasan pelanggan. Sementara itu, dalam konteks hubungan interaksi personal dan kepuasan, citra toko bertindak sebagai pure moderator dengan koefisien negatif. Artinya, citra toko justru melemahkan pengaruh positif yang dimiliki interaksi personal terhadap kepuasan pelanggan. Implikasi dari penelitian ini menyoroti pentingnya bagi manajemen ritel untuk lebih memprioritaskan peningkatan kualitas interaksi personal, seperti melalui pelatihan staf yang berkelanjutan. Selain itu, perlu dilakukan evaluasi mendalam terhadap strategi pembentukan citra toko, memastikan bahwa citra yang dibangun tidak hanya kuat, tetapi juga sinergis dan mendukung pengalaman layanan langsung, bukan malah mengurangi efektivitasnya.

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.

Abstract

Bioplastics are biodegradable materials derived from natural polymers such as starch, cellulose, lignin, or chitosan and are considered sustainable alternatives to conventional plastics. In this study, chitosan-based bioplastics were prepared using chitosan extracted from fish scales and reinforced with alkali-treated ramie fibers. Chitosan was dissolved in 1% acetic acid at 50 °C for 4 h, followed by the addition of 5% citric acid and ramie fibers at various contents (15%, 20%, 25%, and 30% relative to chitosan mass), and stirred for an additional hour. The resulting bioplastics were characterized for tensile strength, elastic modulus, water absorption, and surface morphology using SEM. The results indicate that ramie fiber content significantly influences the mechanical and physical properties of the bioplastics. Increasing the fiber content generally enhances tensile strength and reduces water absorption; however, excessive fiber loading can lead to performance deterioration. The optimum formulation was achieved at 25% ramie fiber, exhibiting a tensile strength of 39.60 MPa, an elastic modulus of 43.35 MPa, and a reduction in water absorption of approximately 43% compared to fiber-free bioplastics, along with a more homogeneous surface structure. These findings demonstrate that ramie fiber reinforcement effectively improves the performance of chitosan-based bioplastics.

English vocabulary mastery presents a significant challenge for nonformal education students characterized by heterogeneous backgrounds and limited face-to-face instructional time. This study explores the effectiveness of gamified vocabulary challenges through WhatsApp in improving vocabulary mastery among Grade XI students at PKBM Arrohmah Demak Package C program. Employing a pre-experimental design with one-group pretest-posttest, the research involved 40 students participating in a two-week gamification program with structured daily and weekly tasks. Data were collected through standardized vocabulary tests and participation tracking via WhatsApp platform. Analysis using paired sample t-test and Pearson correlation revealed significant improvement in mean scores from 56.2 to 74.8 with participation rates reaching 87.5%. The multidimensional assessment system measured timeliness, completeness, accuracy, and creativity with an overall achievement of 77.4%. A strong positive correlation was identified between participation levels and learning achievement. Findings confirm that integrating gamification and mobile learning through WhatsApp effectively enhances vocabulary mastery in nonformal education contexts. This platform offers high accessibility and flexibility suitable for adult learner characteristics. Despite its effectiveness, challenges such as limited internet access and low student creativity require attention in future digital learning implementations.
