Abstract

Writing hortatory exposition texts poses considerable challenges for EFL students, particularly at the senior high school level. This study aimed to investigate the barriers faced by XI-1 students at SMAN 1 Sidayu in composing hortatory exposition texts and identify the factors influencing their writing performance. Using a descriptive quantitative approach, data were collected through students’ writing tasks and questionnaires administered to 32 participants. The research involved analysing students’ written texts and administering a questionnaire to uncover both internal and external factors. The results revealed that students struggled most with constructing arguments and applying accurate grammar, despite reporting high levels of self-motivation. Furthermore, external support from family, school, and the surrounding environment was perceived as minimal.

Abstract

The rapid adoption of Generative AI as a coding assistant in programming education raises critical pedagogical questions regarding its impact on learning quality. This study investigates whether the use of Generative AI in a deep learning practicum enhances students’ code quality and conceptual understanding or merely improves productivity without meaningful comprehension. A quasi-experimental pretest–posttest control group design was employed involving 60 undergraduate students enrolled in a Deep Learning course. The experimental group (n = 30) used Generative AI tools (ChatGPT/GitHub Copilot) during practicum sessions, while the control group (n = 30) relied on conventional resources. Instruments included a validated conceptual understanding test (α = 0.87) and an analytic code quality rubric based on ISO/IEC 25010 standards (κ = 0.82). Data were analyzed using independent samples t-tests and MANOVA at α = 0.05. Results show that the experimental group achieved significantly higher posttest conceptual scores (M = 78.63) than the control group (M = 72.10), t(58) = 3.34, p = 0.001, d = 0.86. Code quality scores were also significantly higher (20.77 vs. 18.12 out of 25), t(58) = 4.57, p < 0.001, d = 1.18. MANOVA confirmed a significant combined effect (Wilks’ Λ = 0.71, p < 0.001). The study was limited to a single institution and a six-week intervention period, which may restrict generalizability and long-term interpretation. This research provides controlled experimental evidence demonstrating that Generative AI can enhance both technical code quality and conceptual mastery in deep learning education, contributing empirical guidance for responsible AI integration in computing curricula

Abstract

The utilization of solar energy in hydroponic systems offers a potential solution to reduce dependence on conventional electricity and lower operational costs. This study aims to analyze the balance between energy consumption and production in a solar-powered hydroponic farm located in Lenek Daya Village, East Lombok Regency. The system consists of two 80 Wp solar panels, a 4 × 4.2 W water pump, a light sensor, and a 12 V 100 Ah battery for energy storage. The research method includes daily measurement of energy production and consumption over one month, as well as 10-minute interval monitoring for three consecutive days to capture short-term energy dynamics. The results show that daily energy production ranges from 200 to 350 Wh, while energy consumption remains relatively stable between 100 and 200 Wh. The production profile follows a diurnal pattern, with peak power occurring between 11:30 and 14:00. Overall, the solar panels sufficiently meet the system’s energy requirements, even generating a surplus under clear weather conditions. However, weather fluctuations significantly affect daily production, highlighting the important role of energy storage in ensuring continuous operation. This study concludes that the implementation of solar-powered hydroponic systems is feasible and efficient, supporting sustainable agricultural operations in rural areas.
