Abstract

Chemistry learning at the high school level often presents unique challenges. The subject matter is inherently abstract and difficult to grasp, while limited teaching aids and minimal use of technology further contribute to low student motivation and achievement. Observations at SMA PGRI Kota Pagar Alam revealed that although 85% of students own smartphones, these devices have yet to be fully utilized to support learning.This study focuses on developing an interactive chemistry learning multimedia application using the Multimedia Development Life Cycle (MDLC), which consists of six stages: concept, design, material collecting, assembly, testing, and distribution. The final product integrates animations, simulations, gamebased interactive quizzes, and audio narration into a cohesive learning experience.Expert validation from the fields of media, content, language, and design yielded an average score above 4.5—classified as highly feasible—with visual quality (4.70) and content relevance (4.65) standing out as key strengths. Testing with 30 eleventh-grade students showed a substantial improvement in understanding, with the average score increasing from 58.2 (pretest) to 82.4 (posttest), representing a 41.6% gain. Furthermore, 87% of students reported that the multimedia helped them better comprehend chemistry concepts, while 92% found the interface engaging and interactive.These findings affirm that combining visual, audio, and interactive elements can significantly enhance the effectiveness of chemistry learning. Looking ahead, this multimedia application holds strong potential for broader implementation, including personalized learning content and the incorporation of game elements to create a more immersive experience. With adequate teacher training and proper device availability, this innovation could serve as a sustainable solution to address the challenges of chemistry education in schools.

Abstract

This study presents a comparative evaluation of Ridge Regression, Support Vector Regression (SVR, RBF), and ExtraTrees Regressor against a lag-1 (persistence) baseline for short-term load forecasting (STLF) of IoT smart-home energy consumption at an hourly resolution. The research is motivated by the need for accurate forecasts to enable operational efficiency, peak shaving, and residential demand response. The workflow emphasizes reproducibility: hourly resampling, short-gap imputation, minimalist feature engineering (calendar and lag features), and a time-based split of 70%/15%/15% (train/validation/test). Models are compared using MAE, RMSE, and R², prioritizing RMSE due to its sensitivity to spikes. Results show that on validation ExtraTrees performs best (RMSE 1.012, R² 0.854) and surpasses the lag-1 baseline (RMSE 1.507, R² 0.677). However, on the test set the lag-1 baseline is most accurate (RMSE 1.457, R² 0.808, MAE 0.900), while ExtraTrees is the closest yet does not surpass it (RMSE 1.482, R² 0.802, MAE 1.119). SVR and Ridge degrade markedly on test (RMSE > 2.0; R² < 0.65). These findings highlight the strength of persistence at a one-hour horizon and the need for seasonal/exogenous features and hyperparameter tuning to reduce large errors. Our practical contribution is a concise, Colab-based pipeline. Future work includes walk-forward validation, residual modeling over lag-1, adding daily/weekly lags and weather variables, and significance testing of error differences.

Abstract

The rapid development of digital technology has increased the demand for high-quality user interface (UI) and user experience (UX) design in online services, including the Riau University (UNRI) Digital Library, which has been available since 2016 as an academic resource platform. An evaluation using the User Experience Questionnaire (UEQ) revealed weaknesses in attractiveness and novelty, which reduced user satisfaction. This study aims to redesign the UI/UX of the UNRI Digital Library mobile application by applying the auto layout feature in Figma with the Five Planes framework (strategy, scope, structure, skeleton, surface). The research employed a mixed approach, including literature study, interviews with the library administrator, and UEQ surveys distributed to 100 active students as primary users. The redesigned prototype was evaluated with UEQ, and the results indicated improvement across all dimensions, particularly in attractiveness and novelty, which previously scored negative. The integration of auto layout enhanced design efficiency and consistency. The findings demonstrate that applying the Five Planes method supported by responsive design features can produce a more modern, intuitive, and engaging interface. This study provides practical implications for the development of digital library systems and theoretical contributions to mobile-based UI/UX design research.
