Abstract

This study addresses the learning challenges faced by children with dyslexia, particularly in writing, spelling, and reading. The objectives are: (1) to analyze user needs and determine suitable application features to support dyslexic children's learning; (2) to design a mobile application, EduLexya, incorporating gamification and interactive card-based multisensory learning methods; and (3) to evaluate the application’s effectiveness in enhancing learning outcomes. Employing a Research and Development (R&D) framework with the Software Development Life Cycle (SDLC) waterfall model, the study involved dyslexic children aged 7–15 years from Somoitan (experimental) and Giriharjo (control) elementary schools. Data collection involved observation, interviews, questionnaires, and pretest-posttest assessments. Statistical analysis included validity, normality, homogeneity, and hypothesis testing via the Independent Samples T-Test. Findings identified essential features—writing, spelling, reading, quizzes, schedules, settings, guides, and feedback. The application was rated highly by material experts (5.00), media experts (4.81), and beta testers (4.81). Posttest results showed a significant improvement in the experimental class (M = 84.37, Sig. 0.000) over the control class (M = 74.33, Sig. 0.043), confirming EduLexya’s effectiveness in improving dyslexic learners’ academic outcomes.

Abstract

Ineffective deployment processes can negatively impact application releases to users, while unstable systems can undermine user experience. This research aims to implement Docker and Kubernetes Pipelines through the DevOps MLOps approach to enhance deployment process effectiveness and analyze the performance of Docker and Kubernetes as alternative environments for deploying the AQG web server. The research methodology follows Research and Development with Development and Operations procedures encompassing planning, coding & building, testing, releasing, deploying & operating, and monitoring. The study focuses on deploy time and web server performance using Docker and Kubernetes Pipelines, assessed through load testing analysis. The subject of this research is the performance outcomes of the web server utilizing Docker and Kubernetes Pipelines. The research outcomes include development of a web server for the Automatic Question Generator service using Docker and Kubernetes Pipelines. Load testing evaluations demonstrate that the web server with Docker and Kubernetes Pipelines exhibits greater stability in error rate, throughput, and response time as threads increase from 5,000 to 10,000. Moreover, the total deploy time decreased from 9 minutes 1 second to 3 minutes 40 seconds, indicating a 245% increase in efficiency

Abstract

Di tengah pentingnya peran website di era saat ini, pembuatan website masih memerlukan waktu, tenaga, dan biaya yang tidak sedikit. Terlebih, pembuatan website juga kurang inklusif bagi mereka yang tidak memiliki pengetahuan dalam pengembangan web. Oleh karena itu, penelitian ini dilaksanakan demi memberikan solusi terhadap permasalahan tersebut melalui IndoWebGen: Language Model (LM) untuk pembuatan website secara otomatis berdasarkan instruksi Bahasa Indonesia melalui metode LoRA. Penelitian ini menggunakan metode R&D dengan mengadopsi model pengembangan CRISP-DM, yang terdiri dari 6 tahap: (1) pemahaman masalah dan tujuan, (2) pengumpulan dan pemahaman data, (3) penyiapan data, (4) pemodelan, (5) penyebarluasan, dan (6) pengujian. IndoWebGen dikembangkan dengan melakukan melakukan proses finetuning melalui metode LoRA pada model basis, Code Llama 7B, dengan menggunakan 500 data sintetis yang di-generate melalui metode self-instruct. IndoWebGen yang telah dikembangkan kemudian diuji kualitasnya melalui human evaluation untuk aspek relevance, usability, dan visual design. Penelitian ini menghasilkan IndoWebGen: LM untuk pembuatan website secara otomatis berdasarkan instruksi Bahasa Indonesia dengan hasil pengujian untuk aspek relevance, usability, dan visual design sebesar 5,933; 5,889; dan 6,089, yang berarti semuanya berkualitas “Baik”. Dengan demikian, IndoWebGen dapat memberikan solusi pembuatan website yang lebih inklusif dan efisien dari segi waktu, tenaga, serta biaya, terutama bagi masyarakat Indonesia.
