Badai geomagnetik merupakan gangguan yang terjadi di magnetosfer bumi, akibat adanya aktivitas matahari yang dapat berdampak pada infrastruktur listrik di bumi. Sebagai peringatan dini, Lembaga Penerbangan dan Antariksa Nasional (LAPAN) di Indonesia memiliki kegiatan rutin untuk memprediksi kemungkinan terjadinya badai tersebut dalam rentang waktu 24 jam ke depan. Namun pada tahun 2015, hasil prediksi badai geomagnetik yang dilakukan secara manual oleh LAPAN hanya mendapatkan akurasi sebesar 57.14%. Oleh karena itu, penelitian ini mengusulkan pemanfaatan metode Extreme Learning Machine (ELM) dengan inisiasi bobot dan bias input secara acak sehingga memiliki waktu eksekusi cepat dalam melakukan prediksi badai geomagnetik, yang bertujuan untuk mendapatkan nilai prediksi secara otomatis dengan nilai akurasi yang dapat dijadikan sebagai pendukung keputusan. Data penelitian yang digunakan meliputi data coronal hole, coronal mass ejection, solar wind dan indeks Dst pada tahun 2011 hingga 2016. Hasil penelitian ini menunjukkan algoritma ELM memiliki tingkat akurasi yang lebih besar dalam memprediksi badai geomagnetik tahun 2015, dengan nilai 57.80822%. Meskipun memiliki selisih akurasi yang kecil, namun pemanfaatan ELM ini dapat membantu prediksi badai geomagnetik secara otomatis. Secara umum, algoritma ELM yang dibangun dalam penelitian ini memiliki nilai rata-rata akurasi prediksi tertinggi sebesar 69.9055%.

This research focuses on the early development of GEMAS (Game for Microscopic Atom Simulation) as an innovative digital teaching tool designed to support instruction on phase structures in physics education. In response to the post-pandemic shift towards technology-enhanced teaching, GEMAS was developed to integrate interactive, simulation-based pedagogy that enhances conceptual visualization. The study follows the 3D model (Define, Design, and Develop) and employs Multifaceted Rasch Measurement (MRFM) for evaluation. Validation was conducted by five experts, assessing curriculum alignment, scientific accuracy, language clarity, visual arrangement, and instructional effectiveness. These dimensions align with best practices in e-teaching, ensuring accessibility, engagement, and pedagogical rigor. MRFM analysis confirms the tool’s validity, with positive average scores across all indicators. The findings suggest that GEMAS is a well-designed digital resource, ready for implementation to enhance physics instruction in post-pandemic educational settings. The implications of this study extend beyond validating GEMAS as a tool; it demonstrates how immersive 3D simulations can address persistent misconceptions in physics education, particularly in post-pandemic contexts where digital engagement is critical. By bridging abstract concepts with interactive visualization, GEMAS offers a scalable model for enhancing e-teaching practices and fostering deeper conceptual understanding among students.

The rapid growth of retail big data has intensified the challenge of selecting a database architecture that can balance analytical performance and resource efficiency, particularly in data-intensive retail environments. This study aims to conduct a comparative performance analysis between PostgreSQL 16 and MongoDB 8.0 in the context of implementing big data analytics in the retail industry. An experimental quantitative approach is used, utilizing a large-scale, real-world retail sales and inventory dataset to benchmark PostgreSQL 16 and MongoDB 8.0 across a range of representative analytical workloads. Results show MongoDB is 28-31% faster in query processing, but PostgreSQL is 13-17% more efficient in resource usage (CPU, RAM, Storage I/O) and requires 6x less storage. These results indicate that MongoDB consistently achieves faster execution times for read-intensive analytical queries, especially in large-scale aggregation operations. Conversely, PostgreSQL exhibits superior storage efficiency and lower computational resource consumption due to its normalized relational architecture. These findings reveal a fundamental trade-off between analytical speed and infrastructure efficiency in retail big data systems. This research contributes to the development of hybrid data architecture strategies for big data analytics in the retail industry, supporting performance optimization and informed decision-making in data-rich environments

This study intends to analyze the use of presentation-based poetry teaching material design based on the concepts of Cognitive Load Theory (CLT) for Indonesian language instructors in junior high schools in Bandung and Cimahi. In teaching poetry as a complicated literary text, the cognitive load must be carefully managed so that the process of comprehension does not surpass the capacity of students. The research was conducted by using a survey, descriptive-evaluative approach, involving 69 Indonesian language teachers at junior high schools in Bandung and Cimahi. The tools were built in accordance with the three dimensions of CLT: management of intrinsic load, reduction of extraneous load, and optimization of germane load. The data were analyzed descriptively to show the patterns of instructional material design and their conformance to CLT principles. The study found that the use of PowerPoint and Canva is very much present in poetry learning. However, the design still does not entirely comply with the principles of CLT. The presenting materials in the learning process are not yet fully organized considering the effectiveness of material distribution. High text density and non-instructional graphic elements can lead to an increase in unnecessary load. Some of the presentation materials include reflection tasks that might help alleviate cognitive load. The results suggest that the instructional design quality of the poetry teaching materials is not fully consistent with the concepts of Cognitive Load Theory (CLT). The present instructional materials, although not entirely consistent with the principles of CLT, offer significant potential for further growth by including media based on digital technology. Studi ini bertujuan untuk meneliti penerapan desain bahan ajar puisi berbasis presentasi berdasarkan prinsip-prinsip Teori Beban Kognitif (CLT) bagi guru bahasa Indonesia di sekolah menengah pertama di Kota Bandung dan Kota Cimahi. Pengajaran puisi sebagai teks sastra yang kompleks perlu melibatkan pengelolaan beban kognitif secara hati-hati agar proses pemahaman tidak melebihi kemampuan siswa. Studi ini adalah penelitian survei dengan metodologi deskriptif-evaluatif, yang dilakukan pada 69 guru bahasa Indonesia di sekolah menengah pertama di kota Bandung dan Cimahi. Alat-alat tersebut dirancang berdasarkan tiga dimensi CLT, yaitu manajemen beban intrinsik, pengurangan beban ekstrinsik, dan optimalisasi beban germane. Data dievaluasi secara deskriptif untuk mengungkap pola desain bahan ajar dan kesesuaiannya dengan prinsip-prinsip CLT. Temuan studi menunjukkan bahwa penggunaan Powerpoint dan Canva cukup menonjol dalam pembelajaran puisi. Akan tetapi desainnya masih belum sepenuhnya sesuai dengan prinsip-prinsip CLT. Bahan presentasi materi dalam pembelajaran belum sepenuhnya disusun secara baik dengan mempertimbangkan efektivitas penyampaian materi. Terdapat banyak kepadatan teks dan fitur grafis non-instruksional yang dapat menyebabkan peningkatan beban berlebih. Pada beberapa bahan presentasi terdapat kegiatan reflektif dapat mengurangi beban kognitif. Hasil ini menunjukkan bahwa kualitas desain instruksional bahan ajar puisi belum sepenuhnya sesuai dengan prinsip Cognitive Load Theory (CLT). Meski belum sepenuhnya sesuai dengan prinsip CLT, bahan ajar yang ada memiliki potensi yang besar untuk dikembangkan lagi dengan melibatkan media-media berbasis teknologi digital.
