Abstract

In recent years, Artificial Intelligence (AI) has created transformative opportunities for educational systems worldwide. AI is no longer viewed merely as a theoretical concept; rather, it has been integrated into various educational applications, including adaptive learning recommendation systems, virtual tutors, learning chatbots, and AI-powered interactive learning media. In 21st-century education, two essential competencies are digital literacy and Higher-Order Thinking Skills (HOTS). Digital literacy refers to the ability to access, evaluate, utilize, and manage information effectively and ethically within digital environments. Meanwhile, HOTS encompasses students’ abilities to analyze, synthesize, evaluate, solve problems, and create, representing cognitive skills that extend beyond basic memorization and comprehension. This study aims to examine the effect of implementing Artificial Intelligence (AI)-based interactive learning media on improving students’ digital literacy and Higher-Order Thinking Skills (HOTS). The study employed a qualitative descriptive approach through a literature review of 40 scientific articles, which were subsequently narrowed down to 13 relevant articles published between 2020 and 2025. The findings reveal that the implementation of AI-based learning media, such as educational chatbots, Gamma App, Canva AI, QuillBot, ChatGPT, PhET Simulation virtual laboratories, and intelligent tutoring systems, has a positive impact on enhancing students’ digital literacy and higher-order thinking skills. The integration of AI in learning encourages students to think critically, creatively, and adaptively in response to ongoing digital technological developments. Furthermore, the study highlights the importance of improving teachers’ competencies, strengthening digital infrastructure, and developing ethical and pedagogical guidelines for the effective use of AI in educational settings.

Abstract

Pemberdayaan masyarakat merupakan pendekatan strategis dalam pembangunan infrastruktur sanitasi dan persampahan yang berkelanjutan, khususnya di wilayah pedesaan. Pelibatan masyarakat dalam proses perencanaan dan pemanfaatan infrastruktur dapat meningkatkan efektivitas program sekaligus memperkuat rasa kepemilikan terhadap fasilitas yang dibangun. Artikel ini bertujuan mengkaji implementasi Pengabdian melalui KKN Tematik Infrastruktur di Desa Poowo, Kecamatan Kabila, Kabupaten Bone Bolango, Provinsi Gorontalo sebagai bentuk intervensi partisipatif untuk memperkuat kapasitas masyarakat dalam perencanaan dan pengelolaan sanitasi serta persampahan. Metode pelaksanaan menggunakan pendekatan partisipatif dan penguatan kapasitas melalui pelatihan, Focus Group Discussion (FGD), survei lapangan, penyusunan peta IMAP (Identifikasi Masalah dan Analisis Potensi), serta penyusunan Rencana Kerja Masyarakat (RKM). Evaluasi dilakukan melalui instrumen kuantitatif dan kualitatif terhadap empat indikator pemberdayaan: kapabilitas, partisipasi aktif, sikap kepemilikan, dan komitmen. Hasil pengabdian menunjukkan peningkatan signifikan pada kapabilitas masyarakat, dengan peningkatan pemahaman konsep sanitasi dan persampahan sebesar 70% setelah pelatihan. Namun, peningkatan kemampuan teknis seperti membaca peta IMAP dan perumusan solusi masih terbatas, masing-masing 27% dan 7%. Partisipasi aktif masyarakat dalam kegiatan hanya mencapai 40%, sedangkan rasa kepemilikan cukup tinggi dengan 80% warga bersedia menjaga infrastruktur meski kontribusi material masih terbatas. Komitmen terhadap perilaku lingkungan juga positif, dengan 73% masyarakat bersedia memilah sampah dan 67% menjaga kebersihan. Temuan ini menunjukkan bahwa pendekatan partisipatif efektif meningkatkan kapasitas pengetahuan dan kesadaran sosial masyarakat. Namun, penguatan literasi teknis dan partisipasi strategis memerlukan pendampingan berkelanjutan serta dukungan kelembagaan untuk memastikan keberlanjutan program infrastruktur sanitasi dan persampahan desa.

Abstract

The waters of Lake Limboto show a decline in water quality, characterized by a decrease in clarity. Environmental factors, such as wind speed and direction, play a significant role in influencing the dynamics and quality of lake waters. To understand the influence of wind on water conditions, a comprehensive hydrodynamic study is required. This study focuses on analyzing the hydrodynamic characteristics of Lake Limboto waters based on momentum flux and its implications for lake water conditions. Wind speed and direction measurements were conducted on seven ducks in Lake Limboto waters during the period of November 1-3, 2024. Data were collected in the morning, afternoon, and evening. The lake's hydrodynamic characteristics were determined using formulas from the measured data. Hydrodynamic characteristics were interpolated using IDW cross validation leave one out and optimized with rank and neighboring point parameters. Wind direction was interpolated using IDW and converted into a vector field using Vector Field Layer Manager. It was found that the momentum flux by wind in Lake Limboto waters has a value range of 0-0.05 N/m2, and cross validation produced an RMSE of 0.003-0.01 N/m2. The interaction of momentum flux from wind and river flow causes sediment to be deposited in the coastal area of ​​Lake Limboto.

Abstract

The demands of 21st-century learning require the integration of digital and interactive media, as conventional science instruction often fails to optimally engage students and improve learning outcomes. The study aims to investigate the impact of using Canva-based video learning media on students' learning outcomes in the topic "Work and Simple Machines" within the science subject. The use of Canva as a learning tool constitutes a 21st-century educational medium that can provide a more efficient learning experience. It is a learning resource that can be edited and customized according to specific needs. This research is based on the fact that the learning process in schools is still dominated by conventional methods such as lectures and discussions, which results in low student activity and learning motivation. The research design is a one-group pretest-posttest design. The sampling technique used in this study is Cluster Random Sampling. The population of this study consists of students from SMP Negeri 1 Marisa, with the sample tested being class VIII A (n = 30), designated as the experimental class. Meanwhile, the research data were collected using test instruments to determine the level of students' learning achievement. The tests used in this study include prerequisite tests (normality test), hypothesis testing, and n-gain analysis. The results of the hypothesis test indicate that the t-value in all sample classes is greater than the t-table value; thus, H₁ is accepted. Based on the n-gain analysis, a value of 0.68 was obtained in the experimental class, which falls into the high category. The statistical test used in the normality test is the Lilliefors test with a significance level set at 5% (α = 0.05). Therefore, the use of Canva-based video learning media has a significant effect on students' learning outcomes in the material on work and simple machines.

Abstract

River sediment is the product of a sedimentation process in the river environment that originates from the weathering of bedrock or erosion processes, organic materials, particles, or anthropogenic substances. Previous research shows the magnetic mineral content in the sediments of the Citarum River and its tributaries. Suspended sediment was collected from the Citarum River and its tributaries in West Java, Indonesia, for mineralogical and granulometric analysis. The aim of this research is to distinguish between magnetic mineral sources, a scanning electron microscope equipped with energy dispersive X-ray spectroscopy (SEM-EDX), and rock magnetism. The hysteresis parameter verifies that the XRD measurement results show that the main magnetic minerals in suspended sediments are ferrimagnetic minerals such as magnetite (Fe3O4). According to the results of the SEM-EDX investigations, the magnetic granules in the Citarum River and its tributaries derive from two distinct sources: pedogenic and anthropogenic. The Citarum River and its tributaries’ magnetic granules are generally octahedral or angular in shape, with broken corners, indicating a pedogenic origin
