Abstract

The teaching of physics and biology as part of science education in high school should be linked to real-world phenomena and local culture so that students can understand scientific concepts in context. One aspect of Minangkabau culture that has the potential to serve as a learning resource in high school is Silek Kumango, a style of silek originating from Nagari Kumango, Tanah Datar, West Sumatra. This study aims to examine Minangkabau Silek Kumango through an ethoscience approach by identifying the physics and biology concepts present in its movements as a potential learning resource for high school students. The method used is a descriptive qualitative approach based on a literature review. Data were collected from scientific articles, documents, and previous research findings regarding Silek Kumango, ethnoscience, and culture-based science education. The findings indicate that Silek Kumango incorporates physics concepts such as motion, force, equilibrium, impulse, momentum, work, energy, torque, center of mass, and friction. From a biological perspective, Silek Kumango relates to the human musculoskeletal system, muscle function, joints, neural coordination, body balance, reflex responses, respiration, and physical fitness. The integration of Silek Kumango into high school physics and biology instruction can serve as a contextual learning resource for topics such as motion, energy, the human musculoskeletal system, the nervous system, the respiratory system, and the circulatory system. This study demonstrates that local culture functions not only as a cultural heritage but also as a bridge between community knowledge and scientific knowledge in schools.

Abstract

Pemantauan maritim terpadu sangat krusial di tengah ancaman kerusakan ekosistem global akibat eksploitasi perairan secara ilegal. Literatur saat ini masih terfragmentasi pada pembahasan komponen teknologi secara terpisah sehingga menyisakan kesenjangan riset yang nyata dalam pemetaan holistik interaksi lintas disiplin antara domain komputasi, infrastruktur fisik, dan target ekologi dalam satu kerangka kerja fungsi ganda. Penelitian ini bertujuan mengisi celah tersebut dengan memetakan lanskap literatur global terkait penerapan strategi penggunaan ganda sonar pasif untuk deteksi penangkapan ikan ilegal dan pemantauan ekologi maritim. Desain penelitian memadukan analisis bibliometrik kuantitatif dan tinjauan literatur sistematis kualitatif. Sebanyak 217 dokumen final berhasil diekstraksi dari pangkalan data Scopus pada rentang publikasi tahun 2006 hingga 2026 dengan mengikuti protokol penyaringan ketat. Analisis data dieksekusi menggunakan perangkat lunak pemetaan visual untuk mengevaluasi jaringan kemunculan bersama kata kunci dan metrik performa objektif. Hasil analisis mengungkap lonjakan publikasi secara eksponensial semenjak tahun 2019 yang dipelopori oleh Tiongkok pada volume produksi dan Amerika Serikat pada dampak sitasi. Pemetaan topologi jaringan memunculkan tiga klaster tematik utama. Klaster pertama menyoroti integrasi arsitektur kecerdasan buatan untuk otomatisasi pelacakan armada kapal gelap. Klaster kedua berfokus pada peran diagnostik ekoakustik untuk mengukur tingkat stres mamalia laut dan degradasi terumbu karang. Klaster ketiga menegaskan posisi hidrofon resolusi tinggi sebagai fondasi perangkat keras penangkap sinyal presisi. Kesimpulan penelitian ini membuktikan konvergensi antara sensor akustik mutakhir dan algoritma komputasi cerdas sanggup menciptakan sistem pengawasan laut yang akurat dan bersahabat dengan lingkungan. Keberhasilan implementasi berskala global pada masa depan akan sangat bergantung pada optimalisasi komputasi tepi dan kolaborasi pembagian data lintas yurisdiksi perairan.

Abstract

This study aims to determine the effectiveness of a Problem-Based Learning (PBL)-based STEM approach using Assemblr Edu media on students’ creative thinking skills and learning outcomes in the respiratory system curriculum. This study employed a quantitative method with a quasi-experimental design in the form of a nonequivalent control group design. The study sample consisted of class XI-3 as the experimental group and class XI-4 as the control group at State Senior High School 5 Samarinda. Data collection techniques included achievement tests, observations of creative thinking skills, interviews, and documentation. The research instruments comprised pretest and posttest items, as well as an observation sheet for creative thinking skills covering the indicators of fluency, flexibility, originality, and elaboration. Data were analyzed using normality tests, homogeneity tests, N-Gain tests, and hypothesis testing. The results of the study indicate that the implementation of a PBL-based STEM approach supported by Assemblr Edu is effective in improving students’ creative thinking skills and learning outcomes. The improvement in creative thinking skills is evident from the increase in scores on each indicator of student creativity throughout the learning process. Additionally, the learning outcomes of students in the experimental class were higher than those in the control class after the intervention was administered. The use of the Augmented Reality-based Assemblr Edu platform helps students visualize abstract concepts of the respiratory system, making learning more interactive, contextual and meaningful. Thus, a Problem-Based Learning (PBL)-based STEM approach supported by Assemblr Edu can serve as an innovative alternative in biology education to enhance students’ creative thinking skills and learning outcomes.
