Abstract

Tidal lake is a coastal lake whose water condition is influenced by the dynamics of tides. This lake serves as a habitat for a diverse array of aquatic biota, including freshwater, brackish, and marine species. This study aims to describe the distribution of larvae, juveniles, crustacea, and adult fish in the context of the coastal lake's role as a nursery and feeding ground. The study was conducted from September 2018 to August 2019, at Lake Siombak, a coastal lake located in the Belawan River estuary along the northern coast of Medan City, Indonesia. Data were collected at high and low tides during the full moon. Larva and juvenile fish? sampling used larval nets with a mesh size of 300 μm and a diameter of 60 cm, while adult fish were caught with gill nets with a mesh size of 1 inch and a dimension of 10 × 2 m. Crustaceans were captured with traps. The research found nine families consisting of six fish families, two crustacean family, and one cnidarian family. The abundance of larvae and juveniles found was 17 to 1797 individuals per 100 m-3. At the high tides, the composition of Ulmaridae (jellyfish: Aurelia aurita) that was caught reached 57.7%. While at low tides, there were more Penaeid families in the Mysis phase, reaching 78.6%. The abundance of Mysis (Penaeid) and jellyfish indicates that the lake serves as a nursery ground for post larvae crustaceans and jellyfish. The presence of adult fish migrating from the sea and Belawan River indicates that the lake functions as a feeding ground in the Belawan estuary.  Therefore, Lake Siombak still plays a crucial role as a nursery and feeding ground for fish, crustaceans, and jellyfish originating from the Belawan River estuary and its surrounding areas. Preserving the sustainability of this lake is crucial to ensuring the continued productivity of fisheries in the Belawan River estuary.

Abstract

Penelitian ini bertujuan untuk menganalisis hubungan antara media pembelajaran, metode pembelajaran, perencanaan pembelajaran, dan gaya belajar siswa dalam meningkatkan efektivitas pembelajaran biologi di SMA Negeri 5 Medan. Metode penelitian yang digunakan adalah mixed methods (metode campuran) yang menggabungkan pendekatan kuantitatif melalui angket dan pendekatan kualitatif melalui wawancara. Hasil penelitian menunjukkan bahwa guru biologi secara rutin menggunakan media pembelajaran, terutama media visual seperti gambar, video, dan animasi yang membantu siswa memahami konsep biologi yang abstrak. Namun, pemanfaatan media interaktif dan audio masih terbatas sehingga belum sepenuhnya mengakomodasi variasi gaya belajar siswa. Selain itu, guru menerapkan metode seperti inquiry learning, discovery learning, dan project based learning yang disesuaikan dengan karakteristik materi dan kebutuhan siswa. Kendala yang dihadapi meliputi keterbatasan kemampuan teknologi dan kurangnya pelatihan media digital. Secara keseluruhan, hasil penelitian ini menegaskan bahwa perpaduan antara perencanaan pembelajaran yang baik, pemilihan metode yang tepat, dan penggunaan media yang variatif dapat meningkatkan keterlibatan serta hasil belajar siswa dalam pembelajaran biologi.

Abstract

This study aims to analyze the development of studies on the integration of ethnoscience into biology learning in high schools during the 2021–2025 period. The method used was a systematic literature review (SLR) by searching articles through Google Scholar using keywords related to ethnoscience and biology education in high schools. A total of 30 articles met the inclusion and exclusion criteria and were analyzed through a process of identifying, reviewing, analyzing, and interpreting data. The results showed that the majority of studies focused on the development of ethnoscience-based learning tools (36.7%) and their implementation in the classroom (33.3%). In the domain of learning outcomes, the greatest improvement occurred in critical thinking skills (33.3%), followed by cognitive skills, scientific literacy, understanding of scientific concepts, and psychomotor skills. The material most frequently associated with local wisdom was biodiversity (29%). These findings confirm that ethnoscience is effective in strengthening conceptual understanding and higher-order thinking skills through a culturally relevant context.

Abstract

Penelitian ini dilakukan untuk menganalisis berbagai kendala yang dihadapi dalam penggunaan media pembelajaran Biologi di SMA Negeri 1 Percut Sei Tuan serta menemukan alternatif solusi untuk meningkatkan mutu proses pembelajaran. Media pembelajaran berfungsi sebagai sarana penting dalam membantu siswa memahami konsep Biologi yang sering kali bersifat abstrak dan sulit dipahami hanya melalui penjelasan verbal. Namun, kenyataannya, masih banyak hambatan yang ditemui seperti keterbatasan fasilitas laboratorium, kurangnya variasi media yang digunakan, serta rendahnya kemampuan guru dalam mengintegrasikan teknologi ke dalam pembelajaran. Penelitian ini menggunakan metode deskriptif kualitatif dengan teknik pengumpulan data melalui observasi, wawancara, dan angket kepada guru serta peserta didik. Hasil temuan menunjukkan bahwa mayoritas guru masih menerapkan metode tradisional seperti penggunaan papan tulis dan buku teks, sedangkan pemanfaatan media berbasis digital seperti video interaktif dan simulasi virtual masih sangat minim. Penyebab utama permasalahan ini antara lain kurangnya sarana teknologi, minimnya pelatihan bagi guru, dan lemahnya dukungan teknis dari pihak sekolah. Solusi yang disarankan meliputi peningkatan kompetensi guru melalui pelatihan media digital, penyediaan fasilitas pembelajaran berbasis teknologi, serta kerja sama antar pendidik dalam mengembangkan media kreatif. Diharapkan langkah-langkah ini mampu menciptakan suasana belajar Biologi yang lebih menarik, interaktif, dan efektif bagi siswa

Abstract

Research of the diversity macrozoobenthos in Batu Bara Regency is crucial to identify the current condition of coastal ecosystems. This information can provide an overview of water quality, resource sustainability status, and serve as a basis for better planning and management of coastal areas. This research is also expected to serve as a reference for developing strategies to mitigate the negative impacts of human activities on coastal ecosystems, ensuring the balance of ecosystems and the preservation of biodiversity. This research will be analyze diversity and abundance (ind/ha) of macrozoobenthos, ecological index data and physical environmental factors and substrate characteristics. The diversity of macrozoobenthos at Sujono Beach, Sejarah Beach, and Kresek Beach consists of three phyla, six classes, and 28 species. The abundance of macrozoobenthos at Sujono Beach is 2459 ind/m3, at Sejarah Beach is 1525 ind/m3, and at Kresek Beach is 1218 ind/m3. The species richness index, diversity index, and evenness index of macrozoobenthos at all three beaches fall into the moderate category, while in the dominance index, none of the beaches have dominating species. The substrate characteristics at Sujono Beach have a sandy clay texture, while at Sejarah Beach and Kresek Beach, they have a dusty clay texture.
