Abstract

Mangrove in Tarakan coast encounter various underlined threat named pollution, habitat destruction, and the swelling of human population impending the existence of Molluscan communities. Molluscan is an essential component of Mangrove ecosystem since it could be as predator, herbivore, detritivore, and biofilter as well. However, there only minimum study found investigate the impact of Mangrove. This study, which was conducted from March to August 2023 in five mangrove regions of Tarakan Island, uncovered the distribution of 54 molluscan species, of which 46 were gastropods and 8 were bivalves. This study has identified a remarkable number of species, among the greatest among mangrove ecosystems in Indonesia. Additionally, this study provides an initial account of the distribution of gastropods in the mangrove region of Tarakan Island. The region north of Tarakan Island known as the Juwata mangrove forest harbors the greatest variety of molluscan. A comprehensive documentation of the molluscan species diversity in the mangrove ecosystem adjacent to Tarakan Island's coast has been compiled in order to furnish conservation management with fundamental data that is practical and beneficial.

Abstract

Perubahan ekositem menjadi ancaman bagi kehidupan udang dikawasasan aliran sungai gunung selatan. Meskipun telah dilakukan berbagai penelitian, informasi mengenai morfometrik M. scabriculum penting dilakukan untuk mengetahui perbedaan antar spesies di daerah aliran Sungai Gunung Selatan. Penelitian ini bertujuan untuk menganalisi morfometrik M. scabriculum dikawasan aliran sungai gunung selatan.  Pengambilan sampel di tiga lokasi yang berbeda dan melakukan pengukuran morfometrik, termasuk panjang total, panjang sefalotoraks, dan berat badan. Analisis pengukuran terdiri dari nilai rata-rata, rentang dan standar deviasi (±SE) dari setiap individu. Selanjutnya, hubungan panjang-berat udang dianalisi menggunakan regresi linier. Hasil penelitian menunjukkan bahwa rata-rata panjang keseluruhan jantan dan betina menunjukkan perbedaan yang cukup besar di antara kedua jenis kelamin.  Hasil ini menunjukkan bahwa jantan memiliki ukuran fisik yang lebih besar, yang mungkin meningkatkan keberhasilan reproduksi dan daya saing. Penelitian ini memberikan wawasan yang signifikan untuk pengelolaan dan konservasi sumber daya perairan.

Abstract

Microplastics are particles ≤ 5 mm in size that result from the physical and chemical degradation of polymer-based materials. These particles are ubiquitously distributed in aquatic environments and pose significant threats to aquatic organisms. Currently, microplastic detection predominantly relies on water-sample analyses at a particular point, a method that is inherently limited in spatial coverage. Hydroacoustic techniques offer a promising alternative for detecting microplastics within the water column over larger areas. This study aims to assess the detection of large microplastics (1–5 mm) using a single-beam echosounder (SBES), specifically the Simrad EK-15, under laboratory-controlled conditions. Data validation was performed by comparing acoustic measurements with water-sample analyses using correlation and regression methods. The results reveal high model suitability with coefficients of determination exceeding 0.8 (R² > 0.8) and strong linear correlations (r > 0.8) between the two datasets. Furthermore, the average volume backscattering coefficient (sv) for large microplastics at depths corresponding to 1.5, 1, and 0.5 m were 9.025E-05, 5.403E-05, and 6.850E-05 m²/m³, respectively, while the mean volume backscattering strength (SV) values were -40.445 dB, -42.674 dB, and -41.643 dB at these depths. These findings underscore the efficacy of the SBES in detecting microplastics sized 1–5 mm within the water column and suggest that hydroacoustic methods can serve as a viable approach for expanding microplastic monitoring capabilities.

Abstract

Research that explicitly examines emotional intelligence (EI) in biology learning is still limited, even though extensive evidence shows that EI supports motivation, interaction quality, and learning effectiveness, which are relevant competencies in collaborative tasks and complex biology practicums. This study analyzes research trends and opportunities related to emotional intelligence in biology learning (EIBL) through a bibliometric approach. A literature-based bibliometric analysis was conducted using 339 screened documents retrieved from the ScienceDirect (2015-2024), and the dataset was visualized using VOSviewer to map publication distribution, subject areas, publisher sources, and keyword networks. The findings indicate an increasing number of publications, dominance of empirical studies, and multidisciplinary dissemination across psychology, education, biomedicine, and social sciences. Network visualization identified five thematic clusters (research challenges, methodological approaches, educational contexts, emotional-systemic aspects, and developmental issues) reflecting broader patterns in the dataset rather than trends specific to biology learning. Overall, the dataset suggests emerging opportunities for integrating emotional intelligence into biology learning practices, while highlighting the limited number of studies explicitly situated in biology education and the need for further empirical exploration.Abstrak. Penelitian yang secara eksplisit mengkaji kecerdasan emosional (EI) dalam pembelajaran biologi masih terbatas, meskipun bukti luas menunjukkan bahwa EI mendukung motivasi, kualitas interaksi, dan efektivitas belajar, yaitu kompetensi penting dalam tugas kolaboratif dan praktikum biologi yang kompleks. Penelitian ini menganalisis tren dan peluang penelitian emotional intelligence in biology learning (EIBL) melalui pendekatan bibliometrik. Analisis bibliometrik berbasis literatur dilakukan menggunakan 339 dokumen hasil penyaringan dari ScienceDirect (2015-2024), dan dataset ini divisualisasikan menggunakan VOSviewer untuk memetakan sebaran publikasi, subject area, sumber penerbit, serta jejaring kata kunci. Hasil analisis menunjukkan peningkatan jumlah publikasi, dominasi artikel empiris, dan penyebaran multidisipliner pada bidang psikologi, pendidikan, biomedis, dan ilmu sosial. Visualisasi jaringan mengidentifikasi lima kluster tema (tantangan penelitian, pendekatan metodologis, konteks pendidikan, aspek emosional-sistemik, dan isu perkembangan) yang mencerminkan pola umum dalam dataset, bukan tren spesifik pembelajaran biologi. Secara keseluruhan, dataset menunjukkan peluang berkembangnya integrasi kecerdasan emosional dalam praktik pembelajaran biologi, sekaligus menegaskan terbatasnya studi yang secara eksplisit berada dalam konteks biologi serta kebutuhan eksplorasi empiris lanjutan.
