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

The quality of agriculture is affected by insects in agricultural areas. Both insects that have a negative impact such as pests, positive such as predators against pests, and those that are neutral or have no effect on agriculture, but can be an indicator of the ecosystem. Control of plant pest organisms (PPO) is often done by spraying pesticides, but also results in a decrease in the population of insect predators of pests. The diversity of flying insects in Haturak farm, Kupang Village, Tapin Regency has not been documented. This study aims to identify the types of flying insects on Haturak farm and analyze their ecological role. The research method used was a descriptive and observational approach. Data were collected through total roaming and direct documentation using macro photography in the insects’ natural habitat. Analysis was done descriptively and reinforced with literature studies. The results of the study found 18 species of flying insects from six orders. Eight species played a positive role, while ten species had a negative impact on agriculture. Among them, two species played both positive and negative roles, and two others had a neutral role. This condition is less favorable for agriculture because there are fewer predatory insect species than pests. For the sake of biological pest control, enriching pest predator species is recommended to reduce land damage due to high or frequent chemical use. Further studies on diversity and abundance indices are recommended to understand the territorial dominance of each species, as well as to evaluate the effectiveness of biological control. Collaboration between Biology Education and farmers through ecological education builds synergy between science and sustainable farming. The five initiatives enhance ecological literacy and apply local wisdom. To maximize impact, it is recommended to integrate these programs into regular academic and community service activities, ensuring long-term engagement and measurable outcomes.
