Abstract

This study aims to assess the diversity, evenness, and dominance of gastropods in dead coral habitats, as well as the current environmental condition of the waters around Lahe Island, Pohuwato Regency. The research was conducted in April 2025. Gastropod sampling was carried out using the hand-picking technique during low tide conditions, employing a belt transect method measuring 50 × 3 meters across three observation stations. Water quality parameters were measured during the early stages of tidal retreat. Based on the results, gastropod species composition consisted of 34 species, 185 individuals, and 12 families (Buccinidae, Columbellidae, Conidae, Cypraeidae, Mitridae, Muricidae, Nassariidae, Pisaniidae, Strombidae, Tegulidae, and Turbinidae). The Shannon diversity index (H’) at all observation stations was < 2, indicating low diversity. The Simpson dominance index (D) at all stations was < 1, suggesting a high level of dominance. The evenness index (Ep) showed values approaching 0, indicating low species evenness. The water conditions around Lahe Island, Pohuwato Regency, indicate a moderate level of pollution based on the Shannon diversity index (H’), yet still support the survival of marine biota.

Abstract

Water quality is very vital to support the survival of organisms. Determination of water quality status needs to be carried out as a reference for monitoring water pollution of an aquatic system. This study aims to assess the status of water quality in the Gorontalo Bay. There are 5 observation stations selected based on the coastal conditions and ecological characteristics. Sampling of water quality parameters was conducted along the Gorontalo Bay in May to July 2017. Sampling procedure based on APHA standard method. The water quality data are analyzed using Pollution Indeks method. Gorontalo Bay has Pollution Index average score of 4.74. This value shows that the quality status of the Gorontalo Bay is considered as polluted category.

Abstract

Penelitian ini bertujuan untuk mengetahui komposisi dan kepadatan sampah pantai di Leato Utara, Kecamatan Dumbo Raya, Kota Gorontalo. Pengambilan sampel dilakukan pada bulan November 2019. Pengamatan dibuat pada 10 transek dengan ukuran transek 5x5m dengan jarak antar transek 20m. Sampah di sortir berdasarkan ukuran makro dan meso kemudian dihitung berat serta jumlah setiap jenis sampah. Hasil penelitian ditemukan 8 jenis sampah yaitu jenis sampah plastik, busa plastik, kain, kaca dan keramik, logam, kertas dan kardus, karet dan kayu. Berdasarkan hasil pengamatan sampah pantai diperoleh sebanyak 126 item dengan berat total 1.332,46g untuk sampah makro dan 1.123 item dengan berat total 1.274,84g untuk sampah meso. Sampah jenis kaca dan keramik merupakan jenis sampah yang memiliki nilai komposisi dan kepadatan tertinggi untuk kedua kategori

Abstract

Rivers play a crucial role as aquatic ecosystems within the hydrological cycle, serving as vital areas for environmental water absorption. Their conditions are intricately shaped by both human activities and the inherent characteristics of their surrounding environments. Among these rivers, the Bone River stands as a pivotal hub of community life in Gorontalo, yet it faces significant vulnerability to pollution. This research endeavors to assess the water quality of the Bone River utilizing Ephemeroptera, Plecoptera, and Trichoptera (EPT) as bioindicators. Conducted between March and April 2021, the study spanned eight carefully selected observation stations, covering the river's course from upstream to downstream. The evaluation of water quality is undertaken through a quantitative analysis of biotile diversity parameters, encompassing calculations of EPT diversity, percentage abundance, and the overall diversity of macrozoobenthos families. From the research findings, it was revealed that the Bone River hosts 16 EPT families, comprising a total of 1438 individual observations. Across the eight stations, the diversity of the EPT family encompassed 16 taxa, inclusive of 7 Ephemeroptera and 9 Trichoptera taxa, with Plecoptera notably absent. Notably, the results of the Biotilik examination yielded a score of 2.28 for the water quality of the Bone River. This score indicates a pollution burden on the river, as evidenced by elevated Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) concentrations at select observation sites, surpassing established quality standards. Furthermore, the absence of macrozoobenthos, particularly Plecoptera, which are known for their sensitivity to pollution, further underscores the compromised state of the river's water quality.
