Abstract

Pemanfaatan ekosistem lamun menunjukkan bahwa profesi sebagai nelayan merupakan profesi yang diwariskan turun temurun sehingga adanya ketergantungan antara jasa ekosistem lamun dan aktivitas sosial. Tujuan dari penelitian ini adalah untuk mengetahui kondisi ekologi serta jenis biota yang bernilai ekonomi dari hasil tangkapan. Penelitian ini dilaksanaan pada bulan Juli sampai September 2024 bertempat di Desa Torosiaje Laut Kecamatan Popayato Kabupaten Pohuwato. Metode yang digunakan dalam pengambilan sampel lamun dengan metode line transect dengan menggunakan kuadran berukuran 50 x 50 cm dengan jarak antar kuadran lainnya 5 m. Analisis data dalam penelitian ini menggunakan analisis kerapatan dan persen tutupan lamun. Berdasarkan hasil penelitian jenis lamun yang ditemukan di perairan Desa Torosiaje Laut sebanyak empat jenis yaitu jenis lamun Cymodocea rotundata, Halodule uninervis, Thalasia hemprichi, Enhalus acoroides. Kerapatan jenis lamun tertinggi di perairan Desa Torosiaje Laut ialah Enhalus acoroides dengan nilai kerapatan 16.66 ind/m2, sedangkan jenis lamun Halodule uninervis memiliki nilai kerapatan lamun terendah dengan nilai 1,33 ind/m2. Persen tutupan lamun di perairan Desa Torosiaje Laut dalam kategori miskin.

Abstract

Indonesia's marine biological diversity is exceptionally rich, encompassing all existing phyla. Among them, the class Gastropoda represents the largest group within the Phylum Mollusca. Organisms inhabiting hard substrates in intertidal zones exhibit remarkable adaptability to dynamic conditions. Gastropods, in particular, demonstrate a high capacity for adaptation, enabling their survival across various habitats. The level of gastropod species diversity in a given aquatic environment is influenced by several factors, including physical environmental conditions. This study investigates the impact of environmental parameters on the evenness and dominance of gastropods, as well as the effects of environmental changes on these community characteristics. Sampling was conducted at three stations along the coastal area of Bone Bolango Regency. An observational procedure employing a census method was used for sample collection, and purposive sampling determined the sampling points based on specific criteria. Gastropod specimens were collected using a hand-picking technique within a 150 m² transect area, observing the entire station's hard substrate. Water quality data were subsequently analyzed using a pollution index. A total of 422 gastropod individuals were recorded across all stations, representing eight families: Conidae, Cypraeidae, Muricidae, Turbinidae, Neritidae, Strombidae, Tegulidae, and Turbinellidae. Nineteen species were identified from the three research locations. The diversity indices calculated for the three locations are as follows: The Shannon-Wiener diversity index (H′) showed values less than four, indicating moderate diversity. The Simpson's dominance index (D) had values close to one, suggesting a high level of dominance. The Pielou's evenness index (J′) approached one, indicating high evenness within the gastropod community.

Abstract

Gobi merupakan salah satu kelompok ikan yang berperan penting dalam ekosistem perairan dan tersebar luas di berbagai habitat air tawar di wilayah tropis, termasuk di Provinsi Gorontalo. Penelitian ini bertujuan untuk mengetahui nisbah kelamin ikan gobi di Sungai Bone dan Sungai Bolango. Pengambilan sampel dilakukan pada bulan Mei dan Juni 2025 menggunakan alat electrofishing. Identifikasi spesies dilakukan secara morfologis, sedangkan analisis nisbah kelamin ditelusuri melalui anatomi organ reproduksi setelah pembedahan. Uji chi-square dengan tingkat kepercayaan 95% digunakan untuk menentukan keseimbangan nisbah kelamin jantan dan betina. Hasil pengamatan menunjukkan bahwa terdapat 4 spesies ikan gobi di Sungai Bone dan 6 spesies di Sungai Bolango. Sicyopterus longifilis merupakan spesies yang paling banyak ditemukan. Analisis nisbah kelamin menunjukkan bahwa beberapa spesies memiliki rasio jantan dan betina yang tidak seimbang, seperti S. longifilis dan Awaous ocellaris di Sungai Bone serta S. longifilis dan A. grammepomus di Sungai Bolango. Ketidakseimbangan ini kemungkinan dipengaruhi oleh faktor ekologis, biologis, dan antropogenik. Adapun beberapa spesies gobi lain, Belobranchus belobranchus, Belobranchus segura, Sicyopterus parvei yang menunjukkan rasio kelamin seimbang mengindikasikan potensi keberlanjutan reproduksi yang masih baik. Hasil penelitian ini dapat menjadi dasar pendukung dalam pengelolaan dan konservasi ikan gobi secara berkelanjutan di Gorontalo.

Abstract

This study aimed to determine gastropod diversity and the current ecological conditions of the waters in Tilamuta District, Boalemo Regency. Sampling was conducted in April 2025, distributed across three stations. Samples were collected during low tide using a belt transect method covering an area of 150 m2. Identification results revealed a total of 2204 gastropod individuals, representing 12 families: Columbellidae, Cerithiidae, Conidae, Cypraeidae, Strombidae, Littorinidae, Turbinidae, Trochidae, Muricidae, Neritidae, Patellidae, and Vasidae, with a total of 21 species identified. The Shannon Diversity Index (H') indicated a low level of diversity (H' < 2) in the study area. Conversely, the dominance index for the study site ranged from 0.75 to 1.00, signifying a high level of dominance. Furthermore, evenness patterns, as indicated by the J' and Ep indices, all showed values below 1, suggesting an uneven distribution of gastropod species. The study results reveal that the aquatic environment of Tilamuta District, Boalemo Regency, shows signs of pollution, stemming from impaired environmental conditions in the waters, evidenced by low biodiversity.
