Abstract

Bengkayang Regency is one of the potential areas for the development of seaweed cultivation in the waters of Lumukutan Island, seaweed cultivation cages are spread in the waters of Lemukutan Island located in the West Coast area which is very possible for the development of seaweed cultivation of the Euchema cottonii type. This study aims to determine the quality of the aquatic environment for seaweed cultivation, the suitability of water quality for seaweed cultivation Euchema cottonii on Lemukutan Island, Bengkayang Regency. The method used is a survey method consisting of 3 stations. Sampling with a direct measurement stage in the field, sampling was carried out for 3 months as much as 4 times in a period of 10 days, The results of this study The quality of the aquatic environment for seaweed cultivation that is in accordance with the Quality Standards, namely temperature parameters, depth is only found at station one, current speed, salinity, pH and DO, for the suitability of the quality of the aquatic environment of the cages for seaweed cultivation at stations one, two and three criteria are appropriate.

Abstract

Desa Sungai Duri merupakan desa pesisir yang memiliki sungai, oleh sebab itu sebagaian penduduknya berprofesi sebagai nelayan dan pengolah produk perikanan seperti ikan asin dan terasi. Salah satu aliran sungai yang mengalirinya adalah Sungai Duri. Sungai ini digunakan masyarakat untuk kebutuhan sehai-hari, seperti mandi, mencuci, mencari ikan, serta kebutuhan pengairan untuk kebun. Sebagai tempat yang sering digunakan untuk melakukan kegiatan perikanan tangkap, potensi sungai ini cukup tinggi. Hal ini dibuktikan dengan kegiatan memancing yang dilakukan menghasilkan hasil tangkapan berupa ikan dan udang yang cukup melimpah. Tekanan terhadap sungai dirasakan cukup tinggi, oleh sebab itu riset ini bertujuan untuk melakukan identifikasi kelimpahan jenis ikan yang ada di sungai tersebut. Selain kelimpahan jenis, indeks keseragaman, indeks dominansi, serta pengukuran parameter fisika-kimia perairan dilakukan untuk menganalisis kondisi lingkungan perairan di Sungai Duri. Riset dilakukan selama dua bulan, dengan menggunakan alat tangkap gill net, rawai, bubu, pancing, dan jaring serok. Hasil menunjukan bahwa ikan yang tertangkap di Sungai Duri sebanyak 620 individu, dan masuk kedalam 25 famili dan 39 jenis spesies. Jenis ikan yang banyak tertangkap dalam famili Osphrnemidae dan Cyprinidae. Nilai indeks keanekaragaman (H’) tergolong dalam Kategori Sedang, sedangkan indeks keseragaman (E) tergolong dalam Kategori Sedang, dan indeks dominansi (C) tidak ada yang mendominansi di setiap stasiunnya. Kemudian berdasarkan hasil pengukuran kualitas perairan menunjukan bahwa Sungai Duri masih layak untuk kehidupan ikan.

Abstract

Serantangan Lake is a post-mining lake located near an active illegal gold mining area, thus requiring an assessment of its water quality and ecological feasibility. This study aimed to identify the taxa, composition, and density of macrozoobenthos. The research was conducted from December 2024 to February 2025 at three stations using purposive sampling. Samples were collected from 8 sampling points, four times, at two-week intervals. A total of 1,078 individual macrozoobenthos were identified, consisting of 14 genera belonging to 14 families and 9 orders: Mesogastropoda, Architaenioglossa, Decapoda, Haplotaxida, Diptera, Coleoptera, Ephemeroptera, Odonata, and Hemiptera. The highest composition at Stations I and II was dominated by Odonata, while Station III was dominated by Haplotaxida (Tubifex sp.). Station I indicated good water quality, characterized by the presence of intolerant taxa such as Baetidae and Tipulidae. Station II reflected moderate quality, with a dominance of semi-tolerant taxa. Station III showed the lowest quality due to the dominance of tolerant taxa and low diversity. Anthropogenic activities, such as fish harvesting and illegal gold mining (PETI), are suspected to be the main factors affecting the macrozoobenthic community structure in the lake.
