“…These results indicate that the condition macrozoobentos diversity on Poncan Gadang Island in the moderate category. Moderate diversity indicates that environmental conditions waters are quite supportive for macrozoobentos life and ecosystems seagrass in such locations has sufficient productivity, ecosystem conditions are sufficient balanced and moderate ecological pressure (Herawati et al, 2017;Machrizal et al, 2020;Siahaan et al, 2021;Wijana et al, 2019). The results of the analysis of the dominance index at 5 research stations showed the value of close to 0, this indicates that on Poncan Gadang Island there is no one of the predominate types of macrozobentos (found in numbers a lot).…”

“…Macrozoobentos are communities of organisms that live based on bottom or sediments in an aquatic habitat. They have a relatively fixed and very limited living habitat, therefore they are more susceptible to environmental disturbances such as changes in water quality and sediments, but are very well used as biological indicators determining conditions in the aquatic ecosystem (Bai'un et al, 2021;Saputri et al, 2021;Siahaan et al, 2021). Macrozoobenthos are a group of organisms that are often found alive associated with seagrass beds ecosystem (Machrizal et al, 2019).…”

The seagrass ecosystem of Poncan Gadang island is one of the ecosystems that often come under pressure due to ecotourism activities. Pressure on these ecosystems can have an impact on the diversity of the types of animals that live in them. This research is aimed at knowing the condition of seagrass ecosystems based on the diversity of macrozoobenthos that live in them. The observation point is divided into 5 stations. At each point, a square transect of 1x1 meters is made as many as 10 pieces. Collection of macrozoobenthos samples is carried out by the hand sorting method. The samples collected were then identified at the Ecology Laboratory of the Faculty of Teacher Training and Education, University of Labuhanbatu. Data analysis uses the shannon wienner index (H'), Dominance Index (C') and Similarity Index (IS) formulas. Data analysis was done by computer program Plymouth Routines In Multivariate Ecological Research (Primer) 7th version. The results showed that there were 30 species of macrozobenthos living in the seagrass ecosystem of Poncan Gadang island, with a diversity index (H') of 3.031-3.191, a dominance index (C') of 0.0038 - 0.0053, then a similarity index (IS) of 86.792 – 98.305%. This result indicates the condition of the seagrass beds ecosystem of Poncan Gadang Island is in good condition, with a moderate level of uniformity, low dominance and high similarity

“…Makrozoobentos gastropoda dan bivalvia dominan pada perairan ini (Pramika et al, 2021). Makrozoobentos yang ditemukan di Pantai Gosong, Bengkayang, Kalimantan Barat lebih sedikit, hanya 3 kelas (Bivalvia, Gastropoda dan Holothuroidea) (Siahaan et al, 2021).…”

“…Barus (2004) menyatakan bahwa indeks keanekaragaman menunjukkan jumlah spesies dan persebaran individu. Indeks keanekaragaman makrozoobentos di Pantai Gosong, Bengkayang, Kalimantan Barat adalah 0,72-1,5 dengan kategori rendah hingga sedang (Siahaan et al, 2021). Nilai indeks keanekaragaman sedang, menunjukkan jenis spesies yang beragam dan cenderung labil (Widhiandari et al, 2021).…”

Setapuk Besar adalah salah satu wilayah pesisir yang berada di Kabupaten Singkawang, Kalimantan Barat. Daerah ini memiliki ekowisata mangrove yang berbasis konservasi untuk menjaga kelestarian lingkungan. Luas hutan mangrove Setapuk Besar adalah 26,1 ha. Makrozoobentos adalah salah satu kelompok biota yang hidup di kawasan mangrove. Kepadatan dan keanekaragaman makrozoobentos dapat dijadikan sebagai indikator awal kualitas lingkungan. Oleh karena itu, penelitian ini bertujuan untuk mengetahui kepadatan dan keanekaragaman makrozoobentos di kawasan mangrove Setapuk Besar. Titik penentuan stasiun (Stasiun I dan II) menggunakan metode purposive sampling. Makroozoobentos diambil dari sedimen dengan menggunakan coring berdiameter 2,5 inch dengan panjang 40 cm secara vertikal dan diayak dengan ukuran mesh 0,5 mm. Spesimen diidentifikasi denga mikroskop stereo. Jumlah individu yang diperoleh kemudian dianalisis kepadatan dan keanekaragamannya. Kepadatan tertinggi makrozoobentos adalah Stasiun I dengan 4 kelas, yaitu Gastropoda (1 jenis), kelas Bivalvia (3 jenis), kelas Malascotraca (1 jenis) dan kelas Thecostraca (1 jenis).Indeks keanekaragaman (H’), indeks keseragaman (E), dan indeks dominansi (C) pada Stasiun I adalah 1,5 (keanekaragaman sedang), 0,96 (keseragaman tinggi), dan 0,23 (dominansi rendah), secara berurutan.

This research was conducted in January 2022 in the coastal waters of Tanah Merah Village and at the Marine Biology Laboratory and Marine Chemistry Laboratory, Department of Marine Science, University of Riau. The purpose of the study was to analyze the structure of macrozoobenthos communities in the coastal waters of Tanah Merah Village which includes the type, abundance, diversity, uniformity, dominance index, and similarity of communities. As supporting data in this study, several environmental parameters were also measured which included water quality, sediment type, and sedimentary organic matter content. The research method used is the survey method, where sampling using the squared transect method is carried out at 3 stations. Based on the results of the study found 13 species of macrozoobentos. A species that is found at all stations is Nerita articulate. The abundance of macrozoobenthos is 12,300 ind/ha. The diversity index value (H') of 1.42, indicates a moderate category, namely water quality is still maintained, a uniformity index (E) of 1.66, is classified as a high category, namely water quality is still supportive for macrozoobenthos life, the dominance index (C) 0.17, is included in the low category. In the community similarity index between I and II, 25% of types are not the same, inter-station I and III 43% of types are almost the same, and inter-station II and III 16% of types are not the same. Water quality parameters are as follows: temperature 27-29oC; salinity 30-31 ppt; pH 6-7; DO 3.6-7.6 mg /l. Sedimentary organic matter 4.47-23.53%, muddy sediment type. Based on the value of the aquatic quality biological index at the research site, it is still in good condition
