Abstract

This study aims to determine the macrozoobenthos in Lake Toba, Toba Samosir Regency. This research was conducted from May to July 2018. Determination of research stations based on environmental baseline consisted of 4 stations, namely station 1 in Lumban Binanga Laguboti village, station 2 in Lumban Bul-bul Balige, station 3 in Lumban Binanga Sigumpar, and station 4 in Hutagaol Sigumpar. Samples were taken using Eckman Grab at 3 times at each station. The macrozoobenthos found consisted of two classes, three orders, eight families, 15 species with a total of 565 individuals. The species found were Brotia subgloriosa, Brotia peninsularis, Brotia castulata, Pomacea diffusa, Pomacea paludosa, Filopaludina polygramma, Filopaludina sp., Melanoides tuberculata, Lymnaea sp., Emilia sp., Corbicula sumatrana, Corbicula fluminea, Corbicula japonica, Pilsbryoconcha exilis, and Anodonta sp.. The macrozoobenthic species with the highest number of individuals was Corbicula sumatrana with 141 individuals and the least was Lymnea sp. by 1 individual. The macrozoobenthos ecological analysis included the average density of 2260, the average diversity index of 1.282, the average uniformity index of 0.633, and the average dominance of 0.390. Then correlated with physico-chemical factors using Pearson correlation (r). Correlation of diversity index with physico-chemical factors from the strongest to the weakest starting from depth and phosphate, turbidity, temperature, pH, BOD, and DO.

Abstract

Zooplankton merupakan organisme air yang memiliki peranan penting dalam rantai makanan. Sei Sikambing merupakan habitat bagi organisme air dan tempat berbagai aktivitas manusia. Tujuan penelitian untuk mengetahui kelimpahan, indeks keanekaragaman, indeks dominansi dan keadaan sifat fisika-kimia di sungai Sei Sikambing Kota Medan, Sumatera Utara. Penelitian ini dilaksanakan pada bulan Maret sampai Mei 2024. Jenis penelitian ini adalah Kausal-Komparatif (Causal Comparative Research) yang bersifat ex post facto yaitu berdasarkan kondisi lingkungan perairan sungai. Keanekaragaman zooplankton di Sei Sikambing terdapat 9 genus yaitu Fritillaria, Lucifer, Dadaya, Cyclops, Pariambus, Lecane, Conochilus, Rotaria, Difflugia dan 1 kelas Crustacea yang merupakan Porcellanida larva. Nilai kelimpahan zooplankton pada stasiun I sebesar 6,9, pada stasiun II sebesar 1,8 dan stasiun III sebesar 0. Nilai indeks keanekaragaman (H’) zooplankton tergolong dalam kategori sedang dengan nilai tertinggi ada pada stasiun I sebesar 1,8. Nilai sifat fisika-kimia tergolong dalam kondisi baik dengan hasil pengukuran suhu air didapatkan nilai sekitar 25°C - 27°C, kecerahan air sekitar 28cm – 35,25cm, pH sekitar 5,81 – 7,41, nilai DO sekitar 4,09mg/l – 5,13mg/l, nilai BOD sekitar 2,6mg/l – 3,1mg/l dan nilai COD sekitar 25mg/l – 7,1mg/l. Kondisi paramater fisika-kimia pada saat penelitian masih mendukung kehidupan plankton. Kualitas air di Sei Sikambing berdasarkan parameter fisika-kimia berada dalam kisaran normal.

Abstract

The research was conducted with the aim of knowing the condition of the phytoplankton community structure based on diversity index criteria in the waters of Lake Toba, Ajibata District, Toba Samosir Regency. This research was conducted in February -March 2021. This type of research was ex post de facto, carried out at 5 observation stations with 3 repetitions. Phytozooplankton samples were taken using Net plankton No. 25. Identification of phytoplankton was carried out in the Biology Laboratory of the Faculty of Mathematics and Natural Sciences, Medan State University. Phytoplankton found in 12 genera, namely: Achnantes, Aulacoisera, Encyonema, Claphora, Stigeoclonium, Dictyosphaerium, Staurastrum, Monoraphidium, Oscillatoria, Microcytis, Nostoc, and Chroococcus. The diversity index at Station I was 1.35, II was 1.36, III was 1.31, IV was 1.36, and V was 1.72. The condition of the phytoplankton community structure is stable in the moderate category. The temperature of the waters ranges from 22°C-25°C, the light transparency to the waters ranges from 4-4.5 m, the pH of the waters ranges from 7.36-8.85, the DO of the waters ranges from 6.84-8.25 mg/l, the BOD of the waters ranged from 1.01 to 3.42 mg/l. Lake Toba water quality based on physical and chemical parameters is within the normal range.
