Abstract

To determine the composition of macrozoobenthos in the waters of the Babura river. The parameters measured are biological parameters, namely macrozoobenthos composition supported by physical and chemical parameters in the Babura river waters. The parameters measured in this research are biotic parameters, namely the type of macrozoobenthos and abiotic parameters, namely physical and chemical parameters. Physical parameters such as: temperature, turbidity, and chemical parameters such as: pH (degree of acidity), (DO), BOD, COD, and phosphate. Taking macrozoobenthos in shallow water using a quadrant and in deep water using an Eckman grab. Physical/chemical parameters are measured in situ and ex situ. Ex-situ is carried out in the BTKL laboratory. This type of research is ex-post de facto or only reveals existing data. Macrozoobenthos composition found in the Babura river: 1. There are six species of insects, namely Chironomus sp, Aeshna grandis, Dragonfiy nymph macronia, Agrion sp, Damsefly nymph, Dragonfly; 2. There are eight species of gastropods, namely: Thiara winteri, Thiara sp, Melanoides tuberculata, Melanoides rustica, Melanoides gramnifera, Brotia testudinaria, , Planorbis sp, Lymnaea rubiginosa; 3. There are two species of Hirudinea/Clitellata, namely Leeches and Glossiphoniidae; 4 There is one species of trematode, namely Pomatiopsis lapidaria Say; 5. There is one species of crustacean, namely Gammarus sp; 6. There is one species of nematode, namely the rolled worm; 7. There is one species of Oligochaeta, namely Tubifex sp; 8. There are three species of Turbilaria, namely Planaria sp, Dugesia sp, Mesostoma sp, so the macrozoobenthos composition consists of 8 classes with a total of 23 species. Physical/chemical parameters still support macrozoobenthos life in the waters of the Babura river.

Abstract

Gastropod morphometrics in the waters of the Babura River, Medan City, is the title of research carried out to find out how Gastropod morphometrics are useful for knowing growth patterns, eating habits, and also the influence of physical and chemical parameters. So far there has been no research on morphometric measurements of gastropods in the Babura River. Data collection for this research will begin from July 2023 to October 2023. There are three research stations, namely: station 1 on Jalan Bunga Rampai IV Simalingkar B, station 2 on Jalan Karyawisata tip Namurambe, and station 3 in Taman Beringin Medan city with as many repetitions as possible. 3 repetitions, so that the data obtained is more accurate. Gastropods in the Babura river have been identified. Shell morphometric measurements include shell length (A), shell width (B), aperture length (C), number of threads (D). This type of research is ex post de facto. The morphometrics of gastropods found were six species, namely: Filopaludina javanica had an average (mm) for A 18.5, B 13.9, C 3.5; Melanoides tuberculate has a mean for A 21.53, B 8.39, C 6.43, Terebia granifera has a mean for A 18.05, B 7.75, C 4.30, Thiara scraba has a mean for A 19.50, B 15.05, C 16.90, with each number of threads (D) being 4, Lymneae rubiginosa A 6.75, B 2.75, C 3.55, and Dnya 2, Pomaceae canaliculate A 17.00, B 10.85, C 11.48, and D 3. The frequency of presence of each species is Filopaludina javanica 33.33%; Melanoides tuberculate 100%, Terebia granifera has an average of 66.66%, Thiara scraba 66.66%, Lymneae rubiginosa 33.33%, Pomaceae canaliculate 66.66% The results of measuring physical/chemical parameters are generally still below the threshold except for BOD, COD , and ammonia which should be zero. The heavy metals copper (Cu), lead (Pb) and cadmium (Cd) are still far below the threshold.

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.
