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

Lymnaea rubiginosa as a snail host found in the Babura River, Medan City, is a type of snail that is known to be an intermediate host in the life cycle of several trematode worms. Lymnaea rubiginosa was collected using net sources at four research stations and there were 10 sub stations at each research station. Research in 2023 found Lymneae rubiginosa in juvenile form and only at station two was it found, and even then only in one collection and only one individual. Snails can be infected by Fasciola gigantica and by other trematodes such as Echinostoma sp. and Trichobilharzia sp. as well as oligochaete worms, namely Chaetogaster sp. Chaetogaster sp. infection in Lymnaea rubiginosa snails originating from rice fields and ponds shows that the spread of these worms is widespread. If it is suspected that the worm is capable of preying on the Fasciola gigantica miracidium, then Chaetogaster sp. more effective for use as a biological control. If the Lymnaea rubiginosa snail has been infected with E. hystricosum, then the snail cannot be infected again with other trematodes such as Trichobilharzia brevis. There seems to be a mechanism that inhibits the occurrence of mixed infections. Trematode and oligochaete worm infections in the snail's body can affect the development and growth of the snail. There is no mixed infection between two types of trematodes, namely Echinostoma sp. and Streigidae in a snail Lymnaea rubiginosa supports the phenomenon of antagonism.
