Abstract

Penelitian ini bertujuan untuk mengetahui perbedaan hasil belajar siswa menggunakan modelpembelajaran kooperatife Student Teams Achievement Division (STAD) dengan Cooperative Integrated Reading andComposition (CIRC) pada materi ekosistem di kelas X SMA Al-hidayah T.P 2015/2016. Populasi dalam penelitian iniadalah seluruh siswa kelas X SMA Al-hidayah Medan yang terdiri dari 3 kelas dengan jumlah siswa seluruhnya 105orang. Sedangkan sampel diambil secara Purposife sampling sebanyak dua kelas yaitu X3 sebagai kelas StudentTeams Achievement Division (STAD) dengan jumlah siswa 36 orang dan kelas X2 sebagai kelas CooperativeIntegrated Reading and Composition (CIRC) dengan jumlah siswa 33 orang sehingga jumlah total sampel dalampenelitian ini sebanyak 69 orang dan jenis penelitian yang dilakukan itu adalah eksperimen. Dari hasil analisis datadiperoleh nilai rata-rata hasil postest pada kelas X3 Student Teams Achievement Division (STAD) sebesar 76,759dengan standar deviasi 11, 62 dan nilai rata-rata postest yang diperoleh pada kelas X2 Cooperative IntegratedReading and Composition (CIRC) sebesar 79,798 dengan standar deviasi 9,50. Dengan demikian hasil belajar siswadengan menggunakan model pembelajaran tipe Cooperative Integrated Reading and Composition (CIRC) lebih baikdari pada model pembelajaran kooperatif tipe Student Teams Achievement Division (STAD). Adanya perbedaanhasil tersebut dibuktikan melalui pengujian hipotesis dengan menggunakan uji-t dan taraf kepercayaan taraf α =0,05, dimana thitung > ttabel (12,60 > 1,998) yang berarti dalam penelitian ini H0 ditolak dan Ha diterima. Sehinggadapat dinyatakan bahwa ada perbedaan yang signifikan secara statistik dimana kelas Cooperative IntegratedReading and Composition (CIRC) lebih baik hasil belajarnya dari pada kelas yang menggunakan Student TeamsAchievement Division (STAD) pada materi ekosistem di kelas X SMA Al-Hidayah T.P 2015/2016.Kata kunci : Kooperatif, Hasil belajar, Ekosistem

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

Research on macrozoobenthic populations in Mariah Bandar Springs, Pematang Bandar District, Simalungun Regency, North Sumatra Province was carried out from May 2022 to June 2022. The purpose of this study was to gather information about macrozoobenthos populations in Mariah Bandar Springs and to find out about the diversity of macrozoobenthos populations in Mariah Bandar Spring Waters. This research was conducted in three locations, namely upstream, middle and downstream of Mariah Bandar Springs. There are each sub-location from each of these locations, in one location consisting of the upper, middle and lower ends. Each of the locations uses three points in macrozoobenthos sampling. Macrozoobenthos sampling using surber net. The results showed that there were 9 species of macrozoobenthos including Lumbricus sp, Thiara winteri, Enallagma nymph, Thiara scraba, Corbicula fluminea, Chironomus sp, Orthetrum glaucum larvae, Hagenius brevistylus and Euplanaria sp. Based on the Shannon-Wienner diversity index, locations I, II, III have low diversity (H' = 0.147).

Abstract

Macrozoobenthos found in the waters of Mariah Bandar Springs, Pematang Bandar District, Simalungun Regency, along with physical and chemical parameters, where biological samples, namely macrozoobenthos, were taken using a quadrant and physical and chemical parameters of the water were taken using a dark colored sample bottle and then analyzed at the BTKL The waters that originate from the Mariah Bandar spring have very clear and shallow water, so that the bottom of the waters (substrate) can be seen directly, which consists of sandy rocks. The macrozoobenthos community in the waters of Mariah Bandar spring consists of four classes, namely Clitellata, Gastropod, Bivalvia, Insecta, and eight families, namely Lumbricidae, Thiaridae, Cyrenidae, Chironomidae, Gomphidae, Paludicola, Coenagrionidae, Libellulidae. The temperature at each observation station ranges from 220C – 350C, brightness ranges from 4 – 4.5 m from the surface, dissolved oxygen (DO) ranges from 6.84-8.25 mg/l, pH ranges from 7.36-8.85 , BOD ranged from 1.01-3.42 mg/l. In general, the physical and chemical parameters measured still support the life of freshwater organisms, unless the pH is classified as acid.

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.
