Abstract

Penelitian ini bertujuan untuk memperoleh data empiris tentang perbandingan model pembelajaran kontekstual dengan model pembelajaran kooperatif tipe Numbered Head Together (NHT) terhadap hasil belajar siswa kelas X pada materi jamur di SMA Negeri 5 Medan. Tipe penelitian yang digunakan berupa penelitian tindakan kelas. Populasi dalam penelitian ini adalah siswa kelas X SMA Negeri 5 Medan yaitu 8 kelas. Teknik sampling diambil menggunakan metode random sampling pada 2 kelas. Pada kelas eksperimen pertama (X1) diajarkan menggunakan model pembelajaran kontekstual dan kelas eksperimen kedua (X3) menggunakan model pembelajaran kooperatif tipe NHT. Instrumen dalam pengumpulan data menggunakan test (tes hasil belajar). Validasi instrumen posttest diujicobakan pada kelas uji coba. Teknik analisis terkait validasi data diantaranya uji validasi, uji reliabilitas, uji daya beda soal dan uji taraf kesukaran soal untuk memilih pertanyaan yang dianggap baik untuk posttest. Pada kelas eksperimen pertama (X1) diperoleh nilai rata-rata hasil belajar 7,2 dengan variansi 1,358, sedangkan kelas (X3) memperoleh nilai rata-rata hasil belajar 6,2 dengan variansi 1,102. Berdasarkan hasil analisis uji-t diperoleh bahwa ada perbandingan model pembelajaran kontekstual dengan model pembelajaran kooperatif tipe NHT terhadap hasil belajar siswa pada materi jamur kelas X di SMA Negeri 5 Medan.This study aims to obtain empirical data regarding the comparison among contextual learning models and the Numbered Head Together (NHT) type of cooperative learning model on the 1st grade class of learning outcomes on mushroom topics in the High School (on the SMA Negeri 5 Medan). The type of research was used classroom action research. The population in this study was grade first students of High School State 5 Medan, in a total of 8 classes. The sampling technique was taken using the random sampling method from 2 classes. The first-class experimental class (X1) was taught using a contextual learning model and the other class (X3) uses the NHT learning model. The data was collected using a test (test of learning outcomes). The validation instrument was tested out in the experimental class, then analyzed with the validation test, reliability test, discrimination power test and level of difficulty test to select questions that were considered good for the posttest. The first experimental class (X1) showed the average value of learning outcomes obtained was 7.2 with a variance of 1.358, while the (X3) class obtained was an average value of 6.2 with a variance of 1.102. Based on the results of the t-test analysis, it was found that there was a comparison of contextual learning models with NHT type cooperative learning models to student learning outcomes in class X mushroom material at High School (SMA Negeri 5 Medan)

Abstract

The purpose of this study was to classify whether the insects present in the Guava (Psidium guajava L.) plant at the time of fruiting and flowering in Serba Jadi Village, Sunggal District, Deli Serdang Regency, were insect pests, pollinators or just visitors. Sampling was carried out in Serbajadi Village, Sunggal District, Deli Serdang Regency, Sampling, namely by catching insects that perched on guava fruit and flowers (Psidium guajava L) using insect nets (sweep net) and then put them in film bottles. Identification of the caught insects using the book Key Determination of Insects Donald J Borror 1992. The types of insects found on guava (Psidium gujava L) on fruit and flowers in Serbajadi Village, Sunggal District, Deli Serdang Regency are Oxyafusco vittata, Oxyachinensis, Xylocopa aestuans, Orthetrumsabina, Agriocnemis splendidissima, Pelopidas mathias, Bactrocera dorsalis and Drosophila melanogaster.
