Abstract

Penelitian ini bertujuan untuk meningkatkan proses pembelajaran dan meningkatkan hasil belajar matematika siswa melalui penerapan model pembelajaran Problem Based Learning. Penelitian ini merupakan Penelitian Tindakan Kelas dengan dua siklus. Dilaksanakan di kelas VIIIB SMP IT Darul Huda Ukui pada semester II tahun ajaran 2020/2021. Subjek penelitian adalah 27 siswa. Instrumen penelitian terdiri dari silabus, RPP, dan LAS, serta instrumen pengumpulan data yaitu lembaran observasi dan tes Ulangan Harian (UH). Berdasarkan hasil analisis diketahui bahwa dalam proses pelaksanaan pembelajaran pada siklus II mengalami peningkatan dari pelaksanaan pembelajaran pada siklus I. Persentase siswa yang mencapai KKM meningkat dari skor sebelum tindakan, skor UH I, dan skor UH II. Jumlah siswa yang mencapai KKM pada skor sebelum tindakan, UH I dan UH II berturut-turut (37,03 %), (48,14%) dan (74,07 %). Hal tersebut mremperlihatkan yakni model Problem Based Learning dapat meningkatkan proses pembelajaran dan hasil belajar matematika pada siswa kelas VIIIB SMP IT Darul Huda Ukui semester II tahun pelajaran 2020/2021.Kata kunci:  Hasil Belajar. Model Problem Based Learning,

Abstract

Siak Regency, Riau Province has a high heterogeneity of vegetation with different types of land. This study aims to determine the types of cerambycid on different types of land in Siak Riau, Indonesia. The method used was Artocarpus trap with collection days consisting of days 4, 7, 10, 13, and 16 after the traps were set up. The collection was carried out on 3 different lands, namely oil palm plantations, rubber and settlements in Buantan Lestari Village, Bungaraya District, Siak Regency, Riau Province. The beetles obtained were then made into an insectarium and identified by looking at the characters on the head, thorax, and abdomen. The results obtained as many as 11 types of cerambycid from 3 subfamilies. The most common types of beetles came from the genus Pterolophia from the Lamiinae subfamily on rubber plantations. Differences in vegetation and habitat conditions affect the number of species and individuals of Cerambycid located on different lands in Siak Regency, Riau Province, Indonesia. Keywords: Land use, longhorns beetle, Cerambycidae, Riau Province, Artocarpus trap
