Abstract

Penelitian tentang kajian morfometrik ikan pimpiang di Sungai Kumu Desa Rambah Kecamatan Rambah Hilir Kabupaten Rokan Hulu Provinsi Riau ini telah dilakukan dari bulan November 2018 sampai Januari 2019. Bertujuan untuk mengetahui keragaman jenis ikan dan karakter morfologi dari ikan pimpiang. Penelitian ini menggunakan metode survei dengan teknik pencuplikan sampel secara purposive sampling. Proses pengukuran karakter morfologi ikan pimpiang dengan menggunakan jangka sorong. Penelitian ini menemukan 15 individu ikan pimpiang yang terdiri dari 2 spesies. Berdasarkan penelitian yang telah dilakukan pada tiga stasiun penelitian bahwa rata-rata karakter morfologi Oxygaster anomalura dan Parachela oxygastroides memperlihatkan sedikit variasi. Karakter morfologi Oxygaster anomalura memiliki kisaran panjang total 105,37-164,05 mm dengan rata-rata ± 128,23 mm, dan tinggi badan 15,14-32,89 mm dengan rata-rata ± 22,40 mm. Sedangkan karakter morfologi Parachela oxygastroides memiliki kisaran panjang total 105,27-119,60 mm dengan rata-rata ± 113,14 mm, dan tinggi badan 21,13-24,93 mm dengan rata-rata ± 22,93 mm.

Abstract

This study aimed to test the antioxidant activity of (E)-1-(4-chlorophenyl)-3-p-tolilprop-2-en-1-on (C1) and (E)-1-(4-chlorophenyl)-3- (4-isopropylphenyl)prop-2-en-1-on (C2). This research is useful as a first step in the search for alternative antioxidant compounds and new antibiotics from chalcone compounds. The antioxidant bioactivity test was carried out using the DPPH method. DPPH is a method that is fast, simple, and does not require high costs in determining antioxidant capacity using the free radical 2,2-diphenyl-1-picrylhydrazil (DPPH). This method is often used to test compounds that act as free radical scavengers or hydrogen donors and evaluate their antioxidant activity, as well as quantify the number of antioxidant-radical complexes formed. The antioxidant bioactivity of chalcone compounds (E)-1-(4-chlorophenyl)-3-p-tolilprop-2-en-1-on has an IC50 value of 533.9000 ppm and chalcone compounds (E)-1-(4-chlorophenyl) -3-(4-isopropylphenyl)prop-2-en-1-on has an IC50 value of 718.9054 ppm. The ability of chalcone compounds (E)-1-(4-chlorophenyl)-3-p-tolylprop-2-en-1-one and (E)-1-(4-chlorophenyl)-3-(4-isopropylphenyl)prop- 2-en-1-on is classified as a weak antioxidant [12].

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan model pembelajaran jigsaw disertai media ular tangga terhadap hasil belajar siswa pada materi sistem pernapasan pada manusia di SMP Negeri 5 Rambah Samo. Jenis penelitian yang digunakan adalah quasi experimental dengan rancangan penelitian nonequivalent control group design. Dalam penelitian ini menggunakan teknik total sampling. Sampel pada penelitian ini berupa siswa kelas VIII SMP Negeri 5 Rambah Samo. Instrumen yang digunakan pada analisis ini adalah tes soal pilihan ganda yang berjumlah 25 soal. Dan data menggunakan uji normalitas, uji homogenitas dan uji hipotesis. Hasil penelitian diperoleh rata-rata posttest kelas eksperimen sebesar 76,45 dan kelas kontrol dengan rata-rata 64,17. Berdasarkan hasil penelitian terdapat pengaruh penggunaan model pembelajaran jigsaw disertai media ular tangga terhadap hasil belajar siswa kelas VIII SMP Negeri 5 Rambah Samo pada materi sistem pernapasan pada manusia, 0,00 < 0,05

Abstract

This research aims to determine the Comparison of PBL and PjBL Learning Models on learning outcomes and student learning motivation in the class X virus meteri MAN 1 Rokan hulu TP 2023/2024. Population The study population is all class X students at MAN 1 Rokan Hulu TP 2023/2024 as many as 4 classes with a total of 74 students. Sample taken randomly as many as 2 classes, namely class X3 as a class taught using the Problem Based Learning (PBL) model. using the Problem Based Learning (PBL) model and X2 as a class that is taught using the Projet Based Learning model. which is taught using the Projet Based Learning (PjBL) model, totaling 17 and 19 students respectively. totaling 17 and 19 students. So that the number of samples in this study 36 students. The type of research conducted is Quasi Experiment. The results of the study showed that there was no significant comparison between the application of PBL and PjBL models model on learning outcomes and student learning motivation in virus material class X MAN 1 Rokan Hulu. Both models are equally effective in improving learning outcomes and student motivation.
