Abstract

Penelitian ini bertujuan untuk untuk mengetahui bagaimana peningkatan motivasi belajar siswa yang diberi kuis dan tidak diberi dalam pembelajaran biologi.  Penelitian yang digunakan adalah penelitian kuantitatif dengan metode eksperimen semu (quasi exsperimen research). Populasi penelitian adalah siswa SMA Negeri 7 Kerinci kelas X yang terdiri dari 5 kelas. Sampel adalah siswa kelas XA dan XB. Teknik pengambilan sampel adalah Random sampling. Hasil penelitian ini adalah motivasi belajar siswa yang diberikan kuis dalam pembelajaran biologi diperoleh motivasi awal (premotivation) dengan kategori rendah dengan skor 58,882 dan motivasi belajar pada kelas eksperimen yang diberikan perlakuan (treatment) dengan pemberian kuis diperoleh peningkatan motivasi belajar dengan kategori tinggi dengan skor 91,25.

Abstract

Black stem potato (Solanum tuberosum L. var. cingkariang/cingkariang potato) are a specific germplasm of West Sumatra with low productivity. One method of propagating this plant is through tissue culture techniques. The addition of Plant Growth Regulator (PGR) determines the results of plant propagation through tissue culture technique. Cytokinins such as 6-Benzylaminopurine (BAP) play a role in cell division and accelerate shoot formation. This study expects to decide the impact of a few convergences of BAP on the shoot enlistment of cingkariang potato. The examination utilized a totally randomized plan (CRD) with four treatments (0, 1, 2, and 3 mg/L BAP) and six replications. The result showed that BAP was able to induce Cingkariang potato shoots in all concentration. BAP 2 mg/L gave the fastest shoot and root emergence time and also gave the highest number of shoots and roots of Cingkariang potato. BAP 2 mg/L was the best concentration for shoot induction of black stem potato (Solanum tuberosum L. var. Cingkariang).
