Abstract

The purpose of this study was know the influence of using learning model STAD through video in increasing activities and material mastery of students class X SMA 7 Bandar Lampung. The study design was pretest-postest non equivalent. X8 and X9 were samples of this study which was chosen by cluster random sampling. The research data were quantitative which was obtained from the average of pretest and posttest analyzed by using t-test or U test. The qualitative was learning activities which obtained from observation sheet and analyzed by index learning activities. The result showed that learning activities of experiment class increased (71.35%). The average of material mastery of students experiment class higher than control class (experiment=80,49; control=77,93). Thus, the conclusion was learning activities and material mastery of pollution area could be improved by using STAD through video.Tujuan penelitian ini untuk mengetahui pengaruh penggunaan model pembelajaran tipe STAD melalui media video dalam peningkatan aktivitas belajar dan penguasaan materi oleh siswa kelas X SMAN 7 Bandar Lampung.

Abstract

This study aimed to determine the effect of compost dose and watering intervals on the soybean growth. The results of the study are used as source material of Student’s Worksheet (SW). Research factorial arranged in a completely randomized design (CRD) with two factors and four replications. The first factor, compost dose: 2.5; 5; 7.5 tons/ha. The second factor, watering interval: 0.5 L/day, 0.5 L/2 days, and 0.5 L/ 3 days. The parameters measured were the soybean plants growth rate and viability of SW. Data were analyzed and tested range of HSD at 5% level. The results showed that the watering interval of 0.5 L/day significantly affected the soybean plants growth rate during the period 7-14 and 21-28 days after planting while the 0.5 L/3 days significantly in the period 14-21 days after planting. The mean value test of the SW application to students of class XII is 82. Thereby very feasible used as a source of learning.Penelitian ini dimaksudkan untuk mengetahui pengaruh dosis pupuk kompos dan interval penyiraman terhadap  pertumbuhan  kedelai.  Hasil penelitian digunakan sebagai sumber materi penyusunan Lembar Kerja Siswa (LKS).
