Inovasi Pembelajaran Berbasis Masalah Berbantuan Media Transvisi untuk Meningkatkan Keterampilan Proses Sains

This study aims to design problem based learning with transvisi media. The learning was applied to improve science process skills at electrolyte-nonelectrolyte material and concepts redox. Quasi experiment design with pretest-posttest control group was used. The differences between pre and post test of Science Process Skill was assumed as effect of treatment. Research subjects were two classgroup of X class in SMA N 1 Randublatung. One class was as control group and the other was as experiment group. They were determined through cluster random sampling. Science process skill was measured by multiple choice test-with reason. Data were analyzed by t-test. Results showed that the implementation of problem based learning at electrolyte-nonelectrolyte and redox can improve students\u27 science process skills, as well as students gave positive responce to learning implementation

The potential of an extract of Zingiber zerumbet (L.) Smith as a feed additive to improve the production performances and meat nutritional composition of broiler chickens

This study aimed at replacing the use of antibiotic growth promoters (AGP) as the feed additive with the Zingiber zerumbet (L.) Smith extract (ZZE) to control Salmonellosis in broiler chickens. This study employed the completely randomized design (CRD), five treatments, namely: T0 (basal diet), T1 (basal diet + S. enteridis infection), T2 (basal diet + S. enteridis infection + 0.33 % ZZE), T3 (basal diet + S. enteridis infection + 0.67 % ZZE), and T4 (basal diet + S. enteridis infection + 1 % ZZE). The addition of the Z. zerumbet extract did not seem to affect the production performances, in which the average feed consumption was 69.38 g ± 4.43 g to 72.71 g ± 4.92 g, body weight gain was 35.67 g ± 1.40 g to 38.30 g ± 3.85 g, feed conversion was 1.89 ± 0.11 to 2.04 ± 0.11, final weight was 1 287.80 g ± 49.97 g up to 1 380.50 g ± 134.90 g, and percentage of carcass was 60.90 % to 68.48 %. However, the use of Z. zerumbet extract with the highest concentration at 1 % decreased the crude fat of meat
