Pengaruh Model Think Pair Share Berbantuan Media Poster Materi Klasifikasi Makhluk Hidup

This research aims to find out the effect of poster-aided Think Pair Share learning model on student learning outcomes in the material of Living Organism Classification in the seventh grade of State Junior High School (SMPN) 2 Sungai Raya. The method used was the quasi-experimental design with a non-equivalent control group design. The samples are consisted of two classes, seventh grade class F as the experiment class and class H as the control class, while the sampling technique used was the intact group. The average student outcome in the experiment class was 16,66, while the control class 15,10. The results of the analysis using the U Mann-Whitney test show that Zcount< -Ztable (-2,60 < -1,96), meaning that there were significant differences between the learning outcomes of student taught using the poster-aided Think Pair Share and using the conventional learning model. The size effect value obtained was 0,47 in the category of moderate so that the poster-aided Think Pair Share learning model had an impact of 18,08% on the student learning outcomes in the material of living organism in the seventh grade of SMPN 2 Sungai Raya

Uji Toksisitas Subkronik Kombinasi Ekstrak Daun Uncaria Gambir Dan Caesalpinia Sappan

Hiperuresemia prevalence tends to increase in society. A combined extract of Uncaria gambir (gambir) and Caesalinia sappan (secang), had been proven to reduce blood uric acid level in vivo. This study aimed to evaluate the subchronic toxicity of this combination in male and female Sprague Dawley rat strain. Animals were randomly grouped into four groups, namely, DOSE-1 (75 mg/kg bw), DOSE-2 (300 mg/kg bw), DOSE-3 (1200 mg/kg bw) and control group gavaged with carrier. The tested sample was given for 7 weeks orally. The result of blood biochemical parameters were not different significantly compared to control (p&gt; 0.05), as well as the results of hematology analysis. However, the NEUT level of female of DOSIS-2 showed lower and significantly different compared to control (p &lt;0.05). Histopathological evaluation of liver, kidney, heart, small intestine, and stomach organs illustrated that no lesions found in animals especially in DOSE-1 compared to control significantly (p&gt;0,05). Furthermore, this dose did not influence feed intake and body weight of animals in each sex. From this study, it could be concluded that the combination administrated at the dose of 75 mg/kg bw for 7 consecutive weeks did not affect blood biochemistry and hematology and also organ histopathology of kidney, liver, heart, small intestine, and stomach
