Abstract

A The research aims to determine the effectiveness of discovery learning models assisted by puzzle mind maps on the activities and learning outcomes of the Structure and Function of Animal Tissue Materials. This research was conducted at SMAN 13 Semarang in the Odd Semester Academic Year 2018/2019. This research is a Quasi Experiment study with Nonequivalent Control Group Design. The population in this research were all students of Class XI MIPA of SMAN 13 Semarang. The sample used was Class XI MIPA 1 and XI MIPA 2 which was taken by purposive sampling technique. The results showed that the learning outcomes showed that there were no significant differences between the learning outcomes of the control class and the experimental class (sig. ˃ 0.05). Data on student activity obtained by observation and filling in questionnaire sheets showed that 100% of the experimental class students entered very active and active category, while in the control class showed that 89.3% of students entered were very active and active category. This shows that the experimental class is able to surpass the indicator ≥ 90% in the student activity. The conclusion is the application of discovery learning models assisted by puzzle mind map of the Structure and Function of Animal Tissue Materials effectively applied to increase student activity but not to improve learning outcomes.

Abstract

The aim of this study was to examine the activity of various doses of E. grandiflorus leaf extract on the number of leukocytes, neutrophils, lymphocytes and histological features of the spleen in male rats induced by sheep red blood cells (SRBC). 25 rats were divided into 5 groups. The negative control was given 1% Na.CMC, the positive control was given an immunostimulant drug, and the three treatment groups received doses of 100mg/kg, 200mg/kg, and 400mg/kg. Oral treatment for 7 days. SRBC was injection on the 8th day. On the 13th day termination was carried out. The average leukocyte results were 6.54x103 cells/μL (K−), 6.22x103 cells/μL (K+), 10.8x103 cells/μL (P1), 10.98x103 cells/μL (P2), and 11.2x103 cells/μL (P3). The results of the number of lymphocytes have a percentage of 44% (KN), 50% (KP), 45% (P1), 52% (P2), and 50% (P3). The neutrophil count results were 44.3% (K−), 35% (K+), 37.4% (P1), 30.4% (P2), and 31.9% (P3). The results of the white pulp diameter measurements had an average of 418.0 µm (K-), 440.8 µm (K+), 471.2 µm (P1), 489.8 µm (P2), and 422.0 µm (P3). The averages obtained from germinal center measurements were as follows 252.1 (K-), 225.8 (K+), 212.8 (P1), 216.3 (P2), and 198.4 (P3). ANOVA showed no significant white pulp diameter difference (p > 0.05). In conclusion, the immunostimulatory activity test on rejasa extract on the parameters of leukocytes, neutrophils and lymphocytes had a normal average number. Meanwhile, administration of rejasa extract to the spleen histology have no significant immunostimulating activity.
