Exploration Of Rbc And Hgb In Mencit (Mus Musculus) Hyperololerinolemia

So far there is no clear information about RBC and HGB linkage with hypercholesterolemia, especially for arteriosclerosis and hypertension patient. In the future, this research is expected to add a repertoire of knowledge and people knew about hypercholesterolemia and the utilization of appropriate alternative medicine. A total of 20 mice (Mus musculus) age ± 2 months of hypercholesterolemia caused by cholesterol-rich diet (ad libitum). The data were analyzed by analysis of variance based on Randomized Block Design (RAK) 1% with 5 (five) groups and 4 replications (positive control, negative group, and the group of celery extract dose 0,5 ml with concentration 25%, 50%, 100%). It was concluded that HGB in line with RCB (either treated with celery extract or mice treated with hypercholesterolemia) and the provision of celery extract significantly did not affect RBC and HGB with total blood cholesterol level of mencit

Pengaruh Model Pembelajaran Langsung Berbasis Praktikum terhadap Keterampilan Proses Sains dan Kemampuan Berpikir Kritis Siswa

This study aims to determine the effect of practicum-based direct learning model on science process skills and students' critical thinking skills. This study is a quasi-experimental research with the Pretest-posttest Control Group Design. The sampling technique using Cluster Random Sampling. The sample in this study were students of class XI IPA 1 (18 students) as the experimental class and class XI IPA 2 (18 students) as the control class in AL-Hamzar High School Tembeng Putik. The research instruments used were learning implementation observation sheets, the science process skills observation sheets, and learning achievements tests. The data obtained were analyzed using the t test with the help of SPSS 16. The results of data analysis showed that the implementation of learning in the first meeting reached 81% and the second meeting 96% with a very good category. The students' science process skills in both classes show that students' science process skills varies. The students' critical thinking ability in the experimental class was higher than the control class. The results of pretest data analysis showed that students' critical thinking ability in the experimental class was 35.5 while the control class was 49.5. Students' critical thinking ability in post-test increased in the experimental class to 73.5 while the control class was 58.6. The results of the t-test show that tcount > ttable (3.45 > 2.04) so it can be concluded that the practicum-based direct learning model was affect toward students' science process skills and critical thinking ability

Pengaruh Model Pembelajaran Berbasis Masalah dengan Pendekatan Saintifik terhadap Keterampilan Berpikir Kritis Siswa

This study aims to determine the effect of the problem-based learning model (PBL) with a scientific approach to critical thinking skills of class X students of Al-Ma'arif Pandan Indah Islamic High School 2016/2017 academic year. The type of research used is quasi-experiment with Nonequivalent control group design. The population in this study were all students of class X Islamic High School Al-Ma'arif Pandan. The sample used consisted of two classes taken using nonprobability sampling techniques, namely class XA as the experimental class, and class XB as the control class. The technique of collecting data on the implementation of RPP using the observation sheet and critical thinking skills of students was measured using a test in the form of a description question that had been validated by 2 expert experts. Data analysis of critical thinking skills carried out by t-test found that t-count = 2.58> 2.042. Based on the results of the analysis it can be concluded that the problem-based learning model with a scientific approach significantly influences students' critical thinking skills

Profil Pemahaman Konsep Evolusi Mahasiswa Calon Guru Biologi FPMIPA IKIP Mataram

[Title: The Conceptual Profile of Prospective Biology Teacher FPMIPA IKIP Mataram]. The conceptual profile is a tool for analyzing the style or process of thinking, so the profile of understanding concepts is very important to study as a basis for designing and improving the quality of learning. This research is a descriptive study that aims to identify and explain the conceptual profile of prospective biology teacher FPMIPA IKIP Mataram. The subjects in this study included all biology students who regularly program evolutionary courses. The open-ended question is designed to collect conceptual profile data on the evolutionary biology students from FPMIPA IKIP Mataram. Identification or determination of conceptual profile is based on student responses or answers. Based on the results of the research and the limitations of the discussion, it is recommended that the development of textbooks that are free of misconception as a learning resource for valid biology prospective teacher, then lecturers as instructors, continue to study and teach about attitude, namely scientific attitudes, or thinking dispositions, and/or integrating attitudes in the lecture process. Besides that, in the lecture or learning process, the lecturer must facilitate or empower the style or process of thinking of students with various learning methods or strategies that emphasize thinking processes, including formal reasoning, and analogical teaching strategy
