The average students' chemical learning outcomes are still low, the low learning outcome is influenced by several factors, including students still consider that chemistry as one of the scary, difficult to understand and less interesting lessons. Therefore, the research wants to vary the learning process in the classroom by applying the learning model of Discovery Learning with Group Investigation model. This research was aimed to find out the students’ achievement differences of chemical subject by using Discovery learning and  Group Investigation model. The research is quasi experimental research. The population of this research were class X MIPA in SMAN 9 Bengkulu City, and the sample were X MIPA 2 and MIPA 3. This research using two experimental classes, that is class X MIPA 2 applying Group Investigation model and X MIPA 3 applying Discovery Learning model. Analysis of the data used is mean values, normality test, homogeneity test, and t-test. Post-test mean values for first experiment class is 78,12, but for second experiment class is 81,3. To determine whether the differences of student’s learning outcomes between both of experiment classes or not, we use t-test by using the differences between student’s pretest and posttest values, tcount > ttable (2,17 > 1,67). The result of this research showed that Ha accepted, in other words is a significant differences in learning outcomes of student’s applying Discovery Learning and Group Investigation model.

This study aims to determine the differences in student chemistry learning outcomes between classes that apply the Student Teams Achievement Division (STAD) learning model with a class that applies the Team Games Tournament (TGT) learning model to chemical compounds. This type of research is quasi-experimental with a population of class X IPA Academic Year 2018/2019 which amounts to 204 students. Samples were obtained from the results of the normality test and homogeneity test, namely class X IPA 4 which applied the STAD learning model with cation anion media and class X IPA 6 which applied the TGT learning model with anion cation card media. This study was conducted in January-March 2019. Analysis of the data used is the average (mean), normality test, homogeneity test, and hypothesis testing (u test). In general, the two models were able to improve learning outcomes, where the STAD learning model obtained higher results, namely 79.723. Data on students' chemistry learning outcomes were obtained from the pretest and posttest values where the average value of the increase in cognitive learning outcomes for the STAD class and the TGT class was 57,222 and 46,944. Through a series of statistical tests hypotheses were tested using the u test with a significant level (? <0.05) indicating the value (Sig. 2-tailed) of 0,000. This shows that there are significant differences in learning outcomes between classes applying the STAD learning model assisted by anion cation cards with classes that apply the TGT learning model assisted by anion cation cards.

Introduction: Cigarette smoking is a prime risk factor for cardiovascular morbidity and mortality. Chronic smoking results in autonomic dysfunction leading to increased cardiovascular risk in smokers. The present study was planned to study the effect of smoking on the Cardiovascular Autonomic Functions among smokers. Materials and Methods: Fifty male subjects who were in the age group of 25 to 45 years. They were grouped into 25 smokers and 25 non-smokers. The participant subjects were selected among the staff members, residents and the patients from the routine OPD in SVIMS. Prior to study, they were informed about the procedure and the purpose of the study tests and written consents were obtained from them. The Cardiovascular Autonomic Function Tests were assessed by using a POLYGRAPH which was available in the department. Results and Conclusion: After applying the ‘t’-test for the difference between the two sample means, it was observed that there was a highly significant difference between the mean values of the BMI(i.e.p<0.01) and the para-sympathetic function tests among the smokers and the non – smokers(i.e.p<0.00). The Resting Heart Rate had significantly increased and the Deep breathing difference, the postural tachycardial index (Response to standing) and the Valsalva Ratio had significantly decreased in the smokers as compared to those in the non – smokers. After applying the ‘t’-test for the difference between the two sample means, it was observed that there was no significant difference between the mean values of the Postural hypotension test (i.e. p>0.05) and that there was a highly significant difference between the mean values of the Sustained handgrip test in the smokers and the non – smokers (i.e. p<0.00). KEY WORDS: Cardiovascular autonomic function tests, Smoking, Resting heart rate.

      This study aims to determine the effect of the Type STAD Cooperative Learning model on mathematical problem solving abilities. The data collection technique was obtained by means of a test in the form of description questions and documentation in the form of a list of student names. The research instrument used was 3 pre-test and post-test questions. The data analysis technique used is the normality test, homogeneity, t test with the technique of paired samples t-test and independent t-test.      The results showed that, the paired sample t-test on the problem solving ability before and after treatment with STAD obtained an average value of 50.29 to 83.71 with a significance of 0.000 <0.05. This means that the students' scores before and after STAD learning have differences in the average mathematical problem solving abilities. Based on the results of the paired sample t-test on the ability to solve mathematical problems before and after treatment using conventional learning models, the average value was 44.57 to 75.79 with a significance of 0.000 <0.05. This means that there is a significant increase before and after conventional learning. Based on the results of the independent samples t-test, the mean values were 83.71 and 75.79 with a significance value of 0.009 <0.05. This means that there is a difference in the average problem-solving ability of students in STAD learning with students in conventional learning. It can be concluded that the STAD type of cooperative learning model has an effect on students' problem solving abilities in mathematics.
