Pengaruh Degradasi Enzim Proteolitik Terhadap Aktivitas Angiotensin Converting Enzyme Inhibitor Bekasam Dengan Lactobacillus Plantarum B1765

This research studied the effect of digestive enzyme degradation on the Angiotensin Converting Enzyme Inhibitor (ACEI) activity and the stability of bekasam peptide and ACEI activity. Water extract of bekasam was subjected to pepsin and trypsin. The stability of peptide was measured from the changes of peptide concentration before and after treatment by those enzymes. The stability of ACEI activity was measured by hypuric acid liberated from Hip-His-Leu as ACE substrate and determined by spectrophotometer. The results showed that proteolytic enzyme degradation did not affect the concentration of peptide (p>0,05) and the mean concentration 36.72. It was closely related with the ACEI activity that did not change significantly before and after digestion by pepsin and trypsin (p>0,05) and the mean ACEI activity was 70.73. It showed that ACEI activity of bekasam did not change by the degradation of digestive enzyme

THE EFFECTIVENESS OF QUESTION ANSWER RELATIONSHIP (QAR) STRATEGY IN TEACHING READING COMPREHENSION

As a language skill, reading plays an important role because reading has become part of our daily lives. Reading is also an important way to improve pupils apos; common language skills in English. However, reading is not easy because when students read, they also need to understand what is being read. One way to help students understand what they read is to use a question-and-answer strategy (QAR). The aim of the study was to obtain empirical evidence of the effectiveness of the QAR strategy in teaching an 11th grade student SMAN 1 Bangsal in the 2016-2017 academic year. The design of the study was quasi-experimental, using design only for two groups after testing, which passed through two classes: the pilot group and the control group. After the tests were performed, the post-test showed that the average score obtained by the experimental class was 81.12 and the control class was 72.75, while both classes were equal. It was proven by the result of homogeneity test, that Fh was lowest than Ftable (1.32 1.89). From the result of t-test, it was obtained the tvalue was 9.05 higher than ttable (9.05 1.89). It means that H2 is accepted and the Ho is rejected. So, there is a significant effect of using QAR strategy on students reading comprehension ability.
