Abstract

Scientific literacy skills are very important skills to be mastered in learning activities in the 21st century. The objective of this study is to analyse the profile of scientific literacy skills of biology students of the class of 2017 at State University of Malang. This study is quantitative descriptive research. The respondents of the research were biology students in Endocrinology class,.The data were collected by conducting tests in the form of multiple-choice questions which were developed based on Test of Scientific Literacy Skills (TOSL) indicators that have been validated by material experts. The results showed that the literacy level of 25 7th biology students is still in the category of far below on five indicators with detail of the average scores, namely: identifying valid arguments with a mean value of 32; evaluating the use and misuse of information with a mean value of 16; justify inferences, predictions, and conclusions based on quantitative data with a mean value of 16; solving problems using quantitative skills including probability and statistics with a mean value of 44; understanding and interpreting basic statistics with a mean value of 24. In the other four indicators, the 25 biology students had a good level of scientific literacy, namely on indicators of understanding the design elements of research and how it affects scientific findings or conclusions with a mean value of 76; creating a graphical representation of the data with a mean value of 72; reading and interpreting graphical representations of data with a mean value of 80; and evaluating the validity of the source with a mean value of 80..

Abstract

Diabetes mellitus (DM) is a metabolic disorder characterized by chronic hyperglycemia. The prevalence of DM has been reported to increase from year to year. T2DM is characterized by insulin resistance, Leptin have an effect on insulin secretion, glucose and insulin will decrease due to leptin secretion. However, low levels of leptin that exceed the normal limit will interfere with insulin work so that it triggers diabetes caused by insulin resistance. Black soybean tempeh and purple sweet potato have therapeutic potential for people with T2DM. Both contain high antioxidants This study aims to determine the effect of the combination of black soybean tempeh extract and purple sweet potato on leptin hormone levels in DMT2 rat model. The experimental animals in this study were male white rats of the wistar strain which were divided into 6 groups. Preparation of hyperglycemic rats by feeding high-fat diet for 30 days, 10% sucrose drink for 30 days and streptozotocin injection at a dose of 35 mg/kg BW in 0.1 citrate buffered saline pH 4.5. Treatment using extract and purple sweet potato for 30 days. Mice were dissected and blood serum was taken for analysis of leptin hormone levels. Based on the results of the research data, there was an effect of the combination of black soybean tempeh extract and purple sweet potato on the leptin hormone levels in DMT2 rat model.
