Abstract

The research on effect of traditional drying process againt proximate composition of the payangkah fish nike has been done. A number of payangkah fish nike samples has been taken from the Tondano lake, divided into two parts, i,e, fresh samples and other parts were traditionally dried at temperature range of 37°C for 24 hours. The proximate composition of wet and dried samples respectively specified was water content of 83.157%, protein 13.128%, lipid 1.48%, ash 2.033%, crude fiber 0.65% and carbohydrate 0.2%. While for dry samples the water content of 9.59%, protein 67.434%, ash 5.065% and crude fiber 0.64%. The results shows that traditional drying process has positive influence against some parameters on proximate composition of the payangkah fish nike.

Abstract

Of research on application of Case Based Learning Model on Material of Buffer Solution to Student Result of Class XI IPA of SMA Negeri 1 Kawangkoan. The purpose of this research is to know the difference of student learning resultusing conventional case-based learning model on buffer material. The research method used is experimental research method with the research design used is Posttest Only Control Group Design. Data collection technique is posttest. The research population is all students of SMA Negeri 1 Kawangkoan, while the samples taken are two randomly selected classes, that is class XI IPA 4 as experiment class with 25 students and class XI IPA 5 as control class with 25 students. Based on the results of research analyzed by t-test at the real level (α) = 0.05 obtained data that tcount = 2.494 and ttable = 1.677 according to the study criteria, if tcount> ttable then reject H0, so it can be concluded that there are differences in results student learning is taught by case-based learning model with student learning outcomes using conventionallearning method.

Abstract

The purpose of this study was to determine the percentage of students' critical thinking skills in the chemical reaction in solution topic by using the STEM approach. This research was conducted in the department of chemistry, FMIPA UNIMA in the 2019/2020 academic year. The descriptive qualitative was using for this research with 29 students from first semester of chemical education department as research samples. Data Collection was carried out by 10 posttest essay that include student critical thinking ability. The result of the test show the ability to answer the critical thinking skills are 17,2% for very critical thinking, 44,83% for critical enough ; and 37% for less critical.
