Abstract

The world of education plays a significant role in the development of students. So, to facilitate the learning process for students is the main task of a teacher. For this reason, teachers are not only required to make the learning atmosphere comfortable and exciting. However, the teacher must also be able to improve maximum learning outcomes for students. This study aims to determine whether the application of interactive PowerPoint learning media in the classroom can help improve student's learning outcomes in class VIII on the material of the human movement system as well as research. In contrast, the object used in this research is the application of learning media using interactive PowerPoint media at Arrival Junior High School Kaima. The type of research used is classroom action research by applying two cycles of data collection obtained from observations of teacher activities and observations of student activities as well as tests before and after the action and documentation. The data analysis technique used in this study is a qualitative descriptive technique. Based on the study results, the class action that the researchers had carried out found that before the action was taken, the student's learning outcomes were 0%, or the number of students who had completed was absent. At the same time, there was an increase of 83.33% in the first cycle, and in the second cycle, again experienced an increase of 100%. This means that learning using interactive PowerPoint media is proven to help teachers improve learning outcomes in Kaima Adventist Junior High School class VIII students.

Abstract

Butini fish is a resource wealth of fauna found only in the East Complex Malili Luwu, South Sulawesi. The necessary information about the morphological characters (morphometric and meristic) to determine the management of fish resources. The purpose is to assess the diversity of populations based on morphometric meristik. Sampling is based on descriptive methods and fish samples taken to determine the diversity of phenotypes based on the depth of each morphometric character. Calculating morphometric characters using the main component analysis to obtain the correlation between the character and the grouping of individuals based on morphometric characters. Calculation meristik characters include the number of fingers, the number of fins and scales, namely the number of fingers of the dorsal fin, anal fin radius, the radius of the ventral fin, pectoral fin radius, the radius of the caudal fin, scales on the rib line, scales above the rib line, scales below the ribs, scales in front of the dorsal fins, scales on the cheeks, around the body scales, scales around the tail shaft. The analysis showed that the first two principal components contained the greatest information, with a cumulative range of 80%. All the characters' morphometric first role is a major component. The character who plays the main component of the length of the head in front of the eyes, long upper jaw, lower jaw length, high cheeks, and the length of the radius of a weak base ventral fins showed great correlation to the diversity of forms. Main components analysis also showed that butini fish, at any depth, showed no grouping. This suggests that the fish species observed was one (one unit of population). In calculating the value of phenotypic diversity of each character, butini generally fish in the lake Towuti show morphometric characters with the highest diversity value and the lowest given by the total length and high under the eyes. In the calculation of the formula derived characters meristik flipper fingers that D1, V-VI. D2. I, 8-11; dan D1, V-VI, D2. I, 8-10.
