Abstract

This study aimsto determine the degree of similarity of plankton in the waters of the mangrove ecosystem Gampong Pulo Sarok District of Singkil, Aceh Singkil. This research was conducted in January 2016. The method used is purposive sampling with mementukan 3 stations by mangrove species at each location. Sampling plankton based at a different time in the morning, afternoon and evening using plankton planktonet No. 25. Data were analyzed by using the similarity index formula to get the value of similarity at each station. In supporting parameters measured were temperature, salinity, brightness, depth, pH, and DO. The results showed that the plankton found in every station in the waters of the mangrove ecosystem Gampong Pulo Sarok District of Singkil, Aceh Singkil as many as 36 species. Level Parallelism (IS) in pulo Sarok was ranged from 66.66% to 94,74%.In which is meant the degree of similarity of plankton in the high category. Penelitian ini bertujuan untuk mengetahui tingkat kesamaan plankton pada perairan ekosistem mangrove Gampong Pulo Sarok Kecamatan Singkil, Kabupaten Aceh Singkil.Penelitian ini dilakukan pada bulan Januari 2016.Metode yang digunakan adalah purposivesampling yaitu dengan mementukan 3 stasiun berdasarkan jenis mangrove pada tiap lokasi.

Abstract

An experimental study on the implementation of guided inquiry learning method to improve students’ understanding and science processing skills in the concept of characteristics of organism has been conducted at MTsN Rukoh Banda Aceh in class VII. The aims of this study were (1) to determine the understanding of the concept of characteristics of living things through the application of guided inquiry learning, (2) to find out the improvement of students’ science processing skills in the concept of characteristics of living things by using guided inquiry learning, and (3) to determine the difference of understanding enhancement of the concept among the students who get guided inquiry learning. The data were analyzed by using SPSS 16.0 for Windows. The results showed that (1) there was an improvement of understanding of the concept in the experimental class with an average value was 61.95, while the control class was 35.70 with the difference was 26.25 and (2) the observation of teachers' activities showed that the interactions of teachers and students developed better compared to conventional learning. It can be concluded that (1) there was a significant difference between the application of guided inquiry method and conventional methods to increase students 'understanding of concepts (2) there was an increasing of students’ understanding of the concept and science processing skills through the implementation of guided inquiry learning.

This study aims to determine differences in the students' critical thinking skills through the application of cooperative learning jigsaw with conventional learning the concepts of environmental pollution in SMA 12 Banda Aceh. Data were collected in April 2016. The method used in this study was an experimental method with pretest posttest control design. The research was conducted in two classes, namely X-IPA 1 as the experimental class and X-IPA 2 as the control class. The instrument used in this study using multiple choice questions to assess students' critical thinking. Data analysis used independent sample t-test with SPSS 16.0 for Windows at significant level of 0.05. T test results showed tvalue>t table was to think critically 6.633> 2.68. The conclusions show that there are differences in critical thinking ability of students to use the application model of cooperative learning jigsaw with the conventional concept of environmental pollution in SMA 12 Banda Aceh.
