Abstract

Outdoor learning is a method in learning and teaching.  With outdoor learning, students can get to know the environment and  biological concepts. The purpose of this study was to determine the increase in students' understanding of the concept of the interaction between living things and the environment in the outdoor learning method. This type of research is a classroom action research (CAR) with two learning cycles.  The subjects of this study were students of class X SMPN 15 Kabaena Utara with 20 students. The data obtained were analyzed using descriptive analysis. The results showed that the students' understanding of the concept of  cycle 1 was 40.95 and cycle 2 was 70.5.  Based on the results of the study, it can be concluded that the outdoor learning method can improve the understanding of biological concepts in class X SMPN 15 Kabaena Utara.Keywords: Outdoor Learning Method, Biological Concept Students

Abstract

Students' critical thinking is needed, because during the learning process students develop ideas about the problems contained in learning. The aim of this research was to improve students' biology critical thinking skills. This research was conducted in the even semester of the 2013/2014 academic year. This type of research was classroom action research (CAR) with three learning cycles. The data sources of this research were an assessment using learning activity of observation sheets and student learning outcomes tests. The data obtained were analyzed using qualitative and quantitative data analysis. The success of the students’ activity action in cycle I with a mean score was 3.25 with percentage was 81.54%; Cycle II amounted to 3.2 with percentage of 80,05% and in cycle III amounted to 3.61 with percentage of 92%. Students' critical thinking skills in cycle I were 62.18 with percentage was 25.64%. The average achievement of students’ critical thinking skills test in cycle II was 83.08 with percentage was 94.87%. The average achievement of students' critical thinking skills test in Cycle III reached 85.38 with percentage 97.43%.  Based on the results of the research conducted, it was concluded that the application of the GI type of cooperative learning model could improve  the student’s activity and students' critical thinking skills in the material of the immune system at class XI IPA3 of Senior High School 2 Kendari.Keywords: Group Investigation, Student Activities, Critical Thinking.

Abstract

Baluran National Park is a Natural Resources Conservation area. Avifauna is a perfect indicator to determine environmental health and the value of biodiversity as a whole. This study aimed to assess the diversity of avifauna species and their abundance in Baluran National Park. This research using a combination line transect and point count method. The results showed that Baluran National Park has high species diversity. Species found during the study were 36 of 24 families. As many as 11% (4 species) of birds are in a large category, 39% (14 species) in a general category, 19% (7 species) in a frequent category, 6% (2 species) in an uncommon category and 25% (9 species) in a rare category. Based on the research results, it can be concluded that there are various kinds of avifauna in Baluran National Park.Keywords:  Avifauna,  Baluran National Park, Diversity, Line Transect, Point Count.

Abstract

Changes on the mangrove ecosystem, directly and indirectly, affect the living organisms associated with it, including Molluscs. This study aimed to investigating Molluscs species in mangrove ecosystem of Kendari Bay. It is descriptive research containing facts and natures of mangrove Mollusc species. This study conducted from September to November 2020. Observing and collecting the Mollusc organisms were carried out in four mangrove ecosystems like Bruguiera, Bruguiera/Rhizophora, Rhizophora, and Avicenia.  The method used in this research was an exploring technique by collecting and counting the found Mollusks. Indicators of observing the Mollusks included morphological characteristics and environmental parameters. Three important environmental parameters, like salinity, acidity (pH), and temperature, were measured during field works using hand refractometer, pH tester, and thermometer, respectively. This research indicates about 279 individuals of Mollusks found in all zones consisting of 17 species representing two classes, Gastropod (14 species) and Bivalves (3 species). During this research, the Gastropod Mollusks found Telescopium-telescopium, Terebralia palustris, T. sulcata, Cerithideopsilia cingulata, C. alata, Nerita squamulata, Cerithidea quadrata, C. obtusa, Latirus paetelianus, Cerithium kobelti, Chicoreus capucinus, Nassarius stolatus, N. niticusis, Siphonalia varicosus. For the three species of Bivalves are Polymesoda erosa, Anadora granosa, and  Sacostrea cucullata. The both species T. sulcata and S. cucullata positively dominated all total found Gastropods and Bivalves namely 21.86% and 3.943%, respectively. The three water quality parameters measured at research stations are still on tolerance limits for the collected molluscs. Keywords:   Molluscs, Mangrove Ecosystem, Kendari Bay

Abstract

Senggani is a plant from the Melastomataceae family and the genus Melastoma. This study aims to determine the effect and the best concentration of Senggani (Melastoma candidum D. Don) leaf and fruit extracts to suppress the growth of Escherichia coli and Staphylococcus aureus. The research design refers to the experimental research design. The independent variable (X) is Senggani leaf and fruit extract with a concentration of 1%, 5% and 10%, the total treatment in this study was 6 treatments so that the total treatment of the tested bacteria was 36 experimental units. The dependent variable (Y) is the inhibition of bacterial growth. The research method used a completely randomized design. The data analysis technique used was descriptive analysis and analysis of variance at the 95% confidence level and the LSD further test at the 95% confidence level. The results of the study concluded that (1) there was a significant effect on the concentration of Senggani (Melastoma candidum D. Don) leaf and fruit extract as a growth inhibitor for Escherichia coli and Staphylococcus aureus (2) Senggani (Melastoma candidum D. Don) leaf extract with a concentration of 10% was the best treatment to inhibit the growth of Escherichia coli and Staphylococcus aureus (3) The highest average diameter of the inhibition zone in E. coli given Senggani (Melastoma candidum D. Don) leaf extract with a concentration of 10% was 11.17 mm (4) The highest average diameter of the zone of inhibition in Staphylococcus aureus given Senggani (Melastoma candidum D. Don) leaf extract with a concentration of 10% was 10.16 mm.Keywords:  Senggani, Melastoma candidum D. Don, Antibacterial Activity
