Abstract

Benthic animals are often used as biological indicators of water quality because benthos have relatively fixed habitats, with such characteristics, changes in water quality and the substrate where they live greatly affect their composition. Benthic density is also strongly influenced by its tolerance and sensitivity to environmental changes. The purpose of this research is to determine the type of macrozoobenthos in the Lalolara River, Kambu District, Kendari City. This type of research is descriptive research with observational sampling techniques. The observation technique used is to go directly to the deep field observation and sampling of the flow of the Lalolara River. The river is about 20 m wide meter is divided into 20 observation points. Sampling was carried out on each line transect where each transect consisted of 4 plots measuring 30 x 30 cm. The results showed that there were six types of benthos found in the river Lalolara namely: Tarebia granifer, Pleurocera acuta, Medulia carinata, Planobula armigera, Viviparus interitextus, Parapholyx effusa. Based on the results of the study, it appears that the species Tarebia granifer dominates both forms of the substrate. Also from the observations, the comparison between substrates shows that the sandy substrate has a large number of individuals with a higher diversity than the silty substrate Keywords: Diversity, Bentos

Abstract

Education is an effort to change behavior which includes three aspects, namely, cognitive aspects, psychomotor aspects and affective aspects. The assessment instrument used can be an assessment rubric containing performance achievement categories.  In simple terms, a rubric is defined as an assessment reference that shows a number of criteria for displaying the process or results of students' work. The use of rubrics in assessment will provide a real picture of student abilities. This research is a qualitative descriptive type of research which aims to determine teachers' difficulties in preparing assessment rubrics. This research was carried out at SMP Negeri 3 Kolaka using the interview method with biology teachers at the school. Research results show that teachers do not experience difficulty in preparing assessment rubrics. Assessment rubrics really help teachers find out student learning outcomes. Keywords: Teacher Difficulty, Rubric, Biology Learning

Abstract

Soursop leaf extract (Annona muricata L.) contains a many potential active compounds, one of which is antifungal. Bolu Paranggi is a traditional cake from Mandar (West Sulawesi), made from wheat flour and brown sugar so it is at risk of being damaged and overgrown with fungus. This study aimed to extract soursop leaves using double RO (Reverse Osmosis) water solvent with variations in extraction time and the ratio of soursop leaf mass and water volume, identify groups of secondary metabolites compounds from soursop leaf water extract, isolate and identify fungi in Paranggi Bolu cake, and perform antifungal activity test of soursop leaf extract against fungi isolated from Paranggi Bolu cake. Extraction of soursop leaves using double RO water as a solvent with maceration for 24 hours and heating for 15 minutes with a variation of the ratio of soursop leaf mass and water volume of 1:1; 1:1.5; 1:2; 1:2.5; and 1:3. The analysis of the secondary metabolite compound was analyzed using the phytochemical test method and antifungal activity using the agar diffusion method on PDA (Potato Dextrose Agar) media and then measuring the inhibition zone using 6 mm diameter paper discs. The results showed that extraction with the heating method for 15 minutes produced more extract than the 24-hour maceration method at room temperature (RT), where the highest amount of extract was obtained from the ratio of soursop leaf mass and water volume of 1:3. The results of the phytochemical analysis of soursop leaf water extract, both heating and maceration methods, contained flavonoids, alkaloids, terpenoids, steroids and saponins, and antifungal activity tests against Aspergillus isolated from Bolu Paranggi showed weak antifungal activity at extract concentrations of 5,000 ppm - 50,000 ppm. with an inhibition zone diameter of 2 mm. Keywords: soursop leaf extract, antifungal, Bolu Paranggi cake
