Abstract

The lack of student participation in learning is caused by teachers not paying attention to students' psychological conditions, so that students experience difficulties in learning which has an impact on low motivation and student learning outcomes. The effectiveness of learning, learning motivation and learning outcomes need to be improved through a learning process using a cooperative model of The Learning Cell type, namely a concept that places more emphasis on raising questions which is the key to learning. The purpose of this research is to determine the increase in motivation and cognitive learning outcomes of students using the cooperative learning model type The Learning Cell. The type of research used is classroom action research which consists of two cycles, each cycle consisting of two meetings. This research measures the results of observations of the implementation of teacher and student activities, motivation and cognitive learning outcomes of students using observation sheets on the implementation of teacher and student activities, as well as questionnaires and evaluation tests. The results of the research show that the percentage of implementation of the results of observing teacher activities in cycle I was 82.57% which was included in the good category and cycle II increased with a percentage of 89.28% in the very good category, while the results of observing the implementation of student activities in cycle I was with a percentage of 60. % in the quite active category and increased in cycle II with a percentage of 85% in the very active category. Student motivation was obtained from the distribution of questionnaires in the first cycle which was in the good category at 80.60% and in the second cycle it increased to 82.56%, still in the good category. Student cognitive learning outcomes are obtained from evaluation tests that have been prepared and distributed to students at the end of each cycle, in cycle I it was 65%, so students were not yet said to be classically complete and continued in cycle II which experienced an increase of 87%, so student learning outcomes on the subject of interdependence in ecosystems, it is stated to be classically complete. Based on these results, it can be concluded that by implementing the cooperative learning model of The Learning Cell type, it can increase the motivation and cognitive learning outcomes of Biology students at SMP Negeri 2 Kayangan.

Abstract

Zooplankton is animal plankton, which plays a role as primary consumers in aquatic ecosystems and as a link in the aquatic food chain. The Jangkok River is one of the large rivers on Lombok Island. This river flows from the western slopes of Mount Rinjani through the Narmada area of ​​West Lombok Regency to downstream at Ampenan Beach. Many river flows provide functions and benefits for the continuity of life of the surrounding community. This research aims to identify zooplankton in the waters of the Jangkok River, Mataram City. This type of research is exploratory descriptive. Research procedures include taking zooplankton water samples horizontally and vertically. Data collection techniques use observation and documentation techniques. The data analysis technique uses the zooplankton abundance index. The research results show that there are 4 types of Zooplankton consisting of 4 species that have been discovered including Harpacticoid copepod, Parathemisto abyssorum, Cyclops bicuspidatus and Diaptomus sp.

Abstract

This research aims to determine the increase in student activity and learning outcomes through the application of the Active Learning learning model in biology lessons for class VIII students at SMP Negeri 12 Tasikmalaya. This type of research is Classroom Action Research (PTK). This research was conducted at SMP Negeri 12 Tasikmalaya. The population in this study were all class VIII students, while the sample used was 25 students. The instruments used in this research were observation sheets and test questions. Data collection techniques use observation and tests. The data analysis technique in this research is qualitative and quantitative data analysis. Qualitative data analysis is used to analyze data obtained from observations carried out in the first cycle and subsequent cycles, the data is collected and then concluded. Meanwhile, quantitative data analysis is used to process data in the form of numbers, both observation data and student learning outcomes (evaluation) data which are then processed into quantitative data in research. The results of this research show that, in cycle I, the student activity score was 2.5 in the quite active category and in cycle II it was 3.33 in the active category. For learning outcomes, the percentage of classical completeness in cycle I was 68% in the incomplete category and in cycle II it was 88% in the completed category. Thus it can be concluded that the application of the Active Learning learning model can improve the activities and learning outcomes of class VIII students at SMP Negeri 12 Tasikmalaya.

Abstract

Pests are a type of plant damage that can have fatal consequences for farmers, therefore pests need to be eradicated so that farmers' yields can increase, especially in green bean plants. Basil is one of the biodiversity that has the potential to be developed as a traditional medicine. This plant is a plant that has many benefits as medicine, vegetable pesticide, essential oil producer, vegetable and refreshing drink. This research aims to determine the effectiveness of basil leaf extract (Ocimu basilicum L.) on the number of insect pests that attack green bean plants (Phaseolus radiatus L.). The parameters observed were the number of insect pests before and after treatment. The object of this research was green bean plants, the number of treatments in this research was 4 treatments (0% basil leaf extract, 10% basil leaf extract, 20% basil leaf extract, and 30% basil leaf extract) and 6 replications. Research data is descriptive data. From the research data, it was found that there was a decrease in the number of insect pests before and after treatment in the K3 treatment, the number of insect pests before treatment was 12 and after treatment there were 11 insect pests. In treatment K1-K2 there was no decrease in the number of insect pests before or after treatment. In treatment K1, the number of insect pests before treatment was 9 and after treatment there were 14 insect pests. In the K2 treatment, the number of insect pests before treatment was 12 and after treatment there were 19 insect pests. The results of the study concluded that administering basil leaf extract (Ocimum basilicum L.) had no significant effect on the number of insect pests attacking green bean plants.

Abstract

Indonesia is known as a country that is abundant in various biological riches and their potential as medicines, so a review of natural antidiarrheal treatment methods using tamarind leaves was carried out. Diarrhea is a digestive disorder with a high prevalence rate, especially in developing countries. Diarrhea is a digestive system disorder characterized by stomach cramps, a liquid stool consistency, and an increase in the frequency of defecation more than 3 times in 24 hours. The research method used is to use literature review through online publications based on the Web, ResearchGate, Google Scholar and Scopus. The research sample used in this literature review was 22 articles. The research results show that the phytochemical content of tamarind consists of tannins, flavonoids, saponins, alkaloids, phenols and triterpenoids. The results of the analysis in the literature review show that tamarind leaves are an alternative natural treatment and are effective in inhibiting the growth of bacteria, for example the Escherichia coli bacteria that causes diarrhea.
