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.</em></p> Nurcholifatun Nurcholifatun Copyright (c) 2024 Nurcholifatun https://creativecommons.org/licenses/by-sa/4.0/ 2024-04-30 2024-04-30 4 2 52 62 10.36312/biocaster.v4i2.253 Identifikasi Jenis Zooplankton di Sepanjang Perairan Sungai Jangkok Kota Mataram https://e-journal.lp3kamandanu.com/index.php/biocaster/article/view/255 <p><em>Zooplankton is animal plankton, which plays a role as primary consumers in aquatic ecosystems and as a link in the aquatic food chain.

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.</em></p> Safnowandi Safnowandi Copyright (c) 2024 Safnowandi https://creativecommons.org/licenses/by-sa/4.0/ 2024-04-30 2024-04-30 4 2 63 71 10.36312/biocaster.v4i2.255 Penerapan Model Pembelajaran Active Learning dalam Meningkatkan Aktivitas dan Hasil Belajar Biologi Siswa Kelas VIII https://e-journal.lp3kamandanu.com/index.php/biocaster/article/view/256 <p><em>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.</em></p> Zulhia Ariati Norma Hirliana Copyright (c) 2024 Zulhia Ariati & Norma Hirliana https://creativecommons.org/licenses/by-sa/4.0/ 2024-04-30 2024-04-30 4 2 72 80 10.36312/biocaster.v4i2.256 Efektivitas Ekstrak Daun Kemangi (Ocimum basilicum L.) terhadap Jumlah Hama Serangga yang Menyerang Tanaman Kacang Hijau (Phaseolus radiatus L.) https://e-journal.lp3kamandanu.com/index.php/biocaster/article/view/257 <p><em>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.).
