Abstract

Abstrak: Mulut memiliki mikrofloranormal bakteri sebagai pertahanan tubuh. Bakteri Streptococcus mutans merupakan bakteri yang berkelompok pada permukaan gigi yang memiliki peranan dalam pembentukan karies gigi. Daun dan batang Ciplukan (Physalis angulata L.) mengandung polifenol, flavonoid, dan etanol serta antioksidan yang kuat yang diduga memiliki aktivitas antimikroba yang sangat baik. Tujuan penelitian ini yatu untuk mengetahui daya antibakteri obat kumur ekstraksisi etanol campuran daun dan batang ciplukan (P. angulata L.) terhadap bakteri Streptococcus mutans. Metode penelitian bersifat eksperimental murni laboratorium yang menggunakan kulturisasi bakteri S. mutans. Uji daya antibakteri menggunakan cara dengan dilusi cair dan dilanjutkan dengan dilusi padat. Uji analisis statistik menggunakan uji deskriptif. Dari hasil penelitian menunjukkan bahwa pada konsentrasi 15% obat kumur ekstraksi etanol campuran daun dan batang ciplukan mempunyai kadar hambat minimal (KHM) dan kadar bunuh minimal (KBM).   Formulasi ini bisa direkomendasikan untuk dilakukan penelitian lebih lanjut agar bisa digunakan oleh masyarakat yang tinggal dikawasan suhu dingin.Kata Kunci: Ciplukan, obat kumur, Streptoccus mutans. Abstrak: The mouth has microfloranormal bacteria as a defense of the body. Mutant Streptococcus bacteria are bacteria that cluster on the surface of the teeth that have a role in the formation of dental caries. Ciplukan leaves and stems (Physalis angulata L.) contain polyphenols, flavonoids, and ethanol as well as powerful antioxidants that are thought to have excellent antimicrobial activity. The purpose of this study was to find out the antibacterial power of ethanol extraction drugs mixed with leaves and stems ciplukan (P. angulata L.) against bacteria Streptococcus mutants. The research method is purely experimental laboratory that uses the culture of bacteria S. mutants. Antibacterial power test using a means with liquid dilution and continued with solid dilution. Test statistical analysis using descriptive tests. From the results of the study showed that at a concentration of 15% mouthwash ethanol extraction mixed leaves and stems ciplukan have minimal levels of bland (KHM) and minimal kill rate (KBM).   This formulation can be recommended for further research so that it can be used by people living in cold temperatures.Keywords:  Ciplukan, mouthwash, Streptoccus mutants

Abstract

This study aims to development of media mobile learning based on android for learning the biology of nervous system material and to determine the effectiveness of media mobile learning based on android in improving students' conceptual understanding. The type of research used was development (R&D), population, and sample, namely class XI IPA 2 as many as 30 students at one of the public high schools in Bogor Regency which was carried out from January to May 2020. This development research procedure used a model (4D) consisting of 4 stages, namely Define, Design, Develop, and Disseminate. The instruments   used   were   tests (pre- test and post-test), response questionnaire sheets, and documentation. The implementation of deployment trials was carried out using a one group pre-test and post-test research design. The results showed that the media mobile learning got a very feasible category. This is based on the average percentage of the assessment from the expert validation team, namely 82.75%. Media mobile learning Android-based on learning the biology of the nervous system material can improve students' understanding of concepts and almost all students respond positively.

Abstract

Biodiversity was the important topic for biology learning to support environmental sustainability, especially in Echinoderms biodiversity. The purpose of this study was to identify Echinoderm species found on Pangumbahan Beach, Ujung Genteng, Sukabumi and develop e-booklet teaching materials for students. The research procedure is field observation with the exploration of transect methods at 3 stations representing 3 ecosystems, namely rocky sand ecosystems, coral ecosystems, and seagrass meadow ecosystems. Sampling was carried out by transecting a combination of plots with a plot size of 5 x 25 meters at three different stations and the develop the learning media with research and development method. The results of the study found 3 classes, 4 orders, 4 families, and 4 genera of Echinodermata consisting of 7 species, namely Ophiocoma scolopendrina, Ophiocoma erinaceus, Ophiomastix annulosus, Diadema setosum, Tripneustes gratilla, Synapta maculata, Euapta gedeffroyi, and Holothuria atra. The validation results of the booklet receive an average score of 88%, placing it in the category of very feasible for use in school learning activities.  This media can empower students’ knowledge about biology topic, expecially in Echinoderm to support environmental sustainability.
