<![CDATA[Begonia multangula Blume. has acid sensation and it spread abundant on the western mountains of Java. While result of Periodontitis sufferer’s krevicular epitel investigation shows Porphyromonas gingivalis sticking portion are 5 – 20 times greater than another bacteria. Research about antibacterial activity of the stem and leaf extracts of B. multangula on P. gingivalis has been studied. This research using two methods of extraction i.e fresh extract and maseration with etanol and aquades as solvent. Volume extract tested are 10 µL and 20 µL with aquades and etanol 48% as negative control. This research using disk difution method with three replications. Incubation process during 40 hours in anaerob jar 37 ºC degree. The results showed that all of the extracts have bactericide activity toward P. gingivalis, while two negative controls has no show mentioned bactericide activity. The biggest bactericide activity owned by etanol extract of B. multangula’s stem, while the smallest bactericide activity owned by aquades extract of B. multangula’s leaf. Obstruction Power Index (Indeks Daya Hambat, IDH) of all extract inclined low.]]>

<![CDATA[Berbagai aspek pengobatan atau pelayanan kesehatan yang modern di Indonesia sudah sangat berkembang. Namun, mayoritas masyarakat Indonesia masih memanfaatkan pengobatan atau pelayanan kesehatan tradisional. Hal tersebut disebabkan karena Indonesia memiliki budaya pengobatan dengan memanfaatkan tanaman obat secara turun-temurun di setiap daerahnya. Salah satu daerah yang mayoritas masyarakatnya memanfaatkan tanaman obat ialah Kota/Kabupaten Sukabumi. Penelitian ini bertujuan untuk mengungkap peran generasi muda dalam penelitian yang memanfaatkan teknologi di masa pandemi serta mengetahui potensi dan manfaat tanaman yang sering digunakan sebagai obat oleh masyarakat Sukabumi. Penelitian ini dilakukan secara kolaboratif dengan melibatkan 47 orang mahasiswa Pendidikan Biologi Universitas Muhammadiyah Sukabumi sebagai reponden yang mewawancarai informan kunci dari setiap daerah atau domisili mahasiswa yakni di Daerah Sukabumi. Hasil dari wawancara yang terdiri dari nama daerah, pengobatan penyakit, cara meracik/menggunakan, ciri tumbuhan, dan foto tumbuhan dimasukan ke dalam Google Form sebagai instrument penelitian. Teknologi digital sangat menunjang dalam menghimpun data penelitian seperti halnya Google Form. Dari hasil data tersebut, ditemukan sebanyak 47 informan, 56 spesies tumbuhan dan 12 famili tumbuhan obat yang biasanya digunakan oleh masyarakat Kota/Kabupaten Sukabumi sebagai obat tradisional.]]>

<![CDATA[This study aims to find out how students' critical thinking skills after learning using Outdoor Learning method assisted by virtual media field trip on learning biology material of coral reef ecosystem. This type of research is quasi experimental research with 2 class research population taken from class X SMA. The sample of this research was chosen by using purposive sampling technique. The research design used in this research is Nonequivalent Control Group Design. The instrument used in this study is a matter of as many as 7 test questions that each have been declared valid and reliable. Based on the data requirement test, it is known that the research data is normally distributed and the two classes have the same variance (homogeneous). From the data analysis it is known that the mean posttest grade of the experimental class with the learning using the Virtual Field Trip media aid is 70.76 and the mean posttest of the control students with the learning not using the Virtual Field Trip media is 55.23. There is a significant difference to student learning outcomes, it is proved by Z-test obtained Zcount (2.13> 1.96) then this research rejects H0 and receives H1. Thus, it can be concluded that there is influence of learning outcomes on the ability of critical thinking of students who follow the learning method using Outdoor Learning media-assisted Virtual Field Trip on the material of coral reef ecosystem. Keywords: Critical Thinking, Test Problems, Virtual Field Trip.]]>

<![CDATA[Masalah dalam penelitian ini adalah siswa mengalami kesulitan dalam memahami konsep, terutama pada konsep pemanasan global karena merupakan salah satu materi yang sulit dan ada beberapa konsep yang dianggap abstrak oleh siswa, sehingga dapat menimbulkan persepsi yang berbeda oleh siswa serta dapat menimbulkan miskonsepsi. Penelitian ini bertujuan untuk mengidentifikasi miskonsepsi siswa menggunakan tes diagnostik (two-tier test) setelah pembelajaran model predict-observe-explain (POE), kemudian menganalisis penurunan miskonsepsi siswa. Penelitian ini dilaksanakan di SMPN 5 Kota Sukabumi. Penelitian ini merupakan penelitian deskriptif dengan desain penelitian one-group-pretest-posttest Design. Sampel yang digunakan diambil dari populasi dengan teknik purposive sampling, yaitu kelas VII A dengan jumlah sampel sebanyak 41 orang. Teknik pengumpulan data dilakukan dengan tes diagnostik (two-tier test) yaitu soal pilihan ganda dengan dua tahap pemilihan jawaban, dan lembar observasi. Instrumen soal terdiri dari 10 soal masing-masing dengan 3 pilihan jawaban dan 4 pilihan alasan. Hasil penelitian menunjukkan bahwa terdapat miskonsepsi pada saat pretest. Penurunan miskonsepsi siswa setelah pembelajaran model POE adalah rata-rata 66% dan tiap konsep adalah 64,98%. Hasil penelitian dapat disimpulkan bahwa pada pembelajaran POE ini dapat dijadikan atlternatif pembelajaran untuk mengurangi miskonsepsi dapat dilihat dari nilai siswa antara sebelum pembelajaran (pretest) dan setelah pembelajaran posttestyangmenunjukkan penurunan miskonsepsi.Kata Kunci: Tes Diagnostik (Two-Tier Test), ModelPredict-Observe-Explain(POE), Miskonsepsi, Pemanasan Global]]>

<![CDATA[Binuangeun Beach, Lebak Regency, Banten Province, is one of the south coasts of Java which is still natural and virgin. This condition holds biological potential, one of which is macroalgae. Coastal community interactions with the potential of algae is part of everyday life. This article aims to reveal the potential of macroalgae found on the coast based on the knowledge of the people. Efforts to collect information/ emic from the community are carried out by collecting specimens using the Quadrant Transect method for sampling macroalgae species, then Plant Interviews are carried out to record community emics about the use of macroalgae found in the field. The Plant Interview was conducted in a structured manner. Interviews were conducted with two key informants from the local community. From the observations obtained 11 species. Among the beneficial species, it is noted that some of the species used are Ulva lactuca which can be used as food/ lalab; Turbinaria ornata is used as a trading / traded commodity, Sargassum sp as a trading/ traded commodity, foodstuff, and medicine; Halimeda tuna is used as paint and chalk and Enteromorpha compress is consumed. From these data it can be concluded that Binuangen Beach Banten has the potential to be developed into a source of additional nutrition, commercial and medicinal properties.]]>

<![CDATA[The purpose of this study was to determine the effect of contextual learning models based on hands-on activities on students' psychomotor abilities. This type of research is a quasi-experimental using pretest posttest control group design. The results showed the psychomotor ability of students in the experimental class averaged 79.63 which was categorized as "good" while the control class obtained an average of 68.93 which was also categorized as "good". Hypothesis testing using t test shows the results of tcount = 4.73 while the t table = 2.002 so that H0 is rejected and Ha is accepted. This means that there is a significant difference between learning using hands-on contextual learning models compared to contextual learning models based on conventional practicum student psychomotor abilities. The results of the correlation coefficient test, the experimental class got the value of rxy = 0.9965 and the contribution was 99.30% while the control class was rxy = 0.987 and the contribution was 97.42% with the value of r (0.05) (30) = 0.361. Thus rcount> rtable which means that there is a very strong relationship between psychomotor abilities and cognitive knowledge on water pollution material based on the interpretation coefficient interpretation table in the two classes.]]>
