Abstract

Salah satu pembelajaran yang menekankan penguasaan keterampilan berupa kemampuan memecahkan masalah adalah Ilmu Pengetahuan Alam (IPA). Kemampuan ini termasuk ke dalam aspek critical thinking. Karakteristik siswa SMP yang sudah mulai mampu berpikir kritis secara mandiri perlu dilakukan pengembangan kemampuan tersebut ke depannya. Oleh karena itu, tujuan penelitian adalah mengetahui profil kemampuan memecahkan masalah siswa SMP kelas VIII. Metode penelitian adalah deskriptif dengan menggunakan subjek penelitian siswa kelas VIII SMP Negeri Kabupaten Sukabumi yang dipilih berdasarkan purposive sampling. Instrumen  penelitian berupa soal kemampuan memecahkan masalah sebanyak 10 soal uraian dengan 5 indikator (mengidentifikasi masalah, mengumpulkan data, menetapkan hipotesis, menguji hipotesis, dan menarik kesimpulan) pada materi sistem ekskresi. Instrumen pendukung adalah lembar wawancara. Analisis data penelitian dilakukan dengan menghitung capaian rata-rata skor kemampuan memecahkan masalah siswa perindikator dalam bentuk persentase. Hasil penelitian menunjukkan persentase kemampuan memecahkan masalah siswa adalah 40,3% (dikategorikan kurang). Berdasarkan wawancara diketahui bahwa kurangnya kemampuan memecahkan masalah siswa dikarenakan metode pembelajaran yang digunakan belum melatihkan kemampuan memecahkan masalah. Metode pembelajaran yang digunakan adalah ceramah, tanya jawab dan diskusi. Kemampuan memecahkan masalah dapat ditingkatkan dengan cara guru memilih metode pembelajaran yang mampu melatih dan mengembangkan kemampuan ini, yaitu dengan metode praktikum. One of the lessons that emphasizes mastery of skill in the form of problem solving skills is Natural Sciences (IPA). These skills are included in the critical thinking aspect. The characteristics of junior high school (SMP) students who have begun to be able to think critically independently need to develop these skills in the future. Therefore, the study aimed to determine the profile of the problem solving skills of junior high school student in class VIII. The study method was descriptive using the subjects of class VIII students of SMP Negeri Sukabumi who were selected based on purposive sampling. The study instrument was 10 questions in description with 5 indicators (identifying problems, collecting data, establishing hypotheses, testing hypotheses and drawing conclusions) on the excretory system material. The supporting instrument was an interview sheet. Data analysis was carried out by calculating the average achievement score of the indicator student's problem-solving skills in the form of a percentage. The results showed the percentage of students' problem solving skills was 40.3% (categorized as less). Based on the interview, it was known that the students' lack of problem solving skills was due to the learning methods used had not yet practiced problem solving skills. The learning methods used are lectures, question and answer, and discussion. The problem solving skills can be improved by the teacher chooses learning methods that are able to train and develop these skills, one of those is the practicum method.

Abstract

The use of tree thinking in learning biology is still rarely used. The purpose of this study was to identify the tree thinking emergence profile of senior high school students through the inquiry-based learning model. This research is using the experimental method. The approach used in this research is a qualitative approach. The population in this study was 36 students of class X in SMA Negeri Sukabumi. The samples were taken by using a purposive sampling technique. The data collection was performed using a written test in the form of LKS by using five tree thinking indicators. The results showed that the value of tree thinking students for the first indicator gained a percentage of 69% included in the good category, the second indicator obtained a percentage of 63% included in the good category, the third indicator received a percentage of 73% included in the good category, the fourth indicator obtained a percentage of 81% included in the very category good, and the fifth indicator gets a percentage of 52% included in the category enough. This result leads to the Student learning outcomes that are categorized as good because the students follow the learning by using models, strategies, and learning approaches that can improve their ability of tree thinking in Arthropoda subjects. This study suggests that the inquiry-based learning model can be used as an alternative in learning biology to improve tree thinking skills.

Abstract

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.

Abstract

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.
