Abstract

This research employed the experimental method with descriptive data analysis. It aimed to isolate and identify sponge symbiont bacteria with antibacterial potential against Multi-Drug Resistance Organisms (MDRO) with the 16S rRNA gene marker. Based on the study results, two sponges were obtained, namely Clathrina sp and Agelas sp, each having 11 and 7 isolates of symbiont bacteria, respectively. Based on the antibacterial activity test results, out of 18 isolates of symbiont bacteria, only 4 had antibacterial potential against MDRO (Klebsiella pneumoniae ESBL, Pseudomonas aeruginosa ESBL, or Staphylococcus lugdunensis MRSA) with inhibition zones of 9.3 mm, 8.3 mm, and 8.1 mm, respectively. The results of bacterial identification using the 16S rRNA gene sequence isolate S1I3, S1I9, and A1I3 belong to the Bacillus cereus and Bacillus paramycoides types. This research is expected to provide important information about sponge symbiont bacteria with antibacterial potential against MDRO.

Abstract

Pemanfaatan tumbuhan obat sebagai bagian dari pengobatan tradisional telah lama menjadi warisan budaya yang melekat dalam kehidupan masyarakat Indonesia. Namun, di era modern ini, pengetahuan dan pemanfaatan tanaman obat cenderung menurun seiring dengan meningkatnya ketergantungan pada obat-obatan kimia . Masalah yang dihadapi mitra adalah banyak masyarakat lokal yang tidak sepenuhnya memahami nilai ekonomi dari tumbuhan obat yang tersedia di sekitar mereka, pemanfaatan tumbuhan obat masih didominasi oleh cara tradisional tanpa pengolahan lebih lanjut yang bernilai tambah. Kegiatan PKM FMIPA UNIMED ini bertujuan untuk mendorong pemanfaatan tumbuhan obat lokal sebagai produk bernilai ekonomi untuk meningkatkan kesejahteraan masyarakat. Kegiatan PKM ini dilakukan dengan kelompok masyarakat “Minyak Karo Mulawari” yang produktif di bidang obat tradisional di desa mulawari, Tigapanah, Kabupaten Karo. Hasil pelaksanaan PKM terdapat peningkatan pengetahuan peserta tentang manfaat tumbuhan obat, Teknologi Tepat Guna sehingga kelompok mitra dapat mengoptimalkan produksi pemanfaatan tumbuhan obat lokal sebagai pengobatan tradisional di era modern yang memiliki peningkatan nilai jual. Hasil penilaian peserta terhadap keterlaksanaan kegiatan PKM menunjukkan tingkat kepuasan yang tinggi dan memberikan dampak positif bagi mitra untuk mengembangkan pengelolaan dan peningkatan usaha minyak karo di desa mulawari, Tigapanah, Kabupaten Karo.

Abstract

This study aims to describe local plant species used as traditional medicine by communities in North Sumatra. The research method employed in-depth interviews with communities in three locations including Karo, Medan and Simalungun. The research results identified 81 species of local medicinal plants from 39 botanical families, with the Zingiberaceae family dominating (13 species, 16.05%), followed by Asteraceae (7 species, 8.64%), Piperaceae and Fabaceae (5 species each, 6.17%). Ginger (Zingiber officinale) was the most commonly used plant across three different locations. The most utilized plant parts were leaves (48.15%), rhizomes (22.22%), and fruits (13.58%). The primary processing methods were boiling (40.7%) and pounding (22.2%). This study demonstrates that North Sumatran communities possess diverse traditional knowledge in utilizing local medicinal plants that needs to be documented and preserved.

Abstract

Penelitian ini bertujuan untuk mengetahui model pemeblajaran group investigation (GI) terhadap keterampilanproses sains siswa kelas XI MIA di SMA Negeri 5 Medan pada tahun pembelajaran 2015/2016 pada praktikumsystem eksresi pada manusia. Penelitian ini merupakan penelitian eksperimen , dengan penyajian data deskriptif.Sampel yang digunakan adalah kelas XI MIA 5 sebagai kelas eksperimen dan XI MIA 6 sebagai kelas control.Pengambilan sampel menggunakan tehnik random sampling. Variabel bebas dalam penelitian ini yaitu modelpembelajaran Group Investigation (GI) sedangkan variabel terikatnya adalah keterampilan proses sains siswa.keterampilan proses sains siswa di lihat dari 9 keterampilan, yaitu keterampilan membuat pertanyaan,keterampilan merumuskan hipotesis, keterampilan merencanakan percobaan, keterampilan menggunakan alatdan bahan, keterampilan melakuakan observasi, keterampilan menginterpretasikan data pengamatan,keterampilan mengklasifikasikan hasil pembahasan, keterampilan menerapkan konsep dan keterampilanmengkomunikasikan. Berdasarkan hasil observasi menggunakan rubrik penilaian diperoleh skor keterampilanproses sains siswa yang diajar dengan menggunakan model Group Investigation (GI) lebih tinggi dibandingkandengan siswa yang diajar dengan menggunakan pembelajaran langsung (84,33 > 67,52). Berdasarkan hasil tersebutdapat disimpulkan bahwa model pembelajaran Group Investigation (GI) berpengaruh terhadap keterampilanproses sains siswa.Kata kunci : Group Investigation, Keterampilan Proses Sains, Sistem eksresi

Abstract

Biology learning on ecosystem material still faces various obstacles, particularly the limited use of interactive learning media, which affects student engagement and learning outcomes. This study aimed to develop Genially-based interactive learning media oriented to the Salingtemas (Science, Environment, Technology, and Society) approach on ecosystem material that meets the criteria of validity, practicality, and effectiveness. This research employed the Research and Development (R&D) method using the ADDIE model, covering the Analysis, Design, Development, Implementation, and Evaluation stages. The study was conducted at SMA Negeri 1 Percut Sei Tuan involving 36 students of class X-4. Data were collected through expert validation sheets, teacher and student response questionnaires, and pretest-posttest instruments, then analyzed descriptively along with the Paired Sample t-test and N-Gain analysis. The results showed validation scores of 87.5% from material experts, 92.2% from media experts, and 89.0% from language experts, all in the highly valid category. The practicality test yielded 95.71% from teachers and 86.19%-86.67% from students across the trial stages, categorized as highly practical. The pretest mean increased from 48.69 to 87.75 on the posttest, with a Paired Sample t-test significance of 0.000 (<0.05) and an N-Gain of 0.7548 (high category). The developed media is therefore valid, highly practical, and effective for supporting Biology learning on ecosystem material.
