Abstract

Basic Biology subjects are integrated between theory and practicum. Practical learning is an essential way that teachers can take to improve students' science process skills, so a valid instrument is needed to measure it. The objective of this study is to produce a valid performance assessment instrument in practical learning; a student worksheet in practical learning; the improvement of science process skills; and teacher response. The type of research is referring to model of 4-D. The subject of research is composed of the students in the odd semester academic year 2021-2022 at SMA Muhammadiyah Langsa. Instruments of research consist of validation sheet, student worksheet, observation sheet, questionnaire. The findings show validity score is 84% (good category); student worksheet in practical learning is 43% (very good category); there is the improvement of students science process skills before and after the practical learning, which shows by N-gain value of 0.64% (high category); and teacher response to developed performance assessment instrument is 83% (very practical category).

Abstract

Kelas Biologi yang baik selalu dimulai dari pertanyaan yang membangkitkan rasa ingin tahu dan menstimulasi siswa berpikir, oleh karena itu kemampuan mengajukan pertanyaan yang berkualitas adalah elemen yang wajib dikuasai oleh seorang pendidik. Penelitian ini bertujuan untuk mendiagnostik profil kualitas pertanyaan mahasiswa calon guru Pendidikan Biologi Universitas Samudra dalam konteks High Order Thinking Skills (HOTS) sehingga dapat memberi masukan bagi perbaikan dan peningkatan keterampilan dasar mengajar mahasiswa calon guru, khususnya keterampilan bertanya. Subjek penelitian terdiri dari 48 mahasiswa  yang mengambil mata kuliah Bioteknologi di semester 4 dan belum mendapatkan mata kuliah microteaching. Metode dalam penelitian ini adalah metode deskriptif kualitatif.  Tehnik pengumpulan data dilakukan dengan mendokumentasikan pertanyaan-pertanyaan yang diajukan mahasiswa calon guru dalam mata kuliah Bioteknologi yang berjumlah  164 pertanyaan. Analisis data kualitas pertanyaan menggunakan instrument matriks taksonomi Bloom edisi revisi Anderson dan Karthwohl. Hasil penelitian menunjukkan bahwa 80% pertanyaan masih berada dalam level Low Order Thinking Skills (LOTS) dengan akumulasi C1 26%, C2 38%, dan C3 16%. Sementara 20% pertanyaan tergolong dalam High Order Thinking Skills (HOTS) dengan akumulasi C4 19% dan C5 1%.

Abstract

Desa sukaramai Dua berada terletak pada kabupaten Aceh Tamiang kecamatan sernway, daerah Kecamatan  Seruway pada kampung  Sukaramai Dua ini merupakan  kawasan pinggiran yang memiliki jumlah penduduk pada tahun 2018 berjumlah 2.776 jiwa dan 828 Kepala keluarga. Selain berternak sapi masyarakat sukarami dua juga memiliki komoditi perternakan ikan nila Oreochromis niloticus. Ikan nila Oreochromis nilaticus  adalah salah satu ikan air tawar yang banyak dibudidayakan karena mudah beradaptasi dengan lingkungan yang kurang menguntungkan dan mudah dipijahkan, sehingga penyebarannya di alam sangat luas. Kandungan gizi pada ikan nila sangat lengkap. Ikan nila ini mempunyai kandungan protein yang sangat banyak namun rendah lemak dan kalorinya. Berdasarkan permasalahan yang dihadapi mitra dari kesepakatan tim pengabdian Kepada Masyarakat solusi yang ditawarkan adalah (1) Sosialisasi aplikasi Branhionus Plicatilis pada Larva Nila Nila Oreochromis Niloticus pada Kelompok mekar Jaya Desa Sukaramai Dua Kabupaten Aceh Tamiang (2) Pelatihan teknik mengkultur pakan alami makanan ikan nila. Metode pelaksanaan kegiatan meliputi empat tahapan utama, yaitu survey lapangan, tahap dua sosialisasi, tahap tiga pelatihan, dan tahap empat pendampingan untuk memonitoring, serta mengevaluasi perkembangan hasil kegiatan untuk keberlanjutan program PKM di desa tersebut. Sehingga diharapkanaplikasi Branhionus Plicatilis pada Larva Nila Nila Oreochromis Niloticus.Hasil yang diharapkan adalah Masyarakat Petani Mekar Jaya dapat mengembang biakkan bibit larva untuk digunakan sebagai pakan ikan nila.

Abstract

Paphiopedilum primulinum is one of endemic orchids in Gayo, Aceh, Indonesia. This terrestrial orchid is registered as endangered species due to IUCN. The low availability of this orchids in nature is due to habitat lost, over-collection for commercial purpose, and low seed germination rate which affected by unidentified factors, yet the study of propagating this orchid is rarely discussed. This experimental research is aim to see the effect of coconut water (CW) concentration to P. primulinum seed germination and development through in vitro culture. The sample of the study used the seed of P. primulinum which age 14 weeks after pollination. The research use ½ Murashige and Skoog media (MS) with four different coconut water (CW) concentration (0,10%, 20%, 30%) and incubated for 90 days. The seed germination rate is calculated due to the percentage of its total germinate seed and seed development indicator divided into 5 stages (0-5). The result shows that the seed of Paphiopedilum primulinum germinate best at 30% CW concentration and only in this concentration the seedling stage reach stage 5 (4.8%). This result implies that 30% CW concentration in ½ MS medium is the best medium to germinate this seed.
