Abstract

The aim of this study was to assess the percentage of local duck spermatozoa morphology (Anas platyrhynchos) for 6 days of storage in three storage mediums combining various egg yolk (EY) concentrations.This experimental study applied three combinations of factors as treatment. Medium (Tris, PBS or Ringer lactate), egg yolk (EY) concentration 0,5,10,15 or 25% and storage time (0,1,2,3,4,5,6 day). Spermatozoa obtained by sequence method, ejaculate or sperm obtained in swim up in medium, swim up spermatozoa were used for treatment in storage medium according to treatment and assessed before and after morphology of storage in refrigerator temperature (50 C). The results showed that spermatoza morphology was significantly different (P <0.01) between 15 treatments. The medium factor and concentration of EY significantly (P <0.05) affected the morphology of treatment spermatozoa. The highest percentage of highest post-preservation spermatozoa morphology for six days was obtained in 5% yolk treatment in PBS medium (5EYPBS). This study proves that egg yolk cryoprotectants are good for maintaining the morphology of local duck spermatozoa.

Abstract

Berpikir kritis adalah kemampuan menalar seseorang dalam menilai, memecahkan masalah, dan mengambil keputusan ilmiah. Berpikir kritis merupakan salah satu aspek yang dibutuhkan dalam implementasi Kurikulum 2013 dan mampu meningkatkan pemahaman peserta didik terhadap materi yang dipelajari. Untuk meningkatkan kemampuan berpikir kritis peserta didik dapat digunakan model Problem Based Learning dan Discovery Learning. Hasil observasi peneliti menunjukkan bahwa di SMPN 5 Panyabungan belum menerapkan penilaian kemampuan berpikir kritis siswa dan cenderung menggunakan model pembelajaran yang monoton sehingga minat peserta didik dalam mengikuti kagiatan belajar masih rendah, yang dimana tergambar dari nilai rata-rata ujian akhir peserta didik. penelitian ini bertujuan untuk membandingkan kemampuan berpikir kritis peserta didik yang diajar dengan menggunakan model Problem Based Learning dan Discovery Learning. Penelitian ini merupakan penelitian eksperimen dengan rancangan penelitian The Statistic Group Comparison yang dimodifikasi karena tidak menggunakan kelas kontrol, tetapi menggunakan dua kelas sampel yaitu Kelas Eksperimen I dan Kelas Eksperimen II. Pemilihan sampel dilakukan dengan purposive sampling sebanyak dua kelas berdasarkan selisih nilai rata-rata terkecil. Kelas Eksperimen I dan Kelas Eksperimen II ditentukan secara acak. Kemudian diperoleh VIII1 sebagai Kelas Eksperimen I dan VIII2 sebagai Kelas Eksperimen II. Hasil penelitian menunjukkan bahwa terdapat perbandingan kemampuan berpikir kritis peserta didik yang diajar dengan model Problem Based Learning dan Discovery Learning. Kelas Eksperimen I yang menggunakan model Problem Based Learning memiliki nilai rata-rata 77,9 dan Kelas Eksperimen II yang menggunakan model Discovery Learning memiliki nilai rata-rata 63,3.

Abstract

Kemampuan berpikir tingkat tinggi adalah kemampuan yang mencakup tiga aspek yaitu analisis, evaluasi dan penciptaan sesuai dengan implementasi kurikulum 2013. Berdasarkan pengamatan pra-penelitian yang dilakukan di SMAN 2 Koto XI Tarusan diperoleh bahwa instrumen yang digunakan oleh guru masih pada level kognitif C1-C3 dengan persentase C1 56%, C2 40%, dan C3 4%, sedangkan untuk tuntutan kemampuan berpikir level Siswa yang lebih tinggi harus mampu berpikir pada level kognitif C4-C6. Penelitian ini bertujuan untuk  menghasilkan instrumen penilaian kemampuan berpikir tingkat tinggi tentang materi sistem pencernaan  dengan menggunakan model 4D  models. Subjek penelitian dua orang dosen biologi FMIPA UNP sebagai validator dengan rata-rata hasil validasi instrumen penilaian sebesar 78,82% dengan kriteria cukup valid. Ini menunjukkan instrumen penilaian kemampuan berpikir tingkat tinggi tentang materi sistem pencernaan cukup valid dikembangkan dari segi materi, konstruksi, bahasa serta tingkat kognitif instrumen penilaian kemampuan berpikir tingkat tinggi sehingga dapat digunakan untuk mengukur kemampuan berpikir tingkat tinggi peserta didik tentang materi sistem pencernaan.

Abstract

Sweet potato varieties (Ipomoea batatas) Pucuk Hitam Panyalaian and Madu Pucuk Hitam Panyalaian have the potential to be a superior commodity in West Sumatra, but the information of genetic diversity is very limited. Data on the diversity of sweet potato germplasm is beneficial in the selection of plants to obtain superior cultivars in plant breeding. Aim: The aim of the study was to find specific primers for the study of sweet potato genetic markers using Ipomoea batatas chloroplast genes matK. Methods: DNA extraction from sweet potato young leaves; designing forward and reverse primers Ipomoea batatas chloroplast genes matK; PCR; sequencing; bioinformatics analysis and species identification by comparing the NCBI database. Results: Plant DNA barcoding PCR using designed primers matK were successfully resulting single DNA band in different amplicon size in some samples. This indicating that the designed primers used were able to distinguish variation in one species.
