PENGARUH EKSTRAK PEDADA MERAH (Sonneratia careolaris L.) TERHADAP JUMLAH DAN MORFOLOGI SPERMATOZOA MENCIT (Mus musculus L.)
Jurnal Bioconcetta Vol 6, No 1 (2020): Sinta 4
Publisher : Universitas PGRI Sumatera Barat

Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak Pedada Merah (Sonneratia careolaris L.) terhadap jumlah dan morfologi spermatozoa mencit (Mus musculus L.). Penelitian ini adalah penelitian eksperimen dengan menggunakan rancangan acak lengkap (RAL). Pemberian ekstrak Pedada Merah diberikan secara oral selama 36 hari terhadap 24 ekor mencit jantan dewasa dengan 6 perlakuan dan 4 ulangan. Hasil penelitian menunjukkan pemberian ekstrak Pedada Merah dapat menurunkan jumlah sperma mulai dari perlakuan P3 dengan jumlah 7,75x105 sperma/mL, perlakuan P4 dengan jumlah 7,25x105 sperma/mL, P5 dengan jumlah 6x105 sperma/mL dan P6 dengan jumlah 5,12x105 sperma/mL. Morfologi spermatozoa mencit jantan mulai dipengaruhi dari perlakukan P3 dengan ditemukannya bentuk sperma abnormal berupa ekor yang patah dan bergulung serta kepala putus. Penelitian ini menunjukkan bahwa pemberian ekstrak Pedada Merah dapat menurunkan jumlah spermatozoa dan mempengaruhi morfologi sperma mencit.

Publisher : Universitas PGRI Sumatera Barat

The result of research interviews with biology teacher at SMPN 2 Sungai Limau, Padang- Pariaman district revealed that, when the teacher explains the material in human digestive system, teachers only explain lessons using media board. Though these materials, demanding to know the structure of the digestive organs and the digestive process. In addition, the average value of students for the material is still below 65, while KKM. The KKM is 77. So that the material presented by the teacher cannot be understood by the students well. Besides this, materials contained in these schools is not sufficient for the number of pupils and students only have worksheets that are not in accordance with the applicable curriculum. The purpose of this study is to look at the validity of the media images with applications movie maker in human digestive system materials for junior level. This research is development research and the data processed by descriptive statistik. Results of this study was to test the validity of media images with applications movie maker in human digestive system materials for junior high school is very valid with the average of 89.75%. And concluded that the validity of the media image with movie maker app on the human digestive system materials for junior high schools categorized as very valid with a average is 89.75%.

Publisher : Universitas PGRI Sumatera Barat

Sumatera adalah pulau terbesar ketiga di Indonesia dengan iklim tropis dan keanekaragaman ular yang tinggi. 127 jenis ular telah tercatat di Sumatra. Informasi taksonomi dan distribusi ular masih sedikit terutama di provinsi Sumatera Barat. Salah satu ular endemik yang terdapat di Sumatera Barat adalah Trimeresurus barati. Tidak ada informasi yang jelas entang keberadaan ular ini. Informasi tersebut dibutuhkan untuk mengenali keberadaan herpetofauna khususnya Trimeresurus barati yang merupakan hewan endemik Sumatera Barat, dimana selanjutnya bertujuan untuk upaya konservasi. Penelitian telah dilakukan pada bulan Februari 2015 hingga Agustus 2015 dengan menggunakan metode survei, termasuk koleksi langsung pada beberapa daerah di Sumatera Barat, pengumpulan informasi dari masyarakat dan identifikasi spesimen yang telah ada di Laboratorium Zoologi STKIP PGRI Sumatera Barat. Berdasarkan penelitian ini, telah ditemukan T.barati dibeberapa tempat yaitu di daerah Paninjauan sebanyak 4 spesimen, Balingka sebanyak 3 spesimen, Matur sebanyak satu spesimen, Batipuh sebanyak 2 spesimen, Sabu sebanyak 1 spesimen, Andalehsebanyak 1 spesimen, CA Lembah Anai sebanyak 5 spesimen, Tambangan sebanyak 4 spesimen dan Alahan Panjang sebanyak 3 spesimen. Umumnya T.barati ditemukan pada daerah berketinggian 600-1000mdpl dengan suhu berkisar 12C-28C
