Pengaruh minuman beralkohol terhadap fungsi spermatogenik testis mencit jantan (Mus musculus L.)
Full text linkMinuman beralkohol merupakan salah satu produk minuman yang sudah menyebar luas dan sudah banyak dikenal di seluruh dunia. Alkohol yang terdapat dalam minuman dapat menyebabkan toksisitas pada manusia khususnya pada organ reproduksi.
Penelitian ini menggunakan Rancangan Acak Lengkap dengan 4 perlakuan dan 3 ulangan. Masing-masing diberi minuman beralkohol dengan dosis 0,2 ml/ekor untuk P1, 03 ml/ekor untuk P2 dan 0,4 ml/ekor untuk p3. Parameter yang digunakan meliputi panjang testis, diameter testis, indeks testis dan indeks spermatogenesis. Data yang diperoleh dianalisis dengan ANOVA dan apabila terdapat perbedaan yang berarti dilanjutkan dengan uji LSD (Least Significant Difference).
Dari hasil penelitian menunjukkan bahwa pemberian minuman beralkohol pada mencit jantan dapat menurunkan panjang testis, diameter testis dan indeks testis serta indeks spermatogenesis testis secara signifikan
Potensi Nilai-nilai Karakter Mahasiswa Multietnis Dalam Mempengaruhi Keterampilan Berpikir Kritis Pada Pembelajaran Biologi
Full text linkMenghadapi perkembangan ilmu dan teknologi (IPTEK), diperlukan kualitas sumber daya manusia. Cirimanusia yang berkualitas adalah memiliki keterampilan berpikir kritis. Rendahnya keterampilan berpikirkritis dapat disebabkan karena proses pembelajaran yang kurang menanamkan nilai-nilai karakter padamahasiswa yang memiliki latar belakang multietnis. Nilai-nilai karakter dari setiap etnis memiliki potensidalam mempengaruhi keterampilan berpikir kritis seseorang. Kajian dalam tulisan ini mengungkap potensinilai-nilai karakter pada mahasiswa multietnis dalam mempengaruhi keterampilan berpikir kritis biologi.Adapun etnis yang dikaji meliputi etnis Dayak, Melayu, dan Jawa. Berbagai kajian literatur mendeskripsikanbahwa ketiga etnis tersebut memiliki nilai-nilai karakter yang berpotensi dalam mempengaruhi keterampilanberpikir kritis mahasiswa biologi. Adanya potensi dari nilai-nilai karakter pada mahasiswa multietnis,mendorong dosen untuk menerapkan berbagai strategi pembelajaran yang bernuansa pendidikan karakter,salah satunya adalah strategi pembelajaran Jigsaw, Reading, Questioning, Answering (JiRQA)

Diversity of Annelids in the Kapuas and Melawi Rivers
Full text linkThe presence of Annelida animals in water is one indicator of polluted water. The purpose of this research was to determine the diversity of Annelida phylum in the Kapuas and Melawi rivers. This research used an exploratory method to determine the diversity of annelids in the Kapuas and Melawi rivers. Sampling was carried out in 2 regions representing the left and right sides of the river, both upstream and downstream of the river. The findings of the research show that there are two classes of annelid phyla, namely the Oligochaeta and Hirudinae classes. Oligochaeta class is represented by Tubifex sp, Lumbricus terrestris, and Pharetima sp. species while Hirudinae class is represented by Haemodipsa sp. Species. The number of Annelids found in the Kapuas river for Tubifex sp. numbered 7 species, Lumbricus terrestris numbered 53 species and Pharetima sp. numbered 14 species. The number of Annelids found in the Melawi river for Tubifex sp. numbered 1 species, Lumbricus terrestris numbered 23 species, Pharetima sp. numbered 8 species and Haemodipsa sp amounted to 2 species. The presence of Tubifex sp. in the Kapuas and Melawi rivers shows that the quality of the river waters begins to be polluted
