KARAKTERISTIK MORFOMETRIK DAN HABITAT KIJING TAIWAN (Sinanodonta woodiana) DI ALIRAN IRIGASI DESA SAMBORA KECAMATAN TOHO KABUPATEN MEMPAWAH
No full textSinanodonta woodiana is known as kijing taiwan which is mostly found in the irrigation flow of the village of Sambora Toho District Mempawah Distric. However, its existence is now experiencing a decline. For this reason, management is needed that requires data on morphometric and habitat characteristics. Therefore the purpose of this study was to determine the morphometric characteristics and habitat characteristics of S. woodiana in the irrigation flow of Sambora Village, Toho District, Mempawah Regency. The research method used was Purposive Random Sampling, using three different observation stations, namely station 1 is in the upstream part of the irrigation area close to a waterfall of oil palm plantations and freshwater fish cultivation ponds, station 2 is in an area adjacent to freshwater fish cultivation ponds and settlements, and station 3 is in a downstream area close to factory waste disposal tofu, freshwater fish farming ponds, and oil palm plantations.This research was conducted in March - May 2020 in the irrigation flow of Sambora Village, Toho District, Mempawah Regency. Based on the results of the study, there were 565 individuals of S. woodiana. All characters of mean shell length (PC), shell height (TC), shell thickness (TBL), and total weight (BT) show that the size varies between male and female sex, the female sex is greater than the male sex. The density values ranged from 0.37 to 3.02ind / m2. The density between stations is different and the highest is at station I and the lowest is at station III.

No full textKalimantan Barat merupakan salah satu daerah yang memiliki keragaman padi merah yang cukup tinggi. Penelitian ini bertujuan untuk mengkarakterisasi identitas padi merah variets Maiyan secara morfologi dan molekuler. Penelitian dilakukan berdasarkan dua tahapan yaitu identifikasi morfologi daun, batang, bulir dari padi dan identifikasi molekuler dengan menggunakan penanda gen MatK. Hasil penelitian menunjukkan bahwa Padi Merah Varietas Maiyan berdasarkan pengamatan morfologi yaitu jumlah anakan 1-13 buah, dengan anakan produktif 1-11 buah, warna permukaan daun hijau kekuningan (Green Group 144C), jumlah nodus 5. Padi Merah Maiyan memiliki tinggi tanaman yang cukup besar yaitu mencapai 122,5-149,5 cm. Hasil identifikasi molekuler Padi Merah Maiyan memiliki kemiripan dengan Oryza sativa Japonica cultivar Nipponbare 99%, Oryza sativa Japonica Group bio-material IRGC33984 99%, Oryza sativa Rufipogon 99%, Oryza sativa cultivar Giza 178 99%, dan Oryza sativa cultivar NARC 17958 99%. Kemiripan yang tinggi diduga dipengaruhi oleh asal tetua dari Padi Merah Varietas Maiyan yang sama dengan kelima padi tersebut. Kata Kunci : rice, characterization, MatK, molecullar, morphology
