Abstract

India ink was used to examine the role of the yolk stalk lumen as a distinct pathway between the yolk sac and gut through the first 5 d of post-hatch growth in broiler chicks. Two hundred and sixteen newly hatched broiler chicks were equally divided into three treatment groups; gavaged via the esophagus (TRT1), injected in the yolk sac (TRT2) with 0.2 mL of water-based black India ink and  third group of chicks were used as untreated controls (TRT0). Tissue samples of the small intestine, yolk sac, and yolk stalk were removed and fixed in 10% buffered neutral formalin and were processed routinely, embedded in paraffin, sectioned at 5 to 6 µm, and stained with hematoxylin and eosin. The relative concentration of India ink in each of the tissue preparations was detected with a light microscope and assigned a relative score between 0 and 3, with 0 indicating the lowest and 3 the highest amount of ink present. The results show India ink was able to pass from the yolk sac through the yolk stalk and into the intestine, but was not able to pass from the intestine into the yolk stalk or yolk sac. It was concluded that India ink was useful materials in establishing that the yolk stalk provides a direct one-way passage by which material in the yolk sac may move into the intestine of broiler chicks during the first 5-d after hatching.

Abstract

This study aims to determine the structure of phytoplankton communities in the pool are former coal mining Desa Kampung Baru Kecamatan Cempaka which include abundance, diversity, uniformity and dominance. Phytoplankton samples taken in two pools with a purposive sampling method with a three-point shooting at each pond. Sampling was performed three times. Phylum of phytoplankton were identified in both pools as much as 2 phylum (Chloropyta and Chrysopita) with 17 genera. Average abundance of phytoplankton in the first pool of 7174 ind / liter and 6873 ind / liter in the second pool. The average diversity index of phytoplankton in the first pool of 1.540 and 1.621 in the second pool. Average uniformity index of phytoplankton in the first pool of 0622 and 0.623 in the second pool. The average index of phytoplankton dominance in the first pool of 0271 and 0250 in the second pool. Analysis of community structure (abundance, diversity, uniformity and dominance) shows the condition of the two ponds in the state is quite stable and capable of supporting life inside the phytoplankton. Where the pool in the fertility rate is the level of contamination is, the conditions included in the category of individuals spread more evenly and there are no species that dominate other species in the extreme.

Abstract

Lahan basah merupakan kawasan yang berada didaratan namun terus digenangi oleh air secara permanen maupun hanya musiman. Salah satu tumbuhan yang ditemukan dilahan basah yaitu tumbuhan bamban (Donax canniformis) dan tumbuhan tersebut telah digunakan oleh masyarakat sebagai bahan dasar kerajinan anyaman karena tekstur tumbuhan bamban yang keras dapat menggantikan bahan anyaman yang berasal dari rotan. Penelitian ini akan mengkaji perubahan ukuran pada daun dan batang bamban yang ditemukan didaerah Jejangkit Muara, Kabupaten Barito Kuala. Data dikumpulkan dengan cara mengukur perubahan pada panjang dan lebar daun serta perubahan pada ukuran tinggi batang batang dan diameter batang yang terdapat di tiga lokasi pengambilan sampel, dengan masing-masing ulangan sebanyank 8 kali dengan interval waktu satu minggu. Ketiga lokasi tersebut di atas tersebar di kawasan rawa tadah hujan. Hasil analisis deskriptif menunjukan bahwa adanya perbedaan nilai tengah dan interval dari rerata panjang dan luas daun, serta batang bamban. Penelitian ini menyimpulkan bahwa rerata tertinggi terdapat di lokasi 1 dengan luas daunnya adalah 115,95 cm2, diameter bawah 2,505 cm, diameter tengah 1,94 cm, diameter atas 1,46, tinggi batas 256,5 dan jumlah daun 18,5.

Abstract

Permasalahan dalam usaha pertanaman abaka adalah serangan penyakit layu Fusarium akibat jamur F u s a ri u m o x y s p o r u m .  Varietas yang tahan penyakit tersebut sampai saat ini belum ada.  Perbaikan tanaman terutama sifat ketahanan terhadap penyakit dapat dilakukan melalui peningkatan keragaman somaklonal yang diikuti dengan seleksi i n v itr o . Peningkatan keragaman somaklonal tanaman abaka dilakukan dengan menggunakan mutagen fisik yaitu radiasi sinar gamma dengan dosis radiasi 0, 0,5; 1, 1,5; 2, dan 3 Krad yang dilakukan pada kalus embriogenik.  Semakin tinggi dosis radiasi maka semakin rendah kemampuan kalus untuk beregenerasi. Pada dosis radiasi 3 Krad kalus tidak dapat beregenerasi dan mengalami kematian.  LD50 diperoleh pada kisaran dosis 1-1.5 Krad. Seleksi i n v itr o dilakukan dengan menggunakan filtrat yang diisolasi dari F . o x y s p o r u m melalui dua tahap berurutan, dimana pada seleksi tahap II konsentrasi filtrat dinaikkan satu tingkat dari seleksi tahap I.  Konsentrasi filtrat yang dicobakan adalah 0, 10, 30, dan 50%.  Seleksi tahap I pada tunas yang dihasilkan dari kalus yang telah diradiasi dalam media yang mengandung filtrat menunjukkan semakin tinggi konsentrasi filtrat semakin rendah daya hidup tunas.  Pada seleksi tahap II dimana konsentrasi filtrat ditingkatkan, tunas dari kalus hasil radiasi dapat hidup pada media seleksi.  Pada media seleksi silang yang mengandung 75 ppm asam fusarat, tunas yang tahan filtrat F . o x y s p o r u m tahan juga terhadap asam fusarat.  Perlakuan radiasi dapat meningkatkan persentase daya tahan tunas dalam media seleksi.

Abstract

Dayak Bukit community in Loksado has a long history of usage of various kinds of plants in their daily living, either as food, medicine, or in rituals. In the present study ethnobotanic investigations were performed on jalukap plant (Centella asiatica L) to document the use of the plant by people of Loksado. Botanical study revealed that the plant has simpodial branching, single foliation, indefinite composite inflorescence, composite fruit, and fibrous root. Ethnopharmacological study documented the use of the plant for fish poisoning, as well as for wound and bleeding cough medication. Ethnoanthropologically people use the plant in a ritual against flood disaster. Ethnoeconomic study revealed low economic value of the plant as Loksado people use it only within the community. Ethnolinguistic study documented that the name ‘jalukap’ originated from the form of the leaves which resembles human palm; in Banjarese the word ‘jalukap’ means palm.

Abstract

Lepidoptera is one of the orders of the phylum Arthropoda Insecta class consist of butterflies that are active during the day and moths at night. Both of them belong to the order Lepidoptera and have an important role in the ecosystem. Beneficial role for plants as pollinating insects and  disadvantaged role as pests of cultivated plants. An example is the fall armyworm Spodoptera sp attacking rice plants, Pteroma sp attacks sengon plants, and Helicoverpa armigera attacks red chili plants. One of the efforts to control pests is the use of sex pheromones. Several types of sex pheromones were identified, for example the sex pheromone of the cabbage leaf caterpillar Pluttela xylostella was )-11-hexadecenal, (Z)-11-hexadecenol, and (Z)-11-hexadecenyl acetate with ratio 8:18:100 and 10:1:90. Potato tuber borer (Phthorimaea operculella Zell.) sex pheromones is (E,Z)- 4,7-13 Ac (trans-4, cis-7-tridecadienyl acetate) and (E,Z,Z)-4,7,10-13 Ac (trans-4, cis-7, cis-10-tridecatrienyl acetate) with ratio 1 : 2,5. Using pheromones sex on agricultural land can significantly suppress Lepidoptera pest populations.
