Abstract

Fern is a vascular plant wich classified to the low level plants. Polypodiaceae is family of ferns with high diversity in the world. Ferns have sporophytes and gametophytes generation independently. In addition to morphology os sphorophytes, morphology’s gametophytes of ferns in form spores and prothallium also have potential diversity.of characters. That diversity need to be done research to identify the profile of spores dan prothallium characteristic of ferns in the Polypodiaceae family. The aim of this research is to identify the profile of spores dan prothallium characteristic of ferns in the Polypodiaceae family. The research method is conducted in stage: 1) takeing sample of 10 species Polypodiaceae family of ferns. These species is Adiantum caudatum, Asplenium nidus,Athyrium sp, Dryopteris concolor, Nephrolepis falcata, Phymatodes longissima, Pityrogramma calomelanos, Platycerium bifurcatum, Pteris ensiformis, Pyrrosia sp, 2) planting spores to produce prothallium, 3) observe the morphological spores and prothallium. Result of this research shows that spores of 10 species were observed have various form, that is include: ovatus, elipticus, reniformis, triangularis and serial irregular. Variety of surface ornamentation spores include: retiformis foveatus, granulosus, ruminatus, verruculosus, colliculotus, areolatus, and glabber. Prothallium of these species have elongated cordata and widened cordata shapes. The difference is showed on the edge of prothallium and the presence of additional part likes papila and trichomes on its surface. The layout of the anteredia of Platycerium bifurcatum and Pyrrosia sp is different from the others, which is located on the edge of the surface prothallium. The archegonia of all species is located near the notch of prothallium. Diversity characters of spores and prothallium can be use to classification and analysis of realationship of fern. Key words: Ferns, spore, prothallium, character, diversity

Abstract

Aedes aegypti mosquito which is the main vector of the disease Dengue Hemorrhagic Fever (DHF) and Yellow Fever / Chikungunya. As a result of transovarial transmission of dengue virus within the body of the female mosquito Aedes aegypti into the eggs. The eggs hatch into larvae when already having dengue virus in his body without having to suck the blood of patients with DHF. Population density of Aedes aegypti larvae measured by the density and number of containers is very real impact on cases of dengue transmission. Two factors related to the presence and density of larvae itself include sociodemographic and environmental factors, both of which interact with each other. This study aims to determine the influence of sociodemographic and environmental factors on the population density of Aedes aegypti mosquito larvae in the Village Benculuk and to know the dominant factor causing population density of Aedes aegypti mosquito larvae. The design of the study design using qualitative methods. The results of the study showed the influence of the level of knowledge and behavior with the density of mosquito larvae of Aedes aegypti in the Village Benculuk, Banyuwangi. The influence of the distance between houses, the presence of water reservoirs and fish-eating larvae of the Aedes aegypti mosquito larvae density in the Village Benculuk, Banyuwangi. Environmental factors that affect population density dominates the mosquito Aedes aegypti larvae in the Village Benculuk, Banyuwangi. Keywords: sociodemographic, environmental, and Aedes aegypti.

Abstract

Earthworm (Pheretima javanica K.) is a common soil biofertilizer. This repulsive animal for some has been widely used for remedial medicine as well. Simplicia being used in this study was obtained from dried and blended earthworm along with its intact internal organs. The aim of the study was to determine the toxicity effect of earthworms powder to renal histopathology in rats (Rattus norvegicus). A total of 50 rats were divided into five groups consisting of a negative control group (2 ml 1% CMC Na), P1 earthworms group at dose of 0.4 grams, P2 earthworms groups at dose of 0.8 grams, P3 earthworms group at a dose of 1.6 grams, and P4 earthworms group at a dose of 3.2 grams. The rats were acclimated for about a week, then orally induced by earthworm powder. The treatments were conducted for 14 consecutive days to see any toxic symptoms developed. ANOVA results showed the administration of earthworm (Pheretima javanica K.) powder did not significantly affect renal physiology and histopathology. There was no damage observed microscopically. Keywords: Pheretima javanica K. powder, Rattus norvegicus B., renal histopathology.

Abstract

Nutrients are needed by plants for the growth process and development. One crucial nutrient is nitrogen. Nitrogen triggers the formation and growth of vegetative parts of plants such as roots,stems and leaves. This study aimed to determine the effect of nitrogen dose against Glicine max. L strains UM.4-1, strains UM.7-2, strain UM.2-4, strains UM.7-6, strain UM.6-2, and two varieties namely Gumitir and Wilis resistant Bemisia tabaci. This experimental research was using a completely randomized block design with 4 treatment doses of nitrogen, 0 g, 25 g, 75 g and 100 g/polybag combined with 0,55g of potassium and phosphate 0,917g/polybag. The variables measured were length of petioles, the leaf ratio, leaf length, width and leaf area. Observations was carried out based on soybean lines, dosage, and a combination of both. Data were analyzed using 2-way ANOVA. The results showed that there were significant different in the lenght of petiole, leaf ratio, leaf length, width and leaf area on different strains of Glicine max. L. There was also the effect of different treatments (doses) on the length of petiole, leaf ratio, leaf width and leaf area but no significant effect on leaf length. Combination of treatments showing there were effect on the length of petiole, leaf ratio, leaf length and width and also on leaf area. Keywords: Nitrogen, morphologycal character, Glicine max.L.

Abstract

Grayak caterpillar is insect pests that become pests of various food crops. Grayak caterpillars cause a decrease in crop productivity and even crop failure if they are not controlled. Pest control using chemical pesticides has many adverse effects on the environment. To minimize the occurrence of environmental damage, then it is used pest control using vegetable insecticides. Bintaro Leaf (Cerbera odollam Gaertn.) is potential as a vegetable insecticide. The purpose of this study was to examine the toxicity of granule from Bintaro leaf extract (C. odollam Gaertn.) on armyworms (S. litura Fab.). This research was a laboratory experimental research using Completely Randomized Design (CRD). Serial concentrations used in this study were 0% (control), 0.5%, 1%, 1.5%, 2%, and 2.5%. The results of this study showed that the granules of Bintaro leaf extract (C. odollam Gaertn.) were effective in causing mortality of armyworms (S. litura Fab.) at 1.5% concentration by 60% and included in toxic category. The value of LC50-48 hour granule from Bintaro leaf extract (C. odollam Gaertn) was 1.41%. Keywords: Spodoptera litura Fab. , Granula extract of Cerbera odollam Gaertn., Vegetable Insecticide.
