Abstract

NPV is one of the biological insecticides that kills the target by infecting their cells including hemocytes. Hemocytes play a key role on defence mechanism against pathogens like NPV. This defense mechanism may cause the insect to become more tolerant as well as to chemical insectisides. The tolerances of insect to NPV could be induced by cellular immune system (CIS). One of the CIS is capsules/nodules formation. Based on that assumption, this research was conducted to observe the alteration of capsules/nodules formation of Helicoverpa armigera larvae post sublethal infection of HaNPV (Helicoverpa armigera nuclear polyhedrosis viruses). The fifth instar Helicoverpa armigera ware infected by sublethal doses of HaNPV. 24 hour post infection, partly of survive larvae reared to get their first (NPV-F1) and second filial (NPV-F2). Another survivor induced by hit killed Bacillus cereus, and then its haemocoel were exposed under stereo microscope (total magnification, 60 X) to watch capsules/nodules that appear as black spots on haemolymph. This procedure also conducted to fifth instar larvae of NPV-F1, NPV-F2, control (K-P) and their filial (K-F1 and K-F2), blank and placebo. The result showed that the number of nodules/capsules on larvae were not significant between control and the NPV-treat larvae on every generation, which was about 4 nodules/capsules. It showed that there is no cellular immune respon changed on NPV-P larvae, so their immune ability are similar to larvae K-P. The recoveries of NPV-P larvae cause it have a good capability to produce offspring with good immune response. So, NPV-F1 and NPV-F2 larvae have same ability as K-F1 and K-F2 larvae. It can be concluded that the use of sublethal dosage of HaNPV has not changed formation of capsules/nodules of H. armigera larvae and their offspring.

Abstract

In Indonesia, the high growth of population is special problem.  Because of that, the government had to done something to holding the rate population problem, that one of them is Planning Family (KB) in national program.  Increased of rate acceptor KB can give effect to contraception logistic crisis, so it can be decreased logistic supply.  By the way, the development of contraception from plant is one of alternative that can do it. Indonesia is tropical country that have richness flora.  More than 940 species that has planting and used be herbal medicine or traditional medicine and from 75th family are more than 225th plant species that used be contraception material.  One of them is sea grass (Enhalus acoroides) because it?s contained steroid, that?s can be isolated from all of body plant, like roots, rhizome, and leaf.  Fitosterol on leaf sea grass is very potential that it had to explore in biology aspect.  It?s very important in supply steroid, to be contraception material and or medicine. This research aimed to knows the influence fitosterol of sea grass (Enhalus acoroides) to fertility of Mencit (Mus musculus) male ICR.  There are four experiments (A0= control : just give it to mencit is suspension of fitosterol sea grass and A1, A2, A3 : give it to mencit  is dose of fitosterol sea grass with each experiment are 25, 50 and 75 mg/kg per mencit).  Rate of mencit in experiment are 60 mencit. The parameter of research are heavy of testis, epididimis and vesikula seminalis, rate and sperm mortality, and so conception from male mencit. Based on the results of that research has been done shows that the fitosterol of sea grass is making influence to mencit, like increasing of heavy of testis, epididimis and vesikula seminalis, and mortality of mencit.  But it can decrease of sperm rate and conception of mencit.  It?s meaning that the higher dose of fitosterol can make lower of result.

Abstract

This study is an experiment, consisting of two stages. The first stage aims to find a ways of processing umbi gadung (Dioscorea hispida Dennst) against level of  HCN; and second phase aims to determine the effect of fermentation by Ragi tape on the concentration of glucose in umbi gadung. Variable in the first stage of research consisted of two types, namely the independent variables such as processing methods and the dependent variable concentration of cyanide in umbi gadung.  This research using Completely Randomized Design (CRD), consisting of three treatments and one control, comprised of three replications., Namely: Ao: umbi gadung  without treatment (control); A1: umbi gadung  are boiled; A2: umbi gadung  which soaked with salt and A3: umbi gadung  to be smeared with ash wood. The second stage consists of variables, independent variable is the length of fermentation by ragi tape and the dependent variable glucose concentration umbi gadung  flour (Disocorea hispida Dennst). Design used in the study were Completely Randomized Design (CRD), which consists of three treatment groups and one control three repetitions, so there are 12 units of experimental treatments. Each of these treatments are: Po: Flour without fermented umbi gadung  ; P1: umbi gadung  flour is fermented for 72 jam. Test of  glucose concentration with Anthrones yam method. Testing is done in two stages: for 24 hours; P2: umbi gadung  flour is fermented for 48 hours; and P3: umbi gadung  flour fermented first, to determine the effect of umbi gadung  processing methods on the concentration of HCN, to obtain low concentration of tuber and the second HCN: the effect of ragi  tape length of fermentation  of glucose concentration on umbi gadung  low concentration of HCN. Data obtained were analyzed by analysis of variance Fα = 0.05 and followed by LSD α = 0.05. The observation indicates that the first stage of processing methods significantly affected the concentration of HCN, the results of LSD α = 0.05 there is a difference between treatments, and  boiling gives the best results with the average results of HCN concentration: 0%, and the observation of the second phase showed that the effect of length of fermentation by ragi  tape affect glucose concentration, which average at P0: 35.609 ppm; P1: 44.473 ppm; P2: 51.681 ppm; and P3: 91,, 484 ppm. The LSD α = 0.05 there is a difference between treatment and at P3: 72 hours showed the best effect with an average glucose level; 91.48 ppm The LSD α = 0.05 there is a difference between treatment and at P3: 72 hours showed the best effect with an average glucose level; 91.48 ppm. Can be concluded that the best way because it boiling to  decrease HCN concentration on umbi gadung and long fermentation by ragit tape: 72-hour glucose concentration can increase umbi gadung flour
