<![CDATA[Asiatic citrus psyllid Diaphorina citri Kuwayama has been considered as one of important citrus pests and a vector of a serious citrus disease as well, greening disease or known as Huanglongbing (HLB). Among entomophatogenic fungi which can be used to control those pest insects isBeauveria bassiana.The objective of this study was to measure the infectivity ofB. bassianaagainst adult of D. citri.B. bassianaconidia that used were 103, 104, 105, 106, 107, and 108conidia/ml.The experiment was repeated three times and arranged in a completely randomized design (CRD). Mean was analized by Duncan's multiple range test correction at the level α=0.05. B. bassianacaused mortality of D. citriat rate of 10%, 15%, 18.33%, 26.67%, 33.33% and 53.33% respectively. The result showed that LC50 of B. bassianawas 1.52 x 108conidia/ml.]]>

<![CDATA[This research aims to study Tartrazine and Zinc (Zn) status in blood sample of Attention Deficit Hyperactivity Disorder (ADHD) children. Deductive research using the descriptive method through 3 stage, namely : 1. Taken of blood sample, 2. Analysis of Tartrazine status in blood sample was performed by using High Performance Liquid Chromatograpy (HPLC) method, and 3. Analysis of Zinc (Zn) status in blood sample were measurements by using Atomic Adsorbance Spectrophotometry (AAS) method. Data were analyzed using descriptive analysis techniques and Chi Square tests (X2) by Computer programs (SPSS 15). The result of the assessment of Tartrazine status in blood sample of ADHD children that had been was considered statistically highly significant a increase of the assessment of Tartrazine status in blood sample of ADHD children by 130 mg/ml compared with laboratory reference (control) by 28 mg/ml, HA>C** (p<0,001). The result of the assessment of Zinc (Zn) status in blood sample of ADHD children that had been was showed statistically highly significant a reduce of the assessment of Zinc (Zn) status in blood sample of ADHD children by 0,37 µg/ml compared with laboratory reference (control) by 0,64-1,18 µg/ml, HA<C** (p<0,001). This was considered a reduction and increase in Tartrazine and Zinc (Zn) concentrations induces of the Hyperactivity children by 95%.]]>

<![CDATA[Rusa timorensisis native wildlife Indonesia which have protected status that require attention in order to preserve and utilization. This study aimed to preference level of the type of diet, and mineral nutrient content of feed in the conservation area Peucang Island. Data collection was performed by following the daily movement of deer and record all types of plants are edible. Neu indexes was used to scoring of level feed,chi square test was used to distinguish in the level of preference, and inspection of feed nutrients and minerals was done in the laboratory animal science. The results showed Cynodon dactylon, Axonopus compressus, Hibiscus tiliaceus, Dendrolobium umbellatum, Lagerstroemiawhere the types of feed most preferred by the index value of the preference of feed w> 1, there where differences in the choice of feed indicated by the chi-square test χ2count = 23.1850> χ2 (0:05, 10) = 18:31, nutritional value and mineral feed in the forests and grasslands showed no significant difference (p> 0.05). Deer in Peucang have a tendency to choose the type of feed that contains the same nutrients and minerals between feed in the forest or grassland although of a different kind.]]>

<![CDATA[The use of antimicrobial such as antibiotics against infectious diseases with no control is quite common in Indonesia. This leads to increase morbidity and incidence of drug resistance. Staphylococcus aureus is a pathogenic bacteria, particularly infects the skin. The resistance it difficult to determine which antimicrobials were suitable for therapy. Manukan leaves have an active substance Rhinacanthin can be used as an anti-bacterial. The aim of this study was to determine the inhibition of ethanol extract of manukan leaves (Rhinacanthus nasutus (L) Kurz) against gram-positive bacteria (Staphylococcus aureus) in vitro with the extract concentration of 15, 30, and 60% as a control. This study was a true experiment through the in vitro test with the Kirby Bauer method. The results showed that the average diameter of the inhibition zone was at an extract concentration of 15, 30, and 60% are 9.97 mm, 10.95mm, and 13.18 mm. The Kruskal-Wallis test results showed a significant difference between the four treatment groups (p= 0.010). The Mann-Whitney test showed significant differences in the inhibition zone between control and treatment at 15, 30 and 60% (p= 0.037). In conclusion leave ethanol extract of manukan has antimicrobial activitiy in inhibiting staphylococcus aureus.]]>

<![CDATA[Activator that has been successfully used in the process of activation of activated carbon from coconut shell is Na2CO3, NaCl, HCl, H2SO4 and NaOH. The addition of activator in the activated charcoal will enlarge the surface area of the charcoal with open pores are closed, so as to increase the adsorption capacity of activated carbon. In the process of making activated carbon from coconut shell charcoal, carbon obtained randemen quite high, ranging from 80 to 81.74 wt% of carbon initially obtained with water content ranging from 2.2864 to 3.9489% and ash content of 2.04 to 3.28%. This means that the active carbon can be used as an activated carbon is good, because it meets the standards SII quality activated carbon. From the results obtained can be seen that the solution of HCl, NaOH and Na2CO3 can be used as an activator of activated carbon in the lower levels of peroxide. The addition of these activators can enlarge the surface area of the carbon that is by breaking the bonds of hydrocarbons or oxidizing surface molecules. Based on the research results, the best solution is used as an activator of activated carbon in adsorbing peroxide is an alkaline solution that is equal to 91.11% of the initial peroxide content.]]>

<![CDATA[Clean and Healthy Lifestyle is essential to be endeavored by society for preventing variety of infectious diseases which one of the most common is dandruff or seborrhea sicca that caused by the growth of Pityrosporum ovale fungi. This research is indicated to provide a better alternative option using ingredient given by nature that can treat dandruff. This research using banana peel extract since it is an original fruit from North Sumatra. The result from phytochemical screening of the banana peel extract shows secondary metabolites which are saponin, tannin, steroid/tritepenoida, flavonoid and glycosides. To produce barangan banana peel extract is by maseration method. Antifungal activity test using barangan banana peel extract towards Pityrosporum ovale is done by disc diffusion method. The antifungal activity test shows the biggest result for Minimum Inhibitory Concentration (MIC) extraction concentration at 1000 mg/ml with the average diameter of 11,9 mm. According to the inhibitory scale of antifungal activity test of barangan banana peel extract towards the growth of Pityrosporum ovale is ineffective.]]>
