This study aimed to determined the effectiveness of kaffir lime leaf extract (Citrus hystrix) as a natural insecticide against cockroach americana (Periplaneta americana) with spray method. This research was an experimental study with a post-test only control group designed design. The sample in this study was 60 cockroaches, the sample was divided into 6 groups: negative control (aquades), positive control (transflutrin 0.06%) and and 4 test groups with concentrations of kaffir lime leaf extract (20%, 40%, 60% , and 80%) each group consisted of 10 cockroaches. Phytochemical tests were carried out to determine the content of secondary metabolites in extracts of kaffir lime leaves. Positive phytochemical test results containing flavonoids, alkaloids and essential oils. Based on probit analysis, it is known that the LC50 value = 58.5%; LC95 = 85.1%. The time of death of LT50 is fastest at a concentration of 60% (3,036 hours) and LT95 is the fastest at a concentration of 80% (5,960 hours). Anova test analysis results showed that the positive control group had no significant difference with kaffir lime leaf extract concentration of 80% Kaffir lime leaf extract has an insecticide effect, the higher the concentration of kaffir lime leaf extract, the more number of dead cockroaches and the longer the observation time, the number of cockroaches death will also increase.

Introduction: Dengue hemorrhagic fever is one of the most common infectious diseases in Indonesia. The vector of this disease is Aedes aegypti (Ae. aegypti). Dengue hemorrhagic fever can be controlled by a few measures, one of them is using insecticide. However, frequent use of chemical insecticide could lead to resistance and is harmful to non-target organisms. One of the solutions for this problem is the use of bioinsecticide derived from lemongrass (Cymbopogon citratus or C. citratus) leaves extract. Methods: The design of this study is true experimental post-test only control group. The population used are adult Ae. aegypti mosquitoes. For each experiment, 10 mosquitoes are required and given the extract of C. citratus in 2%, 10%, and 20% concentrations, and negative control respectively.The lethal effect of the extract is observed in 10, 30, 60 minutes and 6, 12, 18, 24 hours. Results: There is a significant difference in the lethal effect of Ae. aegypti mosquitoes with variations in duration of exposure to the C. citratus leaves extract (p = 0.007), but no significant difference with variations in extract concentration given (p = 0.281). Conclusion: C. citratus leaves extract has bioinsecticidal effect on Ae. aegypti mosquitoes. The optimal result of mosquito mortality is achieved by using the extract in 20% concentration with duration of 12 hours.

Abstract: Introduction: Soil-transmitted helminth is a group of nematoda worm parasite that causes infection in human because the egg is swallowed or direct contact with the larva. More than two billion people in the world had infection for at least one spesies of the nematoda worm, especially A. lumbricoides, T. trichiura and A. duodenale. Ascaridia galli is a worm parasite that classifeid in nematoda fillum. Ascaridia worm has the same genus with Ascaris Lumbricoides that infect human. Antihelmintic is a drug that can eradicate the worm in human and animal body. There is a side effect in the antihelmintic drug like Mebendazole so another alternative like organical antihelmintic from papaya leaves (Carica papaya L.) is needed. This research is a true experiment with post test control group design. The subjects were 160 Ascaridia galli worm which were divided into 5 worms in each test group (5%, 10%, 20%, 40%, 60%, dan 80%), positive control group (Pirantel pamoat 0,5%) and negative control  repeated as many as 4 replications. The treatment was given for 12 hours and observed the number of dead worm at each hour. Data were analyzed by statistical test of Kruskal Wallis Test and followed by post-hoc Mann-Whitney Test. It is also tested the probit analysis to determine lethal time (LT50 and LT90) and lethal concentration (LC50 and LC90).There was a significant difference (p <0.05) between all test concentrations except between 5% to negative control. It could be evidenced that the papaya leaves (Carica papaya L.) has an antihelmintic effect on Ascaridia gall. The results of probit analysis for LC50 and LC90 were 6,182% and 14,422% respectively. It is known that LT50 at concentrations of 25%, 10%, 20%, 40%, 60%, and 80% respectively were 11,84 hours, 10,536 hours, 9,328 hours, 6,794 hours, 5,472 hours and 2,892 hours. While the LT90 at concentrations of 25%, 10%, 20%, 40%, 60%, and 80% respectively were 13,608 hours, 12,303 hours, 11,095 hours, 8,562 hours, 7,24 hours, dan 4,66 hours.The ethanol extract of Papaya leaves Carica papaya was shown to have an antihelmentic effect on Ascaridia galli effectifically at concentrations of 10%, 20%, 40%, 60% dan 80%. The values of LC50 and LT50 at highest concentration (80%) at the end of the observations are 6,182% and 2,892 hours respectively. The values of LC50 and LT90 at the highest concentration (80%) were 14,442% dan 4,66 hours respectively. The higher concentration of ethanol extract of papaya leaves Carica papaya the greater the effectiveness in killing Ascaridia galli. Keywords: Antihelmintic – Ascaridia galli – Carica papaya L. – Lethal Concentration – Lethal Time

Aim: To evaluate the incidence of apical root crack formation after root canal preparation using ProTaper Universal (PTU), ProTaper Next (PTN) and ProTaper Gold (PTG) rotary file systems and compare the crack formation at various instrumentation lengths. Subjects and Methods: One hundred single rooted extracted mandibular premolar teeth were mounted in acrylic resin blocks after simulating periodontal ligament. The teeth were divided into four groups. Group I was instrumented using PTU, group II using PTN and group III using PTG rotary files, while group IV was left untreated, serving as a negative control group. Each group was subdivided into three subgroups: A, B and C instrumented till root canal length (RCL), RCL-1 and RCL+1. Root apex was sectioned horizontally 1-2mm from apical foramen and was stained with 1% methylene blue dye followed by stereomicroscopic evaluation to determine apical root cracks. The data was analyzed using chi-square, Shapiro Wilkinson and Cramers phi test. The significance level was set at P<0.05. Result: Significant difference was seen in percentage of cracks after instrumentation with PTU and PTG, while no significant difference with PTU and PTN. Specimen instrumented upto RCL-1 showed less cracks as compared to those instrumented upto RCL and RCL+1. Conclusion: PTG produced least number of cracks followed by PTN and PTU. Moreover, instrumentation at RCL-1 reduced the crack formation.
