Air fresheners are products that contain chemicals aimed at reducing unpleasant odours in confined spaces. The use of synthetic air fresheners turns out to harm health because some of their leased Volatile Organic Compounds are classified as toxic compounds and are carcinogens. Air freshener enters the body through the inhalation process in the respiratory system. Modern air fresheners are available in liquid (aerosol) and gel forms. Air fresheners contain addictive substances and solvents such as 1,4-dichlorobenzene which can affect pulmonary function. The purpose of this study is to know the effect of exposure to liquid air freshener on the histology of bronchi of mice (Mus musculus). This study used 20 male mice (Mus musculus) consisting of 4 treatments with 5 replications. The research design is true experimental in the form of a post-test only control group with Completely Randomized Design (CRD). The post-test was done by observing the histological picture of the mice's bronchi after exposure to liquid air freshener given 3x/day for a period of P1 = 2 weeks, P2 = 4 weeks and P3 = 6 weeks. Quantitative data on bronchial histology was tested using the One Way ANOVA statistical test followed by the Post Hoc Tukey test. The results of the study found changes in the histology of the bronchi, thickening of the epithelial tissue of mice. Analysis of comparative data between the control and treatment groups statistically obtained p = 0.010 <0.05, meaning that there was a significant effect and change in the bronchial tubes exposed to liquid air freshener. Histologically there were differences in histology between the control and treatment groups. It was concluded that liquid air freshener had a significant effect on the histological picture of the mice's bronchi.

Abstract: Elastomeric ligature is used to fasten orthodontic wires with brackets and can be stretched 1-3 mm as a simulation of bracket in the oral cavity. Its elastic force could decrease caused by salivary pH and water absorption of the elastomeric ligature. Consuming carbonated drinks causes the oral cavity to become acidic which increases the loss of elastic force in the elastomeric ligature with length of stretch variations. This study was aimed to determine the effect of immersion in carbonated drinks on the elastic force of the elastomeric ligature with length of stretch variations. This was an experimental laboratory study with a post-test only control group design. There were a total of 24 samples of American Orthodontic brand elastomeric ligature with royal blue color divided into six groups, consisting of three control groups immersed in artificial saliva, and three treatment groups immersed in carbonated drinks. Each control group and treatment group were given three variations of stretch length, as follows: 1, 2, and 3 mm. The calculation of the elastic force on the elastomeric ligature was performed by using the Universal Testing Machine. Data were analyzed by using the One Way Anova test and LSD post hoc test (p <0.05). The One Way Anova test showed a significant difference in the 1, 2, and 3 mm length of stretch variations for treatment groups. In conclusion, carbonated drinks affect the elastic force of elastomeric ligature with length of stretch variations.Keywords: elastomeric ligature; carbonated drinks; length of stretch variations Abstrak: Elastomerik ligatur adalah alat yang digunakan untuk mengikatkan kawat ortodonti dengan braket, dapat diregangkan 1-3 mm sebagai simulasi braket dalam rongga mulut.

ABSTRACTBackground: Panoramic radiography is one of the most commonly used radiographic diagnostic tools. Panoramic radiography exposure can increase the GCF flow because of increasing vascular permeability.GCF flow can also increase in periodontitis conditions. Objective: The purpose of this study was to analyze the effects of 1, 2, and 3 times exposure of panoramic radiography to the volume of GCF in wistar rats with periodontitis. Method: This research was true experimental with post test onlycontrol group design. Thesampling technique used simple random samplingthat obtained 25 wistar rats comprising of 5 wistars from each group in which the GCF samples of each group was collected from. Results: The average number of GCF inhealthy rats groupthat was not exposed to panoramic radiographywas 0.114 µL, the periodontitis rats group that was not exposed to panoramic radiography was 0.246 µL, the periodontitis rats group that was exposed1 time was 0.286 µL, the group of periodontitis rats exposed 2 times was 0.294 µL, and periodontitis group of rats exposed 3 times was 0.374 µL. The results of the One-Way Anova and Post Hoc Bonferroni tests stated that there is a significant increase in the volume of GCF between the control group and all other treatment groups, as well as between the non-exposed periodontitis group and the periodontitis group with 3 times exposure. Conclusion: Panoramic radiography can causeincrease the volume of GCF in wistar rats with periodontitis. Keywords: Gingival Crevicular Fluid,panoramic, periodontitis, wistar rats

The purpose of this study was to examine the effects of analogy and explicit instructions on 50-m sprint performance and their running kinematics. Forty-five male Physical Education undergraduates participated in this study and were randomly divided into three groups, (i.e. analogy, explicit and control). Their sprint performances were assessed using wireless timing gate while the kinematic data was assessed by Kinovea software. The analogy group received three analogies which were “run tall”, “chin to pocket” and “claw the track” throughout the intervention sessions whereas the explicit group received “keep the body posture in an upright position and aligned, head and butt not tilting outward”, “arms should maintain a 90-degree angle at the elbow throughout the upswing as well as backswing” and “the foot landing should always be on the balls of the feet”. The control group did not receive any instruction throughout the intervention period. All participants were tested again after three weeks for the post test and retention test a week after. A 3 group x 3 tests mixed design ANOVA was used to analyze the sprinting performance whereas the kinematic data was analyzed by using one way MANOVA test. Results displayed that there was no significant difference in sprint performance among the groups. However, the post hoc test showed that the analogy group improved significantly in the post test. The kinematic data showed that both intervention groups were significantly better than the control group. This study concluded that both analogy and explicit instructions resulted in better running mechanics but only the analogy group elicited better in performance. Thus, analogy instructions are suggested to be an effective method to coach sprinters.

The study compared two death education programs for mothers ( N = 90) of young children. Pre- and post-test scores on the State-Anxiety Scale and researcher-designed instruments that included the Children's Questions About Death Scale (CQADS) and Future Plans Inventory (FPI) were compared. Mothers in both the Didactic and Didactic-Experiential programs scored significantly higher than the Control group in their level of effectiveness in responding to children's questions, but the two treatment groups did not significantly differ from each other. Neither the Didactic Death Education nor the Didactic-Experiential Death Education programs significantly affected mothers' anxiety before responding to children's questions about death. Post hoc analyses suggested trends relating subject characteristics to mother's level of effectiveness in responding to a child's questions about death.

ABSTRACTMosquitoes are type of insect that acts as a disease vector. One of them is Culex sp mosquitos which their existence is many around us. In Indonesia there are still a lot of disease cases that caused by Culex sp mosquitos, one of them is filariasis disease. The efforts to control thecurrent population of Culex sp mosquitoes mostly use chemical insecticides. The control becomes difficult because of the resistance to chemical insecticides and adversely affects the environment. This study aims to determine the potential of jackfruit leaf extract as biolarvasida against Culex sp. The type of this study was post test onlycontrolled group design, using 625 larvae Culex sp instar III, divided into 5 groups (negative control group, 0.25% extract, 0.50% extract, 0.75% extract, extract and 1% extract). Observation was performed 24 hoursafter the treatment and counted the number of larvae death.The data were analyzed by Kruskal Wallis test followed by Post Hoc Mann-Whitney U test to determine the killing power of leafy leaf extractusing Probit analysis. The results of data analysis in this study were thedeath rate percentage of larvae after 24 hours treatment was 0% incontrol, 44% in 0.25%extract, 52% in0.50% extract, 60% in 0.75%extract,while in the extract group of 1%, the number of larval deaths was 72%. Itobtained results with significant differencein some treatment groups thatwere concentrations of 0.25% - 1%. Probit analysis showed that LC50 wasat 0.382% concentration.From results of the studyit can be concluded that jackfruit leaf extract(Artocarpus heterophyllus Lamk) was potential as Culex sp mosquitobiolarvacide. So it is necessary to conduct further research on the effectsof compounds that contained in other plant parts such as flowers, stemsand roots which will be expected to have a function asbiolarvasida.Keywords: Leaf Jackfruit, Biolarvasida, Mosquito Culex sp
