Studi Pengaruh Ukuran Pixel Imaging Plate Terhadap Kualitas Citra Radiograf

This study aims to determine the image on each imaging plate which has a different pixel sizes. This research is using a plane X-ray, Computed Radiography (CR) which is used in the diagnostic field. This study uses three imaging plate each having size of 0.097 mm, 0.115 mm and 0.168 mm with stepwedge objects on it and use the same factor, namely kV eksposi: 64.5 and mAs: 16. In each of the imaging plate in eksposi 3 times and the results of each radiograph imaging plate will be measured by using a densitometer. Stepwedge radiograph of the measurement results will be obtained the density and contrast value of each imaging plate. Contrast value for each imaging plate will be compared so they will know what the size of the imaging plate which has a higher contrast value. Research on the effects of different pixel size on the imaging plate is done in Radiology Hospital Tugu Semarang, in July 2014. From the results it can be concluded each different pixel sizes on the imaging plate will generate a different image quality

Karakterisasi Plasma Jet Argon Menggunakan Kolom Dielectric Barrier Discharge (Dbd) pada Tekanan Atmosfer

An atmospheric of Argon plasma jet is generated with column dielectric barrier discharge high voltage alternating current. Characterization of Argon plasma jet is used to observe the effect of variations in the voltage (V) to the length of the plasma jet. Voltage (V) and current (I) were analyzed to identify its effect to the length of the plasma jet. In this study, Argon gas is passed through the capillary column by regulating the flow rate of gas. Then the voltageis being increased until the plasma jet can be seen. Voltage is used consecutively in the range 0 to 10,5 kV at flow rate of Argon gas is 3 L / min. The result shows that electrical current increase and then reach saturation condition by the increase of voltage. The increase of the length of the plasma jet were given by the increase of the applied voltage. This research indicates that the length of the plasma jet characteristics tends to increase. The value of the voltage is affects to the value length of the plasma jet

While the current as a function of geometry shows the value of the current flowing inversely proportional to the geometry factor of the electrode distance change

Effectiveness of progressive muscle relaxation in reducing depression, anxiety and stress among haemodialysis patients attending a Public Hospital at Central Java Indonesia

The increasing trend of Chronic Kidney Disease (CKD) prevalence in Indonesia is a public health concern as it increases mortality, morbidity and burden of disease that has great implication on the health economic. In addition, CKD patients who are more likely to undergo hemodialysis is commonly associated with psychological problems such as depression, anxiety and stress and these have added more to the disease burden. Immediate measures such as progressive muscle relaxation (PMR) to reduce the psychological symptoms is of great importance before the symptoms progress into psychiatric disorders. The study was aimed to evaluate the effectiveness of PMR in reducing symptoms of depression, anxiety and stress among patients undergoing hemodialysis. It was a quasi-experimental, pretest-posttest control study that recruited 60 eligible respondents who underwent hemodialysis and was randomly allocated into intervention and waitlist control groups. Respondents in the intervention group performed PMR twice a day for two weeks. Mean scores of depression, anxiety and stress of respondents were examined before and after intervention using Depression, Anxiety and Stress Scale–21 questionnaire (DASS-21). Results showed that mean scores of depression, anxiety and stress differed significantly before and after intervention between groups and within the intervention group (p<0.005). PMR was effective to reduce the psychological symptoms among patients underwent hemodialysis. This highlight the importance to screen psychological symptoms among those patients and PMR should be taught to them as one of the stress-reducing measures
