Abstract

Background: Stroke can cause brain damage that ends up as a serious long-term disability. Some previous research mentioned that albumin as a neuroprotector in ischemic stroke. Albumin can improve ischemic stroke prognosis by anti-edema effects, hemodilution effects, and antioxidants effects. Methods: This study is an analytical observational research with a cross sectional approach. The amount of sample in this study is 32 ischemic stroke patients at Dr. Moewardi Hospital, Surakarta were selected by simple random sampling. The sample were selected according to both inclusive and exclusive criteria that determined by the researcher. The dependent variable in this study is ischemic stroke prognosis, the independent variable is serum albumin level, and confounding variable are age, stroke severity degree, premorbid conditions, and post-stroke complications. Researcher gives the explanation and helps the patients to fill (1) Biodata form and informed consent, (2) Serum albumin level, ages, stroke severity degree, premorbid conditions, and post-stroke complications, and (3) Barthel Index. The collective data were analyzed using the Spearman Test and then processed with odds ratio calculation. Then, confounding variable was calculated with binary logistic regression analysis. Result: Using Spearman Test obtained value (p) = 0,04 and a correlation coefficient of serum albumin level and ischemic stroke prognosis was 0.313. Based on the calculation, the value of odds ratio is 4.000 with Confidence of Interval is 0,828 19,325 (RO = 4,000, CI = 0,828 19,325). The result of binary logistic regression analysis was known that influential variable in ischemic stroke prognosis is stroke severity degree (RO = 36,000) and post-stroke complication (RO = 3.441.206.744). With constant at 23,463, obtained the equation: . Conclusion: There is a statistically significant relationship between serum albumin level with ischemic stroke prognosis at Dr. Moewardi Hospital, Surakarta. Patient with low level serum albumin has 4 times greater suffered worse ischemic stroke prognosis than patients with normal serum albumin level. Keywords: Albumin, stroke ischemic prognosis

Abstract

Damage of using a synchronous machine in a power plant cannot be avoided especially when there is vibration produced by the machine. The loss incurred may lead to significant losses in the production process. Though maintaining an electrical machine in ideal condition is preferred, defect in machine fabrication cannot be avoided. Those defects may lead to friction between moving parts and produce vibration on the machine. Thus, to reduce losses and control the vibration of the system, vibration analysis of the device need to be done. For the reasons mentioned above, the author attempts to analyze the vibration as well as to minimize the losses incurred in the case of vibration exceeding the normal threshold. Predictive maintenance is expected to occur due to vibration disturbance in the generator. The research was carried out in PLTU Kaltim Teluk Balikpapan 2 x 110 MW. The analytical method used in this analysis is first, the monitoring method condition, which monitors the state of the engine through the data captured. Secondly, comparing the data obtained with the previous data to observe the changes occurring in the device. Lastly, analyzing the vibration categories based on ISO standard vibration (ISO 7919). From the operation data, alteration in the generator load will affect the temperature and vibration of the alternator. With a higher load, the vibration and temperature of the rotary generator will also have a higher value. By displaying the higher-direction vibration data of 131.7 μm with a load of 59.6 MW and a temperature of 64.6 ° C. From observation and data analysis, it is concluded that due to the uneven distribution of temperature in the rotor, synchronous generators undergo reversible thermal sensitivity symptoms.
