Abstract

ABSTRACTBacteriological disease that caused by bacteria V. Harveyi often lead to any damage in shrimp cultivation. The study of the role of calyx and fruit extract of mangrove S. Caseolaaaris (L) for preventation and healing on infection by bacteria V. Harveyi to shrimp (P.monodon Fab) have conducted. Dosage level that applied in  this study, both preventation and healing is 100 ppm and 200 ppm, respectively, obtained in the result of the preventation and healing experiment. For hemocyt, percent of granulosit increased and decrease for percent of hialin, contrastly if compared with  control. Application of mangrove extract can  also increase the resistence of shrimp after infectedby bacteria V. harveyi and decreasing of bacteria level in the body of shrimp. By histological observation, appearing normality of digestion system with the rich of food in digestion tract after application of mangrove S. caseolaris (L) can  applicated for preventation and healing to infection of bacteria V. harveyi to shrimp.Key words :  Bacterial infection, Vibrio harveyi, Sonneratia caseolaris, tiger shrimp. ABSTRAKPenyakit bakterial yang disebabkan oleh bakteri Vibrio sering menimbulkan masalah pada budidaya udang. Penelitian untuk mengetahui peranan ekstrak kelopak dan buah mangrove Sonneratia caseolaris (L), untuk pencegahan dan pengobatan terhadap infeksi bakteri Vibrio harveyi pada udang windu (Penaeus monodon Fab.) telah dilakukan.  Dosis yang digunakan pada percobaan ini adalah 100 ppm untuk  pencegahan dan 200 ppm untuk pengobatan.  Didapatkan hasil pada percobaan pencegahan dan pengobatan untuk jenis hemosit terjadi kenaikan persentase granulosit dan penurunan persentase hialin dan bila dibandingkan  dengan kontrol hal ini terjadi sebaliknya.  Pemberian ekstrak mangrove juga meningkatkan ketahanan hidup udang windu setelah diinfeksi dengan bakteri V. harveyi dan penurunan jumlah bakteri yang terdapat pada tubuh udang.  Gambaran pengamatan histologis memperlihatkan terjadinya kenormalan pada organ pencernaan dengan penuhnya saluran pencernaan oleh pakan setelah pemberian ekstrak mangrove.  Dari hasil penelitian dapat disimpulkan bahwa ekstrak kelopak dan buah mangrove (S. caseolaris) dapat dipergunakan untuk pencegahan dan pengobatan terhadap infeksi bakteri V. harveyi  pada udang windu.Kata kunci :  Infeksi bakteri, Vibrio harveyi, Sonneratia caseolaris, udang windu.

Abstract

Introduction: The World Health Organization (WHO) estimates that one million people worldwide suffer from disabilities and even deaths annually as a result of unsafe healthcare practices. This fact requires improving the quality of health services. The quality of these services can be reflected by patient satisfaction. Patient satisfaction is also supported by a doctor-patient relationship and it is the foundation of the medical practice and medical ethics. This study aimed to determine the association between sensitivity of medical ethics and patient's satisfaction. Methods: This research was an observational analytical method with cross sectional approach. Subjects in this study were inpatients and postgraduate medical students at Dr. Moewardi Hospital. The samples of research were taken using the simple random sampling and convenience sampling technique. The data of research were analyzed using Pearson?s correlation test. Results: From the results of data analysis, correlation between sensitivity of medical ethics and patient's satisfaction with p = 0.078, which means not statistically significant, but with the moderate correlation power and direction of the correlation was a positive correlation (r = 0.469). Conclusion: There is positive correlation between ethics physicians with patient satisfaction Keyword: Medical Ethics, Patient?s Satisfaction, Doctor-Patient Relationship

Abstract

Introduction: Academic motivation is the most important factor in affecting academic achievement in medical education. Career in medicine that divided into clinical and non-clinical career is the output of medical education. Knowledge of medical career preferences can be obtained from information during education process. This study aims to investigate the correlation between knowledge of medical career preference and academic motivation in medical student of Sebelas Maret University. Methods: This study was an observational analytic with cross sectional approach. Subjects were 147 preclinical medical students in Sebelas Maret University using stratified random sampling. Knowledge of medical career preferences data was collected using valid and reliable questionnaire. Academic motivation data was collected using Academic Motivation Scale. Data were analyzed with Spearman correlation test. Results: The lowest average score of knowledge of medical career preferences was the first year student and the highest was the final year student. The lowest average score of academic motivation was the second year student. The Spearman correlation test showed a positive correlation (r=0,077) and statistically insignificant (p=0,355) between knowledge of medical career preference and academic motivation. Conclusion: There is a very low positive correlation and statistically insignificant between knowledge of medical career preference and academic motivation in medical student of Sebelas Maret University. Keywords: Academic motivation, knowledge of medical career preference, medical career.

Abstract

Background: Surgical site infection is clinically defined as a discharge of purulent around wounds or cellulitis inside postoperative wounds. One of the factors that cause surgical site infections is the ESBL producing bacteria that developed a resistance towards most antibiotics. Aloe vera L. is known to possess a lot of antibacterials potent against various bacteria, either gram-positive or gram-negative. This research aims to prove the effects of the administration of Aloe vera L. leaf extracts towards  the growth of ESBL producing bacteria from surgical site infection isolates. Method of research: This research was an experimental laboratory  research (post test only with control group design) with sampling technique non-probability sampling ;  consecutive sampling. The research was done in the UNS Faculty of Medicines Laboratory of Microbiology. Extraction of samples was done in the Dr. Moewardi Public Hospital Laboratory of Microbiology.The independent variable of this research was 70% ethanol extracts of Aloe vera L. leaf with concentrations of  25%, 50%, 75%, and 100%. The research subject was surgical site infection isolate ESBL producing bacteria, standardized with Mc Farland 0.5. Sensitivity test on the Muller-Hinton medium used the diffusion method with cefoperazon/sulbactam as positive control and aquades as negative control. The result of research was tested with Kruskal-Wallis­ testing method followed by Mann-Whitney testing method. Results: Kruskal-Wallis test results indicates a significant interception potential between two treatment groups (P = 0.000). Mann-Whitney test results indicates a significant difference of interception potentials on every treatment group, with the exception of the interception potential groups of 75% concentration extract and 100% concentration extract, no significant interception potential was found (P = 0.179). Conclusion: Aloe vera L. leaf extract proves to possess potential activity interception towards the growth of ESBL producing bacteria from surgical site infection isolates. The concentrations of Aloe vera L. leaf extract possess a positive correlation towards the interception potentials on surgical site infection ESBL producing bacteria. Keywords: Infection, postoperative wound, ESBL, Aloe vera.
