This study aims to determine the effect of learning using problem-based learning strategies on student learning outcomes on environmental change material at Teladan Batu Bara Madrasah Aliyah. This research is a type of quantitative research with a quasi-experimental design selected by Nonequavalent pretest posttest control group design. The research population was class X IPA Madrasah Akiyah Exemplary and the sample of this study was Class X IPA 1 with a total of 35 students as the experimental class, and X IPA 2 with a total of 35 students as the control class. The instrument in this study was in the form of a test in the form of multiple choice questions of 30 items. Data analysis of student learning outcomes using the t-test formula, also with the help of SPSS version 25 data processing. Data analysis of student learning outcomes with the results of calculating the relative learning outcomes shows that the experimental class using problem-based learning strategies is higher than the control class. The prerequisite test proved that the data were normally distributed and homogeneous. The results of simple linear regression test calculations show sig < 0.005, 0.000 problems < 0.05, this means that there is an influence from the problem- based learning system on student learning outcomes. The conclusions in this study explain that there is an effect of using problem-based learning strategies on student learning outcomes.

Shrinkage is the reduction of medical records on storage shelves by moving inactive medical records to a different room from the active shelf seen from the last patient visit. The purpose of this study was to determine the implementation of shrinkage at the Kembangan Regional General Hospital. This research method uses a qualitative descriptive method by means of interviews and observations in the medical records unit. So it can be concluded from the results of the study that the Kembangan Regional General Hospital already has SOP related to shrinkage which is divided into SOP sorting, media transfer and destruction. In the implementation of shrinkage, officers carry out the process of sorting, transferring and transferring media every day. But officers do not conduct an assessment based on use value. The destruction process is carried out when the number of medical records has reached 2 tons by using a third party to make medical records in the form of pulp. The main obstacles to the implementation of shrinkage are officers who do not have a decree on duties and teams so that officers often delay the implementation of shrinkage, paper quality that makes it difficult for officers to see medical record sheets in the past year and scan machines that heat up quickly due to continuous use. Therefore, the Kembangan Regional General Hospital should complete the SOP related to shrinkage, make a decree of duties and conduct an assessment stage so that the implementation of shrinkage is carried out properly, and add a scan machine so that the implementation of media transfer is not delayed.

Background : Spinal anesthesia is an anesthetic technique used to inhibit pain in some parts of the body. One of the complications that can occur is Post Operative Nausea and Vomiting (PONV). PONV can be caused by many factors, one of which is hypotension. Hypotension can lead to hypoxemia and hypoperfusion in the Chemoreceptor Trigger Zone (CTZ) as the center of vomiting stimulation. Objective : The study aimed to determine the relationship between hypotension and the incidence of Post Operative Nausea and Vomiting (PONV) in spinal anesthesia patients. Research Methods : This type of research is analytic observational with cross sectional research design. The population in this study were all patients undergoing spinal anesthesia at RSI Sultan Agung Semarang. Sampling in this study was to use the purposive sampling method of 53 samples and to use the chi square data analysis test. The research instrument used interviews and used observation sheets. Reseach Result : The most age of respondents in this study were 26-35 years old as many as 18 respondents (34.0%), the most gender was female 32 respondents (60.4%), and those who experienced hypotension were 29 respondents (54.7%) , while there were 30 respondents who experienced PONV (56,6%) .The results of the Chi-Square test to determine the relationship between hypotension and the incidence of Post Operative Nausea and Vomiting (PONV) yielded a result of 0.000 (P <0.5). The majority of respondents who experienced hypotension were 24 people (45.3). Conclusion : here is a significant relationship between hypotension and the incidence of Post Operative Nausea and Vomiting (PONV).
