Abstract

The purpose of the research is to analyse the history and dynamics of formal Islamic education institutions in Kaur Regency, Bengkulu Province. The type of research used is field research, with a descriptive qualitative approach. This method is to describe what it is about the History and Dynamics of the Development of Islamic Education Institutions in Kaur Regency, must be described as it is, with the aim of understanding the meaning contained in the history. In its implementation, the historical research method requires auxiliary sciences such as Sociology of educational sciences, Islamic Cultural History, and others. The results of the research show that, the history and dynamics of the development of Islamic institutions have now begun to appear with the support of the government and the changing understanding of the community about the importance of Islamic education. And so far, which is a factor in the difficulty of developing Islamic educational institutions, because it is affected by social changes in society, including community understanding, community economic factors, so that people to establish Islamic educational institutions are very constrained by funding, this is in line with the theory of dynamics.  Social dynamics occur as a result of interactions between people and between groups, so that between them there is a process of mutual influence that causes dynamics. Social dynamics occur in society in the form of changes in social values, norms prevailing in society, patterns of individual behaviour and organisations, the structure of social institutions, layers and classes in society, power and authority. In other words, social change includes changes in social organisation, status, institutions and the social structure of society. In addition, the slow development of Islamic education in Formal Schools is also a factor due to the lack of teachers who are civil servants, so automatically if most teachers are honorarium teachers, there is often a change of teachers, which is inseparable from the long historical dynamics influenced by the Dutch and Japanese colonisation.

Abstract

Bronchoscopy is a type of endoscope used to examine internal organs in the body. This examination is performed by competent physicians, by examining the bronchi or the branches for diagnostic or therapeutic purposes. The use of the LMA for airway management during Fiberoptic Flexible Bronchoscopy (FFB) was first introduced in 1989 and was described as a safe and favorable tool for airway control during bronchoscopy in both adult and pediatric populations. The advantage of an LMA over an endotracheal tube is that it is equipped with a larger diameter tube, allowing for better visibility and flexibility. The I-gel LMA is the most frequently used type of LMA. This study aimed to determine the satisfaction of pulmonologists with the use of LMA I-gel when performing bronchoscopy in Dr. Wahidin Sudirohusodo Central General Hospital Makassar. The research employed probability sampling with an experimental design, using questionnaires for data collection. There were 36 patients underwent bronchoscopy from June ? December 2023. Demographic data were collected (age, sex, body mass index, and American Society of Anesthesiologists physical status), assessment based on the first successful attempt of fiberoptic insertion with a value of p = 0,06, quality of visualization, flexibility of the scope, size of the fiberoptic that can be used, and limitations of performance during bronchoscopy with a value of p < 0,05. It was found that pulmonologists were satisfied with the use of I-gel LMA during bronchoscopy. However, this result was also influenced by the experience of pulmonologists in performing the procedure. Keywords: Bronchoscopy, LMA I-gel, Satisfaction

Abstract

This is a research of correlation study that aims to find the level of relationship between the ability to debate (in English) of the students of English Language and Culture Department at Darma Persada University and their perception of debating. The relationship is measured based on 3 variables, namely: 1) the students’ knowledge about debating, 2) the students’ self confidence in debating, and 3) the teaching process the students have to improve the debating skill. This study involves 75 students from 3 different classes. The students first went through a learning process about the concept of debating. Then they practiced debating. The students’ perception was measured through a research instrument in the form of a questionnaire, while the relationship values were taken from the scores obtained after students carried out tests in the form of debating. The result of this research indicates that the score for the correlation coefficient between the students’ ability in debating and the students’ knowledge on the definition on debating and technical ability on debating is 0.195. This means positive correlation between the variables. Secondly, in term of students’ self-confidence, the data analysis results a positive correlation coefficient between the students’ ability in debating and the students’ self-confidence. The score is 0.195 meaning a positive correlation. Lastly, in term of the teaching process in the course related to debate, the correlation coefficient is considerably high; 0.222. This means that the students have very positive attitude on the course.
