Analysis of Bell's Palsy Disease Classification Methods Using Machine Learning
Abstract
Bell's palsy is a condition that affects the facial nerves, causing sudden weakness or paralysis of the muscles on one side of the face. The classification of Bell's palsy disease is crucial for accurate diagnosis and prognosis. In recent years, machine learning algorithms have been explored as a potential tool to classify Bell’s palsy disease based on data types such as clinical information, imaging data, and electrodiagnostics. In this systematic review of the library, we analyzed the current state of research on the use of machine learning algorithms to classify Bell’s palsy disease using the Riview Systematic Literature (SLR) method by collecting important results from the literature studied. Our findings suggest that some studies have used different kinds of machine learning algorithms, such as support vector machines (SVM) and convolutional neural networks . (CNN). The algorithm shows a high degree of accuracy in classifying Bell's palsy disease and predicting its severity or outcome. But further research is needed to validate these findings and explore the potential use of other types of data for classification purposes. Using machine learning algorithms to classify Bell's palsy disease has the potential to improve the accuracy of anginosis and prognosis as well as the implementation of the condition in a comprehensive way by using a wide range of data and analyzing it accurately, so long as doctors can plan treatment that is tailored to the unique needs of patients by predicting the severity and outcome of treatment

Analysis of Mangrove Vegetation in Eyat Mayang Village, Lembar Sub District, Lombok Barat Regency
Abstract
Eyat Mayang Village has the potential for a mangrove ecosystem and is part of the Essential Ecosystem Area (KEE) of the Lembar Bay Mangrove Corridor. The purpose of this research is to analyze the structure and composition of mangrove vegetation in Eyat Mayang Village. Data collection was carried out through sample plots using the grid path method. The number of sample plots was determined using a sampling intensity (IS) of 5.5% with a total of 84 sample plots. Analysis of the composition of the mangrove vegetation included the importance value index, diversity index, species richness index, evenness index. The results showed that the composition of the mangrove vegetation in Eyat Mayang Village consisted of five major mangrove species belonging to three families. Rhizophora apiculata species had the highest IVI value and became the dominant species at all growth stages. The diversity index at the tree and pole growth stages is in the medium category, while the seedlings have low diversity and the species richness index at all stages is in the low category. The evenness index of trees is in the almost even category, while the poles and seedlings are in the fairly even category. The horizontal structure of the mangrove vegetation shows that the density at the seedling level is the highest and the density of trees is the lowest. The relationship between diameter classes and density shows the best "J" curve which indicates that the larger the diameter the lower the density and this is a natural condition in natural forest areas. The vertical structure shows that the mangrove vegetation in Eyat Mayang Village belongs to stratum C (4 – 20 m) and stratum D (1 – 4 m)
