Abstract: Areca nut skin contains phenolic compounds which have antioxidant and sunscreen activities. This study aims to determine the levels of polyphenols, antioxidant activity and sunscreen contained in the extract and fraction of areca nut (Areca catechu L.) skin. Testing levels of polyphenols using Folin-Ciocalteau reagents, testing of antioxidants using the DPPH method with a comparison of vitamin C, and on sunscreen testing using the UV-Vis spectrophotometry method by calculating the SPF value. The results of this study indicate that the fraction of n-Butanol has higher polyphenol levels compared to extracts and other fractions with polyphenol levels of 13.88974%. In antioxidant testing it was found that the n-hexane fraction had very strong antioxidant activity with an IC50 value of 40.848 mg / ml. In the sunscreen activity test, it was found that the highest SPF value was at a concentration of 300 ppm, in the thick ethanol extract, n-hexane fraction, ethyl acetate fraction, n-Butanol fraction, and residual water fraction. The highest sunscreen activity of SPF value is the ethyl acetate fraction that is 24.79. From the results of the study it can be concluded that the skin of betel nuts has antioxidant activity, sunscreen, and polyphenol levels.

- RELATIONSHIP BETWEEN BLUE OCEAN STRATEGY, CUSTOMER BEHAVIOR, AND ISLAMIC
BANK PEFORMANCE
Authors: nasfi nasfi
Pages: 60 - 71
Abstract: There have been many studies conducted to determine the effect of differentiation strategies in business. Even so, there is still little empirical research that focuses on the impact of the blue ocean strategy on customer behavior in the financial services industry, especially banking. This study evaluates the effect of the blue ocean strategy on customer behavior and how it impacts on bank performance. Two hundred eighty-two customers from 20 Islamic commercial banks and Islamic business units filled out an online questionnaire. Overall, we found that the blue ocean strategy had a positive effect on advocacy behavior and customer loyalty. In addition, we find that advocacy does not have a significant effect on perceptions of bank performance, while loyalty has a significant positive effect on perceptions of bank performance. This result has implications for the importance of further research on the effects of the blue ocean strategy and the importance of sharia banking adopting this strategy consciously and systematically to increase customer loyalty and bank performance.

- ANALYSIS OF ACCURACY IMPROVEMENT IN RANDOM FOREST USING PRINCIPAL
COMPONENT ANALYSIS (PCA)
Authors: Hanna Willa Dhany, Muhammad Iqbal
Pages: 113 - 122
Abstract: Decision tree is used to classify a data that still does not know its class to existing classes. The data testing path is the first step that the root node goes through and finally the leaf node will predict the class for the data that has been concluded. Random Forest cannot be relied on for data types that have different categorical variables and therefore needs to be improved in the classification process, this is influenced by differences in the value of the variable. Therefore a method is needed to reduce features that are less relevant to the process of determining accuracy in the classification of the Random Forest method. In research conducted on the PCA + Random Forest classification model, using the Water Quality Status Dataset that has been simplified into 5 attributes, 4 classes and 117 instances with an accuracy rate of 91.43% with a classification error rate of 8.57%. Based on the test results from the four classification models, it can be concluded that the success of the PCA can be used as a reference to improve the accuracy performance of the Random Forest classification model

Students
Authors: Purwa Hasan Putra, Muhammad Syahputra Novelan
Pages: 152 - 159
Abstract: The X-Means algorithm is an algorithm used for grouping data. The x means algorithm is the development of k-means. X-means clustering is used to solve one of the main weaknesses of K-means clustering, namely the need for prior knowledge about the number of clusters (K). In this method, the true value of K is estimated in an unsupervised way and only based on the data set itself. The research results using the X-Means algorithm with Davies-Bouldin Index evaluation Determination of the number of Centroid clusters is done by modifying the X-Means method. In grouping this data, clustering is performed on each student data of the collected variables. Each student's gift and interest will be matched with the college and department of what each student is interested in
