This disease is caused by many factors, one of which is genetics, while the causes are age, gender, and family history. In this study, classification of 62 individuals with normal response and cardiovascular disease was carried out. Discriminant Analysis (AD) is a method that classifies data into two or more groups based on several variables where data that has been entered into one group will not be included in another group. The Support Vector Machine (SVM) performs classification by building an N-dimensional hyperplane that optimally separates data into two categories in the input space. Furthermore, AD and SVM will be compared to get which method has the best accuracy, after that it will be added to clustering using k-means and k-means kernels to improve the accuracy of each method. The results of this study are AD and SVM have accuracy values of 83.33% and 91.66%, for AD and SVM which are subjected to k-means have accuracy values of 91.66 % and 91.66 %, and for AD and SVM subjected to k-means kernel has an accuracy value of 100 % and 100 %.","PeriodicalId":353803,"journal":{"name":"BERKALA SAINSTEK","volume":"245 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134399741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Along with the increasing scale of development in the world of construction, more and more concrete is needed effectively, practically, and in the future. The strength of concrete is strongly influenced by the quality of the materials, admixtures, the working process, and the curing of the concrete. Concrete with the addition of an accelerator has higher compressive strength, this is due to the accelerator reaction which can accelerate the binding process and the development of the initial compressive strength of the concrete. Concrete with direct immersion treatment has large compressive strength. There are several methods of treating concrete, including watering and high temperature. This study used a fixed accelerator proportion of 3 % of the weight of cement with a test time of 7 and 28 days. The treatment method used is open space, immersion, high temperature at temperatures of 25 ºC, 30 ºC, 35 ºC, 40 ºC and 45 ºC. From the results of the research, there are differences in characteristics between normal concrete and concrete with the addition of an accelerator. Concrete with a high-temperature treatment method at a temperature of 45 ºC produces the highest strong pressure. This is caused by the higher the treatment temperature, the higher the rate of hydration process that affects the compressive strength of the concrete.","PeriodicalId":353803,"journal":{"name":"BERKALA SAINSTEK","volume":"30 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121010419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Observations on the morphological characters of plants were carried out directly in the field of tree ferns habitat at the Ijen geopark, Banyuwangi, while other morphological and anatomical determinations were conducted in laboratory. The tree ferns identified in the erek-erek forest were two species i.e., Cyathea contaminans and Cyathea orientalis. The main distinguishing characteristics of these species are: stem height, stem surface, attachment of the remaining petiole, scale color, crozier size, indusium and spore shape.

The use of pedestrian in Tunjungan Street is classified as high because it is a downtown area with various activities and its use as a pathway to access Cultural Conservation buildings. Many visitors use the pedestrian as an area to enjoy the Cultural Conservation building while walking along Jalan Tunjungan or as a photo point with the Cultural Heritage building in the background. This study aims to analyze the quality of pedestrian to determine the feasibility of infrastructure and pedestrians so that they can be an indicator of the completeness of pedestrian facilities in the Tunjungan Street Cultural Heritage Area. In this study, the problems that exist in the existing condition of the pedestrian path are investigated and studied regarding the quality of the pedestrian. The method used in this study was a quantitative method by assessing the quality of the pedestrian and scoring based on the Pedestrian Environmental Quality Index (PEQI) standard on both pedestrian sections of Jalan Tunjungan. This study indicates that the pedestrian in the Cultural Heritage Area of Jalan Tunjungan Surabaya meets the basic quality according to the calculation of the PEQI index with a total score of 60.77. This means that the pedestrian in the Cultural Heritage Area of Jalan Tunjungan Surabaya is suitable for use as a pedestrian that pays attention to the safety of road users for all.

The curriculum changes launched by the current government are also proof that the application of information technology in higher education is a must. Seeing this, universities have a difficult task, especially at the implementation stage of implementing information technology, because they must prepare not only infrastructure but also human resources who can develop good information system governance. Therefore it is necessary to carry out an IT governance audit. From the results of observations made, XYZ College has utilized information technology in academic services and other information services. However, it was found that information technology governance does not yet have a standard so that it is considered not to be able to meet the desired goals, and instead will cause various problems including uncontrolled operational costs and other problems. The purpose of this study is to measure the performance of information technology governance at XYZ College using the COBIT 2019 framework. Based on the results of an audit conducted from 7 EGIT components, namely processes, organizational structure, information flow and items, people skills and competencies, policies and procedures, culture, ethical behavior, and service infrastructure and application are on average at level 3, it can be concluded that the application of information technology has been running, the infrastructure is adequate but does not have good governance procedures or standards. It is recommended that XYZ Higher Education make standards for information technology governance as well as periodic evaluations of the use of all components of information technology, both software, hardware, and brainware.","PeriodicalId":353803,"journal":{"name":"BERKALA SAINSTEK","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126533899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
