Heart disease is a disease with a high mortality rate, there are 12 million deaths each year worldwide. This is what causes the need for early diagnosis to find out the heart disease. But the process of diagnosis is quite challenging because of the complex relationship between the attributes of heart disease. So it is important to know the main attributes that are used as a decision making process or the classification process in heart disease. In this study the dataset used has 57 types of attributes in it. So that reduction is needed to shorten the diagnostic process, the reduction process can be carried out using the Principal Component Analysis (PCA) method. The PCA method itself can be combined with data mining calcification techniques to measure the accuracy of the dataset. This study compares the accuracy rate using the C5.0 algorithm and the Naïve Bayes Classifier (NBC) algorithm, the results obtained both after and before the reduction are Naïve Bayes Classifier (NBC) algorithms that have better performance than the C5.0 algorithm
Indonesia is a maritime country that is located on 3 plates of the world or commonly called the Ring of Fire which causes frequent earthquakes. The earthquake is the biggest threat faced by the potential of the tsunami in it which can cause damage and even cause casualties. Data mining can explore pre-existing earthquake data and draw a pattern or conclusion from a database. The Naïve Bayes Classifier (NBC) algorithm is part of the data mining classification technique that is used to estimate or predict the chances of a possibility occurring. Based on the results and discussion, conclusions can be drawn by applying the Naïve Bayes Classifier (NBC) algorithm on earthquake data to potential tsunamis in Indonesia to find out the possible effects of earthquakes. With the testing data used the effect produced is the Potential Tsunami.
PT. Pos Indonesia is one of the State-Owned Enterprises (BUMN) which is engaged in shipping services. To face this business competition, a company must improve the quality of service to obtain customer satisfaction and maintain the smoothness and progress of the business. The improvement of the service process for the company cannot be separated from the role and contribution of a manager in the company. So that the feasibility of the performance of a manager must of course be considered and also assessed. To see the feasibility of a PT. Pos Indonesia manager doing a performance assessment. To get accurate performance appraisal results, a decision support system is carried out using the WASPAS method. Where the WASPAS method is considered appropriate to determine the best technician because it performs ranking based on predetermined criteria values. It is hoped that this research can help get effective results. In the study, it was found that managers were still eligible to be in the occupied positions
<em>Indonesia is a tropical country which consists of summer and rainy season. During the summer the room temperature will be high, so that will cause people who are in the room will feel uncomfortable or hot. To create comfortable conditions, air conditioning is needed. SPK is part of a computer-based information system. There are several stages in the decision support system, namely defining the problem, collecting relevant and appropriate data, processing data into information, and determining alternative solutions. The number of AC products on the market makes people feel difficult in choosing the right AC so that a decision support system is made. The VIKOR method focuses on ranking and choosing from a set of samples with conflicting criteria, which can help decision-makers to get a decision.</em>
The success of a university is not only seen from the role of Educators (Lecturers) but also the role of Education Personnel (TENDIK). Educational Personnel (TENDIK) includes Administrative Personnel in universities. Work performance is the main factor of the success of higher education performance. The results of good work given will have a good impact on universities. TENDIK who excels are also competent in higher education and contributes to the joint progress of both TENDIK and universities. Apart from lecturers, TENDIK is also an asset owned by universities. Rewards or awards given to TENDIK can be done by assessing the performance results of each TENDIK. The reward given to TENDIK is a form of appreciation for the performance carried out at the university. Giving rewards to TENDIK must be based on a proper and accurate performance assessment. The problem is that there is no definite reference used to evaluate the performance of TENDIK in giving rewards. The performance assessment carried out must be objective, of course, with an objective assessment the results obtained from the TENDIK performance assessment will not be a problem for other TENDIK. Decision Support System is a computer-based information system that is used to assist in decision making by utilizing certain data and models to support a solution in solving a semi-structured and non-structured problem. SMARTER is one of the methods in the Decision Support System that provides recommendations to decision makers based on relevant criteria, which in determining the criteria and sub-criteria and their weight values use ROC (Rank Order Centroid). Of the several criteria used for the selection process using the alternative SMARTER method with the name A4 with a final utility value of 64.25%
