Abstract

Data Mining is a series of processes to explore added value in the form of knowledge that has not been known manually from a data set. This grouping aims to determine the level of student success in the learning process that has been carried out. The approach used is quantitative. The subjects of this grouping are Class X (Ten) Academic Years 2018 to 2020. The data collection technique used is the learning outcome test. This grouping is done using Data Mining Rapid Miner 5.3 software, where the results will prove that the results of the evaluation of learning achievement are carried out by applying the C4.5 Algorithm. The results obtained are an accuracy value of 71.43%, meaning that the resulting rule is close to 100% correctness. Where the results of the Class Achieving precision label is 63.89% and the label Not Achieving is 92.31%. In accordance with these provisions, the results of manual calculations with Rapid Miner testing produce 11 models of rules or rules for Student

Abstract

Four-wheeled vehicles become the needs of society is quite important at this time, can be seen from the density of traffic every day. Type of four-wheeled vehicles are also very varied, among others, Honda, Izusu, Toyota, Mazda, and many more, therefore there are still many people who are confused when wanting to buy a car. People who want to buy a car also often ask for help or advice from others to choose what car is suitable for the buy. Many aspects must be considered in buying a car, then people who are often confused to choose because it is faced with the large selection of types of cars in the Sorum. I am here to provide a short solution how to choose a car that according to the will and our individual tastes using the method.

Abstract

Abstract− ecision support system is a computer-based system that can help decisions to solve certain problems by utilizing certain data and models. Many cases can be used as research in decision support systems, one of which is determining the best Vivo promoter. In this research, a decision making system will be designed using the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method. The TOPSIS method is a multi-criteria decision making method that uses the principle that the chosen alternative must have the shortest distance to the positive ideal solution and the farthest distance to the negative ideal solution. The steps used in the TOPSIS method are the normalization matrix calculation process, the weighted normalization matrix calculation process, the process of determining positive ideal solutions and negative ideal solutions, the process of calculating the distance of each alternative to the ideal solution, and the process of calculating the preference value of each alternative. The results obtained from this study are in the form of the best vivo Pramotor data in one month.Keywords: Decision Support System, TOPSIS, Best Vivo Pramotor

Abstract

Washing hands with a handsanitizer can inhibit growth and kill bacteria, viruses and fungi. The aim of this study was to analyze the determination of the best handsanitizer based on consumer choice. The data collection method is done by interviewing consumers who use handsanitizer in Pematangsiantar city. Based on these results, it can be obtained the assessment criteria for Material Content (C1), Type (C2), Aroma (C3), Availability of Goods (C4). The alternatives used are 4, namely: A1 = Dettol, A2 = Antis, A3 = Nuvo, A4 = Lifebouy. The results of research using the EXPROM II method show that the Dettol (A1) handsanitizer product with a value of 1.1594 is recommended to be the best handsanitizer product based on consumers. It is hoped that the research results can provide information to consumers in determining the best handsanitizer based on predetermined criteria and alternatives.Keywords: Decision Support System, EXPROM II, Handsanitizer

Abstract

Pematangsiantar City is one of the regions in Indonesia which has a land area of ​​79.97 KM2. the office of the National Land Affairs Agency is a non-ministerial government institution in Indonesia that has the task of carrying out government duties in the land sector in the city of Pematangsiantar and providing land certificates for the community. A system for predicting the need for blank soil certificates using the Artificial Neural Network method is a method that is able to perform a mathematical process to predict the need for blank certificates for soil certificates using the backpropagation algorithm for data processing implemented with matlab. Data were collected through direct observation and grouped based on the annual need for blango factors. The results obtained from the test are the performance and epoch values ​​where each architecture is not the same. The test results are displayed in the form of a graph comparing the target value with the training and testing process.

Abstract

The purpose of this study was to determine the flood vulnerability in the Mandailing Natal Regency. In this study, researchers used the Artificial Neural Network method with the Backprogation algorithm. Artificial neural network method is a method that is able to perform mathematical processes to predict flood-prone areas with backprogation algorithms for data management that is applied by matlap. The data source used is direct observation in the area of Mandailing Natal Regency. The data will be managed based on flood disasters that occur every year. The results obtained from the test are performance and epoch values where each architecture is not the same, the test results are displayed in the form of a graph comparing the target value with the training and testing process.
