Abstract

The selection process in determining the scholarship recipients still experiencing problems. In the field was found less like the scholarships are caused by a system that is still a conventional or manual. In addition, decision makers can’t see these criteria in a scholarship. In computer science, there is a system that can help decision makers to address the problem of the nature of the spring the structure or lack of structure the system of supporting the decision. In Support System's decision there are various methods of one of them is the method of Analytical Hierarchy Process (AHP) who was found by Thomas L.Saaty. AHP own can help in determining the priorities of some criteria with analysis, the comparison of pairs of each criteria that have been found. By looking at problems in decision-making in the selection of scholarship recipients, a support system decisions by using the method of AHP is right to use in helping to make a decision to determine the recipient of the scholarships. It is hoped that results in this research may help decision makers in determining the scholarship recipients. Keyword: Selection, Computer Science, Support System Decision, Method AHP

Abstract

The Smart Indonesia Card (KIP) College policy was launched by the government under the auspices of the Ministry of Education and Culture (Kemendikbud) through the National Team for the Acceleration of Poverty Reduction (TNP2K). The aim of this program is to help poor students to obtain a decent education, prevent students from dropping out of college, and to fulfill their college needs. It is hoped that this assistance will be used by students to meet college needs such as transportation costs for students to go to college, costs for college equipment, and pocket money. With the Smart Indonesia Card, it is hoped that no more students will drop out of college due to lack of funds. The Smart Indonesia Card (KIP) funds are given to students who are less able to continue their studies. Keywords: Classification, Naïve Bayes, Rapid Miner, Smart Indonesia Card

Abstract

High rainfall can cause natural disasters such as floods, landslides and flash floods. This phenomenon has become more frequent and more severe in recent years, and Indonesia as a tropical country is very vulnerable to natural disasters caused by extreme weather. The Meteorology, Climatology and Geophysics Agency (BMKG) notes that the high number of hydrometeorological disasters cannot be separated from climate change. The BMKG Climate Variability Analysis Coordinator said that BMKG monitoring results in the last 40 years indicated that extreme rainfall in Indonesia had an increasing trend, both in terms of frequency and intensity. The causes of disasters due to rainfall are climate change, population growth and urbanization which increase the risk of natural disasters. Climate change causes rainfall to become more irregular and intense. Population growth causes an increase in settlements in areas that are vulnerable to disasters, so that the risk of disasters becomes higher. Urbanization also causes a reduction in the area of natural areas that can absorb rainwater, resulting in floods and landslides. According to data obtained from the Indonesian Disaster Information Data site (https://dibi.bnpb.go.id/) there were 2690 floods, 2228 landslides and 272 droughts that occurred in Indonesia in the period 2017 to 2018, and landslides is the most common disaster, in 2020 there were 3,232 landslides recorded in West Java.

Abstract

A company must be selective in conducting employee assessments in order to retain employees with the best performance. In assessing employee performance, it can be seen from diligence and discipline. But in reality, employees' good performance sometimes gets bad reviews and even a warning from their superiors. This is caused by the employee assessment monitoring system used, namely only personal assessment without using an assessment system and the data collected is not optimal. Seeing the problems above, the author conducted research using the Naive Bayes method to carry out data processing using data mining algorithms to obtain predictions that can be used as additional references in employee performance assessment decisions for contract extensions. Naive Bayes is a data processing algorithm that is classified as a calculation that is easy to understand but whose accuracy results are reliable. The author also uses the Rapidminer supporting application to test the accuracy of the system created. Testing was carried out by preparing 320 data and testing data of 50 randomly selected data. The testing data will be analyzed using the Rapidminer supporting application. The test results produced an accuracy of 83.96%. Keywords: Employees, Assessment, Data Mining, Naïve Bayes Algorithm

Abstract

The world of education is currently developing very rapidly. In this rapid development, along with the development of technology and information that occurs. This very diverse technology and information requires quality improvements and mechanisms for the service sector to be more efficient, so that the Human Resources (HR) that have been produced from the world of education can make a contribution to the process of building the outside world in accordance with their expertise. When the data processing and academic data information system is running, it is still done manually so that it is possible to cause efficiency problems with time in the data processing process. To overcome these problems MI Miftahuddiniyah requires a web-based academic information system. The goal is to minimize errors and provide convenience to the school academics in processing data. The development method used in this information system is using the waterfall method, where the steps of this method begin with an analysis of system requirements, and continue with material collection, design, manufacture, testing (redesign if not appropriate) and system application. The results of this study are in the form of a website for the MI Miftahuddiniyah Academic Information System. The development of this Academic Information System is made in a web-based application that can make it easier for admins to process report data management, minimize errors and data loss because the processed data is stored in the database, and can speed up the process of inputting student grade data.

Abstract

ASF Sport Gear Shop is a sports equipment shop that sells various sports equipment, and sports accessories for women or men sports equipment that includes several categories including t-shirts, jersey, soccer jackets, soccer shoes, futsal shoes, running shoes, sneakers , and hat. Asf Sport Gear is one of the stores whose buying and selling process still uses a manual system. In the process of selling goods, it is usually still written in sales books or notes only. In the process of knowing the stock of goods in the warehouse also must check one by one. Therefore, an information system is made for ASF Sport Gear. The system is made in order to help speed up the work completion process. In the sales process, making the memorandum is automatic, so it does not need to be written in the book. Checking stock of goods can be known quickly without having to check one by one. Thus the system can improve the performance of ASF Sport Gear. This research provides a solution to the problem for the store, as one of the fields of business that is needed by the use of computer methods as a means of transaction activities..
