Abstract

Abstract Alpha Cronbach and Kuder-Richardson reliability coefficients are also called lower bound coefficient. From score structure, it is found that respondent score variance and item score variances are together related to the covariance of the item intercorrelations which in turn is also related to the item equivalences within the test. A deviation from these equivalences can disrupt this reliability coefficient and hence it is called lower bound coefficient.

Abstract

E-recruitment is a web-based application that is used to recruit employees for several available companies. The e-recruitment system has a plagiarism checker feature. Plagiarism itself has the meaning of actions that are considered fraud by taking someone's idea or writing without mentioning a reference and claiming it as their own. So that the e-recruitment application requires a plagiarism detector which functions to make it easier for companies to assess the characteristics of their prospective employees. The plagiarism checker feature applies a string matching algorithm to a text to search for common words between texts. There are several algorithms used for string matching, two of which are the Rabin-Karp and Jaro-Winkler algorithms. The Rabin-Karp algorithm is one of the algorithms that is suitable for solving multi-string pattern problems, while the Jaro Winkler Distance algorithm has advantages in terms of accuracy. An e-recruitment application with a plagiarism detection feature is developed and tested on various types of text, namely in the form of a self-description text of the prospective employee. From the experimental results, it was found that the two algorithms can be used to detect plagiarism in the applicant's self-description text, but it still has shortcomings in checking it.

Abstract

Graduating from college is something that students really want. By graduating from college, it has become a sign for a student to become a worthy scholar to continue and enter the next level. Graduation time is influenced by the academic value obtained from a student. If a student gets a high score, the student's graduation will be faster or on time. On the other hand, if a student gets a score below the average, the student's graduation time will be longer. At this time, one of the causes of students getting low grades is because students who are so busy playing games neglect their lectures and lose concentration while studying. So this can affect the time of their graduation. Students should be able to control themselves to manage their time playing online games and lectures in order to complete their obligations as a student, and students who get low grades for playing games should also be aware that getting low grades continuously will result in the student being threatened with dropping out (DO).Therefore, an information system program was designed that can be used by students who like to play games to be able to predict their graduation time so that they can find out their graduation time. The design of this program applies the K-Nearest Neighbor method which is a classification technique for objects based on learning data that is closest to the object.The final result of the application of the K-Nearest Neighbor method in the program has its advantages and disadvantages. The classification process is strongly influenced by the large amount of training data, and the determined value of 'K' (neighbors). The more the amount of training data, the level of accuracy can be reduced. The level of accuracy in testing using training data is 230 data, and using test data as much as 30 data with several specified 'K' values, namely, 2, 3, 4, 10. Accuracy results with 4 K values used can reach an accuracy rate of 90% .

Abstract

Malaria is one of serious threat that still lurking in Indonesia. In 2013, there are as many as fifteen provinces that exceeded national malaria’s prevalence number. The making of Decision support system for identifying malaria is targeted to lower malaria cases and reduce the risk of being late in handling malaria due to lacking of knowledge about malaria disease. This system is designed to count one’s odds (in percentage) of being infected by malaria. The DSS itself will be using Naïve Bayes method that is derived from probabilistic theorem of Bayes’.
