Kata kunci: Data Mining, Klasifikasi, Algortima C4.5; feature selection, bidang minat Abstract At the faculty of computer science at a university there is an undergraduate program of Informatics Engineering which is divided into two areas of interest, namely intelligent systems and software engineering design. For the selection of areas of interest, students have difficulty determining their areas of interest. In dealing with this, it is necessary to have ideas that can recommend students to choose their area of interest. In this case, an appropriate method or algorithm is needed based on the data criteria to be used as a variable. The method or algorithm that will be used in this research is the C4.5 algorithm based on forward selection. The C4.5 algorithm is a classification algorithm from the branch of data mining. The classification method will make decisions based on the selected data attributes. The results of the classification of the selection of areas of interest use balanced data and attributes that have been selected for several features and cross validation iteration is carried out to produce the right accuracy. Based on the results of testing with two methods, testing using only the C4.5 algorithm produces an accuracy of 84.33% and for the C4.5 algorithm based on forward selection it produces an accuracy of 85.00%. There is an increase in accuracy with the addition of a selection feature. Keywords: Data Mining, Classification, Algorithm C4.5; feature selection, areas of interest

Course scheduling (timetabling) an assignment of courses and lecturers in the available time slots involving certain restrictions. Simulated annealing is a heuristic method can be used as search method and provide acceptable solutions (objective function) with good results. In this study discusses the scheduling of courses at the college using simulated annealing using five variables data that lecturers (X1), courses (X2), the time slot is comprised of the day (X3) and the time period (X4) and class room (X5). This study has two objective functions to be generated, the first is the assignment of a lecturer on courses that will be of teaching, second lecturers and their assignment course on the time slot and the room available. The objective function is calculated by taking into account the restrictions involved to produce the optimal solution. This study tests the simulated annealing method with an varian average of 77.79 % of the data variance can reach a solution with a standard deviation of 3.93. In this study, given the method of solution in the use of the remaining search space to be reused by the data

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Full text linkCovid-19 pandemic has made changes in behavior in all aspects of human life, especially in the field of education. Proper handling of the outbreak is needed to break the chain of the spread of COVID-19. One method that can be done is to perform early detection of symptoms of patients exposed to COVID-19. The learning process will be carried out offline, strict supervision is needed to maintain health protocols. Therefore, to minimize the spread of covid in schools, this system is needed. In September 2021, face-to-face learning in schools has begun. Learning is carried out with full health protocols and minimizes the spread of COVID-19. The Indonesian government has taken several ways to deal with this outbreak, starting from spraying disinfectants, urging the public to practice social distancing, conducting mass rapid tests, to buying medical equipment. Many parties have assisted the Indonesian government in tackling this epidemic in several ways, through donations in the form of money, medical equipment, personal protective equipment (PPE), and much more. Application of IoT for Body Temperature Detection System and Oxygen Levels for Ar Ridho Middle School Students Using Android Technology. This solution is expected to be effective in suppressing the spread of COVID-19 which may occur during face-to-face learning in schools. And this solution is expected to become a new health protocol for face-to-face learnin
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
