Abstract

Expert system is one of artificial intelligence engines that is using specific knowledge of an expert to solve a specific problem. In this study, the expert system is built to implement FLAG personality test using Modified Certainty Factor method in order to help counselee knowing his personality type and the careers suitable for him. Knowledge source for this system is obtained from the book Tes Bakat Anda (Test Your Own Aptitude) by Jim Barrett and Geoff Williams (2002) along with several consultations with Irianti Agustina, S.Pd., M.Pd. and Dra. Sri Rahayu Djami. This system is able to provide the output in the form of personality type of the counselee as well as career recommendations suitable for him. Based on study on 141 data of counselees, the results are: By using Modified Certainty Factor, this expert system has accuracy of 83.69%, and provides more certain output than the output provided by the conventional FLAG. Therefore, researcher recommends the using of Modified Certainty Factor method to improve any other personality test which still has not given certain output.

Abstract

The Case Based Reasoning (CBR) method is one of the methods to build a system that works by diagnosing new cases based on old cases that have occurred and providing solutions to new cases based on old cases with the highest similarity values. In this study, the authors apply CBR to diagnose diseases of children aged 1-12 years. Sources of system knowledge were obtained by collecting patient medical record files in 2014 and 2015. The calculation of similarity values using the Block City Gower method with a fairness value is 70%. This system can diagnose 10 illnesses based on 48 existing symptoms. The output of the system in the form of the illness experienced by the patient based on symptoms implanted by non-physician medical personnel, handling solution and presentation similarities with the previous case to show the truth level of the diagnosis. Based on the test of 83 new cases obtained system accuracy of 75,90%.

Abstract

Classification is one of the ways to organize text so that the texts with the same contents can be grouped in the same category. One of the famous text classification methods is the Naïve Bayes Method. Naïve Bayes has efficient computation and good prediction result however the performance of Naïve Bayes is not really good in classifying unbalanced dataset. This Naïve Bayes method is then modified to overcome the weakness, this modified method is then known as Transformed Complement Naïve Bayes (TCNB) method. In this research, TCNB method was used to the spam e-mails whose dataset were unbalanced and were consisted of 481 dataset in spam e-mail class, and 2412 dataset in legitimate e-mail class (in total, there are 2893 dataset). The classification was done with and without cross validation. The classification with cross validation was done starting from k=2 until k=10. The classification without cross validation was done by dividing the training data by 80% and testing data by 20%. The result showed that the classification by using TCNB with cross validation had its best accuracy level on k=10 by 93,917% and the classification without cross validation had its best accuracy by 92,760%. Thus it can be concluded that TCNB can handle unbalanced dataset with good prediction accuracy.

Abstract

Geographic Information System (GIS) is a special information system for managing data that has spatial information. In GIS is often used overlay techniques in merging 2 or more maps in to a unit ofland. In this research, the authors use the scoring method in determining the land suitability index. To get a unit of land done overlay on land type map, slope map, district boundary map, geological map and land cover or land use map. Scoring is done on temperature parameters, rainfall, dry moon, drainage, texture, effective depth, KTK, ground ph, n total, P2O5, K2O, slope, numbers of rock, and rock out crop. The calculationis done by scoring for each parameter based on the predetermined score class, the total of each unit of land will be used to determine the Land Suitability Index based on the classification class. The calculation result is done on 76 land (rice field and rainfed rice field). This test use Simple Linear Regression to find the closeness value between Land Suitability Index and rice produktivity. Linear correlation coeficient (r) obtained value r = 0,77 (positive correlation). The value of this correlation coefficient indicates the degree of closeness of the relationship between the Land Suitability Index and the productivity of the paddy. The value of coefficient of determination R = 0,59 = 59% indicates that 59% of the proposed variation of Y variable (paddy productivity) can be explained by X variable (Land Suitability Index) through linear relationship.

Abstract

Proceeding study to the college is something that most of twelfth grade students wants. However, they are still confused in chossing study program because due to not knowing their own aptitude and interest. To solve that problem, some factors are used, which are cognitive factor, by doing psychological test, and affective factor, by observing the tendency of their subjects in high school. Therefore, this research will design and develop a decision support system for study program determination in college using TOPSIS method. This method is chosen due to its capability in choosing best alternative out of multicriteria alternatives. Criterias that are used for this study includes Academic Criteria (Language, Logic, Science, Practice, and Social) and Aptitude Criteria (Intelligence, Space Reasoning, Mechanical, Abstract Reasoning, Verbal Reasoning, Numeric, Language Usage). The test is conducted through confusion matrix method. From 60 test-data, 13 data have difference between the system-result and real-result, thus the system is 78.33% accurate.

Abstract

The purpose of this study is to find out the influence between the use of the cooperative learning model of the JIGSAW and STAD . This study uses a quantitative method with an experimental approach. The population in this study were students majoring in computer science in the class of language theory and automata, and artificial intelligence. The sampling technique used random sampling techniques. In this study, the research samples were students majoring in computer science. Each class consisted of 33 students selected for the comparative experiment which were two classes. Testing is carried out using a one-way variant (one way Anova). The results of hypothesis testing showed the two data groups had the same variants between the STAD and JIGSAW learning models, with the value of Fcount of 0.5928 and Ftable of 1.79. It was found that Ftable> α, namely 1.79> 0.05, while Fcount> α, namely 0.5928> 0.05. By testing F, for the testing criteria, the value of Fcount < Ftable, (0.5928 <1.79) is obtained, then the accepted hypothesis is H0, meaning that the two data groups have the same variants. So it can be concluded that the application of the STAD and JIGSAW models has an effect on the achievement of student learning outcomes.
