SISTEM PENDUKUNG KEPUTUSAN PEMILIHAN MAHASISWA BERPRESTASI BERBASIS WEB DENGAN METODE FUZZY QUERY

Student Selection and determination to achieve a long and complicated process. The selection process is to have many opportunities to make wrong decisions because the process of selecting students based on subjectivity. This means most likely that the best students are chosen does not achieve the desired standard and not getting the best candidates. Therefore made a decision support system that can perform the calculation on all the criteria for selection of student achievement in accordance with real data. This final project will implement the fuzzy logic into the query, called the Fuzzy Database Query. That is, a query that has a variable-valued fuzzy variables. The problems will be resolved is the selection process on academic merit. Fuzzy method used is the Mamdani fuzzy query model. Students who will be recommended to student achievement has a valuable criteria fuzzy or non-fuzzy value. Fuzzy criteria required GPA among others, training, intra-extracurricular activity, Essay. While non-fuzzy data needed among other majors and years of data. Results from this system in the form of a list of student achievement consistent with real data on academic merit Electronic Engineering Polytechnic Institute Surabaya. The final project is built using the MySQL database and PHP programming language. Key Word : Logika Fuzzy, Himpunan Fuzzy, Fuzzy Query Database, Student achievement

Learning Strategies Used by Students of Chemical Engineering of UMS to Learn Materials in English

This research is aimed at showing the differences of learning strategies used by high and low achiever students of Chemical Engineering of Muhammadiyah University of Surakarta. The subjects of the research are six students, three of them are high achiever students and the three others are low achiever students. This research is done by classifying the data using the learning strategies classification conducted by O’Malley and Chamot. The type of this research is case study. The data are obtained from the interview and document to the subjects. The result of this research shows that the subjects use various learning strategies classified by O’Malley and Chamot in learning materials in English. Those learning strategies used by the subjects are similar and the others are not. Although they use same strategies, some of those strategies are implemented differently. The differences of learning strategy used by the subjects are in metacognitive and cognitive strategies. The learning strategies that are only used by high achiever students are: advance organization (metacognitive strategies), grouping, auditory representation, and transfer (cognitive strategies). The other learning strategies are used by both high achiever and low achiever students, even by one student of each achiever. Beside the differences in learning strategies used by high achiever and low achiever students above, there are some strategies that are implemented differently by those subjects. The differences in implementation can be seen in metacognitive strategies (organizational planning, self-monitoring, self-evaluation, and self-management), in cognitive strategies (resourcing and elaboration), and both of the socioaffective strategies
