This is certainly less efficient and less effective because it requires time and energy to do it. One solution is to make a control device it works automatically ie using a microcontroller, Bluetooth, and servo motor, with communication devices Android-based handphone. Laboratory experimental methods have been carried out to make 'open and close tools the gate with a cellphone'. Based on the results of the trial using Bluetooth and mobile phones, this tool can work up to a distance of 11.5 meters with a response time of 1 second. This prototype tool is very cheap, practical, efficient and effective in opening and closing gates. Not all Bluetooth can open and close gates because the password is required for the accent.

A system is needed to produce a number of classes so that it can reduce the number of opening classes because the demand for a higher number of classes is in the class because of the interest in a class that will be opened. Fuzzy methods are used to predict students who will repeat the course based on student force and value variables. The K-Means method is used to classify the subjects with the number of students converted into 2 groups based on the number of students who have been taken and the number of students who repeat a number of subjects.

In the testing phase, the inference process using approximate inference was carried out and the accuracy was nearly 100% for all testing scenarios. The application of this method could result in a representative Bayesian network. Its resulted structure was affected so much by data condition, thus data cleaning was important to do before the training and testing phase.&nbsp;</span></em></p> 2019-10-05T00:00:00+00:00 ##submission.copyrightStatement## https://stt-pln.e-journal.id/petir/article/view/468 Implementasi Metode FIS Mamdani Pada Aplikasi Jadwal Mengajar Guru Di SMK Adi Luhur 2 Jakarta 2019-10-22T04:33:01+00:00 Imam Sunoto raidersimam@gmail.com Lukman Lukman lkmnaja51@gmail.com <p style="text-align: justify;"><em>Scheduling subjects in a school can support, facilitate and enhance the quality of a school. Subject scheduling generally functions for activities in facilitating the quality of teaching teachers and students in order to create discipline in school performance activities. Along with increasing hours of subjects that require precise and fast accuracy in processing data can also speed up time. In general, the data processing of scheduling subjects at Adi Luhur 2 Vocational School 2 is still done manually and there is often a lack of schedule due to the teacher being absent or teaching in school, so a computerized information system is needed where everything can be done correctly. For that we need a system that can determine the scheduling of subjects so that there is no conflict with other teaching schedules. In this study, Mamdani's fuzzy infrence system (fis) logic is used. With the existence of a teaching schedule management system with fuzzy mamdani method approach more accurately in accordance with the best conditions of the teacher concerned. The results of this study are in the form of a prototype that can process input in the form of teacher's willingness to arrange teaching schedules at Adi Luhur 2 Vocational School Jakarta.</em></p> 2019-09-26T00:00:00+00:00 ##submission.copyrightStatement##
