<p>SMA PGRI 1 Subang is a private school that has several missions, one of which is the establishment of academic and non-academic achievements. In an effort to achieve the mission must supervise student achievement. The effort he did was to provide understanding in the selection of majors in accordance with the interests and talents of students. But in the activity of providing understanding, the school does not yet have a model that can evaluate the interests and talents of students to choose majors. The model can be obtained using student data processing. Data processing can be done using data mining, namely data mining clustering techniques. The technique will produce a model in the selection of majors. This clustering process is the process of grouping similar data based on the similarity of data held by students. The research method used is the CRISP-DM method which has 6 stages consisting of: Business Understanding, Data Understanding, Data Processing, Modeling, Evaluation, and Dissemination. The data that is processed is 620 data consisting of class of students in 2014, 2015, 2016. The results of processing using clustering obtained 6 clusters that have different models for each cluster. The results of this study can be used by schools in recommending courses chosen by students according to students' interests and talents, so students can learn optimally.</p><strong><em>Key words</em></strong>: clustering, dataMining, suitability, majors, students

Pendidikan selain diarahkan untuk mencerdaskan siswa dari sisi akademis, juga dimaksudkan untuk menghasilkan pribadi unggul dan berintegritas. Karenanya maka pendidikan sejatinya terus mengasah kejujuran setiap siswa sejak perencanaan, proses dan evaluasi akhir. Demikian juga dalam pembelajaran matematika yang relatif memiliki perhatian pada  pemahaman konsep dan keterampilan pemecahan masalah. Pengembangan evaluasi pendidikan khususnya dalam pembuatan soal-soal matematika berdasarkan bilangan unik siswa diharapkan membantu para guru dan juga sekolah mempersiapkan generasi muda yang memiliki karakter jujur dan bertanggung jawab.  Adapun pengembangan Template Microsoft Excel diharapkan dapat membantu pembelajaran matematika semakin efektif dan efisien khusunya dalam evaluasi pendidikan mata pelajaran matematika berdasarkan bilangan unik siswa bagi para guru. Tujuan dari kegiatan ini antara lain membantu para guru Madrasah Tsanawiyah se-KKM (Kelompo Kerja Madrasah Tsanawaiyah) VII Kabupaten Garut dalam melakukan evaluasi pendidikan pembelajaran matematika dengan memanfaatkan bilangan unik siswa. Para guru mata pelajaran matematika mendapatkan pelatihan bagaimana cara merancang Template Microsoft Excel dalam mengevaluasi pendidikan pembelajaran matematika yang berdasarkan angka unik siswa. Template Excel yang dikembangkan dapat memudahkan para guru dalam mengevaluasi pembelajaran matematika dan akan memberikan informasi yang lebih akuratn genai perkembangan belajar siswa.

The radiation pattern is an important parameter of the antenna performance. This parameter needs to be measured not only accurately but also as fast as possible. For this purpose, the automatic measurement system has been developed. In this research, the system is implemented to analyze the radiation characteristic of a Yagi antenna by measuring its radiation pattern. The measurement result of the patterns is compared to those of the table characteristics of the Yagi antenna as well as a computer simulation. For this purpose, a Yagi antenna is designed and realized as the radiation pattern measurement object. Then, the students experiment to measure and analyze the effect of parasitic elements on the radiation pattern performance of the antenna. The questionnaire is carried out as the method of the research and directed to the students of the Telecommunication Study Program, Bandung State Polytechnic, to get the perception of the object performance.
