Majors are held no valid high school in Indonesia is conducted when students are still in grade X. This includes the areas of interest Majors Natural Sciences, Social Sciences, and science of language. Majors will depend on the capability of student achievement in the areas of interest / courses available and in accordance with the conditions at the school. If it is not possible then the only department of particular interest are provided in school. The results of tests that tested students' interest through psychological tests aimed to help the school and the students themselves so that later, the lessons will be given to students become more focused as it has in accordance with the capability in the field of interest. Fuzzy C-Means algorithm is an algorithm that is easy and is often used in the technique of grouping the data as it makes an estimate efficient and does not require a lot of parameters. Several studies have concluded that the Fuzzy C-Means algorithm can be used to classify data based on certain attributes. In this study will be used Fuzzy C-Means algorithm to classify the student data High School (SMA) based on the value of the core subjects for the majors that are appropriated to the interests test results. The study also examined the level of accuracy of Fuzzy C-Means algorithm in determining the majors in high school. Application of Fuzzy C-Means algorithm in determining the majors in the 278 high school students were tested in this study, indicating that the FCM algorithm has a good degree of accuracy (in an average of 82.01%) by including interest test scores compared with the manual method based on the selection of individual students only 63.67%.

Dalam proses speech recognition, speech syntesis dan speech enhancement, signal suara yang diinputkan tidak dapat langsung dikenali atau diindentifikasi sebagai gelombang signal voice atau unvoice. Proses analisis ucapan dalam menetapkan voice dan unvoice biasanya dilakukan dengan ekstrasi dari speech signal atau signal suara. Dalam penelitian ini, kami melakukan dan membandingkan 3 akurasi metode yakni: penentuan manual dengan software Adobe Audition dibandingkan pada tool matlab dengan metode separation of voice and unvoice using non overlapping block, zero-crossing rate and energy of a speech signal, dan juga membandingkan dengan metode peneliti yaitu penggabungan teknik overlapping blocks, zero crossing rate dan short time energy dalam menentukan voice dan unvoice untuk memisahkan bagian unvoice dan voice ucapan dari sinyal suara. Dengan ada perbedaan pada overlapping block dan non-overlapping block. Kami mengevaluasi hasil dari semua metode tersebut bahwa teknik yang digunakan peneliti dengan overlapping blocks, zero crossing rate dan short time energy terbukti lebih efektif dalam pemisahan voice dan unvoice.
