Completeness of data in each institution, such as major in a university, is necessary. Data of former school has important role in the need of students data. However, there is no relationship between data of former school and variable of students score. The suitable classification used in this research is data mining technique which is nave bayes algorithm. This algorithm is able to manage massive data with a relative fast timing. By using this algorithm, the data results 64.77% performances in classifying former major in school towards variable of score. Hence, the researchers optimize selection feature by using Backward Elimination and result 71.71% performances data. It concludes that performance increases with selection feature. The increasing shows that not all variable of score affects the former school major.

Setiap Perguruan Tinggi mempunyai mahasiswa baru yang berasal dari berbagai sekolah menengah atas dan juga sekolah menengah kejuruan. Seperti halnya pada program studi teknik informatika fakultas ilmu komputer di Universitas Dian Nuswantoro. Program studi ini mempunyai mahasiswa terbanyak di Udinus, sehingga perlu selalu diadakan evaluasi. Dalam hal ini evaluasi yang dipilih adalah tentang asal jurusan sekolah mahasiswa dengan variabel nilai mata kuliah. Dengan mengambil mahasiswa dari angkatan tahun 2010 sampai 2012 sebanyak 10030 mahasiswa, hanya 489 mahasiswa yang mengisi asal jurusan sekolah. Dari sejumlah mahasiswa tersebut dilakukan preposisi dengan mengambil nilai mata kuliah wajib sebanyak 25 mata kuliah dan asal jurusan sekolah. Teknik data mining berupa algoritma naive bayes dioptimasi dengan fitur selesi forward selection telah meningkatkan akurasi dalam penemuan pola klasifikasi. Peningkatan akurasi dari naive bayes 64,77% menjadi 78,08% setelah dioptimasi dengan forward selection. Dengan demikian hasil klasifikasi tersebut bisa digunakan sebagai informasi dalam metode pembelajaran yang bisa diterapkan.Kata kunci: data mining, forward selection, naïve bayes.

Routine events required by tertiary institutions require escort from selected security guards. Elections based on personal subjectivity will lead to results that are not in accordance with the purpose of the security itself. However, if the selection is based on the objectives will give results that are in accordance with professionalism. Each security unit has a different level of importance, so that at the level of security the event needs a level of professionalism in accordance with the level of importance at the college level. In detail the selection of security units on several criteria, namely event, years of service, cooperation, service, personality, skills and responsibilities. The method used in this selection process is the K-Nearest Neighbor, with the final result approval rate ofÂ 0.88%

The level of service in an agency is a supporter of the survival of an agency. consumer goals that arise from good service quality, are believed to be the main factors of business success. The indicator of the level of customer satisfaction with service quality is when consumers get maximum results from a desired need. Consumer measurements can be seen from the results of the buyer's assessment given by the service manager, and services in the form of consumers which result in goods or services being used as drivers. The method that will be used in the process of ranking consumer satisfaction variables in this study is Simple Additive Weighting. This method has a work order sequence by determining the weight value of each variable, then the ranking process by determining the best variable from the consumer satisfaction variable. The final result of this research is the ranking of consumer satisfaction variables from the highest to the lowest using Simple Additive Weighting to obtain an accuracy rate of 90%. The variable "satisfactory taste" turned out to be the highest satisfaction service variable, meaning that the cafe service party needed to maintain the taste so that consumers were satisfied with the existing services.
