Abstract

The stored Data in Data base is generally not fully utilized. The school conducts promotions every year for new student admission while there is no being known effectively level of carried out promotion. Its database can be used for finding out the new student profiles by using two step clustering method deemed to have mixed data types namely numeric and categorical data types. The clusters that are formed are then analyzed to be able to identify the right promotional strategies. The researched data are some new student data in 2015, 2016 and 2017 students are totally 1399 people, with the Processing Standard for Cross Industry-Data Mining (CRISP-DM) methodology which consists of six stages, which are Business Understanding, Understanding Data, Preparation Data, Modeling, Evaluation and Deployment.
Through the preparation data variable stage used into eight variables namely gender, religion, father's job, mother's job, parents income, department code, distance to school and junior high school distance. The mixed data is running with two step clustering methods.In this Research, the data is grouped into two or four clusters with three variable schemes so a total of nine schemes that the naming schemes begins in 1.2 until 1.4 for 8 variable, 2.2 till 2.4 for 6 variable, then 3.2 till 3.4 for 5 variable. The calibration for the amount of different clusters and variables is objected to obtain for the ideal cluster to depict the proper profile through the promoting strategy which is recommended to the school.
The result shows that new students with the largest are dominated by male in majoring TKJ, moslems; the range distance 6.25 ? 6.29 kilometers, Junior School distance at around 12.61- 12.69 kilometers, and entrepreneuring father position with mother of housewife position among salary at Rp. 2.000.000- Rp. 4.999.999,-. Whereas the smallest cluster is dominated by female in majoring Accountancy, male in majoring RPL and TKR, the range distance at 5.11-736 kilometers, school range distance at 8.16-20.12 kilometers, enterpreneuring father position with housewife of mother position among salary at Rp. 2.000.000-4.999.999 in majoring Accountancy, Rp. 1.000.000-1.999.999 in Majoring RPL, and Rp. 500.000 - 999.999 for TKR Major.
