Judul: Demographic Segmentation of Cosmetics Product Customers Based on CHAID Method
Abstrak: Chi-square Automatic Interaction Detection (CHAID) is one of decision tree method with chi-square criteria that will build non-binary trees based on a relatively simple algorithm. In this method, nominal, ordinal, and continuous data type can be used. However, the continuous predictors were splitted into categories with approximately equal number of observations. This research used CHAID method on building SHP Inc demographic segmentation. The sampling was performed to obtain relatively balance categories to produce a model that predict each category. There were three explanatory variables having structural linkage toward number of transaction variable. With depth equals to three, there were nine segments related to gender, age, and transaction period variable. These segmentation provided an overview about customers shopping pattern. Therefore, a more targetted campaign could be implemented perfectly according to the segmet characteristics.

Judul: Analysis of Chi-square Automatic Interaction Detection (CHAID) for Segmentation and Customer Targeting to Minimize Non-performing Loan
Abstrak: Banking plays an important role in the economy because it can increase growth and development, especially in the economic sector. Bank is one of the financial institutions or companies engaged in finance that carry out various kinds of services, such as providing loans, distributing currencies, controlling currencies, as a place to store valuable objects, finance companies, etc (Limbong et al. 2010). Credit is the most important thing in bank activities, considering that the largest income of a bank is obtained from the credit sector. CHAID analysis is conducted to identify potential customer segments based on the variables that have the most significant influence to credit status. SMOTE is conducted for managing unbalanced data with 600% oversampling and 117% undersampling. Based on CHAID analysis, the characteristics that characterize the variety of credit status were the loan term, the latest education, gender, age, and loan amount with 5% significant level. CHAID analysis produced 14 segments based on the independent variable associated with the response variable which in this case the response variable is credit status with a classification accuracy of 67.9%.

Judul: Penyebaran virus Newcastle-Disease (ND) pada burung liar
Abstrak: Banyak usaha yang telah dilakukan untuk mencegah dan mengendalikan terjadinya serangan wabah ND, seperti misalnya peningkatan sanitasi dan vaksinasi ND. Akan tetapi sam pai saat ini pengendaliannya belum dapat dilakukan secara tuntas. Banyak masalah yang menyebabkan kegagalan dari usaha untuk mengendalikan wabah ND, salah satu masalah yang perlu dipertimbangkan dalam penanggulangan wabah ND adalah sumber dan penyebaran virus ND oleh burung liar (Ronohardjo, 1980). Walaupun telah diketahui bahwa burung liar mempunyai peranan dalam penyebaran penyakit unggas, tetapi harus diakui bahwa sedikit sekali informasi mengenai jenis burung yang mempunyai potensi sebagai sumber dan penyebar virus ND. Selain menyebarkan penyakit unggas, burung liar juga dapat menyebarkan penyakit mammalia (Ottis and Bachmann, 1983). ...
