In 2018, Telkomsel's core business shifted its main services from Telephone and SMS services to Data and Digital services, since a declining trend of revenue starting 2014. However, telephone service still contributed 28.4% to the revenue and was the second largest, while SMS gave 4.1%. This research predicts voice package buyers using predictive analytics to identify customer profiles and significant variables to form appropriate target customer segmentation. Logistic regression was used to predict customers who would buy voice packages using 15 input variables. Next, analytics was done by dividing the data into 70% training data sets and 30% testing data obtained from customer voice package user data. The model accuracy gained 97.2%, and the top seven significant variables were formed. Then five clusters of customer segmentation were formed based on top significant variables using the K-Means clustering technique. Based on the results of the prediction model and clustering, behavioral targeting was conducted to provide targeted gimmick products based on five segmentations formed, and then it was divided into two main target customers by considering the similarity of behaviors based on revenue voice, minutes of voice usage, voice transactions, day of voice usage and data payload, thus it was more targeted.

This study aims to determine the effect of ethnocentrism, animosity, product country image, and brand image on the willingness to buy Chinese car products. Data were collected from Chinese car users and potential car buyers. The purposive sampling technique was chosen in this study, which resulted in 300 respondents for analysis. Data were analysed using exploratory factor analysis and structural equation modelling. The results showed that ethnocentrism had a significant positive effect on animosity and had a significant negative effect on brand image, animosity had a significant negative effect on willingness to buy, the brand image had a positive and significant effect on willingness to buy, and product country image had a significant positive effect on brand image. Meanwhile, ethnocentrism and product country image do not affect willingness to buy. This study helps to improve our understanding of consumer behaviour regarding the purchase of foreign products.
