Abstract

Today's fierce business competition requires companies to focus on the needs desired by consumers.This makes companies have to think about how to manage customer data so that it can be utilized properly for the development of marketing strategies.And Grouping (cluster) customers based on their respective characteristics can be an alternative in solving these problems.In clustering (cluster) customers there are several data mining clustering methods that can be used, one of which is the Fuzzy C-Means (FCM) method. FCM is a clustering algorithm where one object can be a member of several clusters and FCM cluster boundaries are vague. The output of FCM is a row of cluster centers and several degrees of membership for each data point. In this clustering, customers will be divided into 4 customer clusters namely Golden, Silver, Bronze, and Iron with the variables used as a reference are the final purchase date, purchase frequency and total purchase. The data used is customer transaction data for the period September - December 2015. The total data is 709 transactions from 75 customers. After the data is processed with the Fuzzy C-Means method, the final results show that the iteration ends at the 30th iteration with a change in the objective function of 9.8. The resulting customer clusters are Golden: 27, Silver: 15, and Bronze: 33 with a cluster validity of 0.596277.

Abstract

Batak Pakpak regional culture is an integral part of the richness of Indonesian culture spread across the Sumatra region. Geographically, the Pakpak Batak tribe inhabits the high hilly areas around the North Tapanuli area. Their culture encompasses various aspects, including language, customs, traditional arts, music, dance, and unique beliefs and value systems. The customs of the Pakpak Batak tribe are very strong in everyday life, with norms that regulate various aspects of social, economic and religious life. Traditional arts such as carving, weaving and stone carving are deep cultural expressions and have high value for the Pakpak people. Apart from that, traditional Batak Pakpak music and dances, such as gondang sabangunan and tortor, are important media in traditional ceremonies and cultural festivals. They are also known for their beliefs and value systems that value living in harmony with nature and the continuity of generations. This research aims to dig deeper into the cultural diversity of the Batak Pakpak in Sumatra and understand the role and cultural values in strengthening their identity. Through this analysis, it is hoped that it can provide a more comprehensive picture of this cultural richness and its implications in the context of Indonesia's cultural diversity.
