Economics 1.B. ABC Company is one of the largest e-commerce companies in Indonesia. One of the advantages of this company is the wide range of product categories offered on its website, ranging from daily necessities, fashion products, skincare and personal care. The marketing manager of ABC company realized that currently, the promotional costs incurred by the company were too large. There needs to be efficiency in this cost so that the company's margins are maintained. For this reason, the marketing manager intends to reduce promotional activities for segments that are considered less profitable by the company. For that, the company must first know the segments that are consumers of the company. For this reason, research was conducted to group consumers into segments to make it easier for companies to understand and analyze. This grouping is done based on several criteria, namely age, income and spending. Based on the research that has been done, the following results were obtained: Segment 1 consists of consumers with an average age of 32 years, has a relatively high annual income compared to other segments and the highest spending score compared to other segments Segment 2 consists of consumers with an average age of 41 years, has a relatively high annual income compared to other segments but the lowest spending score compared to other segments . Segment 3 consists of young consumers, with an average age of 25 years, having the lowest annual income compared to other segments, but the 2nd highest spending score among all segments . Segment 4 is the segment with the largest number of members, has an average age of 28, medium annual income and also medium spending score From the results of this study, ABC company decided to focus on segments 1 and 3 because they are considered the most potential when compared to the other 2 segments. Therefore, in the future, the promotional budget will be allocated more for segments 1 and 3, while the promotional budget for segments 2 and 4 will be reduced. I.
