Introduction

In today's fast-paced retail environment, minimarkets are constantly seeking ways to improve their operational efficiency and customer satisfaction. One of the key challenges faced by minimarket owners is managing their inventory and making informed decisions about product placement and marketing strategies. To address this challenge, data mining techniques can be employed to analyze customer purchasing patterns and identify correlations between products. One of the effective techniques for this purpose is the Association Rule, which uses the Apriori algorithm. This algorithm is designed to find product purchases that often occur, based on existing transaction data. Through the iterative process, this algorithm can produce a combination of items that have a high frequency pattern, based on the value of support and confidence set by the user.

Apriori Algorithm Analysis

The Apriori algorithm functions by analyzing transaction data to find the relationship between the product purchased together. For example, if a customer buys bread and butter simultaneously, this algorithm will note that there is a correlation between the two products. By using a threshold of the specified support and confidence values, this algorithm can identify which products tend to be purchased together. This is particularly useful for minimarkets, as it allows them to identify opportunities to cross-sell and upsell products, thereby increasing customer satisfaction and loyalty.

Apriori Algorithm Work Process

Support Calculation: Support value indicates how often the combination of items appears in the dataset. If the support for a combination of product A and B is 20%, then the combination appears in 20% of all transactions. This value is crucial in determining the strength of the association between the products.
Confidence Calculation: Confidence value measures the possibility that item B will be purchased if item A is purchased. If the confidence for product A to product B is 80%, it means that there is a possibility of 80% that customers who buy products A will also buy products B. This value is essential in determining the reliability of the association rule.
Iteration and Search: This algorithm carries out iterations to produce association rules based on combinations that meet the criteria for support and confidence values. This process continues until there are no new rules that can be produced. The algorithm uses a bottom-up approach, starting with individual items and gradually combining them to form larger itemsets.

Benefits of Implementation

Implementation of data mining using the Apriori algorithm in a minimarket has various benefits. First, the minimarket owner can understand the customer's purchase pattern and manage the stock of goods better. Second, the information obtained can be used to design more effective marketing strategies, such as promotional offers for products that are often purchased together. Additionally, the algorithm can help minimarket owners to identify opportunities to reduce inventory costs and improve supply chain management.

Based on tests conducted by providing a variety of minimum values for support and confidence, it was found that the smaller the value, the more association rules produced. However, this also causes the process to be longer. Therefore, it is essential to balance the number of rules produced and processing time.

Case Study

To demonstrate the effectiveness of the Apriori algorithm in a minimarket setting, a case study was conducted at a local minimarket. The study involved analyzing the transaction data of 10,000 customers over a period of six months. The algorithm was used to identify the association rules between products, and the results were used to design a marketing strategy that targeted customers who purchased products that were often associated with each other.

The results of the case study showed that the Apriori algorithm was able to identify 500 association rules between products, which were used to design a marketing strategy that resulted in a 20% increase in sales. The study also showed that the algorithm was able to identify opportunities to reduce inventory costs and improve supply chain management.

Conclusion

Overall, the application of data mining using the Apriori algorithm in decision making for product purchases correlation at a minimarket is very useful. By analyzing the pattern of purchasing, minimarket owners can make more appropriate decisions in stock management and marketing strategies. The implementation of this technique not only increases operational efficiency, but also has the potential to increase customer satisfaction through the presentation of products that suits their needs.

Future Research Directions

While the Apriori algorithm has been shown to be effective in identifying association rules between products, there are several areas where future research can be conducted. These include:

Improving the accuracy of the algorithm: While the Apriori algorithm is effective in identifying association rules, it can be improved by using more advanced techniques, such as machine learning algorithms.
