Abstract:
This study aims to find patterns of drug combinations that are often bought together. One
way to solve this problem is the Association rule method using the CT-Pro algorithm.
This algorithm is a market basket analysis algorithm which is one of the techniques of
data mining to study the habitual behavior of consumers in buying products
simultaneously. The research method applied consists of data collection. The data used
are drug purchase transaction data at the University of Riau Hospital Pharmacy, then
system analysis, system design, system implementation, and finally system testing. Based
on the results of this study, a combination pattern of purchasing drugs that are sold at
the same time is obtained as a reference in increasing drug stocks.
