Pharmacies themselves have a close relationship with pharmaceutical companies and of course the Ministry of Health as a regulator related to the sale and marketing of drugs to the public. The main task of a pharmacy is to distribute drugs and provide a report data recap. At present, the problems faced in drug distribution are the uneven demand for drug distribution. Sometimes, the drug runs out or excess stock will be problematic with the accumulation of the amount of goods in the warehouse and can become expired and can be dangerous if distributed to the public. To overcome this problem, a computerized system was created. The system functions to recap the amount of goods and provides a recommendation on what items are most purchased by customers or patients. The method used is by using the Association rule Algorithm. The algorithm can display the number of relationships or relationships of the most sold products from 20% to 80% by calculating the value of support and confident. Keywords: Association rule; Information system; Pharmacies; Stock management. 1. Introduction At present, health is a very important matter where many activities are carried out outside the room starting from work, activities with the family and others. Very busy activities sometimes make peo- ple forget about their health. This causes the source of the disease to always be there. When this disease arises, it certainly requires medication to cure it. With the need for these drugs, the communi- ty will quickly find the nearest pharmacy and look for the drug. The most important thing is the availability of these drugs at the pharmacy. The speed of getting a drug, of course, is very important for pa- tients. Delays in the search for drugs can aggravate the disease suffered and can even cause death. Because of that, accuracy is needed in determining which pharmacy provides the medicine needed. Pharmacies also have a dual role other than as an extension of the government for drug distribution. Another function is to provide services and counselling to the community related to the im- portance of health. To visit a pharmacy, customers or patients can come directly and even online. With this online visit, the patient can check whether the reference drug is in the pharmacy or not. The reliability of this information system can be more precise and quickly respond to all patient needs. Trimitra Herbal Pharmacy, as one of the concepts of modern pharmacies, tries to develop a new concept which will create an online sales and availability infor- mation system. Patients or customers can directly see the list of drugs available at the pharmacy and provide suggestions and rec- ommendations for the next drug. The information system is not only used by patients but by pharmacy owners where pharmacy management systems can be helped by the results of sales data analysis. From the results of the analysis, it can be seen the pattern of drug purchases made by patients. The results of this analysis serve as a product promotion strategy and stock submission. The process is carried out by computerized techniques with the associ- ation method wherein the transaction database will find important information data in the previous transaction that cannot be done manually. 2. Literature Review Pharmacies are a place to provide debriefing about health which serves to hold, store and sell drugs. The important thing from pharmacies is being able to provide information to the public about the functions and types of drugs. Another strategic function of the pharmacy is a media from the government and the private sector working in the health sector that processes the buying and selling of drugs or other medical devices. The sales transaction is large and in a fairly long period of time. To analyze the sales data, the concept of data mining is needed which functions to find im- portant information on the data [1]. A manager is able to determine the buying pattern in a sales trans- action by analyzing sales data. From the purchase pattern, it can be seen which drugs or medical devices are most often purchased by consumers. This will make it easier to determine which drug or medical device will be placed on the front of the sales rack and its adjacent position. The strategy or system by placing goods or products that are often sold on shelves with close placement is usually called "market basket analysis" [2]. Competition between companies in business today has utilized information technology where customers and buyers can transact, market their products directly without having to meet. The func- tion of the information system is to produce a database of recorded sales transactions in previous years. In the database there is infor- mation that is very useful to see the most number of items. The
