Abstract

PT. Nutrimax is a distributor company that is engaged in selling supplements in the Range. Sales of supplements have increased sales every year. However, PT. Nutrimax has problems in controlling inventory of goods that cannot be predicted properly. That was caused by the Head of the Warehouse of PT. Nurimax at the end of each month only manually counting the number of supplements left on the supplement rack and warehouse, and then reporting to the leadership. To avoid and minimize future loss of supplement sales, PT. Nutrimax needs to have a sales forecasting activity using the Least Square method, using the PHP programming language and MySQL database. Least Square method is a method used to estimate or forecast in the future. In predicting the supply of supplements, the data used from January-May 2020 so that later predictions can be obtained in the form of a lot of supplement stock that must be provided by PT. Lutrimax. The final results of this study are expected to help the process of calculating future supplement forecasting easily, minimizing errors, and can produce accurate and fast forecasts.
