Enterprise Resource Planning (ERP) is an information system that is used to integrate all information in every business process in a company by using a shared database. Proper integration of each division can improve good communication, regular workflow, and company success. This study aims to analyze the implementation of ERP in a trading and service company. Before implementing ERP, each division, namely the warehouse division and the finance division, used a separate application. As a result, there is a difference in inventory calculation between warehouse records and finance. The study was conducted by distributing questionnaires to employees who deal directly with the ERP system in the company under study. The results of the questionnaire show that the relationship of user training and data analysis has an influence on the success of ERP implementation. After the ERP system is implemented, there are no more data miscut incidents due to work processes, spare part administration, checking of the purchase status and spare part expenditure processes in the warehouse division to be more accountable because all users use the same database for all divisions, namely the warehouse, finance, and commercial divisions. The control system of every activity in and out of goods and also better monitored, especially the spare parts that are warranty because the warehouse division has received enough information from each use of spare parts.

The aim of research is to design the model of rendement rate by considering the criteria of patchouli leaf and designing a good supplier selection model to maximize the company profit by considering the acceptance of the patchouli oil rendement rate. The selection of suppliersdiscussed is to consider the quantity of goods offered by suppliers, demand, budget and acceptance limitation of rendement rate. To overcome these limitations, it is necessary to develop a supplier selection model that takes into consideration the quantity limitation of goods offered by the supplier and the acceptance of the rendement rate by using Linear Programming (LP) method. The result of the research shows that the determination model of the rendement rate developed to determine the percentage of Rendement Rate (RR) of each raw material supplied by the supplier so that the company can know the quality of patchouli leaf based on the type of patchouli leaf. The analysis result of numerical sample calculation shows that the selected supplier is not a supplier with good patchouli leaf criteria, the analysis result of parameter changes in oil demand and budget indicate that when oil demand is increased over the benchmark data, the model output isinsensitive, but when demand is lowered below the benchmark data, the model output looks sensitive.
