Abstract

PT GMF Aeroasia Tbk. is the largest MRO company in Indonesia. This company has 67 plants worldwide. With the many plants that must be serviced, the complex process of repairing aircraft with spare parts that exceeds 15,000 types. Part distribution is a very big challenge and must be faced by companies where part distribution is done with multi-stage warehouses. At present the main warehouse has problems with the inefficiency of the min-max distribution system at each plant where the system aims to bond the parts that have the greatest frequency of demand to the sub-warehouse at the plant. This study discusses the improvement of Min-Max distribution with ABC Analysis NG-Model Multiple Criteria which aims to improve the efficiency of the list part number with the frequency of order transfer requests and the most optimal performance at 9 internal plants with the largest part demand activity. The proposed method is known to be able to increase min-max accommodation including, Transfer Order frequency from 23% to 40.80% and weekly delivery performance from 22% to 62.69%. In addition, this method can also reduce the amount of part number on Min-max with the results of Transfer Order accommodation and increased performance from the methods currently used.

Abstract

The advancement of science and technology in the world has brought many influences to the changes in people's behavior and habits, one of that is the technology payment system adopted as an electronic payment system. As an electronic payment instrument, OVO cooperates with one of the online-based transportation services, Grab. However, the success of a company can be seen from the quality of service in meeting the satisfaction of the community or customers. The success of the company in providing quality services can be determined by the Service Quality (Servqual) approach, that is a method used to measure service quality from the attributes of each dimension, so that a gap value will be obtained that is the difference between consumers' perceptions of services that has been received in the hope that will be received. The objective to be achieved is to propose a design in the form of alternative solutions for the priority of improving the quality of electronic money OVO services in Grab applications. Data were collected through a questionnaire using non-probability sampling techniques with a total sample of 140 respondents. The study found the main problems, namely in the dimensions of compensation, responsiveness, and Privacy/Security.
