The production process of cassava chips begins with the preparation of cassava raw materials and then the process of separating the skin from cassava. The process of cutting cassava into a certain size uses a special machine that is operated manually. The process of frying cassava using a large pan and the process of packaging into plastic are the last step of production. Planning the production of cassava chips starts with preparing the needs of raw materials for production for 3 days in a week ordered from 3 different suppliers to prepare production needs, the quantity needed in purchasing from suppliers includes 120 kg of cassava, 9 kg of red chili, 1 kg of garlic, 3 kg of lime, 27 kg of cooking oil, 9 kg of sugar and 0.25 kg of salt. The initial supply of cassava raw materials provided is 120 kg and at the end of the week the production inventory needs are 80 kg left from the use of 40 kg at the end of the week for the next production.

Abstract

The selection and assessment process of suppliers carried out by Private Airline Holding Company uses subjective assessment. It is not so transparent from the department's head with five criteria of suppliers and just enough sub-criteria. This matter inflicted a few problems, such as the goods received from suppliers not being by the amount ordered, the established quality standards, delays in estimated time delivered and received, and defects often found in the goods. Analytical Hierarchy Process (AHP) is a method that helps solve complex problems by structuring a hierarchy of criteria, stakeholders, and outcomes and by considering many things to develop values or priorities. This research aims to determine the priority criteria and sub-criteria of pilot and flight attendant uniform suppliers and the priority order of the best suppliers, Private Airline Holding Company. This research uses Expert Choice V.11 software to implement the AHP method. The overall evaluation obtained shows that five criteria and thirteen sub-criteria were used. The best supplier based on data processing is Supplier 1, with a value of 0.213.
