Abstract

The development of small business is increasing with the presence of global competition. The current industrial ecology demands a continuous evaluation process to be able to survive and strive to improve quality products. Weeka Wedang Uwuh continuously improves its business system by paying attention to suppliers of raw materials. Supplier evaluation is carried out to guarantee sustainable quality and performance. Sustainable performance evaluation can produce good judgment if it is supported by a performance appraisal instrument. Supplier performance assessment will be useful to build a good and sustainable relationship between entrepreneurs and suppliers. The design of supplier performance evaluation is carried out using the QCDFR model approach namely, Quality, Cost, Delivery, Flexibility and Responsibility. The sub-criteria study that forms the QCDFR model is carried out using the interview method. QCDFR and Sub Criteria hereinafter referred to as KPI (Key Performance Indicator). KPI is an indicator of ongoing evaluation of the relationship between suppliers and entrepreneurs. The assessment of suppliers from entrepreneurs is carried out using the AHP approach which is able to show the weight of the entrepreneur's assessment of the ability of suppliers. The results of the Weeka Wedang Uwuh supplier performance evaluation model design results in a formulation to measure KPIs with criteria: quality of raw materials (size and condition of raw materials), ease of service (payment tolerance and information on availability and price changes, experience (average transaction value and average) average number of transactions), speed of response (changes in the amount and change in time and price of raw materials). Evaluation of the supplier's weight assessment for raw materials of ginger, sugar and sapphire resulted in the values of Mr. Sarno 0.501, Sugeng 0.709 and Mbak Wang 0.690. KPI measurement reinforces the results of the evaluation of weight assessment using AHP.

Abstract

Suppliers are sources providing the first material where the chain of goods distribution will start. Nowadays, the method of making decisions on the supply of bamboo raw materials for UKM Karya Manunggal is by conventional (intuition), so that it is often inappropriate in selecting the suppliers. Along with the increasingly fierce level of competition in the field of bamboo furniture, Karya Manunggal needs to review the strategy in the competition and to evaluate the ability of suppliers who are the main raw material providers. Therefore, the authors conducted a study that can be used by companies to measure the weight of each supplier by applying the Analytic Network Process (ANP) method. The Analytic Network Process (ANP) method was used to determine the ratio of the inner dependence and the outer dependence and the feedback. There were 7 criteria which were divided into 14 sub criteria and 6 alternatives used in this study. The final result was Arista Bambu with a weight of 0.2327, followed by Pak Wagiyo with 0.2106, Pak Paimin with 0.1737, Pak Gianto with 0.1506, Pak Tofa with 0.1217, and Pak Manto with 0.1107 .
