Performance Measurement of Potato Supply Chain in North Sumatra Province

Abstract

This study aims to measure and analyse the performance of potato supply chain in North Sumatra Province. Data were collected from 150 respondents, namely, farmers, traders, distributors, and retailers through a questionnaire survey. The results showed that the average order cycle time was seven days, with a logistics cost of IDR 1,500.00 per kilogram. The product loss rate reached 10%, indicating that there were problems in handling and storage during distribution. Product quality was considered quite good with an average score of 3.8, while customer satisfaction was at a score of 3.7. Statistical analysis showed that logistics costs and product loss rates were negatively related to customers’ satisfaction, while product quality had a positive relationship. SWOT analysis identified that infrastructure improvements, training, and implementation of information technology were needed to improve supply chain performance. Key recommendations are to improve road infrastructure, training for farmers, and product diversification. By implementing these recommendations, it is hoped that the efficiency and effectiveness of the potato supply chain in North Sumatra can be improved, which will ultimately improve farmers’ welfare and product competitiveness in the market.
