Abstract

There is a lack of research that identifies the driver factors of food waste along the Supply Chain in cities in Indonesian, not only in households but also supermarkets and restaurants. This study aims to identify the driving factors of food waste in cities in Indonesian, especially the cities of Surabaya and Sidoarjo.  Based on the SIPOC framework (Supplier, Input, Process, Output, and Customer), literature review, and interviews using the Delphi method with 5 experts, as well as using system dynamics, the driving factors of food waste in cities in Indonesian have been determined. The significant driver factors of food waste in supermarkets and restaurants are (1) inventory planning, (2) warehousing facilities, (3) market access, (4) food standards, (5) communication and collaboration, (6) demand fluctuation, (7) processing methods and packaging designs, and (8) cold storage and other facilities. Significant driver factors of food waste in household include (1) awareness of the amount of food wasted, (2) a culture of wasting food, and (3) control over for food supply at home.
