DEVELOPMENT OF A WEB-BASED INFORMATION SYSTEM FOR DISTRIBUTING USED COOKING OIL USING THE WATERFALL METHOD

Abstract

Improper disposal of used cooking oil remains a serious environmental problem in Indonesia, including in Sidoarjo, where high waste generation and low public awareness contribute to water and soil pollution. In response to this issue, this study develops a website-based information system designed to support the management and distribution of used cooking oil more effectively and systematically. The system was developed using the Waterfall method, which includes stages of requirements to ensure a structured development process. Through observations, both functional and non-functional requirements were identified, resulting in features such as user registration, input of cooking oil collection data, tracking of collection history, incentive calculation, data visualization, and administrative reporting. Black-box testing confirmed that all major system functions operated according to the defined requirements. The resulting information system is expected to improve transparency, coordination, and efficiency in used cooking oil management, encourage community participation through a digital platform, and provide a practical technological solution to reduce environmental problems caused by improper cooking oil disposal.
