EcoCARDS: Physical Characteristic Analysis of Plantable Paper and the Feasibility of a Web-Based Educational Instrument

Research Abstract

The massive accumulation of canang flower waste from Balinese daily rituals and the increasing volume of paper waste necessitate sustainable upcycling solutions. This study aims to: (1) characterize the physical and physico-chemical properties of EcoCARDS, an innovative plantable paper, and (2) to evaluate the feasibility level of the "Web-Based Educational Instrument" as a digital learning instrument for EcoCARDS based on the assessment of visual design, usability, and content quality. An experimental research design was combined with a Research and Development approach. The physical characterization phase assessed parameters including pH, grammage, and seed germination rate. The digital phase involved the development of an interactive website, followed by a feasibility assessment using a Likert-scale questionnaire distributed among respondents to measure visual design, usability, and content quality. Based on the results of the study, it can be concluded that (1) the physical and physico-chemical characteristics of EcoCARDS are as follows: pH = 7; moisture content = 14.67%; grammage = 12.67 g/m²; thickness = 0.023 mm; water absorption time = 10.63 seconds; and the presence of lignin indicated by a brown coloration when treated with iodine, with cayenne pepper seeds embedded in the cards successfully germinating by day 7 to confirm planting functionality. (2) the web-based educational instrument was rated as Feasible. These findings suggest that the integration of EcoCARDS with a digital platform effectively transforms ritual waste into a scientifically validated product while providing an accessible medium for environmental education.
