Development and Feasibility Study of Plant Pots Using Earthworm Compost for Sustainable Community Promotion

Abstract

This study aimed to: (1) develop a production process for biodegradable planting pots made from vermicompost combined with organic materials, including coconut coir and soil; (2) evaluate the physical, chemical, and preliminary functional properties of the developed vermicompost-based pots; and (3) examine consumer acceptance of the product as an alternative to plastic pots to support community sustainability. A mixed-methods research design was employed. The optimal formulation consisted of 80 g of vermicompost, 100 g of rice husk ash, 100 g of coconut coir, 100 g of standard soil, and 200 g of cassava starch as a binding agent. Quantitative analyses included chemical property testing (pH, moisture content, and electrical conductivity: EC) and physical property testing (weight loss after drying and mechanical strength using a Universal Testing Machine). Seedling growth performance was also evaluated using Chinese kale over a seven-day period. Consumer acceptance data were collected from 42 participants and analyzed using descriptive statistics. The results indicated that the vermicompost-based planting pots had chemical properties suitable for plant growth (pH = 7.43, EC = 227 ppm), good moisture retention, and adequate mechanical strength for practical use. Seedling growth was comparable to the control treatment. Overall product acceptance was rated as acceptable, with environmental conservation receiving the highest mean score (M = 4.55, SD = 0.68). These findings reflect positive perceptions of biodegradability and the potential to reduce plastic use while promoting sustainable community resource utilization.
