Abstract
Seaweed processing commonly generates biomass waste either used as a low-value product or discarded. However, the waste still contains nutrients that can be recovered to generate valuable products, such as fertilizer. This study aimed to valorize seaweed Gracilaria sp. biomass waste into liquid organic fertilizer to support sustainable and eco-friendly production. Gracilaria sp. biomass waste from Karawang Regency (Indonesia) was composted, and two liquid organic fertilizer doses (0.5 and 1.0% v/v of compost liquid) were formulated. The fertilizer variants were then applied to Capsicum frutescens L. plants and the plants' growth parameters (plant height, relative growth rate, number of leaves, and dry weight) were evaluated. The fertilizer's physicochemical properties (organic-C, total N, P, K, and pH) were also analyzed. The assessment results were then compared to the control and commercial organic fertilizer. The present study showed that both seaweed waste-based fertilizer variants generated higher C. frutescens L. plant growth parameters than the control, with comparable outcomes to the commercial one. This result could be achieved, although the fertilizer's organic-C, total N, P, and K content were below the national technical standard. These findings demonstrate that seaweed biomass waste is prospective for organic fertilizer development.
