Abstract

The purpose of this study was to determine the effectiveness of Spirulina platensis for remediation of vannamei shrimp culture waste. The method used in this study was a Non-Factoral Completely Randomized Design (CRD) with 4 treatments and 3 replications, namely (A) Control; (B) 50% waste (1500 ml waste + 1500 ml water) + technical fertilizer + Spirulina inoculant; (C) 75% waste (2,250 ml of waste + 750 ml of water) technical fertilizer + Spirulina inoculant; (D) 100% waste + technical fertilizer + Spirulina inoculant. Data analysis used ANOVA with 95% confidence level. The results showed that the use of Spirulina platensis as a remediation agent for vaname shrimp culture had a significant effect on reducing levels of waste ammonia, phosphate, nitrate, and density of Spirulina platensis (Fcount > Ftable 0.05).Keywords: Bioremediator; Innoculant; Vanname shrimp; Waste water

Abstract

Green investment has become a strategic instrument for promoting sustainable economic growth in the era of climate change, environmental degradation, and global sustainability commitments. This article examines the role of green investment in supporting sustainable economic growth through a comparative study of Singapore and Indonesia. Singapore represents a highly developed economy with strong financial governance, advanced sustainable finance regulation, and a clear national agenda through the Singapore Green Plan 2030. Indonesia, on the other hand, represents a large emerging economy with abundant natural resources, high development needs, and growing sustainable finance policies, including the Taxonomy for Indonesian Sustainable Finance. Using a qualitative-comparative approach based on policy analysis and literature review, this study explores how both countries mobilize green investment to support low-carbon transition, renewable energy, green finance, and sustainable development. The findings show that Singapore’s strength lies in its role as a regional green finance hub, regulatory readiness, and institutional capacity, while Indonesia’s strength lies in its large-scale green project potential, renewable energy resources, and domestic development demand. However, both countries face different challenges. Singapore faces limitations in land, energy resources, and domestic project scale, while Indonesia faces challenges related to financing gaps, regulatory coordination, fossil fuel dependence, and implementation capacity. This study concludes that green investment can accelerate sustainable economic growth when supported by strong governance, clear taxonomy, policy consistency, private-sector participation, and regional cooperation.
