Abstract

This study evaluates the socio-economic and environmental impact of the Dewantara Program, a multi-stakeholder partnership among PT PLN Nusantara Power UP Tenayan, community groups, government, and academia along the Siak River, Tebing Tinggi Okura, Riau. The partnership addresses river ecosystem degradation from annual erosion of 10–20 meters, 4 hectares of critical land, and declining fisheries income alongside chronic community economic vulnerability. Using a Social Return on Investment (SROI) approach combined with qualitative case-study methods (in-depth interviews, focus group discussions, and document review), this study measured value created by three interventions: FABA-based B-Block coastal conservation, biofloc and earthworm cultivation, and community-managed ecotourism. From 2022 to 2025, the partnership generated a total present value of impact of IDR 1,261,838,199 against IDR 583,194,080 in contributed resources, yielding an SROI ratio of 2.16. Economic impact accounted for 86% of total value, with the community-led Pokdarwis tourism group capturing the largest share (84.76%). Mangrove rehabilitation success rose from 30% to 90% along 212 meters of coastline. These findings suggest that river-based community development achieves greater social value when structured as a genuine multi-stakeholder partnership rather than a single-actor intervention.

Abstract

The Tebing Tinggi Okura sub-district in Pekanbaru faces a dual burden of Siak riverbank erosion, roughly four hectares of critical land, and unmanaged palm oil solid waste, compounded by declining fishing income and weak community institutions. In response, PT PLN Nusantara Power's Unit Pembangkitan (UP) Tenayan developed the Dewantara Program, a radical social innovation that converts the company's coal combustion residue (Fly Ash and Bottom Ash/FABA) into B-Block, a mangrove-planting technology that raised rehabilitation success from approximately 30 % under conventional bamboo/timber methods to about 90 %. The program integrates three pillars, community participation, FABA utilization, and the company's core competence, and is delivered through three interconnected sub-programs: the Taman Bunga Impian Okura ecotourism park, biofloc tilapia farming, and earthworm cultivation, involving the Tourism Awareness Group (Pokdarwis), the Siak River Care Youth Group (KPPS), and the Setukul Indah Jaya Fishermen Group (SIJ). This article documents the empowerment stages, from initiation and capacity building to physical-ecological construction and institutional mentoring and analyzes the outcomes using a Sustainability Compass framework covering social, economic, environmental, and wellbeing dimensions. Findings show that critical land has been restored into productive green space, new household income streams have emerged, and local institutions have been strengthened, demonstrating how industrial by-products can be redirected into community-based ecological and economic value.
