Abstract

The shift of Corporate Social Responsibility (CSR) from a voluntary commitment to a business strategy and regulatory obligation has increased the need for measurable assessments of the social and environmental impacts of corporate sustainability initiatives. This study evaluates the effectiveness and the social, economic, and environmental value created by the KIJANGKU (Konservasi Hijau Selamatkan Lingkunganku) Social Innovation Program, implemented by PT Toyota Motor Manufacturing Indonesia (TMMIN) at Karawang Plants 1–2 during 2023–2025. Using the Social Return on Investment (SROI) approach, the study assesses the value generated relative to the program’s social investment. A total investment of IDR 381,000,000 (present value: IDR 399,237,600) produced benefits with a present value of IDR 524,762,076, yielding an SROI ratio of 1.31. Each IDR 1 invested thus generated approximately IDR 1.31 in social, economic, and environmental value. The findings indicate that KIJANGKU benefited local communities while supporting environmental conservation and sustainability. The study highlights the applicability of SROI for evaluating the broader impacts of corporate social innovation programs and their contribution to the Sustainable Development Goals (SDGs), including SDG 1 (No Poverty), SDG 8 (Decent Work and Economic Growth), SDG 13 (Climate Action), and SDG 17 (Partnerships for the Goals).

Abstract

Management of biodiversity in industrial areas requires a strategic approach to balance manufacturing activities with ecosystem conservation. This study aims to examine the effectiveness of applying the Focus-Diversify-Maintain (FDM) framework in optimizing biodiversity management and carbon storage at PT Toyota Motor Manufacturing Indonesia (TMMIN) Karawang Plant 3. Flora data collection was conducted via census in 8 built-up land blocks and sampling in undeveloped land. Avifauna data were gathered using a combination of point count, vantage point, species list methods, and drone-based aerial monitoring. Calculations of above-ground carbon stocks were performed based on biomass formulas and standard carbon conversion equations. The results identified 24 plant species from 13 families, totaling 1,302 tree and non-tree individuals in built-up areas, alongside 44 bird species from 24 families. The Shannon-Wiener diversity index ( ) for birds reached 2.227, dominated by Nycticorax nycticorax, Egretta garzetta, and Lonchura punctulata. The descriptively formulated FDM framework has the potential to guide priority avifauna conservation zoning (Focus), plan the enrichment of local food flora (Diversify), and recommend maintaining carbon sink functions (Maintain) within industrial areas.
