English
This study evaluates the environmental performance of B100 biodiesel from kemiri sunan using life cycle assessment (LCA). Integrating solar PV reduces emissions by 56% and shortens the carbon payback period from 11 to 6 years. The biodiesel shows lower carbon emissions than fossil diesel and comparable to palm oil biodiesel, highlighting its potential as a sustainable non-edible biofuel under the Nature-Based Solutions framework.

日本のGX文脈において
日本では、バイオ燃料の持続可能性基準やLCA手法が注目されており、本研究成果は非食用原料や再生可能エネルギー統合の効果を定量的に示す点で、国内のバイオ燃料政策や企業のサプライチェーン排出削減に示唆を与える。ただし、インドネシアのケーススタディであり、日本への適用には地域特性の考慮が必要。
In the global GX context
This study contributes to global biofuel sustainability assessment by integrating carbon payback period and renewable energy integration into LCA. It provides empirical evidence for the potential of non-edible feedstocks on marginal lands, relevant to international frameworks like ISSB and CSRD that require robust carbon accounting. The findings support transition finance decisions by quantifying emission reduction and payback timelines.

📄 Abstract（原文）
Background: Rising greenhouse gas emissions have increased the need for sustainable biofuels. Biodiesel from the non-edible feedstock Reutealis trisperma (kemiri sunan) offers a low-carbon alternative compatible with marginal lands under the Nature-Based Solutions (NbS) framework. Objective: This study evaluates the environmental performance of B100 biodiesel production from kemiri sunan and quantifies the effects of renewable energy integration on emission reduction, energy efficiency, and carbon payback. Methods: A Life Cycle Assessment (LCA) using a cradle-to-gate system boundary (functional unit: 1 liter of B100 biodiesel) was conducted using OpenLCA with the Ecoinvent 3.11 database, ReCiPe 2016 Midpoint (H), IPCC 2013, and Cumulative Energy Demand methods. The assessment covered the entire production chain from cultivation to bio-additive blending. Results: The carbon emissions of kemiri sunan B100 biodiesel were 2.04 kg CO₂-eq per liter, which were significantly lower than those of fossil diesel (3,400 kg CO₂-eq/ton) and comparable to palm oil biodiesel (1,659 kg CO₂-eq/ton). Transitioning to solar photovoltaic (PV) electricity reduced emissions by 56% (from 2.02 to 0.74 kg CO₂-eq). Energy balance indicators, including Net Energy Gain (NEG), Net Energy Ratio (NER), and Specific Energy Consumption (SEC), confirmed a positive energy output-to-input ratio. The Carbon Payback Period (CPP) was estimated at 11 years when using PLN electricity and was shortened to 6 years with solar PV integration. Conclusion: Kemiri sunan B100 biodiesel demonstrates strong potential as a sustainable, non-edible bioenergy source that supports low-carbon energy transitions. The integration of renewable energy, optimized cultivation management, and the utilization of degraded lands collectively enhance its environmental performance and strengthen the effectiveness of NbS implementation.
