Abstract

Palm Oil Mill Effluent (POME) is a major by product of the palm oil industry, characterized by high organic content (COD 40,000 - 100,000 mg/L) and significant environmental risk if untrated. This study aims to Optimize POME conversion into biogasthrough anaerobic digestion, focusing on technical parameters (COD, pH, temperature) at PT Tunas Baru Lampung. Using a quantitative approach, data were collected over 12 months and analyzed via multiple linear regression. Results indicate COD as the dominant factor (β = 0.866, p=0.000), with optimal biogas production at pH 6.8 - 7.4 and mesophilic temperatures (30–40°C). The estimated electricity potential reached 54.62 MW/month, reducing CO₂ emissions by 21,533 tons/year. Challenges include infrastructure limitations and regulatory gaps. Recommendations include adopting advanced digester technologies, policy incentives, and further industrial-scale research. This study contributes to green manufacturing by aligning waste management with renewable energy goals and circular economy principles

Abstract

PT XYZ is a canned crab processing company that continues to experience significant operational performance gaps despite implementing the Balanced Scorecard (BSC). Several key performance indicators, such as production time, defect rate, and product innovation, consistently fall short of their targets, indicating that the current BSC functions only as a monitoring tool and does not provide a quantitative foundation for selecting the most impactful improvement strategy. This research integrates the Balanced Scorecard (BSC) with the Simple Additive Weighting (SAW) method to prioritize five alternative strategies. The SAW analysis shows that Revitalization of the Human Resource Management System emerges as the highest-priority strategy, followed by Innovation Capability Development and Human Resource Capacity Building. These top three strategies demonstrate the strongest overall impact on improving operational performance, reinforcing the central role of human resources in driving sustainable efficiency improvements. The results also reveal that human-centered strategies generate a broader cascading effect across all KPIs compared to technology-focused alternatives. This pattern highlights that improvements in employee satisfaction and training hours act as leverage points that accelerate gains in production time, defect reduction, and innovation output. Overall, the findings confirm that strengthening HR systems creates long-term operational advantages that are more consistent and scalable for PT XYZ.
