An adequate sustainable production inventory model is expected to represent complex real-life cases involving fuel, emissions, and electricity costs as well as multi-materials, quality degradation, and probabilistic demand. Therefore, this study was conducted to develop this kind of model to determine the number of raw material shipments (), production cycle time (), and the number of finished goods delivered (n) to maximize the Expected Total Profit (ETP). The proposed model is based on a bibliometric literature analysis of the sustainable production-inventory problem which is visualized using the VOSviewer. Moreover, a sophisticated Harris-Hawks Optimization (HHO) algorithm was proposed to solve the problems identified in the sustainable production inventory model optimization. It is also important to note that three numerical cases were provided to evaluate the performance of the algorithm. The findings showed that the suggested HHO method outperforms the Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) in maximizing ETP and this means it is better for ETP optimization. It was also discovered from the sensitivity analysis that an increase in the rate of quality degradation (k) led to a reduction in both the ETP and T.

Bioeconomics is an emerging concept and has not been given a generally accepted definition. Bioeconomic strategy tries to consider every aspect of this emerging concept from different perspectives depending on the country, region, or organization that publishes it. Therefore, each strategy has its advantages depending on the economic, geomorphological, social, environmental, and technological conditions of each country. In this review, attempts are made to address key trend areas of bioeconomic strategies through a systematic literature review. PRISMA analysis is used to review the literature on key trend areas of bioeconomic strategies. Review articles address this topic in two major scientific literature databases, namely Scopus and AgEcon. Using a repeatable search process to identify relevant studies in the literature, only 68 publications that met the eligibility criteria were included in the review. The results showed that the movement of the main trends of the Bioeconomic Strategy in agro-industry 2013-2022 was observed as well as the economic and technological development of each country to show its superiority. The transition to a successful bioeconomy model requires the participation of the whole society because a sustainable society as a whole requires sustainable and environmentally responsible solutions. The study concludes that management with global coordination and training for stakeholders is necessary for the successful implementation of bioeconomic strategies in agro-industry.

The coffee agroindustry in Indonesia, particularly in Malang Raya, has undergone expansion through the increased development of coffee processing industries, including waste and emissions. Various factors, including farming practices, land use, waste management, and the utilization of by-products influence the emission levels in the supply chain. A value chain analysis in supply chain management is essential to support sustainable coffee agroindustry. The complexity of the coffee value chain involves multiple stakeholders, including input providers, producers, traders, cooperatives, and exporters, emphasizing the intricate nature of the coffee chain and the need for coordinated efforts to ensure quality and sustainability. This research aims to identify emission sources in the supply chain and determine the economic impact of coffee production at the farmer level. The value chain operations reference is the method used for measuring the value chain. The calculation results indicate that the carbon emission footprint in the supply chain activities at the farmer level amounts to 22,734 kg CO2 with a unit cost of 0.75 €/kg. These values suggest that activities in the coffee value chain at the farmer level are still not environmentally friendly (intolerable region). Suggested approaches for enhancing the value chain for coffee farmers in Karangploso encompass the installation of a smart GPS system in vehicles for route optimization and fuel efficiency, and using organic fertilizers instead of chemical fertilizers to prevent water pollution, along with the adoption of an organic farming system to enhance the economic value of the harvest. The findings of this study are expected to be a reference for research on the value chain in coffee supply chain activities, and contribute to the enrichment of information related to the VCOR model

The coffee supply chain involves high production volumes, complex multi actor interactions, and increasing sustainability requirements, yet remains highly vulnerable to risks dimension. This study aims to develop and evaluate a decision-support framework that improves the accuracy and consistency of sustainability risk classification in the coffee supply chain. The proposed framework integrates failure mode and effect analysis (FMEA) with a supervised artificial neural network (ANN) using backpropagation (BP) to enable data-driven and adaptive risk assessment. Empirical data was collected from 55 respondents, resulting in the identification of 35 supply chain risk factors. These data were used to train and validate an ANN-based classification model implemented in a Python environment, with standard preprocessing and stratified data partitioning to ensure robustness. The ANN classified risks into five categories using supervised learning. The results demonstrate strong predictive performance, achieving overall accuracy of 98.97%, with precision, recall, and F1-scores exceeding 96.8% across all risk classes. Confusion matrix analysis confirms reliable generalization and minimal misclassification. The findings indicate that integrating FMEA with ANN-BP significantly enhances risk classification compared to conventional qualitative approaches. The proposed framework provides a scalable and reliable decision-support tool for dynamic risk scoring, supporting enhancement of sustainable practices in agro-industrial coffee supply chains.

Indonesian coffee products face increasingly intense competition in both domestic and international markets, making sustainable branding a strategic requirement for agropolitan regions with strong local identities. This study analyzes the priority factors that influence purchasing decisions for Kapiten Coffee in Pasuruan Regency and formulates a sustainable brand image strategy based on local identity, consumer value, and digital market visibility. The research employed a mixed-method design by combining field observation, consumer-oriented survey indicators, semi-structured stakeholder input, and the Analytical Hierarchy Process (AHP). The criteria examined were product quality, promotion, price, and brand image, while the sub-criteria reflected performance, features, conformity, durability, reliability, service, aesthetics, perceived quality, advertising, social media exposure, discounts, sampling, souvenirs, price affordability, price-quality fairness, price-benefit fairness, competitive price, brand association, consumer experience, perceived product quality, uniqueness, brand personality, and lifestyle congruence. The AHP results show that promotion was the strongest priority criterion (0.2978; 30%), followed by product quality (0.27577; 28%), price (0.2158; 22%), and brand image (0.2107; 21%). At the global indicator level, advertising and promotional visibility achieved the highest weighted score (0.132), followed by product performance (0.088), brand association (0.082), social media exposure (0.073), and price-quality fairness (0.064). These findings indicate that Kapiten Coffee requires an integrated strategy that uses promotion as an entry point for brand awareness while strengthening product consistency, locally rooted storytelling, experiential marketing, and sustainable value communication. The study contributes to agropolitan coffee marketing by demonstrating how AHP-based prioritization can transform fragmented promotional activities into a structured sustainable branding roadmap for local coffee competitiveness.

Indonesia’s cocoa sector faces challenges in greenhouse gas emissions and smallholder income volatility. This study develops a system dynamics model to simulate the interrelationship between carbon emissions and economic performance across the cocoa value chain, identify leverage points, and evaluate alternative policy scenarios. The model integrates environmental and economic variables into dynamic feedback structures, enabling scenario-based assessment of intervention strategies. Five scenarios were simulated: composting cocoa waste increased farmer income by 2% and reduced farm-level emissions from 0.43 to 0.303 kg CO₂-eq/kg (29.79% total reduction); biogas conversion raised income by 13.56% and reduced emissions by 11%; converting cocoa waste into animal feed slightly increased income by 0.23% while cutting emissions by 58.6%; combining composting with improved transport efficiency reduced emissions by 14%; and integrating composting, logistics optimization, and government-supported input subsidies yielded the highest performance, with a 13.50% income increase and a 70% emission reduction. These results demonstrate that integrated, system-based interventions can enhance both economic resilience and environmental sustainability. The system dynamics model provides policymakers and supply chain actors with actionable insights for designing effective, climate-aligned strategies in Indonesia’s cocoa industry.
