Abstract

This research aims to analyze the performance of the shallot supply chain in Samosir Regency. Place and Time of Research This research was conducted in Samosir Regency, North Sumatra Province. Data Collection and Analysis Analysis of the Condition of the Shallot Supply Chain The condition of the shallot supply chain is discussed descriptively following the FSCN (Food Supply Chain Network) discussion framework developed by Van der Vorst. The research results show that shallot supply chain activities in Samosir Regency are based on a food supply chain networking model where fluctuating prices and weather are the main inhibiting factors in supply chain activities starting from product availability to delivery. Measuring the performance of the shallot supply chain using the Supply Chain Operations Reference (SCOR) method has not shown optimal results on all indicators such as delivery performance, standard compliance and conformity with standards. Judging from the profit shares of producers, collectors and retailers, they differ from each other, this reflects the unequal profits of each trading system so that the trading system in this area is not yet efficient. In general, the shallot trading system in this village is not yet efficient. It is a good idea for farmers themselves to sort and sort small, medium and large shallots. So that the selling price can also increase and be more profitable.

Abstract

Supply chain risk management (SCRM) has become a critical strategic imperative in the post-pandemic and geopolitically turbulent era, yet systematic comparative evidence across ASEAN and European manufacturing contexts remains scarce. This paper employs a Structured Literature Analysis (SLA) of 50 peer-reviewed studies published between 2008 and 2025 to comparatively examine SCRM frameworks, risk typologies, mitigation strategies, digital transformation trajectories, and sustainability integration across the two regions. To the best of the authors’ knowledge, this is the first study to apply a thematic cross-regional comparison framework specifically to ASEAN European manufacturing SCRM divergence, addressing a gap left by predominantly single-region studies. Key findings reveal that both regions face structurally similar risk categories geopolitical disruption, demand volatility, natural disasters, and supplier concentration but adopt divergent strategic responses: ASEAN systems prioritize network-based resilience and regional value chain integration, while European manufacturers increasingly pursue strategic autonomy and regulatory-driven resilience. Digital transformation and sustainability serve as important resilience enablers across both contexts, though their implementation depth and regulatory drivers differ substantially. Theoretical contributions include a Cross-Regional SCRM Divergence Model (CR-SCRM) and a risk-resilience-sustainability integration framework with implications for policymakers and operations managers. Keywords: Supply Chain Risk Management; ASEAN; European Manufacturing; Resilience; Digital Transformation; Sustainability; Geopolitical Risk; Comparative Analysis

Abstract

This study aims to determine the level of pelagic fish diversity in the waters of the East Coast of North Sumatra and describe the condition of the existing fish community as the basis for sustainable fisheries management. The research was carried out in three main locations, namely Belawan, Tanjung Balai, and Kuala Tanjung, during the period from March to May 2025. The research method uses field surveys with purposive sampling techniques through landing fishermen's catches, species identification, and diversity analysis with Shannon-Wiener indices, uniformity, and dominance. The results of the study showed that eight types of pelagic fish were found, with mackerel (Rastrelliger spp.) and tembang fish (Sardinella fimbriata) as the dominant species. The diversity index value (H' = 1.91) indicated moderate diversity, with high uniformity (E = 0.92) and low dominance (C = 0.14). This indicates that the pelagic fish community in the region is relatively stable and is not dominated by one particular type of fish. Differences between locations show the influence of environmental conditions and human activities. These results reinforce the importance of ecological-based fisheries resource management to maintain the sustainability and balance of marine ecosystems on the East Coast of North Sumatra.
