Thesis Abstract
The increasing complexity and opacity of fresh produce supply chains have raised significant concerns regarding product authenticity, safety, and transparency, necessitating innovative solutions to enhance traceability and consumer confidence. This study aims to develop and evaluate a blockchain-based traceability system tailored for fresh produce supply chains, with specific objectives to analyze current traceability practices, design an integrated blockchain model, implement a prototype system, and assess its effectiveness and stakeholder acceptance. Employing a mixed-methods research design, the study integrates qualitative exploratory interviews with key supply chain stakeholders—farmers, distributors, regulatory agencies, and retailers—and quantitative surveys to gather comprehensive insights. The population consists of 300 supply chain actors across the regional fresh produce market, from which a stratified random sample of 150 participants was selected to ensure representativeness. Data collection instruments include semi-structured interview guides, structured questionnaire surveys, and system usability metrics, with validity and reliability assured through pilot testing and Cronbach’s alpha analysis. Quantitative data are analyzed using descriptive statistics, correlation analysis, and multiple regression to identify factors influencing system adoption, while qualitative data undergo thematic analysis following Braun and Clark’s framework to elucidate stakeholder perceptions and barriers. The system prototype is developed utilizing Hyperledger Fabric, incorporating smart contracts for real-time data recording and validation across multiple stakeholders, aligned with the principles of the Theory of Planned Behavior and the Technology Acceptance Model to predict user acceptance and behavioral intention. Expected findings include a significant improvement in traceability accuracy, transparency, and response time compared to existing practices, alongside increased stakeholder confidence in product provenance. The study also anticipates identifying key determinants such as perceived ease of use, trust, and perceived benefits that influence system adoption, supported by regression analyses revealing statistically significant predictors (p < 0.05). This research makes a substantive contribution to knowledge by demonstrating the feasibility and benefits of blockchain technology in agricultural supply chains, providing a replicable framework for integrating digital traceability solutions to improve food safety and supply chain transparency. The findings are expected to inform policymakers, supply chain managers, and technology developers on best practices for implementing blockchain solutions in food systems, emphasizing scalability and integration challenges. The study concludes that a blockchain-based traceability system can significantly enhance transparency, accountability, and efficiency in fresh produce supply chains, thereby reducing fraud, contamination, and inefficiencies while fostering consumer trust. Recommendations include adopting the system in collaboration with regulatory bodies, continuous stakeholder engagement, and further research into optimizing system interoperability with existing supply chain management platforms. Future studies are suggested to explore long-term impacts, cost-benefit analyses, and integration with emerging technologies such as IoT and artificial intelligence to further strengthen the robustness and scalability of blockchain-enabled traceability systems across broader agricultural sectors.
Thesis Overview
This research focuses on creating a blockchain-based system to improve the way fresh produce is traced through its supply chain. Currently, tracking the origin, handling, and movement of fresh produce is often unclear, leading to problems such as food fraud, contamination, spoilage, and difficulty in quickly responding to safety issues. The main goal of the study is to design a transparent, secure, and efficient digital platform that records every step in the supply chain using blockchain technology, which is known for its decentralized and tamper-proof nature.
The study addresses a key gap in current systems, which are often manual, fragmentated, or rely on centralized databases that can be manipulated or lost. By applying blockchain, the research aims to ensure data integrity, improve traceability, and enhance trust among stakeholders, including farmers, transporters, vendors, and consumers.
The researcher will follow a structured approach, beginning with a review of existing traceability systems and blockchain applications in food supply chains. Next, they will design a prototype blockchain system tailored for fresh produce. The study population includes key stakeholders in the supply chain from a medium-sized agricultural region, with a sample size of about 50 participants selected through purposive sampling.
Data collection will involve interviews, focus groups, and testing the prototype in real-world scenarios, alongside technical data logs. The researcher will analyze qualitative data using thematic analysis and quantitative data with descriptive statistics and correlation tests, possibly supplemented by regression analysis to identify factors influencing system adoption and effectiveness.
The anticipated outcome is a functional prototype demonstrating the potential benefits of blockchain for traceability, along with insights into practical challenges and stakeholder perceptions. The study aims to contribute to knowledge by providing a robust, scalable model that can be adopted by other regions or commodities. Ultimately, the research expects to show that blockchain can significantly improve the safety, transparency, and efficiency of fresh produce supply chains, supporting better consumer confidence and regulatory compliance.
