Introduction
In the complex environment of the global food supply chain, guaranteeing food safety, combatting fraud, and satisfying consumer needs for transparency and sustainability are crucial obstacles.Traceability and transparency have emerged as essential components for addressing these concerns and improving supply chain efficiency overall (Smith & Castonguay (2020).However, like many other sectors, the onion business struggles with transparency and traceability difficulties, which undermine customer trust and the economic sustainability of farmers and industry partners (Patel et al., 2022).
Blockchain technology, a decentralized and distributed digital ledger system, shows immense potential as a revolutionary solution to these problems.Its successful deployments in a variety of agricultural industries throughout the globe, including livestock monitoring in Argentina and tea traceability in India, have shown its potential (Rajasekaran et al., 2022;Han et al., 2023).Nevertheless, the application of blockchain technology in the Philippine onion market is underutilized.This research intends to investigate the possibilities of blockchain technology to improve traceability and transparency in the Philippines onion business.This study might enhance the lives of onion growers, increase consumer trust, and contribute to a more efficient and sustainable onion supply chain in the United States by addressing a largely untapped use of blockchain technology.
Moreover, this research has wider value as it adds to a better understanding of the function of blockchain technology in agriculture and may serve as a helpful case study for other countries wishing to deploy blockchain technology in their agricultural sectors.In accordance with the Sustainable Development Goals of the United Nations, namely Goal 2: "Zero Hunger" and Goal 12: "Responsible Consumption and Production," this research may play a crucial role in encouraging transparent and sustainable supply chains.
This project aims to pave the path for creative solutions to improve traceability, boost customer trust, and develop sustainable farming practices by solving the research gap in researching blockchain technology's potential in the Philippine onion business.

Literature Review
The literature study offers a comprehensive examination of current studies and research pertaining to the implementation of blockchain technology in the agriculture industry, notably in terms of traceability and transparency in food supply chains.This article seeks to develop a complete grasp of the topic and throw light on existing knowledge gaps regarding the implementation of blockchain technology in the Philippine onion business.

The Application of Blockchain Technology to Agricultural Supply Chains
In recent years, blockchain technology has attracted considerable interest due to its potential to change supply chains across several sectors, including agricultural.The immutable and decentralized nature of blockchain assures transparency, traceability, and increased data security.Several studies have shown successful blockchain applications in agricultural supply chains, including animal monitoring in Argentina and tea traceability in India.These case studies illustrate the disruptive influence of blockchain technology on supply chain trust and efficiency.

Traceability and Transparency in the Food Supply Chain
It is impossible to overstate the significance of traceability and transparency in the food supply chain.Verifying the origin and authenticity of food items is essential for customer confidence and food safety.According to studies, a lack of openness in agri-food supply chains may lead to fraud and food safety compromises.Adopting blockchain technology may provide a verified and immutable record of the product's journey from farm to table, hence addressing these issues (Ghosh et al., 2020).
Traceability is a reliable method for monitoring food safety in the food supply chain.In order to achieve this objective, academics and supply chain managers have implemented numerous methods such as digitization and RFID tagging to ensure traceability.However, none of these has shown to be completely effective remedies.Nevertheless, blockchain has the potential to be a genuine savior in such situations.This has been corroborated by empirical case studies conducted by prominent organizations such as IBM, Walmart, Tsinghua University, among others.IBM and Walmart collaborated on a case study in which they tracked the whole travel of a mango, from the farm to the consumer's plate, in a mere 2.3 seconds using blockchain technology.This process used to take more than a week in Walmart's previous system.In addition, Provenance is a firm headquartered in the United Kingdom that carried out a Pilot Study in early 2016.The study utilized blockchain technology, smart tags, and mobile phones to monitor the whole course of tuna, from its capture to its consumption by consumers.The study enabled an Indonesian company to transform their tuna fish business into a valuable asset by implementing digital identity that can be easily authenticated through an open registry.Everledger employed comparable provenance technology to monitor wine and detect any instances of fraudulent transactions (Kshetri, 2022).
Tian ( 2016) conducted a study on the progress and application of blockchain technology and RFID in the agricultural industry, highlighting their benefits and drawbacks.Additionally, a framework was suggested for the same purpose.In addition, Tian (2017) created a traceability system in real time for the agro-food supply chain by utilizing HACCP (Hazard Analysis and Critical Control Points), Internet of Things, and blockchain technology.The system was constructed using BigchainDB to ensure openness, transparency, security, neutrality, and reliability for all participants in the agro-food supply chain.In their 2018 study, Malik et al. introduced a permissioned blockchain system called "ProductChain" that aims to track the origin of food.The simulation outcome demonstrated that the trade flows remained secret among the stakeholders of the food chain, and queries were promptly answered within milliseconds.Some academics have recently combined blockchain technology with the Internet of Things (IoT) in order to enhance traceability.IoT devices were employed in these systems to record data, which were subsequently inputted into a blockchain for the purpose of tracing their origin.Caro et al. (2018) created a traceability system for the agro-food supply chain called AgriBlockIoT, which is based on blockchain technology.The authors effectively used Internet of Things (IoT) devices to consume and generate digital data throughout the supply chain.They utilized use-cases to evaluate the installation of their blockchain-based system.The implementation was carried out using two platforms, specifically Hyperledger Sawtooth and Ethereum.Lin et al., (2018) suggested implementing blockchain and IoT technology to establish traceability in the agro-food supply chain.IoT devices have completely eliminated the need for manual verification, and as a result, smart contracts have been developed to handle any potential lawsuits.In their 2018 study, Hong et al. introduced a traceability mechanism for food that utilizes an Internet of Things (IoT) and blockchain-based system.The authors suggested that traceability might be attained through the utilization of Internet of Things (IoT) devices for data capture, coupled with a consortium blockchain serving as the fundamental network.Hua et al., (2018) introduced a method that utilizes blockchain technology to establish traceability in the agro-food supply chain.The primary objective was to protect the integrity of the data and integrate the subsystems of the participating companies.Bettin-Diaz et al. (2018) introduced an innovative approach to establish a system for tracking the origin and production process of organic coffee specifically in the Colombian environment.Their approach incorporated marketing strategies, process optimization, technology, and data into a cohesive supply chain system based on blockchain technology.In their 2018 study, Kim et al. introduced a traceability mechanism called "Harvest Nestwork" that utilizes the Ethereum Platform and IoT devices to track the journey of food from the farm to the consumer.The authors elucidated the operational mechanism of smart contracts and provided a detailed explanation of the process for digitizing agricultural products and recording them on a blockchain ledger to enable traceability of their physical custody.
Existing research indicates that traceability is widely recognized as the primary application of blockchain technology in the agricultural sector.In addition, Galvez et al. (2018) conducted an analysis of the several obstacles encountered while utilizing blockchain technology for food tradability.Since a blockchain-based system lacks control over the sensors that provide data to the system, it becomes challenging to detect and prevent fraud if these sensors are altered.

Adoption of Blockchain Technology in Agriculture
Obstacles and Challenges: The use of blockchain technology in the agriculture industry confronts a number of obstacles despite its promise.Scalability and interoperability have been cited as possible obstacles to wider adoption (Androulaki et al., 2018).Regulatory compliance and data privacy issues have also been highlighted, since the open nature of blockchain technology may contradict with data protection rules (Maesa et al., 2020).Additionally, opposition from stakeholders and a lack of understanding of blockchain's advantages are barriers (Kshetri, 2017).
While blockchain technology has shown promise in a variety of global agricultural settings, its applicability in the Philippine agricultural sector, notably in the onion business, remains restricted.There is a dearth of studies addressing the possible influence of blockchain on boosting onion supply chain traceability and transparency.This research intends to address this information gap and investigate the unrealized potential of blockchain in the Philippine onion business (Swan, 2015).

Sustainable Development Goals and Blockchain in Agriculture
The Sustainable Development Goals (SDGs) of the United Nations aim for responsible consumption and production (Goal 12) and the eradication of hunger (Goal 2).These objectives are aligned with blockchain technology, which promotes transparent and sustainable supply networks.Prior study has highlighted the importance of blockchain in attaining these objectives by assuring food safety, minimizing food waste, and promoting fair trade practices (Ghosh et al., 2020).
In their 2019 article, Armas and Moralde (2019) delve into the production operations management of the broom reed industry in the Philippines.The study provides insights into optimizing production processes, enhancing efficiency, and improving overall industry performance.The findings contribute valuable knowledge to the field of production operations management.Armas et al., (2023) assess the financial viability of business models for engineered vertical hydroponics systems in sustainable onion production.This research contributes to the understanding of sustainable agricultural practices, specifically in the context of vertical hydroponics.The study provides insights into the economic feasibility of adopting innovative farming techniques.

Results and Discussions Assess the existing traceability and transparency mechanisms in the Philippine onion industry
In fulfillment of the first study goal, this meta-analysis evaluated the current traceability and transparency systems within the Philippine onion sector by methodically assessing and synthesizing the results of many studies.The objective was to provide a detailed analysis of the current condition and efficacy of these systems in assuring traceability and transparency.The results of the meta-analysis are reported in Table 1, followed by a thorough discussion and interpretation.The meta-analysis results (Table 1) provide a comprehensive evaluation of the traceability and transparency mechanisms in the Philippine onion industry.The effect sizes (ES) quantify the impact of these mechanisms on traceability and transparency, while the 95% Confidence Intervals (CI) indicate the precision of these estimates.Heterogeneity (I²) measures the degree of variability across the selected studies.
The overall effect size, represented by the random effects model, reveals a positive impact of existing traceability and transparency mechanisms, with an effect size of 0.50 (CI: 0.46, 0.54).This indicates a statistically significant improvement in traceability and transparency within the onion industry due to these mechanisms.
Studies A, B, C, D, and E consistently report positive effect sizes, ranging from 0.38 to 0.62.This consistency suggests that various mechanisms, such as tracking systems, labeling, and information sharing, contribute positively to traceability and transparency.The effect sizes are statistically significant, as evidenced by the confidence intervals that do not include zero.
Heterogeneity analyses reveal moderate variability among the selected studies, with I² values ranging from 28% to 42%.This suggests that while there is some variability in the reported effect sizes, the overall trend of positive impact remains robust.The choice of the random effects model acknowledges this variability and provides a more conservative estimate of the overall effect.
These findings align with the broader literature on traceability mechanisms in agricultural supply chains.Research studies have consistently reported that well-implemented traceability and transparency mechanisms enhance product quality, reduce inefficiencies, and build trust among stakeholders.
