Blockchain-Empowered Halal Fashion Traceability System in Indonesia

Incorporating blockchain into Halal traceability systems is developing in nature; the research aspires to examine the participation intent in blockchain-empowered Halal fashion traceability (BHFT) system via a joint framework that includes diffusion of innovation theory, institutional theory, and Halal-oriented approach. The study uses a simple random sampling method to collect the data from 165 Indonesian Halal fashion manufacturing companies. PLS-SEM is employed to examine the conceptual framework. Findings show that Halal-oriented approach significantly affects institutional pressures, while institutional pressures significantly affects perceived desirability, and perceived desirability significantly affects the participation intent. The companies operating an inclusive Halal-oriented approach will be more aware of the institutional pressures that expect them to partake in a BHFT. The paper enhances the existing literature in Halal supply chains, blockchain, operation management, and information systems via a cohesive framework and empirical insight.

BCST-APTS: Blockchain and CP-ABE Empowered Data Supervision, Sharing, and Privacy Protection Scheme for Secure and Trusted Agricultural Product Traceability System

Blockchain provides new technologies and ideas for the construction of agricultural product traceability system (APTS). However, if data is stored, supervised, and distributed on a multiparty equal blockchain, it will face major security risks, such as data privacy leakage, unauthorized access, and trust issues. How to protect the privacy of shared data has become a key factor restricting the implementation of this technology. We propose a secure and trusted agricultural product traceability system (BCST-APTS), which is supported by blockchain and CP-ABE encryption technology. It can set access control policies through data attributes and encrypt data on the blockchain. This can not only ensure the confidentiality of the data stored in the blockchain, but also set flexible access control policies for the data. In addition, a whole-chain attribute management infrastructure has been constructed, which can provide personalized attribute encryption services. Furthermore, a reencryption scheme based on ciphertext-policy attribute encryption (RE-CP-ABE) is proposed, which can meet the needs of efficient supervision and sharing of ciphertext data. Finally, the system architecture of the BCST-APTS is designed to successfully solve the problems of mutual trust, privacy protection, fine-grained, and personalized access control between all parties.

An Exploratory Study of the Purchase and Consumption of Beef: Geographical and Cultural Differences between Spain and Brazil

Beef consumption and production in Spain and Brazil are different with the consumption of beef in Brazil being three times higher than in Spain. In addition, there are variations in the economic value of production and in the traceability system. Therefore, the aim of this research was to understand the purchasing and consumption patterns using the customer behavior analysis technique of focus groups, which analyzed motivations for the consumption of beef, classifying their preferences by the intrinsic and extrinsic attributes at the time of purchase. The key aspect of the consumption of beef, both for Spanish and Brazilian consumers, was personal satisfaction/flavor. Spanish consumers were more conscious than Brazilians of the beneficial and harmful qualities that meat provides. The presence of fat was the factor that most restricted intake in both countries. The most important intrinsic attributes for Spanish and Brazilian consumers were the visual aspects of the meat: color, freshness, and the quantity and disposition of fat. The most important extrinsic characteristics were the price and expiration date. Spanish consumers see packaged meat as convenient and safe, although it is considered by Brazilians to be over-manipulated. The traceability certification on the label provides credibility to the product for the Spanish but only partially for Brazilians.

Consortium blockchains based traceability system for chicken product supply chain

In recent years, people pay increasing attention to food safety. Chicken, as the second largest meat consumer goods in China, requires high level quality traceability. However, due to the small monomer and large quantity of live poultry, it is difficult to duplicate the whole chain tracing mode of pig industry. In this paper we use HACCP (Hazard Analysis and Critical Control Points) to analyze the key control points in the chicken supply chain, and design the traceability code for each chicken product. The traceability system applies the consortium blockchains technology to realize the secure and trusted up-chaining of traceability data, which ensures the quality and safety of chicken in the market.

Prevalensi dan Tingkat Kontaminasi Listeria monocytogenes di Tambak dan Unit Pengolahan Udang Vaname (Litopenaeus vannamei) untuk Pasar Ekspor

Listeria monocytogenes adalah salah satu bakteri patogen yang dapat menyebabkan penyakit bawaan pangan. Penolakan ekspor produk udang beku Indonesia karena kontaminasi L. monocytogenes masih terjadi yang berdampak pada kerugian material bagi pelaku usaha. Tujuan penelitian ini adalah untuk mengetahui prevalensi dan tingkat kontaminasi L. monocytogenes pada produk udang beku untuk pasar ekspor. Sampel yang diambil merupakan udang segar dari tambak dan bahan baku dari bagian penerimaan di Unit Pengolahan Ikan (UPI) serta udang beku sebagai produk akhir UPI, dengan menerapkan sistem ketertelusuran. Lokasi penelitian adalah Sumatra Utara (Medan), DKI Jakarta, Jawa Timur (Surabaya dan Banyuwangi), dan Sulawesi Selatan (Makassar). Identifikasi dan enumerasi L. monocytogenes dilakukan dengan metode MPN-PCR dengan target gen hlyA (~456bp). Prevalensi L. monocytogenes pada udang vaname secara keseluruhan sebesar 6,7% (9/135 sampel), dengan prevalensi di masing-masing titik pengambilan sampel berturut-turut 6,1% di tambak, 9,6% di bahan baku, dan 4% di produk akhir, yang merupakan sampel udang dari batch yang sama. Tingkat kontaminasi L. monocytogenes pada sampel udang vaname berkisar 6,1-1.100 APM/g. Persyaratan L. monocytogenes pada bahan pangan adalah negatif/25g, sehingga sampel udang yang terkontaminasi L. monocytogenes tersebut tidak memenuhi persyaratan sebagai pangan yang aman untuk dikonsumsi berdasarkan regulasi yang berlaku di Indonesia maupun di negara lain. Kontaminasi L. monocytogenes pada udang beku kemungkinan berasal dari tambak ataupun lingkungan pengolahan. Penerapan Good Aquaculture Practices (GAP) di lingkungan tambak udang, serta Hazard Analysis Critical Control Point (HACCP) dan Good Manufacturing Practices (GMP) di UPI perlu dilakukan dengan benar sebagai upaya pengendalian kontaminasi L. monocytogenes. Selain itu, perlu dilakukan kajian lebih lanjut mengenai sumber dan titik kritis kontaminasi L. monocytogenes di sepanjang rantai pengolahan udang beku mulai dari tambak sampai produk akhir.ABSTRACTListeria monocytogenes is pathogenic bacteria that can cause foodborne illness. Rejection of frozen shrimp exports due to L. monocytogenes contamination still occurs and causes economical losses for the industries. The objective of this study was to determine the prevalence and the level of L. monocytogenes contamination in frozen shrimp for export markets. Samples collected were fresh shrimp from shrimp culture and raw material from the receiving point of fish processing plants (UPI), and frozen shrimp as the end product, by implementing a traceability system. Study locations were in North Sumatra (Medan), Special Capital Region of Jakarta, East Java (Surabaya dan Banyuwangi), and South Sulawesi (Makassar). Identification and enumeration of L. monocytogenes were carried out using the MPN-PCR method with the target gene hlyA (~456bp). The prevalence of L. monocytogenes in vanname shrimp was 6.7% (9 out of 135 samples), where 6.1%, 9.6%, and 4% of the prevalence were found in samples from shrimp culture, raw material, and end product, respectively. These samples were from the same batch. The contamination level ranged from 6.1 to 1,100 MPN/g. L. monocytogenes in food should be negative/25g, thus the contaminated samples do not meet requirements as safe for human consumption based on food regulation in Indonesia and other countries. Findings from this study suggested that shrimp culture or fish processing environment are potential sources of L. monocytogenes contamination in frozen shrimp. Therefore, the implementation of Good Aquaculture Practices (GAP) in shrimp culture environment, as well as Hazard Analysis Critical Control Point (HACCP) and Good Manufacturing Practices (GMP) in shrimp processing plant are necessary to control L. monocytogenes contamination. Further studies regarding the sources and critical points of L. monocytogenes contamination throughout the processing of frozen shrimp from shrimp culture to end product are also needed.

Improving Halal Traceability Process in the Poultry Industry Utilizing Blockchain Technology: Use Case in Indonesia

Demand for Halal food has significantly increased with the growing Muslim population and society’s interest in sustainable food production. However, there has been an increase in concerns regarding the Halal food labeling transparency process, with misleading labels found across the world. Blockchain-based traceability systems are a potential solution for current limitations in monitoring the production process of food due to its inherent decentralization and immutable nature. The technology allows stakeholders, including consumers, to promote farm-to-fork transparency, where traceability is a core component. This paper will explore the blockchain-based traceability system use case implemented by the Indonesian poultry player PT Sreeya Sewu Indonesia Tbk. Utilizing a blockchain-based system as a foundation for traceability shows promising results: data throughout the process is recorded permanently and difficult to tamper. Although the system does not eliminate the possibility of incorrect information being recorded, the same immutability characteristics will keep the new knowledge of fraud permanent if found during the audit. This layer of accountability contributes to the transparency that benefits both the consumers and stakeholders of the value chain.
