Abstract

 The procurement system for goods and services in the maritime sector often faces serious challenges related to transparency, accountability, and efficiency, which may lead to corrupt practices and operational inefficiencies. Blockchain technology emerges as an innovative solution that offers a decentralized and immutable record-keeping system, thereby enhancing trust and integrity in procurement processes. This study aims to analyze the role of blockchain technology in improving transparency, accountability, and efficiency in the procurement system within Indonesia’s maritime sector. By using a qualitative approach, namely by collecting qualitative data through in-depth interviews with stakeholders in the maritime industry, shipping companies, port authorities, and logistics providers. The findings indicate that blockchain implementation enhances information transparency, strengthens accountability mechanisms, and accelerates processes while reducing errors in procurement. The study concludes that blockchain technology holds strategic potential to drive procurement reform in the maritime sector toward better, more efficient, and integrity-based governance.

Abstract

The transformation of maritime supply chains into more sustainable systems presents both a challenge and a strategic opportunity to enhance the competitiveness of marine products. This study explores the integration of sea transportation based on green logistics principles as an approach to generating added value in maritime product marketing. A qualitative case study method was employed, focusing on seafood processing and distribution businesses in the coastal areas of Central Java. Data were collected through in-depth interviews, field observations, and document analysis, and processed using triangulation techniques. The findings reveal that implementing green logistics in sea transportation significantly reduces logistics costs, minimizes carbon emissions, and accelerates product distribution to key markets. Moreover, the integration of information systems and renewable energy-based fleet management has proven to improve operational efficiency and enhance the sustainability image of the products in the eyes of consumers. The study underscores that collaboration among government bodies, industry players, and local communities is essential in developing environmentally friendly and economically valuable maritime transport systems. In conclusion, the green logistics strategy contributes not only to ecological benefits but also to the increased competitiveness of maritime products in both domestic and international markets.

Abstract

Stunting is a chronic nutritional problem that has long-term impacts on the quality of human resources in Indonesia, particularly in Pemalang Regency, Central Java. The government has implemented various nutrition intervention policies, one of which is the Free Nutritious Meal Program (MBG) as an effort to improve the nutritional status of the population, especially school-age children, toddlers, and pregnant women. This study aims to analyze the policy of the Free Nutritious Meal Program (MBG) as a nutrition intervention instrument in stunting prevention. This research uses a qualitative approach with a descriptive-analytical method. Data were collected through interviews, observations, and documentation involving informants from the Health Office, Education Office, schools, health workers, posyandu cadres, and beneficiary communities. Data analysis was conducted using the Miles and Huberman interactive model, which includes data reduction, data display, and conclusion drawing. The validity of the data was tested through source and method triangulation The results show that the MBG program has a positive impact in improving community access to nutritious food, enhancing children’s dietary patterns, and increasing parents’ nutrition awareness. The program also strengthens cross-sector collaboration between local government, schools, and health facilities in efforts to reduce stunting. However, the implementation of the program still faces several challenges, such as limited supervisory personnel, budget constraints, uneven distribution, and low nutrition literacy among the community. In addition, the effectiveness of the program in significantly reducing stunting rates still requires long-term evaluation due to the multidimensional nature of stunting determinants. In conclusion, the Free Nutritious Meal Program has strong potential as a nutrition intervention policy instrument in stunting prevention in Pemalang Regency. However, its success largely depends on strengthening governance, cross-sector coordination, capacity building, and policy sustainability. Therefore, integration with other health and social intervention programs is needed to achieve optimal stunting reduction.

Abstract

Background: The global maritime supply chain faces enormous pressure to undergo digital transformation amid demands for efficiency and resilience. Blockchain and Artificial Intelligence (AI) have emerged as key technologies, yet their integration has rarely been systematically reviewed. Objective: This study aims to synthesize scientific evidence on Blockchain-AI integration models, their contributions to maritime supply chain efficiency and resilience, and the factors influencing implementation.Method: A systematic literature review (SLR) following the PRISMA protocol was conducted. Searches were performed in Scopus, Web of Science, and Google Scholar (2019 2024) using structured keywords. A total of 128 articles from 152 initial references were thematically analyzed. Results: Three main integration patterns were identified: off-chain AI with on-chain smart contracts, on-chain federated learning, and hybrid oracle-based integration. Blockchain-AI integration has been proven to reduce turnaround time by 25 35%, document costs by 28 44%, and increase supply chain visibility by up to 92%. Resilience improved through disruption prediction (85 94% accuracy), automated rerouting, and reduction of recovery time by up to 57%. The main barriers are interoperability, regulation, and migration costs. Simultaneous Blockchain-AI integration enhances both efficiency and resilience of maritime supply chains, but requires interoperability standards and regulatory support.
