Abstract

Using minimum spanning tree technique (MST), this exploratory research was done to optimize the interrelation and hierarchical network design of Indonesian’s airports. This research also identifies the position of the Indonesian’s airports regionally based on the ASEAN Open Sky Policy 2015. The secondary data containing distance between airports (both in Indonesia and in ASEAN), flight frequency, and correlation of Gross Domestic Regional Product (GDRP) for each region in Indonesia are used as inputs to form MST networks. The result analysis is done by comparing the MST networks with the existing network in Indonesia. This research found that the existing airport network in Indonesia does not depict the optimal network connecting all airports with the shortest distance and maximizing the correlation of regional economic potential in the country. This research then suggests the optimal networks and identifies the airports and regions as hubs and spokes formed by the networks. Lastly, this research indicates that the Indonesian airports have no strategic position in the ASEAN Open Sky network, but they have an opportunity to get strategic positions if 33 airports in 33 regions in Indonesia are included in the network.

Abstract

This research was perfomed to provide a comprehensive Systematic Literature Review (SLR) on the mutually beneficial link between Lean and Knowledge Management (LKM). The primary focus was to highlight the crucial role of LKM as an enabler in empowering perishable food supply chains (PFSC) to effectively embrace traceability technology, ensuring the integrity of halal supply chains. The research was carried out using the SLR method and adhered to the procedures of the Preferred Reporting for Systematic Reviews and Meta-Analyses (PRISMA). In total, 65 articles from the Scopus database, published in various journals over 22 years were chosen, mapped, and evaluated. Furthermore, there were several featured forms of mutual collaboration between Lean and Knowledge Management (KM). The implementation of LKM in halal supply chain traceability for perishable food was still absent from the literature. Efficient (lean) KM processes for business actors turned knowledge into added value for the PFSC. The vital role of LKM as an enabler for PFSC in adopting traceability technology, which is characterized as fast-changing technology and highly knowledge-centric, is by eliminating wasteful knowledge so could advance responsiveness, efficiency, and flexibility. Considering the important role of LKM as an enabler of PFSC to address complex challenges in traceability technology adoption, collaborative interdisciplinary research is needed. Academic publications exploring the incorporation  of lean and KM in the context of PFSC were relatively scarce. This SLR represented one of the pioneering efforts to investigate the amalgamation and its potential to overcome obstacles and inhibitors in the adoption of traceability technology.
