“…This study requires the collection of primary data obtained directly through interviews with questionnaires from house to house, participants attending FGDs to depth interviews with key informants, and secondary data in the form of results and based on information available in local governments. Some of the analyzes used in the SNA to discuss food stability are; a) Baseline network [26], b) Community Detection [20], c) Hub andAuthority [27], d) Degree, [28], e) Centrality [21] and f) Betweeness [21,22]. Then visualized with an R diagram, deepening the analysis with in-depth interviews with key informants.…”

This study aims to explore social networks and interactions between networks in strengthening food stability in maritime villages in coastal areas. The geographical condition of the region has become one of the triggers for food instability and food security problems in coastal areas. This study uses the method of Social Network Analysis (SNA). Data processing uses R to visualize the role of stakeholder centrality. The analysis used is the analysis of baseline network, degree, and betweenness centrality. The value of modularity is an indicator of increasing or decreasing community networks. The number of nodes and links identifies the actors in the network and the interactions between actors. The results showed that social networks have an essential role in food stability. The private sector is a key actor in food stability in maritime villages. Is indicated by the modularity value of 0.43 (>0), which connects to 30 social network nodes and 62 links to food stability in maritime villages in the coastal area of Bintan Regency.

“…Where is the normalized degree centrality of the actor (node) , is the degree of the actor (node) , and is the total number of actors. Degree centrality is also helpful for measuring the popularity of each node, where the higher the popularity of a node, the higher the access to other nodes to exchange information information (Farhan et al, 2019) Equation ( 3) Equation ( 3) calculates the centrality between an actor or . Where is the betweenness centrality of actor (node) , is the number of geodesics from actor to actor that contain actor , is the number of geodesics from actor to actor , and is actor (node) , , .…”

This study analyzes how social networks can connect and interact to strengthen food accessibility for poor households on Mapur Island, one of the small and outermost islands in Indonesia. Data collection used interviews with eighteen recipient households of the Family Hope Program (PKH) and Focus Group Discussions with eighteen key informants. Data were analyzed using R analysis and social network analysis. This study found that the level of access to food for PKH households and their social networks was very low and short. His dependence on rice assistance from the government and being in debt to ‘Patron’ became very strong. Of all identified communities, the same pattern was found, and a strong mutual relationship was with ‘Patron.’ The role of ‘Patron’ in the food access network is an intermediary and central role that connects many entities and activities to meet community needs. The interaction between the Regional Logistics Agency stopped at the liaison between the ‘Patron’ and the village government that distributed the assistance. The village food access network is very dependent on the network owned by ‘Patron.’ Government intervention through policies and strengthening food institutions can play a key role in helping to facilitate access to food needs on the island.

“…7) The Hubs and Authority centrality assigns hub and authority scores to each node (León, 2013;Xutao, Michael & Yunming, 2012;Kleinberg, 1999). Hub and Authority centrality focus on the structure of the network and determine its importance according to their positions on a graph (Marra et al, 2015) and is affected by the total relations that occur outside the node (Farhan, Darwiyanto & Asror, 2019). The node is a hub when it has edges to authoritative nodes.…”

The complexity of the vapour intrusion (VI) transport pathway has received an ever-increased interest worldwide, and an improved and consolidated understanding of the VI issue requires collaboration between international research groups. This study uses the social network analysis methodology, applied to bibliometric authorship for VI research, to discover trends in collaboration, identify lead scientists, organisations, and countries. Furthermore, some of the external factors influencing the collaboration and productivity were assessed. The data suggests that the global research network for VI produced over a time span of 54 years 566 publications via 157 sources. The research network is composed of 437 organisations and 1053 authors from 33 countries. This suggests an increasingly active international collaborative research effort. However, inter-continental cooperation is much less than continental. The top five most central countries in the network are the USA, followed by Canada, China, The Netherlands, and Italy. The researchers with the most publications are from these five countries as well as the top organisations. The social network analysis conducted shows a good approximation of the collaborative structure for the key countries, organisations and researchers involved. Since 2010, the research community has become more stable.
