PENERAPAN CONSENSUS CLUSTERING PADA PEMETAAN KETAHANAN PANGAN KOTA SERANG
ABSTRACT: Serang City was a
new town founded in 2007 from Serang Region. Food policy as a new city was
indispensable, particularly on food security. The current concept of food
security is sustainable food security supported with the Food Security Trilogy
namely food availability, access, and utilization. On the other hand, the
transient food security aspect could be used to complete the sustainable food
security. The purpose of this research was to identify the Serang City districs
based on the degree of food security because of Serang food security map
absentcy. Food security at the level of districts was described by using an
index of food security that was a sum of weight multiplication obtained from
the principle component analysis (PCA) on the both sustainable and trainsient
food security trilogy indicators. The food secure district sequence was
Kasemen, Cipocok Jaya, Walantaka, Curug, Serang, and Taktakan respectively. The
six districts were then analyzed using cluster analysis to classify the similar
districts based on the degree of food security. The cluster analysis results
were validated using consensus clustering that produced a heatmap with three
numbers of optimum clusters. The first cluster was food secure districts that
were Kasemen, Curug and Walantaka, the second cluster was food moderate secure
districts namely Taktakan, and Cipocok Jaya, and the third cluster was only
Serang District that was in food insecurity.
