is 2 clusters. With the initial centroid values that are formed
automatically, they are as follows:
Tabel 1. Early Centroid.
Cluster Number of Population Medical
Cases Density Facility
1 32.12500 2283.6250 92.75000
2 22.15385 821.2308 90.69231

Based on Table. 1, the mean or centroid for each of the variables in
the cluster group. This initial centroid is the data that became the
center point of the first cluster in determining the grouping of dengue
disease spread in East Lombok Regency. For example, the number
of cases in cluster 1 centroid is 32.12500, population density in cluster
1 is 2283.6250 and health facilities in cluster 1 are 92.75000 and
likewise with other clusters.
3.3.1 Algorithm K-Means Clustering
To determine the analysis of the level of spread of dengue
transmission in East Lombok Regency using RStudio, with the results
of the analysis as follows:
Table 2. Centroid Value.
Cluster Number of Number of Population Medical
Members Cases Density Facility
1 13 32.1 2284 92.8
2 8 22.2 821 90.7
After analyzing with the K-Means algorithm using RStudio, the results
were obtained, namely: there are two clusters, namely C1, and C2.
Where C1 is the rate of spread of dengue disease in East Lombok
Regency with a high category there are 13 districts and C2 with a low
category there are 8 districts. The formed graph can be seen in
Figure. 2.
