Figure 3
The radial cladistics of phylomemetic tree of 26 area in Indonesia.
The phylomemetic diagram in radial form is shown in figure 3. In this figure the visualization
emphasizes the bifurcation of the nodes and the clustering among artifacts. It is obvious that the
buildings from the island of Java and Bali are clustered and clearly separated with other buildings.
However, there is no very apparent strong bifurcations among building from other places. This has
shown the diversity of buildings out of the island of Java spreading from Sumatera, Kalimantan,
Sulawesi, Nusa Tenggara, to the Papua Island.
To have clearer view, we also draw the dendrogram form of the phylomemetic tree (figure 4). The
axis of the figure shows the memetic distances between buildings. Interestingly, by only observing
the six features, we could see the interesting similarities among the buildings. The closely related
buildings with Jakarta, Central Kalimantan, Lampung, and Bengkulu while Southern Sumatra
clustered with those from Southern Sulawesi. Some important insights are shown in the dendogram
more than just a visualization of the branching patterns, but also the quantitative “separation” of
each cultural objects. For instance, the Aceh inspired buildings, even though it is not visualized
branching directly from other Sumatera houses, it is in fact closely related to the clustering of
Southern Sumatra and Southern Sulawesi.
From the evolutionary distances calculated based on six aspects we discussed before, it is apparent
that there is open door for further analysis by using more detailed architectural features
