Mdl = fitcknn(ciri_uji, target_uji, 'NumNeighbors', 2, 'Standardize', 1);
Y = target_uji;
predictedLabels = resubPredict(Mdl);
% Create confusion matrix
figure;
confusionchart(Y, predictedLabels);

According to the confusionchart documentation, you can specify the parent that the confusion chart will be created in, by specifying the appropriate parent container as the first argument in your call to confusionchart.
For instance, to put it directly in your app's uifigure, you can say:
confusionchart(app.UIFigure, Y, predictedLabels)
assuming the app's uifigure is called app.UIFigure. You could also put it in a panel or tab, etc., inside that uifigure.

What I mean is how can the confusionchart be displayed in app.uiaxes, instead of displaying it as a figure

Sorry, I should have been more clear. You cannot make a confusion chart inside a uiaxes.
The documentation I linked to states that a confusion chart's parent is "a Figure, Panel, Tab, TiledChartLayout, or GridLayout object". Note that axes/uiaxes is not listed as a possibility.
So: you can put a confusion chart in your app (which I think is what you want), but not in a uiaxes (which is what you asked about).
Try this and see what happens:
confusionchart(app.UIFigure, Y, predictedLabels)
