    You need to set your own peek height on your bottom sheet behavior. Override onCreateDialog of your JemputSayaFragment:

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
    val dialog = super.onCreateDialog(savedInstanceState) as BottomSheetDialog
    val peekHeightInPixels = /*your desired height*/
    dialog.behavior.peekHeight = peekHeightInPixels
    return dialog
}

    Dialogs have a listener that is fired once the dialog is shown. The dialog cannot be shown if it isn’t laid out.

    So, in the onCreateDialog() of your modal bottom sheet (BottomSheetFragment), just before returning the dialog (or anywhere, once you have a reference to the dialog), call:

    // This listener's onShow is fired when the dialog is shown
dialog.setOnShowListener(new DialogInterface.OnShowListener() {
    @Override
    public void onShow(DialogInterface dialog) {

        // In a previous life I used this method to get handles to the positive and negative buttons
        // of a dialog in order to change their Typeface. Good ol' days.

        BottomSheetDialog d = (BottomSheetDialog) dialog;

        // This is gotten directly from the source of BottomSheetDialog
        // in the wrapInBottomSheet() method
        FrameLayout bottomSheet = (FrameLayout) d.findViewById(android.support.design.R.id.design_bottom_sheet);

        // Right here!
        BottomSheetBehavior.from(bottomSheet)
                .setState(BottomSheetBehavior.STATE_EXPANDED);
    }
});
