You have two possibilities.

If you want to allow either an empty query string or only token

RewriteCond %{QUERY_STRING} ^$ [OR]
RewriteCond %{QUERY_STRING} ^token=([^&\s]+)$ [NC]
RewriteRule ^aplikasi/(.+)\.asp$ /aplikasi.php?halaman=$1&token=%1 [L]

If you want to allow any query string

RewriteRule ^aplikasi/(.+)\.asp$ /aplikasi.php?halaman=$1 [L,QSA]
