Hi RheezaldTaufik and welcome to Project Noah
Please take time to read our FAQs http://www.projectnoah.org/faq so that you know more about how to use our site.
Your suggestion on this spotting was removed because it is not applicable.
Suggestions should only be used for other users and only when you are fairly certain of the Identification, know the Genus and species for the scientific name - nothing else should be in that field - and you have a valid reference showing as much detail as possible to the user. If you only know part of the information you should just comment with the information you know.
