Notice: Undefined index: page in C:\xampp\htdocs\php_template2\input_berita_static.php on line 112
Unknown column 'page' in 'field list'

Apparently you do not have a column named 'page' in your table 'static_page'.

Line 112 is:

$page = $_REQUEST['page'];

Yes, I do have a column name page in my static_page table.

Here is the column name: id page judul isi_berita

You are asking for a form post variable $_REQUEST nothing to do with a column in the static_page.
