Answer 1

Pleas edit the first line, probably you wanted there 'required'
array('judul, penulis','required'),
And this is not needed:
$model->judul =$_POST['Buku']['judul'];
$model->penulis =$_POST['Buku']['penulis'];
instead you can use the mass-assignment: http://www.yiiframework.com/wiki/161/understanding-safe-validation-rules/
$model->attributes=$_POST['Buku'];

Answer 2

In Your Model class method rules first rule is invalid:
array('judul, penulis') -> no validation rule specified.
Try at least:
array('judul, penulis', 'required')
