        <?php echo CHtml::endForm();?>
    </div>

</div>

the Error MEssage is

Buku has an invalid validation rule. The rule must specify attributes to be validated and the validator name

Anyone can Help This? Im very appreciated Your answer. Thanks

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'];
