First of all it would be easier if you submitted the form to the same page.

So change

<form id="form1" name="form1" method="post" action="reg.php">

and

<button type="submit">Sign-up</button>

to

<form id="form1" name="form1" method="post" action="register.php">

and

<button type="submit" name="submit">Sign-up</button>

then just add a error checking with an array or messages

<?php 
$Error = array("email" => "", "pwd" =>"Passsword must match"); //Default error messages are blank!
if(isset($_POST['submit'])){//reg.php code below
$email=$_POST['email'];
if(empty($email)) $Error['email'] = "No email Entered!"; //err if no email entered!
$pwd1=$_POST['pwd1'];
$pwd2=$_POST['pwd2'];
if(pwd1 != pwd2) $Error['pwd'] = "Passwords muct match"; //err pwd1 is not the same as pwd2
$tgl=$_POST['tgl'];
$bln=$_POST['bln'];
$thn=$_POST['thn'];
$tgl_lahir=$tgl.'-'.$bln.'-'.$thn;
$jekel=$_POST['jekel'];
$alamat=$_POST['alamat'];
$kota=$_POST['kota'];
$propinsi=$_POST['propinsi'];
}else{
$email="";
$pwd1="";
$pwd2="";
$tgl=0;
$bln=0;
$thn=0;
$tgl_lahir=$tgl.'-'.$bln.'-'.$thn;
$jekel="";
$alamat="";
$kota="";
$propinsi="";
}
?>

Then update the form to display the values and errors

ie

<input type="text" name="email" id="email" value="<?php echo $email; ?>"/><?php echo $Error['email']; ?>
