add the line to fetch results in comments

<?php include "koneksi.php";
    $kdj=$_POST['kdj'];
    $id=$_POST['id'];
    $qty = $_POST['qty'];
    $kodelagi = mysql_query("Select kd_jual from nota order by id_nota DESC LIMIT 1");
    ////////////////// add these two lines to fetch the results
    $row = mysql_fetch_array($kodelagi);
    $kodelagi1 = $row['kd_jual'];
    //////////////////
    if((!empty($id)) && (!empty($kdj)) && (!empty($qty)))
    {
    $query = mysql_query("INSERT INTO nota (id_item,qty,kd_jual)
    values ('$id','$qty','$kodelagi1');");    ////// $kodelagi1 fetched value
    ?><script language="Javascript">;
    document.location = 'transaksi.php' </script><?php
    }else 
    {
    print "<script>alert('Maaf, tidak boleh ada field yang kosong !');
    javascript:history.go(-1);</script>";
    }?>
