Answer 1

change the 2nd query
$qrygbr = mysqli_query($koneksi, "SELECT #a:=#a+1 serial_number,t_gambar.* FROM t_gambar, (SELECT #a:= 0) AS a WHERE t_gambar.id_berita = '".$row['id']."'");
while ($rowgbr = mysqli_fetch_array($qrygbr, MYSQLI_ASSOC)) {
echo $rowgbr['serial_number']; //this is you your needed serial number
}

The following should help you understand what you need to do. I've applied a $count variable within the loop to increase as the loop continues. I've added the variable to a to show you how it works.
<?php
$koneksi = mysqli_connect('localhost', 'admbumm_DedSec', 'omnimon786.,', 'admbumm_selipin');
$qry = mysqli_query($koneksi, "SELECT * FROM t_berita ORDER BY tanggal DESC LIMIT 3");
while($row = mysqli_fetch_array($qry, MYSQLI_ASSOC)){
$qrygbr = mysqli_query($koneksi, "SELECT * FROM t_gambar WHERE id_berita = '".$row['id']."'");
$rowcount=mysqli_num_rows($qry);
$count = 1;
while ($rowgbr = mysqli_fetch_array($qrygbr, MYSQLI_ASSOC)) {
# code...
?>
<div class="carousel-item active">
<div class="card">
<div class="card-body" style="padding: 0;">
<div class="row">
<div class="col-lg-6"><img class="img-fluid" style="width: 100%;height: 100%;background-image: url(data:image/jpeg;base64,<?php echo base64_encode($rowgbr['gambar']);?>);background-position: center;background-size: cover;background-repeat: no-repeat;" /></div>
<div class="col-lg-6">
<div class="d-md-flex d-lg-flex flex-column justify-content-md-center align-items-md-center justify-content-lg-center align-items-lg-start" style="padding-top: 20px;padding-left: 10px;padding-right: 10px;height: 100%;margin-bottom: 20px;">
<h4><?php
echo $row['judul'];
?></h4>
<h6 class="text-muted card-subtitle mb-2">
<?php
echo $row['tanggal'].$rowgbr[];
?>
</h6>
<p>
<?php
echo $row['artikel'];
?>
</p>
<p>
<p>
<?php
echo $count;
?>
</p>
</p>
<div class="d-flex"></div><a class="btn btn-primary" role="button" href="bacaberita.php?id=<?php echo $row['id'] ?>">Read More</a></div>
</div>
</div>
</div>
</div>
</div>
<?php
$count = $count + 1;
}
}
mysqli_close($koneksi);
?>

Answer 3

you might want to add another variable inside your SQL Query like so
$qry = mysqli_query($koneksi, "SELECT * FROM t_berita ORDER BY tanggal DESC LIMIT 3");
to
$qry = mysqli_query($koneksi, "SELECT COUNT(*) as c,* FROM t_berita ORDER BY tanggal DESC LIMIT 3");
basically, SQL will count the total rows available and put it c. So you can just do some simple loop with c inside your PHP code
