How to make column filled not empty while warning show up

Yups,,thanks for your help,  yes i added  value="<?php echo set_value('alamat_rumah' ); ?>" 

Before: 
<div class="form-group">
<label>Alamat</label>
<input type="text" name="alamat_rumah" class="form-control" placeholder="Masukkan alamat..">
<?php echo form_error('alamat_rumah'); ?>
</div>

<input type="text" name="alamat_rumah" value="<?php echo set_value('alamat_rumah' ); ?>" class="form-control" placeholder="Masukkan alamat..">
<?php echo form_error('alamat_rumah'); ?>
