Answer 1

Try 'autocomplete' => 'off' in your date picker options:

<?= DatePicker::widget([
        'type' => DatePicker::TYPE_RANGE,
        'model' => $model,
        'attribute' => 'tgl_mulai',
        'attribute2' => 'tgl_selesai',
        'options' => ['placeholder' => 'Start date','autocomplete' => 'off'],
        'options2' => ['placeholder' => 'End date'],

        'form' => $form,
        'pluginOptions' => [
            'format' => 'dd-mm-yyyy',
            'autoclose' => true,
        ]
    ]); ?>

You may have to turn off the autocomplete in your form element
