You can add "addbefore" attribute to your UI component form field.
Follow this code:

<field name="xxxxx"  sortOrder="50" >
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="dataType" xsi:type="string">text</item>
                <item name="label" xsi:type="string" translate="true">xxxxx xxxxx</item>
                <item name="formElement" xsi:type="string">input</item>
                <item name="source" xsi:type="string">ordercombine</item>
                <item name="dataScope" xsi:type="string">xxxxx</item>
                <item name="default" xsi:type="string">1</item>
                <item name="addbefore" xsi:type="string">$</item>
            </item>
        </argument>
    </field>
