I still confusd abaout the magento 2. I'am new in magento.
my question is How to sending data from the layout form to the controller ?

this my code ui_component/ppp.xml

<?xml version="1.0" encoding="UTF-8"?>
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
<argument name="data" xsi:type="array">
 <item name="js_config" xsi:type="array">
 <item name="provider" xsi:type="string">ppp_duplicateStore_form.ppp_duplicateStore_form_data_source</item>
 </item>
 <item name="deps" xsi:type="string">ppp_duplicateStore_form.ppp_duplicateStore_form_data_source</item>
 <item name="namespace" xsi:type="string">ppp_duplicateStore_form</item>
 <item name="label" xsi:type="string" translate="true">Store list</item>
 <item name="template" xsi:type="string">templates/form/collapsible</item>
 <item name="buttons" xsi:type="array">
 <item name="saveDuplicateStore" xsi:type="string">PppDuplicateStoreBlockAdminhtmlDuplicateStoresave</item>
 </item>
</argument>

<dataSource name="ppp_duplicateStore_form_data_source">
 <argument name="dataProvider" xsi:type="configurableObject">
 <argument name="class" xsi:type="string">PppDuplicateStoreModelDataProvider</argument>
 <argument name="name" xsi:type="string">ppp_duplicateStore_form_data_source</argument>
 <argument name="primaryFieldName" xsi:type="string">store_id</argument>
 <argument name="requestFieldName" xsi:type="string">store_id</argument>
 <argument name="data" xsi:type="array">
 <item name="config" xsi:type="array">
 <item name="submit_url" xsi:type="url" path="ppp/duplicate_store/save"/>
 </item>
 </argument>
 </argument>
 <argument name="data" xsi:type="array">
 <item name="js_config" xsi:type="array">
 <item name="component" xsi:type="string">Magento_Ui/js/form/provider</item>
 </item>
 </argument>
</dataSource>
<fieldset>
 <settings>
 <label/>
 </settings>
 <field name="store" formElement="select">
 <argument name="data" xsi:type="array">
 <item name="config" xsi:type="array">
 <item name="source" xsi:type="string"> </item>
 </item>
 </argument>
 <settings>
 <validation>
 <rule name="required-entry" xsi:type="boolean">true</rule>
 </validation>
 <!-- <elementTmpl>ui/grid/filters/elements/ui-select</elementTmpl> -->
 <dataType>text</dataType>
 <label translate="true">select store</label>
 <dataScope>store</dataScope>
 </settings>
 <formElements>
 <select>
 <settings>
 <options class="PppDuplicateStoreModelSourceStore"/>
 </settings>
 </select>
 </formElements>
 </field>
</fieldset>

And this my Controller/Adminhtml/Duplicate/Store/Save.php

<?php
namespace PppDuplicateStoreControllerAdminhtmlDuplicateStore;
class Save 
 public function execute() 
 echo json_encode("test is true");exit();
 

this my DuplicateStore/Block/Adminhtml/Duplicate/Store/Save.php

<?php
 namespace PppDuplicateStoreBlockAdminhtmlDuplicateStore;
 use MagentoFrameworkViewElementUiComponentControlButtonProviderInterface;

 class Save implements ButtonProviderInterface
 
 /**
 * @return array
 */
 public function getButtonData()
 
 return [
 'label' => __('Save kri'),
 'class' => 'save primary',
 'data_attribute' => [
 'mage-init' => [
 'buttonAdapter' => [
 'actions' => [
 [
 'targetName' => 'ppp_duplicateStore_form.ppp_duplicateStore_form',
 'actionName' => 'save',
 'params' => [
 true
 ]
 ]
 ]
 ]
 ]
 ],
 'sort_order' => 40,
 ];

save button inside ui_component/ppp.xml

<item name="saveDuplicateStore" xsi:type="string">PppDuplicateStoreBlockAdminhtmlDuplicateStoresave</item>

I tried to show out the text inside json_encode but when I clicked the saveDuplicateStore button only showed 404 not found..
