Old Value/Search Value on search select button in Laravel - html

Question

i make a select button for search specific data on my table.
but there is problem when i click the button, the button doesn't remain or stay from past request value that i click, or it reset back to select all
so this is my form in my blade file
<form action="">
<select class="form-select" name="rumah_id" id="rumah_id">
<option value="">Select All</option>
#foreach($rumahs as $rumah)
#if(old('rumah_id') == $rumah->id)
<option value="{{ $rumah->id }}">{{ $rumah->alamat }}</option>
#else
<option value="{{ $rumah->id }}">{{ $rumah->alamat }}</option>
#endif
#endforeach
</select>
</form>
this is my Controller
public function index(Request $request){
$rumah = Rumah::all();
$mobil = Mobil::with(['rumah'])->orderBy('rumah_id', 'asc')
->when($request->rumah_id != null, function($q) use($request){
return $q->where('rumah_id', 'like', '%'. $request->rumah_id. '%');
})
return view('mobil/index',[
'mobils' => $mobil,
'rumahs' => $rumah,
]);
}
also this is my migration database for rumah look like
Schema::create('rumahs', function (Blueprint $table) {
$table->id();
$table->string('alamat');
$table->timestamp('published_at')->nullable();
$table->timestamps();
});

Try this :
<select class="form-select" name="rumah_id" id="rumah_id">
<option value="">Select All</option>
#foreach($rumahs as $rumah)
<option value="{{ $rumah->id }}" {{ old('rumah_id') == $rumah->id ? 'selected' : '' }}>{{ $rumah->alamat }}</option>
#endforeach
</select>
