您有一个拼写错误，它不是refrences，而是references，因此请更改以下两行：

$table->foreign('id_kategori')->refrences('id')->on('kategori')->onDelete('CASCADE');
$table->foreign('id_pelanggan')->refrences('id')->on('pelanggan')->onDelete('CASCADE');

与此：

$table->foreign('id_kategori')->references('id')->on('kategori')->onDelete('cascade');
$table->foreign('id_pelanggan')->references('id')->on('pelanggan')->onDelete('cascade');
