if (!isset($_SESSION['log'])) {
    if (isset($_POST['login'])) {
        $user = mysqli_real_escape_string($koneksi, $_POST['username']);
        $pass = mysqli_real_escape_string($koneksi, $_POST['password']);

        // Membuat pernyataan SQL menggunakan prepared statement
        $stmt = $koneksi->prepare("SELECT * FROM userlogin WHERE username = ?");
        $stmt->bind_param("s", $user);

        // Menjalankan pernyataan
        $stmt->execute();

        // Mengambil hasil
        $result = $stmt->get_result();

        // Menutup prepared statement
        $stmt->close();

        // Mengambil data pengguna
        $cariuser = $result->fetch_assoc();

        // Periksa apakah password sesuai menggunakan password_verify
        if ($cariuser && Password_verify($pass, $cariuser['Password'])) {
            $_SESSION['id'] = $cariuser['id'];
            $_SESSION['username'] = $cariuser['username'];
            $_SESSION['log'] = $cariuser['login'];

            echo '<script>alert("Anda berhasil login sebagai ' . $cariuser['Username'] . '"); window.location="./index.php"</script>';
        } else {

Ada beberapa kemungkinan mengapa login gagal:

Cek koneksi databasenya. Pastikan script bisa terkoneksi dengan database dengan benar.
Cocokkanusername dan password yang dimasukkan user dengan yang ada di database. Bisa tambahkan debugging untuk mencetak isi variabel $user dan $pass sebelum query untuk memastikan datanya sesuai.
Periksa penulisan query SQL di script PHP. Pastikan query SELECT untuk mengecek username dan password sudah benar.
Cek apakah session sudah dibuat dengan benar setelah login berhasil.

$_SESSION['username'] = $username;

Script redirect setelah login berhasil tidak berjalan. Ganti dengan javascript redirect:

echo "<script>window.location='home.php'</script>";

Periksa apakah ada error di browser console. Ini bisa mengindikasikan jika ada masalah pada script PHP untuk login.
Periksa permission folder juga, pastikan webserver bisa membaca file PHP.
