# ✅ IMPLEMENTASI SELESAI - Admin-Only System

## 📊 Summary of Changes

Aplikasi **Klasifikasi Kematangan Tomat** telah diubah menjadi **Admin-Only System** (bukan public multi-user).

---

## 🔧 Changes Made

### 1. ✅ User Model Updated
**File:** `app/Models/User.php`

```php
protected $fillable = [
    'name',
    'email', 
    'password',
    'role',              // ← Added
    'email_verified_at', // ← Added
];
```

**Alasan:** Allow role field untuk admin CRUD operations

---

### 2. ✅ Database Migration Created
**File:** `database/migrations/2025_02_05_cleanup_users_admin_only.php`

**Fungsi:**
- Hapus semua user dengan role 'user'
- Set role 'admin' untuk semua user yang tersisa
- Prepare database untuk admin-only system

**Jalankan:**
```bash
php artisan migrate
```

---

### 3. ✅ Login Page Updated
**File:** `resources/views/login.blade.php`

**Perubahan:**
```blade
<!-- Lama -->
<p>Halaman ini khusus untuk admin sistem</p>

<!-- Baru -->
<p>Belum punya akun admin? 
   <a href="{{ route('admin.manage-admin') }}">
     Hubungi administrator
   </a>
</p>
```

**Alasan:** Direct link ke admin management untuk tambah admin baru

## 🗄️ Database Structure

**Users Table (Admin Only):**
```
- id (INT)
- name (VARCHAR)
- email (VARCHAR) - UNIQUE
- password (VARCHAR) - hashed
- role (VARCHAR) = 'admin' (ALWAYS)
- email_verified_at (TIMESTAMP)
- remember_token (VARCHAR)
- created_at (TIMESTAMP)
- updated_at (TIMESTAMP)
```

**Note:** Tidak ada role 'user', semua adalah 'admin'
