# 📱 Aplikasi Absensi Akademik Berbasis Koordinat dan Foto (Mobile)
## 📌 Deskripsi Proyek
@ -22,34 +19,52 @@ Aplikasi ini dirancang untuk meningkatkan **validitas kehadiran mahasiswa**, den
---
## 🚀 Fitur Utama
- ✍️ **Input Data Mahasiswa:** Memasukkan NPM dan Nama Lengkap.
- 📚 **Pilihan Mata Kuliah:** Memilih mata kuliah dari daftar yang tersedia.
- 📍 **Pengambilan Koordinat Lokasi:** Menggunakan GPS untuk mendapatkan lokasi presensi.
- 📸 **Pengambilan Foto Langsung:** Mengambil foto selfie sebagai bukti kehadiran.
- 🚀 **Pengiriman Data Absensi:** Mengirim semua data (profil, lokasi, foto) ke server secara *real-time*.
- ✅ **Validasi Kelengkapan Data:** Tombol kirim hanya aktif jika semua data telah terisi lengkap.
- ✨ **Antarmuka Modern:** Tampilan yang bersih dengan latar belakang gradien dan layout berbasis kartu.
- 🎉 **Konfirmasi Keberhasilan:** Menampilkan layar konfirmasi setelah absensi berhasil dikirim.
- 🔐 **Login Pengguna (Mahasiswa)**
- 📍 **Pengambilan Koordinat Lokasi (Latitude & Longitude)**
- 🏫 **Validasi Lokasi Absensi (Radius Area)**
- 📸 **Pengambilan Foto Mahasiswa Saat Absensi**
- 🕒 **Pencatatan Waktu Absensi**
- 📄 **Riwayat Kehadiran Mahasiswa**
- ⚠️ **Notifikasi Absensi Ditolak jika Tidak Valid**
---
## 🗺️ Mekanisme Absensi
1. Mahasiswa **membuka aplikasi**.
2. Mengisi **NPM, Nama Lengkap, dan memilih Mata Kuliah** pada kartu profil.
3. Aplikasi secara otomatis meminta **izin akses lokasi** dan menampilkan koordinat.
4. Mahasiswa menekan tombol **"Ambil Foto"** untuk mengambil gambar diri (selfie).
5. Setelah semua data lengkap, mahasiswa menekan tombol **"Kirim Absensi"**.
6. Data (profil, mata kuliah, foto, lokasi, dan waktu) dikirim ke server untuk divalidasi.
7. Jika berhasil, aplikasi akan menampilkan **layar konfirmasi**.
## 🗺️ Mekanisme Absensi Berbasis Lokasi dan Foto
1. Mahasiswa melakukan **login**
2. Memilih menu **Absensi**
3. Sistem meminta:
- Izin **akses lokasi**
- Izin **akses kamera**
4. Aplikasi mengambil:
- 📍 **Koordinat lokasi mahasiswa**
- 📸 **Foto mahasiswa secara real-time**
5. Sistem melakukan validasi:
- Lokasi berada dalam **radius absensi**
- Foto berhasil diambil
6. Jika valid → **Absensi berhasil**
7. Jika tidak valid → **Absensi ditolak**
---
## 📸 Pengambilan Foto Saat Absensi
- Foto diambil menggunakan **kamera depan (selfie)**
- Foto hanya dapat diambil **saat proses absensi**
- Foto disimpan sebagai **bukti kehadiran**
- Foto dapat digunakan untuk:
- Verifikasi manual oleh dosen
- Dokumentasi akademik
---
## 🛠️ Teknologi yang Digunakan
- **Platform** : Android
- **Bahasa Pemrograman** : Kotlin
- **UI Toolkit**: Jetpack Compose
- **Location Service** : Fused Location Provider
- **Bahasa Pemrograman** : Kotlin / Java
- **Location Service** :
- Google Maps API
- Fused Location Provider
- **Camera API** : CameraX / Camera2
- **Database** : Firebase / SQLite / MySQL
- **Storage** : Firebase Storage / Local Storage
- **IDE** : Android Studio

## 🔐 Izin Aplikasi (Permissions)
Aplikasi memerlukan izin berikut:
- `ACCESS_FINE_LOCATION`
- `ACCESS_COARSE_LOCATION`
- `CAMERA`
- `INTERNET`
- `WRITE_EXTERNAL_STORAGE` (jika diperlukan)

## 📂 Mockup
![mockup](Mockup.png)
gambar mockup dibuat oleh AI
## Catatan:
- Starter project ini dibuat berbantukan AI
- Kembangkan project dari starter yang sudah disediakan, jangan membuat dari awal.
- Untuk koordinat bisa ditambah/kurangi angka tertentu agar tidak memunculkan koordinat rumah masing-masing, data awal tetap dari GPS.
## Pengecekan:
- https://ntfy.ubharajaya.ac.id/EAS
- https://docs.google.com/spreadsheets/d/1jH15MfnNgpPGuGeid0hYfY7fFUHCEFbCmg8afTyyLZs/edit?gid=0#gid=0
## Webhook:
- test: https://n8n.lab.ubharajaya.ac.id/webhook-test/23c6993d-1792-48fb-ad1c-ffc78a3e6254
- production: https://n8n.lab.ubharajaya.ac.id/webhook/23c6993d-1792-48fb-ad1c-ffc78a3e6254

## ✨ Changelog
### Versi 1.1 - Penyempurnaan UI/UX & Fitur
- **UI Refresh & Latar Belakang Gradien:** Mengubah latar belakang menjadi gradien dinamis yang lebih menarik secara visual, dari `tertiaryContainer` ke `primaryContainer`.
- **Layar Konfirmasi Absensi:** Menambahkan layar konfirmasi setelah absensi berhasil, memberikan umpan balik yang lebih jelas kepada pengguna.
- **Fitur Pilihan Mata Kuliah:** Menambahkan dropdown untuk memilih mata kuliah, dan data mata kuliah kini ikut dikirim ke server.
- **Peningkatan Tata Letak:** Menggunakan `Card` untuk mengelompokkan elemen UI, membuat antarmuka lebih terstruktur dan modern.
### Versi 1.0 - Rilis Awal
- **Fungsionalitas Dasar:** Implementasi fitur absensi dengan pengambilan lokasi GPS dan foto.
- **Antarmuka Awal:** Desain antarmuka pengguna awal menggunakan Jetpack Compose.
- **Integrasi Server:** Mengirim data absensi ke server n8n.
