-# Aplikasi Sistem Akademik Mobile
+# 📱 Aplikasi Absensi Akademik Berbasis Koordinat dan Foto (Mobile)
 
-Untuk 
+## 📌 Deskripsi Proyek
+Proyek ini merupakan **Tugas Project Akhir Mata Kuliah Pemrograman Mobile** yang bertujuan untuk membangun **aplikasi akademik berbasis mobile** dengan fokus pada **fitur absensi menggunakan data koordinat (GPS) dan pengambilan foto mahasiswa**.
+
+Aplikasi ini dirancang untuk meningkatkan **validitas kehadiran mahasiswa**, dengan memastikan bahwa absensi hanya dapat dilakukan apabila mahasiswa:
+1. Berada pada **lokasi yang telah ditentukan**, dan
+2. Melakukan **pengambilan foto (selfie) secara langsung saat absensi**
+
+---
+
+## 🎯 Tujuan Proyek
+- Mengimplementasikan **Location-Based Service (LBS)** pada aplikasi mobile
+- Mengintegrasikan **kamera perangkat** untuk dokumentasi absensi
+- Mencegah kecurangan absensi (titip absen)
+- Mengembangkan aplikasi mobile akademik berbasis Android
+- Melatih kemampuan perancangan dan implementasi aplikasi mobile
+
+---
+
+## 🚀 Fitur Utama
+- 🔐 **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 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 / 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)
+
+## Catatan:
+- Kembangkan project dari starter yang sudah disediakan, tidak 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
