 # 📱 Aplikasi Absensi Akademik Berbasis Koordinat dan Foto (Mobile)
 
-## 👤 Identitas Mahasiswa
-- **Nama:** Dirson Ali Wardana
-- **NPM:** 202310715246---
-
 ## 📌 Deskripsi Proyek
-Proyek ini merupakan **Tugas Akhir / Project Akhir Mata Kuliah Pemrograman Mobile**. Aplikasi ini dikembangkan untuk mengelola absensi mahasiswa secara cerdas dengan validasi ganda: **Lokasi GPS (Geofencing)** dan **Verifikasi Wajah (Selfie)**.
+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 memastikan kehadiran mahasiswa valid apabila mahasiswa berada dalam radius lokasi kampus dan melakukan pengambilan foto selfie sebagai bukti kehadiran fisik yang kemudian dikirimkan ke server pemantau (n8n & Google Sheets).
+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**
 
 ---
 
-## 📝 Change Log (Modifikasi & Pengembangan)
+## 🎯 Tujuan Proyek
-Berdasarkan *starter project* yang disediakan, berikut adalah catatan perubahan signifikan yang telah saya implementasikan:
+- Mengimplementasikan **Location-Based Service (LBS)** pada aplikasi mobile
-
+- Mengintegrasikan **kamera perangkat** untuk dokumentasi absensi
-I. **Dropdown Mata Kuliah & Integrasi Data**: Menambahkan fitur pilihan mata kuliah dan memastikan data `namaMatkul` terkirim dengan benar ke server melalui payload JSON.
+- Mencegah kecurangan absensi (titip absen)
-II. **Fragment Preview (History Logic)**: Mengimplementasikan `PreviewFragment` yang merangkum seluruh data (Foto, Koordinat, Timestamp) sebelum dikirim, serta menambahkan logika penyimpanan otomatis ke `DataHolder.historyList` setelah pengiriman berhasil.
+- Mengembangkan aplikasi mobile akademik berbasis Android
-III. **Konversi Base64**: Mengimplementasikan fungsi `base64ToBitmap` dan pengiriman `foto_base64` agar foto selfie mahasiswa dapat tersimpan dan dilihat di server.
+- Melatih kemampuan perancangan dan implementasi aplikasi mobile
-IV. **Modernisasi UI (Material Card & Progress Bar)**: Menggunakan `MaterialCardView` untuk tampilan foto preview dan menambahkan `ProgressBar` (Loading) untuk memberikan feedback visual saat proses pengiriman data ke server.
-V. **Network Threading**: Menggunakan `kotlin.concurrent.thread` untuk menangani proses pengiriman data ke Webhook agar aplikasi tidak *freeze* (ANR) saat melakukan request jaringan.
 
 ---
 
 ## 🚀 Fitur Utama
-- 🔐 **Login Mahasiswa**: Autentikasi otomatis dengan data profil tetap (Hardcoded).
+- 🔐 **Login Pengguna (Mahasiswa)**
-- 🎓 **Mata Kuliah Selector**: Memilih mata kuliah aktif sebelum melakukan absensi.
+- 📍 **Pengambilan Koordinat Lokasi (Latitude & Longitude)**
-- 📍 **GPS Tracking**: Pengambilan koordinat Latitude dan Longitude secara presisi.
+- 🏫 **Validasi Lokasi Absensi (Radius Area)**
-- 📸 **Selfie Verification**: Pratinjau foto selfie sebelum data dikirim ke server.
+- 📸 **Pengambilan Foto Mahasiswa Saat Absensi**
-- 📄 **Real-time History**: Daftar riwayat absensi yang langsung terupdate menggunakan `RecyclerView` / `LazyColumn`.
+- 🕒 **Pencatatan Waktu Absensi**
-- 📡 **Webhook Integration**: Pengiriman data langsung ke sistem n8n Ubhara Jaya.
+- 📄 **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
-- **Bahasa**: Kotlin
+- **Platform** : Android
-- **UI Framework**: Android XML (View System) & Jetpack Compose (Interoperability).
+- **Bahasa Pemrograman** : Kotlin / Java
-- **Network**: `HttpURLConnection` dengan format data **JSON**.
+- **Location Service** :
-- **Kamera**: CameraX API.
+    - Google Maps API
-- **Lokasi**: Fused Location Provider Client.
+    - Fused Location Provider
-- **Data Manager**: `DataHolder` (Singleton) untuk manajemen data antar layar.
+- **Camera API** : CameraX / Camera2
-
+- **Database** : Firebase / SQLite / MySQL
----
+- **Storage** : Firebase Storage / Local Storage
-
+- **IDE** : Android Studio
-## 🗺️ Mekanisme Absensi
-1. Mahasiswa memilih mata kuliah.
-2. Aplikasi mengambil lokasi dan mahasiswa melakukan foto selfie.
-3. Di halaman **Preview**, mahasiswa memvalidasi data (Nama, NPM, Lokasi, dan Foto).
-4. Klik **Submit**: Data dikonversi ke JSON dan dikirim ke Webhook.
-5. Jika berhasil (Response 200), data otomatis masuk ke menu **Riwayat**.
 
 ---
 
 ## 🔐 Izin Aplikasi (Permissions)
-Aplikasi memerlukan akses berikut:
+Aplikasi memerlukan izin berikut:
-- `android.permission.CAMERA`: Untuk mengambil foto selfie.
+- `ACCESS_FINE_LOCATION`
-- `android.permission.ACCESS_FINE_LOCATION`: Untuk validasi lokasi presisi.
+- `ACCESS_COARSE_LOCATION`
-- `android.permission.INTERNET`: Untuk mengirim data absensi ke n8n.
+- `CAMERA`
+- `INTERNET`
+- `WRITE_EXTERNAL_STORAGE` (jika diperlukan)
 
 ---
 
-## ⚠️ Disclaimer & Catatan
+## 📂 Mockup
-- **PENGGUNAAN AI**: Proyek ini dikembangkan dengan bantuan **Kecerdasan Buatan (AI)** (ChatGPT/Claude) dalam proses debugging Gradle, perbaikan error `XMLStreamException`, dan penyusunan struktur pengiriman data JSON pada `PreviewFragment.kt`.
+![mockup](Mockup.png)
-- **PENGEMBANGAN**: Aplikasi ini merupakan hasil modifikasi intensif dari *starter project* yang disediakan untuk memenuhi standar capaian project akhir EAS 2025/2026.
