+1. **Login**
+   - Gunakan username dan password.
+2. **Input Data**
+   - Lihat data aktif.
+   - Input data baru dengan kolom lengkap.
+   - Pilih baris dan klik "Delete Selected Rows" untuk tandai delete.
+3. **Manajemen User**
+   - Tambah dan hapus user (kecuali ADMIN).
+4. **Data yang dihapus tidak benar-benar dihapus**, hanya ditandai `REMARK = DELETE`.
