Sistem Presensi Dosen Menggunakan IMEI dan GPS Smartphone dengan Data Terenkripsi
Abstrak
Perbaikan mutu pendidikan tidak hanya dipandang dari sisi kehadiran mahasiswa di kelas tetapi juga yang tidak kalah penting adalah kehadiran tatap muka dengan dosen di kelas. Sistem presensi ini hanya diperuntukkan bagi dua pengguna, yaitu admin dan dosen, di mana admin melakukan pengolahan data dan laporan, sedangkan dosen melakukan presensi melalui perangkat smartphone dengan memanfaatkan IMEI (International Mobile Equipment Identity), dan GPS (Global Positioning System). Keamanan aliran data dalam sistem presensi ini menggunakan algoritme cipher aliran dengan metode pengacakan kunci, yaitu: Hamming code paritas ganjil, tent map, dan session keys. Hasil penelitian menunjukkan bahwa sistem sudah cukup aman karena dibangun menggunakan arsitektur three-tier, adanya security check dari perangkat lunak sistem, dan aliran data terenkripsi dengan nilai korelasi antara plaintext dan ciphertext yang sangat lemah. Sistem presensi ini juga handal dalam mempertahankan komunikasi data antara client dan server selama terjadi pemutusan koneksi internet dan/atauGPS. Laporan pertemuan dosen ini dapat dijadikan masukan bagi decision maker dalam menentukan keabsahan perkuliahan.
