Saran - KESIMPULAN DAN SARAN - PERANCANGAN SISTEM ABSENSI DENGAN KARTU TANDA MAHASISWA BERBASIS

BAB V KESIMPULAN DAN SARAN

5.2 Saran

Setelah mengamati data dan dilakukan analisa data maka terdapat beberapa saran untuk penelitian selanjutnya, saran tersebut diantaranya :

1. Penelitian ini dilakukan hanya fokus pada bidang ilmu kelektronikaan, maka diharapkan penelitian berikutnya dapat menggabungkan sistem alat ini kedalam sistem absensi berbasis website (menggunakan sistem login dan kemananan lainnya) sehingga sistem absensi yang dibuat akan lebih kompleks dan berkualitas.
