Saran - PENGONTROLAN LEVEL AIR DAN PENDETEKSI KEKERUHAN KOLAM IKAN BERBASIS MIKROKONTROLLER

BAB V PENUTUP

5.2. Saran

Berdasarkan perancangan dan pembuatan alat pengontrollan kolam ikan otomatis ini, terdapat beberapa kekurangan pada alat. Untuk itu penulis memberikan beberapa saran dan masukan agar alat ini kedepannya dapat lebih baik lagi, beberapa saran diantaranya adalah sebagai berikut :

1. Untuk pengembangan selanjutnya alat ini agar memakai sensor turbidity untuk kekeruhan air sehingga nilai yang terbaca sensor lebih akurat.
