Abstract

Pengembangan alat ukur total dissolved solid (TDS) berbasis mikrokontroler dengan beberapa variasi bentuk sensor konduktivitas telah dilakukan. Penelitian ini untuk mengetahui pengaruh bentuk elektroda sensor konduktivitas dalam pengukuran TDS. Bentuk elektroda yang digunakan yaitu silinder pejal, silinder berongga, dan plat tipis. Nilai error hasil pengukuran nilai TDS dengan menggunakan elektroda silinder pejal, silinder berongga dan plat tipis berturut-turut dibandingkan dengan alat acuan TDS meter EZ-1 adalah 6,65%, 8,69% dan 3,83%. Berdasarkan hasil uji dan analisis data diperoleh hasil pengukuran TDS dengan menggunakan elektroda berbentuk plat tipis lebih akurat dibandingkan dengan kedua bentuk elektroda lainnya. Perubahan temperatur (dari 25°C hingga 84°C) pada air minum kemasan yang digunakan sebagai sampel menyebabkan nilai TDS berfluktuasi antara 18 ppm hingga 24 ppm.

Kata kunci : total dissolved solid (TDS), sensor konduktivitas, mikrokontroler.
