Abstract

At present the measurement of blood sugar still uses an invasive tool, this disrupts the patient's comfort and can cause infection and pain. So that a non-invasive tool is needed to measure blood sugar. Tool testing was done by measuring blood sugar levels in 35 patients and seeing a correlation between the value of blood sugar levels with ADC. The test results showed that the value of changes in blood sugar levels followed y = -0.146x + 164.89 Coefficient value R = 0.9233 The value of the accuracy of the tool was 91.086% and the precision of 94.3026%. Blood sugar measuring devices that have been designed to monitor the blood sugar of users by using the internet. This blood sugar meter cannot be used as a reference for the actual blood sugar level. However, the realization of this tool can still determine a rough estimate of the high and low levels of sugar in the blood.

Abstract

Air merupakan bagian sangat penting untuk kelangsungan hidup makhluk hidup. Oleh karena itu perlu mengetahui kualitas air yang memenuhi standar kesehatan, maka pada penelitian ini dirancang sistem monitoring kejernihan air menggunakan sensor turbidity pada tandon berbasis internet of thing. Sistem ini memanfaatkan aplikasi Blynk pada platform Android untuk melakukan sistem monitoring. Parameter fisika yang diuji berupa tingkat kekeruhan air, pH dan suhu menggunakan sensor turbidity SEN0189, pH dan sensor suhu DS18B20. Pengujian keseluruhan parameter dilakukan di Kantor Kecamatan Kasemen. Hasil rata-rata tingkat kekeruhan berkisar 25-27 NTU, nilai tersebut sudah sesuai dengan standar mutu air bersih menurut KEPMENKES RI No/32/2017 yaitu sebesar 25 NTU. Hasil pengujian nilai pH air tercatat antara 5-6, yang menunjukkan sifat asam, dan suhu air bervariasi antara lain 28°C-32°C bergantung pada kondisi cuaca pada saat pengujian. Sistem monitoring ini bekerja dengan baik di cuaca hujan (28°C) dan cuaca cerah (32°C).
