Abstract

Gout disease or commonly known as gout arthritis is a disease caused by the accumulation of monosodium urate crystals in the body. Monitoring blood uric acid levels is currently still using invasive techniques by taking blood samples to be included in the test strip, this invasive technique measurement requires money and time to come to health clinics so that many people cannot monitor blood uric acid levels on a regular basis. This study aims to develop a measuring instrument for monitoring blood uric acid levels using sensors by utilizing the absorption and reflectance of infrared rays so that gout sufferers and other individuals can monitor blood uric acid levels regularly and are easy to use. The method of developing non-invasive techniques focuses on monitoring blood uric acid levels using a NIR sensor with an IR LED with a wavelength of 940 nm as a transmitter and a photodiode as a detector at a wavelength of 700-1300 nm and a microcontroller as a minimum system for control. The first stage is measuring uric acid levels with invasive techniques on participants and at the same time measuring voltages with sensors, the results with invasive techniques are correlated with sensor output voltages to obtain non-linear equations in polynomial form, for conversion programs on the microcontroller. The second stage is measuring uric acid levels with invasive techniques and invasive measurements on participants at the same time. Both monitoring results were analyzed by simple ANOVA statistics and calculated SEP and RMSE to determine the accuracy of the prediction equation and its accuracy value.

Abstract

Antosianin merupakan pigmen alami yang menyebabkan warna merah, ungu dan biru. pada bunga, buah, daun, dan biji-bijian. Antosianin termasuk golongan flavonoid berperan sebagai antioksidan yang menangkap radikal bebas yang dapat mencegah penyakit kanker dan tumor. Penelitian ini akan memadukan dua disiplin ilmu yaitu ilmu kimia dan elektro yang akan diaplikasikan pada bidang kesehatan. Pada penelitian ini dirancang sebuah alat yang menggunakan sensor TCS 3200 dan arduino Uno sebagai mikrokontroler. Luaran dari pengukuran ini merupakan data frekuensi warna merah, hijau, dan biru (RGB) yang merupakan warna dasar dari spektrum warna. Prinsip kerja rancangan alat ini pada dasarnya sama dengan spektrofotometer yang mengukur absorbansi panjang gelombang cahaya tertentu pada suatu larutan. Sampel yang digunakan adalah beras merah Maros yang telah di maserasi selama 24 jam dengan variasi pelarut yaitu pelarut aquades, metanol, etanol, aquades-HCl 1%, methanol-HCl 1%, dan etanol-HCl 1%. Hasilnya pengukuran konsentrasi dengan rancangan alat berturut-turut adalah : 0,80 mg/100 g, 0,98 mg/100 g, 0,90 mg/100, 0,82 mg/100 g, 1,02 mg/100 g, dan 0,94 mg/100 g. Hasil pembacaan rancangan alat dibandingkan hasilnya dengan spektroskop UV-VIS. Diharapkan setelah penelitian, rancangan alat ini dapat dijadikan instrument pengukuran awal sebelum analisis colourimetri untuk mengetahui kandungan gizi suatu bahan pangan khususnya antosianin.

Abstract

Mercury is also called “air raksa” or hydrargyrum which is a chemical element with the symbol Hg and belongs to the heavy metal group with a liquid form and silvery color. Mercury is a heavy metal that is harmful to the skin when added to cosmetics, especially creams on the face, even in small concentrations because it is toxic. Identification of Mercury in the laboratory using the thin layer chromatography method with the help of ultra violet light causes medical personnel to be vulnerable to exposure to ultra violet rays which have a negative impact on eye and skin health. The purpose of this research is to design a safety to minimize exposure to ultra violet rays when identify mercury. OV76070 which can reduce direct contact with ultra violet light identifies the present of Mercury in the whitening cream will be carried out using a thin layer chromatography separation method with the help ultra violet 254nm-366nm. With the help of ultra violet lamps 254nm-366nm, and it is hoped that Mercury inspection using the OV7670 camera will be more efficient and accurate. The tool used in this research is the OV7670 camera with a power of 640 – 460 pixels (VGA) to take photo on thin layer chromatography plate, ultra violet lamps 254nm- 366nm. Overall the design of this tool is controlled by the Arduino Uno microcontroller. Image from the OV7670 camera can be monitored at the Liquid Crystal Display in the form of the appearance fluorescence spot indicating the presence of Mercury in the whitening cream sample.
