Abstract

Kalsium sangat dibutuhkan oleh tulang manusia, seldtar 99% kalsium terdapat di dalam jaringan keras yaitu pada tulang dan gigi serta 1% kalsium terdapat pada darah, dan jaringan lunak. Tanpa kalsium yang 1% ini, otot akan mengalami gangguan kontraksi, darah akan sulit membeku, transmisi saraf terganggu. Orang yang kekurangan kandungan kalsium dalam darah disebut Hypocalcemia (rendahnya kadar kalsium pada darah < 8, 5 mg/dl ). Hypocalcemia dapat menyebabkan perasaan kebas pada jari-jari, keram otot, nafsu makan menurun, merasa bingung. oleh karena itu alat ukur kadar kalsium dalam darah ini saya buat. Sistem ini dirancang dengan menggunakan prinsip sperktroskopi yaitu mengukur intensitas cahaya yang melewati sampel dan cahaya yang melewati sampel diterima oleh sensor OPT101 Monolithic Photodiode. Alat ini menggunakan sumber cahaya yang memancarkan cahaya warna merah dan memiliki panjang gelombang 610-680 nm. Sebagai pengolah data digunakan Mikrokontroler AT89S52 dan hasil pengukuran akan ditampilkan oleh LCD. Pada pengujian alat ukur kadar kalsium ini mempunyai tingkat akznasi sebesar 0.994 %. dan presisi alat ini adalah 99.85%

Calcium is absolutely needed by human's bones, approximately 99% of calcium can be found inside of hard tissue, bone, and 1% of calcium can be inside blood and fatty tissue. Without this I% calcium, muscle will get a constraction
disturbance, blood will be difficult to congel, and nerve's transmission will be disturbed. People who has lack of calcium inside the blood is called Hypocalcemia (the lowness of the calcium's level in blood < 8,5 mg/dl). Hypocalcemia can cause paralysis feeling of the fmgers, having cramps in the muscle, takingdown the natural appetite of eating, feeling confusing. Because of that, I decide to make the measuring equipment of calcium in the blood. The system is buit by using the principle of spectroscopy that measure the intensity of light that pass by the sample and it will be received by OPT 10 I Monoholic Photodiode. This equipment use the source of the light that radiatte the red light that have wavelength about 61 0 - 680 nm. As the processor of the data, I use microcontroller A T89S52 and the result of the measuring will be appeared on LCD. This measuring equipment of calcium's level in 0,994 % and precision's level of this equipment is 99.85 %.
