[ABSTRAK
Jaminan mutu atas keakuratan alat ukur di bidang kesehatan merupakan kebutuhan yang
mutlak diperlukan pada masa ini. Salah satu alat yang perlu dikalibrasi adalah infusion pump
analyser. Alat ini berfungsi menguji pompa infus yang bekerja pada aliran rendah, yang
digunakan di rumah sakit apakah masih layak pakai atau tidak. Sebagai peralatan uji, infusion
pump analyser harus terkalibrasi untuk menjamin keakuratan hasil pengujiannya. Pada
penelitian ini akan dikembangan sistem kalibrasi yang beroperasi pada laju aliran rendah.
Sistem terdiri dari aktuator linear yang menggerakan siringe dari gelas kaca. Aktuator linear
terdiri dari ulir bola, linear guide way, rangkaian roda gigi yang terhubung ke motor d.c.
Kecepatan motor d.c. dikendalikan oleh FPGA dengan menggunakan metode pulse width
modulation. FPGA juga digunakan untuk membaca keluaran rotary encoder yang terhubung
ke poros roda gigi untuk memantau kecepatan aktuator. Untuk mengkarakterisasi sistem,
pertama osilator FPGA dikalibrasi terhadap universal counter untuk menvalidasi pengukuran
waktunya. Kemudian aktuator dikalibrasi menggunakan kaliper untuk menverifikasi
pergerakan linearnya. Dalam proses ini diamati efek dinamis dari faktor kalibrasi enkoder,
yang membawa kepada penentuan kecepatan intrinsik dari sistem. Dengan menggunakan
kecepatan intrinsik dan faktor alat, maka volume dan laju alir yang dibangkitkan oleh sistem
dapat ditentukan. Selanjutnya sistem diuji secara gravimetri berdasarkan ISO/FDIS 8655-1,
dan didapatkan hasil ketidakpastian pengukuran yang tidak memenuhi syarat. Setelah
melakukan penyelidikan lanjut dengan simulasi pada perhitungan pengukuran, didapatkan
bahwa kapasistas silinder perlu diperbesar agar ketidakpastian pengukuran yang dibutuhkan
dapat dicapai.

ABSTRACT
Quality assurance of the accuracyof measuring instruments in the health industry is
necessary. One of the instruments that need to be calibrated is Infusion pump analyzer. This
instruments is used to test infusion pumps used in hospital at low flow rate. As test
equipment, infusion pump analyzer must be calibrated to ensure the accuracy of test results.
In this study, a low flow rate calibration system is developed. The system consist of linear
actuator to move a glass syringe. The linear actuator consist a linear ball screw, linear guide
way, and gear box connected to d.c. motor. The motor controlled by FPGA using pulse
width modulation method. FPGA also use to read rotary encoder that connected to gearbox
shaft to monitor actuator speed. To characterized the system, first the FPGA oscilator is
calibrated to universal counter to validated the time measurement. Then the actuator is
calibrated using caliper to verify its linear movement. In this porocess a dynamic efect of
encoder meter factor are discovered. This dynamic effect lead to determining intrinsic speed
of the system. The intrinsic speed together with meter factor are used to determine volume
and flowrate generated by the system. The system then tested using gravimetric method base
up on ISO/FDIS 8655-1 and the result of measurement uncertainty is not satisfying. After
further investigation using simulation on measurement calculation, it is found that the
capacity of syringe should be increased to achieve required uncertainty.;Quality assurance of the accuracyof measuring instruments in the health industry is
