Abstract

Health equipment is a supporting tool for medical service facilities. Room temperature is also very important in the placement of medical devices so that there are no errors in reading the equipment or damage to medical devices can occur. Calibration is an activity to determine the conventional truth of the value of the indication of measuring instruments and measuring materials by comparing them to traceable measuring standards to national and international standards for units of measure and/or international and certified reference materials. The method used in conducting electrical safety test analysis and calibration on the centrifuge is ECRI, IEC 60601-2. The results of environmental measurements at temperature and humidity meet the requirements with a measured room temperature of 23°C and room humidity of 57.1%, the results of the electrical safety test measurement are declared safe and measured. Protective earth resistance is 0.432mΩ, equipment leakage current is 0.1µA and insulation resistance is 11.1MΩ , the results of the rotational speed accuracy measurement meet the tolerance limits of each value, for setting 2000RPM, 2500RPM, 3000RPM, 3500RPM, 4000RPM there is a deviation of 14.8 with an uncertainty value of 7.0 RPM, the results of the time accuracy measurement meet the tolerance limit with a setting value of 5 minutes (300 seconds) there is a deviation of 1.6 seconds with an uncertainty value of 2.55 seconds, for a full automatic Centrifuge with type HC-16D with Serial No. 2H01018 declared fit for use because it meets the tolerance limit.

Abstract

Hotplate magnetic stirrer is a tool used to homogenize and heat a solution, this tool is used in microbiology, chemistry and pharmaceutical laboratories to homogenize and heat a solution. The main component of the hotplate magnetic stirrer is the stepper motor which functions to rotate the sample and heat it using a heater at a predetermined speed and time. The hotplate magnetic stirrer that the author made uses an Arduino uno At mega 328p microcontroller, a motor driver, a 20x4 LCD, a buzzer and a keypad. the motor driver is used to adjust the motor speed according to the user's wishes, the LCD functions to display the motor speed and timer, the buzzer will sound when the magnetic stirrer hotplate is turned on and when the keypad is pressed, the loadcall functions as a sensor used to detect the pressure that is placed on the plate , the HX711 module functions to convert measured changes in resistance changes and convert them into voltage quantities through existing circuits, keypads as speed and timer inputs. When the speed has been reached, the motor driver will work to control the motor to keep it according to the desired speed.

Abstract

Pada masa pandemi pembelajaran tatap muka ditiadakan sementara. Dan untuk materi pembelajaran pada alat roller mixer ini menggunakan aplikasi open source Proteus, dimana aplikasi ini bisa membuat perancangan alat roller mixer dan mahasiswa masi bisa memahami bagaimana proses pembuatan alat roller mixer. adanya peningkatan pembelajaran dengan memanfaatkan pembelajaran berbasis media interaktif pada alat roller mixer dengan simulasi pada mata kuliah peralatan laboraturium klinik pada mahasiswa Teknik Elektromedis Universitas Sari Mutiara, dengan meningkatnya nilai yang semula nilai mencapai 55 pada siklus 1 mencapai 63 dan setelah dilakkukan perbaikan dan dilanjut pada siklus 2 mendapatkan nilai 72.
