Abstract

The Arduino Uno Based Hotplate Magnetic Stirrer Rotational Speed ​​Design has been successfully carried out. The function is to stir and heat one solution with another solution which aims to make a homogeneous solution with the help of a Magnetic stir bar (Stir Bar). The purpose of this design is to know the design of the HotPlate Magnetic Stirrer with 400 Rpm Rotation Speed ​​Settings and to determine the accuracy of the Hotplate Magnetic Stirr rotation speed. The method used is the experimental method. The components in this design are Arduino uno and consist of DC Stepper motor components, motor drivers, 20x4 lcd. The working principle of the design of the hotplate magnetic stirrer based on Arduino Uno. The PLN AC 220V current enters the power supply which converts to a DC voltage of 12V 10A, then Arduino Uno receives a DC voltage of 12V to turn on circuits such as motor drivers that require 12V voltage directly from the power supply, 9V stepper motors, 5V buzzers. Furthermore, the stepper motor will run according to the command set on keyped. To compare the rotational speed settings, use the tachometer calibration tool. The test results show the Rotational Speed ​​of the Arduino Uno-Based Hotpate Magnetic Stirrer, the rpm rotation speed is in accordance with the settings and the results obtained are 10% tolerance. The results of measuring the voltage on the power supply.

Abstract

Abstract. Uv-Vis Spectrophotometer is one of the instruments in the hospital located in the clinical laboratory where its management is under the responsibility of the Electromedical Technician. The medical device technology development has led to adjustments and developments in managing the Uv-Vis spectrophotometer. The purpose of this service activity is to provide Inspection Preventive Maintainance (IPM) training for Uv-Vis spectrophotometer equipment and share developments in Uv-Vis spectrophotometer technology with electromedical technicians. With this, hospitals can provide complete services to the community. The training was held on March 26, 2022, using the Zoom Meeting media and was attended by 401 participants from all over Indonesia. Participants were given a pretest and posttest to determine the level of participants abilities with this training. Before the training, the ability of the participants was 60.30% while after the training the ability of the participants was 78.55% so there was an increase in the ability of the participants by 18.25%. The average level of participant satisfaction with this training activity is 85.54%, which is in the very satisfactory category Abstrak. Spektrofotometer Uv-Vis merupakan salah satu alat di rumah sakit yang berada pada laboratorium klinik dimana pengelolaannya di bawah tanggung jawab Teknisi Elektromedis. Perkembangan teknologi alat kesehatan menyebabkan adanya penyesuaian dan perkembangan terhadap pengelolaan alat spektrofotometer Uv-Vis. Tujuan dari kegiatan pengabdian ini adalah memberikan pelatihan Inspection Preventive Maintainance (IPM) peralatan spektrofotometer Uv-Vis dan sharing perkembangan teknologi spektrofotometer Uv-Vis kepada teknisi elektromedis. Dengan hal itu, rumah sakit dapat memberikan pelayanan yang paripurna kepada masyarakat. Pelatihan dilaksanakan pada tanggal 26 maret 2022 menggunakan media Zoom Meeting dan diikuti oleh 401 peserta dari seluruh Indonesia. Peserta diberikan pretest dan postest unutk mengetahui tingkat kemampuan peserta dengan adanya pelatihan ini. Sebelum pelatihan kemampuan peserta sebesar 60,30% sedangkan setelah pelatihan kemampuan peserta sebesar 78,55% sehingga terjadi peningkatan kemampuan peserta sebesar 18,25%. Adapun rata-rata tingkat kepuasan peserta terhadap kegiatan pelatihan ini adalah 85,54% berada pada kategori sangat memuaskan.
