Abstract

The development of technology also affects human health, including body posture due to poor human position when using gadgets, both smartphones, and laptops. This study is design a tool that can measure the elevation of a person's neck angle equipped with electromyography, to help health workers, medical rehabilitation doctors to diagnose and provide treatment to patients with a bent head posture or forward head posture. In this research, an electromyography module is designed which consists of a series of instruments, a pre-amplifier circuit, a high pass filter, a low pass filter, and a dc offset regulator to be converted to digital so that it can be displayed on a laptop. In this study, the tapped muscle was the upper trapezius muscle using disposable electrodes. Meanwhile, to measure the angular elevation, the MPU 6050 sensor is used to measure the movement of the head forward. The frequency of the electromyography signal is 20-500 Hz. For software or display readings from this tool is Delphy. Meanwhile, the microcontroller used for ADC communication is Arduino Uno. From the research, it was found that the neck angle elevation gauge has a 0,597% error rate, for conditioning conducted on respondents, all respondents experienced a decrease in amplitude on the same frequency spectrum in the last ten minutes. Meanwhile, a drastic decrease occurred at the neck angle of 60°. Thus, it can be concluded that the forward position of the head affects the frequency spectrum of the neck muscles.

Abstract

Spectrophotometers generally use a halogen lamp as a light source that passes through a filter (wavelength) according to the material to be analyzed. This study aims to analyze the ability of the LED as a light source on a spectrophotometer. In this study, the authors have determined blood sugar parameters as the test material. So that the determination of the wavelength of the LED as a light source must be adjusted to the specifications of the wavelength in the reagent manual procedure used. In the BAV Greiner Glucose Reagent procedure, the allowable wavelength is between 500 - 570 nm with a cuvette thickness of 1 cm. Measured against the reagent blank by the endpoint method. From this reference, the author uses an LED light source with a wavelength of 530 nm, Epistar brand green. The module in this study consisted of a 530 nm LED lamp as a light source, then a lens was added to focus the light beam from the 530 nm LED. The author also adds a Slit / Aperture or it can be called a small hole so that the light passing through is focused at one point of the circle and is passed to the cuvette. The results of the absorption of light will be received by the light sensor (photoresistor) and the data is processed by Arduino and the results are displayed on the display. From the results of this study, the value ranges error from 1% to 3% when a comparative test is carried out with the Analyticon type Biolyzer100 spectrophotometer with 6 different samples and is repeated 5 times each. From these data, it is found that the LED with a wavelength of 530 nm is effective as a light source for checking blood sugar.

Abstract

One of the equipment in the Turi Health Center laboratory is a Centrifuge. The problem at the Turi Health Center with the centrifuge is that this centrifuge has a large usage load of 8-10 hours per day, without having electromedical personnel. In this Centrifuge, it is often found that the cleanliness of the tools is not good, the placement of the tools is inadequate, the electrical installation network is not standard (Grounding) and the maintenance and maintenance is lacking, there is no regular calibration so there is no certainty of the accuracy of the results obtained. As a result of the impact obtained is a tool that is not suitable for use, the tool is quickly damaged which can harm the diagnosis of patients. Community Service Activities with the implementation team from Poltekkes Kemenkes Surabaya working together as partners in this activity aims to carry out repairs according to Centrifuge standards and provide knowledge and skills about simple maintenance and repairs on Centrifuges Correctly. The first stage in providing solutions to problems faced by the Turi Health Center is to conduct a study through Focus Group Discuss (FGD). The second stage is compiling a user manual. The third stage is the implementation of mentoring and counseling on centrifuge repair using a maintenance and repair manual. And the fourth stage is the implementation of centrifuge repair by providing opportunities for laboratory personnel, Medical and non-medical personnel to be able to independently carry out simple repairs and to know important indicators in the event of damage. The output target of the community service carried out is a simple repair guide book for centrifuge equipment so that later laboratory equipment at the Turi Health Center, especially the Centrifuge, can work according to the Centrifuge Motor Speed Standard.

Abstract

Centrifuge is a laboratory tool used for the process of separating particles of a solution between the filtrate and the substrate through a high-speed centripetal process. The increasing use of Centrifuges at the Turi Lamongan Health Center causes the equipment to be vulnerable to damage. In addition, the lack of handling of these tools is due to limited medical analysts and the absence of electromedical personnel as well as insufficient funds, so that the impact on the health service system at the puskesmas is disrupted. Therefore, it is very important to create a community service program that is carried out in the form of a synergistic collaboration between the Health Polytechnic of the Ministry of Health Surabaya and the Turi Lamongan Health Center which is oriented towards community independence through counseling and assistance, especially in the maintenance of the Centrifuge laboratory. The purpose of this activity is maintenance by testing and calibrating/verifying the motor speed and time on the centrifuge in accordance with the working guidelines. The methodological concept in this activity is to carry out counseling and assistance activities in the maintenance and verification of centrifuge laboratory equipment using a digital tachometer. This activity is an application of previous research on centrifuges and tachometers. The tools used are digital tachometer, savety electrical analyzer, avometer, thermohygrometer, stopwatch and tool set. The materials used are several spare parts, compressors, cleaning tools and cleaning fluids as well as antiseptic fluids. The results obtained from these activities are: 1). The technical specifications of the 4 centrifuge devices are recorded; 2). Identification of damaged centrifuges and those requiring maintenance, namely 2 heavily damaged centrifuges and 2 centrifuges that are still suitable for use; 3). Maintenance of 4 centrifuges; 4). Verification/calibration of 2 centrifuges, namely centrifugal 1 with a relative error of 2.73% in the selection of a motor rotation speed of 2500 rpm is still within the allowable limits (≤10%); for testing the time of 300 seconds, the relative error of 20.57% exceeds the allowable limit, while in centrifuge 2 the results of the relative error in 4 selections of motor rotation speed (rpm) are below 10%, namely 5.92%, respectively 3.82. %, 3.65%, 3.47%. As for the time test, the result of 5.56% is still below the maximum allowable error of 10%. From these results, centrifuge 2 is still in good condition; 5) Implementation of mentoring and counseling for 1 (one) medical laboratory technician (analyst) in performing centrifuge equipment maintenance. The results of this activity can facilitate services at the Turi Public Health Center.
