Abstract -- Medical Implant Communications Service (MICS) is one of the emerging technologies in the field of health. Where Implant Devices in this case is the antenna, inserted into the human body between the layers of skin and fat. One application is to monitor the patient's condition such as heart rate monitors, blood pressure and temperature. Working system of implantable antenna is an antenna will transmit signal information to be captured by an RF receiver that are around (External RF Receiver). Microstrip antenna on MICS applications work on the low frequency range is 402-405 MHz. Implants designed antenna is simulated by software based on the Finite Element Method (FEM) and works at a frequency of 403 MHz, using miniaturization techniques, biocompatibility and biomaterials. Antenna will be implanted in the upper arm model. The simulation results with a model of human upper arm, the result of antenna specifications as follows: the physical size of the antenna is 40 mm x 32 mm with a working frequency of 403 MHz, Bandwidth: 17 Mhz, Return Loss: -20.7 dB,VSWR:1.2 Gain: -27.4 dBi, and SAR: 12.7 W// Kg

2021-09-03T16:58:48+00:00

This paper discusses position control design for line follower robot using
Arduino Mega 2560 as a controller, line sensor as a black line detector on the track,
ultrasonic sensor as a detector of distance between the box and the robot with a
distance of 5 cm, and color sensors as red, green and blue color detectors contained
in the box, and the dc motor as driving the right wheel, left wheel and pulley on the
robot. When the robot runs, there is minimal error, and especially the position control
that is suitable for always walking on the black line or being in position 0. The
working principle of the robot is to walk following the black line in the arena to look
for red, green and blue boxes in room 1,2 and 3, then move the box found to the place
provided. PID control is used to maintain the robot's position so that it can follow the
guide line while staying in the center of the robot. From the tuning results, the
constant parameters (Kp, Ki, and Kd) with values (100, 0.1) are obtained to get the
most stable robot position control response during the robot movement towards the
target object of the specified color.

The Community Health Center (PUSKESMAS) has facilities for
weighing and measuring height. This facility is used by the community to determine
their ideal body condition by calculating the Body Mass Index (BMI) which is the
result of calculations from the equipment. However, usually the facilities used to
calculate BMI at PUSKESMAS are still done manually, so it takes time to record
patient history. To facilitate the process of recording and calculating BMI, an
android-based body mass index measuring device was made. This tool can measure
height, weight in an integrated manner, find out the BMI category directly and the
results are directly recorded in the patient database. In testing the equipment made,
an average error of 0.79% was obtained for measuring height, and an average error
of 0.37% was obtained in weighing weight, with success in making BMI decisions
of 100%.

Sistem Monitoring Kadar Gula Darah, Kolestrol dan Asam Urat secara Non Invasive menggunakan Sensor GY-MAX 30100

Measurement of blood sugar, cholesterol and uric acid levels is currently
using the Invasive method. In the invasive method, 3 different tools are needed to
determine the levels of blood sugar, cholesterol and uric acid. This is very ineffective
and inefficient. It is important for the patient to record a history of measuring blood
sugar, cholesterol and uric acid. Currently recording blood sugar results is still using
the writing system on paper. This can cause several problems, including tracing
patient data, not neatly arranged data, and accumulation of stored patient files. From
these problems, a system will be created that can determine blood sugar, cholesterol
and uric acid levels with only one sensor. The method used is Non-Invasive. With
this measurement of blood sugar, cholesterol and uric acid levels can be more
effective in its use. And a Web server will be created that can record patient
measurement history as medical records. With this, patient data search will be faster
and easier to access so that it is more efficient. This research will use the GY Max
30100 sensor which consists of a photodiode to capture light from an infrared LED.
The heart rate pulse values will be converted into blood sugar, cholesterol and uric
acid values. The measurement results will be displayed by the LCD and the data will
be sent to the Web server as a patient's medical record. From testing the GY Max
30100 sensor, blood sugar levels get a measurement error value of 2.86%. Testing
the standard deviation of an average of 2.72% and measurement accuracy of 97.13%.
In measuring cholesterol levels, the measurement error value is 2.86%. Testing the
standard deviation of an average of 4.43% and accuracy of measurement 97.13%. In
measuring uric acid levels, the measurement error value was 11%. Testing the
standard deviation of an average of 0.73% and measurement accuracy of 89%.
Anova test on blood sugar had a sig value of 0.755 (p> 0.05), cholesterol 0.492 (p>
0.05), uric acid 0.217 (p> 0.05). By doing this Anova test, there is no difference
because the sig results on blood sugar, cholesterol and uric acid are> 0.05.

Penggunaan Modul Sensor Sidik Jari (Fingerprint) sebagai verifikasi Ganda untuk Sistem Simulasi Pemilu

The implementation of the General Election is expected to guarantee
the implementation of the political rights of the community in a professional,
honest and integrity manner. However, in reality several frauds were found in the
implementation of the General Election, including Ghost Voters, Multiple Voters
and the problem of the number of lost ballots during the distribution process. For
that we designed an election system that can eliminate the potential for fraud.
This system is the Fingerprint and RFID Sensor Application System in IoT-based
Elections. The RFID sensor is used as the first requirement for prospective voters
to give their voting rights where the detection uses the RC522 sensor, the
fingerprint sensor (Fingerprint) is used as a double verification after the identity
is verified by the RFID sensor as the voter list. that appears on the TFT LCD
screen. The vote count data will be sent in real time to the Web Server by
ESP8266. If the data is not registered, the prospective voter cannot cast their vote
because the TFT LCD does not display a picture of the candidate pair. In addition,
the use of TFT LCD also replaces the use of ballots which are prone to fraud in
their distribution. The results of taking data for 30 times of fingerprint
verification experiments on 3 samples of 10 trials each, the percentage error was
10%.
