Abstract

The process of giving directional information to assist airplanes in making an accurate landing at the airport of destination is known as aviation navigation. The VHF Omnidirectional Range is a crucial navigation tool for guiding planes to the airport (VOR). Since it costs a lot of money to learn how to fly an airplane, a VOR simulator was developed that can mimic the movement of an aircraft passing through the VOR. The simulation that was produced is a prototype that sends and receives signals to the aircraft utilizing an antenna and microcontroller as supporting hardware. The VOR/DME flight navigation system is constructed in this study using mathematical modeling; a formulation representing the essential features of the system is expressed as a set of connected variables. The ESP32 module that powers the system serves as a DME by sending out Bluetooth radio signals. where one ESP32 module serves as a DME object (moving DME) and three ESP32 modules serve as DME stations (ground DME). Information on the distance between the DME station and the DME object will be communicated using the MQTT protocol, and this data will be processed using the trilateration method to predict the location and movement of the DME object. The measurement accuracy at DME station 1, DME station 2, and DME station 3 are 99.52%, 99.92%, and 99.98% respectively. The enhanced capabilities to estimate the position of objects observed from different directions or omni-directionally on a two-dimensional scale are made possible by the performance results of combining the performance of three ESP32 devices as Distance Measurement Equipment (DME).

Abstract

Gout or gout arthritis is a disease caused by the accumulation of monosodium uric crystals in the body. Uric acid is the result of the final metabolism of purines, which is a component of nucleic acids found in the body's cell nucleus. Increased uric acid can cause disturbances in the human body such as feelings of pain. The standard system used to measure uric acid levels in the blood, in general, is an invasive system that uses blood samples and is performed in clinics, health centers, and hospitals at a high cost. This research aims to develop a non-invasive system measuring gout using Near Infrared (NIR) sensor with 940 nm LED and Photodiode as a detector at a wavelength range of 600-1300 nm. The method of developing this tool begins with the stages, conducting a literature study resulting in tool design and tool making as well as tool validation by comparing invasive and non-invasive techniques. The results of this study produce a simple gout monitoring tool with an error value of 4% and low cost and easy to use. Analysis of the results of the tests using analysis of variance P-value> 0.05 and the t-test P (T <= t) 0.45> ? shows that the tool designed can be used to monitor gout.

Abstract

Blood glucose is a very important element in the human body, but if it is deficient or excessive, it can cause chronic disease that can lead to death. To prevent this, it is necessary to monitor cholesterol and blood glucose levels regularly, at this time the tool for measuring blood glucose levels is still an invasive method by taking a blood sample at the fingertip by injuring it. This study aims to develop a non-invasive blood glucose measuring device using a Photoacoustic Spectroscopy sensor in the range of values from a laser pulse source (? = 650 nm) which can detect glucose signals in the blood. The method of developing this research is by designing a non-invasive measuring instrument and measuring blood glucose levels in male and female participants to create a linearity equation between blood glucose levels and the output voltage from the sensor, then mathematically obtained a polynominal equation to convert the voltage to values. blood glucose level. Validation of measuring instruments designed by comparing invasive measuring instruments as a reference, using the Clarke EGA to determine accuracy based on the classification of values of blood glucose and blood cholesterol levels based on reference. The results of the Clarke EGA analysis show that all measurement data is in Zone A so that the measuring instrument with a photoacoustic sensor can be accepted.

Abstract

Gout disease or commonly known as gout arthritis is a disease caused by the accumulation of monosodium urate crystals in the body. Monitoring blood uric acid levels is currently still using invasive techniques by taking blood samples to be included in the test strip, this invasive technique measurement requires money and time to come to health clinics so that many people cannot monitor blood uric acid levels on a regular basis. This study aims to develop a measuring instrument for monitoring blood uric acid levels using sensors by utilizing the absorption and reflectance of infrared rays so that gout sufferers and other individuals can monitor blood uric acid levels regularly and are easy to use. The method of developing non-invasive techniques focuses on monitoring blood uric acid levels using a NIR sensor with an IR LED with a wavelength of 940 nm as a transmitter and a photodiode as a detector at a wavelength of 700-1300 nm and a microcontroller as a minimum system for control. The first stage is measuring uric acid levels with invasive techniques on participants and at the same time measuring voltages with sensors, the results with invasive techniques are correlated with sensor output voltages to obtain non-linear equations in polynomial form, for conversion programs on the microcontroller. The second stage is measuring uric acid levels with invasive techniques and invasive measurements on participants at the same time. Both monitoring results were analyzed by simple ANOVA statistics and calculated SEP and RMSE to determine the accuracy of the prediction equation and its accuracy value.

Abstract

The terms granule and granulation are familiar terms in the pharmaceutical field. Granulation activities cannot be separated from the weighing process. Granules are lumps of smaller particles with an uneven shape that become like a single larger particle. In general, pharmacists still use analytical balances to weigh. Weighing using an analytical balance tends to be inefficient because it takes a long time. In this study, a weighing system was designed with the function of automatically weighing drug granules and equipped with a container to accommodate the granules so that there is no need to manually load the granules onto the scales. The purpose of designing this tool is to make it easier for pharmacists to weigh drugs during granulation and make drug preparations. The design of this tool uses a load cell sensor, a servo motor to open and close the flow rate of drug granules from the container automatically, and a DC motor to help accelerate the flow rate of drug granules to the container, which is detected by the load cell sensor. Implementation of the results of this study can be used by laboratory personnel to weigh chemical substances in the form of powders and pharmacists to make it easier to weigh medicine granules. The results of the readings from the automatic weighing device are compared with the results from digital scales, which show an average deviation of 40%.

Abstract

 Infus disebut juga dengan Intravenous Fluid Drops (IVFD), diartikan sebagai jalur masuk cairan melalui pembuluh vena. namun pada kenyataannya cairan infus meiliki jenis yang macam – macam, sehingga tidak serta merta dikatan bahwa infus adalah makanan pengganti bagi orang sakit.Alat infus yang khususnya sering digunakan pada pasien ruang rawat inap masih menggunakan sistem pemantauan secara manual dan bisa saja perawat atau keluarga pasien yang mengawasi pasien tidak memperhatikan tetesan cairan infus karna sedang tidur, terutama apabila pada jam–jam istirahat pada malam hari alat infus ini terkadang tidak terpantau jika suatu waktu alat infus ini berhenti menetes. Penelitian ini mengajukan suatu gagasan untuk medeteksi   tetesan infus dengan sistem informasi melalui SMS yang akan dikirim ke perawat yang berada di ruangan perawat maupun di ruangan lainnya, perawat dapat mengetahui lebih cepat kondisi cairan infus setiap pasien di ruangan perawatan. Metodologi  penelitian ini melakukan study literatur, dan merancang  alat yang dapat bekerja secara automatis dengan menggunakan modul GSM. Serta sistem kontrol menggunakan  Arduino Uno. Hasil yang diperoleh setelah  dilakukan pengujian waktu pengiriman SMS ke perawat dengan kesalahan 3% dari waktu pengiriman sms dari modul gsm yang diprogram pada SIM800L ke handpone operator selama 8 detik. Sehingga alat ini layak untuk digunakan pada ruang, ICU.dan ruangan Perawatan lainnya. Kata kunci : Mikrokontroler arduino uno, sensor photodiode, dan SMS.
