Abstract

In this study we can determine the effect of temperature on wavelength and frequency on fiber optic media by using a splitter by looking at the measured wavelengths when the optical fiber is heated using an aluminum intermediate as a heat sensor. With temperatures to be used ranging from 270?C to 400?C. The measurement was carried out using an Optical Spectrum Analyzer (OSA) device. From the temperature variations given, the conclusion is that the greater the temperature given, the farther the wavelength shift and the smaller the resulting frequency. The wavelength produced on the fiber optic splitter cable 1 to the fiber optic splitter cable 4 has almost the same wavelength value starting from a temperature of 270 ° C- 400 ° C. the difference occurs when the cable before the splitter and after the seplitter. The validity level in each splitter has a different persesn value such as the splitter has a validity value of 99.80%, splitter 2 has a validity of 99.72%, Splitter 3 has a validity of 99.72% and splitter 4 has a validity of 99.70%

Abstract

The purpose of this study was to design a capacitive sensor system to investigate the effect of Dampit coffee roasting on the relative permeability of coffee. Where this relative permeability value will be used as a reference to determine the level of Dampit coffee roasting. The method used is to design an oscillator circuit, where a capacitive sensor is used as a component of the oscillator. The capacitive sensor is composed of 2 square copper plates with a side length of 10 cm. The distance between the copper plates varies from 2 cm, 3 cm, 4 cm, and 5 cm. The type of oscillator used in this study is an RC oscillator with 4049 CMOS IC. The results of this study indicate that dark roasted coffee has the highest frequency, the largest capacitor value, and the smallest permeability value. Increasing the distance between the copper plates increases the output frequency of the capacitive sensor. The average relative permeativity of dark coffee is 10.92; medium coffee of 12.45; and light coffee of 14.4.

Abstract

Stroke Transient Ischemic Attack (TIA ) adalah kondisi stroke ringan. Stroke ringan diakibatkan oleh berkurangnya suplai darah menuju otak. Kelumpuhan disebabkan oleh kurangnya aliran darah ke otak, sehingga sisi tubuh akan mengalami kelumpuhan terutama pada siku dan lutut. Fisioterapi pada pasien pasca stroke ringan dilakukan dengan metode terapi gerakan antara lain seperti penggunaan alat bantu fisioterapi pasien pasca stroke menggunakan sensor MPU6050 melalui media transmisi Bluetooth. Sistem rancangan ini membantu latihan pada pasien berbentuk sensor MPU6050 yang digunakan untuk mendeteksi sudut serta banyaknya gerakan rehabilitasi pasien pasca stroke. Sensor gyroscope menghasilkan deteksi sudut pada siku sebesar 150 dan sudut pada lutut sebesar 135 . Data yang didapatkan diproses oleh arduino nano menggunakan metode I2C. Penelitian ini bertujuan untuk merancang alat bantu fisioterapi pasien pasca stroke berbasis mikrokontroler guna memperoleh hasil yang maksimal karena bentuk alat ini yang portable. Stroke Transient Ischemic Attack (TIA) is a mild stroke condition that can be caused by reduced blood supply to the brain due to blocked blood vessels. Lack of blood flow to the brain can cause paralysis, usually only on one side of the body such as the elbows and knees. Physiotherapy in post-stroke patients is carried out using movement therapy methods, including elbow and knee flexion. Currently, patients come to the therapist or vice versa to perform therapeutic movements, so a telemonitoring system for post-stroke patient physiotherapy tools is made using the MPU6050 sensor which is connected to ESP 232 and the internet network and can be monitored by therapists and clinic admins where the therapy is done. This system helps monitor elbow and knew flexion exercises using the MPU6050 sensor which is used to detect the angle and number of rehabilitation movements of post-stroke patients. . From the results of testing the accuracy of this sensor is able to detect the angle of elbow movement from 00-1500 and knee flexion angle of 00-1350 by 99%.The telemonitoring application for physiotherapy tools for post-stroke patients based on Android is equipped with a therapist menu so that the number of movements and the average angle of movement of the knees and elbows can be monitored by the therapist, this tool can also be used anywhere and anytime due to the portable form of this tool.
