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

Coffee is one of the most popular drinks in Indonesia because of its taste and aroma. Coffee in its presentation has different types which are determined by the coffee beans maturity level during roasting, including light roast, medium roast and dark roast. Each of the three types of roasting profiles has a different level of moisture in the beans. The use of a roaster machine to determine the coffee beans maturity level often uses temperature and roasting time settings. Knowing the capacitance value in determining the roasting l evel is expected to increase the accuracy of the roasting level. In this study, a capacitor sensor consisting of two parallel copper plates was designed to determine the roasted coffee beans maturity level. The frequency value and color sensor in the system were used to determine the basic value of the classification of Kawi coffee beans maturity level in the fuzzy system. Based on the results, namely at a parallel cap acitor sensor distance of 2 cm, the oscilloscope readings of dark maturity have a frequency range between 201KHz - 213KHz, medium in the range 179KHz - 206KHz and light 178KHz - 200KHz. Meanwhile, the Arduino frequency counter readings at the dark maturity level in range of 204KHz - 234KHz, medium in range of 210KHz - 227KHz and light at 205KHz - 223KHz.

Abstract

A room with too humid conditions can cause mold and bacteria to multiply quickly. The humidity level of the room can be influenced by several factors such as the temperature level and the intensity of light entering the room. Even so, the use of lighting as a sterilizer is currently still lacking in reducing the level of humidity in the room. For this reason, it is necessary to develop technology in the form of a control system for the use of led and ultraviolet lamps in the study room by utilizing the IoT system, so that it can turn on the lights and utilize electrical energy. In this study, the Internet of Things system was applied as a control for Web cameras, Gyml 8511, DHT11, and BH1750 sensors. Data from the sensor will be sent from Arduino uno to a local server, namely raspberry pi 4 using NRF24L01. The communication system between nodes is designed with a mesh topology that can determine the fastest route in the process of sending information. The result of this research is monitoring on the web display that displays the condition of the class and the condition of the lights. From the experimental results, it is found that the mesh communication system can work well.

Abstract

Paper is one type of archive that is stored in the Archives Building. Maintenance of paper type archives needs to be considered to avoid mold growth and discoloration due to cigarette smoke. Therefore, a telecontrolling device is needed that can maintain a stable air humidity at 30% - 55% and a temperature of 15 °C - 22 °C. However, devices with a frequency of 2.4 GHz should not be used simultaneously in the same area because it will cause interference that can reduce performance. In this study, a temperature tele controlling system and smoke detection in the archive warehouse were made using hybrid visible light communication technology to improve data transmission performance. The system consists of 1 transmitter node connected to DHT 22, MQ 2, LED laser and WiFi network, as well as 2 receiver nodes to control the fan and water pump. The data from the receiver will be passed through the photodiode and then processed by the microcontroller. If the temperature value reaches the threshold, the receiver node will send a command so that the fan will turn on automatically, then if the smoke value reaches the threshold, the water pump will turn on automatically. The temperature and smoke values ??can be monitored in real time through the android application. The test results show that the use of hybrid visible light communication technology in the tele controlling system makes the delivery performance better.
