Abstract

A humanoid robot is a robot that has a human-like shape, which has a body and head, two arms and two legs that allow it to move and interact with the environment created by humans [1]. The humanoid soccer robot system currently used still uses the Robot Operating System (ROS) system, which is basically in the system without any encryption or data security every time communication is made by sending and requesting or what is commonly called Publish and Subscribe. In order to develop the humanoid soccer robot, this research is designed for "Implementation of Advanced Encryption Standard (AES-128) Cipher Block Chaining (CBC) Mode as Communication Security for Humanoid Robot Movement KRSBI". Which is designed to operate in low quality connectivity, with network bandwidth that secures every node running on the ROS which includes features for subscribing to topics and also publishing topics. Then with the addition of cryptography can keep data or messages safe when sent, from sender to receiver without experiencing interference from third parties. According to Bruce Scheiner in his book "Applied Cryptography", cryptography is the science and art of keeping messages secure. [2] So all communications are encrypted using Secure Sockets Layer (SSL), or more specifically Transport Layer Security (TLS).

Abstract

Physical exercise is an activity carried out to maintain a healthy body condition. Health is the most important part of all activities carried out by humans by paying attention to vital signs such as body temperature, heart rate, and others on a regular basis. Regular physical exercise for a long time, which is about 30 minutes, can cause changes in bodily functions. The acute effect of excessive physical exercise results in an increase in heart rate and body temperature. This study is designed to control and monitor body temperature as well as other vital signs of health during exercise, and to avoid excessive physical exercise. Research that has been conducted previously obtained the results of values before exercise for body temperature using infrared and ds18b20 which have a range between 34.550C - 36.090C and 35.060C - 36.190C, values for skin moisture range from 47% and heart rates between 94 Bpm - 118 Bpm. Meanwhile, during the exercise, the body temperature is between 36.380C - 36.810C, skin moisture between 47% - 15%, and a heart rate between 105 Bpm - 95 Bpm with a value of delay between 0.034897000s - 0.037563000 s during the live streaming. Based on this research, it can be concluded that the fan can turn on automatically and successfully reduce the user's body temperature gradually with a temperature range between 35,000C - 36.80C.

Abstract

The toll ticket payment mechanism still uses e-toll cards by attaching e-toll cards to the reader at the toll gate. This has several drawbacks, including the driver having difficulty sticking the cards. At present, a device has emerged to access the toll road without attaching a card known as the OBU. However, this device has a pretty expensive price. Therefore, an access system in and out of toll roads is made without using a card. With this system, users only need to register license plates in a database and there are applications that will also be used for payment, and as trip monitoring. By using ultrasonic sensors and image processing methods, vehicle license plates that will enter the toll road can be detected. The test results are known to distance of the camera to the number plate to read correctly as far as 2 - 3 meter and when the distance of the camera to the number plate as far as 4 m, shows the wrong reading of the license plate. Ultrasonic sensor testing showed no failure in ten attempts. Ultrasonic sensors are used to detect the presence of objects vehicles when vehicles enter or exit the toll road

Abstract

The need for water in each land varies depending on the area and conditions of the land. In addition, the technology is still done manually. We need a lot of time to irrigate the plants therefore it is not effective. Efforts must be made to optimize water management, such as on-time, on quantity, and on target, as well as covering a large area. This research proposes an android-based automatic floodgate telecontrolling system by utilizing a Soil Moisture sensor and an android application. Relays are used as opening and closing sluices. The results of the relay status when on or off and the humidity value will enter the application and can be monitored in real-time. The test results show that the Soil Moisture  Sensor can detect Soil Moisture with an average error of 0.362%. The control and monitoring system through the application using Android is in accordance with the plan with an average delay for ON / OFF status and a humidity value of 0.487295s.

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 process of sending information there is always interference or noise, the nature of noise cannot be eliminated but can be minimized. In this study, the author uses an IIR Digital Filter because the IIR filter has an impulse of infinite duration so that it can be matched with an analog filter which also has an impulse response of infinite duration. 1 and chebyshev type 2 on MATLAB. MATLAB code is used to create a filter design program according to the specifications that have been made. MATLAB Simulink is used to create a block filter design to be implemented on the Raspberry Pi. Raspberry pi is used as a device to process the filter. The results of running MATLAB code and also Simulink are compared to see if the implementation results are the same as the program results. The types of filters that are good for use in IIR digital filters are Butterworth filters and Chebyshev 2 filters because there is no ripple in the passband. The type of filter that is not good for use in digital IIR filters is the Chebyshev 1 filter. The effect of ripple changes on the order value is that the smaller the ripple value, the larger the resulting order value. The effect of changing the stopband attenuation is that the more the stopband attenuation, the smaller the resulting order.

Abstract

People want a vehicle that is ready to use without having to wait for long or in the sense that the performance of an activity can run efficiently. With a remote control that can control the vehicle remotely, activities in setup mode will be more efficient. In general, remote control is used in motorized vehicles using Infra-red or Bluetooth communication with communication distance 60meters. So we need LoRa module that has longer beam range. The purpose of research is to design remote control and receiver that can control the vehicle such as opening vehicle door lock,  activating the AC, to the starter mode on the car contact with a wider range of sending and receiving information. The results of research indicate that LoRa module has received signal strength value (RSSI) of -65dBm when LOS (line of sight) at distance 10meters and RSSI of -66dBm at non-LOS (non-line of sight) at the same distance. SNR of 9.25dB when LOS and SNR of 6.0dB when non-LOS at distance 10meters. The research results of sending and receiving remote control data have a maximum distance when non-LOS with obstacles 5mm thick glass and 20 cars is 100 meters with a received signal strength of -112dBm. It can be concluded that for non-LOS connectivity between the LoRa SX1278 has an effectiveness distance at 50meters with an RSSI value of -99dBm and an SNR of 0.25dB, for a LOS condition it has an effectiveness at distance 50meters with RSSI value of -96dBm and SNR of 9dB.
