UAV (Unmanned Aerial Vehicle) is the unmanned aircraft which is controlled by Remote Control (RC) when flying. The operation of the UAV needs to be regulated to maintain air traffic security, one of which is by taking over the UAV. This study discussed the FSK modulation and demodulation mechanism in the process of taking over the UAV with HackRF One. The transfer mechanism of the UAV that done is to look for the RC frequency, channels, record the RC signals, determine the period and frequency carriers, and modelling the modulation and demodulation of FSK with Simulink. One parameter that is set in the process of this mechanism is to change the value of the different carrier frequencies. Then, the data obtained from the signal sent modulated results are the same as when the demodulated signal. Of T0= 79 μsandT1= 70 μs, so that fc0= 12658,22 Hz and fc1= 14285,71 Hz. To determine the size of the signal quality, it is necessary to determine the Bit Error Rate (BER) value. In this research, the obtained the BER values depend on the change of the energy value of Bit per Noise (Eb / No). When the Eb/No value is 10 (dB), then the BER is 0.038. Moreover, when the Eb/No value are 8 and 6 (dB), then the BER will be 0.078 and 0.23 respectively. It can be concluded that the greater Eb/No, the lower of BER.Keywords: UAV, Remote Control (RC), FSK Modulation, Simulink, HackRF One

Three dimensional animation is one of the technologies that developed nowadays. Using three-dimensional animation, we can describe something we want to convey to others and the wider community. Green screen is a special effect used to combine two images. This technique is also known as Chroma Key, color-keying, Color Separation Overlay (CSO) or blue screen. Chroma Key or blue screen / green screen, also called color keying, color separation overlay is a technique used in film and television, to change the background color with another background image using the Chroma Key technique, background of objects recorded with a video camera can be replaced with other desired backgrounds. Here the author uses 3D Animation to change the background of green screen because it is interesting and will be easily remembered by the public.Keywords: 3D animation, Green screen, Chroma Key

Security is an important aspect in computer network operations. To support, computer network security, various security methods have been developed, both in application level security, such as Pretty Good Privacy (PGP), end-system level security, such as Socket Secure Layer (SSL), direct-link level security such as Multi Protocol Level Switching (MPLS) and IP layer security such as IP Security (IPSec). IPSec is a collection of protocols for securing networks through authentication and IP packet encryption. On the other hand, Internet Protocol Version 4 (IPv4) as a network protocol is not safe enough and is no longer able to serve the needs of new IP addresses around the world, and will soon be replaced with IPv6. Therefore, it is necessary to examine various security methods that can be developed in IPv6. In this study, the author will analyze the Multi-Layer IPSec in securing IPv6 networks.Keywords: IPv6, IPSec, Multi-Layer IPSec

Waste is one of the problems that often arise in every major city. Poor waste management is the main cause of the problem. If it is not dumped in a certain area, waste management generally only reaches the combustion stage. This management makes waste into a pile that is endless and has no value. In the current era of Industrial Revolution 4.0, waste management can be customized so that waste becomes more useful and worth selling. This research was conducted in terms of building a digital startup that focuses on waste management. For the MVP (Minimum Viable Product) feature in this research, the Channel (media communication between users and digital startup) used in the form of Landing Page. The waste to be managed is grouped into organic waste and inorganic waste. Organic waste is managed using a composter media to produce fertilizers, and inorganic waste is managed so as to produce recycled goods that have a selling value. The focus of this research is digital based waste management in one of the big cities in Indonesia, Medan City. Research on Waste Management in the Era of Industrial Revolution 4.0 Based on Digital Startup is done so that people in Indonesia, especially in Medan City are aware of good waste management, so that one of the problems that often arise due to waste can be minimized. Digital startup in terms of waste management was established with the name of Angkut Sampah.Keywords: Waste Management, Industrial Revolution 4.0, Digital Startup, Angkut Sampah

The process of sterilizing palm fruit with a capacity of thousands of kilograms is carried out using saturated steam with a temperature of ± 132º C which is a process that greatly affects the quality of the palm oil produced. The amount of fruit and the amount of pressure are the parameters that affect the duration of the boiling process, thus, the exact calculation of boiling time is needed so that the quality produced will be optimal. The Fuzzy Logic method which has been widely developed in the field of control systems can be used as an alternative in designing a control system capable of carrying out the sterilization process by considering the amount of fruit and the amount of pressure used in the boiling process so that it can predict the length of the boiling process that will run based on the rules that have been implanted. Fuzzy logic method in the control system can be simulated using ladder diagrams and tested before the system designed is implanted with the control system device used, which is Programmable Logic Control (PLC). Applying the Fuzzy logic method that is embedded in the PLC, the boiling process can be run more optimally by providing parameters of the number of pieces and the amount of pressure as input, then the control system can predict the length of time the boiling process will be run.Keywords: Fuzzy Logic, Ladder Diagram, PLC, Sterilization

Automatic doors are generally developed by RFID cards or use cards with barcode labels. According to [1] the weakness of RFID is that the reading distance of the RFID Card is around 5 cm. According to [2] cards with barcode labels still have weaknesses such as barcode labels that are scratched, so that it cannot be identified. From RFID and barcode labels weaknesses, then an automatic door was designed using Arduino Uno with the Bluetooth module and controlled using an application on a smartphone instead of a card. Automatic doors with Android-based smartphone locks have several advantages, namely the ease, practically and relative security of losing keys. This technology is not yet commonly used by the people of Indonesia and is expected to be an alternative going forward as a solution in applying the concept of housing with smart technology. The purpose of this study is to design an automatic door using a Bluetooth signal connection and analyze the signal strength connected with a smartphone. The Bluetooth module used is the HC-05 module which operates at 2.4GHz frequency. According to [7] to produce a good Bluetooth connection, it is necessary to control and filter noise. The method in this research is to design an automatic door and then analyze the signal strength and signal range from the smartphone to the door. Smart home-based door systems with Android smartphone door locks can be used normally up to 9 meters and are considered sufficient for the size of a house in general.Keywords: automatic door, RFID card, Arduino Uno, bluetooth, smart home
