This research raises the topic of modern technology in the field of rice fields. The problem in this research is determining the fuzzy inference system algorithm for electronic engineering. The prototype was built by Raspberry Pi and python-based to the internet of things. The objective of this research is to design a new model for the rice field monitoring/control system and display every condition based on the internet of things. So that the hypothesis of this research can answer the phenomena that occur in rice fields, including drought problems, maintained plant conditions. The test results showed that irrigation control automatically runs optimally by scheduling, automatic irrigation control of water pH degree value detection analyzed by fuzzy Tsukamoto method at Z=3.5 defuzzification value for low and high irrigation control, and Z value=1.83 for normal irrigation control. Furthermore, the scheduling of spraying liquid fertilizer obtained the results of duration for 60 min in accordance with the needs of fertilizer dose. Lastly, for monitoring data on the website successfully accessed anywhere from the use of hosting servers and domains. Finally, it can be concluded that fuzzy Tsukamoto's algorithm is appropriate to be applied to the modern rice field system.

High economic growth makes the demand for comfortable and safe houses increasingly increase and the most obvious application of technology is technology with automated systems. With this technology, the use of electricity in homes can be monitored remotely. With the aim of optimizing and time efficiency, this research created a control system based on IoT system. The control system with the function of providing security and comfort for the homeowner and the people who live in it, because it can facilitate the work to be faster, effective and efficient. In this regard, in this research the title “Design of Controls and Monitoring of Electricity Loads, and Home Safety with IoT-based Arduino Mega 2560 Systems” is adopted. This application is used as consideration for someone applying the concept of smart homes and the Internet of Things in real life. The results of this research are testing the camera to process the results of taking pictures until the upload process is completed in storage on a computer that is made as a client server is 30 seconds and the entire system works properly and normally.

Voice over Internet Protocols (VoIP) is an IP-based communication technology or commonly known as Internet Protocols (IP). In which, IP is currently widely used for mobile communication activities. However, the main concern in the application of VoIP technology is the system ability to maintain information confidentiality while guaranteeing protection to its primary users. For this reason, it requires to do the addition of Virtual Private Network (VPN) features. Conceptually, it aims to create connection lines in secret by utilizing the internal network structure (intranet) and to be accessed remotely using tunneling protocols in its security system. The purpose of this research is to compare the Quality of Service (QoS) on several tunneling protocols. Moreover, it is conducted to also analyze several security system mechanisms including Delay, Jitter, Throughput and Packet Loss. This analyzation is used for determining the best quality of some of the piloted tunneling security protocols. Furthermore, this work compares several methods of VoIP voice-call-testing in term of Generic Routing Encapsulation with IPSecurity (GRE+IPSec), Internet Protocol in Internet Protocol based Session Initiation Protocol (IPIP+SIP-based), Secure Socket Layer (SSL), and Layer 2 Tunneling Protocol IPSecurity (L2TP+IPSec). Accordingly, the comparative results show the better performance compared to the existing work, which is proven by the ability of the proposed method to provide the VoIP based on ITU-T.G.1010.

A stepper motor is an electro mechanical device that can convert electrical pulses to the axis of movement. The finding problem in the movement of a stepper motor is cannot respond to the clock signal directly because the motor windings require a clock (sequence) in the correct order. If the control signal given is not correct, the motor is not moving according to the specified precision. To answer these problems, it is necessary to move the stepper motor with a clock signal that works in real time. The research method is done by designing and testing the stepper motor movement in full stepp and half step with the direction of Clock Wise (CW) and Counter Clock Wise (CCW) movement. These are simulated by using FPGA Isim and implementation using a stepper motor. The results of several experiments have been carried out the stepper motor movement degree according to the input value entered,responding timely movement, and the direction of movement stepper motor.

The current technological development is SD-WAN (Software-Defined Wide Area Network) which provides highperformance access for users located far from the head office so as to allow faster network connections and has been facilitated automation techniques for branch offices. This research solves the problem of XYZ company because it is known that the company requires network connectivity with a high SLA (Service Level Agreement) and no downtime in the information exchange process. This research hypothesis assumes that using SD-WAN would be ideal and the problems with XYZ company were resolved. The purpose of this research is the implementation of a WAN network using SD-WAN technology against two ISPs on the FortiGate router, as well as testing QoS (Quality of Service) that has been configured using the BGP (Border Gateway Protocol) routing method. This research plan consists of ISP-A using IP-VPN (Internet Protocol-Virtual Private Network) and ISP-B using broadband Internet. The test scenario was carried out using 3 methods, namely Full Service Scenario, Fail Over Scenario-1 when the IP VPN service is down and Fail Over Scenario-2 when the broadband Internet service is down. The final results of the research have obtained "Satisfactory" results for both services, including the average index on ISP-A and ISP-B of 3.7.
