<![CDATA[The Social Force Model (SFM) is a popular navigation technique for mobile robots that is primarily used to simulate pedestrian movement. The SFM method's drawback is that several parameter values, such as gain, k, and impact range, σ, must be determined manually. The reaction of the SFM is frequently inappropriate for certain environmental circumstances as a result of this manual determination. In this paper, we propose employing the Fuzzy Inference System (FIS), whose rules are optimized using a Genetic Algorithm (GA) to manage the value of the gain, k, parameter adaptive. The relative distance, d, and relative angle, α, concerning the robot's obstacle are the inputs for the FIS. The test results using a 3-D realistic CoppeliaSim demonstrated that the learning outcomes of FIS rules could provide adaptive parameter values suitable for each environmental circumstance, allowing the robot to travel smoothly is represented using the robot’s heading deviation which decreasing by and reaching the goal 1.6 sec faster from the starting point to the goal, compared to the SFM with the fixed parameter value. So that the proposed method is more effective and promising when deploying on the real robot implementation.]]>

<![CDATA[A miniature sorting of material quality has been made, aided by a prototype of the controller system based on the Mitsubishi FX1N-24MR Programmable Logic Controller (PLC). A number of stages include the manufacture of the conveyor system unit, the electrical system, PLC programming, and performance measurement. The conveyor unit assembling was processed by installing the conveyor belt, dc motor, pneumatic cylinder, solenoid valve, and sensors. The electrical system is an integration of the Mitsubishi FX1N-24MR PLC, switched-mode power supply, miniature circuit breaker (MCB), dc voltage regulator circuit, relays, digital counters, pushbuttons, and selector switches arranged in a 20 x 30 x 15 cm panel box. Mitsubishi PLC system programming is based on algorithmic determination and ladder diagram arrangement assisted by GX Developer (GX Work). Performance measurement in the form of pulse readings is carried out by setting and manufacturing ladder counters and shift registers to count the number of pulses for each material and the accuracy of sorting when the material is detected simultaneously. The system performance is indicated by pulse reading accuracy and sorting timing accuracy. The reading of the pulse from the proximity switch affects the counter calculation to activate the pneumatic cylinder unit in sorting. Sorting for material-A takes 11 pulses, while for material-B, it takes 19 pulses. The synchronization measurement functions when an error occurs in the system in order to maintain the input received is the same as the output in the PLC-based control system. ]]>

<![CDATA[The research discusses about the energy saving techniques in the design of data logger devices based on AVR microcontroller for monitoring parameters of the air temperature and sunlight intensity in the visible light spectrum. These energy reduction techniques include hardware aspects such as the use of the minimum system, peripherals power supply control and software such as sleep-mode. When the intensity of sun light increases, the interrupt pin will activate the system, otherwise the system is in a state of sleep-mode. The electrical energy consumption of the data logger is continuously observed and recorded on an external memory (SD card) in real-time as so the 24 hours energy consumption can be known and the long-term-used energy can be predicted. Based on the results of measurements and calculations it is known that it takes energy of 8.23 Wh to turn the data logger for 24hours. With this reduction technique, the data logger energy consumption can be reduced by 68.5%.Keywords: data logger, energy saving, sun, sleep mode, interrupt]]>

<![CDATA[Occupational Safety and Health (K3) is an important requirement needed in mining. This is because activities in mining have great risks and are associated with unpredictable natural conditions. One of them is the leakage of hazardous gas at the mine site caused by mining activities. This article proposes a wheeled robot to detect carbon monoxide gas and methane gas based on the Internet of Things (IoT) using Finite State Machine (FSM) and Fuzzy Logic. The finite state machine (FSM) in this study is used as a control of the robot’s movement, while fuzzy logic is used as a safety classification of the readable state of dangerous gases. The results showed that the system was capable of detecting gas and the information is successfully sent to a web server. In addition, the use of lidar can detect obstacles around the robot. ]]>

<![CDATA[This paper proposes an authentication mechanism on the MQ Telemetry Transport (MQTT) protocol. The exchange of data in the IoT system became an important activity. The MQTT protocol is a fast and lightweight communication protocol for IoT. One of the problems with the MQTT protocol is that there is no security mechanism in the initial setup. One security attack may occur during the client registration phase. The client registration phase has a vulnerability to accept false clients due to the absence of an authentication mechanism. An authentication mechanism has been previously made using Transport Layer Security (TLS). However, the TLS mechanism consumes more than 100 KB of data memory and is not suitable for devices that have limitations. Therefore, a suitable authentication mechanism for constraint devices is required. This paper proposes a protocol for authentication mechanisms using dynamic and event-based authentication for the MQTT protocol. The eventbased is used to reduce the computing burden of constraint devices. Dynamic usage is intended to provide different authentication properties for each session so that it can improve authentication security. As results, the applied of the event-based dynamic authentication protocol was successful in the constraint devices of microcontrollers and broker. The microcontroller, as a client, is able to process the proposed protocol. The client uses 52% of the memory for the proposed protocol and only consumes 2% higher than the protocol without security. The broker can find authentic clients and constraint devices capable of computing to carry out mutual authentication processes to clients. The broker uses a maximum of 4.3 MB of real memory and a maximum CPU usage of 3.7%.]]>

<![CDATA[The use of computer technology in manufacturing industries can improve manufacturing flexibility significantly, especially in manufacturing processes; many software applications have been utilized to improve machining performance. However, none of them has discussed the abilities to perform direct machining. In this paper, an integrated system for remote operation and monitoring of Computer Numerical Control (CNC) machines is put into consideration. The integrated system includes computerization, network technology, and improved holding mechanism. The work proposed by this research is mainly on the software development for such integrated system. It uses Java three-dimensional (3D) programming and Virtual Reality Modeling Language (VRML) at the client side for visualization of machining environment. This research is aimed at developing a control system to remotely operate and monitor a self-reconfiguration fixture mechanism of a CNC milling machine through internet connection and integration of Personal Computer (PC)-based CNC controller, a server side, a client side and CNC milling. The performance of the developed system was evaluated by testing with one type of common protocols particularly User Datagram Protocol (UDP). Using UDP, the developed system requires 3.9 seconds to complete the close clamping, less than 1 second to release the clamping and it can deliver 463 KiloByte.]]>
