<![CDATA[Many industrial applications use servo motor because of its accuracy and user-friendly, but by using it in an application, a higher cost is required. To make an actuator with good precision and universal purpose but with lower cost, a position control system for brushless dc motor was built. To achieve a better precision in the position control for brushless DC motor, the system is utilized with a microcontroller ATmega 2560, an absolute encoder as a position sensor, and also Proportional-Derivative closed-loop control algorithm. In the final test, we obtained that the system worked well on average angular speed about 3.88º/ms and angle tolerance about 1º.]]>

<![CDATA[In this globalization era, the internet has been the main media which everyone used to exchange information, from the public such as sport to top secret such as military data. Hence, the requirement of data hiding method called steganography is rising. Steganography is hiding the secret information into another media so that it could be transferred publicly, but only the authorized users could access it. There were two main problems in the data hiding technique: the capacity of the secret and the quality of the generated stego data. In this proposed method, we combined digital image processing called interpolation, used it to predict the new pixel value to hide the secret bit in purpose to increase the bit data capacity with the consequence the reduction of the stego image quality. The experimental result showed that the capacity has increased from that of the previous research.]]>

<![CDATA[Ad hoc wireless network performance often declines caused the onset of congestion on the process of sending data. TCP Congestion Control used to solve these problems. TCP Cubic is one variant TCP Congestion Control. This research was conducted with the test and compare between variable value b=0.2 with the value of the variable b to be used in ad hoc wireless networks. This research was conducted with the experimental method using network simulation software NS-3. The results showed that the value of variable b is the right on ad hoc wireless network with packet loss by 5% to generate optimal congestion window max is b=0.5 and the average throughput optimal is b=0.1]]>

<![CDATA[In recent years the use of wireless technology is growing rapidly. Not only limited to the use of cell phones but also other wireless devices that use the air media as the information transmission line. The antenna is a very important component in wireless devices because its function is to convert electrical signals into electromagnetic signals and vice versa on transmitting the information in the air. One of the technologies that can overcome this is the use of microstrip antennas. The microstrip antenna is a lightweight, easy to fabricate so that can be placed on almost any type of surface and small size compared to other types of antennas. Because of its properties, microstrip antennas are highly suited to current needs. This antenna can be integrated with other telecommunications equipment in small size. This paper describes the design and realization of microstrip meander-line antenna at working frequency 915 MHz to be integrated on a telemetry measuring device pH meter water. The integration of the meander-line microstrip antenna on the pH meter measurements is capable of transmitting pH data at unobstructed conditions with a maximum distance of 210 meters, and in a blocked condition, a building is capable of transmitting pH data with a maximum distance of 110 meters. ]]>

<![CDATA[A remote control operator enables a robot to perform in a hazard or area which can not be reached by humans. To control the robot, several researchers have equipped a robot with a system which can give others types of feedback information, besides of visual feedback from the robot. One of the feedback types is haptic feedback. The aim of this feedback is to make the operator become immersed with the robot. The existing researchers are using electro-mechanics system. However, these systems are complex, bulky, and hence prevent a seamless embodiment between an operator’s body. The objective of this research is to develop a haptic feedback system combined with stereo vision feedback which compact, versatile and easy to fit. This system is tested to accomplish the task using mobile robot and robot arm. The result shows that this system can help the operator to control robot better.]]>

<![CDATA[This article discusses the design of light follower chair prototype with speed adjustment of DC motor according to light intensity using microcontroller ATmega328p. This prototype provides a solution for a chair to be back on the position under the table automatically by using a light follower robot principle. There are many possible positions of a chair after being used: perpendicular or sideways to the table. As the positions after being used are varied, the light is used to direct the chair toward under the table since the light can reach the area around the chair except for the back area. This prototype functions well if the chair is heading to the table and is not designed to function in the backward position. LDR (Light Dependent Resistor) sensors are used to detect the light. As the source of light, 1 W high power LED is put under the table. A microcontroller ATmega328p is used to execute the input and output of this system. Two DC motor are used as actuators to control the movement of the chair toward the light under the table. Ultrasonic sensors HC-SR04 are used to measure the distance between the table and the chair so that the chair can stop at the desired position.]]>

<![CDATA[Telecommunications and robotics technology is being developed to assist and facilitate the work of a human. In the field of telecommunications particularly smartphone has reached the planting of operating systems like android until planting sensors such as an accelerometer, gyro, proximity, etc. We would like to take advantage of the accelerometer sensor on a smartphone as robot control. We will compare the use of Sugeno Fuzzy Logic and Mamdani Fuzzy Logic to determine the best control method. The basic components of the robot are the Bluetooth module HC-05 as a medium of communication with the android, arduino as the control system and actuators such as DC motors drive the rear wheels to adjust the speed of the robot, and servo motor drives the front wheels to adjust the degree of turn robot. In robot’s movement test, 4 of 8 trials or approximately 50% stated better Sugeno Fuzzy Logic than Mamdani Fuzzy Logic in terms of linearity. In robot's controller response test, for Sugeno Fuzzy Logic method the average delay is 0.41 seconds, and for Mamdani Fuzzy Logic method the average delay is 10.80 seconds.]]>

<![CDATA[An earthquake is a natural disaster caused by the movement of the earth plates or from below the Earth surface. The impact of the earthquake could lead casualties and other losses whether material or immaterial. The evacuation process of the victims must immediately proceed. The SAR (Search and Rescue) team has a duty to rescue victims who trapped in the rubble of the building. But information about the position of the victims could not be known precisely, and the environment around the location of the disaster is still very dangerous that might endanger the safety of SAR Team. In this research, a robot path pointer was designed to help SAR team in locating the victims. The method used in this research is the robot wirelessly controlled by SAR team at SAR team’s post with remote control. The robot searches in the rubble of the building and sends the victim’s location information to SAR team. This robot pointer research aims to find safe routes for SAR team of the victim’s location to reduce the risks that may harm the SAR team. The robot will give the main results of the pointer in the form of location coordinates and routes of the victim so that the SAR team only have to follow the route. Robot pointer guides the SAR team to the location of the earthquake in a short and less risky path for victim evacuation.]]>
