<![CDATA[In this paper we characterize the saline solution using Range Finder Ultrasonic (RFU). RFU is one kind of ultrasonic transducer that requires air as a transmission medium and commonly are used to determine distances. The advantages of this transducer are cheap and common in local market. Since it uses air as medium, the signal which is produced by transducer are easy to shape shift and has a very long noise tail wave. This phenomenon was seen in previous studies, when the transducer position was slightly shifted, the shape of the echo signal became very different. In this paper, we modified the input signal from the technique in the previous paper to improve the echo signal. Some modification of trigger signal from transmitter models were done, then calculate the echo signal to ensure the signal have smallest Signal to Noise Ratio (SNR) and noise tail wave. Furthermore, we did filtering process from echo signal and calculating using Fourier Transform which are performed to obtain accurate echo signal information of 40 KHz frequency. The results of this experiment is an improvement in the average error of calibration curve 0.1224221 (Vrms) and 0.14383881 (Vpeak). While the average error of the results of the normalization of the magnitude Fourier Transform of 40 KHz frequency is equal to 0.096973114. ]]>

<![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.]]>

<![CDATA[In this research, a mini boiler temperature control system is designed by using fuzzy logic controller (FLC). The FLC controls the valve of the incoming fuel. The mini boiler is fueled by gas, has length of 80 cm and diameter of 40 cm. FLC is designed in four different models based on the number of membership function of the temperature variable, i.e., three, five, seven and nine membership functions. The input variables are “temperature” and “error”, and the output variable is “valve”. There are two types of disturbance given to the control system, the disturbance of the system working at set point 125 °C, and disturbance by changing the set point values. In the first type, the FLC is able to reach 125 °C for all models. In the second type, the set points are varied to 100 °C, and 150 °C. At set point 125 °C and 150 °C, the FLC is able to achieve the pre-determined set points for all models. Mean while at set point 100 °C, the FLC can stabilized the system at point of 97.92 °C for the first model, and at the point of 100 °C for other models.]]>

<![CDATA[Object mapping based on location tracking methods has been widely used in various types of applications. Most tracking systems recently use existing technology and infrastructure such as satellite, cellular and wireless (RF) technology. These existing technologies are high-cost technology that needs authorized permission to be integrated to the novel technology. This research proposed a cheap point to point device technology to track a location of a transceiver using GPS in a portable infrastructure using Line of sight radio communication. The tracking system design is connected to the IoT system in order to be more accessible. The proposed system using GPS as an identifier of the transceiver coordinate location and 433MHz radio module as media communication between transmitter and receiver. The use of a 433MHz radio frequency module which is free-license adds value to the system so that it will be easily accessed. The design of portable and internet-based devices also gives a positive value in which the system does not have to depend on existing infrastructure and the system can also be reached even if it is placed in remote areas. The system test results show that the system can be well accessed up to a distance of 6.8 km.]]>

<![CDATA[Indonesia is the biggest producer of palm oil (Elaeis guineenis jacq). The palm tree is a primary commodity that posses a high economic value. Palm oil must be considered in terms of quality to produce optimal and high-quality oil. Previously, the stipulation of the palm tree characterization used manual and visual image utilization method; it may have weaknesses due to the dependency of individual sorting and coruscation factor. Therefore, this research is aimed to improve the performance of the previous method in identifying the ripeness of palm tree based on thermal imaging. The excess of thermal imaging was not related to the coruscation since the level of ripeness was both determined by the temperature and colour. The detection method of this research deployed the colour-based features that are Dominant Colour Descriptor and Color Moment. The DCD and Color Moment was the input to the K-Nearest Neighbor (KNN) method. The percentage of identification rate was 89%, and the identification of oil palm maturity level using thermal imaging is more efficient because it is done without human intervention and does not depend on lighting assistance compared to manual method and method of using RGB visual images.]]>

<![CDATA[IMU (Inertial Measurement Unit) is very important in navigation and control systems. The MU that has six degrees of freedom consists of three accelerometer sensors and three gyroscope sensors, each placed on three axes (x, y, and z) and orthogonal to each other. Vehicle monitoring systems that exist at present only provide information on the vehicle at two degrees of freedom (X and Y), so that the rotation of the vehicle is unknown. To be able to find the vehicle as a whole, namely the six degrees of freedom consisting of three position data and three rotation data, it would require an IMU with six degrees of freedom, namely by using the accelerometer and gyroscope sensor mounted on all three axes. In the research has been conducted design IMU sensors as the vehicle monitoring system with six degrees of freedom, so that can know the condition of the vehicle in six degrees of freedom, namely the position x, y, and z and rotation in three axes (roll, pitch, and yaw). IMU system uses an antenna transceiver for data transmission medium. We did the tests of IMU sensors in the initial output, motion response, and testing of navigation. Tests performed on laboratory scale to perform the calibration of the IMU sensor and then performed field tests using a motor vehicle. In laboratory-scale testing is not required transmitter and receiver antennas. Based on the results of the research shown the measurements of the attitude angle 90o with the axis of the rotary axis x, axis y, z axis with 7 variations of the test result in an average MSE of 2.277o x-axis, y axis of 2.519o, z-axis of 3.334o respectively and the measurement to the distance of 30 cm for 7 variations f testing resulted in an average MSE of 2.659 cm for the x-axis, 3.995 cm for the y-axis, and 2.142 cm for the z axis.]]>

<![CDATA[The decrease in quality and productivity of tomatoes is caused by high rainfall, bad weather and cultivation so that the tomatoes become rotten, cracked, and spotting occurs. The government is trying to provide training to improve the quality of tomatoes for farmers. However, the training was not effective so the researchers helped create a system that was able to educate farmers in the classification of damage to tomato quality. This system serves to facilitate farmers in recognizing tomato damage thereby reducing the risk of crop failure. In this study, the classification method used is backpropagation with 7 input parameters. The input consists of morphological and texture features. The output of this classification system consists of 3 classes are blossom end rot, fruit cracking and fruit spots caused by bacterial specks. The best accuracy level of the system in classifying tomato quality damage in the training process is 89.04% and testing is 81.11%.]]>
