<![CDATA[The research discusses some experiments to control the level of liquid inside a tank by using PID controllers which can be divided into four categories. The experiments describe the effect of P, I, and D element. It also discusses the best possible controller, which is a PI controller, for the liquid level tank system. The liquid level controlling is done by adjusting the voltage pump which will further regulate the flow rate of the fluid entering the inlet valve. The liquid that flows through the outlet valve is considered as the disturbance variable to the system. The liquid tank sensor needs to be calibrated prior to the experiments. Calibration can be done manually by using a digital multimeter or by using the computer sofware that is connected directly to the plant system. Set point and PID parameters are determined by the UniTrain and the computer interface. In these experiments, PI controller has the best result with a medium proportional gain (KP = 5) and a small integral gain (TN = 0.2).]]>

<![CDATA[Zone dynamization is carried out in the Zone Routing Protocol to allow the adaptation of the routing protocol to VANET network conditions. Zone dynamization is accomplished by periodically updating the radius within a configured time period. The value of link stability from the factors that influence network conditions is used as a reference in the radius value’s renewal process. From the test and simulation results, speed is the most dominant factor in link stability composition. Comparison between ZRP and zone dynamics against traditional ZRP shows better performance than ZRP with zonal dynamics when measured from metric analysis of packet delivery ratio, delay, and routing overhead. The increase in ZRP performance can occur because the zoning dynamics carried out make ZRP more adaptive to network conditions so that it does not work too proactively or reactively. ]]>

<![CDATA[One of effective diversity techniques to combat fading on wireless channel is a cooperative communication system in which a source sends information through several relays and then forward it to a destination. A cooperative communication system has shown increased the system performance and reduced the energy consumption. However, it depends on the used relay mechanism that is relay protocols such as quantize and forward (QF) and amplify and forward (AF). In the previous research, energy efficiency of AF relay has investigated for a single-relay cooperative system, but multi-relay is more practical. Therefore, this research focuses on power efficiency in multi-relay cooperative communication system using QF protocol. The research method used is mathematical analysis and computer simulation for outage probability and power efficiency in the multi-relay QF. Simulation result found that multi-relay QF system could provide a high power efficiency, but the efficiency is reduced when the distance ratio increases. Power efficiency can be increased by adding the number of relays in the system. A comparison of power efficiency for QF and AF protocols has simulated, in which power efficiency of multi-relay QF is higher than that of multi-relay AF at distance ratio and power transmit. Thus, multi-relay QF system can provide high performance and power efficiency in the cooperative communication system.]]>

<![CDATA[Qurbani is an Islamic ritual animal sacrifice that is carried out during Eid-Adha; one of the two major Muslim holidays. In Indonesia, every village normally has one mosque that takes charge of organizing any related Qurbani activities, from collecting money, creating slaughter schedule, to distributing the meat for the recipients. The current management of these activities is done manually and by hand, which can potentially have errors. Therefore, this research aims to develop and evaluate the usability of a web-based application that will in part take care of Qurbani-related activities. This application is designed and developed using the Scrum methodology. The application as successfully developed and its functionalities are as expected based on design. The application was then evaluated using System Usability Scale (SUS) with 10 respondents. The application obtained the average score of 91.25 which falls into A or excellent category.]]>

<![CDATA[The emergence of Vehicular Ad-hoc Networks (VANETs) as part of the Intelligent Transportation Systems (ITS) technology development was expected to become an advanced method to solve the transportation system problem. The implementation of VANETs is expected to provide a new solution for traffic management strategy. Its main targets is to continue prioritizing traffic safety and to prevent the accidents on the roads. One of the VANETs problems before being implemented in the real world is the degree of freedom of the vehicle's mobility that limited by the road topologies. Various modellings and simulations have been performed to produce the most realistic mobility model. However, those models had become new paradigms due to various factors that limited them. The presence of the federated mobility model as an approach for traffic mobility modeling is considered to be able to provide more realistic and accurate VANETs simulation. Therefore, this article presents some brief reviews and contrast a number of the simulation and mobility models that have been used widely as compared to the federated mobility models that have developed until the present. The article's objective is to facilitate a better understanding of the traffic mobility modeling for the VANETs simulation that started from the interaction process until the integration between simulators. The understanding of the traffic mobility models will complement the knowledge that enable to perform the simulation of the VANETs implementation approaching the real conditions.]]>

<![CDATA[Heart disease is one of the leading causes of death in the world. Early detection followed by therapy is one of the efforts to reduce the mortality rate of this disease. One of the leading medical instruments for diagnosing heart disorders is the electrocardiogram (ECG). The shape of the ECG signal represents normal or abnormal heart conditions. Some of the most common heart defects are atrial fibrillation and left bundle branch block. Detection or classification can be difficult if performed visually. Therefore in this study, we propose a method for the automatic classification of ECG signals. This method generally consists of feature extraction and classification. The feature extraction used is based on information theory, namely Fuzzy entropy and Shannon entropy, which is calculated on the decomposed signal. The simulated ECG signals are of three types: normal sinus rhythm, atrial fibrillation, and left bundle branch block. Support vector machine and k-Nearest Neighbor algorithms were employed for the validation performance of the proposed method. From the test results obtained, the highest accuracy is 81.1%. With specificity and sensitivity of 79.4% and 89.8%, respectively. It is hoped that this proposed method can be further developed to assist clinical diagnosis.]]>

<![CDATA[Developing technology can facilitate work activities, one of which is technology in the field of robotics. One of the purposes of creating the robot was to assist in investigating suspected targets. The target can be a gas source leak object. On the other hand, gas leaks in industrial estates have a large impact on the environment. Robots are needed to facilitate the inspection process of targets suspected of gas leakage. Robots generally have systems that are integrated with sensors as interfaces and intelligent computing. In this study mobile robots and manipulators have been designed and have the purpose of inspecting objects suspected of being gas leaks. This robot system is called a mobile robot manipulator equipped with a wireless camera for object detection, two gas sensors for aroma detection, each sensor is mounted on the end-effector manipulator and next to the camera. The methods used in robots are fuzzy logic and cubic trajectory. Fuzzy logic is used to navigate robots to objects, and cubic trajectory for navigating manipulators based on the specified route. In the experiments that have been done, the mobile robot can navigate to the target until it stops at a distance of 20cm, and the manipulator is also successful in navigating. In the testing instrument, two leaking points have been determined. Each point is tested six times. The robot succeeded in detecting gas leaks with a success rate of 91.67%, and the position of coordinates read by the manipulator can be observed through the monitor.]]>

<![CDATA[Nowadays, clothes with various designs and color combinations are available for purchasing through an online shop, which is mostly equipped with keyword-based item retrieval. Here, the object in the online database is retrieved based on the keyword inputted by the potential buyers. The keyword-based search may bring potential customers on difficulties to describe the clothes they want to buy. This paper presents a new searching approach, using an image instead of text, as the query into an online shop. This method is known as content-based image retrieval (CBIR). Particularly, we focused on using color as the feature in our Muslimah clothes image retrieval. The dominant color descriptor (DCD) extracts the wardrobe's color. Then, image matching is accomplished by calculating the Euclidean distance between the query and image in the database, and the last step is to evaluate the performance of the DWD by calculating precision and recall. To determine the performance of the DCD in extracting color features, the DCD is compared with another color descriptor, that is dominant color correlogram descriptor (DCCD). The values of precision and recall of DCD ranged from 0.7 to 0.9 while the precision and recall of DCCD ranged from 0.7 to 0.8. These results showed that the DCD produce a superior performance compared to DCCD in retrieving a set of clothing image, either plain or patterned colored clothes.]]>
