There have been tremendous efforts on robot telemanipulation by the human arm through various sensors. Some approaches use mechanical or electronics sensors attached to the human arm. Other uses non-touch sensor such as camera, Kinect, or Motion Leap. The extracted features of the human arm are often mapped to corresponding joints of the manipulated robots. This condition leads humans to stick to stiff movements. In contrast, there is a need for an actor doing telemanipulation on stage with natural movement. The more natural the movement during telemanipulation, the more attractive to the audience. In which, the audience feels as if the actor communicates with the robot. And the robot understands what being instructed by the actor. Indeed, this paper considers the natural movements of the actor by examining the motion pattern of the human arm posture as the manipulation reference. A Myo Armband sensor is used in this paper to extract the arm posture. At the same time, the movement is observed to obtained the motion pattern. Later both information is then used for manipulating a robot. In order to validate the proposed method, a serial manipulator robot is utilized. Some experimental results show that the arm posture and the pattern of changing from one posture to another can be extracted and used for manipulating robot movement.

Even in new decades, modern communication technology is still affected by natural and man-made disasters, which threatens people’s lives and make the internet or mobile phone networks unavailable for use. The Design and Implementation of an Emergency Datacasting System using the 2-meter Amateur Radio Band prototype consisting of microcontrollers and walkie talkies operating on the 2-meter amateur radio band of 144-148 MHz. It is used to enable a two-way communication system, even without cellular service and internet, between the community, barangays, public service groups and local/national government agencies related to disaster response. With this, responding to the victims of calamities most especially to areas or communities that has no service, will be easier and faster. Once the system was on, radio transceivers in each base station communicate with each other. Wi-Fi enabled device detects and connects to an access point provided by the microprocessor, which could let 255 devices connect. When connected, it will be redirected to a specific IP address where they can send/receive private or emergency messages to and from users and admin. Users from different base stations meet at a common webpage. Microcontroller serves as the modem, which encodes and decodes the information to and from audio frequency signals, respectively. It is fed to the walkie-talkie to transmit/receive tones. Using a statistics method, the device is said to be 100 percent accurate through several tests receiving the same message without any errors, 97.6 percent reliable in the time, spanning at 8 hours through its transfer time and having an internal consistency of ‘Good’ for the user-friendliness of the webpage interface. The device improves existing datacasting systems since it does not depend on mobile networks, and it commonly uses a one way, not the two-way distribution of information.

This study aims to develop a model of decision support systems (DSS) for the selection of the best lecturer at the Faculty of Information Technology of Universitas Budi Luhur using a combination of Analytical Hierarchy Process (AHP) and Simple Multi-Attribute Rating Technique (SMART) methods. In this study, 12 (twelve) criteria were used to select the best lecturers: Educational level, Academic functional position, Lecturer Certification, Lecturer Semester Performance Index, Number of Respondents, Average Number of Meetings, Number of Research, Number of community service, Number of Publications, Number of Grants, Discipline submit final exam scores and Faculty Discipline.The results of the calculation of the consistency ratio (CR) for the best lecturer selection criteria obtained CR values = 0.06. The calculation results are not more than 0.1 or 10 percent, so the comparison of the best lecturer selection criteria is consistent and does not require revision of the assessment. Quality Testing of DSS application software for the best lecturer selection was tested based on 4 (four) McCall method variables, namely Functionality, Reliability, Usability, and Efficiency. The overall test results show that the quality of the application of the decision support system for the selection of the best lecturers has a "Good" criterion of 78.20 percent.

Heat recovery steam generator (HRSG) is an equipment part of the combined cycle power plant (CCPP), which consists of the gas turbine, HRSG, and steam turbine. HRSG performs a significant role in defining the efficiency of the CCPP. The fault condition at a subsystem or component of HRSG could cause failure in entire CCPP systems. Therefore, the fault potential should be identified, and the failure should be mitigated once it occurs. The objective of this study is to determine the alternative control structure which can be applied in the HRSG system in case of major fault and to determine which the most optimum alternative control structure based on reliability and cost analysis. First, the fault is determined and ranked based on the severity of the effect. Restructuration will be done for any major fault with severity rank 8 and above. The alternative control structure will be determined, then reliability and cost analysis will be applied to those structures to choose the most optimum alternative structure which will be applied in the system. Modeling and simulation will be done using MATLAB Simulink. Closing the blowdown valve, reducing the opening of the steam outlet control valve, and the combination of the previous two structures are the alternative structures that can be applied in HRSG systems in case of complete loss in the economizer outlet control valve. The third structure is the most optimum alternative structure based on a reliability and a cost analysis. It has reliability rate of 3.99 and cost of $12,078.87. The third structure also has the longest retention time of 436 s.

Parkinson’s disease attacking 1 percent of the elder population in this world, with one of the main symptoms of this disease being resting tremor. Until now, Parkinson’s disease information acquisition can only be done through patients’ visits to clinics or hospitals, whereas the aspects of the disease are also shown during in-between those visits. In this research, we develop an Electromyography (EMG) based remote-monitoring systemin order for patients are able to be checked more frequently and the results are in always-renewed information. This monitoring system utilizes NodeMCU as the compiler component and ESP8266 WiFi module and web server. The data acquired from an arm of a tested person will always be read in real-time and can be displayed on web-based platform. From the data acquired, they are processed in detail for pattern characteristics analysis. We have successfully carried out the experimental test by displaying on the web server-based monitoring system.

Enterprise Resource Planning (ERP) is a package of systems and software used by enterprises to manage their daily business activities, such as financial management, procurement, production, projects, human resources, and others. This system can facilitate business with real-time and accurate information so that the leaders can make business decisions well. The use of ERP in a manufacturing company usually stops only in the administrative department and does not reach the production machinery. In this paper, the researchers propose a way of interconnecting the ERP system with parts of the production machine to get more energy savings and speed up the time commencement of work. By using signal lamps that are connected to the ERP system and communicating through Message Queue Telemetry Transport (MQTT), the staff in the production machine area can immediately find out the status of the readiness of materials and production equipment in the inventory section.

Renewable energy can cause problems in the quality of electric power, such as harmonics. The reason is that solar power plants and wind power plants use power electronic instruments such as inverters, rectifiers, buck, boosts, and so on. These devices are used to charge batteries and are also used for load supplies. Electronic power devices can cause hormones in the electric power system if connected to the grid. For this reason, power quality assessment is needed on the power system, whether THD (Total Harmonic Distortion) more than the tolerance limit of 5 percent. If THD more than 5 percent, mitigation is needed to reduce THD. This research was carried out in the laboratory Department of Electrical Engineering. The results of the THD-V measurement at this location are 19,19%. The method uses a shunt passive filter and detuned reactor to reduce THD. This research will be made into 2 scenarios. The first scenario uses only a shunt passive filter and the second scenario uses a hybrid shunt passive filter with the detuned reactor. The purpose of being made into 2 scenarios is to prove that the detuned reactor can optimize the shunt passive filter. The results of these scenarios are the first scenario, harmonic mitigation using only the passive shunt filter can reduce THD-V to 3,39 percent. The second scenario is that harmonic mitigation using a combination of passive shunt filter and the detuned reactor can reduce the THD-V to 3,07 percent. It can be concluded that the role of the detuned reactor can improve the performance of shunt passive filters. Detuned reactor functions to limit the current entering the filter and can reduce the harmonic effects arising from the harmonic filter itself.

Students are one of the substances that need to be considered in relation to the world of education, because students are translators of the dynamics of science, and carry out the task of exploring that knowledge. As a subject with potential and, at the same time, objects in their activities and creativity, students are expected to be able to develop their qualities. The quality can be seen from the academic achievements achieved, which are evidence of the effort earned by students. Student academic achievement is evaluated at the end of each semester to determine the learning outcomes that have been achieved. If a student cannot meet certain academic criteria to be declared eligible to continue their studies, the student is declared to be not graduating on time or even dropout (DO). The high number of students not graduating on time or dropouts at higher institutions can be minimized by the policies of higher institutions by directing and detecting at-risk students in the early stages of education. Therefore, in this paper, we present the use of Fuzzy Soft Set Classification (FSSC), which is based on the Fuzzy Soft set theory to predict student graduation. The 2068 dataset was taken from the Directorate of Information Systems, Ahmad Dahlan University. The results showed that the FSSC reached up to 0.893292 in terms of accuracy. So, it is expected to be able to detect students at risk in the early stages of education so that higher education can minimize students not graduating on time or dropout by providing appropriate treatment and designing strategic programs.

So, it is expected to be able to detect students at risk in the early stages of education so that higher education can minimize students not graduating on time or dropout by providing appropriate treatment and designing strategic programs.","PeriodicalId":375166,"journal":{"name":"2020 International Conference on Smart Technology and Applications (ICoSTA)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126862690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The contribution of this paper to analyze the effect of wind power plants’ existence as distributed generation (DG) to short circuit currents in electrical power systems. Testing of short circuit simulation has performed on the IEEE 69 bus standard. In short circuit simulation used four different types of wind power plants. The first type of wind power plant is Fixed-speed conventional induction generators (FSCIG), the second type is Variable slip induction generators (VSIG), the third type is Variable speed doubly-fed induction generators with rotor-side converters (DFIG), and the fourth type is Variable speed with full converter interface induction generators (FCIIG). For comparison, 7 scenarios have made for each type of wind power plant. The first scenario has simulation without wind power plants or distributed generation. The second scenario has a wind power plant (DG) placed on the upstream side of the electrical power system near the grid. In the third scenario, DG has placed in the middle of the electric power system to supply a large amount of load. In the fourth scenario, DG has placed on the downstream side of the electric power system to supply small loads. Whereas in 5th, 6th, and 7thscenarios have combinations of 4 types of wind power plants have placed on the upstream side, middle, and downstream side of the electrical power system. The results of all these simulations have compared, starting from the smallest to the largest short circuit fault current.
