Abstract

Accompanied by the development of information technology, communication technology has developed rapidly. One sector that is developing in the field of tourism which contributes to more interactive information through the internet. Where Maybrat Regency has considerable tourism and cultural potential, it is managed by the Maybrat Regency Tourism and Culture Community which is very useful if managed well and effectively. This is to improve the economy of the community, the quality of human resources, through tourism assistance that enables increased regional pride. Accurate presentation of the area that can be used to increase revenue in the region itself. Now there is not enough information about tourist objects in Maybrat Regency so that not many tourists and people know the potential of tourism objects. The system development model used is the prototype model. By building interfaces using Adobe Dreamweaver CS6. The database is stored using php and displayed via XAMMP. This system is also built on the framework of a system that is a code igniter.

Abstract

The utilization of a 3 phase induction motor is increasingly developing, so research on speed regulation in 3 phase induction motors is also increasingly widely studied. This is because the use of 3 phase induction motors in the industry and especially hybrid vehicles are increasingly being developed. But there are some disadvantages of induction motors, one of which is the characteristics of non-linear parameters, especially rotor resistance which has varying values for different operating conditions, so it cannot maintain its speed constantly if there is a change in load. This, of course, can affect the performance of an induction motor. To get a constant speed and better system performance on load changes a controller is needed. This study aims to model direct-quadrate parameters (D-Q) using the Field Oriented Control (FOC) method based on the Proportional-Integral (PI) controller. With the d-q parameter controlled, the induction motor will be more stable, because the d-q parameter determines the stability of the change in torque and flux in the induction motor. Proportional-Integral (PI) control used is a classic control system that is easy because it does not need to look for a mathematical model of the system, but it remains effective because it has a fairly stable system response, by setting the best combination of proportional (Kp) constants and Integrator constants ( Ki). In the results of the implementation, it can be seen that the use of FOC can be used as an approach in terms of setting the speed of the induction motor, and with the use of the PI control can help the output response get better with a shorter response time to reach the reference value.

Abstract

The East Java Governor Election 2018 is also felt in the virtual world especially Twitter. All people freely argue about their respective governor candidates, memorandum raises many opinions, not only positive or neutral also negative opinions. Media growth is so rapid, revealing a lot of online media from the news media to social media. Today's social media is not only used of friendship, but also for other activities. Promos of trading or buying and selling, until political party promos or campaigns of candidates for regents, governors, legislative candidates until presidential candidates. The research objective is to conduct a method of Sentiments Analysis for Governor candidates East Java 2018 in twitter with optimal and maximum optimization. While the benefits are to help the community conduct research on opinions on twitter which contains positive, neutral or negative sentiments. Sentiments Analysis for Governor candidates East Java 2018 in twitter using non-conventional processes that save costs, time and effort. The results of Khofifah's dataset are 77% accuracy, 79.2% precision, 77% recall, 98.6% TP rate and 22.2% TN rate. For the results of GusIpul dataset, accuracy is 76%, precision 74.4%, recall 76%, the TP rate is 93.8% and the TN rate is 52.9%.

Abstract

The rice program for poor families or commonly known as Raskin is one of the government's efforts to reduce the burden of expenditure on poor families. The Raskin program is to reduce poverty and maintain the food of economically disadvantaged people so that all parties are expected to participate in the success of this program so that it can be implemented properly and is beneficial to the community. In general, the problems that occur in the assistance of Poor Rice assistance are still not optimal, because at the time of selection of poor rice recipients there is no system that supports so that during the selection process still using estimates only and there is no calculation at the time of selection of poor rice recipients. So that few or many people sometimes protest because people are supposed to get help but they don't get the assistance, and vice versa. The purpose of this study is to help the committee to receive poor rice assistance in selecting people who are entitled to receive assistance, especially in the district of Banawa. The research method used is the software development method using the prototype method and decision-making method using the AHP (Analytical Hierarchy Process) method. Based on the results of testing conducted with the black box technique, the results show that the decision support system for receiving poor rice assistance can help the sub-district, especially the committee in selecting poor rice aid recipients, by comparing the criteria for each alternative and showing the value the highest of alternatives means that the alternative is the main choice for receiving poor rice assistance.

Abstract

UDP is a data transmission protocol on the Internet that allows data to be sent in realtime and become a development base of various services such as IPTV, VOIP, VOD, and video conferencing. The multicast network was a solution to provide better service to many public needs with the concept of simplicity and efficiency. Dense traffic situation triggering a packet loss and delay that not tolerated by some services, especially multimedia streaming service, while UDP does not guarantee the quality of service so that the necessary traffic management method that serves as a traffic controller to the congestion in the network. This study analyzes the performance of technology based on Active Queue Management (AQM) congestion control in a multicast backbone network based on Protocol Independent Multicast – Dense Multicast using Droptail, Deficit Round Robin (DRR), and Random Early Detection (RED) algorithm, which is simulated using NS2. The simulation results show that the congestion control algorithm, DRR provides the best performance with a balanced value of mean delay, mean throughput, and the mean loss. RED is a congestion control algorithm which has the best queue management mechanism but not able to suppress the mean loss in each scenario tested because RED has a small amount of buffer size, Droptail not an appropriate algorithm for multicast networks implemented in, the absence of an interrupt mechanism trigger data services will have a tendency towards a particular data packet.

Abstract

Message encoding is an art and science to maintain news or data, learn mathematical techniques related to aspects of information security such as data confidentiality, data validity, data integrity, and data authentication. The process of encoding and inserting messages with the Vigenere Cipher and LSB methods is the first step in inputting text and keyword files, then text files and keywords are converted into decimal numbers, then processed according to the Vigenere Cipher formula, the ciphertext is then transformed into binary form it is inserted into the image by means of each bit of the ciphertext in the last bit of the image, so it is expected that the data sent is not easy to read by third parties. The vigenere cipher algorithm and the LSB (Last Significant Bit) technique can be used as a solution for the security of secret messages that are inserted into the image, can be re-revealed exactly the same as the original form and do not experience the slightest damage.
