Abstract

Ranking of a tertiary institution, both state and private universities, can be the basis of the tertiary institutions of interest to prospective new students. The better the ranking of the college, the more popular the campus. In this study the author discusses the case of campus ranking in the city of Medan where the results to be received are the best campus decision making with the method used is the MAUT (Multi Attribute Utility Theory) method. The aim is to see what results can be given by using the MAUT method in determining the best campus in the city of Medan which results in ranking the campus in Medan. Does it provide optimal results or not. But every case that is solved using the methods in artificial intelligence, in this case the MAUT method is a method of the Decision Support System, certainly provides optimal results even though the results given are not complete or complete. Therefore, the writer has a vision going forward, conducting research in this field, especially for the case of campus ranking. In this study the variables used in determining campus ranking are Institutional, Student Activities, Lecturer HR, Research and Community Service, and Innovation. These five variables in the future can be added or subtracted as needed. The results obtained are optimal ranking results but are still limited to the reference model for internal institutions.

Abstract

Data security is most important today, because the rampant data theft resulting in a lot of misuse of data by irresponsible parties so that it makes us anxious as data owners, for data storage it is usually stored in the database. From these problems the idea emerged to create a cryptographic system where the system can secure data by encrypting and decrypting also make data fully save and then the data owned by the user. This study aims to secure the data in the database by encrypting the original data without destroying the original data when later after decrypted. To perform this security, a cryptographic methodology is used with both of  method that is Vigenere Cipher and Triangle Chain Cipher algorithms which are implemented in the application because both of methodology have same root that is classical cryptographic. This application will later be used as a medium for users to secure their data in the database so that later data theft will not to be easy. After doing fully research that produces applications that can implement combination of Vigenere Cipher and Triangle Chain Cipher algorithms,data in the encrypted database field is safe because encryption has been done to the data.

Abstract

Choosing a specialization in a study program is a must for students in semester 4 or 5 and above. This specialization aims to focus students' abilities in one area only. However, many students are wrong in choosing the right subject for them. Most of these students choose specialization based on follow-up without thinking about the impact it will have if the student is unable to take the courses given. For that we need an appropriate technique and calculation so that it is able to help these students in choosing the right specialization. Then a Decision Support System is used which can help in making decisions from the data and criteria used to produce an appropriate decision for students. The method used in this study is the Weight Aggregated Sum Product Assessment method or abbreviated as WASPAS. With the application of the WASPAS method in the selection of specializations, it is hoped that it will be able to provide optimal results, namely the selection of specializations that are in accordance with the abilities possessed by each student.roduce an appropriate decision for students. The method used in this study is the Weight Aggregated.

Abstract

Mining is one way to get cryptocurrency through the process of finding a new block that must be worked on by a miner. Choosing the wrong type of mining tools will greatly affect the results, speed and effectiveness of the process. Therefore, to overcome this problem, we need a system that can recommend choosing the type of bitcoin mining tools using the concept of a decision support system. There are several methods that can be used for decision making, but in this study the VIKOR method is used to recommend the selection of bitcoin mining tools. This multi-criteria decision-making technique is based on the theory that each alternative consists of a number of criteria that have values and each criterion has a weight that describes how important one criterion is compared to another. This research will produce an application that is used to solve the recommendation problem for selecting bitcoin mining tools using the VIKOR method. There are seven alternative bitcoin mining tools, namely Antminer S5, Antminer S7, Antminer S9, Avalon 6, SP20 Jackson, Antminer R4 and Antminer S2, The expected research results with the minimum alternative Q value was the best ranking

Abstract

In terms of maintaining goldfish there are several factors that must be considered such as water temperature, pH levels and feeding that must be considered. Traditionally, checking the condition of aquarium water is carried out routinely by paying attention to water color and odor, traditional methods still lack accuracy and time efficiency. In the handling of feeding, it is classified based on the time of feeding for goldfish. Therefore, an automation system is needed in this case to overcome the accuracy of checking and feeding routines. By utilizing a microcontroller system that is connected to a temperature sensor, pH sensor, servo motor, RTC and Fan. The pH sensor detects the pH of the aquarium water when the aquarium water is low the pH lowering servo activates immediately. If the pH is detected as high, the pH lowering servo will be active. The temperature sensor detects the aquarium water temperature, if the aquarium temperature is more than 30 C then the Fan will turn on, and when the temperature is back to normal, the Fan will turn off automatically. The RTC reads the feeding time on the Arduino Uno program, when it enters the feeding schedule, the feed servo will move 180? to pour the feed

Abstract

The world was shocked by the outbreak of a new virus that originated in the city of Wuhan, Hubei province in China and has spread to all corners of the world. This virus is Corona Virus Disease 2019 (Covid-19). The government as a policy maker has imposed new regulations so that everyone can leave the house and do work without having to worry about being exposed to the Covid-19 virus. One of the regulations made by the government is that everyone who will leave the house must wear a mask. However, the use of masks for a long time has the potential to cause headaches to increase respiratory tract resistance caused by carbon dioxide. It is necessary to have a mask that can filter the air properly so that carbon dioxide can come out of the mask directly and not be inhaled again. To overcome this problem, it is necessary to make a tool that can make air or carbon dioxide out of the mask. With existing technological facilities, the problem of breathing in carbon dioxide in masks can be minimized. One example is the MG811 sensor technology where this technology can detect the presence of carbon dioxide in the mask that comes out of human breathing. Based on this, this study discusses the automatic air filter system on an Arduino-based mask. The result of testing and implementing this system is that when the sensor detects excess carbon dioxide in the mask, then the supporting component of the system, namely the fan, will work to remove carbon dioxide in the mask.

Abstract

SMEs or Small and Medium Enterprises are business units that have an important role in the development of national economic growth, and are able to absorb labor in the processing and distribution of production results. The products of UKM are able to help the people's economy which becomes a new field of work. However, the obstacle in the business processes of these SMEs is the difficulty in getting the right consumers so that production results are not sold and cause losses. This problem is caused by the lack of good and appropriate promotion of the products of these SMEs. So we need a means or media so that these SMEs can properly promote their production results. For this reason the writer and the team carry out training activities for SMEs in the village of Bukit Lawang, Bahorok District, North Sumatra in the use of social media as a means of promoting production results. The training was held to be able to provide knowledge to SME entrepreneurs in promoting the results of their businesses appropriately to consumers through social media. Where social media is the most popular and very cheap promotional media at the moment.
