<![CDATA[One of the learning processes is to give assignments to students with the aim of increasing students' understanding of the material that has been given, besides that assignments can also be used as an evaluation tool for whether students have understood the material. The obstacle faced by lecturers is the process of checking and recapitulating the value of the assignment, where the value of this assignment will also affect the final score of students. Many lecturers use excel to record the value of this assignment, but this process still takes time, especially if the number of students is quite large. The purpose of this research is to create an application with the help of barcodes to help lecturers facilitate the process of recording assignments, by using this barcode the process of finding student numbers will be very easy and fast. The working principle of this application is, students, include their number on their respective assignment sheets in the form of a barcode, then after the assignment is checked and given a grade, the lecturer scans the student ID using a barcode scanner, the application will look for the student ID and the lecturer just enters value, with this system the process of recapitulating tasks will be fast and accurate]]>

<![CDATA[Search and tracking issues are important in determining the success of a system based on Artificial Intelligence. One that is well known is the Generate and Test method which is one of several heuristic search models in Artificial Intelligence terminology. Generate and Test is an algorithm that performs tests to find the shortest route in the case of a trip. Generete and test is suitable for measuring the smallest distance. The benefit of this research is to save time and money in traveling the distance to a city. How it works in this algorithm is to see the initial state as a star point and see the final state as a goal state. Perform all calculations to each distance provided that it starts from the initial strat and ends with the end strat. Count all values, choose the smallest value to reach the Final goal. If the search results have been found then the search is stopped, if not the solution then the search continues until it finds the smallest result to find a solution.]]>

<![CDATA[The purpose of this research is to determine the impact of using the Dikti Edu Tablet on student achievement in the Computer Assisted Language Learning Class. Through this research, of course, researchers can find out the relationship between the independent variable, namely the use of Dikti Edu tablets, and the dependent variable, namely achievement. The research method is a quantitative research model using a survey in the form of distributing questionnaires to 20 students of the English Education Program. After collecting data, the data were analyzed quantitatively through SPSS 22 and the statements in the study used a Likert scale of 1-4. Based on the research that has been done, it is found that there is an increase in the learning achievement of English Education students at Victory Sorong University. This is evidenced by the value of the relationship between Edu Dikti Tablets and Student Achievement in English Language Education is 56%, while achievement is 44% which may be influenced by other factors not examined in this study. With the Edu Dikti Tablet, students are able to learn independently, creatively and innovatively so that they become educators who are ready to compete in the community]]>

<![CDATA[Anesthesia is a very important step in surgery. Research on the fulfillment of the ideal criteria for anesthetic techniques continues. These inhalation anesthetics require slow induction times, are complex and expensive devices and cannot be performed if veterinary surgery is performed in the field. In this study, the technique used was anesthesia through gravimetric infusion. The purpose of this study was to monitor the dose of gravimetric infusion anesthesia using a load cell. The load cell sensor will send data to the NodeMCU to display the anesthetic dose that has been entered on the smartphone. The results of the gravimetric infusion anesthetic dose monitoring system produced a very small error of 0.004%. The error in reading the anesthetic dose is very important because the main factor of this gravimetric infusion anesthetic is the right dose to meet the criteria for ideal anesthesia.]]>

<![CDATA[As a result of processing data in the form of documents too often, document files accumulate on storage media and make the storage media lack free space. One solution that can prevent this is data compression. In this study, we will try to analyze the performance of lossless algorithms, some of which are: Goldbach's Algorithm, Fibonacci's Algorithm, Rice Codes Algorithm, Additive Codes, and Yamamoto's Recursive Codes Algorithm. The main reason why a comparison is needed is to see which algorithm is the best, it is worth doing as a basis for making applications that can compress data because application users want the best results for them, and in this case, are those that can compress files and produce the smallest size compared to other algorithms. The data to be compressed is text data. The results obtained from the test are the Goldbach Codes and Fibonacci Codes algorithms are superior to the third algorithm and several times have the same results, namely compression ratios of 60% to 68% and space savings ranging from 32% to 40%.]]>

<![CDATA[Social media is a new life influenced by the development of information technology. This development raises problems in comments and criticism on social media and the rapid growth of hoax information that affects many sectors of life. This article is the development of two journals: The Development and Implementation of Wise Netizens (E-Commentary) In Indonesia & Social Media and Changing Communication Patterns. The method used is the Johari window, and this method is developed and combined with the concept of comments and criticism on social media. The result of this article is a formula N=K.C2, a unique formula made for netizens and the seven stages of wise netizens (The maturity level of netizens). Furthermore, this formula and framework will provide netizens with a solution to assess them. To what extent a netizen has become wise in making comments and criticisms on social media? Furthermore, these stages will be used to find out, analyze and assess the extent to which comments and critics made by netizens have reached a level that has a standard of communication quality, share their knowledge, and have a two-way discussion.]]>

<![CDATA[Depth First Search Algorithm is a search process to find the right solution that requires short memory and time in finding the Goal. The problem in this research is the difficulty of salesmen to find alternative short routes to arrive at the final node as consideration for finding solutions. The purpose of this study is to find the shortest path so that salesmen can easily and quickly get to the final solution by saving time and mileage. The Generate And Test concept consists of combining the Depth first search algorithm with the backward tracking process. All processes must be completed before the testing process is carried out. If the General And Test process is carried out sequentially or systematically, it will get the best value in finding a solution, the weakness if the search process is large or extensive then the search process takes a very long time. How it works Generatr and test, namely 1. Generate possible solutions in the form of state states with the concept of a one-position path to the destination path. 2. Test, select whether the solution can be accepted according to the existing criteria 3. If the solution has got the Goal then the search is stopped, if not then the process is continued until finding a solution. The final result of testing the shortest route is A-B-E-J-P-S-U = 25+21+24+24+17+18=129]]>
