<![CDATA[Paradigm changes are also occurring in the field of marketing which is shifting from a selling and marketing concept to a holistic marketing concept which is caused by rapid changes in the market and its supporting technology with the Internet as the main pillar. Based on data from https://databoks.katadata.co.id/ The Data Reportal report noted that there were 4.95 billion internet users in January 2022. This number increased 4% from 4.76 billion people in January 2021. As of January 2022, internet users in Indonesia it reached 204.7 million. This number covers 73.7% of Indonesia's total population. One of the sophisticated Internet facilities that is widely used by business people as a means to promote their products is through websites. Facilities that can change the existence of a business into unlimited information that can be accessed by people in various corners of the world without having to spend large amounts of capital are a promising offer from the existence of the Internet today. The results of this research explain the path coefficient (β) and t-test, all hypotheses that influence User Satisfaction are declared accepted. Then, referring to the results of the choices in the questionnaire, the Usability Quality (USA) variable has a fairly high influence on User Satisfaction compared to other variables. This is related to the quality of the website, which is attractive in terms of user interface and ease of operation. Of course, this creates a positive experience for users when accessing the Mitra10 website. It is hoped that Mitra10 can improve the quality of the website in terms of usability and service interaction quality because these variables have a significant positive influence on user satisfaction of the Tokopedia website. One way to increase usability is to improve the appearance of the website so that the menus on the website are easier to find. Mitra10 is expected to focus more on the service interaction side because it has an influence on high user satisfaction. If service interaction is improved, user satisfaction will also increase significantly.]]>

<![CDATA[Several alternate routes are displayed by the greedy algorithm, which is widely used in the closest travel route search application. This study employs the greedy method, which sets up a route map to quickly determine the shortest path. The goal of this study is to find the shortest path using a greedy algorithm. By using a greedy algorithm system to find the closest point to which the user's selection is made, the study's eight times with different points on the graph can be seen in the user's position. In an attempt to find the best solution, the greedy algorithm—which is renowned for its simplicity and effectiveness—iteratively chooses the best option available at each step. The greedy algorithm frequently gives priority to proximity when it comes to travel route optimization, and it might not always produce the shortest path overall. However, it's a well-liked option for some applications due to its quickness and simplicity of implementation. Notwithstanding its drawbacks, the greedy algorithm can offer insightful solutions for optimization and route planning issues. Users can make decisions more quickly and possibly find alternate routes they might not have otherwise thought of by using this algorithm to find the closest point in a travel route search application. The study's conclusions also emphasize how crucial it is to take user convenience and preferences into account when developing route planning systems. Future studies could look into ways to improve the greedy algorithm's performance and fix its drawbacks, like adding more heuristics or combining it with other optimization strategies. Overall, this study's findings validate the greedy algorithm's efficacy as a workable choice for locating the closest point in travel route search applications, providing consumers with a dependable and approachable navigational aid.]]>

<![CDATA[Timely graduation is very important for educational institutions such as universities, especially for students. Because it can prove that the University and students are able to undergo the learning process theoretically and practically. But many students do not pay attention to graduation, especially those who are already working or married. Therefore, analysis is needed to predict student graduation so that solutions can be found by the University. Data mining was chosen as a method to process data to get new information. The algorithm used in data mining is Naïve Bayes. The research stages include loading data into excel, cleaning empty data, selecting databases related to graduation and taking data from 300 students majoring in Informatics Engineering. The next stage is data transformation by categorizing student data, namely personal data attributes (gender, age, marital status, job status) and academic data (grade). Data testing, application of Naïve Bayes algorithm and accuracy testing were carried out with Rapis Miner software version 10.3.001. The results of data processing with Rapid Miner using the Naïve Bayes algorithm are shown with the Confusion Matrix and ROC Curve. The results of confusion matrix from data processing with Naïve Bayes in the form of accuracy, precision, and recall have the same result of 100%. The percentage of the Confusion Matrix indicates that the model created can classify correctly and accurately. The ROC curve depicted with AUC yields a value of 1, which means that the test showed excellent results]]>

<![CDATA[Payroll is one of the most important elements in an organization, company or government agency, where remuneration is a right that must be given to employees for the performance and services they have provided during a certain period. Policies in managing payroll are certainly not the same from one company to another. Because each company has its own standards in determining the amount of salary that will be given to its employees. The most important thing is that the salary given must meet the Regional Minimum Wage which has been determined by each region. Therefore, there needs to be good management in making payroll. However, currently there are still many organizations or companies that cannot manage their employee payroll well, because many still use conventional methods in calculating employee salaries. Under these conditions, of course it can cause problems. Problems that are often encountered include difficulties in recording employee salaries, delays in providing salaries to employees and inaccurate payroll reports produced. If this problem is allowed to continue, it will result in losses for employees. Therefore, to deal with this problem, it is necessary to develop a system with the hope that the resulting new system will be able to solve the problems faced in managing payroll. To support the development of this system, it is also necessary to select the right model that suits the needs of the organization or company. One of the models used is the Waterfall model. In the waterfall model, the stages that will be carried out in developing the system can be clearly identified, so that it is hoped that the final result will be an application that can be used in managing employee payroll information systems.]]>

<![CDATA[The library is an important part that must exist in the school. With a library, it is of course hoped that it can foster students' interest in reading and enrich students' knowledge. Even in this era, all types of information can be obtained anywhere and at any time with the increasingly rapid development of information technology. However, there are still many students who cannot enjoy the ease of getting this information. And there are still many schools that do not have libraries. Even if there is, the library is still very conventional. Where library data processing starts from processing book data, data on borrowing and returning books is done manually. This can cause problems in the library, such as notes written using handwriting, which can cause errors in reading if the writing is not clear. Besides that, documents in the form of cards or paper are often damaged and searching for data takes a long time. If this happens continuously it will certainly have negative impacts in the future. Therefore, schools with such conditions require the development of a library information system, especially for borrowing books. In carrying out system development, it is necessary to determine the right model to help carry out the development and so that the objectives of system development can be achieved. One of these models is the Rapid Application Development (RAD) model. In the RAD model we can clearly understand the steps that must be taken in developing a book lending information system, so it is hoped that a Book Lending Application can be produced so that it can help manage book lending information system data.]]>

<![CDATA[In administrative and banking environments, the use of Word templates that must be adapted to specific data before use is often necessary. The manual process of replacing data in these templates requires significant time and effort. Therefore, this research aims to design and implement an automation system that allows for the automatic replacement of data in Word templates. The method used in this research is the prototype method, enabling developers to create system prototypes that can be tested by users before further development is carried out. In the design stage, frequently used Word templates in business and administrative environments are identified and categorized. An efficient and accurate data replacement algorithm is then designed and implemented using a suitable programming language. The resulting automation system is designed in the form of a website, allowing users to input data to be filled into the template. Users can also preview the input data before downloading the customized Word file. The results of this research are expected to reduce the time and effort required to replace data in Word templates manually. The implemented automation system in the form of a website provides flexibility and ease of use for users who want to replace data in their Word templates. The prototype method allows for iteration and adjustment of the system based on user feedback, thereby increasing satisfaction and effectiveness in system use.]]>
