<![CDATA[One important aspect of running a successful motorcycle repair shop business is being able to control the inventory of motorcycle spare parts. Motorcycle spare parts in motorcycle workshops usually estimate stock by guessing only, which results in existing stock piling up unsold, because there is no calculation for the estimated sales stock of motorcycle spare parts for the next year, this is a constraint in the availability and need for spare parts stock. The author's purpose in this study is to determine the process of forecasting or forecasting the sales stock of motorcycle spare parts in a workshop, to design and make sales predictions in the workshop that are objective and measurable in accordance with past sales data, to apply sales predictions using the Trend Moment method in determining the estimated stock of spare part sales in each subsequent month. From the existing problems, the workshop will predict the sale of motorcycle spare parts. Application design that has been designed with a system that has been implemented using PHP programming language and database using MySQL, XAMPP using the process of forecasting motorcycle spare part sales using the Trend Moment method, starting from entering sales data in the previous period, to the forecasting process using the Trend Moment method to get results on how much stock of motorcycle spare part sales for the next month]]>

<![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[Digital image files are a form of information that is accurate and reliable enough to describe something, so the level of authenticity of this information needs to be maintained. Especially when sent via the internet as in chat-based applications such as Facebook, WhatsApp, Instagram and other social media. To maintain the security and confidentiality of digital image/image information, it is necessary to have a technique called cryptography. Cryptography is a technique or algorithm for changing data or information to be different from the original information. For example, in everyday life, there is a result of a design order that is still in the development stage that needs to be shown to prospective buyers, a drawing file or documentation image file that is private and confidential, so it is important to pay attention to its security. This research will use the combined performance of the Hill Cipher and Rivest Code 6 cryptographic algorithms in securing image files. The results of the Hill Cipher and Rivest Code 6 cryptographic algorithm encryption are able to disguise the image during the encryption process. And can restore to the original image in the decryption process. So that the encrypted image is safer to send via the internet or social media.]]>

<![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[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.]]>
