<![CDATA[Warung Makan Leko is one of the restaurants in the Jakarta area that offers local cuisine, a diverse menu and delivery orders via phone order. Customers are one source of income for Warung Makan Leko. The amount of competition makes Warung Makan Leko have difficulty in retaining loyal customers. For this reason, further analysis is needed to find out who these potential customers are. Then an application was developed to classify customer data using the K-Means (clustering) algorithm. The data used as an example in this study is the sales transaction data of Warung Makan Leko. Run the process to calculate the total sales to customers and the number of transactions with customers to classify customer data. The K-Means clustering method tries to group the existing data into groups. Data in groups have the same properties. Customer data is grouped into two clusters, no and implicit. Each cluster is then classified based on the prioritized criteria. The cluster with the highest centroid value is the cluster that is rewarded, and the cluster with the lowest centroid value is the non-rewarded cluster. The results of this process form clusters, which are used for advice and consideration to determine sales strategy, namely to reward customers who rank higher in the cluster]]>

<![CDATA[Today's technology users are very diverse, namely from the younger generation, parents, experts, and ordinary people. Based on the results of the 2019 PISA survey on the world's education system, Indonesia is located in a low position at 74th out of a total of 79 countries. Based on research conducted in Sleman district, public knowledge about self-medication is still at a low level of 52.9%. Finding a job is not an easy thing in Indonesia. Pharzolution is a SaaS-based application to address issues of education, drug use, and information on job vacancies in the pharmaceutical sector. Respondents were made to 15 people consisting of 5 Pharmacy Vocational High School graduates, 5 Pharmacy D3 graduates or S1 Pharmacy graduates, and 5 pharmacists in the Jabodetabek area by applying the design thinking process to find out problems and solve appropriate solutions. Through interviews, the results obtained 6 suggestions that form the main features of the pharzolution application. The process of compiling the user interface display and user experience prototype is carried out through the figma website. The business model design process uses lean canvas which is an adaptation of the business model canvas. Pharzolution has 3 main features, namely pharducation, drug algorithm, and pharjobs]]>

<![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[Indonesia is one of the highest cigarette-consuming countries in the world. Therefore, the government is trying to control this through various efforts. One of them is by increasing the excise rate on tobacco products yearly with an average increase of 10.92 percent per year. However, this effort has not been able to reduce the number of smokers in Indonesia, which has increased by 8.8 million in the last ten years. This raises the fact that there is an increase in the circulation of illegal cigarettes in Indonesia. Therefore, the central and local governments formed task forces to control illegal cigarettes. This study aims to assist the task force in managing data on the circulation of illegal cigarettes by creating a data management application. This application was developed by implementing the Rapid Application Development (RAD) method. This method consists of four main stages: requirements engineering, system design, development, and implementation. This research has produced an Android-based mobile application that can assist the task force in managing illegal cigarette data. Based on the test results, this application has been declared successful through quality and functionality tests, so it is ready for use by the task force]]>

<![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]]>
