<![CDATA[Investors must predict stocks correctly in order to maximize profits while avoiding bankruptcy. But the stock market situation is difficult to detect. His changing behavior is influenced by various factors such as the political situation, the company's and global economy, that are available through the news. This study aims to develop a model that can predict stocks more accurately by combining stock technical indicators and news sentiment. Genetic algorithm (GA) optimizes several stacked decision tree-based ensembles using the stacked-generalization method with the meta-learner concept used in this study. There are five main stages of the methodology, starting with stock and news data collection, data preprocessing, feature extraction and data analysis, then model development. A series of GA crossover and mutation parameter trials gave optimum results for searching combinatoric hyper-parameter models with an accuracy of 81.63% and an f1-score of 82.21%. The evaluation of the model on the combination of dataset types was able to increase the prediction accuracy from 75.91% to 81.63%, and the f1-score from 77.56% to 82.21%. In terms of trading evaluation, give a fantastic return of 121.27% in a year. This evaluation surpassed the results of previous similar studies, even far above the performance of the buy & hold strategy.]]>

<![CDATA[Abstract PT ABCX which is a company engaged in the loading and unloading of containers has an E-Office information system that aims to carry out the company's internal operational activities. So far, the company does not know the factors that influence the acceptance and use of the ABCX E-Office information system, therefore a measurement of the level of acceptance and use of the ABCX E-Office information system will be carried out in supporting the performance of employees in each work unit using the UTAUT methodology. The data in this study were analyzed using SPSS software and the research model was tested with the Structural Equation Modeling (SEM) application which will be analyzed using AMOS 26 software. The results of this study indicate that interest in utilization (BI) is significantly influenced by business expectations (EE) and social influence (SI) while usage behavior (UB) is significantly influenced by interest in utilization (BI). It can be concluded that employees who use the ABCX E-Office information system find it easiest to use and easy to understand and there is also influence and support from the company so that PT ABCX employees are interested in using the ABCX E-Office information system.]]>

<![CDATA[Stock investment is one of the right choices to get more profit. However, in investing in stocks, it is necessary to analyze the data of a company that can determine the rise or fall of a stock price in the company. Very dynamic movements require data modeling to predict stock prices in order to get a high level of accuracy. An algorithm was developed to solve the problem of long-term data or historical data, namely Long Short Term Memory (LSTM). By using the Long Short Term (LSTM) this study produces a fairly good RMSE value with an increase in the RMSE value based on the addition of the number of epoch variations. The optimal epoch variation was obtained with the number of epochs of 200. Meanwhile, the optimal RMSE value produced by the Long Short Term Memory (LSTM) method was generated by TINS issuers with an RMSE of 31.71.]]>

<![CDATA[The rapid development of technology is aligned with the development of web-based applications and it also increases security attacks and various threat techniques that attack the web. The integrated service office at the XYZ local government has used the website to help one of its business processes. That way, a vulnerability assessment, and penetration testing are needed to find out the security gaps on the website. Vulnerability Assessment is a method to search for existing security vulnerabilities on a website and penetration testing is a method to test security vulnerabilities on a website. In this study, vulnerability assessment and penetration testing will be carried out on the integrated service site at the XYZ regional government using the PTES standard with several tools used, namely OWASP ZAP, Acunetix, and Paros on Kali Linux. The vulnerability assessment results obtained on the integrated service website have different types of vulnerabilities and levels of risk according to the tools used. In the tests carried out on the OWASP ZAP tool, the vulnerability with a high-risk level of 10% was obtained. The Acunetix tool got a high-risk level of 16.6%, and the Paros tool got a vulnerability with a high-risk level of 20%.]]>

<![CDATA[Programming teachers very often assess their students' submissions solely from their correctness, sometimes with the help of an automated-grading platform. This approach is arguably effective and efficient at the same time. Unfortunately, this single-dimension assessment approach narrows the students' perspective on a high-quality solution to just a working solution. In the real world setting, a solution should be maintainable with minimal cost. Maintainability is closely related to code quality. In this paper, we present a web-based tool that would help the teachers to assess the students' submissions from both correctness and quality in one place. In this tool, we integrate GitHub Classroom and SonarQube.]]>
