Share it is an application made by Lenovo which is a service for sharing various types of files, for example images, videos, applications or others.share it, which is currently widely used, has many functions that can help someone when sending and receiving files. One of them is sending files via the Webshare feature in the Share It application. Usability testing is a series of processes or activities that involve Respondents to find out how well a product (system) can be used easily by Respondents. This study discusses how easily Respondents send files via the Webshare feature in the Share It application. The method used here is Thinking-Aloud. The results obtained in this study are respondents who find it difficult when searching for Webshare features in the Share It application. We also provide advice on how to fix this problem with some references that we encountered on the internet.

Analisis Data Time Series Menggunakan LSTM (Long Short Term Memory) Dan ARIMA (Autocorrelation Integrated Moving Average) Dalam Bahasa Python. Adhitio Satyo Bayangkari Karno

Abstract — This study aims to predict time series data by using two methods, the first method commonly used is statistics Autocorrelation Integrated Moving Average (ARIMA model) and the second method which is relatively new, namely machine learning Long Short Term Memory (LSTM). Before the data is processed by both methods, data cleaning and data optimization are carried out. Data optimization is a transformation process to eliminate elements of trends and variations from data. The transformation consists of 7 results of a combination from Log processes, Moving Average (MA), Exponential Weigh Moving Average (EWMA), and Differencing (Diff). The seven processes are each used in the ARIMA and LSTM processes. So that 14 predictions will be obtained (7 from the ARIMA process and 7 from the LSTM process). From the 14 prediction results obtained the smallest RMSE value for ARIMA is 2% and the smallest RMSE value for LSTM is 1%. The results of this study using 7 combinations of transformation processes, can increase the level of accuracy of predictions from ARIMA and LSTM. Where the accuracy of LSTM learning machines by using Telkom's stock data has higher accuracy than ARIMA.

The Primary Tax Service Office has used technology in delivering information about taxes, such as the existence of an official tax portal service site as a forum for delivering information about requirements, announcements and provisions related to taxes for the general public. In addition, there are also online applications that are under the auspices of the Directorate General of Taxation which serve as services related to online tax reporting for the general public. However, the Primary Tax Service Office does not yet have a service to provide services to users quickly, easily and can be used at any time, therefore a chatbot application is created that can answer tax-related questions that can be accessed at any time easily and quickly. This chatbot is built using the hypertext preprocessor programming language and database using MySQL and the Artificial Intelligence Markup Language which contains a collection of patterns and responses that can be used by chatbots to search answers to each sentence. The software development methodology used is the Rapid Application Development (RAD) method. This research produces a chatbot application that can help users by answering questions about taxes.

SaaS application users get strategic benefits, among them the speed of implementation, reliability, and flexibility also optimization of infrastructure capacity. The company does integration with the aim to increase productivity, data accuracy, speed and flexibility [1]. This also drives XYZ.com, an online store in Jakarta, to integrate its web commerce application with SaaS accounting application. System integration design is carried out by analysis and observation of current business processes using the business objectives model. It is concluded that with system integration, XYZ.com wants to achieve 3 business objectives, i.e. (1) increasing the number of orders recorded in the accounting application, (2) improving stock accuracy, and (3) reducing the number of order cancellations due to unavailability of goods. System integration is designed to enable information retrieval such as products, contacts, transactions, and journals from accounting application through available API. Further research needs to be carried to realize the list of requirements that have been described in the feature tree to the stage of software development and implementation so that the objectives set by the business can be measured and improved.
