<![CDATA[The growth of the online retail market in Indonesia is an excellent business opportunity. It is predicted that this growth will continue to move upward due to the increasing internet penetration. With greater exposure to brands, products and offerings, consumers become smarter and wiser in their purchasing decisions. Offering goods and services that match the tastes and behavior of consumers is very important to maintain business continuity. So far, the models developed are divided into two major parts, namely the time series approach and machine learning. In this study, segmentation and forecasting of online retail sector sales were carried out using extreme gradient boosting (XGBoost). The data used in this study is an online retail dataset obtained from the UCI repository. The k-means clustering (KMC) method is applied to determine the target or data class. Principal component analysis (PCA) is applied to reduce data dimensions by eliminating irrelevant features. Model evaluation is based on confusion matrix and macro average ROC curve. Based on the research results, XGBoost can perform retail data classification well, this can be seen through confusion matrix metrics and ROC curves.]]>

<![CDATA[Natural Language Processing (NLP) is part of artificial intelligence which focuses on natural language processing. That is the language commonly used by humans in communicating with each other. In writing, articles can also be applied. To find out the similarity of the contents of a scientific article to another will make it easier for readers to make selections and make it easier to collect similar documents. Likewise with differences in article content even though they use the same keywords. Measurements are made using the keywords contained in the abstract which consists of several words and the number of keywords. The method used is to use fuzzy string matching to get the number of keywords used in an article. Then the calculation will be done for each keyword used and will be sorted by priority according to the position of the keyword. The search will be carried out starting from the title, abstract, keywords, content, and references. The number of keywords found in each article is shared across all keywords found to generate a similarity percentage level. If the results found are the same in number from one article to another, it can even be categorized that the contents of the article have similar content. The testing process is carried out by counting the number of keywords in the source then comparing all the source keys to the destination articles in the database by searching and comparing each word.]]>

<![CDATA[Air quality in a room is a problem that needs to be considered because it can affect human health. Therefore, we need a system that can monitor LPG, CO2, and cigarette smoke levels to determine the value of air quality levels in a room. Air pollution levels can be measured with the MQ-2 sensor to detect levels and an Android-based application as an information viewer. This study aims to build a monitoring application for LPG, CO2, and cigarette smoke levels based on the wireless ESP8266 sensor network in the room. The level monitoring application is built with the Java programming language, Firebase, and Arduino software. The application development stage includes analysis, system design, implementation, and testing. The level monitoring application that is made can display the results of monitoring data. So those users can find out the measurement data of a level that is in a room with a series of sensors used. The result is research on the use of this device can be used as a tool to monitor air quality in a room.]]>

<![CDATA[Di tengah pertumbuhan ekonomi yang begitu baik, masih ada perusahaan kontruksi yang masih menyusun laporan arus kas secara manual, dimana semua penerimaan dan pengeluaran kas hanya dicatat dalam buku kas dan perhitungannya dilakukan menggunakan aplikasi Microsoft Excel sedangkan pengolahan datanya menggunakan aplikasi Microsoft Word, sementara ilmu komputer sudah sangat maju yang telah memiliki sistem berbasis komputer untuk mempermudah pencatatan arus kas. Pada perusahaan, kegiatan Oprasionalnya antara lain adalah menjual jasa kepada pelanggannya. Kegiatan ini akan mengakibatkan terjadinya uang masuk untuk pendapatan aliran uang keluar untuk biaya. Kegiatan investasi merupakan kegiatan membeli atau kembali investasi pada surat berharga jangka panjang dan aktiva tetap. Jika perusahaan membeli investasi/aktiva tetap akan mengakibatkan arus kas keluar dan jika menjual investasi/aktiva tetap akan mengakibatkan adanya arus kas masuk ke perusahaan. Kegiatan keuangan atau kegiatan pendanaan adalah kegiatan menarik uang dari kreditur jangka panjang dan dari pemilik serta pengembalian uang kepada pemilik. Tujuan dari penelitian adalah untuk membuat sistem informasi penerimaan dan pengeluaran kas pada PT.
