<![CDATA[Nowadays, Today, crime using smartphones is increasingly massive. Prevention efforts are carried out using mobile device forensics. In this study, a test was conducted to obtain deleted WhatsApp data using Autopsy with a combined method of ISO 27037 and NIST SP 800-101 R1. The type of data that you want to get is a list of contacts, call history, text messages, pictures, videos, audio, documents, and locations; while the total data used in this study amounted to 67 data. The results of the tests that have been carried out, Autopsy was able to obtain a quantity index of 87.5% in terms of obtaining the type of data; while in terms of getting all the data, Autopsy obtained a quantity index of 95%.]]>

<![CDATA[This study aims to create a tool to increase the energy absorption of arduino uno-based solar panels to generate current, voltage, and radiation intensity data that will be used to monitor solar power plants automatically using the Waterfall method. Connecting the sensor with the arduino uno, the design of the arduino uno-based solar panel works well in detecting the temperature and humidity of the room. The results of the PIR Sensor Range Angle are carried out horizontally to the sensor and the distance is also varied from 1 m to 7 m. The test results of the DHT11 Sensor were tested for accuracy of measurements using a humidity comparison/thermometer type k Lutron HT-3006HA which has the ability to measure temperature and humidity. The data obtained is calculated the value of 0% error. LDR sensor testing is done by exposing the sensor directly to the state of natural light in the room from time to time with normal weather conditions. Where all detected ADC values are above 500 so the lights are on.]]>

<![CDATA[The development of information has penetrated into the digital realm, by utilizing computer technology as an information technology tool in an organization or company will provide added value to the data processing process. The process of data processing in the form of incoming and outgoing letters at PT. Telkom Access is still done conventionally as well as manual archiving, with higher correspondence intensity and demands for speed and punctuality. In this study, we will develop a website-based e-mail management system display using the CodeIgniter3 framework and Bootstrap with the scrum methodology. It is hoped that by developing the appearance of the system, it can make it easier and more comfortable for users to use the system.]]>

<![CDATA[Libraries have another form called digital libraries. In line with the development of information technology that has entered human life, it has brought changes to the library system. The desire to have library resources that can be accessed anywhere and anytime also encourages the existence of digital libraries. By utilizing a digital library-based information system, everyone can obtain appropriate and useful reading sources. The impracticality of the conventional library system is that one has to go to the location first, which is very impractical. This situation makes digital libraries one of the solutions that can be built to bridge these weaknesses. The method used in this study is a qualitative descriptive method. From the results and discussion obtained the steps for creating an account, digital library design, how the system works, and the appearance of digital libraries. The hope of this research is that the library system created can be used by anyone to support an easy, inexpensive, and paperless information system.]]>

<![CDATA[In the business of selling goods, there must be goods that do not sell well and sell well. How to make unsold items sell well by giving customers a discount or discount strategy. The goal is to provide discounted prices to attract customers' attention and increase sales turnover. Prediction to give the right discount presentation is needed in the discount strategy. How to determine discount prediction using linear regression method, looking for line equations by training data taken from Kaggle.com. The data were trained to find the constants and coefficients of the independent variables. The resulting line equation will be tested to determine the discount prediction that will be given and calculate the error value. The data used is painting sales data taken from Kaggle.com, a total dataset of 1525, and a prediction calculation is made with 225 lines of test data. The input variable used is the price of the painting, and the output variable is the discount presentation. The process of evaluating the prediction results by calculating the MAE value, the difference between the actual data and the predicted data, the MAE value from the trial is 0.108.]]>

<![CDATA[The mouth is the entrance to the digestive system and contains accessory organs that are in the early stages of digestion, while teeth are made of a very hard material, namely dentin. (Indah Irma & Ayu Intan, 2013. Many people complain of pain in the teeth and mouth due to lack of hygiene in maintaining the health of this organ. So when people are attacked by dental and oral diseases, people try to do their own treatment, for example buying toothache medicine in the shop. According to Turban (in Vincent, 2011) an expert system is a system that uses human knowledge where this knowledge is entered into a computer and then used to solve problems that usually require human expertise or expertise. The method used is the forward chaining method, namely forward chaining starting from a set of facts (there are) by looking for rules that match the assumptions/hypotheses that exist towards conclusions (Siswanto 2010).]]>

<![CDATA[This study aims to build a library system application that can be used in the library of the Faculty of Engineering UNTAG Semarang based on an RFID card. From the background of the problem, namely, the process of borrowing and returning books is quite long, because to search for borrowed books the librarian must go to the bookshelf and look for the title of the book to be borrowed. The difficulty in making reports, because it is done after the library activities are finished, does not automatically coincide with the process of borrowing and returning services. Starting from the problems above, and paying attention to the number of daily visitors in the library that must be served, the authors propose to create a library service application using an RFID tag that can help the process of searching for member data and library books quickly.]]>
