Abstract

Attendance record is very important because it can measure the level of someone’s dicipline. Any formal environments definitely use this method to monitor attendance. There are various methods of doing attendance, such as by biometric systems (fingerprint) or through by system. At the beginning, PT BPR Dana Makmur employee’s do attendance with a fingerprint machine. However the presence of coronavirus (Covid-19) caused changes of the attendance method in PT BPR Dana Makmur because the virus can be transmitted through fingerprint. From this problem, researchers tried to develop a web-based presence system to replace fingerprint methods. This application is expected to minimize the spread of the virus at PT BPR Dana Makmur or other company environtment.

Abstract

Weather is part of carrying out an activity and affects several fields, such as determining crops in agriculture and aviation on departure in an airplane. Android is an operating system that can be used and is open source code, android can develop and modify easily. The Meteorogy, Climatology and Geophysics Agency (BMKG) is tasked with monitoring the weather that predicts the weather using two methods, namely conventional methods and statistical methods which can cover a radius of 5-10 km on land and 50 km at sea for observations in a predicted area. The problem in this study is that the weather diagnosis requires a complex database, so a method for accurate weather diagnosis is needed and weather diagnosis information is very difficult to obtain. Forward chaining is a technique that starts the search for data and facts, and the data is used as a conclusion to become a solution. So the forward chaining method can help make diagnoses related to the weather. The purpose of diagnosing weather changes is to be able to help the special community in the Riau Islands to help plan activities. Researchers are designed to be able to assist the surrounding community in obtaining weather diagnosis information by providing complete information and accurate results but carried out efficiently. Keywords: Weather, Android, Forward Chaining, BMKG

Abstract

Security is an important aspect of an information system. Many people do not know how to secure files that are created or received or do not know how to protect files that are created or received so that there is no theft of files that cause information from those files to leak. Every organization, industry, or infrastructure, needs a level of network security solution to protect against the growing hacker threats in today's world. Text files that contain information in text form. Data originating from word processing documents, numbers used in calculations, names and addresses in the database are examples of text data input consisting of characters, numbers and punctuation marks. Input and output text data is represented as a character set or code system recognized by the computer system. Cryptography is a science that studies how to keep data safe when sent, from sender to receiver without experiencing interference from third parties. Vigenere Cipher is method of encrypting alphabetic text using letter and numbers. This table is usually referred to as the Vigenere Table. The concept of cryptography itself has long been used by humans, for example in the Egyptian and Roman civilizations, although it is still very simple.
