<![CDATA[Technology has entered any field and has an important role to make every work process faster and more efficient. Thus, the admin application web system and radio advertisement recording are needed to assist in the process of recording, printing and depositing radio advertisements. This research application web system will be created using the Laravel framework and the PHP programming language. Laravel is a php-based web application framework that uses easy-to-understand models, views and controllers. The prototype method is a method that will provide an initial picture or concept as an experimental design that can make it easier for researchers to find out how the system can run well.]]>

<![CDATA[The era of globalization as it is today, the development of technology is growing so rapidly.However, this is not coupled with the technology in the water storage tank in the mosque that still uses manual water measurement, which results in the end of wudu water without realizing it so that the congregation has difficulty wudu water. After seeing the problem, then designed a tool to determine the water level in the water tank that can determine the amount of water volume in the water storage tank and can provide a warning in the form of an alarm. The results of testing the water level detector on the ablution water storage tank at ulil albab mosque based on this microcontroller are able to work well, this water measurement uses ultrasonic sensors. and is able to display the indicator of the amount of water volume, then the buzzer will sound when the water in the storage tankimmediately runs out.]]>

<![CDATA[The use of electronic media is expected to help the archive managers to manage their archives effectively and efficiently. By using electronic media in the management of Archives will be obtained the benefits of speed, convenience and savings. The purpose of speed here is through the use of electronic media, the process of searching, discovering, distributing and processing data is carried out in a short time. The purpose of the ease of use of electronic media is the ease in terms of search, distribution and processing of data, which is efficient in the use of electronic media that can reduce energy, mind and save costs in managing archives. With these reasons, at present many organizations / agencies that use electronic media in the management of archives, ranging from simple to sophisticated. At the Forestry Service of North Sumatera Provinceexperience difficulties in the management of receiving and storing various letters, reports, forms and so on.

<![CDATA[Android is an operating system that is widely used in this modern era. This is inseparable from Android features that are increasingly being developed to facilitate the user experience. Along with these developments, security problems also arise when exchanging information or data. Security is an important aspect of the development of modern information technology era, so the development of the branch of science that studies data security or known as cryptography. This study aims to design and build a secure chat application based on Android and implement the XOR algorithm. This algorithm is used to secure information so that it cannot be read before it reaches the recipient. The calculation of this algorithm generates a random message (ciphertext) that can only be read by the recipient. The result of this search is a chat application in which there is a security feature where the recipient must enter the same key as the sender in order for the message to be read. Testing of this application is done by sending a message then entering the same key between sender and receiver.]]>

<![CDATA[WFZ Book Store is a Book Store that provides various types of books. The sales process is done offline where the costumer has to visit the store to make a purchase. The process of recording data using the ledger makes it difficult for WFZ Book Store to make sales reports because it has to collect transaction data in the ledger, it causes difficulties to know the available Book stock because it has to check every sales transaction in the ledger. WFZ Book Store requires an information system that can manage book sales data onlineagarcostumers can easily view book data, stockand book online reservations. With the wfz Book Store information system can facilitate the customer in managing book data and store customer data that has made transactions also WFZ Book Store does not find it difficult to provide book purchase transaction data for the customer, so that the data can be used for book recommendations by finding the set of data that most often appear in a data set. Datamining techniques have been widely used to overcome existing problems, one of which is the application of a-priori algorithms to find association rules formed from book purchase transaction datasets. So it will be known the association between the title of the book purchased. The association rules between book titles formed from the mining process can later be used by the WFZ Book Store to increase the number of books purchased, besides that it can be used for the procurement of books from the association rules of frequently purchased books, it can also be developed into a knowledge base for the book purchase recommendation system. The Output is in the form of a priori algorithm analysis software.]]>

<![CDATA[Diseases of the teeth and mouth are one of the many health problems that often interfere with the activities of sufferers. Diseases attack indiscriminately Reed both children and adults. Dental and oral health is an important thing that needs to be considered. Problems that occur in the teeth and mouth must be handled properly so as not to cause other problems that occur due to improper handling. Doctors are required to provide decisions quickly, and accurately in diagnosing diseases suffered by their patients. But to make such a diagnosis is not easy, considering that each disease has more than one symptom, and several different diseases have almost the same symptoms. Decision - making in diagnosing the disease carefully and appropriately must be done quickly for the treatment process of the disease. Especially for young doctors and all doctors if they find cases that are difficult to diagnose, they will generally be guided by books. This will certainly take time and effort. Treatment for this problem is to build an expert system application that functions to diagnose diseases of the teeth and mouth. This expert system application is expected to help doctors in deciding to diagnose diseases quickly or become a matter of consideration or reference.]]>

<![CDATA[The rapid development of technology at this time, educators are expected to be able to create interesting and innovative learning media for students. So that it has an impact on student learning outcomes later. One of the learning media that can be utilized is the TikTok application. The TikTok application is an application in the form of short videos that are packaged properly. And the majority of users are millennials and school children. The purpose of this study was to determine the effectiveness of TikTok-based learning media used in informatics class X TKJ at SMK Negeri 2 Padang. The method used is an experiment. By using One Group Pretest-Posttest Design. The sample is determined by simple random sampling technique. For data analysis techniques using the analysis prerequisite test, namely the normality test, hypothesis testing using the paired sample test with a result of 0.000, and the N-Gain test. Based on the results of the N-Gain test in the experimental class, it was obtained at 63,765 or 63.7%. In the interpretation of the N-Gain percentage category if 56-75% is said to be quite effective. So the N-Gain score of 63.7% is said to be quite effective. So that the effectiveness of TikTok-based learning media in class X TKJ informatics subjects at SMK Negeri 2 Padang is quite effective.]]>
