<![CDATA[Technology for document management is really need because it can improve performance both in storage, search and document security. Document management in a manual way can waste time in finding required documents and requiring a lot of space for hardcopy document storage. This study uses a string matching algorithm combined with ROT13 algorithm. String matching algorithm is used to find a file name in database, the file name in database has been encrypted for example plaintext “Kabel Ladder” into chipertext “Xnory Ynqqre”. The steps of string matching algorithm combined with ROT13 algorithm in this study are, word pattern is encrypted and then matched with existing data in database and then a string search in performed using string matching algorithm and produces the data sought. In both algorithm, time and number of matches were tested between pattern and data to show performance of two algorithms using 200 data until 500 data. The result of testing 200 data for search word Tower takes 0.00513 sec and matches 65x, 300 data for search word Tower takes 0.00716 sec and matches 164x, 400 data for search word Tower takes 0.01372 sec and matches 262x and 500 data for search word Tower takes 0.02233 sec and matches 360x. From the test result in this study, the researchers concluded that string matching algorithm combined with ROT13 algoritm, the more data, more time it will take, even though it is still relatively small]]>

<![CDATA[Water is one of the sources of life in this world. The benefits of water are of course incalculable, if we relate it to the consumption of water, especially mineral water. Many companies see the business potential of mineral water as a very profitable potential for businessmen. But with the emergence of many brands of drinking water in containers creating very strong competition between companies, this makes it difficult for mineral water consumers to choose which brand to buy, it is necessary to review the mineral water brand that is sold and consumed the most. From these problems, it shows that the importance of a Decision Support System to help buyers of mineral water brand products in determining the choice of brand of goods that is in line with the criteria. The method used in this decision support system research is the WASPAS method. The ranking results of each alternative using the WASPAS method with the final result of the Aqua brand product occupying the first position with a value of 2,441 as a recommendation for the selection of bottled mineral water product brands, and the Club product brand having a value of 2,219 by placing the last of 7 alternative brands of bottled mineral water products. . From these results, it can be concluded that the mineral water brand AQUA is the best choice to increase its stock because it has the highest value of 2,441.]]>

<![CDATA[The development of information technology has made the popularity of social media increase in recent years, one of which is Youtube. Youtube’s popularity make this platform a major source of sentiment where almost everyone tends to express their views in the form of comments. These commnent not only express people but also have more meaning about their experiences. Comments originating from social media are unstructured so that in sentiment analysis the preprocessing stage is an important task. There are many techniques used in preprocessing including stopwrod and stemming. However, several studies have shown that the use of stopword and stemming gives different result. Therefore, in this paper, the researcher further anlyzes the effect of applying stopword and stemming on Youtube video comment regarding the New Normal policy using Long Short Term-Memory. The result obtained we found that the use of stopword and stemming greatly affects the performance of the model, this is because a lot of information is lost after the stopword process and some words change meaning after stemming.]]>

<![CDATA[Classical cryptography is the science of securing secret messages (plaintext) into disguised messages (ciphertext) in which each character is changed. The process of converting plaintext into ciphertext is called encryption, while the reverse process is called decryption. However, this classical crypto algorithm can still be solved using the Kasiski method, due to the mathematically regular pattern of repeating keywords. Therefore, in order not to be easily solved, another method is needed, namely by modifying the Caesar Cipher and Vigenere Cipher cryptographic algorithms. Therefore, to strengthen the security of the classical cryptography algorithm, it is necessary to carry out a modification process using an algorithm that is able to change the complexity of the encoding by using a randomization algorithm. By including a randomization algorithm, it is considered that it can eliminate the possibility of attackers guessing the results by knowing the algorithm used. The randomization algorithm used is the Blum-Micali Generator algorithm. The purpose of using the Blum-Micali Generator algorithm is that the encryption process is randomized so that the encryption results obtained are more difficult to guess, making it difficult for cryptanalysts to read the message or information]]>

<![CDATA[Message applications have now become a part of today's society. Beside from features, security and privacy are important things for users. Security and privacy are important because some users of this application are worried if the message their send will misused by the company. This concern is heightened after a new rule issued by a popular instant messaging application company where data from the messaging application will be linked to other applications for business purposes, some popular messenger users are worried about their privacy choosing to switch to other messaging applications that are considered more secure and offers privacy. One of the applications of choice is Signal Messenger becouse this application is more secure in maintaining privacy. This is a concern if applications that offer more privacy become a means to commit crimes. Consider that, the research work will focused on conducting forensic testing and analysis of the Android-based Signal Messenger application. The test will carried out on SMA530F and RedmiNote 4 smartphone devices. The scenario that will applied is by installing the Signal Messenger application on each smartphone, then communication between the two smartphones is such as sending text messages, images, and videos. From these activities, the mobile forensics stage using the NIST method such as making acquisitions and then analysis to obtain digital evidence. The test results will be expect for a reference for the authorities and related parties if there is a case using the Signal Messenger application and it is hoped that this research can add to the literature in the field of digital forensics, especially mobile forensics]]>
