<![CDATA[The internet is one proof that information technology is growing. The use of the internet today is increasingly showing trend a positive One of the impacts felt in the development of information technology is a non-departmental government agency of the Central Bureau of Statistics (BPS). BPS is a non-departmental government agency in Indonesia whose main function is to provide statistical data and information. Included in the document analysis results of the BPS data needs survey in 2020, which concludes that consumers in the BPS Integrated Statistics Service (PST) tend to use services that provide data and statistical information in digital or softcopy. This trend is also reinforced by the percentage of the main facility to obtain the largest BPS data is website (41.88%). Therefore, the Kuningan Regency BPS needs to optimize the media for disseminating statistical data and information, one form of innovation that can be done is making an android-based publication application. The application is named Kuningan Dalam Angka Statistik (KUDAMAS). In the development of this application software the prototype and the functionality test uses black box testing. Based on the results of the tests carried out using Black Box testing, the results obtained were successful for all testing of each feature in the application and it can be concluded that the KUDAMAS application has been running according to its function]]>

<![CDATA[Human resources in a company organization are very important to support the progress and quality of the company in achieving its goals. One of the keys to the success of an organization is employees, who have an important role in an organization, therefore human resource management in an organization is carried out properly in order to be able to achieve the shared goals of the organization. The administrative process for employee data that is currently running at Madrasah Istiqlal Jakarta is still being done manually, one of which is applying for employee leave. This manual system has many shortcomings, namely the use of a long time, incomplete reports required, and more prone to errors. The process of collecting personnel data manually will cause the available data to be incomplete or missing and take a long time. Therefore, a personnel information system is needed to overcome these problems. A good Personnel System will produce precise and accurate data so that it greatly influences the course of decision making. The waterfall method has a high speed of adaptation, can be made quickly and also because the waterfall method is suitable for software products whose needs are clear at the beginning, so there are minimal errors. The result of this research is a personnel information system that can assist employees in receiving information with an integrated database]]>

<![CDATA[Indonesia is one of the countries with the potential of large earthquakes because it is passed by three active plates, namely Indo-Australian, Eurasian, and Pacific. Earthquake information is currently still in text form, so the blind have difficulty getting earthquake information. It is needed to develop the earthquake information applications from text to sound. The source of earthquake information is taken from an XML file that has been provided by BMKG. The application development uses the Waterfall method. The testing uses a blackbox with the boundary value analysis. The results of this study is text to speech application for earthquake information. Application testing using blackbox with the boundary value analysis for six different scenarios were successfully 100% running well without any errors]]>

<![CDATA[The ease of accessing the internet makes it very easy for humans to share various kinds of files. These files are very easy to download, so it is not uncommon for these files to become duplicates or the same files are stored on personal storage media. This of course will take up personal storage space owned. To avoid this, the steps that can be taken are to provide the identity of each file that represents the contents of the file. So that it can be known whether the contents of the file are the same or not. To generate the identity of a file, a special algorithm is needed that can represent the contents of the file. Algorithms that can be used to generate file identities are algorithms that fall into the hash function category. But in its development there are many algorithms in hash functions that can be used to generate file identities. The algorithms that are often used are the MD5 algorithm and the SHA-256 algorithm. The MD5 and SHA-256 algorithms have different algorithm structures so they have different performance when generating the identity of a file. By comparing the performance between the MD5 and SHA-256 algorithms, we will get an algorithm that has better performance when used to generate file identities.]]>

<![CDATA[Determining suppliers is important to support company performance, because determining the wrong supplier can cause harm to the company. Then the Analytical Hierarchy Process method is considered appropriate and appropriate for research related to problems in determining or selecting suppliers. By determining the right and optimal supplier using this AHP method, the company can select and evaluate suppliers so that the company can determine the appropriate criteria and alternative suppliers. Then the results are obtained that Arasari is considered the most appropriate to be a supplier with the highest weight gain priority of 0.427 or 42.7%, the second Lavanda Brownies of 0.291 or 29.1% and the third is Durian Orchid of 0.282 or 28.2%. While the results obtained through calculations using expert choice, explained that Arasari remained in first place with a value of 45.9% then Lavanda Brownies with a value of 29.7% and there was only a slight difference with Durian Orchid who obtained a percentage value of 24 4%. So based on these results, it can be seen that there is no difference in the order of global priorities for the total ranking goals obtained between manual data processing with the help of expert choice]]>

<![CDATA[The government's policy in suppressing the transmission of COVID-19 is to limit people's mobility. The policy called Pemberlakukan Pembatasan Kegiatan Masyarakat (PPKM) with different levels for each district or city. The COVID-19 pandemic has not ended so far, so we need a method that can assist government in suppressing the spread of COVID-19 by classifying PPKM level policies in districts or cities that are adjusted according to the assessment level of each districts or cities. This study aims to classify PPKM levels with the fuzzy rough set method approach. The determination of the PPKM level policy based on epidemiological parameters, namely the number of positive cases of Covid-19 for 100,000 population, number of cases treated for 100,000 population and number of deaths for 100,000 population. The study began by inputting the COVID-19 spread dataset, pre-processing the data, and classified the data using the fuzzy rough set method. The stages of the fuzzy rough set method began with transforming the data into fuzzy form in the form of a table called an information system and partitioning the set of objects based on the similarity of the attributes contained in the decision system table into disjoint subsets according to 3 decision class labels, namely level 1, level 2 and level 3. The output rules consist of certain rules where the degree of fuzzy membership in the fuzzy equivalence class is the future effectiveness for each certain rules, and possible rules. Classification with fuzzy rough set approach obtains output of 58 rules consisting of 6 certain rules and 52 possible rules. The classification results show that PPKM level policies can be classified using the fuzzy rough set approach]]>

<![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]]>
