Therefore came the idea of centralized data storage that can be modified to accommodate the availability, scalability, reliability, and management of data. One way that can be done is to apply Distribute Database using Sharding Horizontal Partition technique and experimental methods using mariadb and spider engine. The test was carried out on the database of food processing sites (TPP) in the TPP application at the ministry of health. The test results prove that although in some journals about Sharding, more sharding is implemented on NoSQL DBMS such as MongoDB, influx dB. In this study it can be proven that sharding can also be done in relational DBMS such as MariaDB and MySQL, data can be distribute and load process too, test result successful although the performance of time query response is still better single database than distribute database.","PeriodicalId":378682,"journal":{"name":"JURNAL SISFOTEK GLOBAL","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121661789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system built and upgraded will provide troops with an overview of modern Holomatrix-based simulations. By using a computer that is able to evoke a three-dimensional atmosphere so that it can display as if it were a physical 3D image. The modern Holomatrix-based simulation will be used to train Tactical Decision Making Procedures (PPKT) and subordinate commanders to map and model yudha so that they can provide an overview of the actual operating field. After testing, it was found that this simulation application can be used as a tactical training tool, where each military branch involved can coordinate properly as it is done in real combat.","PeriodicalId":378682,"journal":{"name":"JURNAL SISFOTEK GLOBAL","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121062109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on data from the health department, the city of Tangerang said that the level of transmission of Covid-19 in the Tangerang Raya area was included in the red zone category, where the spread of Covid-19 averaged 130 additional cases per day. The main problem found is the difficulty of detecting early symptoms that arise as an indication of being infected with Covid-19 and tools to assist in detecting early symptoms felt by the general public. In this study, a rule-based knowledge representation process for the initial clinical symptoms of Covid-19 infection was carried out using an expert system with the certainty factor method, which aims to measure the level of certainty that has been confirmed by Covid-19 against the initial clinical symptoms felt by the user and makes it easier for users to detect the early symptoms of Covid-19 and helps the government, in this case, the health service center through the availability of the expert system application. Based on the results and discussions that have been carried out in this study, it can be concluded that the results of experiments to detect early clinical symptoms that were implemented using an expert system with the certainty factor method showed empirical calculations in the range of 81-85% confidence level on the results given by the system in initial clinical symptoms entered by the user. The results of the research above were obtained through a process of validating the suitability of initial clinical symptoms to the level of Covid-19 infection by using the forward chaining method and then measuring the level of confidence in the results that have been given based on the established rules. The expert system application with the proposed certainty factor method is the basis for developing mobile-based applications that can be used easily for the wider community","PeriodicalId":378682,"journal":{"name":"JURNAL SISFOTEK GLOBAL","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126723570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this research was to determining the information such as public sentiment on social media towards government policies in handling COVID-19. In this research, 2000 tweets were used. The keyword used related to government policies are sourced from several online media. The tools used to analyze this twitter data is using Orange Application. The selected keywords are covid19, lockdown, PSBB, and isolation. This keyword is used as a reference to retrieve tweet data from twitter. From each of these keywords, a sentiment classification process will be carried out automatically so that data or tweets are obtained and grouped into positive, negative and neutral sentiment classes.

In recent years, there have been several cases involving data security, such as the leaking of Facebook user account information. This is certainly a significant issue in the world of information technology and even the world of entrepreneurship because it involves one of the young entrepreneurs, Mark Zuckerberg. Main problem in this case is data security. who can know information and who should not know information. To overcome such things, research is made in the field of data and information security by analyzing one of the encryption and decryption techniques, namely RC4 cryptography. This study explains how RC4 cryptography works, the advantages and disadvantages of RC4 cryptography, and the effectiveness of RC4 cryptography. RC4 (River Ciper 4) is a decryption encryption technique that uses a key as a reference. The process consists of KSA, PRGA, and XOR. To find out the usefulness of RC4 cryptography, in this study, encryption and decryption were carried out on text data. There are several advantages and disadvantages to RC4 cryptography from a technical point of view. The advantage that needs to be underlined is that this RC4 cryptography uses a certain key as a reference, things like this can provide convenience to the encryption maker but can also be a threat. as a result RC4 can hide information very well while the secret key is not known by others. In addition to being used in text data, this cryptography may be used for other data such as audio and video.","PeriodicalId":378682,"journal":{"name":"JURNAL SISFOTEK GLOBAL","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125245339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The services are provided throughout the year, thus requiring infrastructure support and adequate information systems that can run24 hours a day. To maintain and ensure the continuity of Hajj and Umrah services, a Disaster Recovery Plan is designed, which is used as a guide in dealing with disasters or disturbances that can occur at any time and can disrupt all operational activities of the organization. In this study, the NIST 800-34 framework is used, starting with risk identification and assessment, Business Impact Analysis (BIA), preventive controls identification, contingency strategies, and contingency plans. The contingency plan preparation phase includes the activation phase, the recovery phase, and the reconstitution phase. Based on the result of research, there are ten risks that can threaten the continuity of information system services and based on Business Analysis Impact, services with a high critical level are Siskohat and Haji Pintar applications.
