Data Center Risks Analysis Through The COBIT Framework 4.1
Get PDFInformation Technology Governance in UIN Jakarta is the responsibility of the Pusat Teknologi Informasi dan Pangkalan Data (Pustipanda). Some troubles have occurred in the data center Pustipanda, among others the loss of courses and its values that have been inputted in the application of Academic Information System (AIS), loss of data that has been inputted on the application Beban Kinerja Dosen (BKD), damage data content on the portal in the environment UIN Jakarta. Risk analysis is needed to identify and anticipate and minimize risks which may occur. In this research, the risk analysis is using the COBIT 4.1 framework that is in the PO9 process (Manage and Assess IT Risk) as input towards PO9 is the domain of PO1, PO10, DS2, DS4, DS5, ME1, and ME4. Questionnaires which were distributed to respondents were developed from input variables. Respondents were chosen by purposive sampling method. The results of the questionnaire were recapitulated and calculated the value and degree of capability. The result of this research is the level of domain capability in data center Pustipanda is at level 2 (managed) with value 1.91. A fairly low value is obtained on DS4, DS5 and ME1 domains, which are 1.67, 1.88 and 0.67. Arosen risks from the majority of data center risk assessment were the absence of documented policies and procedure and lack of training for risk management measures at Pustipanda data center

Devices from this data logging system was created using arduino uno r3 with adding ethernet shield modul and temperature sensor DHT 11. in iot devices, there is an important parameter, that is date time as a history in data logging sistem using an actual time. Website was functioned as system for showing data from log data and could be monitored realtime. This system could record communication brtween arduino device and NTP server using internet network. Beside that?this system could record important parameters in the system such as IP source address, ip destination address, ip address in each node, device time, and room temperature information. Parameters that had been recorded would be stored to database, then would be showed in web data logging
Finding Nearest Mosque Using Haversine Formula on Android Platform
Get PDFPrayer is the second pillar of Islam, emphasized after the two sentences of syahadat. It\u27s regarded as perfect worship. Obligatory for both Mukimin and Musafir, its virtue in the mosque equals 20 degrees of reward compared to elsewhere. However, amidst increasing traffic jams, travelers often face difficulty finding the nearest mosque for Maghrib prayer. This problem can be addressed by finding the shortest path from the starting point to the destination. To tackle this issue, a research was conducted to design an application providing directions to the nearest mosque in the Larangan area of Tangerang city. The system utilizes the haversine formula and Java programming language for implementation. Java builds the application, MySQL database stores data, and Google Maps API determines the route.Prayer is the second pillar of Islam and it is emphasized after the two sentences of syahadat. It has been said that it’s as perfect and as good as worship. Prayer is one of the obligations for Muslims and must be done both for Mukimin and Musafir. The virtue of prayer in the mosque is the same as the value of 20 degrees of reward compared to prayer elsewhere. With the traffic jam phenomenon that is increasing due to heavy traffic. For someone who is traveling home in the afternoon before maghrib, some people are always confused to do Maghrib prayer because of the lack of information about the nearest mosque. The problem can be solved by finding the shortest path is a problem to find the minimum route from the starting point to the destination point with the shortest route. This research was made to design an application that provides direction to the nearest mosque in the area of Larangan, Tangerang city. In the making of this system to find the shortest path can be solved using the haversine formula and using the java programming language, where java is used to build applications while the database used is the MySQL database and the use of Google Maps API in determining the route
Development of National Digital Evidence Metadata
Get PDFThe industrial era 4.0 has caused tremendous disruption in many sectors of life. The rapid development of information and communication technology has made the global industrial world undergo a revolution. The act of cyber-crime in Indonesia that utilizes computer equipment, mobile phones are increasingly increasing. The information in a file whose contents are explained about files is called metadata. The evidence items for cyber cases are divided into two types, namely physical evidence, and digital evidence. Physical evidence and digital evidence have different characteristics, the concept will very likely cause problems when applied to digital evidence. The management of national digital evidence that is associated with continued metadata is mostly carried out by researchers. Considering the importance of national digital evidence management solutions in the cyber-crime investigation process the research focused on identifying and modeling correlations with the digital image metadata security approach. Correlation analysis reads metadata characteristics, namely document files, sounds and digital evidence correlation analysis using standard file maker parameters, size, file type and time combined with digital image metadata. nationally designed the highest level of security is needed. Security-enhancing solutions can be encrypted against digital image metadata (EXIF). Read EXIF Metadata in the original digital image based on the EXIF 2.3 Standard ID Tag, then encrypt and insert it into the last line. The description process will return EXIF decryption results in the header image. This can secure EXIF Metadata information without changing the image qualit
Implementation of Finding Shortest Route for Pharmacy Location Using A-star Algorithm
No full textThe number of pharmacies in the Pangkalpinang City has increased rapidly. This is directly proportional to the needs of the people of Pangkalpinang City to fulfill the health needs, buy medicine or divert doctor\u27s prescriptions. This is a debate for people who do not know the location of pharmacies in this city. Practically, people can just go to a pharmacy with a location that far from user location, even though there is a pharmacy near the user. This is because there is no pharmacy information location in the Pangkalpinang City. To solve this problem, proposed a system that can display the location of all pharmacies in the Pangkalpinang City. In addition, the system can search the shortest path from the user\u27s location to the nearest pharmacy location around using the A * algorithm. This algorithm was chosen because its advantages that are able to produce optimal solutions according to the expected heuristic functions. The results of the testing are that the system can optimize and be able to search the shortest path from the user\u27s location to the nearest pharmacy
Implementation SHA512 Hash Function And Boyer-Moore String Matching Algorithm For Jpeg/exif Message Digest Compilation
Get PDFSecurity information method for JPEG/exif documents generally aims to prevent security attacks by protecting
documents with password and watermark. Both methods cannot be used to determine the condition of data integrity at the detection stage of the information security cycle. Message Digest is the essence of a file that has a function as a digital fingerprint to represent data integrity. This study aims to compile digital fingerprints to detect changes that occurred in JPEG / exif documents in information security. The research phase consists of five stages. The first stage, identification of the JPEG / exif document structure conducted using the Boyer-Moore string matching algorithm to find JPEG/exif segments location. The Second stage is segment content acquisition, conducted based on segment location and length obtained. The Third step, computing message digest for each segment using SHA512 hash function. Fourth stage, JPEG / exif document modification experiments to identified affected segments. The fifth stage is selecting and combining the hash value of the segment into the message digest. The obtained result shows the message digest for JPEG/exif documents composed of three hash values. The SOI segment hash value used to detect modifications for JPEG to png conversion and image editing. The APP1 hash value used to detect metadata editing. The SOF0 hash values use to detect modification for image recoloring, cropping and resizing — the combination from three hash values as JPEG/exif’s message digest
