Abstract

At this time electrical energy is needed in terms of helping humans in carrying out their activities both in doing their daily work. In this case, it is impossible for there to be problems in periodic blackouts to save electricity resources carried out by PLN and to disrupt all human activities starting from the tools that require electrical energy. For this reason, it is necessary to anticipate by making an inverter which aims to make all the activities they do using electrical energy are not disturbed. This tool is assisted by using Arduino Uno as the main ingredient which later DC electrical energy, namely the battery, will convert electrical energy that we usually use AC electrical energy

Abstract

The Midwifery Academy (AKBID) is one of the options for continuing post-graduate education, especially in the city of Medan. A quality private midwifery academy greatly influences the course of an education. To easily compete in the world of work. Because a good AKBID has a good accreditation, AKBID accreditation is very influential in the world of work. Especially in the career path, acceptance of new workers. Determining the IMR in the city of Medan is not easy, because there are many IMRs in the city of Medan. There are too many IMRs available, making it difficult to determine the IMR manually, and the election results are sometimes inaccurate and become a problem in determining the best IMR. Decision Support System (DSS) is a system that can assist a person in making accurate and targeted decisions. The method used in the Decision Support System is to use Multi-Attributive Border Approximation Area Comparison (MABAC). This method was chosen because it can assist the decision-making process determining the optimal midwifery academy, in this case the intended alternative is the one who has the right to become the best Midwifery Academy based on the specified criteria.

Abstract

The implementation of education in Vocational High School can not be separated from the important role of a Head of Department, especially in vocational education that becomes his area of expertise. The head of the department has many important tasks related to his field of youth. The determination of the head of the department at SMK Negeri 1 Perbaungan is carried out annually, in which the candidates are assessed in their entirety by the principal and then determined a head of the department who is fit to be the head of the department in that period. To get better results in determining the head of the department can use the Decision Support System as an application that helps the principal in determining the head of the department. A suitable method used based on this case is a combination of Entropy and Extended Promethee II methods in which it can compare between one alternative and another based on each criteria value. Weighting also uses entropy method so that the weight value generated from each alternative value can be more accurate. The resulting exprom II method presents the best candidates to be the head of the department

Abstract

The development of the digital world era continues to grow and is increasing. Many industries have switched to digital technology such as photos, videos, music, and so on. Of course, this change brings many benefits in terms of speed and data access. Ease of accessing the internet also has a major impact on human life. The ease of accessing documents online is very helpful if you want to find and download pdf documents online. With this convenience, many of the same pdf files are downloaded more than once. This will definitely burden the storage space. To distinguish one pdf file from another, it is done by viewing and reading the contents of the pdf file. This is very inconvenient and time consuming. To overcome this, we need a practical way that can be used to search for the same pdf document so that it can delete duplicate pdf files. One way that can be used to overcome this problem is to use a hash function. The hash function in cryptography is a very important tool in various cryptographic applications, for example in digital signature formation, authentication, and so on. Since the discovery of the MD4 hash algorithm by Ron Rivest, many other hash algorithms have been developed based on the principles of this algorithm. One of them is the RIPEMD-128 algorithm. RIPEMD-128 is an iterative hash function that operates on 32-bit words. By using a hash function, the identity of the pdf file can be generated. If the pdf files are the same it will produce the same hash value as well. This will make it easier to group the same pdf documents so that it will speed up the process of deleting the same pdf files. With the pdf file scanner application, pdf files will be searched for all folders and will group pdf files based on the same hash value. So that it will be easier for users to delete the same pdf file.

Abstract

Along with the rapid development of Information Technology and its wide application to various aspects or fields of business, information technology has also been widely used by industry or other organizations. Its utilization aims to facilitate users and provide efficiency in a business field in carrying out its activities. The situation of the coronavirus pandemic demands that we optimally not come into contact with other people or keep our distance. From the facts, many companies or offices still carry out manual receptions using receptionist services which will result in guests having to change their identities to get office access, and the high level of information technology facilities and infrastructure is not matched by the awareness of the Indonesian people to use them optimally. From these problems, the researcher proposes research as an alternative solution in the form of designing web and Android application systems to replace the receptionist function or what is called Digital Receptionist using a structured approach, Design Method, PHP, and MYSQL with web and android based application development. The results achieved are expected to be able to avoid touching hands or keep a distance and increase the efficiency and effectiveness of the guest reception process. The conclusion obtained is that with this Digital Receptionist system, besides being able to increase the efficiency and effectiveness of the guest reception process and avoid touching hands or keeping a distance

Abstract

Globalization can cause several problems and pressures of mind for both individuals and groups. Various kinds of problems can certainly lead to psychological disorders, one of which is depression. Indonesia itself is one of the countries with a high number of people with depressive disorders. Depressive disorder itself can have many consequences ranging from lack of enthusiasm to even death. Facing these serious problems, the government should be able to address the mental disorder that is currently happening. However, the reality is still far from this. Inadequate infrastructure, equality problems for each region, and shortages of experts are the main problems at this time. The expert system is considered to be a solution in solving these problems. Web-based expert systems can replace the role of experts in the process of initial diagnosis of depressive disorders, patients can also access them easily. The calculation method implemented is the Certainty Factor method. This method is considered suitable in the diagnosis of depression. The implementation of the CF method in the diagnosis of depression can provide a confidence level of up to 94.9%. The expert system is expected to be able to eliminate human errors, speed up the diagnostic process, make it easier for health workers, and provide standards for related parties in handling mental disorders

Abstract

The login data record in the database is a table that stores a number of data related to the username and password. The information contained in the username and password data certainly cannot be accessed arbitrarily by others, because the data is confidential. The discussion that will be carried out in this research is to conduct an analysis of the Rivest Code 2 key generation which is then modified by combining the method of generating the Not-Micali Generator (BM-G) key. The results of the modification process for Rivest Code 2 key generation, then testing the Rivest Code 2 algorithm for activities to increase the value of confusion for data records in the database
