Abstract

Artificial intelligence (Artificial Intelligence) is a system that adopts knowledge from experts into an expert system, so that the computer can do as it is done by experts (experts) who act and can assist in providing solutions and making knowledge-based decisions appropriately. Expert systems are computer-based systems that use knowledge, facts, and reasoning techniques in solving problems, and usually can only be solved by an expert in a particular field. The expert system adds value to technology to help doctors diagnose diseases and provide information about the types of diseases, as well as general symptoms of mediastinal tumors.Mediastinum tumors are tumors found in the mediastinum, namely the imaginary cavity between the left and right lungs, the mediastinum contains the heart, large blood vessels, trachea, thymus, lymph nodes and connective tissue. The mediastinum is an important part of the thorax which is located between the pleuralist cavita and contains many important organs and vital structures. The mediastinum is divided into 4 chambers, namely anterior (front), middle, and posterior (back) superior and medial. Implementing the dempster-shafer method in the expert system it aims to diagnose web-based mediastinal tumor in humans based on the symptoms of mediastinal tumor. From the results of this study, it can be concluded that the expert system of diagnosing mediastinal tumors in humans is expected to help doctors (experts) in providing accurate and accurate diagnosis, so that patients know what disease they are suffering from.

Abstract

Observing everyday life in society seems to be not only an educational, economic, and cultural factor which is a big problem for people today. It turns out that social factors related to the level of well-being, and public health are far more important issues to pay attention to. Because as we all know that the level of living welfare greatly impacts on the health level of the community itself. The choice of the problem concerning the type of Pyelonephritis in the human kidney as a sample of this study, is the fact that the kidney is an important organ in our body's metabolic system, because of the density of activities, we often forget to look after it. Irregular eating patterns, lack of fiber intake and mineral water, and consumption of high-calorie instant foods or drinks, have unwittingly made the kidneys work harder. In general, many people are reluctant or reluctant to see a doctor when they feel the symptoms experienced or also influenced by the absence of fees for consulting a doctor or the limitations of doctors in a particular area, causing handling of patient consultations less effectively and efficiently. So by relying on advancements in technology and information, it is very important to apply expert systems to diagnose diseases in the kidneys. This expert system was created for processing consultation data on pyelonephritis in the kidneys which can be done digitally, so that time is more effective, efficient and helps to deal with patients who are faster consulted. To produce a more accurate expert system, a supporting method is needed, namely fuzzy mamdani method

Abstract

A daily freelance worker is someone who works alone and is not committed to a certain long-term business owner. Temporary daily workers also have obligations that must be fulfilled as something that must be done if the day laborer wants to get his salary, by doing work with a large target without taking into account working hours, this is the only obligation that must be done because casual daily laborers do not bound to a permanent work agreement where usually in the permanent employment agreement the worker must obey every regulation set by the business owner both the company and individual business. Permanent employees are someone who works with the conditions made by the company in work and all work activities have been arranged and the payroll process is carried out with the basic salary set by the company monthly. So from that the plantations of PT. Nafasindo make an assessment in choosing daily burh employees to become permanent employees by making decisions based on the judgments made in the field. thus the need for decision making such as a computerized decision support system so that decision making can be done quickly and accurately. thus this decision support system uses a profile matching or profile matching method which will be used between a fixed profile and a casual day laborer profile with a review process on the criteria that will be set to fulfill permanent employment.

Abstract

Database records in the form of text are very widely used, so it is very vulnerable to data theft by unauthorized parties. In order to maintain the security of database records, it can be done by using cryptographic techniques. Cryptographic techniques can encode database records by encrypting them in the form of passwords that are not understood. The Mars algorithm is an algorithm that uses a 128-bit key and the encryption process consists of 32 rounds. This symmetry algorithm will produce a higher level of security against the database record because it can encode it into a password with a fairly complex process that will make it difficult for cryptanalysts to access the image. This research uses the Mars Algorithm for the encryption and decryption process, so that in the process it is necessary to go through several long steps in order to produce the final cipher. This research describes the process of securing a database record by encoding it based on the Mars algorithm, in the form of a password that is difficult for others to understand and understand. This is done in an effort to minimize acts of misuse of database records

Abstract

Data or files have a very important role for every person who uses computers every day. Sending data or files over a network or media is just another large size, so it takes a long time also requires a large storage space in the process. File submission also requires certainty so that the file sent cannot be stolen or changed by an irresponsible person, so we need a way to overcome these problems. Compression technique is one technique to reduce the large capacity of a file that is used by the file provider in order to secure a file. The process of compressing and supplying PDF files is done by using compressing the data first with the Variable Length Binary Encoding algorithm, then the application designed will carry out these processes so that it will produce compressed and encoded files.
