Abstract

A workshop is a building that provides space and equipment for carrying out construction or manufacturing, and repairing objects. The accumulation of customers at Bengkel H. Tomo Service is caused by the lack of workers in the repair process. This is based on not every day customers who come in excessive numbers, but at one time the situation is not crowded enough. Due to this condition, the number of repair workers is reduced so that the workshop owner can adjust between the customer and the worker. From these conditions, the H. Tomo Service Workshop needs to create a system that can predict the number of customers who will come in the following days or months. The prediction results can be used to anticipate the needs of repair workers in the workshop. The process of predicting the number of customers who make vehicle repairs at the workshop can be done with a computerized system, one of the processes that can be done is the application of an Artificial Neural Network (ANN) using the Backpropagation method. The system is designed with the MATLAB R2014a programming application, after carrying out the data training process and data testing on 2016 to 2020 data, the learning rate is 0.2; the maximun epoch is 10000 and the target error is 0.001, the result is that in 2021 the predicted number of customers is 13758 customers who make repairs at the H. Tomo Service workshop.

Abstract

Motor vehicle testing is a series of activities to test and inspect parts on motorized vehicles. Vehicle testing that still uses a manual system makes the testing service process take a long time and there are often delays in vehicle testing. Therefore, a system is needed to simplify and speed up the vehicle testing process. Based on this, this research is intended to create a motor vehicle testing information system that can assist officers in carrying out vehicle testing services. From the results of the research conducted, it greatly increases knowledge and insight, by collecting data relating to the motor vehicle feasibility test. The PHP programming language and MySQL database can be built into a system for testing the feasibility of motorized vehicles using the Certainty Factor method. Based on the data on the motor vehicle assessment criteria, it can be tested for the feasibility of motorized vehicles using the Certainty method. From the results of calculations using the Certainty Factor method and based on the weight of each criterion, it can be analyzed from the calculations that have been carried out with the results of the motor vehicle test passing with a confidence level of 97.10%, conditional passing with a confidence level of 95.84%, and not passing with a level of confidence. confidence 94.75%. Thus, the above vehicle is declared to have passed the kir test with a confidence level of 97.10%.

Abstract

The development of technology in security systems to ensure the confidentiality of data information has grown rapidly. In maintaining the confidentiality of data information, there are sciences in development such as steganography and cryptography. Data and information security is very important in the current reform era. Generally, every institution has important and confidential documents that can only be accessed by certain people. The issue of data security and confidentiality is one of the important aspects of an information delivery system. In this case, it is closely related to how important the information is sent and received by interested people. Information will no longer be useful if in the middle of the delivery process, the information is intercepted or hijacked by unauthorized people. Computer crime is the illegal act of using knowledge of computer technology to commit a crime. Theft of hardware and software (hardware and software), manipulation of data, illegal access to computer systems by telephone, and changing programs

Abstract

Data security is very important in maintaining the confidentiality of information, especially those containing sensitive information whose contents should only be known by the entitled people. especially if the transmission is done through a public network, if the data is not secured beforehand, it will be very easy to be intercepted and the contents of the information known by irresponsible people. One of the methods used to secure data is to use a cryptographic system, namely by providing the information content (plaintext) into content that is not understood through the encryption process, and to retrieve the original information, a description process is carried out, accompanied by using the correct key. Therefore, the author recommends the Elgamal algorithm to be able to provide security for text data. The reason the author uses the ElGamal algorithm is that the ElGamal algorithm is part of asymmetric cryptography where the formation of one of the keys uses prime numbers and focuses on the strength of the key in solving discrete logarithm problems.

Abstract

Registration services for outpatients that are simple and fast are one of the efforts to improve the quality of service to patients who will seek treatment at the hospital. The strategy adopted by the hospital is to utilize information technology to support services, especially the flow of outpatient registration which will later affect patient satisfaction. One of the strategies implemented by hospitals in the current digital era is to implement a computer-based registration system, but in practice there are still many obstacles and the use of the information system is not optimal where there are still many queues and buildup of patients seeking treatment. This study aims to develop an online outpatient booking application that will make it easier for patients to register for outpatient treatment online. This application is expected to make it easy for patients to register outpatient care without having to come directly to the hospital directly. Patients only need to book a polyclinic through the application and check in when they come to the hospital to get a queue number at the intended polyclinic. It is hoped that this application will shorten service time and reduce patient queues.
