Abstract

Goods purchase requisitions and goods issue documents are receipts for purchase requisitions and goods issues for distribution goods from the unit of work to the warehouse. pt. Perkebunan Nusantara V still uses the manual method of registering and approving the Goods Request Form using a form filled out by a factory assistant and signed by multiple parties. Therefore, it takes 5-30 business days to collect all signatures. If all parties are present, the product request notification can be signed and approved immediately. However, if this is not the case, the bill of goods approval process will be delayed. For this reason, urgent needs often result in goods being released from the warehouse before the invoice has been fully approved. Therefore, there is a need for an application that helps companies manage good purchase requisitions from warehouses. The application is implemented as a website that allows users to approve notes step-by-step online. The prototyping method allows developers to design and build systems more efficiently because discussions take place between users and developers during the system development process. PHP Laravel is used as programming language and MySQL as database. The tests for this application are based on the ISO 9126 test standard and give the following results: According to the USE survey, functionality scored 100%, reliability scored A, usability scored 90.07 across the four factors, efficiency scored B, performance score 88%, The structural score was 87%. Maintainability was evaluated as A grade with a debt ratio of 2.6%, and portability was evaluated as 100%. This application reduced the approval time to less than 5 hours and test results showed that the application works well and is suitable for enterprise use

Abstract

The online helpdesk with ticketing system with the help of operators often experiences problems such as inappropriate delegation processes, the duration of the helpdesk waiting time to be delegated, even the helpdesk is missed to be handled. The ticket delegation checked manually by the operator has risks creating an error in delegating helpdesk tickets to inappropriate technicians. The helpdesk classification system is needed so that every incoming helpdesk ticket can be classified to the right technician according to the job description. The incoming Helpdesk is classified into 6 types of requests, namely multimedia, documentation, internet, server, hardware, software and miscellaneous. This helpdesk grouping is needed so that related technicians for each helpdesk can work and help the helpdesk according to their respective job descriptions. The Support Vector Machine method is used to classify text on the helpdesk. The use of Linear and Polynomial kernels produces an accuracy of 78%, the RBF or Gaussian kernel produces the highest accuracy of 81% while the Sigmoid kernel produces the smallest accuracy of 51%. The helpdesk classification results with the Support Vector Machine method can produce quite good accuracy.

Community stigma about mental disorder often leads schizophrenia patients to be too late taken to a health facility. People believed that schizophrenia is caused by mystical things so that the first treatment is brought the patients to alternative medications. The development of a very rapid computer nowadays makes us easily build a web-based expert system. This expert system is trying to find a satisfactory solution as an expert does. The system was developed to diagnose the schizophrenic mental disorder and the diagnosis was done by analyzing the inputs symptoms, in the form of checklists of what people were felt, then choosing the density of its severity. The results of the diagnosis provide an outcome, i.e. the names of the disease along with the possible percentage value generated based on the selected symptoms. This research intended to build an expert system using PHP and MySQL programming language to store its database, while the inference method using forward chaining is the process of tracing that begins by displaying a data set or convincing facts to the final conclusion. This research resulted a diagnosis schizophrenic mental disorder expert system that is capable to early diagnosing schizophrenic disorder, based on the symptoms that have been selected by the user with a simple appearance that is easy to understand and can be accessed by many users.

Abstract

Salah satu bentuk protokol kesehatan yang harus ditaati selama masa pandemi Covid-19 adalah kewajiban memakai masker di tempat umum. Namun kenyataannya masih sering dijumpai anggota masyarakat yang tidak mematuhi aturan tersebut. Mereka hanya mau taat jika ada pengawasan dari Satgas Covid-19. Penelitian ini mengembangkan sebuah prototipe untuk melakukan deteksi masker wajah secara realtime menggunakan algoritma Viola and Jones. Algoritma Viola and Jones terbukti handal dan cepat dalam mendeteksi objek. Prototipe tersebut bekerja dengan mendeteksi area hidung dan mulut. Jika ditemukan area hidung dan mulut di area wajah maka akan disimpulkan bahwa objek tidak memakai masker. Jika tidak ditemukan area hidung dan mulut, maka akan disimpulkan objek memakai masker. Berdasarkan hasil pengujian diketahui bahwa prototipe ini mampu bekerja dengan baik pada pencahayaan yang rendah dan jarak 1 meter.
