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.

Abstract

The performance measure of a service cannot be in form and does not result in ownership. Service itself is a form of activity carried out by one or more people, and also is agility (intangible and affected by previous sales). So the services purchased by customers cannot be counted, measured or stored to determine the quality of their services. One of the shoe sales industries is Toko XYZ, this shoe store is one of the largest brands in the archipelago. The prices offered on the national and international market are quite cheap. In order to improve a strategy so that many consumers visit XYZ shoe stores, and for XYZ it is possible to achieve the expected targets with integrated marketing. Data collection in this study consists of 2 steps, namely preparation, this stage is carried out before conducting research such as looking for references on the internet, theoretical foundations that support research such as SCOR model theory and journals. Furthermore, with the contents of the questionnaire compiled to represent the dimensions of service performance quality. The conclusion of the study is that the statement attributes expected by the customer through the SCOR Model method are positive.

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.
