Abstract

The implementation of credit transfer at Universitas Terbuka refers to the Rector's Regulation Number 119, 2018. This credit transfer could only be carried out once when students registered themselves at very first time. Recognition of credit transfer is accepted whn accomplishment of courses have been obtained from their previous universities. Through the provision of credit transfer recognition services, students are expected to be able to finish their study faster. Students can apply for credit transfer through the Faculty which would then be proceed by Study Program. Students are required to collect documents such as diplomas, transcripts, descriptions of courses at their previous university, and the submissions for courses intended to be transferred for credit. The documents which are in form of print out would later be processed in their respective Study Programs. During the process, the Study Program compiled the documents manually by recording and determining the courses approved for credit transfer. However, the study Program hasn’t used a special application. Due to this limitation, several problems occurred in the process, such as the absence of filing the credit transfer application documents, the ineffectiveness of storing the credit transfer master block in the Study Program, and the large number of credit transfer applications. These problems often result in delays in the credit transfer process, thus disrupting academic services for students. Therefore, it is necessary to develop a credit transfer application that can assist in the implementation of credit transfer in the Faculty of Science and Technology. The methodology used to develop this credit transfer application is the waterfall model. For design modeling using UML (Unified Modeling Language), while software testing uses Black Box Testing and usability and acceptance tests applied the PSSUQ (Post-Study System Usability Questionnaire) method. From the results of the tests, it showed that Black Box Testing got test results of 100%, while the usability and acceptance tests using the PSSUQ method got 68% of respondents. The conclusion of this study showed that the application is ready to use and the users Agree/Good/Like on the development of a web-based credit transfer application at the Faculty of Science and Technology of the Universitas Terbuka (case study of Information Systems Study Program). Kata kunci: Credit transfer, Web, Waterfall, , Black Box Testing, PSSUQ.

Abstract

Artificial Neural Network (ANN) can be applied to recognice pattern, particularly at the stage of data classification. This study used a multilayer perceptron backpropagation ANN, an unsupervised learning algorithm, to recognize the pattern of uppercase handwriting on the answer sheet of multiple-choice exams. The application of this network involves mapping a set of input against a reference set of outputs. In this research, ANN was trained using 8000 handwritten uppercase characters (A, B, C, and D) consisting of 6000 training data characters (1500 characters for each letter) and 2000 testing data characters (500 characters for each letter). The result showed that for the most optimal performance, the architecture and network parameters were 10 neurons in hidden layer, learning rate of 0.1 and 3000 iteration times. The accuracies of the result using the optimal network architecture and parameters were 90.28% for training data and 87.35% for testing data.

Abstract

The web Application For Information Systems And Transactions For Teaching Materials (SITTA) is an application that is used to support operational activities in the distribution service of teaching materials at State Universities of the Open University. The SITTA web application can be accessed on the https://distributions.ut.ac.id/ website with internal access to UT at the center and UPBJJ (Distance Learning Program Unit). The SITTA web application was used by UT employees as users of the SITTA web application, which was used recently because the SITTA web application was only implemented in early 2018. Therefore, it was deemed necessary to test its usability. This is to assess the success of the usability aspect of an information system application while at the same time knowing that the application can be useful and has been by its function or not for user needs. One of the tests that can be done is usability testing. This test is carried out using the USE Questionnaire method using 4 aspects of testing. 4 aspects tested are aspects of Usefulness, Satisfaction, and Ease of Use. The purpose of this paper is to determine user acceptance of the SITTA web application based on usability criteria. This research is a quantitative descriptive type that is carried out on users of the SITTA web application by distributing a USE Questionnaire consisting of 30 questions and using 5 points of assessment on a Likert Scale. This study obtained the results of measuring the usability of the SITTA web application with a score of 88.10% on the measurement of the usefulness aspect, 78.29% on the ease of use, 82.14% on the ease of learning, and 81.26% on the satisfaction aspect. satisfaction.

Abstract

Suatu aplikasi sistem informasi perlu diuji untuk mengetahui apakah aplikasi tersebut berjalan dengan baik dan sesuai dengan kebutuhan user. Salah satu uji aplikasi adalah uji kegunaan (usability testing). Universitas Terbuka memiliki sebuah sistem yaitu Sistem Informasi Tiras dan Transaksi Bahan Ajar (SITTA) yang dikelola untuk memberikan pelayanan dan pendistribusian bahan ajar ke mahasiswa. Aplikasi SITTA yang digunakan yaitu berupa layanan berbasis website. Website SITTA belum pernah dilakukan usability testing sebelumnya. Oleh karena itu penelitian ini memiliki tujuan untuk melakukan usability testing aplikasi web SITTA dengan menggunakan metode PSSUQ. PSSUQ digunakan sebagai instrumen penelitian yang terdiri dari 19 butir pertanyaan. Metode PSSUQ ini menggunakan aspek usability dengan berfokus pada 4 kategori penilaian dalam konsep usabilty yaitu System Usefulness (Sysuse), Information Quality (InfoQual), dan Interface Quality (InterQual), dan Overall. Penelitian ini bersifat penelitian deskriptif kuantitatif yang dilakukan pada user aplikasi web SITTA sejumlah 140 orang dan menggunakan 5 skala poin penilaian pada Skala Likert. Hasil yang diperoleh dari penelitian ini secara kuantitatif yaitu perolehan nilai rata-rata skor secara keseluruhan pada empat kategori usability pada PSSUQ yaitu sejumlah 1,99. Untuk kategori penilaian Sysuse memperoleh nilai rata-rata terendah yaitu 1,93 dan kategori Interqual memperoleh nilai rata-rata tertinggi yaitu 2,03. Metode PSSUQ mempunyai prinsip lower score high usability, hal itu memiliki arti jika skor yang didapat semakin kecil maka nilai usability-nya semakin besar, sehingga dapat disimpulkan bahwa aplikasi web SITTA dilihat dari aspek kegunaan sistemnya pengguna merasa cukup puas dan aplikasi bermanfaat serta sesuai dengan kebutuhan pengguna.
