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.

The development of technology is an inseparable part of human life. Through its development, technology furthermore produces various reliable tools to assist people in many ways. The technological applications can be in the forms of Google products such as Google Classroom, Google Form, and Google meet, and also other applications such as Zoom Cloud Meeting, Microsoft Teams intended to solve various kinds of problems including education field. These technological advancements are popularly used and are indeed very helpful in learning, but sometimes it can’t be hindered that technological applications are not always in accordance with the needs. For example, the practicum learning process in the Information Systems Study Program, Faculty of Science and Technology, Open University, which has no practical application yet. This is because the existing applications are not in accordance with the learning process at the Open University. So, the solution that must be done is to develop an online practicum application (Praton) in the Information Systems Study Program, Faculty of Science and Technology of the Open University. The process of developing a practicum application also cannot be done immediately, so at least there must be an application development design first. Application development design must go through several stages using a software development model. One of the models that can be used is the waterfall model with an object-based approach or commonly referred to as UML (Unified Modeling Language). The results of this software development design are in the form of a software design document and will be sent to a programmer to establish the application. With this application design, programmers will know more about the specifications of online practicum applications that suit the needs of learning process.

The Open University is a State University prioritizing independent learning. Independent learning would certainly succeed if the students owned a strong determination in effectively and efficiently manage their time. In the Information Systems Study Program curriculum, there are several practical courses that must be conducted offline. In 2019 however, the phenomenon of the COVID-19 pandemic outbreak requiring all educational units to carry out learning from home had impacted on the learning process, especially the implementation of practicum at the Open University. The implementation of practicum activities usually held in collaboration with several institutions has become constrained. This triggered the possibility of not achieving student learning outcomes related to learning materials learned through practicum. Therefore, as an alternative solution, an application is required that could assist the students in carrying out practicum learning activities independently which is adapted to each teaching material. This practical application would be developed in a study using the Waterfall method consisting of analysis, design, implementation, testing and maintenance. From the results of test using the System Usability Scale (SUS), the score obtained is 64.44 (margin low). This means that the application online practicum can be used but does not meet the requirements to be implemented into existing learning systems until it gets a score of more than 80 (Acceptable).

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.
