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

The Universitas Terbuka (UT) website serves as the primary platform for providing academic services and information to students, lecturers, and the general public. However, as the number of users and the complexity of digital services increase, User Experience (UX) becomes a crucial aspect that influences the effectiveness and user satisfaction in accessing information and utilizing available features. This study aims to evaluate and analyze the user experience of the Universitas Terbuka website using a combined approach, incorporating survey questionnaires and web performance analysis. The urgency of this research lies in the need to ensure that the UT website delivers an optimal experience for its users, particularly in terms of ease of navigation, access speed, information clarity, and responsiveness across different devices. With the growing reliance on digital systems in distance learning, UX evaluation becomes a strategic step in identifying challenges and opportunities for improvement. The novelty of this study lies in its holistic approach, which integrates subjective user feedback from surveys with objective web performance analysis. The findings of this research are expected to provide concrete recommendations for enhancing the UX quality of the Universitas Terbuka website, thereby supporting the effectiveness of distance learning and improving access to academic services.

Abstract

The current of wisma’s Universita Terbuka reservation system still faces various obstacles, especially related to data consistency and integrity anomalies. This problem causes errors in recording and confusion in the transaction process, such as duplication of invoice numbers, which in turn can reduce reporting accuracy. This research aims to design a basis data for the Open University guesthouse reservation system using the Basis data Life Cycle (DBLC) method. This method includes several stages, starting from needs analysis, conceptual, logical, and physical basis data design. The results show a well-structured and optimized basis data design, which supports the management of reservation data, check-in, check-out, and room reservation management. The normalization process to achieve Third Normal (3NF) ensures that the data is free from redundancy and remains consistent. The physical model of the basis data is implemented using SQL queries, which are ready to be applied to a Basis data Management System (DBMS). The designed basis data is expected to improve operational efficiency, record accuracy, and maintain data integrity in the Open University guesthouse reservation system. This research is also expected to contribute to the development of literature on systematic life cycle-based basis data design.

Abstract

Proses pemesanan modul atau Bahan Ajar Cetak (BAC) bagi mahasiswa Universitas Terbuka (UT) sangat bergantung pada ketersediaan stok di Gudang Pusat Layanan Bahan Ajar (PLBA) UT. Prediksi kebutuhan dan jumlah persediaan BAC yang optimal sangat diperlukan agar tidak terjadi kekurangan atau penumpukan akibat stok bahan ajar yang berlebih. Dengan adanya prediksi kebutuhan BAC yang tepat dan akurat, diharapkan dapat membantu proses perhitungan bahan baku yang akan dibeli dapat sesuai dengan jumlah kebutuhan dan pemesanan BAC yang diterima mahasiswa. Sehingga hal tersebut dapat mengurangi resiko kekurangan atau kelebihan stok dalam proses inventori manajemen yang berjalan. Penelitian ini bertujuan untuk menentukan kuantitas persediaan BAC dengan menggunakan sebuh model prediksi safety stock dan reoder point (ROP). Safety stock digunakan untuk mengetahui berapa jumlah aman stok yang harus disediakan dan ROP digunakan untuk mengetahui kapan waktu pemesanan ulang harus dilakukan. Penelitian ini menggunakan metode deksriptif kuantitatif. Sumber data diperoleh secara langsung dari data histori transaksi bahan ajar dalam rentang waktu masa registrasi sebelumnya yaitu semester 2022 genap. Batasan penelitian ini adalah menghitung prediksi kebutuhan untuk stok BAC mahasiswa jenis program Sistem Paket Semester (SIPAS) pembelajaran Non Tatap Muka (Non Ttm) pada program Paramita UT tahun 2023. Hasil prediksi safety stock menunjukkan presentase akurasi tertinggi yaitu 86,84% setelah dibandingkan dengan data riil pengeluaran BAC masa 2022 genap

Abstract

The rapid growth of social media usage has significantly influenced the marketing and development strategies of Micro, Small, and Medium Enterprises (MSMEs). However, there remains a limited understanding of how various users perceive the role of social media in supporting MSME growth. This study aims to segment user perceptions regarding the impact of social media on MSMEs, utilizing the K-Means Clustering method. The research novelty lies in combining perceptual analysis with an unsupervised machine learning technique to discover hidden patterns in public responses. Data were collected through a questionnaire distributed to MSME actors and users of MSME products across Indonesia. The questionnaire includes statements related to the accessibility, promotional effectiveness, and trust-building capability of social media. The clustering results categorize respondents into several perception groups—ranging from highly positive to neutral or skeptical, providing valuable insights for stakeholders and digital marketing strategists in targeting communication and support for MSMEs. This approach offers a data-driven strategy to optimize MSME empowerment through the appropriate use of digital platforms.
