Abstract

The existing tourism recommender system model is mostly predictive analytics for destination recommendations (item recommendation). Limited research has been conducted in the discussion of a recommender system model, particularly context suggestion. Thus, it is necessary to develop a recommender system model not only to predict tourism destinations but also to suggest contexts appropriate for tourist preferences (context suggestions). A deep learning method was used to create a model of the socio-user context aware-based recommender system for context suggestions. The attribute used as a label to suggest context was uHijos, uCuisine, uAmbience, and uTransport. The accuracy of the socio-user context aware-based recommender system in suggesting the context of uHijos, uAmbience, and uTransport was 100% with an error rate of 0%. It was found that only the level of recognition of the model in suggesting uCuisine was less accurate (below 30%) with a classification error for more than 70%. Performance evaluation of the socio-user model context-based recommender system was considered efficient, particularly for the evaluation of the level of accuracy, completeness (recall/sensitivity), precision, and a harmonic average of precision and recall (F-score), mainly for label/context of uHijos, uAmbience, and uTransport.

Abstract

Initially, A smart city was originally a solution used to deal with the environmental crisis that tookplace in the 20th century. Smart city concepts derive from the use of technology and knowledge toenhance society's efficiency and competitiveness. The indicators are needed that support theachievement of a smart city. We will analyze the indicators that can impact the smart cityachievement in this article. The aim of this study is to identify the indicators that influence theprocess of developing a smart city in order to be able to help other cities to establish sustainablepolicies and work plans so that they can prepare themselves for a smart city consistently. From theresults of content analysis and descriptions of literature reviews, it is concluded that the indicatorsmost used in the assessment of smart cities are divided into eight groups of indicators, includinggovernance, economy, living, mobility, environment, people, branding, and demography.

Abstract

Password is important information to access or enter a system. Alphanumeric is a text-based password system that is commonly used. Unfortunately, many users make a weak password that is easy to guess and vulnerable to various attacks such as brute-force, dictionary attack, guessing attack and others. To create a strong password is suggested to have a lot of variety and long, but it will be difficult to remember by the user. Graphical password is an alternative method that gives usability for the user. Based on psychological research, people are generally easy to remember or recognize an images, shapes and colors rather than text. This reinforces the researchers to develop this method. The main problem of graphical password isvulnerable to shoulder surfing. In this paper will be proposed scheme as graphical password text based that are resistant to shoulder surfing attacks using color.

Abstract

Universitas Janabadra (UJB) Yogyakarta, merupakan salah satu perguruan tinggi swasta tertua di kota Yogyakarta. UJB memiliki website yang memuat kegiatan yang berhubungan dengan bidang akademik UJB. Namun, sebagian dosen serta mahasiswa UJB tidak mengaksesnya dikarenakan tidak ada integrasi dengan elemen akademik seperti e-learning, e-journal, digital library, serta informasi pusat studi, yang secara otomatis menghambat kinerja dosen dalam melakukan pendidikan, penelitian, serta pengabdian kepada masyarakat, serta tampilan website yang monoton dan membingungkan sehingga tidak nyaman dilihat serta dikunjungi. Responden yang diteliti yaitu mahasiswa, dosen, serta pegawai pada empat fakultas yang terkait dalam penggunaan website dengan metode purposive sampling. Penelitian dilakukan dengan metode kuantitatif. Untuk pengumpulan data digunakan instrumen kuesioner dengan skala likert 5 poin. Analisis data menggunakan Structural Equation Modelling (SEM) dengan bantuan software aplikasi SmartPLS. Hasil dari penelitian ini menunjukkan bahwa pengujian selama proses desain adalah cara efektif untuk membangun website yang tidak hanya mencerminkan kebutuhan serta preferensi pengguna, tetapi dapat dengan mudah diubah sebagai sumber daya baru kemunculan teknologi. Sebelum proses redesign pada aspek perspektif, sebagian besar reponden berpendapat bahwa tampilan website buruk. Dari segi pemenuhan, kelengkapan informasi UJB dalam website masih kurang. Pada aspek instruksi, website tidak memiliki informasi maupun konten tertentu yang menjadi penghubung antara pengunjung serta pengelola website. Dari segi batasan, tidak ada informasi mengenai batasan informasi yang disampaikan. Untuk aspek assistance, pemberian saran serta kritik sulit karena tidak adanya konten mendukung. Aspek usability, menu fitur dapat digunakan dengan mudah. Setelah proses redesign, perbaikan website UJB sangat baik. Hal ini terbukti dari jawaban responden. Sebagian besar responden berpendapat website UJB telah menyajikan berita lengkap serta update.
