"[Pengetahuan tentang elemen-elemen yang dapat meningkatkan pengalaman pengguna (user experience/UX) ketika menggunakan sistem operasi merupakan hal yang penting. Hal ini dibutuhkan bagi pengembang sistem operasi untuk membangun sistem operasi yang baik dari segi fungsi atau kegunaan (usability), dan juga dari segi pengaruh tampilannya (affect). Pendekatan yang digunakan dalam penelitian ini untuk mendapatkan elemen atau indikator tersebut adalah dengan melakukan pemodelan (PLS-SEM). Dimana hingga saat ini pendekatan UX secara kuantitatif, khususnya pemodelan, masih sedikit. Penelitian dilakukan dengan memberi tugas-tugas tertentu terkait dengan aplikasi Windows 10 Technical Preview (sebagai representasi) kepada subjek penelitian. Hasil penelitian menunjukkan bahwa pada masa orientasi, pengaruh tampilan (affect) secara subjektif merupakan hal yang lebih penting dari kegunaan (usability) objektif untuk meningkatkan penilaian pengguna (user value) dan pengalaman pengguna secara keseluruhan (overall UX). Lalu, dari masing-masing elemen UX yang terdiri dari usability, affect, dan user value tersebut, didapatkan indikator-indikator yang dapat menjadi prioritas dalam membangun sebuah sistem operasi. Sebagai tambahan, dilakukan retrospective think aloud untuk mendapatkan umpan balik pengguna, Knowledge about elements that can improve user experience when using an operating system is important. It is needed by operating system developer to build the operating system that is good from its usability, and also from its display affect. Approach that is used in this research to get the element or indicator is by doing the modeling (PLS-SEM). Whereas until this day quantitave UX approach, especially modeling, is little. The research is did by giving particular tasks about Windows 10 Technical Preview applications (as representation) to research subject. Research result shows that in orientation state, subjective affect from display is more important than objective usability to increase user value and overall user experience. Then, from each UX elements that are usability, affect, and user value, it is obtained each indicators that can become priority when building up operating system. As an addition, retrospective think aloud is conducted to get feedback from user.]"

"Parkir Meter adalah salah satu alternatif pemerintah DKI Jakarta untuk memperbaiki manajemen parkir. Namun masih ditemui sejumlah masalah usability dalam penggunaan mesin sehingga menyebabkan ketidakpuasan pengguna. Masalah usability berkaitan erat dengan user interface karena user interface adalah bagian paling penting pada mesin yang bisa dilihat dan disentuh oleh pengguna. Penelitian ini dilakukan untuk mengevaluasi dan melakukan perancangan ulang user interface mesin parkir meter Jakarta. Metode yang digunakan untuk mengevaluasi adalah dengan metode usability testing. Hasil yang didapat dari penelitian ini adalah tingkat usability mesin parkir meter masih sangat rendah dan hasil perancangan ulang user interface terbukti lebih efektif, efisien dan meningkatkan kepuasan pengguna. ......Parking Meter is one of the alternative that taken by Jakarta government to improve parking management. But a number of usability problems still encountered when using parking meter which lead to user dissatisfaction. Usability problems closely related to the user interface since the user interface is the most important part of the machine that can be seen and touched by the user. This study was conducted to evaluate and redesigning user interface of Jakarta parking meter machine. Usability testing methodology is used to evaluate parking meter. The results of this study are the level of usability parking meter machine is still very low and the results of redesign user interface proved to be more effective, efficient and improve user satisfaction."

"Product packaging is not only used as a product container, but also used as a means of marketing by companies, particularly by those involved in consumer goods. Yogurt products are predicted to experience expansion in the Indonesian market. In this study, the authors analyzed the implementation of cognitive-based design in developing yogurt product packaging to increase consumers’ willingness to buy the product. This study was divided into two phases: initial research and primary research. Initial research pursued six levels of color scheme and font factors and then narrowed down the results into the two best options that would later be combined with the primary research that analysed the shape factors. Research methods used in the initial study were the Eye-Tracking method and the ‘Retrospective-Think-Aloud’ (RTA) method. Preliminary results showed that ‘Fineliner’ and ‘Bodoni’ font type along with ‘Analogue’ and ‘Tetradic’ color schemes are judged to be the best combination and thus, these results would be combined in the main study with the shape factor. Conjoint Analysis methods were used in the main study. The main results of the research study showed a preference from Indonesian consumers for yogurt product packaging with the ‘Fineline’ font type with its rounded shape and an ‘Analogue’ color scheme."

"Pengguna Motion Banking menghadapi masalah dan tantangan dalam aspek UI/UX aplikasi seperti penulisan dalam aplikasi tidak tertata dengan baik, detail tidak memadai, dan navigasi yang membingungkan. Tujuan dari penelitian ini adalah untuk mengevaluasi pengalaman pengguna aplikasi Motion Banking dan menghasilkan rekomendasi perbaikan desain sesuai hasil evaluasi. Metodologi yang digunakan dalam mengevaluasi pengalaman pengguna adalah dengan melakukan usability testing. Evaluasi didasarkan pada metrik kinerja dalam bentuk task success, time on task, time-based efficiency, dan error. Metrik yang dilaporkan sendiri adalah pertanyaan kemudahan tunggal dan skala kegunaan sistem. Dengan metrik berbasis isu dalam bentuk restrospective think-aloud. Responden kesulitan menyelesaikan tugas dalam data metrik kinerja, terutama untuk tugas 2, 3, dan 4. Temuan single ease question (SEQ) hasilnya menunjukkan antarmuka sulit digunakan oleh responden pada tugas 2, 3, 4, 5, dan 6. System usability scale (SUS) dengan nilai 52,75. Saran peningkatan desain mengikuti prinsip ergonomi kognitif, khususnya "Laws of UX" dan "8 Golden Rules." Temuan evaluasi untuk Meningkatkan desain antarmuka mengungkapkan bahwa nilai metrik untuk semua tugas telah meningkat dengan skor SEQ dan SUS keseluruhan masing-masing menjadi 6,7 dan 86.......Users of Motion Banking are facing problems and issues in the UI/UX aspect of the application such as the writing in the app is not well organized, details are inadequate, and confusing navigation. The purpose of this study is to evaluate the user experience of the Motion Banking application and produce recommendations for improvement designs according to the evaluation results. The methodology that is used in evaluating the user experience is by conducting a usability study. The evaluation is based on performance metrics in the form of task success, time on task, time-based efficiency, and error. The self-reported metrics are single ease question and system usability scale. With the issue-based metrics in the form of retrospective think-aloud. Respondents had trouble completing tasks in the performance metrics data, particularly for tasks 2, 3, and 4. 3. the single ease question (SEQ) findings the results show the interface is difficult to use by their respondents on tasks 2, 3, 4, 5, and 6. the system usability scale (SUS) with the value of 52.75. The design enhancement suggestions follow cognitive ergonomics principles, particularly the "Law of UX" and "8 Golden Rules." The evaluation findings for Improve interface design revealed that metrics values for all tasks had improved with the overall SEQ and SUS scores being 6.7 and 86 respectively."
