Salah satu upaya untuk mengangkat nilai-nilai sosial dalam pemberantasan korupsi adalah dengan membuat aplikasi-aplikasi pemberantasan korupsi seperti laporan pengaduan, suap dan gratifikasi. Tahapan yang dianggap penting dalam merancang sebuah aplikasi dimulai dengan merancang antarmuka pengguna (UI) dan pengalaman pengguna (UX). Pengguna akan melihat desain antarmuka dan cara berinteraksi dengan aplikasi sebagai kesan awal penilaian UI/UX. Metodologi yang digunakan dalam melakukan perancangan adalah metode “design thinking”, metode ini dikenal sebagai proses berpikir komprehensif yang berkonsentrasi pada penciptaan solusi yang diawali dengan proses empati terhadap kebutuhan tertentu yang berpusat pada manusia. Pengujian aplikasi “Ayo BerAksi” dilakukan oleh project manager dan pihak BBKP Belawan yaitu dengan pengujian digital prototyping. Walaupun para pengguna sasaran menganggap bahwa aplikasi “Ayo BerAksi” ini merupakan aplikasi yang sangat bermanfaat dan telah memenuhi kebutuhannya, namun masih memiliki beberapa kendala yang dapat dijadikan sebagai masukan dan perbaikan. Kesimpulan dalam jurnal ini adalah perancangan desain UI/UX menerapkan metode design thinking yang mempunyai beberapa tahapan dimulai dari proses empathize, define, ideate, prototype, dan test yang terstruktur dengan baik.

Hal penting yang harus diperhatikan oleh setiap petugas investigator forensika digital dalam menjalankan aktivitas forensika digital adalah diikutinya setiap tahapan dan prosedur dalam forensika digital. Tahapan tersebut dikenal dengan istilah frameworks ataupun SOP investigasi. Tahapan dalam proses forensika digital harus sesuai dengan aturan hukum dan juga mekanisme yang tepat. Namun framework investigasi yang berkembang saat ini ternyata masih terdapat kekurangan dimana ada tahapan-tahapan yang diatur dalam standar yang berlaku seperti SNI 27037:2014, ternyata tidak diatur dalam framework tersebut. Sehingga ketika tahapan tersebut terlewatkan dalam proses investigasi, tentu akan menjadi sebuah masalah dan bisa digugat di pengadilan serta dibatalkannya hasil investigasi yang dilakukan terkait adanya prosedur yang tidak dilaksanakan. Oleh karena itu dilakukan penelitian dengan melakukan identifikasi terhadap ketentuan dan proses penting dalam dokumen SNI 27037:2014 untuk kemudian menghasilkan instrument evaluasi yang dapat digunakan oleh penyidik atau praktisi forensika digital untuk melakukan penyesuaian atau evaluasi terhadap framework yang digunakan selama ini.

The COVID-19 crisis has profoundly impacted many sectors globally, including education, necessitating the shift from traditional in-person learning to independent or online learning through various digital platforms. The integrity of e-learning can be ensured by leveraging e-learning behavioral data. The objective of this research is to develop a novel data model to navigate the educational challenges of the COVID-19 era. Previous studies employed the Support Vector Machine (SVM) technique to predict student performance in an e-learning setting, yet they failed to contrast different SVM kernels and their outcomes. In contrast, this study uses SVM and compares three types of kernels: Radial, Polynomial, and Linear. The dataset used for this research was procured from X-API-Edu-Data. The SVM technique was utilized in a unique way to process the data, which comprised 17 variables and 40 observations. Notably, all 17 variables were character variables, with only four being numeric. Two variables, Raisedhands and Discussion, were selected for analysis due to their key role in effective learning and their association with student performance in an e-learning environment. The evaluation of the model was performed using the Topic variable, which represents the subjects in the dataset. The research findings revealed a marked improvement in accuracy compared to earlier studies. Among the three SVM kernels tested - Radial, Polynomial, and Linear, the Polynomial kernel demonstrated superior accuracy with a score of 0.9979. Therefore, the Polynomial model was deemed most appropriate for analyzing the Topic variable. In conclusion, the study indicates that the application of the e-learning method, specifically during the COVID-19 pandemic, proved highly effective in forecasting student performance.

In contemporary society, the widespread adoption of information and communication technologies has become integral to meeting daily needs. E-Government leverages these technologies to deliver efficient and secure services to citizens, particularly at the local government level. However, existing literature lacks comprehensive exploration into citizen preferences for utilizing e-government services, especially those offered by local governments. Addressing this gap, this study investigates citizen intentions to use e-government, focusing on the application system provided by local governments. Our research framework integrates three established models (UTAUT, TAM, and TPB) and employs empirical validation through a structured questionnaire. Data collection involved 97 respondents from diverse cities/regencies. Rigorous reliability and validity assessments were conducted on the questionnaire, with analysis performed using structural equation modeling (SEM). The findings underscore the significant influence of citizens' attitudes toward e-government, shaped by factors such as effort expectancy, facilitating conditions, and perceived risk. Furthermore, a positive and significant relationship between attitude and Intention to use revealed. This research contributes to a deeper understanding of citizen behavior towards e-government services, offering insights crucial for enhancing service delivery and citizen engagement at the local level.
