Abstract

This paper proposes an innovative method to enhance Human-Computer Interaction (HCI) for Linux Command Line Interface (CLI) applications by integrating Telegram bot piping. Despite the power of CLI, its complexity often deters users, particularly those less experienced with technology. We introduce a solution leveraging Telegram bots to provide a more intuitive and accessible interface for interacting with CLI tools. Users can issue commands via Telegram, receiving real-time feedback and executing tasks without extensive CLI knowledge. Our study includes design, implementation, and evaluation phases, demonstrating high user satisfaction with the Telegram bot integrated CLI applications. The approach significantly improves usability, reduces the learning curve, and broadens the accessibility of Linux systems. The user feedback indicated high satisfaction with the Telegram bot integrated CLI applications, with users finding it effective, user-friendly, and preferable over traditional CLI interfaces, with a user satisfaction score of 95.3%

Abstract

Mobile devices are vulnerable to shoulder surfing and smudge attacks, which should occur when a user enters a PIN for authentication purposes. This attack can be avoided by implementing a rotary entry pad mechanism. Despite this, several studies have found that using a rotary entry pad reduces user usability. This study uses a Design Research Methodology approach. It will implement a rotary entry pad authentication in the Android operating system as an authentication method to protect the device against Shoulder Surfing Attacks and Smudge Attacks. Furthermore, it combined JSON Web Token (JWT) to secure the authentication process from the client to the server. At the end of implementation, it compared with other studies in terms of usability and evaluated it using the TQ-Model, which showed that the usability aspect has improved. Regarding security, we conducted a shoulder surfing attack simulation to assess the efficacy of guessing PINs. The results showed that only a limited number of attempts were successful, with two out of five samples failing to guess any numbers and only one sample successfully guessing six 10-digit PIN combinations out of 10 to the power of 10. The security test results show that shoulder surfing attacks are more difficult to perform after implementing the rotary entry pad. The evaluation showed that the JSpinpad performed better, with seven parameters showing improvement, one parameter showing a decline, and ten parameters remaining unchanged.

Abstract

The transformation of global education towards e-learning poses challenges to students' motivation and self-efficacy, impacting inequalities in academic achievement. A number of studies indicate that the relationship between motivation, self-confidence, and achievement remains complex and warrants further investigation. This study conducted a meta-analysis to assess the strength of the relationship between motivation, self-efficacy, and academic achievement in the context of digital learning. By analyzing 52  recent studies (2004–2025), we used a randomized effects model to account for heterogeneity between studies. The correlation coefficient reported in each study was converted to Fisher's Z to normalize the distribution of effects. Subsequently, the meta-analytic SEM was performed to test the self-efficacy mediation model. The results of the meta-analysis showed that the combined correlation between motivation and self-efficacy (r = 0.52) and motivation and academic achievement (r = 0.44) exhibited a moderate to strong ffect. The meta- structural equation modelling (SEM) analysis confirmed that self-efficacy mediates a partial influence of motivation on Academic Achievement (β indirect = 0.355, 36% of the total influence). Theoretically, these results strengthen social cognitive theory (Bandura) and self-determination theory (Deci & Ryan) in the field of e-learning. Practically, the results suggest that teachers and institutions should develop interventions that increase students' intrinsic motivation and self-confidence (e.g., through autonomy-supporting learning) and support educational policies that incorporate non-cognitive psychological indicators into the curriculum. This study provides a more accurate estimate of average effects and supports the development of the theory and practice of digital education based on cross-cultural evidence.

Abstract

Although cryptographic security is often the main concern in e-voting system development, practical implementation failures are frequently associated with poor user interfaces that increase cognitive load and voting errors. This study evaluates the effectiveness of User-Centered Design (UCD) interventions in improving usability and voter confidence in an e-voting system. A one-group pretest-posttest design was applied to 36 respondents representing novice voters. Usability was measured using the System Usability Scale (SUS) before and after the interface redesign. The intervention focused on visual hierarchy, navigation consistency, status visibility, and error prevention. The results show a statistically significant improvement, with the mean SUS score increasing from 69.10 in the marginal category to 95.76 in the excellent category. The paired sample t-test produced t(35) = -7.3441 with p < 0.0001, while Cohen's d reached 1.2130, indicating a large practical effect. The standard deviation also decreased from 21.98 to 3.09, demonstrating a more consistent user experience. These findings indicate that interface optimization is essential for strengthening accessibility, voting accuracy, and user trust in digital democracy systems.

Abstract

Kerangka kerja Yii 2 banyak digunakan untuk mengembangkan aplikasi web modern karena kemampuan performa tinggi dan arsitektur yang terstruktur. Namun, kerentanan nyata seperti CVE-2018-7269 menunjukkan bahwa masalah keamanan masih dapat terjadi meskipun terdapat mekanisme bawaan. Penelitian ini mengevaluasi ketahanan keamanan aplikasi unggah berkas berbasis Yii 2 dengan menggunakan kerangka pemodelan ancaman STRIDE dan model penilaian risiko DREAD. Empat vektor serangan—SQL Injection (SQLi), Cross-site Scripting (XSS), Remote Access Trojan (RAT) melalui unggahan berkas, dan Buffer Overflow—disimulasikan dalam lingkungan terkontrol dengan mengacu pada CVE dunia nyata. Hasil eksperimen menunjukkan bahwa aplikasi berhasil memblokir seluruh serangan melalui validasi bawaan, pembatasan masukan, dan pemfilteran ketat tipe MIME. Penilaian DREAD mengungkapkan tingkat risiko tinggi untuk SQLi (7.6) dan RAT (7.8), sedangkan XSS (5.6) dan Buffer Overflow (6.2) dikategorikan pada risiko sedang. Temuan ini menunjukkan bahwa aplikasi berbasis Yii 2 yang diuji memiliki mekanisme keamanan yang efektif dalam kondisi pengujian, sekaligus menekankan pentingnya pengujian berkelanjutan dan penerapan SSDLC.

Abstract

The "MASTER" academic information system currently exhibits critical limitations in user experience. Heuristic evaluation identified major issues in consistency, standards, and recognition rather than recall (severity 4), causing high cognitive load and disorientation due to a flat-list navigation structure. This research aims to redesign the interface using the User-Centered Design (UCD) approach based on ISO 9241-210. Design solutions were developed to address user needs for structured navigation, task-hierarchy menu grouping, and quick access to the Semester Learning Plan (RPS) module. These solutions applied principles of visual hierarchy and the separation of academic and administrative functions. A subsequent evaluation using the SUPR-Q instrument with 30 respondents showed significant improvements in Loyalty (+1.20), Appearance (+0.72), and Trust (+0.70), achieving a 96.67% user preference rate for the new design. Although there was a slight decrease in usability (-0.06) indicating a temporary user adaptation period, findings demonstrate that the UCD application effectively reduces cognitive load, increases navigation efficiency, and enhances the overall user experience quality.

Abstract

Perkembangan teknologi membawa kemajuan pesat dalam bidang Ilmu Pengetahuan dan Teknologi (IPTEK). Kemajuan ini memberikan akses ke dalam ketersediaan literatur dan kemudahan dalam mengakses informasi melalui berbagai media. Namun, keamanan atas informasi dan data diperlukan sebagai bentuk kerahasiaan, menjaga integritas data dan otentikasi. Oleh karena itu diperlukan ilmu kriptografi yang dapat menyandikan data. Salah satu contoh penggunaannya ialah dengan algoritma kriptografi. Algoritma DES merupakan algoritma kriptografi simetris yang dapat bekerja dengan cepat. Algoritma 3DES yang merupakan pengembangan dari DES memakai panjang kunci tiga kali ukuran kunci DES dan tiga kali perulangan skema DES. Sedangkan ElGamal yang merupakan algoritma kunci publik juga memiliki tingkat keamanan yang baik karena sulitnya menghitung logaritma diskrit. Tentunya ketiga algoritma memiliki performansi dan keunggulan yang berbeda. Terutama jika digunakan sebuah dokumen sebagai input dan output. Fokus penelitian membahas perbandingan kecepatan enkripsi dekripsi data dan alokasi memori algoritma DES, 3DES dan ElGamal pada data teks txt yang diimplementasikan dalam bahasa pemograman C.
