Abstract

Penelitian ini bertujuan merancang user experience (UX) aplikasi layanan darurat bagi pengendara sepeda motor menggunakan metode Design Thinking. Metode ini terdiri dari lima tahapan: empathize, define, ideate, prototype, dan testing. Tahap empathize melibatkan wawancara dengan pengendara kendaraan bermotor untuk memahami masalah utama mereka. Tahap define menghasilkan persona pengguna dan empathy map untuk memperjelas kebutuhan dan masalah pengguna. Pada tahap ideate, berbagai ide dikembangkan untuk pembuatan prototipe UX aplikasi. Prototipe diuji untuk mendapatkan umpan balik dari pengguna. Hasil penelitian menunjukkan bahwa pendekatan Design Thinking efektif dalam merancang UX aplikasi yang memenuhi kebutuhan pengendara sepeda motor, menyediakan layanan darurat seperti tambal ban, pom bensin, bengkel, towing, derek, dan konsultasi kesehatan. Pengujian menggunakan SEQ (Single Ease Question) menunjukkan bahwa aplikasi ini mudah digunakan oleh pengguna

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

Land cover will change due to population pressure, resource use, and human interest in space. Measuring the land area is important to determine how much-converted land is positive and negative. The vegetation on land was determined by how densely the plants were spread out. This study is conducted in Palabuhanratu, Sukabumi Regency. Aims to test and compare how accurate EVI and SAVI are at seeing vegetation density. The images used are from Landsat 8 in 2018 and 2022. Calibration is performed using high-resolution images, followed by field surveys with 98 points from polygon sampling. The average accuracy of the results from EVI is 49%, while the average accuracy of the results from SAVI is 45%. So, we can say that the EVI or SAVI based-input gives a similar result on observing the vegetation density in Palabuhanratu.

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

Landslides are a significant geomorphological hazard in Indonesia that can damage infrastructure and disrupt social activities. In Majalengka Regency, variations in topographic conditions result in different levels of landslide susceptibility, which may affect public facilities, including educational institutions. This study aims to analyze the spatial distribution of landslide susceptibility and evaluate the exposure of educational facilities using a GIS-based Weighted Overlay method with seven parameters. The results indicate that High and Very High susceptibility areas cover approximately 33,284 hectares and 17,388 hectares, respectively, and are mainly concentrated in the southern part of Majalengka Regency. Of the 672 educational facilities, 162 schools (24.1%) are located within landslide-prone zones, including 47 schools in Very High susceptibility areas. These findings highlight the influence of terrain conditions, rainfall, soil characteristics, and proximity to infrastructure in shaping landslide susceptibility. This study provides a spatially explicit evaluation of educational facility exposure, offering empirical baseline data to support local disaster mitigation strategies and school safety planning.

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.
