Abstract

Perkembangan teknologi digital, terutama dalam penggunaan smartphone, memberikan dampak signifikan pada gaya hidup manusia. Aplikasi mobile, khususnya dalam industri pariwisata, menjadi krusial dalam membantu wisatawan merencanakan perjalanan dengan efisien. Labuan Bajo, sebagai destinasi wisata terkenal di Indonesia, meluncurkan Aplikasi Wisata Labuan Bajo pada 25 November 2022, bertujuan memberikan informasi penting bagi wisatawan dan mendukung masyarakat lokal. eskipun telah diluncurkan, belum ada penelitian khusus menggunakan usability testing, seperti metode retrospective think aloud, untuk mengukur tingkat kebergunaan aplikasi tersebut. Oleh karena itu penelitian ini bertujuan untuk mengukur efektivitas, efisiensi, dan kepuasan pengguna terhadap Aplikasi Wisata Labuan Bajo. Melibatkan sepuluh responden dari berbagai latar belakang, termasuk sembilan wisatawan mancanegara dan satu wisatawan domestik, dalam rentang usia 20-59 tahun. Dengan memberikan tugas terkait fitur aplikasi, penelitian menganalisis tingkat keberhasilan, waktu penyelesaian, dan skor kepuasan pengguna. Hasil menunjukkan tingkat penyelesaian tugas mencapai 96%, menandakan efektivitas aplikasi yang baik. Meskipun demikian, efisiensi berdasarkan metode time-based efficiency hanya mencapai 13,1%, menunjukkan potensi peningkatan efisiensi. Skor kepuasan pengguna (SUS) sebesar 84,25 mengindikasikan kepuasan umum pengguna terhadap aplikasi, meskipun beberapa aspek seperti konsistensi fungsi dan kompleksitas perlu ditingkatkan. Aplikasi Wisata Labuan Bajo efektif dalam penyelesaian tugas, tetapi memerlukan perbaikan dalam efisiensi dan desain guna meningkatkan pengalaman pengguna secara keseluruhan

Abstract

This research was conducted to measure the usability of a system using two methods, RTA (Retrospective Think Aloud) and SUS (System Usability Scale). An object used in this research was shazam. The subject were 5 people, who are smartphone users in the age range of 10 to 50 years old. Finally, in this research RTA method showed that the shazam application is effective with a completion rate of 94.3% and efficient with a time-based efficiency of 0.108 task/second. While SUS showed that Shazam is still categorized as a class B application.

Abstract

This study aims to predict house prices in the United States based on features such as Avg. Area Income, Avg. Area House Age, Avg. Number of Rooms, and Area Population. The dataset used consists of several thousand entries without missing values. Through initial data exploration, a significant correlation was found between several features and house prices. Outliers were analyzed and considered in the modeling process. The Support Vector Machine (SVM) algorithm with various kernels was applied, where the Radial Basis Function (RBF) kernel showed the best performance, explaining about 70.78% of the variation in house prices. The results of this study highlight the potential of the SVM algorithm in property price prediction and provide insights for further property analysis.

Abstract

This study investigates academic performance variations across study programs at Politeknik eLBajo Commodus, blending quantitative analysis with qualitative insights to provide a holistic view of student achievement. Employing an Analysis of Variance (ANOVA) on 'Tes Bakat Skolastik' scores, we sought to identify significant differences in academic performance among the programs. Additionally, casual interviews with students were conducted to explore their perceptions of program selection, academic preparedness, and the challenges encountered. Our methodology combined statistical rigor with a nuanced understanding of student experiences, offering a comprehensive analysis of the factors influencing academic success. The quantitative phase involved comparing mean scores across programs using ANOVA, while the qualitative phase entailed gathering subjective insights from students regarding their academic journey and preparation. The results revealed no statistically significant differences in performance across study programs, indicating a baseline uniformity in academic achievement. However, student interviews highlighted a significant gap in pre-admission knowledge about program expectations and personal academic readiness. These findings suggest the need for enhanced pre-enrollment assessments and orientation programs to better align student expectations with academic demands. In conclusion, this study underscores the importance of a holistic educational approach that encompasses both statistical analyses and the lived experiences of students, advocating for initiatives that support informed decision-making and academic preparedness at the tertiary level.

Abstract

Blockchain technology has gained significant attention in recent years due to its potential to transform a wide range of industries. This review aims to comprehensively analyze blockchain technology's technical characteristics, applications, challenges, and limitations as addressed in academic literature published between 2014 and 2021. A total of 50 articles were included in the review after being evaluated for relevance, quality, originality, clarity, and practical or theoretical implications. The results of the review indicate that research on blockchain has progressed significantly in the past decade, with a wide range of studies exploring its technical characteristics, potential applications, and challenges and limitations. Technical characteristics of blockchain include its decentralized nature, the use of cryptographic techniques, and its potential to improve efficiency and reduce the need for intermediaries. Potential applications of blockchain include finance, supply chain management, and healthcare. Challenges and limitations of blockchain include scalability, energy consumption, regulatory issues, and risks and uncertainties. The results suggest that while blockchain technology has the potential to transform industries, there is still much work to be done to address its challenges and ensure its responsible deployment.

Abstract

Studi ini bertujuan untuk mengevaluasi prestasi akademik mahasiswa di Politeknik eLBajo Commodus dengan menggunakan metode standarisasi Z-Score. Analisis awal dari data IPK menunjukkan variasi yang signifikan antara program studi, yang menimbulkan kebutuhan akan metode evaluasi yang lebih adil. Metode standarisasi Z-Score diaplikasikan untuk mengidentifikasi 10 mahasiswa terbaik dari berbagai program studi. Hasil standarisasi memperlihatkan daftar mahasiswa yang lebih beragam dalam representasi program studi dibandingkan daftar berdasarkan IPK mentah. Studi ini merekomendasikan penerapan metode Z-Score sebagai kriteria evaluasi prestasi akademik untuk tujuan seperti seleksi beasiswa, penghargaan akademik, dan analisis internal guna meningkatkan kualitas pendidikan.
