Abstract

Quality education relies on effective learning methods. However, some students struggle to grasp the concepts taught in basic physics courses, often due to the lack of innovative teaching approaches in physics education. Traditional teaching methods can lead to student disinterest and difficulty in understanding the material. To address these challenges, integrating engaging technology into education is essential. Augmented Reality (AR) technology, which blends virtual elements with the real world, has emerged as a popular learning tool. But can AR effectively enhance learning experiences at FKIP UNIPA? To explore this, research was conducted to develop AR teaching materials using the Design Science Research method and gauge student interest in AR. Hypothesis testing using the Hedonic Motivation System Adoption Model (HMSAM) revealed that students at FKIP UNIPA responded positively to the AR teaching materials. The results showed that factors like perceived usefulness, curiosity, and enjoyment significantly influence students' willingness to use AR by 53.5%. In summary, the findings suggest that AR technology holds promise in improving learning outcomes and student engagement in physics education.

Abstract

Penelitian ini bertujuan untuk menganalisis kepuasan pengguna terhadap aplikasi mobile Detik.com, salah satu portal berita terbesar di Indonesia, yang mengalami penurunan kunjungan sejak Maret 2020. Meskipun aplikasi ini menyediakan akses cepat dan efisien ke berbagai berita terkini, terdapat beberapa tantangan yang memengaruhi kepuasan pengguna, seperti gangguan iklan dan masalah teknis. Untuk memahami sentimen pengguna, penelitian ini menggunakan pendekatan analisis sentimen dan pemodelan topik dengan metode Latent Dirichlet Allocation (LDA). Data yang dianalisis diambil dari ulasan pengguna aplikasi Detik.com di Google Play Store yang dikumpulkan melalui teknik web scraping. Sebanyak 14.320 ulasan dianalisis, dengan periode pengumpulan data dari Agustus hingga September 2023. Proses prapemrosesan data melibatkan beberapa tahap, termasuk pembersihan, tokenisasi, dan penyaringan, untuk memastikan kualitas data yang digunakan dalam analisis. Sentimen pengguna dikategorikan sebagai positif, negatif, atau netral. Berdasarkan hasil analisis, mayoritas pengguna menyampaikan sentimen positif sebesar 45,06% terhadap aplikasi, terutama terkait kecepatan loading dan kualitas konten. Namun, sekitar 41,18% ulasan mencerminkan sentimen negatif, yang sebagian besar disebabkan oleh masalah teknis dan gangguan iklan. Pemodelan topik menggunakan LDA mengidentifikasi 15 topik utama yang dibahas dalam ulasan pengguna, dengan 6 topik mencerminkan keluhan, 4 topik berisi ulasan positif, dan 5 topik bersifat netral. Hasil analisis pemodelan topik menunjukkan bahwa meskipun aplikasi Detik.com memiliki rating yang baik, masih terdapat beberapa aspek yang perlu ditingkatkan untuk meningkatkan kepuasan pengguna. Masalah seperti gangguan iklan, kesulitan login, dan kualitas konten menjadi fokus utama keluhan pengguna. Penelitian ini memberikan wawasan bagi pengembang aplikasi Detik.com untuk lebih memahami kebutuhan dan ekspektasi pengguna. Dengan meningkatkan aspek teknis dan mengurangi gangguan iklan, aplikasi ini memiliki potensi untuk meningkatkan pengalaman pengguna dan mempertahankan posisinya sebagai salah satu portal berita terkemuka di Indonesia.

Abstract

This study developed and evaluated a mobile application for infrastructure rental at the Quality Assurance Agency for Education (BPMP) in West Papua using the Design Science Research (DSR) approach in the field of Information Systems (IS). This application, the first designed specifically for the needs of BPMP West Papua and integrated with the existing system, was assessed based on usability and user acceptance through interviews, black box testing, and effectiveness testing using Structural Equation Modeling (SEM) with the Technology Acceptance Model (TAM) approach. The black box testing results indicated successful application development. Evaluation with 64 respondents through hypothesis testing showed that social influence and technological anxiety significantly affect attitudes toward accepting the use of the application. This highlights the importance of considering these factors for the successful implementation of the mobile application at BPMP West Papua, potentially enhancing the efficiency of infrastructure rental.

Abstract

This study explores the adoption of ride-hailing services in West Papua, a developing region in Indonesia, where concerns about service performance and security risks influence user decisions. Guided by the Theory of Planned Behavior (TPB), the research examines how service performance, social influence, and perceived security risks affect users’ behavioral intention and actual usage. A total of 158 valid responses were collected through a quantitative survey, and data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). Findings reveal that service effectiveness and social influence significantly influence behavioral intention, while efficiency and certainty do not. Additionally, certainty, effectiveness, and behavioral intention strongly affect user behavior. The model demonstrates moderate explanatory power with R² values of 0.561 for behavioral intention and 0.600 for user behavior. These results suggest that enhancing perceived service effectiveness and leveraging social influence can encourage adoption in regions with limited digital infrastructure. The study contributes to understanding technology acceptance in underdeveloped areas and offers practical insights for ride-hailing providers aiming to improve user trust and engagement.

Abstract

E-marketplaces play a pivotal role in Indonesia’s digital economic transformation; however, infrastructural limitations, high logistical costs, and low levels of technological literacy hinder their adoption in West Papua Province. Jasa Titip (JASTIP) represents an informal digital facilitation mechanism that enables communities to collectively and affordably access e-marketplace products. Importance–Performance Map Analysis (IPMA) is used to identify strategic intervention priorities for e-marketplace adoption in West Papua using an expanded Unified Theory of Acceptance and Use of Technology (UTAUT) framework. The moderating influence of gender in community-based social support is examined. PLS-SEM was used to analyze data from 177 respondents. Results show that enabling environments, hedonic incentives, and social influence greatly affect behavioural intention and utilization. Gender also moderates social impact and behavioural intention, highlighting its function in adoption. The model explains 62.1% of behavioural intention and 66.2% of use behaviour. Policymakers and e-marketplace stakeholders should learn from these results about the necessity of inclusive initiatives that account for gender-specific adoption habits. Moreover, they highlight the critical role of JASTIP practices in overcoming structural barriers to digital access in underserved regions

Abstract

Teknologi Generative Artificial Intelligence (GenAI) berperan strategis dalam transformasi pendidikan tinggi, termasuk dalam personalisasi pembelajaran, otomatisasi konten, serta dukungan administratif dan penelitian. Salah satu aplikasi GenAI yang paling banyak diadopsi adalah ChatGPT, model bahasa alami berbasis AI dari OpenAI. Namun, tingkat adopsi berkelanjutan oleh mahasiswa, khususnya pada institusi pendidikan tinggi di wilayah berkembang seperti Universitas Papua di Papua Barat, masih rendah dan belum banyak dikaji. Studi ini bertujuan menganalisis pengaruh kualitas argumen, kredibilitas sumber, kesenangan yang dirasakan, persepsi kegunaan (perceived usefulness), dan kemudahan penggunaan (perceived ease of use) terhadap persepsi kegunaan informasi (information usefulness), serta implikasinya terhadap penggunaan ChatGPT dan kinerja belajar mahasiswa yang diukur melalui efektivitas, efisiensi, dan kepastian hasil belajar. Pendekatan kuantitatif digunakan dengan menyebar kuesioner daring kepada 140 mahasiswa aktif Universitas Papua yang telah menggunakan ChatGPT dalam konteks akademik. Analisis data dilakukan dengan metode Partial Least Squares Structural Equation Modeling (PLS-SEM), mengintegrasikan model Information Adoption Model (IAM), persepsi kegunaan (perceived usability),  dan dimensi kinerja pembelajaran. Hasil menunjukkan bahwa perceived usefulness dan perceived ease of use berpengaruh signifikan terhadap information usefulness, yang berdampak positif terhadap kepercayaan belajar, penggunaan ChatGPT, efektivitas, dan efisiensi pembelajaran. Namun, konstruk lain seperti argument quality, perceived enjoyment, dan source credibility tidak berpengaruh langsung signifikan terhadap information usefulness. Nilai koefisien determinasi (R²) menunjukkan daya prediksi moderat hingga kuat. Temuan menegaskan pentingnya perluasan model adopsi dengan mempertimbangkan faktor eksternal seperti literasi digital, kepercayaan terhadap AI, serta dukungan institusional untuk mendorong adopsi GenAI yang berkelanjutan.
