Abstract

The development of educational technology encourages the application of digital learning systems to support learning activities to take place more optimally and save time. Universitas Bhinneka PGRI has implemented the Learning Management System (LMS) as a means of supporting the digital learning system. A study of the level of user acceptance needs to be carried out to identify various influential factors so that they can be used for development according to developments based on the UTAUT method. This study aims to analyze the factors that affect LMS acceptance in users at Bhinneka PGRI Tulungagung University using the UTAUT method. This study uses a quantitative approach with a survey research type involving 95 users as a sample selected by purposive sampling technique. Data were collected through questionnaires with a likert scale of 1-5 and analyzed using the SEM-PLS method which included outer model test, inner model, and hypothesis test. This research resulted in LMS acceptance at UBHI which was quite good. This is shown by Performance Expectancy having a positive and significant influence on Behavioral Intention of 0.235. Effort Expectancy was 0.298, and Social Influence was 0.445. In addition, Behavioral Intention had a positive and significant effect on Use Behavior with a value of 0.673. Meanwhile, Facilitating Conditions had a positive but insignificant effect on Use Behavior with a coefficient value of 0.134. This study concludes that the use of LMS is influenced by the perception of benefits, ease of use, and social environmental support, compared to supporting facilities. This research contributes theoretically to the development of the UTAUT model and practically as an evaluation of improving the quality of LMS in universities.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh kebiasaan pengguna terhadap efektivitas desain antarmuka website akademik menggunakan metode Heatmap Microsoft Clarity. Penelitian sebelumnya umumnya masih berfokus pada pendekatan berbasis persepsi pengguna melalui kuesioner, sehingga belum sepenuhnya mampu merepresentasikan perilaku pengguna secara aktual dalam berinteraksi dengan website akademik. Obyek penelitian adalah website Program Studi Informatika Universitas Bhinneka PGRI (https://infubhi.my.id), dengan melibatkan 125 responden yang terdiri dari mahasiswa, dosen, dan tenaga kependidikan. Metode pengumpulan data dilakukan melalui observasi perilaku pengguna berbasis heatmap, penyebaran kuesioner dengan skala Likert 1–5, serta validasi hasil menggunakan wawancara mendalam. Penggunaan heatmap dalam penelitian ini berperan sebagai sumber data empiris non-persepsional yang merekam pola interaksi pengguna secara nyata, seperti klik dan aktivitas penelusuran halaman. Analisis data dilakukan dengan pendekatan Partial Least Squares (PLS) untuk menguji hubungan antarvariabel yang meliputi kebiasaan pengguna, desain antarmuka, dan efektivitas website. Hasil penelitian menunjukkan bahwa kebiasaan pengguna berpengaruh signifikan terhadap desain antarmuka, dan desain antarmuka berpengaruh signifikan terhadap efektivitas website, sedangkan kebiasaan pengguna tidak berpengaruh langsung terhadap efektivitas website. Dalam model penelitian ini, desain antarmuka diposisikan sebagai variabel mediasi yang menjembatani hubungan antara kebiasaan pengguna dan efektivitas website akademik. Temuan ini mengindikasikan bahwa peningkatan efektivitas website akademik lebih bergantung pada perbaikan desain antarmuka berbasis pola perilaku pengguna daripada sekadar intensitas penggunaan. Penelitian ini memberikan implikasi praktis bagi pengembang sistem informasi akademik untuk mengoptimalkan desain antarmuka berdasarkan data interaksi nyata pengguna.

Abstract

The advent of digital technology over the past decade has transformed the way higher education institutions deliver services to their academic communities. Digital transformation has positioned academic websites as the primary communication channel between students and higher education institutions, yet interface evaluation continues to rely on perception-based methods that fail to capture actual user behavior. This study analyzes interaction patterns of users on a simulative academic information website, identifies interface elements that create friction, and proposes evidence-based design improvements. A quantitative descriptive approach was adopted using Microsoft Clarity as the data collection instrument, which automatically recorded click heatmap, scroll heatmap, movement heatmap, and session replay data. Thirty interaction sessions from 21 unique users were gathered through purposive sampling of active students at Bhinneka PGRI University Tulungagung. The findings reveal that click intensity was concentrated on the homepage and the "Kampus" menu, while average scroll depth reached only 57.11%, session duration averaged 1.1 minutes, and the quick-back rate stood at 36.67%. Additionally, a dead-click rate of 6.67% was observed, reflecting user confusion toward visually interactive but non-responsive elements. Taken together, these results demonstrate that the Microsoft Clarity heatmap method is capable of surfacing usability problems that conventional perception-based evaluation approaches consistently overlook.

Abstract

Public services at the village level are the spearhead of government services closest to the community. However, most villages in Indonesia still rely on manual systems for administrative management, including the process of submitting certificates, recording citizen data, and delivering information. Administrative services in Wonorejo Village, Sumbergempol District, are still carried out manually, causing various obstacles, such as inefficiency, long queues, service delays, and limited access to information for residents. This study aims to design and build a website-based village service system integrated with a chatbot to improve the effectiveness and efficiency of administrative services. The system was developed using the Extreme Programming (XP) method through two development iterations, utilizing the PHP-based Laravel framework, MySQL as the database, and Dialogflow as the Natural Language Processing (NLP) platform for the chatbot. The system's main features include online letter submission, application status monitoring, village information management, and an interactive chatbot. Functional testing was conducted using the black box testing method, while user acceptance was measured through a User Acceptance Test (UAT) using an ISO 25010-based instrument involving 12 respondents. The UAT results showed a satisfaction percentage of 95%, included in the very good category. The developed system has proven capable of supporting the digital transformation of public services at the village level.
