Abstract

This study examines the influence of e-wallet implementation, digital security perceptions, and technology reliability on digital payment system usage decisions in East Java. Using a quantitative research approach, data were collected from 150 active digital payment users through a structured questionnaire measured on a five-point Likert scale. The data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) version 3 to evaluate both the measurement and structural models. The results indicate that e-wallet implementation has a positive and significant effect on digital payment usage decisions, highlighting the importance of usability, system integration, and functional design. Digital security perceptions emerge as the strongest determinant, emphasizing that users’ confidence in data protection and transaction safety plays a critical role in shaping adoption behavior. Technology reliability also shows a significant positive influence, demonstrating that system stability and transaction accuracy are essential for sustaining user trust and continued usage. Overall, the findings suggest that digital payment adoption in East Java is driven by a combination of effective system implementation, strong security perceptions, and reliable technological performance. This study contributes to the digital finance and fintech adoption literature by providing empirical evidence from a regional context and offers practical insights for e-wallet providers and policymakers to strengthen digital payment ecosystems.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) in Indonesia continue to face inefficiencies in inventory management due to manual stock recording, data inconsistency, and delays in operational decision-making. In Serang City, these challenges often lead to stockouts, excess inventory, and limited business scalability. This study aims to develop and evaluate a mobile-based automated inventory management system that supports real-time stock monitoring and decision-making for MSMEs. The research employs a Research and Development (R&D) approach integrated with the Agile-Scrum methodology, encompassing problem identification, user requirement analysis, system design, prototype development, functional testing, and usability evaluation. Functional validation was conducted using black box testing, while system usability was assessed using the System Usability Scale (SUS) involving 15 MSME users. The results indicate that all core system functions achieved a 100% success rate, including automated stock recording, cloud-based data synchronization, real-time notifications, and dashboard analytics. The usability evaluation produced an average SUS score of 82.5, classified as Excellent, indicating high user acceptance and ease of use. These findings demonstrate that the proposed system effectively improves inventory accuracy, operational efficiency, and decision-making quality, contributing to MSME digital transformation in developing regions.

Abstract

Kecamatan Cibeber, Kota Cilegon, merupakan wilayah permukiman yang berada dekat dengan aktivitas perkotaan dan industri sehingga membutuhkan sistem pemantauan kualitas air yang praktis, cepat, dan mudah digunakan oleh masyarakat. Kegiatan pengabdian kepada masyarakat ini bertujuan menerapkan alat monitoring kualitas air berbasis mikrokontroler untuk membantu kelompok masyarakat memantau parameter pH, kekeruhan, suhu, dan Total Dissolved Solids (TDS) secara real-time. Sistem dirancang menggunakan ESP32, sensor pH, sensor turbidity, sensor suhu DS18B20, sensor TDS, LCD 16x2, koneksi Wi-Fi, dan dashboard web. Metode pelaksanaan meliputi identifikasi kebutuhan, perancangan perangkat, perakitan dan pemrograman, kalibrasi sensor, instalasi pada titik uji, pelatihan pengguna, serta evaluasi pemakaian. Hasil kegiatan menunjukkan bahwa alat dapat membaca parameter air secara stabil, menampilkan data pada dashboard web, dan memudahkan peserta memahami perubahan kondisi air. Rata-rata hasil pengukuran pada tiga titik uji menunjukkan pH meningkat dari 6,4 menjadi 6,8, kekeruhan menurun dari 11,2 NTU menjadi 7,8 NTU, suhu relatif stabil dari 29,6°C menjadi 29,1°C, dan TDS menurun dari 285 ppm menjadi 240 ppm setelah pendampingan dan tindak lanjut kebersihan sumber air. Kegiatan ini menunjukkan bahwa teknologi mikrokontroler dapat menjadi teknologi tepat guna untuk mendukung pemantauan kualitas air berbasis komunitas.

Abstract

Digital transformation in the banking sector has brought convenience to financial transactions through mobile banking applications. However, the quality of User Experience (UX) and User Interface (UI) is still a challenge, especially for people with low digital literacy. This service activity aims to improve the understanding and skills of the community in Banten Province in using digital banking applications effectively and safely. The implementation method includes an initial survey, simulation-based training, focus group discussions (FGDs), pre-post test evaluations, and the formation of village digital communities. The participants consisted of MSME players, housewives, and students, with a total of 120 people. The results of the activity showed a significant improvement in the digital literacy aspect, where the participants' understanding score rose from 52.3% to 83.7%. As many as 88% of participants were able to complete digital transactions independently after the training. The focus on digital security also increased user trust in the app. FGD findings indicated the need for improvement in application design, particularly interface navigation, icon size, and language simplification. Community-based UX/UI recommendations have been compiled and submitted to partner banks. The outputs of the activity include scientific articles, service reports, and the formation of a digital community forum for banking application users. This activity proves that an educative and participatory approach is able to answer the challenges of banking digitalization in real terms. This program is expected to become a replication model in an effort to increase digital financial inclusion based on local needs.
