Abstract

Healthcare systems face growing challenges in protecting patient information, with more than 276 million healthcare records breached in 2024 alone. This study presents a proof-of-concept consortium blockchain framework that integrates Near Field Communication (NFC) based authentication with smart contract driven consensus to securely verify and synchronize Electronic Medical Records (EMRs) across multiple healthcare facilities. The system was tested in a simulated network of three Virtual Private Servers, achieving an average NFC verification time of 2.9 seconds and a consensus propagation time of 0.4 seconds, demonstrating stable performance suitable for near-real-time operations.Although these results are promising, the evaluation was limited to synthetic datasets, small-scale network conditions,and basic database security configurations. Future work will focus on scaling the system to larger and more diverse networks, strengthening cybersecurity measures, and ensuring full compliance with HIPAA and GDPR standards. By supporting the United Nations’3rd Sustainable Development Goal on Health and the 9th Sustainable Development Goal on Infrastructure and Innovation, this research contributes to the development of secure, interoperable, and sustainable healthcare information systems.

Abstract

The tsunami is a disaster that often occurs in Indonesia, there are no valid indicators to assess and monitor coastal areas based on functional land use and based on land cover which refers to the biophysical characteristics of the earth's surface. One of the recommended methods is the vegetation index. Vegetation index is a method from LULC that can be used to provide information on how severe the impact of the tsunami was on the area.In this study, an increase in the vegetation index was carried out using machine learning. The purpose of this study was to develop a tsunami vulnerability assessment model using the Vegetation Index extracted from Landsat 8 satellite imagery optimized with KNN, Random Forest and SVM. The stages of study, are: 1)extraction Landsat 8 images using algorithms NDVI, NDBI, NDWI, MSAVI, and MNDWI; 2) prediction of vegetation indices using KNN, Random Forest, and SVM algorithms. 3) accuracy testing using the MSE, RMSE, and MAE,4) spatial prediction using the Kriging function and 5) tsunami modelling vulnerability indicators. The results of this study indicate that the NDVI interpolation value is 0 - 0.1 which is defined as vegetation density, biomass growth, and moderate to low vegetation health. the NDWI value is 0.02 - 0.08 and the MNDWI value is 0.02 - 0.09 which is interpreted as the presence of surface water along the coast. MSAVI is a value of 0.1 – 0 which is defined as the absence of vegetation. The NDBI interpolation value is -0.05 - (-0.08) which is interpreted as the existence of built-up land with social and economic activities. From the results of research on the 10 areas studied, there are 3 areas with conditions that have a high level of tsunami vulnerability. 2 areas with medium vulnerability and 5 areas with low vulnerability to tsunami.

Abstract

Digital agriculture faces challenges, namely in integrating Elderly People (SENIORS) in digital transformation. The purpose of the study is to analyze and design UI/UX models according to user needs, expectations, and challenges. The method used is the Design Thinking approach which begins with literature study, then interviews are conducted to identify problems faced by users, and analyze the need to determine problem priorities. UI/UX prototypes are carried out to design solutions that suit user needs, and evaluations are carried out to collect user feedback. The data is assessed through the System Usability Scale (SUS) approach to appraise the designed user interface (UI). The evaluation results showed a "good" rating based on the SUS category, with a final average score of 74,391, so that the solutions designed meet usability standards for SENIORS users in the context of digital agriculture. Thus, the research carried out contributes to increasing the effectiveness and adoption of SENIORS in digital agriculture, as well as by designing user-friendly UI/UX models, making an important step towards inclusive and sustainable digital agriculture.

Abstract

Teknologi informasi menjadi salah satu bagian penting dalam perusahaan yang memberikan manfaat untuk meningkatkan efisiensi dan efektifitas proses bisnis, terutama di sektor pendidikan. Tujuan penelitian ini adalah menghasilkan rekomendasi mengenai kesiapan tata kelola teknologi informasi tepat gunadan investasi yang layak diimplementasikan pada Perguruan Tinggi XYZ. Permasalahan yang muncul disebabkan karena belum ada proses pemeriksaan mengenai kesesuaian standart sistem dan kesulitan dalam menghitung costbenefit yang diperoleh dari investasi sistem informasi. Penelitian ini menggunakan framework COBIT 5.0 domain DSS01, bertujuan memberikanrekomendasi tata kelola teknologi informasi pada bagian manage operation dan metode Information Economics untuk melakukan analisis manfaat investasi. Pengumpulan data dilakukan wawancara denganHead IT Operation dan beberapa staff. Hasil penelitian menggunakan COBIT5.0 domain DSS01, menunjukkan bahwa prosesmonitoring operasional yang diimplementasikan belum sepenuhnya dijalankan, yaitu sebesar 81%. Hasil analisis metode Information Economic, dampak ekonomis Enchanced ROImenyatakan bahwa nilai persentase simpleReturn on Investment sebesar 145,66% atau dengan skor 1, menunjukkan bahwa investasi ini memberikan keuntungan bagi perusahaan walaupun tidak besar.Kata Kunci: SistemInformasi, Tata Kelola, COBIT 5.0, Information Economics.

Abstract

Pandemi COVID-19 telah mengubah cara gereja menyampaikan pelayanan ibadah kepada jemaatnya. Salah satu upaya adaptasi yang dilakukan oleh GKI Tegalrejo Salatiga adalah menyediakan layanan streaming ibadah agar jemaat tetap dapat mengikuti ibadah secara daring. Namun, kualitas teknis penyiaran menjadi tantangan utama, sehingga diperlukan pelatihan penggunaan perangkat lunak Open Broadcaster Software (OBS) untuk meningkatkan mutu layanan streaming. Artikel ini melaporkan hasil kegiatan pengabdian masyarakat yang berfokus pada pelatihan OBS untuk tim multimedia gereja. Pelatihan ini mencakup pengenalan fitur OBS, teknik pengaturan kamera, audio, dan tata letak visual yang mendukung siaran yang lebih berkualitas. Hasil dari pelatihan menunjukkan peningkatan signifikan dalam kualitas streaming ibadah, baik dari segi tampilan visual, kestabilan siaran, maupun pengelolaan sumber daya teknis oleh tim multimedia.
