Abstract

Introduction: Electrolyte imbalance frequently occurs in patients with chronic kidney disease (CKD) due to impaired renal regulation of ions such as sodium, potassium, chloride, and bicarbonate. Uncorrected abnormalities can lead to cardiac arrhythmias, neuromuscular dysfunction, and increased mortality. Regular monitoring is critical; however, conventional laboratory methods often require complex equipment and are inaccessible in low-resource settings. Electrochemical sensors provide a practical alternative by enabling rapid, direct measurement of electrolytes through electrical signals generated by ion-selective electrodes. Methods: This study presents the development and validation of a drop-casting-based electrochemical sensor designed for detecting sodium (Na+), potassium (K+, chloride (Cl-), and bicarbonate (HCO₃-) ions. The sensor was fabricated using a low-cost and straightforward method and tested with synthetic serum simulating both normal and renal failure conditions. Results: Calibration curves demonstrated strong linearity (R² > 0.93) for all ions, with minimal deviation for Na+ and K+ Performance validation showed acceptable sensitivity and stabilization time (<10 seconds), supporting its potential for point-of-care use. Conclusions: The device is easy to use, portable, and affordable, making it suitable for vocational healthcare workers in primary health centers and home-based care. Despite limitations in bicarbonate detection, the sensor shows promise for early electrolyte screening in decentralized healthcare settings. Further refinement and broader validation are recommended.

Abstract

The COVID-19 pandemic has had a profound impact on the tourism industry since its emergence in late 2019. Visitor restrictions have led to a significant decline in activity across various sub-sectors of tourism, and prospective travelers have experienced burnout due to isolation. In such a situation, the digital industry has emerged as a rapid and interim solution. One intriguing digital technology that has garnered attention is Virtual Reality (VR). These efforts have been undertaken to ensure the sustainability of tourism destinations, and VR technology has piqued the interest of potential tourists. Despite its effective role in virtual promotion and learning, particularly for cultural heritage and archaeological sites like the Trowulan Site, stakeholders need to be supported through education on immersive technologies such as VR and their utilization in tourism and education, especially in the field of history. The adoption of VR technology in tourism destinations has experienced significant growth, but issues have arisen due to the lack of Human Resources (HR) related to VR Tourism content creation. As a result, the presentation of VR Tourism experiences has been delayed in terms of content updates, which can have a detrimental impact on the image of the tourism destination, potentially undermining its full potential. Awareness of this issue has been recognized by the Tourism Awareness Group (Pokdarwis) Ladewa, a stakeholder involved in the management of tourism destinations and travel packages in the Trowulan region. To address this issue, a proposed solution involves training related to VR Tourism and Social Media Content Creation as part of the digital marketing strategy for the tourism destination. This training will primarily focus on tourism themes with a sub-theme of enhancing the capacity of the Tourism Awareness Group (POKDARWIS) LADEWA.

Abstract

Teknologi virtual tour mencapai puncak saat terjadi pandemi covid-19 dan menjadi solusi untuk tetap berwisata meskipun secara virtual saat ada pembatasan aktifitas. Virtual tour juga menjadi solusi untuk tetap menjaga objek wisata cagar budaya (heritage tourism) dari kerusakan sehingga bisa dikelola secara berkelanjutan. Pemasaran digital menjadi metode yang penting untuk diterapkan dalam pembuatan virtual tour. Sehingga pelaku industri pariwisata seperti pokdarwis bisa memaksimalkan metode ini. Sehingga perlu diadakan pengabdian kepada masyarakat terkait pembuatan virtual tour dan pemasaran digital untuk penguatan pariwisata berkelanjutan. Sasaran kegiatan pengabdian masyarakat ini adalah Pokdarwis Ladewa di Desa Trowulan, Kecamatan Trowulan, Kabupaten Mojokerto. Tujuan dari kegiatan pengabdian masyarakat ini adalah untuk meningkatkan kemampuan pemuda yang tergabung dalam organisasi pokdarwis dalam memasarkan situs cagar budaya di Desa Trowulan melalui pembuatan virtual tour 3600 berbasis eco-heritage.

Abstract

Purpose: This research investigates the effectiveness of YOLO (You Only Look Once) and Convolutional Neural Network (CNN) in real-time face mask recognition, addressing the challenges posed by mask-wearing in infectious disease prevention.Method: Utilizing a diverse dataset and employing YOLO's object detection and a combined Haar Cascade Algorithm with CNN, the study evaluated key performance indicators, including accuracy, framerate, and F1 Score.Results: Results indicated that CNN outperformed YOLO in accuracy (99.3% vs. 79.3%) but operated at a slightly lower framerate. YOLO excelled in recall and precision, presenting a compelling choice for specific application needs. The research underscores the importance of considering factors beyond accuracy for informed decision-making in the realm of face mask recognition.Novelty: This research evaluates the real-time performance of YOLO and CNN algorithms in masked face recognition, highlighting the crucial balance between framerate efficiency and detection accuracy.
