Abstract

As software applications become increasingly complex, there is a growing need for scalable, flexible, and high-performance backend solutions. Cloud computing-based application programming interfaces (APIs) address these demands by enabling developers to offload resource-intensive tasks to the cloud while eliminating the burden of infrastructure management. This study presents a case study using Obesifix, a mobile health application for real time dietary monitoring and personalized nutrition recommendations. Two deployment models were evaluated: a traditional server-based architecture using Google Compute Engine (GCE) and a serverless approach using Google Cloud Run (GCR). Performance testing was conducted with Apache JMeter under simulated loads of 60, 120, and 180 users across four critical API endpoints (register, login, recommendation, prediction). Results show that GCR consistently achieved 20–30% lower response times and 15–20% higher throughput compared to GCE, while maintaining 0% error rate, lower memory consumption, and more balanced virtual central processing unit (vCPU) utilization. Time to first byte (TTFB) remained below 800 ms across all scenarios, confirming good server responsiveness. These findings highlight the scalability and efficiency benefits of serverless architectures for mobile health applications. Future research should explore asynchronous programming paradigms, autoscaling thresholds, and cost-performance trade-offs, as well as multi-cloud deployments to enhance system resilience and generalizability.

Abstract

Keterlibatan verbal anak usia dini pada kegiatan pembelajaran di KB-TK Cita Mandiri masih terbatas karena minimnya media interaktif berbasis teknologi yang mendorong partisipasi aktif anak. Pengabdian kepada Masyarakat (PKM) ini bertujuan mengimplementasikan media pembelajaran digital berbasis interaksi suara dalam kegiatan pembelajaran di KB-TK Cita Mandiri, Surabaya. Sasaran kegiatan adalah anak usia 2–5 tahun (n=10) dan guru pendamping (n=5). Metode pelaksanaan mencakup sosialisasi program, penerapan media, pendampingan dan evaluasi, serta observasi perilaku anak pada dua titik waktu (T1 dan T2) dan evaluasi penerimaan-usabilitas media oleh guru menggunakan instrumen Technology Acceptance Model (TAM) dan System Usability Scale (SUS) yang dilaksanakan pada hari terpisah dari sesi implementasi. Hasil observasi menunjukkan tingkat keterlibatan anak yang tinggi sejak awal sesi dan relatif terjaga hingga akhir sesi (rata-rata skor T1=4,58 menjadi T2=4,67 dari skala 1–5). Guru menunjukkan penerimaan yang positif terhadap media (rata-rata skor TAM=4,98 dari skala 1–5) dengan tingkat usabilitas tergolong sangat baik (rata-rata skor SUS=91,5). Kegiatan ini menunjukkan bahwa media pembelajaran digital berbasis interaksi suara dapat diterima dengan baik dan mendukung keterlibatan belajar anak di lingkungan PAUD.
