Abstract

Digital transformation in the public sector has encouraged the development of queuing systems that not only organize service flows but also provide faster and more accurate access to information for citizens. Gebang Putih Urban Village, a community partner of the Electronic Engineering Polytechnic Institute of Surabaya (PENS), implemented a digital queuing system based on Android and web platforms in 2024; however, the system still had limitations in terms of responsiveness and communication channels with citizens. This community service activity focuses on the technical optimization of the queuing system by integrating a chat-based interaction feature into the mobile application and simplifying the queue number retrieval flow through conversational interaction. The system was developed using a User-centered design (UCD) approach, with key stages including needs analysis based on the evaluation of the previous system, design of a new system architecture, implementation of chat integration, and internal testing with urban village officers as key users. The optimization results cover three main technical aspects: (1) integration of the chat service module into the mobile application without modifying the core queuing logic, (2) a queue number retrieval feature via chat that is directly connected to the digital queuing module, and (3) a two-way chat channel between citizens and officers facilitated through a web-based dashboard. Internal trials indicate improvements in service workflows, reduced face-to-face interactions for simple inquiries, and increased staff understanding of how to use the digital system. From a community engagement perspective, this work represents a development and capacity-building phase that strengthens officers’ ability to manage technology-based services and provides a technical foundation that is ready to be disseminated and replicated in other urban villages with minimal adaptation.

Abstract

This study proposes a sector-based, midpoint-driven enhancement of the low-energy adaptive clustering hierarchy (LEACH) protocol to address energy imbalance and inconsistent cluster head (CH) placement in wireless sensor networks (WSNs). Conventional LEACH and its variants often rely on random CH selection and produce uneven cluster geometries, accelerating node depletion and shortening network lifetime. The proposed method divides the network into four sectors and applies a midpoint-guided CH selection mechanism that prioritizes nodes near the geometric center of each sector, thereby shortening intra-cluster communication distances and balancing energy consumption. The protocol is evaluated through Python-based simulation using 100 randomly deployed nodes in a 200×200 m² monitoring area and is compared with several widely used LEACH-based protocols under identical radio and traffic parameters. Key performance metrics include first node death (FND), half nodes death (HND), all nodes death (AND), residual energy, and throughput. Simulation results show lifetime gains of roughly 30–40 % across standard lifetime metrics relative to the original LEACH, while maintaining higher residual energy and stable throughput. These findings highlight the suitability of the protocol for long-duration IoT and smart monitoring applications where energy efficiency is critical.

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.
