Abstract

Forest and land fires have become a national issue every year, especially in West Kalimantan. From 2015 to 2020, around 331,268.35 hectares of forest and land were burned in West Kalimantan. As a result of forest and land fires, the haze disrupts public health, the economy, and river, land, sea, and air transportation. As anticipation and prevention, the community and government monitor forest and land fires using the Forest Fire Monitoring System Application. The purpose of this study was to the User Experience (UX) evaluation for design improvement in the Forest Fire Monitoring System Application (SIPONGI) inWest Kalimantan. The method used was User Centered Design (UCD) and Website Usability Evaluation Tool (WEBUSE) to provide new design solutions in the form of a website prototype. The research methodology included a literature study of the SIPONGI application. The study used a sample of 25 respondents with different work backgrounds to represent the population using the SIPONGI application. The results of this study showed that usability points per attribute and category are superior after making UI/UX improvements using the UCD process in prototype form. In conclusion, using the UCD method is better if it is accompanied by the WEBUSE method in improving the design of an application.

Abstract

This research presents the development of a real-time classroom environmental monitoring system using edge computing and the MQTT protocol. The system is designed to monitor temperature, humidity, and illumination by utilizing an ESP32-based edge node equipped with DHT22 and BH1750 sensors. Data are processed locally and transmitted to an edge server running the Mosquitto broker, which stores the results and displays them through a web-based dashboard. Performance evaluation was conducted through experimental testing at distances of 5 and 10 meters, measuring delay and throughput using timestamp analysis and Wireshark traffic capture. The results show that the system operates functionally and maintains stable data transmission, with average throughput of 402.5 bps. However, the average delay of 1071.12 ms across both scenarios falls into the “poor” category based on TIPHON standards, indicating significant latency caused by Wi-Fi signal variability. Overall, the system successfully demonstrates the feasibility of edge-based IoT monitoring for learning spaces and provides a foundation for the development of smart classroom environments requiring continuous environmental supervision.

Abstract

Waste accumulation is a common problem caused by low public awareness of waste management and suboptimal waste handling by sanitation workers. Waste incineration can serve as a solution, but it has the potential to cause undesirable consequences if not properly supervised; therefore, a monitoring system capable of tracking the waste incineration process in real-time is necessary. With the rapid advancement of technology, wireless technology can be utilized to address this issue. However, most wireless technologies still rely on internet networks, making them less effective in areas with limited internet connectivity. Therefore, this study proposes the use of LoRa technology as a solution for data transmission without reliance on an internet network. The developed system can monitor waste incineration sites using MQ-2 sensors and flame sensors in real-time via a website, utilizing the LoRa SX1278 data transmission system. Implementation results show that the monitoring system can detect residual smoke and fire from waste incineration sites and monitor them up to a distance of 150 meters. Signal quality in LoRa SX1278 transmission is expressed in RSSI (Received Signal Strength Indicator) units, with an “excellent” signal category achieved up to a distance of 40 meters in the tests conducted.

Abstract

Purpose – This study aims to design and evaluate a secure reconnaissance platform that integrates Large Language Model (LLM) agents for dynamic tool orchestration with a layered cryptographic protection pipeline to accelerate penetration-testing information gathering while protecting sensitive artefacts. Design/methods/approach – The platform unifies Nmap, WHOIS, and theHarvester under an LLM controller that generates command-line parameters through schema-constrained orchestration. Each output is validated against a strict JSON schema before execution. The protection pipeline applies AES-256-GCM with envelope keys for confidentiality, HMAC-SHA256 hash chaining for tamper-evident logs, Ed25519 signatures for report-level non-repudiation, and Argon2id-derived session keys. Evaluation was conducted on three public domains across thirty runs each, measuring latency, cryptographic overhead, verification integrity, signature validation, and an internal CVSS-informed triage score. Findings - The prototype showed that automated reconnaissance and cryptographic auditability can be combined with limited performance cost. A full pass over untan.ac.id completed in 14.97 seconds and produced an internal triage-heuristic score of 78/100. Cryptographic operations added 312 ms on average, equal to about 2.08% of total latency. All hash-chain links were verified, and Ed25519 signatures were validated in 71 µs. Research implications/limitations – The findings support red-team and blue-team workflows requiring faster, auditable reconnaissance reporting. However, the evidence is limited to three public domains under one network condition; therefore, the results should be interpreted as feasibility evidence, not generalisable performance claims. The risk score is an internal prioritisation heuristic, not a validated severity instrument. Originality/value – The study contributes a secure LLM-orchestrated reconnaissance framework that integrates structured command orchestration with cryptographic safeguards for confidentiality, integrity, and non-repudiation.

Abstract

Perangkat Internet of Things (IoT) seperti ESP32, meskipun populer karena murah dan fitur Wi-Fi, memiliki keterbatasan sumber daya yang membuatnya rentan terhadap serangan siber. Penelitian ini menganalisis bagaimana serangan dapat dimplementasikan menggunakan 1 perangkat ESP32 dan dampak terhadap 1 perangkat ESP32 dari dua jenis serangan umum, yaitu Denial of Service (DoS) melalui ICMP Flood dan Address Resolution Protocol (ARP) Spoofing, dalam lingkungan Wireless Sensor Network (WSN) bertopologi star. Dalam penelitian ini, satu perangkat ESP32 diprogram sebagai penyerang untuk menyerang salah satu dari tiga perangkat ESP32 client lain yang terhubung ke sebuah server lokal melalui protokol WebSocket. Tujuan penelitian ini adalah untuk menganalisis pengimplementasian serangan, dampak performa perangkat target, dan dampak terhadap metrik Quality of Service (QoS) seperti latency, jitter, throughput, dan packet loss, serta kinerja perangkat (CPU load dan memori). Hasil penelitian menunjukkan bahwa serangan ARP Spoofing yang dilancarkan oleh satu perangkat ESP32 efektif dan dapat digunakan sebagai serangan DoS karena mampu memutus koneksi client target dari server dengan tingkat packet loss mencapai hampir 100%. Sebaliknya, serangan ICMP Flood dari satu perangkat ESP32 penyerang tidak berhasil mematikan perangkat target tetapi secara konsisten meningkatkan beban CPU-nya mencapai 17,63%. Penelitian ini membuktikan bahwa perangkat berdaya rendah seperti ESP32 dapat digunakan sebagai platform serangan yang efektif dalam jaringan lokal, menyoroti pentingnya keamanan pada lapisan jaringan bahkan di antara perangkat sejenis. Kata kunci: ESP32, Denial of Service, ARP Spoofing, Keamanan IoT, WSN.
