Abstract

Gempa bumi dapat menimbulkan bahaya besar bagi manusia dan menyebabkan kerusakan infrastruktur. Gempa terbagi menjadi gempa tektonik akibat pergeseran lempeng tektonik dan gempa vulkanik akibat aktivitas magma sebelum letusan gunung berapi. Untuk mengurangi risiko, dikembangkan sistem deteksi gempa otomatis menggunakan sensor SW-420, mikrokontroler Arduino Uno, serta buzzer dan LED sebagai alarm. Sensor SW-420 mendeteksi getaran tanah dan mengirimkan data ke Arduino Uno. Jika nilai getaran melampaui ambang batas 6000 (setara 4 Skala Richter), sistem secara otomatis mengaktifkan alarm berupa buzzer dan LED untuk peringatan dini. Data getaran ditampilkan di Serial Monitor Arduino sebagai alat pemantauan. Dengan peringatan cepat, sistem ini diharapkan membantu evakuasi lebih awal, meminimalkan risiko cedera dan kerugian. Sistem dirancang menggunakan metode waterfall, meliputi analisis kebutuhan, desain sistem, pengkodean, pengujian, dan pemeliharaan. Pengujian menunjukkan sensor mampu mendeteksi perubahan getaran signifikan, seperti lonjakan dari 2655 ke 4932 dalam satu detik. Untuk pengembangan, disarankan menambahkan modul GPS untuk menentukan lokasi gempa secara real-time dan menggunakan sensor yang lebih akurat guna meningkatkan efektivitas mitigasi bencana.

Abstract

Indonesia shares borders with Papua New Guinea, Malaysia, and Timor Leste, where border markers often face displacement or disputes due to challenging and inaccessible terrain. This research develops a waypoint navigation system on a quadcopter, integrating computer vision to enhance the detection and monitoring of border markers. The system leverages the Robot Operating System (ROS) as middleware for seamless integration and control, while a camera detects ArUco markers placed on boundary markers. Image processing, implemented using OpenCV integrated with ROS, facilitates efficient data conversion. The quadcopter autonomously navigates to target coordinates based on marker detection, with an average percentage error of 3.3% for the X-axis and 2.5% for the Y-axis. Tests showed the system could detect a 40x40 cm marker from a height of 5 meters up to a distance of 14 meters, with an average position error of 3.75%. The communication range was effective up to 150 meters before timing out. Despite the computational limitations of the Raspberry Pi hardware, the system demonstrated efficiency, scalability, and ease of deployment. Future research will focus on hardware enhancements, the exploration of advanced image processing methodologies, improved camera resolutions, and the extension of communication networks to support deployment in national boundary monitoring operations.

Abstract

The development of a data acquisition and control system based on modern technologies plays a crucial role in supporting aquatic environmental exploration using Unmanned Surface Vehicles (USVs). This project aims to design and implement a command-and-control unit capable of integrating water survey instruments with microcontroller-based sensors, targeting the real-time display of depth data, GPS location, and graphical visualization on an Smartphone application. The system employs the ESP32 module as the bridge between USV sensors—such as a single-beam echo sounder for depth measurement and a GPS module—and the user application. Wi-Fi connectivity is utilized for fast and efficient data transmission between the USV and the mobile interface. In this project, the Arduino IoT Cloud platform is adopted to simplify the integration of real-time data into the user interface, eliminating the need to develop an application from scratch. The system is designed to be cost-effective, portable, and user-friendly. This project is expected to demonstrate the system’s capability to process sensor-acquired data, control the USV’s movement direction, and display the results in numerical and graphical formats on the user's Android device in real time

Abstract

Ocean observation increasingly relies on Unmanned Surface Vehicles (USVs) for wide-area maritime data collection, yet existing Ground Control Station (GCS) systems remain limited by desktop-based accessibility constraints, high-latency HTTP communication, unoptimized relational databases, and the absence of integrated oceanographic sensor visualization. This study aims to design and develop a web-based GCS that unifies telemetry monitoring, bidirectional remote control, CTD and ADCP sensor visualization, and waypoint-based mission planning within a single browser-based interface. The system was developed using the Rapid Application Development (RAD) methodology, with MQTT and WebSocket adopted for low-latency communication and PostgreSQL with TimescaleDB for time-series data management. Functional testing confirmed that all core features operated correctly. Performance evaluation under 4G-LTE field conditions showed an average command round-trip latency of 178 ms and end-to-end monitoring latency below 250 ms. TimescaleDB hypertable conversion improved write throughput by 2.5×, reduced long-range query latency by 3.75×, and achieved a storage compression ratio of 875×. The proposed architecture provides a replicable reference for web-based USV GCS development across ocean observation applications.

Abstract

This study presents the design and implementation of an independent battery and lost-link fail-safe module to improve the navigational safety and operational reliability of Unmanned Surface Vehicles (USVs). Previous studies on USV fail-safe systems mainly focused on battery monitoring or communication recovery separately and generally relied on the main onboard controller or autopilot system. Such approaches may reduce system reliability when the primary controller experiences malfunction or communication interruption. To address this limitation, the proposed system integrates a Jetson Orin Nano, a CUAV autopilot, and an independent ESP32-based monitoring module capable of autonomously monitoring battery and communication conditions. Communication reliability is evaluated using MAVLink heartbeat signals, while battery condition is assessed using a progress-based energy estimation method to predict mission feasibility according to the remaining battery capacity and mission progress. When abnormal conditions such as low battery or communication loss are detected, the system autonomously activates fail-safe actions, including return-to-home and loiter modes, to prevent mission failure and vehicle loss. Experimental results show that the proposed system achieves a voltage measurement accuracy of 99.87%. In addition, the fail-safe mechanism successfully detects low battery conditions within 2.5–3.0 seconds and communication loss within 6–15 seconds, demonstrating improved USV operational safety and reliability.

Abstract

Waste is a real problem and will continue to increase as the human population grows. The increase in waste will have a negative impact on the environment and health if not managed properly. The process of handling household waste is still limited to collection and disposal carried out by the local Sanitation Service. In this case, recycling household waste is needed to reduce environmental impacts and improve economic and social welfare in the community. However, the problem that is often faced for this recycling process is the initial processing which includes sorting and crushing waste. This research aims to produce an efficient and appropriate household waste sorting machine design, this waste sorting machine design is useful for separating household waste that is organic and inorganic.

Abstract

Indonesia’s maritime sector faces rising pressure to decarbonize ships and ports while maintaining safety and competitiveness. This paper examines how green marine technologies can be embedded into maritime vocational education so graduates are ready for shipboard and port-side sustainability initiatives (energy efficiency, emissions reduction, waste management, and alternative energy systems). An exploratory mixed-method design was used: semi-structured interviews with nine stakeholders (industry practitioners, maritime educators, and recent graduates) were complemented by a simple stakeholder rating instrument to assess curriculum integration, sustainability awareness, and industry relevance. Thematic analysis identified recurring needs and implementation constraints, while the ratings helped prioritize actions. Findings indicate that sustainability topics are present but unevenly distributed across courses and often lack measurable competency targets. Project-based learning and case studies were perceived as the most effective approaches, especially when supported by simulator/lab facilities and industry co-teaching. The strongest gap lies in translating regulations and green-technology concepts into practical marine-engineering tasks and assessment rubrics. The paper proposes priority actions for curriculum owners: competency mapping to green shipping operations, structured industry feedback loops, and incremental upgrading of learning infrastructure. These steps can strengthen graduate employability and accelerate sustainable practice adoption in the maritime industry.

Abstract

This study presents the development and performance evaluation of an autonomous waypoint navigation system for a catamaran-type Unmanned Surface Vehicle (USV). The proposed system enables autonomous waypoint-following missions through real-time position monitoring, heading control, telemetry communication, and mission execution. The navigation system was implemented on a catamaran-type USV platform equipped with a companion computer, autopilot controller, GPS module, inertial sensors, and dual-thruster propulsion system. To evaluate navigation performance, experiments were conducted in both simulation and real-world environments. The performance assessment was based on waypoint error and heading error during autonomous waypoint-following missions. Experimental results demonstrated that the proposed system successfully executed autonomous navigation missions in both testing environments. The simulation experiments achieved a mean waypoint error of 0.49 m and a mean heading error of 4.21°, while the real-world experiments produced a mean waypoint error of 1.15 m and a mean heading error of 10.8°. Although larger navigation errors were observed during real-world operation due to environmental disturbances and positioning uncertainty, the USV successfully completed all assigned waypoint missions. These results demonstrate that the proposed navigation system provides reliable autonomous waypoint-following performance and supports maritime monitoring and inspection applications.

Abstract

Unmanned Surface Vehicles (USVs) are increasingly deployed due to technological advancements, yet their physical security remains significantly under-explored. While anti-theft frameworks are widely adopted for land vehicles, these systems rely on passive anti-theft mechanisms—alerting the owner about the theft—and failed to prevent the physical removal of the asset from the threat. To address this critical gap, this study proposes an active anti-theft system for USVs with a dual-layer detection mechanism utilizing spatial geofencing and physical attitude anomaly detection. The system employs an on-board edge computing that autonomously triggers a closed-loop Return-to-Launch (RTL) maneuver upon detecting a geofence breach, while simultaneously transmitting real-time telemetry update to a Web-Based Ground Control Station (Web-GCS). Testing across controlled and real-world environments demonstrated that the system reliably executes autonomous return protocols with low-latency communication. By transitioning asset protection from passive anti-theft to active anti-theft, this multi-layered framework establishes a novel foundational framework for physical security in autonomous vessels.
