Abstract

The adoption of High Density Polyethylene (HDPE) as the primary material for boat structures has increased significantly in recent years. In response to contemporary challenges and to facilitate research requirements, Polytechnic of Bengkalis (POLBENG) constructed a research boat utilizing HDPE. Nevertheless, further research on the response of the HDPE structure to vibrations generated by the main propulsion engine remains insufficiently intensive. Therefore, a direct measurement of ship vibration is conducted utilizing vibration sensors, namely Witmotion WTVB02-485. Both inside and outside of the accommodation rooms, measurements were taken. By comparing the vibrational velocity's Root Mean Square (RMS) to standards established by the American Bureau of Shipping (ABS), a classification society, structural assessment was evaluated. Furthermore, resonance events were discovered by comparing the Blade Passing Frequency (BPF) with the recorded peak frequency output. The HDPE structure seems to be dependable, according to the measurement findings at both locations. The RMS of 0.020 mm/s and a peak frequency of 33.31 Hz were recorded inside the accommodation area, whereas 0.013 mm/s and 31.52 Hz were recorded outside.

Abstract

The transformation of aquaculture through digital technologies has become increasingly essential to enhance sustainability, efficiency, and competitiveness in shrimp farming. Despite its importance, the challenge of determining which regions should be prioritized for digital adoption remains unresolved, particularly in contexts with diverse production and economic conditions. This study introduces the Analytical Hierarchy Process (AHP) as a multi-criteria decision-making tool to evaluate and prioritize coastal districts in Central Java, Indonesia, for smart aquaculture development in Litopenaeus vannamei farming. AHP integrates indicators of production potential, economic feasibility, and price competitiveness into a unified ranking framework, producing clear differentiation across districts. The results highlight Cilacap, Kendal, Brebes, Purworejo, and Rembang as priority areas for early adoption of digital innovations such as IoT-based monitoring, AI-driven disease prediction, and traceability platforms. This research contributes to the operationalization of the AHP algorithm for aquaculture decision-making, contextualization of the global digital transformation framework in the Indonesian shrimp sector, and demonstrates the robustness of multi-criteria prioritization for policy planning. Although the precision of the results may be limited by the scope of the available data, the study confirms the significant role of AHP in guiding evidence-based, scalable, and adaptive strategies for advancing smart aquaculture.

Abstract

This research explores the integration of Internet of Things (IoT) technology with MEMS (Micro Electro Mechanical Systems) sensors and piezoelectric technology to enhance the efficiency and operational sustainability of devices. IoT connects physical devices to the internet to collect and exchange information and has become an integral part of Industry 4.0. The main components of IoT include physical objects, communication channels, software, operations, and data. In this study, IoT development focuses on the maritime sector with the application of MEMS sensors, piezoelectric technology, ocean current speed, and turbines. The use of piezoelectric technology allows devices to operate autonomously by harvesting energy from vibrations and pressure, further improving the efficiency of IoT devices. Experimental results show that in an open circuit, the highest average voltage at a speed of 1.1 m/s reached 0.019606 mV (capacitor) and 0.0056 mV (non-capacitor). In a closed circuit, with one non-capacitor piezoelectric, the average voltage was 14.762 mV and the average current was 0.0027 mA, producing a power output of 0.0398 mW. With four non-capacitor piezoelectrics, the average voltage reached 33.174 mV and the current was 0.0044 mA, producing a power output of 0.0146 mW. Meanwhile, with one capacitor piezoelectric, the average voltage was 4.947 mV and the current was 0.0023 mA, producing a power output of 0.01138 mW. With four capacitor piezoelectrics, the average voltage was 16.627 mV and the current was 0.0036 mA, producing a power output of 0.05986 mW. These results indicate that the piezoelectric turbine mechanism has significant potential as a reference for the development of future renewable energy technologies. The implementation of this technology allows IoT and MEMS devices to function autonomously and sustainably, supporting applications in various sectors including maritime and industry.

Abstract

Offshore platforms are large structures designed to accommodate personnel and equipment required for drilling wells in the seabed, extracting oil and/or natural gas, processing the resultant fluids, and transporting them to land by shipping or pipelines. Jacket platforms are fixed structures anchored to the seabed with piles to ensure stability against wind, wave, and current forces in the marine environment. The gradual deterioration of the fixed platform over time during operations becomes a subject of concern. The study aims to carry out a structural safety assessment (SSA) of an existing offshore platform in the Gulf of Guinea (GOG) by analyzing the reliability, risk index, safety margins, and structural integrity of the platform. A detailed investigation of design specifications, material characteristics, and environmental loads assessed the structural reliability and risk margins. A risk matrix prioritizes major structural concerns, resulting in specific recommendations for mitigation, repair, and maintenance. The platform's reserve strength ratio (RSR) was examined to build long-term structural integrity, safety, reliability, and environmental resilience strategies. The platform's safety and structural integrity were assessed using Ultimate Strength Assessment (USA) and Reliability–Risk Assessment (RRA) methods. According to the findings, corrosion, fatigue, seabed scour, subsidence, overload from environmental forces (wind, waves, currents, and earthquakes), collisions, crane accidents, explosions, falling objects, fires, leaks, accidental discharges, towing incidents, and well-related damage are the main threats to the jacket platform. The extent of corrosion and the associated probabilities of failure (POF) and reliability of the platform’s four jacket legs were calculated. The corrosion losses for Legs 1, 2, 3, and 4 were found to be 4.577%, 3.462%, 3.346%, and 4.039%, respectively. Leg 1 exhibited the highest POF (0.04577) and the lowest reliability (0.95423), whereas Leg 3 showed the lowest POF (0.03346) and the highest reliability (0.96654). The overall reliability factor of the platform was determined to be 1.0401, which, although lower than the safety load factor of 1.25, still indicates a level of structural safety. According to the risk matrix, all four jacket legs (L1–L4) fall within the “Medium” risk category for structural failure, suggesting the risk is within acceptable limits. To address corrosion-related risks specifically, cathodic protection is recommended as an effective mitigation and maintenance strategy. The Ultimate strength analysis produced an Ultimate strength of 3000 kN for a design capacity of 1250 kN, resulting in an RSR of 2.4, which is more than the minimum safety criterion of 1.50 for a manned structure, indicating that the jacket platform structure is SAFE and Fit-for-Purpose.
