Abstract

The waters of Banten Bay have abundant resources of small pelagic fish. Anchovies, mackerel, Shortfin scad, goldstripe sardinella, selar fish, mullet, and lemuru are small types of pelagic fish that can be found all year round in the waters of Banten Bay. Based on its abundant potential, however, its utilization is still inefficient because most local fishermen still use traditional fishing methods, which result in low catches and incomes. The purpose of this study is to develop a website-based system to determine the Fishing Potential Zone (FPZ) in the waters of Banten Bay by utilizing sea surface temperature (SST) and chlorophyll-a data from Aqua MODIS satellite imagery in 2023. Data processing is carried out with SeaDAS and ArcGIS software to determine FPZ points that are implemented in the form of a website, namely FishZone Mapper. The FishZone Mapper website is designed to provide information that can be easily accessed by fishermen, researchers, and other stakeholders to improve fishing efficiency. The results showed that there was a significant difference in the number of FPZ points in the western and eastern seasons, which affected fishing strategies.

Abstract

Kalimantan Institute of Technology (ITK), established on October 6, 2014, in Balikpapan, East Kalimantan, currently lacks adequate canteen facilities, compelling the academic community to seek meals off-campus. This study aims to design a new canteen facility to be constructed above the campus reservoir, focusing specifically on the structural and roofing systems. The planned canteen is expected to fulfill the food and beverage needs of students, lecturers, and staff, while also serving as a hub for social interaction. Our research methodology incorporates both qualitative and quantitative approaches. The project phases encompass detailed load analysis, structural modeling, internal force analysis, and a thorough plumbing design. Structural design adheres to the relevant Indonesian National Standards (SNI) for reinforced concrete structures and earthquake resistance. The substructure utilizes deep foundations adapted to local soil conditions, while the superstructure comprises reinforced concrete elements and a steel roofing system. Structural analysis results indicate the use of beams B1 (500×300 mm) and B2 (400×200 mm), circular columns K1 (D600 mm), and slab thickness of 120 mm. The roof structure consists of IWF rafters (300×150×6.5×9 mm), HB columns (300×300×10×15 mm), and CNP 200–16. This integrated design demonstrates a feasible and sustainable approach to infrastructure development on water-saturated soils.

Abstract

This research presents a dynamic system modelling approach for predictive maintenance of ship auxiliary engines using vibration variables. The model integrates key mechanical components—piston, crankshaft, camshaft, valve train, and timing gear—based on the specifications of a Yanmar TF85 diesel engine. Each subsystem is modelled using a multi-degree-of-freedom (MDOF) state-space framework to represent vibrational and structural dynamics. Simulations are carried out in MATLAB/Simulink under various engine operating conditions, including normal operation at high, medium, and low RPMs, as well as fault scenarios such as damping degradation in the piston and crankshaft. A fuzzy logic system is employed to interpret the vibration data and determine the impact level for each condition. The results indicate that under normal conditions, the engine maintains stable vibration levels, while faults lead to significant increases in velocity RMS values and impact severity. Disturbances in the piston result in dominant amplitude changes, while crankshaft faults affect the frequency propagation throughout the system. These findings confirm that the proposed model can effectively detect early mechanical deviations and support the implementation of predictive maintenance strategies for marine diesel engines.

Abstract

The dredging industry's dynamic and high-risk operational environment makes its safety culture a critical factor in preventing occupational accidents. However, the complex interplay between different dimensions of safety culture in such a unique, project-based context is not yet fully understood. This research aims to develop and empirically test a structural model that explains the causal relationships among the nine core dimensions of the Safety Model Canvas and evaluates the influence of Safety Observation program within this framework. This study employed a quantitative approach using Partial Least Square Structural Equation Modeling (SEM-PLS). Data were collected from a major Indonesian dredging company through 50-item questionnaires administered to 95 employees and an analysis of 595 formal Safety Observation reports. A model with 12 hypothesized paths was tested to validate the theoretical framework. The analysis confirmed the model's validity, with 8 of the 12 hypotheses being statistically significant. The findings reveal that the Safety Observation program significantly enhances both Engagement & Involvement and Information & Communication. A robust operational pathway was identified where proactive leadership fosters worker engagement, which in turn builds responsibility. However, the model also uncovered a critical systemic weakness in the organizational learning process, indicating a failure to effectively translate safety information into enhanced worker competence. This study contributes a validated causal model of safety culture, offering significant theoretical and practical insights for safety management in project-based maritime industries.

Abstract

Solid waste management is a significant urban issue in Indonesia. This is exacerbated by rapid population growth and urbanization, which are not accompanied by sound waste management practices, such as a lack of infrastructure and widespread illegal dumping. This paper presents a data-driven methodology for analyzing trash generation patterns and identifying infrastructure requirements using a Geographic Information System (GIS). The goal is to create a data-driven strategy for identifying optimum Waste Collection Locations (WCPs) in order to improve service efficiency and reduce environmental impact. The study results show that Lhokseumawe City produces 530 m³ of waste daily. Therefore, Lhokseumawe City requires 44 strategically located waste disposal sites, taking into account existing illegal dumping locations and population density. An additional 21 garbage trucks are also needed to manage the urban waste generation volume. This indicates a significant shortage of waste management facilities to serve the population. This study presents a practical plan for local governments, including optimal WCP locations and designs, to achieve the SDGs goal of becoming a sustainable city.

Abstract

This research is a case study of the Mid-Water Buoy (MWB) structure on the subsea hose string SPM #4 after the installation of New PLEM C, or in other words in conditions where the subsea hose string (including MWB) has been connected to New PLEM C. MWB is one of the ancillary components of the subsea hose string, which has the main function as a buoy to keep the entire subsea hose string at a safe distance to the seabed. By replacing the old PLEM-C with the New PLEM-C, the dynamic motion of the subsea hose when connected to the New PLEM-C will also be different compared to the dynamic motion when connected to the old PLEM-C. The objective of this study is to analyze the fatigue life of the MWB structure after the use of New PLEM-C. As the main input for fatigue analysis, cyclic load analysis acting on the MWB structure is carried out based on a deterministic approach through time domain simulation and continued with the calculation of the number of cycles with the rainflow cycle counting method. For local stress analysis in the critical area of the MWB structure, the hotspot stress method is carried out through the Finite Element Method (FEM) which refers to DNV-RP-C203. Furthermore, the fatigue life calculation is carried out by applying the Palmgren-Miner rules and utilizing the S-N Curve. From a series of analyses that have been carried out it was found that the lowest fatigue life value for the MWB structure is occurs at PART B1 (the part of the MWB connected to the Subsea Hose STRING B – Upper) with a value of 145.93 years and with an annual damage ratio of 0.0069 for the Connection between the Vertical Stiffener and the Pipe.

Abstract

The Natuna Sea is considered a prime maritime area for Indonesia, bearing strategic and defense significance, besides its turbulent sea conditions demand warships to adopt or be provided with efficient and stable hull forms. Thus, this study is intended to investigate the most appropriate bow designs for a corvette warship operating in the Natuna region. Three types of bow are compared: a conventional V-hull, sloped bow, bulbous bow and axe bow. Comparison through Computational Fluid Dynamics (CFD) simulation, validated with Holtrop and Savitsky empirical methods, at the speed of 30 knots. Principal dimensions of the corvette were obtained through regression analysis from 20 other warships that belong to the same class. Results reveal that the axe bow has the smallest resistance, that is, 365.18 kN from Holtrop method and 374.27 kN from CFD in contrast to 384.43 kN owing to conventional bow design. It also fulfills all criteria of operation performance and fuel efficiency. Hence, it is considered the best alternative for corvette deployment into the Natuna Sea.

Abstract

To ensure the continuity of delivering crude oil from the Central Plant to the Floating Storage and Offloading (FSO), PHE ONWJ plans to replace existing pipelines and Pipeline End Manifolds (PLEM) in order to enhance the integrity and reliability of the Marine Terminal facilities. The configuration changes resulting from the installation of new pipelines and PLEM alter the dynamic interactions between the subsea hoses connected to the New PLEM and Old PLEM, leading to different load conditions on the new PLEM structure. Considering the importance of PLEM in crude oil transfer process from wells within the ONWJ working area to the FSO, thus this research will conduct a fatigue analysis of the Pipeline End Manifold (PLEM) due to cyclic tension loads from subsea hoses. The objective of this research is to predict the fatigue life of New PLEM A structure by applying Palmgren-Miner Rule. The study will begin with an analysis of the mooring lines system and subsea hoses connected to the new PLEM to identify the cyclic tension loads acting on the structure. The analysis was performed using time domain simulation with output in the form of a tension time history. The results of the time tension history will then be processed to find the tension range cycle value using the Rainflow cycle counting method. Furthermore, to assess the stress distribution caused by cyclic loads from the subsea hoses, a local stress analysis will be performed using hotspot stress method by finite element analysis (FEA) which refers to DNV-RP-C203. The result of hotspot stress analysis will be used for the fatigue life calculation of the New PLEM A structure. The analysis results show that the lowest fatigue life of the new PLEM A structure occurs at the connection between pipe support and skid, with a fatigue life value of 17.63 years and a damage ratio of 0.0113. In contrast, the connection between the elbow pipe and flange exhibits a significantly higher fatigue life of 499.38 years and a damage ratio of 4 × 10-4

Abstract

Mahakam Ulu Regency's landscape is dominated by tropical rainforest, with transportation access heavily reliant on river routes. The region is home to 245 rivers, ten of which are classified as major rivers and are distributed across all sub-districts. The Mahakam River serves as the main artery for community activities, including the emergency transport of patients. Nevertheless, serious challenges persist due to limited healthcare infrastructure and inadequate medical transport, which hinder the timely treatment of patients. Currently, there are no water ambulances specifically designed for emergency medical services, leading to delays and increased risks of patient morbidity and mortality.The aim of this study is to develop a water ambulance vessel designed to serve as a dedicated river based medical transport in Mahakam Ulu. A parent ship design approach was applied in the development process. The principal dimensions defined in this study are as follows:Length Overall (LOA): 10.5 m,Beam (B): 3.15 m, Depth (H): 1.35 m, Draft (T): 0.65 m, Service Speed (Vs): 20 knots, Accommodation: 10 crew and passengers. Keywords- Mahakam Ulu, Mahakam River, Water Ambulance, Parent Ship Design

Abstract

Fuel oil is a critical input for seine net fishing in Palabuhanratu, yet its rising cost imposes a heavy burden on fishers and boat owners. Although fishers intuitively adjust engine power to reduce fuel use, the effectiveness of these practices remains unclear due to limited data. This study examines fuel consumption patterns of seine net boats and explores potential savings strategies. Data were collected on daily fuel use, vessel speed, trip duration, and operating distances across boats with engines of different ages. Results show that fishing trips follow eight distinct phases: preparation, outbound steaming, setting, hauling, fish hunting, resting, inbound steaming, and berthing. The highest fuel use occurs during fish hunting as well as outbound and inbound steaming, where high speeds and long durations dominate. Engine age strongly influences efficiency: a 6-month-old engine achieved a specific fuel consumption (SFC) of 328.42 g/kWh, compared to 499.33 g/kWh for a 7-year-old and 873.41 g/kWh for a 12-year-old engine. Simulation of reduced speeds during fuel-intensive phases suggests potential savings of 1.7%–21.7%, without compromising operational feasibility. These findings highlight the importance of managing vessel speed and engine condition to optimize fuel efficiency in seine net fisheries.
