Abstract

An oscillating water column (OWC) is a type of power generation device that converts ocean wave energy into electrical energy. The motion of ocean waves forces air through the OWC column and drives a rotor connected to a generator to produce electricity. The Wells turbine is a typical kind of rotor for OWC system. The performance of the Wells turbine can be influence by various factor, such as its geometry. Over the time, various research have been conducted to enhance the Wells turbine design. This study aims to analyze the impact of blade profiles on an 8-bladed Wells turbine’s performance using the Computational Fluid Dynamics (CFD) method. A full-domain with multiple reference frame (MRF) approach is applied to represent the rotating flow of the turbine. The flow is solved using Reynold Average Navier-Stokes (RANS) solver accompanied by shear stress transport turbulunce model to capture the boundary layer near the wall. In this study, some blade profiles including NACA 0012, NACA 0015, and NACA 0018, with chord lengths of 100 mm, 125 mm, and 150 mm, are examined. The results of this study reveal that the NACA 0018 blade profile with a 150 mm chord length improves the torque coefficient by 36.28% and the power coefficient by 1.04% compared to other configurations.

Abstract

The objective of this research is to design a catamaran tourist ship that incorporates green technology. To achieve this, the main dimensions of the ship will be determined using the linear regression method, based on existing data from similar vessels. The empirical data from existing vessels serves as the foundation for the analysis and prediction, thereby enabling the identification of relationships and patterns between the key variables, including length, width, draft, displacement, and passenger capacity. The linear regression method offers several advantages, including simplicity, ease of interpretation, and efficiency in the use of resources. As a result, it is an effective tool for initial analysis before the application of more complex methods. The R2 value has an average result above 90 percent, so the data can be considered good and valid. The innovative aspect of the design of this tourist ship is the utilisation of data pertaining to existing vessels that have demonstrated optimal performance in their role as tourist ships. The use of existing data not only helps reduce the risk of errors in the design of new vessels but also ensures that the design is efficient and compliant with operational needs and safety regulations. This research confirms the importance of a data-driven approach in the design of environmentally friendly and efficient ships. In the context of ship design and operation, displacement represents a pivotal parameter in linear regression analysis. An understanding of the relationship between displacement and ship performance allows for more accurate predictions regarding speed, fuel consumption, stability, and draft. This allows for the design of ships that are more efficient, stable, and safe, and optimized under a variety of operational conditions.

Abstract

Marine ecotourism in Bali is vital for integrating environmental conservation, cultural preservation, and community empowerment. Despite its potential, sustainability efforts face significant challenges, including coral reef degradation, coastal erosion, marine pollution, and gaps in policy implementation. This study aims to evaluate the application of the Tri Hita Karana philosophy as a holistic framework to address these challenges in Bali’s marine ecotourism sector. A literature review method was used, synthesizing peer-reviewed studies, government reports, and case examples from major ecotourism sites such as Nusa Penida and Perancak Mangrove Forest. The results demonstrate that the Tri Hita Karana philosophy effectively integrates ecological, social, and cultural dimensions. Successful initiatives include coral reef restoration and community-based conservation programs that enhance biodiversity and support local economies. However, challenges such as inconsistent policy enforcement, visitor overcapacity, and infrastructure pressures remain significant. This study concludes that adaptive management strategies, including capacity assessments, collaborative governance, and technology integration, are essential to ensure the long-term sustainability of marine ecotourism in Bali. The findings contribute to the global discourse on sustainable tourism, offering Tri Hita Karana as a model adaptable to other culturally rich and ecologically sensitive regions.

Abstract

A Traditionl Wooden ship in North Penajam Paser is built without initial calculation to predict the resistance that will occur based on the shape of the hull. The ship is built solely based on the main dimensions and the number of engines to be installed, without considering the optimal hull shape. The hull shape is an important component in supporting the hydrostatic performance of a ship. Planning the hull's shape affect the ship's resistance value and ultimately impacts the ship's engine power requirements. The purpose of this research is to obtain the resistance value of the existing ship and determine the hull shape with a lower resistance value through computer-based simulations. The computer simulation approach based Holtrop method is used to determine the position of the LCB point based on the hull shape. Then, it examine the effect of the LCB position on the ship’s resistance of the hull shape. The hull shape simulation was conducted without changing the ship’s main dimensions. The simulation result show that the position of the LCB on the existing hull shape is 8.514 m from the AP, with a ship resistance value is 7.4 kN. Meanwhile, the optimum hull shape was found when the location of the LCB point was moved 0.1 m forward from its initial position (model 4). The resistance value in Model 4 decreased by 3.8% compared to the initial resistance value. In addition to model 4, models 2 and 3 also reduced the ship's resistance value, with changes of 0.9% and 2.1%, respectively. Furthermore, this optimal hull shape can be developed in the next analysis stage, such as ship structure planning and other design analyses.

Abstract

Muara Angke Port, one of Indonesia's busiest fishing hubs, faces significant challenges due to dynamic water conditions and heavy vessel traffic, including waves, currents, tides, and vessel interactions. These conditions impact the motion response of fishing vessels, affecting their stability, maneuverability, and operational safety. This study aims to analyze the motion response of fishing vessels operating, focusing on environmental factors influencing vessel operations. A comprehensive analytical approach is employed, including the panel method for seakeeping analysis. Specific seakeeping criteria for fishing vessels, as proposed by Tello, are applied to assess vessel performance in various sea states. The findings indicate that fishing vessels can operate effectively in sea states with wave heights up to 3 meters, or sea state 5 and below. These results provide valuable insights into how fishing vessels respond to environmental challenges at Muara Angke Port, offering recommendations for improvements in vessel design. The study emphasizes the importance of developing operational strategies to reduce accidents and enhance the sustainability of the fishing sector, while supporting the long-term resilience of Indonesia's fisheries industry.

Abstract

Glass strain carp (Cyprinus carpio) is highly demanded by farmers due to its delicious, dense meat and fewer spines. To meet the increasing demand for carp, it is necessary to improve the efficiency of aquaculture. The season is known to stimulate one hormone production. The purpose of this study was to determine the effect of season (rainy and dry seasons) on reproductive hormones (follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone and estrogen, and interstitial cell-stimulating hormone)) in C. carpio glass strain. Idi research was conducted using the descriptive method by rearing fish in different seasons (rainy season and dry season). The results showed that the reproductive hormone of C. carpio strain glass increased during the rainy season. During the rainy season, changes in the environment and water flow patterns are detected by the fish's sensory system. The results showed that the highest hormones in a row were: ICSH hormone (12.82 pg/mL), FSH hormone (male: 3.73 ng/mL; female: 12.10 ng/mL), LH hormone (12.48 MIU/ml), testosterone hormone (9.27 ng/mL) and estrogen hormone (21.84 ng/mL). Further research is needed to observe the growth and abnormality of fish larvae produced in different seasons.

Abstract

Piezoelectrics are materials that can produce electrical voltage when subjected to mechanical stress. This unique property makes piezoelectrics widely used in various applications, such as sensors, actuators, and transducers. One important factor that can influence piezoelectric performance is the tilt angle. The tilt angle is defined as the angle between the piezoelectric surface and the direction of the applied force. This research aims to optimize the tilt angle of immersed piezoelectrics on a laboratory scale. Using the experimental method, this research was carried out using piezoelectric PVDF. Piezoelectric PVDF was chosen because it has good piezoelectric properties and is easy to obtain. Experiments were carried out by applying mechanical force to the piezoelectric PVDF with various tilt angles. Experimental results show that the optimal tilt angle for submerged piezoelectric PVDF is 90 degrees with a value of 7.46196 milliVolts at a flow speed of 1.2m/s. At this tilt angle, the piezoelectric PVDF produces the highest electrical voltage. The results of this study indicate that the optimal tilt angle for sunken piezoelectrics is 90 degrees. This could provide a basis for the development of more efficient and high-performance piezoelectric designs.

Abstract

Material procurement in the shipping industry accounts for 2/3 of the total production cost. PT.PMP is a company that focuses on the shipbuilding industry including Ship Design, Ship Building and Ship Repair. In the implementation of material procurement, there are often delays in the delivery of materials from suppliers resulting in delayed production time. Material inventory in the warehouse is sometimes insufficient to meet production needs. In the Pre-Order system, the company must ensure the availability of prepared planning items, but the Company sometimes faces a shortage of raw materials which results in delays in the delivery of promised goods. Material Requirement Planning (MRP) is a method used to organize and plan material orders. The purpose of this study is to determine the material planning strategy using the Lot for Lot method and the Economic Order Quantity method comparison between efficient methods at PT.PMP and to determine the efficiency results of the comparison between the Lot for Lot (LFL) method, Economic Order Quantity (EOQ) and the existing method at PT.PMP. The materials analyzed are Plate and Profile in the New Building Tugboat Project. The results obtained from the inventory cost research that the Lot for Lot method is 28%, the Economic Order Quantity method results in an inventory cost of 29% and the company method that is still being applied results in a high cost of 43%. The Lot for Lot method is more efficient by 15% than the existing method applied by the company.
