Abstract

Aquaculture plays a vital role in global food supply, contributing nearly 43% of the food consumed by humans. The rapid growth in aquaculture production demands a significant amount of electricity, which accounts for approximately 40% of the total energy costs. The primary energy sources in aquaculture used fossil fuels, it can be reduced by utilizing alternative energy sources. This research aims to develop a prototype of a floating net cage using an Internet of Things (IoT)-based water quality monitoring system powered by solar energy. The water quality parameters monitored in this study include temperature, pH, salinity, and dissolved oxygen levels. The sensors used for monitoring these parameters have undergone testing. The results indicate that the sensors can perform accurate measurements with over 90% accuracy. The solar panels installed in the system are capable of generating sufficient power to meet the operational demands, allowing the system to operate for approximately two days without sunlight. By maintaining well-controlled aquatic environmental conditions through IoT-based monitoring and control systems supported by renewable photovoltaic solar energy, environmentally friendly aquaculture operations can be conducted efficiently and productively. Ultimately, this leads to the production of high-quality aquaculture products, cost-effective operations, and the utilisation of eco-friendly energy sources.

Abstract

Whiteleg shrimp (Litopenaeus vannamei) is an important fishery commodity in Indonesia, but its success is strongly influenced by water quality, which can impact the health and immune system of the shrimp. Poor water quality has the potential to induce physiological stress in vannamei shrimp and disrupt their immune system, necessitating research to optimize water quality in shrimp aquaculture. This reseacrh employed a quantitative descriptive method to analyze data obtained through simple random sampling in vannamei shrimp ponds in Probolinggo, East Java. The water quality parameters measured included temperature, pH, DO, TSS, TDS, salinity, ammonia, and nitrate, while immune parameters such as THC, DHC, and phagocytosis activity were assessed. Canonical Correspondence Analysis (CCA) was used to analyze the relationship between water quality and immune parameters. The results indicated a significant influence of water quality on the immune parameters of the shrimp, providing valuable insights for more effective pond management. The findings of this research are expected to assist shrimp farmers in improving water quality and the immune system of vannamei shrimp, thereby reducing stress and enhancing productivity in sustainable shrimp aquaculture.

Abstract

In marine applications, the energy storage system (ESS) functions as the primary energy supply for fully electric propulsion vessels. During variable operation conditions involving pulsed propulsion load, the ESS employing monotype topologies are often oversized and can damage the cells. This study proposes a hybrid energy storage system (HESS) for an all-electric Seabus with a 10-year operational lifespan, with the objective of optimizing the storage system size to ensure longer operation than 72 minutes at a speed of 30 knots under variable conditions. The impact of the HESS system on installation cost and weight was thoroughly investigated. Some HESS configurations are presented, utilizing Lithium Iron Phosphate (LFP) as the high-energy (HE) cell and supercapacitors, Lithium Ion Capacitor (LIC), and Lithium Titanium Oxide (LTO) as three alternatives of the high-power (HP) cell. The HESS design predates a parallel full-active configuration with a rule-based energy management method that utilizes cut-off power between HE and HP cells. In this specific case, the LFP-LTO configuration is the optimal HESS design rather than the LFP-SC and LFP-LIC configurations, meeting all established optimization criteria and weight limitations. The study demonstrates that the HESS configuration can achieve 120 minutes of operation, which is 67% longer than the operation time of previous Seabus operations.

Abstract

The waters of Raja Ampat in Papua are one of the world's top maritime tourism destinations, attracting over 30,000 tourists annually since 2020. However, the challenging geographical conditions, such as shallow coral reefs, strong sea currents, and busy speedboat traffic, significantly increase the risk of maritime accidents. According to the National Disaster Management Agency (BNPB), from 2012 to 2024, six incidents in the area caused serious accidents, including vessel damage and injuries. This study aims to analyze the risks of tourist speedboat accidents in Raja Ampat using three complementary risk assessment methods: the Swiss Cheese Model (SCM), interviews, and questionnaires. The Swiss Cheese Model identifies gaps in several layers, such as Environment and Weather, Vessel and Safety Equipment, Skills and Competence of Operators, and Tourism Safety Management and Regulations. The analysis shows that the skills and competence of boat operators are significant weaknesses in accident cases, and it recommends that boat operators in Raja Ampat participate in SCRB (Survival Craft and Rescue Boat) training and certification programs

Abstract

Hydrodynamics of a floating structure is of interest from offshore and coastal engineers who develop the wave energy converters and utilize the marine space resources. Recently, Rim [1-3] proposed an exact DtN (Dirichlet-to-Neumann) artificial boundary condition in order to solve three-dimensional wave-structure interactions or wave motion over piecewise topographies numerically. This paper is concerned with another artificial boundary condition or so-called NtD (Neumann-to-Dirichlet) boundary condition in order to solve water wave diffraction and independent radiation by a buoyant body. A virtual cylindrical surface enclosing the floating body is chosen as a boundary on which an exact NtD map is analytically derived from a solution of the exterior subregion and then it is specified as a boundary condition in order to solve the interior problem. The present model shows good accuracy through the comparison with the DtN approach and suggests the escalated results for the effects of heading angle of incident wave and draft of a buoyant chamfer box.

Abstract

Parrotfish have an essential role in maintaining the balance and health of coastal and marine ecosystems, but the existence of coral reefs on Pulau Tikus as their habitat has been degraded, threatening the survival of these fish. This study aims to determine the abundance of fish in the Scaridae family based on coral reef cover and the relationship with coral reef cover. Sampling was conducted in February-May 2021 in the waters of Pulau Tikus Bengkulu. Reef fish observations used UVC (Underwater Visual Census), while coral reef cover used the LIT (Line Intercept Transect) method. The highest reef fish abundance was at station 1 at 0.06 ind/m2, while the lowest was at station 3 at 0.02 ind/m2. The highest percentage of coral cover was at station 1 at 70.44% and the weakest at station 3 at 8.18%. The relationship between the percentage of coral cover and parrotfish abundance strongly correlates with a value of R = 0.62.

Abstract

The previous Savonius wind turbine studies have proved that overlap modifications to conventional blades can improve turbine performance. With these conventional blades, the performance is less optimum because the drag force generated by turbine's rotation is still high. Based on this condition, this experiment is conducted by modifying Savonius wind turbine with overlap blades using Myring equation n = 1. Its blade profile is made half-elliptical to reduce drag force. Diameter and height of the turbine are 400 mm with 0.3 overlap ratio. The ratio of cylinder diameter (ds/D) is 0.4, and the ratio of cylinder center distance (S/d) is 1.7. Experiments are conducted by varying stagger angles of circular cylinder in front of returning blade are 45°, 50°, 55°, and 60° with velocity 5 m/s. The final results show that the best performance improvement of the turbine occurs at 60° stagger angle. The increase in torque coefficient is 4.95% and power coefficient is 20.16% to overlap Savonius wind turbine with myring n = 1 with no circular cylinder.

Abstract

The stress value of the piping system will change during operating conditions. The stress value affects the integrity of the piping system. Excessive stress will cause deformation and damage to the piping system. The operating condition parameters of the piping system are temperature and pressure. The High-Energy Piping (HEP) system is subjected to high pressures and temperatures, which can cause significant stresses on the piping components. So stress analysis needs to be carried out to ensure that the piping system has strength and flexibility. The Cold Reheat Pipe (CRP) steam line is one of the High-Energy Piping Systems in this steam power plant. CRP consists of CRP BS 130 and CRP BS 131. This paper is about evaluating the stress due to operating loads in 2024 (temperature, pressure, and remaining thickness) for steam lines on the high-energy piping system using the finite element method and refers to ASME B31.1. The output stress values in the piping system in this paper consist of stress due to sustained load, stress due to thermal load, and hoop stress. The CRP BS 130 modeling results show the maximum stress due to sustained load (166.6 kg/cm2), the maximum stress due to the thermal load (112.8 kg/cm2), and the maximum hoop stress (855.6 kg/cm2). The CRP BS 131 modeling results show the maximum stress due to sustained load (974.2 kg/cm2), the maximum stress due to the thermal load (123.5 kg/cm2), and the maximum hoop stress (938.9 kg/cm2). The results of the stress evaluation due to the operating load were still below the allowable stress and are still permitted by the ASME B31.1 Code.
