Abstract

Building heating, ventilation, and air conditioning (HVAC) systems are among the most critical facilities with the most significant energy consumption. This article is based on the issues faced by PT X regarding the importance of visual analytics in energy audits and the performance evaluation of water-cooled chillers and cooling towers. The research methodology used is descriptive qualitative with a quantitative approach, where primary data is obtained based on observations of the machines owned by PT X. The approach taken involves the application of spreadsheets as a system for processing operational data and Looker Studio for real-time data visualization, aimed at understanding performance and energy consumption. The research results show that visualization with the Looker Studio platform provides a solution for PT X to improve the efficiency and effectiveness of the company's performance. In addition, the analysis conducted over six months on the coefficient of performance of a 2,000 TR water-cooled chiller showed a highest value of 21.5 and a lowest value of 13.31, while the highest efficiency of the cooling tower reached 98% and the lowest was 74%.

Abstract

As cities grow, the demand for energy increases, necessitating a corresponding increase in energy supply. Since urban areas consume the majority of the world’s energy, switching to renewable energy sources is essential. Wind energy is one of the most popular renewable energy sources for generating electricity. Vertical-axis wind turbines (VAWTs) are used in urban areas due to their advantages, with cross-flow wind turbines (CFWTs) being one type. However, the efficiency of CFWTs is relatively low, necessitating the application of augmentation devices. This study aims to find the optimal configuration between CFWTs and Omni-Directional Guide Vanes (ODGV), using 6DOF dynamic mesh methods in ANSYS Fluent with varying the turbine blade counts and the addition of ODGV. The results showed that the 18-blade configuration exhibits the highest improvement with ODGV, demonstrating a remarkable 71 percent increase in the power coefficient. In general, the highest performance is achieved by the 20-blade turbine with a 6-blade ODGV configuration, with a power coefficient of 0.2455, which is 30 percent higher than the baseline 20-blade turbine. These findings indicate that the addition of ODGV significantly improves the performance of cross-flow wind turbines.

Abstract

More than a year has passed since Francisco Pérez-Arribas (2023) introduced a parametric-based hull design method using Python scripts, beginning with the cross-sectional area (CSA) design. Several experimental studies have been carried out to improve the method and the quality of ship design. This study aims to generate an optimal hull design by utilizing normal vectors derived from the x and y vectors. These normal vectors are applied parametrically to determine the shape of the hull. The study also employs a cubic spline-based parametric technique for designing yacht hulls. The purpose of this study is to introduce the concept of parametric design through the development of visual programming used to form cross-sectional area curves and generate hull geometry. This study also discusses both the advantages and limitations of using visual programming approaches to accelerate the design process. By varying the CSA shape of the DelftShip model, the resulting parametric model has a high level of accuracy, with a difference of - 0.097016% in LCB and -0.28785% in volume when compared to the DelftShip model. results from Grasshopper reveal significant differences, particularly below a draft of 0.475, where the CP values from Grasshopper are lower than those from DelftShip. The parametric approach using normal vectors not only facilitates design exploration but also holds the potential to enhance overall hull design quality and optimization.

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

On the 2919 GT Ro-Ro vessel, structural geometry changes, specifically in the Length Between Perpendiculars (LPP) with additional framing, lead to variations in loading and maximum stress, in accordance with Biro Klasifikasi Indonesia (BKI) regulations in Volume II. Finite Element Method analysis reveals structural responses, particularly in the parallel middle body section. Initially, the vessel was 10.5 meters long to support loads of seven 20-foot trucks; modifications increased this to 13.5 meters for loads of seven 40-foot trucks and 18 meters for a combination of 20-foot and 40-foot truck loads. The analysis results indicate significant differences in the vessel’s maximum structural stress under truck-loaded conditions. For lengths of 10.5 meters, 13.5 meters, and 18 meters, the stresses remain within safe limits under all conditions (Calm Water, Sagging, and Hogging), with σult lower than the allowable as set by BKI. However, the 18-meter length exhibits maximum stress approaching the safe threshold in the Hogging condition, with σult = reaching 243.4 MPa, suggesting structural modifications are required to ensure vessel safety.

Abstract

This study investigates the effects of extending the hull length of the KL Barombong training vessel, specifically on speed resistance, engine power requirements, propeller efficiency, and fuel consumption. The objective is to assess how these modifications impact overall vessel performance, particularly fuel efficiency and operational costs. Using Maxsurf simulation software, we analyzed the vessel's performance before and after the modification. Results show that extending the hull increased hydrodynamic resistance, requiring more engine power and raising fuel consumption by 12-15%. Additionally, the propeller efficiency declined due to the higher load. These findings emphasize the need for engine-propeller optimization during vessel modifications to ensure operational efficiency and sustainability. Recommendations for future modifications and system upgrades are also provided.

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

Central Tapanuli Regency is a region that has significant potential in the fisheries sector, mainly traditional fisheries, due to its extensive mangrove ecosystem and lengthy coastline. Mangroves are essential for the livelihood of local fishing, as they protect the marine environment and serve as a barrier against coastal erosion. The mangrove ecosystem in Central Tapanuli Regency is experiencing increased pressure due to land conversion, illicit logging, and other human activities, as research surveys indicate. This pressure has a negative impact on the productivity of catches and the welfare of fishermen. This risk is undoubtedly a significant concern; the ecological value of the mangrove ecosystem may be diminished, resulting in a decrease in the catch of local trap fishermen. Consequently, this research is necessary for the local government to reference when developing mangrove management strategies. This investigation aimed to assess the state of the mangrove ecosystem in Tapian Nauli Bay and the correlation between mangrove conditions and the socio-economic status of crab trawl fishermen. The investigation was conducted in Central Tapanuli, specifically in Tapian Nauli Bay. Surveys and interviews with respondents were implemented to accumulate data. Descriptive and correlational analyses are implemented. The results of this study indicated that 60% of the mangroves in Tapian Nauli Bay were in excellent condition, while only 30-40% were in poor condition. The income of bubu fishermen is significantly influenced by the presence of mangroves, as the catches they capture increase, thereby improving their livelihoods.

Abstract

Shipping safety is a main priority in all industries, including the shipping industry. The shipping industry must provide guarantee of the safety of people and cargoes in the shipping process. Ensuring shipping safety will support increased world trade. The development of the shipping industry has increased due to world trade, but this increase is not consistent with shipping safety standards. Shipping safety is low due to the quantity of ship accidents that have caused fatality and property loss. Humans error are one of the factors causing ship accidents. Inadequate skill and competence of ship crew is one of the indicators in human error that can cause ship accidents. Inadequate skill and competence of ship crew due to limited time and space to learn and improve their skills and competency. Purpose of this study is to develop maritime learning application prototype, that can be used crews to learn by ship and improve their competence and skills with flexible time and place. The name is application is Smart Shipping. The method used in this research is the waterfall method. The result of this research is an e-learning Prototype that was designed based on user’s competence and subject expertise as well as the position on the ship. Material in this e-learning can be downloaded for offline learning. Furthermore, e-learning provides learning evaluation to measure user understanding through questions, exercises, and tests. The shipping industry can use this e-learning as a preventive action of ship accidents due to human error.
