This research focuses on Sanur Harbor, an inter-island ferry port located in southern Bali. The majority of visitors to Sanur Harbor are tourists who want to travel to Nusa Penida Island. At this port, facilities are available in the form of a Public Address System (PAS) and Information officers whose job is to provide information regarding the arrival and departure of ships. However, the effectiveness of this facility is limited for deaf people. Deaf people often have difficulty getting this information independently and often have to rely on manual assistance from officers. This research aims to develop software based on sign language video integration which aims to increase the accessibility of departure and arrival information at Sanur Harbor for deaf people in Bali. The software development method uses a user-centered design development approach which involves the stages of needs analysis, design, implementation, and evaluation. Sign language videos will be integrated into the software as a medium to convey important information about ship departure and arrival schedules, travel routes, pier names, fast boat names, and other important information to deaf users. Evaluation is carried out through user testing and collecting feedback from users regarding understandability, usability, and user satisfaction with the software being developed. It is hoped that the results of this research can make a positive contribution to increasing information accessibility for deaf people in Sanur Harbor and can become a basis for developing similar technology in other locations. © 2024 IEEE.

The influence of carbon dioxide (CO2) curing on the compressive strength of oil shale ash (OSA) concrete as partial cement replacement was investigated. 15 cm cubes with a 30% replacement percentage were tested after seven days of conventional curing and carbonation curing at 4 bar CO2 pressure. Research results demonstrate that CO2 curing influences the compressive strength of concrete significantly. There is a linear relationship between CO2 pressure and the duration of curing, as well as the compressive strength of OSA-based concrete. A sample of ordinary Portland cement was used as the control sample. The replacement of 30% cement by OSA increased the 7-day compressive strength from 48.5 to 55.5 MPa for plain cement samples and from 36.5 to 42.3 MPa for ash-based samples. From a technical standpoint, OSA-based concrete carbonation curing is still too immature for widespread application. Nonetheless, it is continuously developing in response to greenhouse gas reduction and paving the path for a more sustainable construction materials business. © 2024, Institute of Technology PETRONAS Sdn Bhd.

Trends in citizen influencing willingness to participate in marine debris management and social well-being in Bali metropolitan, Indonesia

Urban Governance 2024年第4期4卷 362-373页

In Bali, the high volume of tourists significantly contributes to marine debris, particularly plastics, which threatens the ecological health of beaches and marine life, impacting both tourism and local livelihoods. Effective management is crucial to preserve Bali's natural beauty and sustainability. This study explores the factors influencing the willingness to participate (WTP) in marine debris management among urban communities in the Bali metropolitan area, Indonesia. Utilizing a binary logistic regression model, we examine the impact of key elements for effective marine debris management, risk awareness, learning performance, and higher monthly income and geographic differences between inland and coastal communities. The findings reveal that effective management practices significantly enhance community participation, highlighting the importance of transparency, accountability, and well-organized efforts. Educational initiatives also play a crucial role, with performance in risk awareness and learning showing a marginally significant positive effect on WTP. Conversely, higher income levels negatively influence participation, suggesting a preference for institutional funding over personal contributions. Geographic differences indicate that coastal communities are more inclined to participate than inland communities. These insights provide valuable guidance for policymakers and practitioners in developing strategies to mobilize volunteers, enhance urban resilience, and promote social well-being. By implementing effective management practices, comprehensive educational programs, tailored engagement strategies, and fostering partnerships, urban communities in Bali can become more resilient and actively address environmental challenges. © 2024 The Authors

This study examined the effect of Zn2+ ion substitution on ZnxMn(1-x) Fe2O4 nanoparticles (x = 0.2, 0.4, 0.6, 0.8) towards signal Surface Plasmon Resonance (SPR). The co-precipitation method synthesised the nanoparticles at a temperature of 90°C. The X-Ray Diffraction (XRD) results showed a polycrystalline structure with a crystallite size varied from 19.05 nm to 19.77 nm. In addition, as the Zn element increased in the ZnxMn(1-x)Fe2O4 nanoparticles, the degree of crystallinity increased by 21.72%, respectively. The optical properties of the nanoparticles ZnxMn(1-x) Fe2O4 indicate absorbance at wavelengths of 330.36–331.74 nm. The absorbance level increased as the Zn element decreased, resulting a direct optical gap of 3.47 eV and an indirect optical gap of 3.23 eV. The Attenuated Total Reflection (ATR) curve in the SPR biosensor indicated a shift in the reflective angle of the Prism/Au/Air configuration, which is 47.78° on Prisma/Au/nanoparticle of Zn0.8Mn0.2Fe2O4/air by 50.75°, and the prism/Au/nanoparticle of Zn0.2Mn0.8Fe2 O4/air by 51.04°. The substitution of Zn ions in the compound Zn x Mn(1-x)Fe2O4 affects the resulting ATR curve. The shift in the SPR angle is caused by changes in the refractive index in each layer which is influenced by the concentration of each material which has an impact on the absorbance ability and photon reflectance. This research has the potential to continue with the testing of dielectric and magnetic properties, as well as special testing for biological analytes compatible with ZnxMn(1-x)Fe2O4 nanoparticles. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

As a form of sportification of Human-Computer Interaction (HCI), eSport are revolutionizing the video game and sports industry in the digital transformation era. Applying Self-Determination Theory (SDT), this study aims to try to understand the relationship between the motivations that make people 'eSport fans' with their behavior in supporting eSport so that it has an impact on the level of individual innovative behavior. Using Partial Least Squares -Structural Equation Modeling (PLS-SEM) as a data analysis approach with the Smart PLS 3 tool was carried out in this study. A survey was conducted among 100 people to investigate their behavior related to eSport at the level of individual innovative behavior. The findings indicate that eSport as intrinsic motivation has a larger role in idea exploration, idea generation, and idea championing than in idea implementation. This contributes to applying SDT in the context of eSport and innovative behavior. © 2023 IEEE.

Geothermal reservoirs are significant sources of renewable energy. Accurate geometric modeling of these reservoirs is essential for understanding the distribution of heat and fluid dynamics within them. This study aims to develop a geometric model of the Sibayak geothermal field using borehole data. Borehole data provide detailed geological information, which is crucial for constructing a realistic geometric model. The methodology of this research involves several key steps: the collection of borehole data from the Sibayak geothermal field, the construction of a 3D geometric model of the reservoir using COMSOL Multiphysics based on the borehole data, and the validation of the model through comparison with field data and previous research findings. The results indicate that the developed geometric model successfully identifies zones with high geothermal potential and provides an accurate depiction of the reservoir's boundaries and characteristics. Modeling the geometry of geothermal reservoirs using borehole data offers profound insights into the internal dynamics of the reservoir and can serve as a valuable tool for planning and optimizing geothermal energy exploitation. © 2024 Institute of Physics Publishing.
