pISSN : 3031-3279 and eISSN: 3031-6723 In the era of the industrial revolution 4.0, more and more engineers are needed in various fields. In the future, all human work will be run over by machines. Therefore, the role of engineers is required in the current era of the industrial revolution 4.0. Infrastructure is a physical or non-physical facility that supports the smooth running of community activities. Not all infrastructure can support the smooth running of community activities. For example, infrastructure that is built but cannot function properly. Infrastructure created and needs to be fixed can even hinder the smooth running of community activities. Infrastructure that cannot function properly can be caused by poor design plans or caused by poor construction practices. Design plans and construction implementation generally involve experts, and the engineering profession can also be interested. With this involvement, an engineer also has roles and responsibilities in creating an infrastructure that can function properly. Therefore, innovation and synergies are needed to produce engineering research by universities, research institutions, and industries that can contribute to this problem. In addition, the Collaborate Engineering Daily Book Series aims to answer whether research on engineering innovation by universities, research institutes, and industry can contribute to the issue of World Engineering. This contribution is expected to exchange information, experiences, and thoughts and strengthen the cooperation network between institutions, institutions, and industries on a national/international scale. So that scientific communication is established between researchers, industry, and education.

Inter-Island Submarine Pipelines for Clean Water in Indonesia
The provision of clean water in Indonesia’s archipelagic regions remains a significant challenge, particularly for small islands lacking adequate freshwater resources. Lae-Lae Island in Makassar represents a critical case, where all groundwater sources have been classified as lightly polluted due to seawater intrusion and domestic activities, while the water supply deficit reaches approximately 95,000 liters per day. This study aims to analyze clean water distribution issues from two main perspectives: technical aspects and basic service provision. The method employed is a literature review combined with comparative analysis of several submarine pipeline installations in Indonesia. The results indicate that the use of High-Density Polyethylene (HDPE) submarine pipelines is a technically feasible solution to distribute clean water from mainland Makassar to Lae-Lae Island, considering the relatively short distance and the availability of an existing municipal water supply network. Furthermore, successful implementations in other regions demonstrate that this technology is reliable and applicable. However, the primary challenges lie in policy and institutional frameworks, where inter-island pipeline systems have not yet been positioned as integrated basic service infrastructure. Therefore, an integrated approach combining engineering planning and public policy is required to ensure sustainable clean water services. Lae-Lae Island is considered a strategic starting point for implementation, with the potential to be replicated across other small islands in Indonesia.

The Role of Pipeline Route Selection in Clean Water Distribution to Address Drought in Kupang Regency
Drought remains a significant challenge in meeting the clean water needs of communities in Kupang Regency. The construction of Raknamo Dam is expected to serve as a primary water source; however, the effectiveness of water distribution largely depends on proper pipeline network planning, particularly in selecting an appropriate route. This study aims to analyze the influence of pipeline route selection on the performance of clean water distribution systems. A descriptive-comparative approach was employed by evaluating three alternative routes based on pipeline length, elevation differences, and potential flow energy losses (head loss). The results indicate that the shortest route does not necessarily provide the best performance, as significant elevation changes can increase energy losses and reduce flow stability. In contrast, routes that follow the natural terrain contours tend to produce more stable and efficient water distribution. Therefore, pipeline route selection that considers topographical conditions and hydraulic aspects plays a crucial role in supporting effective clean water distribution systems in drought-prone areas.
Undersea Pipeline Installation Perspective
The availability of clean water is a basic need that is crucial in supporting human life and the development of tourism areas. Bokori Island, as a leading tourist destination, faces limited natural clean water sources, so that the water needs of tourists are not optimally met. This perspective article aims to evaluate the clean water distribution system through an underwater pipeline network from Kendari City to Bokori Island, with a primary focus on mapping maritime challenges in Indonesian waters. The method used is a qualitative analysis of marine environmental conditions, human activities, and operational aspects. The identification results show that although the shallow water route facilitates installation, there are significant risks from human activities such as ship traffic, as well as oceanographic dynamics such as ocean currents and corrosion levels. In conclusion, the underwater pipeline distribution system is a feasible solution, but its success is highly dependent on mitigating external technical risks and selecting appropriate protective materials. This abstract emphasizes the importance of a comprehensive approach without complex mathematical modeling in coastal infrastructure planning.
The Paradigm of Installation-Oriented Planning
The selection of a pipeline route is a critical stage in submarine installation projects that dictates technical success and longterm cost efficiency. This article evaluates the corridor planning for a clean water transmission system from the Leupung mountain springs to the Banda Aceh distribution center, specifically comparing conventional land alignments with submarine alternatives. The study employs a comparative evaluation based on techno-economic criteria, including seabed geology, bathymetry, and natural disaster mitigation specifically addressing the landslide risks prevalent in the Aceh Besar region. The analysis emphasizes that route selection is an "installation-oriented planning" process rather than a mere geometric exercise. By integrating hydrodynamic stability factors and shore approach methods, the research argues that a submarine route utilizing High-Density Polyethylene (HDPE) provides superior resilience against the seismic and geological characteristics of Aceh.
Optimizing Route Selection for Inter-Island CPO Pipeline
Route selection is the most critical stage in pipeline system planning, particularly for cross-border subsea installations. This study examines the optimization of a crude palm oil (CPO) pipeline route from Riau to Selangor via the Strait of Malacca using a corridor-based route planning approach. The methodology includes a comparative analysis of several alternative alignments and a multi-criteria evaluation covering technical, economic, environmental, and operational aspects. The study also references global pipeline projects such as the Trans-Alaska Pipeline System and the Druzhba Pipeline as benchmarks. The results indicate that the shortest route is not always optimal, and that a corridor-based approach can produce routes with lower risk and better long-term cost efficiency.
Route Selection Analysis of Inter-Island Clean Water Pipeline to Address Water Crisis in Sumba Island
The clean water crisis is one of the major challenges in dry island regions such as Pulau Sumba. Limited water resources, low rainfall, and uneven distribution have led to increasing demand for clean water. One proposed solution is the distribution of water from regions with better availability, such as Pulau Sumbawa, through a subsea pipeline system. This study aims to analyze the conceptual feasibility of inter-island clean water pipeline route selection by considering technical, environmental, and risk factors. The results indicate that route selection is a critical factor not only determined by distance but also by bathymetric conditions, seabed morphology, ocean currents, and geological risks. In addition, the project faces significant challenges in terms of cost and operation. Therefore, a comprehensive planning approach is required to ensure the technical feasibility and sustainability of inter-island clean water distribution systems.
Planning the Clean Water Pipeline Route from Makassar to Kodingareng Lompo Island
Kodingareng Lompo Island is a small island in the Makassar coastal region that faces persistent clean water shortages due to seawater intrusion, limited freshwater resources, and increasing water demand. One potential solution is the distribution of clean water from mainland Makassar through a subsea pipeline system. In such projects, route selection is a critical planning stage that significantly influences installation feasibility, operational reliability, and long-term project sustainability. This article examines the role of route selection in subsea pipeline planning using a literature-based perspective approach. The discussion focuses on the limitations of conventional shortest-path methods and highlights the importance of considering bathymetric conditions, maritime activities, environmental factors, and installation constraints. The study argues that corridor-based planning and multi-alternative route evaluation provide a more comprehensive framework for decision-making than distance-based optimization alone. Furthermore, route selection should be integrated with installation planning to minimize technical risks and improve system reliability. The findings emphasize that successful clean water distribution to Kodingareng Lompo Island depends not only on hydraulic design but also on the selection of a route that balances technical, operational, environmental, and economic considerations.
Environmental Considerations in Subsea Clean Water Pipeline Installation from Manado to Bunaken Island to Support Resort Sustainability
Clean water availability is one of the main factors in supporting the sustainability of small island tourism areas, especially in regions with limited freshwater resources. Pulau Bunaken, as a marine tourism destination, has an increasing demand for clean water due to the growth of resorts, homestays, and tourism activities. One potential solution is the construction of a subsea clean water pipeline from Manado to Bunaken Island. However, the planning of such a system must consider coastal and marine environmental sensitivity, particularly coral reefs, seagrass beds, and marine habitats. This article aims to analyze the importance of environmental aspects in subsea pipeline route selection through a literature review and conceptual analysis approach. The discussion indicates that the shortest route is not always the best route if it passes through ecologically sensitive areas. Route avoidance, spatial mapping, and the integration of environmental data should be applied from the early planning stage. Therefore, clean water infrastructure development can proceed in parallel with marine environmental conservation.
Engineering Strategies in Dealing with Environmental Constraints in Pipeline Installations in Sensitive Coastal Areas
Undersea pipeline route planning in coastal areas requires an approach that integrates engineering and environmental aspects simultaneously from the early stages of design. Based on a literature review of the "Guidelines for Marine and Coastal Environmental Impact Assessment" by the International Finance Corporation as well as scientific publications such as "GIS-Based Multi-Criteria Analysis for Pipeline Route Selection" by Springer and various studies in the journal Ocean Engineering (Elsevier), it is known that environmental constraint is an important parameter in engineering planning. The concept of coastal sensitivity which includes mangrove areas, estuaries, and coral reefs is integrated into the route selection process through a GIS-based approach and multi-criteria decision analysis. The results of the study show that route avoidance strategies for sensitive areas not only significantly reduce ecological impacts, but also improve technical efficiency by minimizing risks such as seabed soil instability, disturbances during installation, and potential additional costs due to advanced mitigation. In addition, international guidelines affirm that avoidance is a priority step before mitigation in the hierarchy of environmental impact management. Thus, route avoidance can be positioned as an integral part of the engineering strategy in undersea pipeline planning, not just a response to environmental regulations, but rather as a design approach that supports the sustainability and reliability of infrastructure in sensitive coastal areas.
Why Subsea Pipeline Installation Is Not Merely a Construction Issue
Subsea pipeline installation is a critical component of offshore energy infrastructure that has traditionally been understood as a technical construction activity on the seabed. However, developments in the literature indicate that the success of this system is not solely determined by the installation phase, but is highly dependent on early planning processes, particularly pipeline route selection and seabed condition assessment. This article aims to conceptually examine that subsea pipeline installation is a multidimensional process involving technical, spatial, and risk-based aspects. The study is conducted using a literature review approach, referring to studies on Pemping Island as well as subsea pipeline engineering literature. The results show that seabed conditions such as slope, sediment type, and geohazard zones have a significant influence on pipeline route stability. Therefore, subsea pipeline installation should be understood as part of a risk-based decision-making system, rather than merely a construction activity.
The Environmental-Driven Route Selection Paradigm
Route selection for subsea pipelines in Indonesia has traditionally been dominated by distance efficiency parameters in order to minimize capital expenditures. However, this approach tends to overlook the complexity of Indonesia’s dynamic and sensitive marine ecosystems. This perspective article argues that Environmental and Coastal Sensitivity must be repositioned as a primary engineering constraint, rather than merely a regulatory barrier or a post-design obligation. Drawing on the theoretical foundations of coastal hydrodynamics and infrastructure risk management, the author critically analyzes the shortcomings of the “shortest route” approach, which often triggers technical risks such as premature corrosion, scouring, and free-spanning phenomena in coral reef and estuarine areas. The author proposes a Route Avoidance strategy as a superior engineering solution compared to conventional environmental compensation strategies. The analysis results show that integrating environmental sensitivity weights into a multi-criteria decisionmaking model not only protects biodiversity but also enhances the pipeline structure’s resilience to coastal morphological changes in Indonesian waters. This article concludes that a paradigm shift toward the “ecologically most stable route” is imperative to ensure long-term operational integrity and operational expense (OPEX) efficiency.
Relationship of Pipeline Route to Long Term Integrity
The provision of clean water to island regions such as Gusung Island by the Makassar Regional Water Company (PDAM Makassar) requires a complex and high risk seaborne pipeline system. This article examines Scope 8 as the comprehensive management of pipeline assets, encompassing planning, construction, operation, maintenance, and continuous evaluation of system performance. The aim is to identify key risks and analyze factors affecting pipeline integrity. The study results indicate that key risks include corrosion due to the marine environment, headloss, mechanical damage due to waves, currents, and shipping activities, as well as potential leaks due to material fatigue and joint failure, which are also influenced by seabed geotechnical conditions and environmental changes. Pipe integrity is largely determined by the selection of appropriate materials such as HDPE or coated steel, the implementation of protection systems such as coatings and cathodic protection, and the implementation of risk based inspections and regular condition monitoring. With the implementation of integrated and data driven risk management, the seaborne pipeline system can operate more safely, efficiently, and sustainably, thereby supporting the sustainability of clean water distribution in island regions.
Social Conflict and Environmental Challenges in Non-Conventional Energy Projects
The development of non-conventional energy is one of the main strategies in dealing with the global energy crisis and climate change. Energies such as solar, wind, biomass, and marine energy are promoted as more environmentally friendly alternatives to fossil energy. However, behind this positive image, there are various social conflicts and environmental challenges that are often overlooked in the implementation process. This perspective article aims to critically examine the dynamics of social conflict and environmental impacts that arise from the construction of non-conventional energy projects. The method used is a qualitative approach through literature study and conceptual analysis. The results of the discussion show that social conflicts are generally related to land issues, community participation, and inequality in the distribution of economic benefits. Meanwhile, from the environmental side, non-conventional energy development can trigger ecosystem disturbances, changes in land use, and uncertainty of long-term impacts. Therefore, a more inclusive, ecosystem-based, and social justice-oriented approach to development is needed so that the energy transition can run sustainably.
Economic, Social, and Environmental Aspects of Ocean Current Turbine Installations in the Indonesian Strait
The development of tidal current power plants in Indonesia's straits not only considers technical aspects but also carries significant implications from economic, social, and environmental perspectives. From an economic standpoint, the initial investment for installing tidal current turbines is relatively high, particularly regarding foundational construction, submarine cable installation, and supporting infrastructure. Nevertheless, the potential for stable and sustainable energy can yield long-term benefits by reducing dependence on fossil fuels and enhancing energy security across the archipelago. Furthermore, this project has the potential to stimulate local economic growth through job creation at the construction, operational, and maintenance stages. From a social perspective, the development of tidal current turbines must take into account interactions with coastal communities, particularly fishermen and shipping lane users. The presence of turbines may affect fishing activities and navigational access, necessitating inclusive and participatory marine spatial planning. On the other hand, the provision of reliable electricity can improve the quality of life for coastal communities, open opportunities for small industry development, and support equitable development in remote areas. Meanwhile, from an environmental standpoint, the installation of tidal current turbines has a relatively lower impact compared to fossil fuel-based power plants, yet still requires thorough assessment. Potential impacts include changes in local current patterns, disturbances to marine biota habitats, and risks to fish and marine mammal migration. Additionally, bio fouling and structural deterioration can disrupt operations and necessitate the use of environmentally friendly materials and technologies. Therefore, a comprehensive environmental impact analysis and appropriate mitigation strategies are essential to ensure that tidal current energy development proceeds sustainably and in harmony with the conservation of Indonesia's marine ecosystems.
Technical Aspects and Installation Challenges of Ocean Current Turbines in the Indonesian Strait
The straits of Indonesia possess unique hydrodynamic characteristics resulting from the interaction of tidal currents, the Indonesian Throughflow, and the influence of seasonal monsoons. These conditions make the straits a potential location for the development of turbine-based ocean current power plants. This study discusses the technical aspects and challenges of installing ocean current turbines in Indonesian straits by reviewing key parameters such as current velocity, water depth, seabed characteristics, turbulence, and wave and wind loads. The technical analysis covers the selection of turbine types (horizontal-axis and vertical-axis), foundation systems (monopile, gravity-based, or mooring systems), subsea power transmission systems, and integration into the onshore power grid. The main challenges identified include seasonal current variability, the potential for biofouling and corrosion due to the tropical marine environment, the complexity of installation in waters with strong currents, port infrastructure limitations, and navigation safety aspects in active shipping lanes. Additionally, environmental and social factors such as impacts on marine ecosystems and fishing activities are also important considerations in planning. The study’s findings indicate that, technically, the installation of ocean current turbines in the Indonesian straits is feasible, but requires an adaptive design approach, comprehensive oceanographic studies, and installation strategies that account for local conditions. With proper planning, this technology has the potential to become a reliable and sustainable source of renewable energy for Indonesia’s archipelago.
Development of Non-Conventional Energy Based on Ocean Wave Energy from an Economic, Social, and Environmental Perspective
The development of non-conventional energy is a key strategy in addressing the challenges of the global energy crisis, climate change, and the need for a sustainable energy system. One energy source with significant potential but not yet optimally utilized is ocean wave energy. Indonesia, as an archipelagic country with a long coastline, offers significant opportunities for developing this energy. This article comprehensively discusses the development of ocean wave energy as part of non-conventional energy, reviewing economic, social, and environmental aspects in an integrated manner. Economically, wave energy has the potential to become an alternative energy source that can reduce dependence on fossil fuels and open up new investment and job opportunities. Socially, this energy development can increase energy access in coastal areas and remote islands, while simultaneously encouraging local community empowerment. Environmentally, wave energy is relatively environmentally friendly due to its low carbon emissions, although it still requires proper management to minimize its impact on marine ecosystems. Using a descriptive-analytical approach, this article demonstrates that integrating economic, social, and environmental aspects is crucial to ensuring the success of wave energy development. Policy support, technological innovation, and collaboration among stakeholders are key factors in realizing a sustainable and inclusive energy system in the future.
The development of marine renewable energy is a strategic solution to support the global energy transition towards a low-carbon energy system. However, the utilization of single marine energy sources, such as wave energy, ocean currents, and offshore wind, still faces challenges in the form of intermittency and power fluctuations that can affect system reliability. This perspective article discusses the concept of a hybrid marine renewable energy system that integrates wave, current, and wind energy in a single integrated system with a focus on increasing reliability. The discussion focuses on the system integration architecture, reliability aspects, and the role of modern control and monitoring technologies. Based on a literature review and conceptual analysis, the hybrid system is considered capable of increasing capacity factors, reducing power fluctuations, and increasing system availability compared to single-source marine energy systems. The integration of multiple marine energy sources supported by energy storage systems and intelligent power management is seen as an important approach in realizing a reliable and sustainable marine energy system in the future.
The global energy paradigm shift from conventional to unconventional resources has ignited a profound debate on sustainability. This article explores the complexities of extracting unconventional energy such as shale gas, geothermal, and coal-bed methane within the framework of the three pillars of sustainable development: economic viability, social equity, and environmental integrity. Through a critical lens, it is argued that the rapid advancement of extraction technologies often outpaces regulatory frameworks and socio-ecological safeguards. This "fragile balance" is analyzed through the phenomena of negative externalities, agrarian conflicts, and market volatility. The article concludes that energy progress must be redefined not by production volume, but by systemic integrity and intergenerational justice.
Regulatory and Policy Barriers to Marine Renewable Energy in Indonesia
Indonesia possesses vast potential for marine renewable energy (MRE), including tidal, ocean current, and ocean thermal energy (OTEC). However, its utilization remains significantly below the national energy mix targets. This perspective article examines the gap between Indonesia’s energy transition ambitions and the existing regulatory realities. Through a critical review of current policies, we identify three major barriers: (1) overlapping authority among institutions, (2) the absence of a dedicated fiscal incentive framework for marine technologies, and (3) the lack of a comprehensive and integrated national roadmap within the National Energy General Plan (RUEN). We argue that without cross-sectoral regulatory alignment and legal certainty for investors, the potential of MRE will remain largely untapped. This article highlights the importance of establishing a “one-stop” policy framework and developing a technology roadmap that reflects Indonesia’s archipelagic characteristics. In conclusion, strengthening regulatory frameworks is not merely an administrative step, but a fundamental prerequisite for positioning marine energy as a pillar of Indonesia’s future energy sovereignty.
Marine Energy Installations and Coastal Ecosystems
The transition to renewable energy encourages the acceleration of the development of marine energy such as waves, currents, and tides. Despite being categorized as low-carbon energy, marine energy infrastructure installations raise critical questions regarding their impact on vulnerable coastal ecosystems. This perspective article aims to critically analyze the environmental aspects of marine energy installations and offer a mitigation approach based on the principles of prudence and adaptive management. The perspective raised emphasizes that the success of marine energy is not only determined by technological efficiency, but also by the integration of ecological considerations in project planning, design, and operation.
Offshore Platform Operational Risk Management in Extreme Weather Conditions
Offshore platform operations have a high level of risk due to direct exposure to dynamic marine environmental conditions, especially during extreme weather events such as storms, high waves, and strong winds. This research and study aims to explain the importance of the application of operational risk management in maintaining worker safety, equipment reliability, and production sustainability on offshore platforms. The risk management approach is carried out through the identification of potential hazards, risk level analysis, and the implementation of mitigation strategies which include improving structure design, real-time monitoring systems, and emergency response procedures. In addition, the use of weather prediction technology and sensor-based monitoring systems is an important part of supporting operational decision-making. With the implementation of effective risk management, it is hoped that potential losses due to operational failures can be minimized, while increasing the resilience of offshore infrastructure to the impacts of climate change and increasing the intensity of extreme weather. This study confirms that the integration of engineering, occupational safety, and operational management aspects is the main key in risk management in the offshore industry.
Marine Disaster Risk Management: The Contribution of Maritime Engineering
Marine disasters such as tsunamis, tropical storms, coastal flooding, and coastal abrasion are serious threats to coastal communities, maritime infrastructure, and economic activity. Marine disaster risk management is very important to minimize its negative impact. Marine engineering plays a strategic role in risk mitigation through the design of coastal protection structures, such as sea walls, breakwaters, and seawalls, as well as hydrodynamic modeling to predict the behavior of waves, currents, and tides in extreme conditions. In addition, marine engineering supports the development of sensor, radar, and satellite-based marine disaster warning and monitoring systems, enabling rapid and precise decision-making. With the integration of structural engineering, scientific modeling, and monitoring technology, marine disaster risk management becomes more comprehensive, proactive, and sustainable. This article discusses the contribution of marine engineering in minimizing the risk of marine disasters and improving the safety and resilience of coastal areas. With the integration of structural engineering, scientific modeling, monitoring technology, and community participation, marine disaster risk management becomes more comprehensive, proactive, and sustainable. This article discusses the contribution of marine engineering in minimizing the risk of marine disasters and improving the safety, resilience, and sustainability of coastal areas.
Field-Based Daily Journal: Studying Coastal Abrasion in Environmental Engineering
Coastal abrasion is an increasingly critical environmental issue affecting coastal ecosystems, infrastructure, and human settlements due to the combined impacts of climate change, sea-level rise, wave dynamics, and anthropogenic activities. This study presents a four-week field-based daily journal documenting coastal erosion processes in a vulnerable shoreline area through systematic observation of shoreline retreat, wave behavior, sediment characteristics, vegetation cover, and human activities. A mixed-method approach was employed, integrating quantitative measurements such as shoreline position, sediment grain size, and wave intensity with qualitative assessments including community behavior and coastal management practices. The results indicate that abrasion rates were highest in areas lacking natural vegetation buffers and in locations exposed to high-energy waves, while mangrove-covered zones exhibited significantly lower erosion. Human activities such as sand mining and coastal construction were identified as major contributing factors to shoreline instability. The study concludes that effective coastal management requires an integrated approach combining environmental engineering interventions, nature-based solutions, continuous monitoring, and community engagement to enhance coastal resilience and sustainability.
Daily Engineering Journal: Environmental Engineering Practices in Sustainable Waste Management
Sustainable waste management is one of the critical challenges facing modern urban and institutional environments, driven by rapid population growth, industrialization, and changing consumption patterns. Improper waste handling contributes to environmental pollution, greenhouse gas emissions, and ecosystem degradation, posing significant risks to human health and sustainability. This study documents the daily implementation of environmental engineering practices in municipal solid waste management, focusing on waste segregation, recycling, composting, and safe disposal methods. Daily observations were conducted over four weeks in an institutional setting, capturing operational workflows, behavioral participation, challenges, and outcomes. Quantitative analysis measured segregation efficiency, recycling rates, compost output, and landfill reduction, while qualitative observations focused on social engagement and operational effectiveness. Results indicate that consistent waste segregation, active community participation, and proper technical implementation significantly improve sustainable waste management outcomes, though contamination and behavioral inconsistencies remain challenges. The study demonstrates that integrating technical solutions with social engagement strategies is essential for achieving environmental sustainability and provides practical lessons for institutional and urban waste management programs.
As embedded systems become ubiquitous, their exposure to side-channel attacks exploiting physical leakages like power signatures in DPA and timing variations in branch prediction attacks demands innovative defenses. This study presents a detailed hardware-based approach integrated into system design, utilizing a co-design framework that combines secure modules such as electromagnetically shielded processors, randomized clocking mechanisms to introduce unpredictability, and software optimizations for embedded real-time systems. Employing a multidisciplinary methodology, we leveraged simulations in LTSpice for electrical modeling and collaborative prototyping on FPGA clusters, simulating attacks across diverse scenarios. Results indicate a 40% drop in attack success rates, with energy efficiency maintained through techniques like adaptive power gating, supported by empirical data on latency and power draw. The findings stress the importance of security in early design phases, with practical applications in IoT ecosystems and automotive infotainment systems. To foster broader adoption, we propose alignment with standards like NIST SP 800-57 for cryptographic modules. Future directions include interdisciplinary collaborations for AI-enhanced defenses and quantum-safe hardware, ensuring systems remain secure against sophisticated, adaptive threats.

Material Technology and Design Strategies for Future Structures
Advancements in material technology have fundamentally transformed structural design strategies, enabling the development of structures that are stronger, lighter, and more adaptable than those built with conventional materials. Innovative materials such as high performance concrete, fiber reinforced polymers, and smart alloys provide superior mechanical properties, including higher strength to weight ratios, enhanced durability, and improved resistance to environmental degradation such as corrosion, chemical attack, and temperature fluctuations. The integration of these materials allows for longer spans, slimmer structural elements, and more complex architectural designs while reducing maintenance requirements and extending service life. Comparative analyses and case studies demonstrate that advanced materials enhance structural efficiency, resilience under dynamic loads such as earthquakes, and sustainability by minimizing resource consumption and environmental impact. However, challenges remain, including higher initial costs, specialized construction techniques, and limited long term performance data in some applications. To optimize their use, hybrid material systems, large scale implementation, and the integration of digital modeling and structural health monitoring are recommended.

Accelerating Deep Learning on Edge Devices: Hardware-Software Co-Design for Efficient Neural Networks
The rapid growth of deep learning applications on edge devices has created significant challenges related to computational complexity, energy consumption, and latency. Unlike cloud-based systems, edge devices operate under strict resource constraints, including limited processing power, memory capacity, and energy availability. These limitations necessitate efficient strategies to enable real-time and reliable deep learning inference at the edge. As a result, hardware-software co-design has emerged as a promising approach to optimize neural network performance while maintaining energy efficiency and deployment feasibility. This paper investigates a hardware-software co-design framework for accelerating deep learning models on edge devices. The proposed approach jointly optimizes neural network architectures and underlying hardware platforms by integrating model compression techniques, such as quantization and pruning, with hardware-aware design strategies. Custom accelerators, parallel processing architectures, and memory-efficient dataflows are considered to minimize latency and power consumption while preserving inference accuracy. Experimental evaluations demonstrate that the co-designed system achieves significant improvements in inference speed and energy efficiency compared to conventional hardware-agnostic implementations. The results indicate reduced computational overhead and memory access costs, making the proposed framework suitable for real-time edge intelligence applications such as Internet of Things (IoT), autonomous systems, and mobile computing. Overall, this study highlights the importance of collaborative hardware-software optimization in addressing the performance and efficiency challenges of deploying deep learning models on edge devices. The findings provide practical insights for designing scalable and energy-efficient edge AI systems and contribute to the advancement of next-generation intelligent edge computing
