Abstract

Material selection in the construction industry is a strategic decision that affects the cost efficiency, durability, and sustainability of a project. This study applies the Analytic Hierarchy Process (AHP) method to determine the best construction material based on four main criteria: mechanical strength, environmental resistance, cost efficiency, and environmental sustainability. The hierarchical structure is built with three levels: material selection objectives, evaluation criteria, and compared material alternatives—namely structural steel, cross-laminated timber (CLT), and reinforced concrete. The assessment uses the Saaty scale (1–9), then the matrix is normalized to obtain priority weights. Consistency tests are carried out by calculating the maximum eigenvalue (λmax), Consistency Index (CI), and Consistency Ratio (CR). The results show that structural steel has the highest weight (0.4888093), making it the best choice compared to CLT and reinforced concrete. This study confirms that the AHP method is able to reduce subjectivity in decision making with a data-driven approach. Integration with technologies such as Building Information Modeling (BIM) and Artificial Intelligence (AI) can improve the accuracy of the analysis. Thus, this method can be a solution in selecting construction materials that are more systematic and sustainable.

Abstract

The development of transportation infrastructure has a multidimensional impact in driving economic growth and regional integration. The Jakarta-Bandung High-Speed Rail project is expected to reduce traffic congestion and improve connectivity and mobility efficiency. However, its success must be assessed not only from the technical aspects and physical completion, but also the effectiveness of public investment, long-term economic impacts, and environmental sustainability. The main challenges of this project include land acquisition, financial uncertainty due to debt-based financing schemes, and integration with other transportation systems. From a social perspective, this project has the potential to drive urbanization around the route, but also poses the risk of development inequality and gentrification. Ecological impacts are also a concern, especially in terms of land degradation and operational energy consumption. This study uses a literature study method with content analysis to evaluate the success of the project based on economic, social, and environmental indicators. The results of the study show that the effectiveness of this project is highly dependent on operational optimization, integration of transportation modes, and the sustainability policies implemented. With transparent governance and appropriate risk mitigation strategies, this project has the potential to provide long-term benefits for economic growth and community welfare, as well as being a model for more inclusive and sustainable transportation infrastructure development in Indonesia.

Abstract

In modern industries that increasingly rely on machines and automation systems, efficient maintenance is key to maintaining production continuity and avoiding losses due to unscheduled downtime. Preventive maintenance has emerged as a more effective solution compared to the corrective maintenance approach, which is reactive. This study discusses the urgency of implementing preventive maintenance in improving machine reliability, extending equipment life, and reducing long-term costs. The use of advanced technologies such as the Internet of Things (IoT), Computerized Maintenance Management Systems (CMMS), and predictive analytics can optimize preventive maintenance by detecting potential failures early, thereby minimizing downtime by up to 50%. However, the effectiveness of this strategy is highly dependent on the readiness of the digital infrastructure and the competence of the human resources (HR) who manage the technology. Without the integration of historical data, real-time monitoring systems, and adequate training, the implementation of preventive maintenance is at risk of being less than optimal. Therefore, the development of a technology-based preventive maintenance strategy must be accompanied by increased technical and managerial capacity, as well as organizational readiness to adapt to digital change. This research shows that a structured, data-driven preventive approach can support operational efficiency, strengthen competitiveness, and support industry sustainability.

Abstract

The Industrial Revolution 5.0 marks a paradigm shift from full automation to symbiotic collaboration between humans and machines, emphasizing a human-centric approach, sustainability, and the integration of intelligent technologies. In this context, the role of mechanical engineering has undergone a significant transformation, from merely designing mechanical systems to becoming a multidisciplinary bridge between digital technology and human needs. This study aims to review the literature related to the contribution of mechanical engineering in supporting intelligent manufacturing systems, human-machine collaboration, and the application of sustainability principles such as circular economy and eco-design. Using a qualitative literature study method, data were obtained from indexed academic sources in the last decade and analyzed using a thematic approach. The results of the study indicate that mechanical engineering must integrate artificial intelligence, the Internet of Things (IoT), and cyber-physical systems to support adaptive and efficient production. In addition, the development of cobots requires expertise in safety-based and ergonomic design. In terms of the environment, mechanical engineers are required to apply the principles of product life cycle engineering and low-emission technologies. This transformation creates cross-field challenges that require new competencies and a systemic approach. Therefore, a comprehensive literature review is a strategic basis for formulating the direction of adaptive and sustainable mechanical engineering development in the Industry 5.0 era.

Abstract

This study aims to examine the potential contribution of the Hybrid Renewable Energy System in supporting sustainable energy transitions in the future, especially in the context of reducing carbon emissions and dependence on fossil fuels. This study uses a descriptive-quantitative research type with an engineering simulation approach. The study focuses on modeling and analyzing the contribution of a hybrid renewable energy system (HRES) in reducing carbon emissions and reducing dependence on fossil fuels. . Based on the results of observations and analysis of technical data on solar radiation and daily wind speed, photovoltaic (PV)-based renewable energy systems show significant technical potential in generating electricity consistently throughout the year, especially in tropical areas. Meanwhile, although the potential for wind energy is relatively smaller, especially in areas with low average wind speeds, wind turbines can still provide additional contributions — especially when solar conditions are limited such as at night or in the rainy season. By combining these two energy sources into a hybrid system (HRES), the efficiency of renewable energy utilization can be maximized. The combination of PV and wind turbines allows : 1 ) Direct carbon emission reduction, which is ~22.7 tons of CO₂ per year from the PV system alone. 2) Diversification of energy sources, which reduces vulnerability to single dependence on fossil fuels. 3) Increasing the reliability of the electricity system, especially for remote areas and areas not yet covered by the PLN network. Overall, HRES provides a practical, efficient, and sustainable solution to meet the energy needs of small to medium-scale communities. It also opens up opportunities for energy decentralization, promotes a green economy, and strengthens Indonesia's commitment to net zero emissions targets in the future.

Abstract

The increasing demand for electricity in urban areas of Indonesia demands diversification of sustainable energy sources. On-grid Solar Power Plants (PLTS) are a strategic alternative to reduce dependence on fossil fuels and increase household energy resilience. However, optimizing PLTS design still faces technical and structural challenges, such as the mismatch between panel production capacity and electricity consumption patterns, limited space, and weak regulatory support and fiscal incentives. This study uses a qualitative approach with a case study in an urban housing complex to examine the design process, implementation, and obstacles of on-grid PLTS. Data were obtained through in-depth interviews, field observations, and studies of policy and technical documents. The results of the study indicate that the success of PLTS implementation is highly dependent on a design that is contextual to the technical and social characteristics of housing, the support of fiscal policies such as initial subsidies, and institutional integration between communities, local governments, and the private sector. In addition, community-based approaches such as energy cooperatives can increase inclusive system adoption. This study concludes that on-grid PLTS is not only a technical solution for the clean energy transition, but also an instrument of socio-economic transformation that requires multidimensional synergy in its implementation in the urban environment of Indonesia

Abstract

This study discusses the paradigm shift in mechanical engineering due to the adoption of 3D printing technology as part of the industrial revolution 4.0. This additive manufacturing technology offers advantages in terms of design complexity, production efficiency, and cost flexibility, but also raises technical challenges such as material anisotropy, surface roughness, and process parameter control. Through a descriptive qualitative approach based on literature studies, this study explores the impact of 3D printing on the structure of the manufacturing industry, performance-based design, and the need for reform in engineering education. Data sources are taken from scientific journals, academic books, and technical reports from the last decade (2014–2024), with a thematic analysis of technology applications, implementation challenges, and implications for mechanical engineering curricula. The results show that although 3D printing has fundamentally changed the design and production process, its integration into the industry is still limited by conventional supply chain structures and lack of human resource readiness. This study emphasizes the importance of transforming the engineering education system towards a digital-based interdisciplinary approach, as well as the need for critical and contextual technology adoption. Thus, 3D printing does not only act as a production tool, but also as a catalyst for systemic change in mechanical engineering and manufacturing.

Abstract

This study aims to examine the information system strategy in supporting the alignment between business needs and technology utilization through the Business Process Reengineering (BPR) approach. In a dynamic business environment, understanding external opportunities and threats, as well as the organization's internal capabilities, is an important foundation in designing information systems that can drive efficiency, effectiveness, and competitive advantage. Information systems not only play a role as operational support, but also as a driver of strategic transformation through innovation in processes, structures, and organizational culture. This study uses a qualitative descriptive method with a case study approach, involving in-depth interviews, observations, and documentation studies. The analysis techniques used include Critical Success Factors (CSF), Balanced Scorecard (BSC), and gap analysis to map actual conditions and determine future strategies. The results of the study are expected to produce an application portfolio that is in accordance with the needs of the organization, as well as a BPR strategy that is oriented towards improving service quality, reducing costs, and customer satisfaction. The strategic value of information systems is largely determined by the extent to which business understanding is integrated into the design of an adaptive system. Active participation at all levels of the organization, including through workshops based on actual data, is key to formulating effective and sustainable strategies.

Abstract

Amidst increasingly tight business competition and increasingly critical customers in choosing products or services, companies are required to build more personal and sustainable relationships through Customer Relationship Management (CRM) strategies. The IDIC (Identify, Differentiate, Interact, Customize) model developed by Peppers and Rogers is one of the effective approaches in implementing CRM in a structured and strategic manner. This study aims to analyze the application of the IDIC Model in improving the effectiveness of customer relationship management. The approach used is qualitative with descriptive-analytical methods, through literature studies and literature analysis from various relevant sources. The results of the discussion show that the IDIC Model facilitates companies to recognize customers comprehensively, differentiate them based on value and needs, build meaningful interactions, and customize offers individually. Identify and Interact are included in the operational CRM realm, while Differentiate and Customize are part of analytical CRM that relies on customer data analysis. This model enables large-scale personalization, which is strengthened by big data technology and artificial intelligence (AI), so that companies can increase customer engagement, loyalty, and business profits sustainably. The application of the IDIC Model reflects a shift from mass marketing to a more relevant one-to-one marketing approach in the digital era
