Abstract

This research aims to examine tsunami mitigation using a collaborative approach, particularly at the local level. The main focus is to understand how collaboration between various stakeholders can improve the effectiveness of tsunami mitigation in areas with tsunami potential. The theoretical framework of this research is based on the theories of collaboration and disaster management. Collaboration theory (ontology) explains the importance of cooperation between various parties, including government, communities and non-governmental organizations, in dealing with disasters. The epistemology of this research focuses on how knowledge about disaster mitigation can be acquired and applied through a collaborative approach. This research uses a qualitative method with a case study approach. Data was collected through in-depth interviews with stakeholders at the local level, including local government officials, community members, and representatives of non-governmental organizations. Data analysis was conducted using thematic analysis techniques to identify key themes that emerged from the data. The results show that a collaborative approach to tsunami mitigation has several advantages, including improved coordination among stakeholders, increased community awareness of tsunami risks, and improved local capacity in dealing with disasters. However, the study also found some challenges, such as a lack of resources and support from the central government, as well as a lack of community awareness and participation. The implication of this study is that a collaborative approach can be an effective strategy in tsunami mitigation, especially in areas with tsunami potential. The research also provides recommendations for government and non-government organizations to improve collaboration and coordination in disaster management. This research makes a significant contribution to the literature on disaster mitigation with a focus on collaborative approaches at the local level. The originality of this research lies in its focus which is rarely discussed in the literature, namely the importance of collaboration between various stakeholders in tsunami mitigation.

Abstract

Indonesia’s transition toward clean energy faces complex ethical dilemmas, particularly in the context of geothermal energy development on Flores Island. Through the Flores Geothermal Island policy, the government seeks to position Flores as a national laboratory for clean energy. However, behind the narrative of a low-carbon energy transition, social and moral tensions have emerged among the state, corporations, and Indigenous communities. This study employs a descriptive qualitative approach based on document analysis and ethical interpretivism to examine the relationship between social legitimacy, ecological justice, and public ethics in geothermal energy governance. The findings indicate the dominance of an economic utilitarian paradigm in national energy policy (40%), with a primary emphasis on efficiency and investment, while the values of ecological justice (30%), public ethics and participation (20%), and local spirituality (10%) remain marginalized. This imbalance reflects a deficit of public ethics in the clean energy transition process on Flores Island. The study highlights the need for a transformation of public ethics in energy policy, shifting from a technocratic orientation toward a paradigm grounded in social, ecological, and spiritual justice. Accordingly, clean energy should be understood not merely as a technological project but also as a moral project that respects both humanity and nature.

Abstract

Amid the challenges of fossil energy dependence and the environmental impacts associated with the road construction industry, bio-asphalt has emerged as a sustainable alternative. This study introduces BIODURIPAVE, a bio-oil derived from durian peel waste (Durio zibethinus) that serves as a partial substitute for bitumen in Hot Mix Asphalt (HMA). The bio-oil was produced through fast pyrolysis at temperatures ranging from 300°C to 500°C, yielding a calorific value of 24.674 MJ/kg and containing cellulose, hemicellulose, and lignin. The optimal bio-oil proportion was determined to be 5–8% of Pen 60/70 bitumen or Asbuton B 50/30. Test results indicate a reduction in CO₂ emissions of up to 20–30%, based on Life Cycle Assessment (LCA), along with enhanced oxidation resistance and improved mechanical stability (penetration value of 60–70, softening point >50°C, and Marshall stability >1000 kg). SWOT analysis identified the availability of local raw materials and opportunities for a circular economy as key strengths, while technological challenges related to pyrolysis and the absence of comprehensive regulations remain significant constraints. The implementation roadmap consists of four phases: research and development (2025), pilot implementation (2026), scalability expansion (2027), and national standardization (2028). The innovation is projected to reduce road construction costs by 12–15% per kilometer and generate 10–15 rural jobs for each production unit with a daily capacity of 5 tons. This innovation aligns with Sustainable Development Goals (SDGs) 7, 9, and 13.

Abstract

Technology has advanced significantly across various sectors, particularly in today's era of digitalization. Nearly everyone has become highly dependent on technology, especially smartphones. Over a 24-hour period, individuals may spend up to 18 hours using their smartphones, a duration comparable to the time devoted to other daily activities. This phenomenon occurs because most of the goods, services, and information people require are readily accessible through their smartphones. Consequently, contemporary businesses have increasingly shifted toward digital platforms. To support business growth and introduce products or services to the public, companies must implement marketing strategies. Marketing strategies can generally be categorized into two approaches: short-term and long-term strategies. In the short term, companies may adopt tactics designed to generate rapid increases in traffic and visibility, often referred to as a "hit-and-run" approach. In contrast, long-term strategies require companies to gradually and consistently establish the value of their products or services over time, thereby fostering stronger emotional connections between customers and the offerings provided. Therefore, branding strategies play a crucial role in developing and maintaining customer emotional attachment to a company.

Abstract

Pressure vessel is a container used to store fluids and is very necessary for various industrial activities. Fluids stored in pressure vessels are fluids that have special characteristics and treatment, such as fluids at low or high temperatures, pressurized fluids and so on. In general, a pressure vessel is a container made of metal. Materials that contain metal will definitely experience corrosion. Corrosion can occur, one of the reasons is because there is a chemical reaction on the metal surface caused by the low pH of the water and humid air, so that the metal becomes thinner over time. This will affect the strength of the metal to withstand pressure. The thinner the metal, the less pressure it can withstand. With corrosion, the pressure vessel's ability to withstand pressure will decrease. If the pressure held is higher than the capacity of the pressure vessel, it can cause work accidents. This research will analyze the service life of pressure vessels using inspection procedures based on Minister of Manpower Regulation Number 37 of 2016 concerning Occupational Safety and Health of Pressure Vessels and Storage Tanks. To calculate the effect of thickness on the pressure of the pressure vessel, it will be based on the formula obtained from ASME sec VIII, div.1 regarding boilers and pressure vessels. The pressure vessel that will be tested is of the Jiangsu Ashun brand at PT. Setia Gas Jaya. From the results of analysis and testing, it shows that the pressure vessels at PT. Setia Gas Jaya has the point that experiences the most corrosion, namely at the bottom-head, which was originally 6.8 mm to 6.62 mm after 2 years and 3 months of operation. The results of the analysis also show that with a working pressure of 3.3 MPa, the pressure vessel can be operational for 13 years 3 months 13 days, or its remaining useful life is 11 years 13 days starting from June 2023.

Abstract

Welding distortion is a major quality issue in heavy equipment fabrication because it affects dimensional accuracy, assembly efficiency, and production costs. This study aimed to identify the dominant causes of floor component distortion using Failure Mode and Effects Analysis (FMEA) and evaluate the effectiveness of heat input optimization in reducing distortion during the fabrication of Cool Body Truck units at PT ABC. A quantitative descriptive approach was employed using production quality records, field observations, dimensional measurements, interviews, and production documentation. Pareto analysis identified distortion as the most dominant production defect, accounting for approximately 42% of all recorded defects. FMEA results revealed that non-standardized welding parameters constituted the highest-priority failure mode, with a Risk Priority Number (RPN) of 432. Based on these findings, the welding current, voltage, and travel speed were optimized from 250 A, 28 V, and 250 mm/min to 230 A, 26 V, and 300 mm/min, respectively, reducing the heat input from 1,344 J/mm to 956.8 J/mm. Consequently, the average distortion decreased from 6 mm to 1 mm, satisfying the company's dimensional tolerance requirement of 2 mm. The findings demonstrate that integrating FMEA with heat input optimization effectively improves dimensional accuracy, minimizes rework, and enhances production efficiency in heavy equipment fabrication.

Abstract

Sineleyan Lake is one of Tomohon City’s natural assets with strategic potential as an urban public space and tourism destination supporting the Tournament of Flowers (ToF). Located in the city center, the lake has important ecological, visual, and recreational value but faces environmental challenges, including sedimentation, inadequate drainage, poor maintenance, and waste disposal. This study aims to develop a public space design for the Sineleyan Lake area by integrating digital architecture with a water analogy concept. A qualitative-exploratory architectural design research approach was employed, including site identification, contextual analysis, concept development, site planning, massing exploration, and digital visualization. The water analogy was translated into three design principles: flexibility, dynamic-static character, and transparency, which guided the development of adaptive building forms, spatial organization, and visual connections between buildings, open spaces, and the lake. The proposed design covers approximately 12,000 m² and consists of reception, management, recreation, and green open space zones. The novelty of this study lies in integrating digital architecture as a design methodology with the water analogy concept to create a context-responsive lakefront public space. This integration enables systematic form exploration, adaptive spatial planning, and digital visualization while reflecting the ecological and visual characteristics of the site. The study contributes a contextual design framework for sustainable waterfront public space development that may serve as a reference for similar urban lake revitalization projects in Indonesia.
