Abstract

The burgeoning interest in low-emission mobility has led to a focus on Hydrogen Refueling Stations (HRS) in developing nations such as Indonesia. This study, unique in its assessment of the techno-economic feasibility of two distinct HRS configurations, delves into the cascade storage system, which involves storing hydrogen in a series of pressure vessels, and the booster compressor system, which utilizes a compressor to elevate the hydrogen's pressure. The evaluation considers projected daily demand scenarios of 413 kg/day and local economic factors adjusted for inflation. A meticulous and comprehensive discrete event simulation model was developed to encapsulate the operational dynamics inherent in each scenario under consideration. This model, which incorporates key factors such as fueling time, cascade priority logic, and hourly vehicle arrival patterns, ensures that the audience is fully informed and knowledgeable about the study's findings. In conjunction with this, an economic analysis was conducted employing the robust Levelized Cost of Hydrogen (LCOH) and Rate of Return (ROR) frameworks. The study utilized specified financial parameters, including a 5.75% real discount rate, a 15-year analytical horizon, and cost adjustments to reflect the 2025 Indonesian Rupiah. The model aims to provide a robust understanding of hydrogen fueling systems' economic viability and operational efficiency in the specified context through these methodologies. The results show that the cascade system yields a lower LCOH (IDR 41.017/kg) and capital cost per kg compared to the booster system (IDR 70.833/kg). However, both reach breakeven within 9.5 years. The booster is less advantageous in smaller-scale deployments because of its higher compression efficiency and capital investment requirements. The higher requirement for capital investment and compressing efficiency. The economic feasibility of HRS configurations may be considerably enhanced by methods to boost hydrogen sales and control capital expenditure, providing a bright future for hydrogen fueling systems.

Abstract

Product-Service System (PSS) is considered as a promising solution for manufacturing industry to address environmental and economic issues simultaneously. Despite the potential benefit, PSS uptake across industries is hardly found. This research aims to draw current state of manufacturing industry upon theoretical framework of PSS typology to get insights of the gap in between. The study exhibits PSS level assessment indicated by key character identified from the various literature of PSS typology. The study also introduces co-creation process as a strategy to increase system capability within PSS framework. Manufacturing companies are selected from various source of literature and article in PSS discussion to exercise PSS assessment. The evaluation of PSS current practice reveals that commercial based transaction (B2B and B2C) play a significant role to determine the suitable development strategy for PSS transition. Furthermore, the type of business commercial also determines the customer involvement level in co-creation process. A framework to guide PSS transition based on the business commercial is established, comprehends the type of value proposition, suitable business strategy, network configuration, and co-creation level.

Abstract

This study explores the environmental impact of beef processing operations in Surabaya, Indonesia, through the integration of Circular Economy (CE) principles and the Life Cycle Assessment (LCA) method. The analysis focuses on one of the largest slaughterhouses in East Java, examining four main stages: cattle reception, slaughtering, meat processing, and packaging. Using the ReCiPe 2016 Midpoint (H) method within OpenLCA software and the ELCD database, the study evaluates material and energy flows per functional unit of 1 metric ton of beef. The results reveal that the system is heavily dependent on fossil-based electricity and water resources, with significant greenhouse gas emissions, high freshwater usage, and unmanaged organic waste. The Global Warming Potential (GWP) category recorded the highest environmental impact, followed by fossil resource scarcity and terrestrial ecotoxicity. Waste management practices remain linear, with limited reuse or recycling efforts, while solid and liquid wastes are discharged without internal recovery processes. Benchmarking shows a considerable gap in sustainability performance compared to developed countries. The findings underscore the need for technological improvements, such as anaerobic digestion, renewable energy integration, and material recovery strategies. Implementing circular economy interventions would not only reduce environmental burdens but also add economic value through by-product utilization. This study offers critical insights for improving sustainability and resource efficiency in Indonesia’s beef industry by transitioning from linear to circular production models.
