Abstract

Urban forests hold potential as carbon sinks while also providing vital ecosystem services. This study aims to analyze the carbon sequestration potential of Cipayung and Munjul Urban Forests in East Jakarta and to offer policy recommendations for the Jakarta Provincial Government. Field measurements were conducted using Diameter at Breast Height (DBH) data, which were collected through stratified random plot sampling. Biomass was estimated using the IPCC (2006) allometric equation, combined with species-specific wood density values. The results show that Cipayung Urban Forest sequesters approximately 111.52 tons CO₂ eq, while Munjul Urban Forest sequesters 42.10 tons CO₂ eq. These differences are influenced by vegetation structure and species composition. Ecologically, urban forests contribute to local greenhouse gas reduction while supporting adaptation to extreme weather, including reducing urban temperature and improving water absorption capacity. Policy implications include the need for the Jakarta Provincial Government to strengthen urban forest protection regulations, integrate urban forests into spatial planning, and enhance participatory community-based management. The limitation of this study lies in its coverage, which was restricted to only two urban forests; therefore, future studies should expand to other urban green areas across Jakarta.Keywords - Carbon Sequestration, Jakarta, Urban Forest.

Abstract

PT XYZ is a manufacturing company that provides hot metal transportation handling services and supports Blast Furnace (BF) operations at the Krakatau Posco Plant using heavy equipment, namely Multi Mover M600U. To ensure smooth production processes, effective and efficient maintenance management of the heavy equipment are essential to enhance reliability. This study evaluates potential failure modes, their impacts and appropriate handling measures for the Multi Mover M600U using the Failure Mode and Effect Analysis (FMEA) method. The result of the study shows the highest Risk Priority Number (RPN) value of 350 in the Electrical PLC component, with a total RPN of 777 for the Electrical and Brake systems. These findings indicate that the Electrical and Brake systems have the highest failure rates due to downtime compared to other systems. Through the Reliability Centred Maintenance (RCM) approach, this study proposes a maintenance scheduling plan to minimize the risk of sudden downtimes, and their impacts on time and maintenance costs.Keywords - Downtime, Failure Mode and Effect Analysis, Heavy Equipment Maintenance, Reliability Centred Maintenance, Risk Priority Number.

Abstract

Supply chains must be able to adjust quickly in a dynamic and uncertain global business environment. The VUCA (Volatility, Uncertainty, Complexity, and Ambiguity) era demands that organisations and their alliances be proactive in anticipating and responding to change, rather than merely reacting to it. Supply chain agility is a crucial component that enables businesses to adapt, innovate, and maintain their competitive edge in rapidly changing market conditions. Building supply chain agility is therefore essential for maintaining business continuity and ensuring customer satisfaction. Previous literature from 2019 to 2025 was analyzed using a content analysis approach that aims to discuss the role of strategic leadership in building Supply Chain Agility (SCA). In this context, the role of innovation and digital transformation is shifting the paradigm from proactive to transformative. Dynamic capabilities serve as amplifiers, magnifying the positive effects of strategic leadership on supply chain agility. Resource orchestration bridges the gap between leadership decisions and the supply chain's achieved level of agility. This study affirms organisations need to consider building agility in conjunction with technological investment and process restructuring. However, organisations must prioritise the quality of strategic leadership that is capable of navigating uncertainty. Strategic leaders drive innovation, resilience, and cross-boundary collaboration within supply chains.Keywords - Digital Transformation, Resource Orchestration, Strategic Leadership, Supply Chain Agility, VUCA.
