Indonesia has a serious waste problem, which ranking second in marine pollution. Due to significant environmental impacts, a solution to overcome the complexity of waste problems is needed. This study took sample on waste management in Jakarta Industrial Estate Pulogadung (JIEP). JIEP is an Industrial area which covers 443 hectares of land in East Jakarta. This study aims to address Indonesia's serious waste problem by exploring the potential utilization of waste in the Jakarta Industrial Estate Pulogadung (JIEP) as Refuse-Derived Fuel (RDF) for a waste-to-energy (WtE) power plant. The proposed method used a steam power plant with RDF as fuel …

The synthesis of carbonaceous materials for reduced graphene oxide (rGO) precursors using oil palm empty fruit bunches waste as a carbon source offers a sustainable solution for waste management in the palm oil industry while delivering high-performance materials. The oil palm empty fruit bunches were carbonized, followed by acid washing, pyrolysis with ferrocene (8%, 12%, and 16% variations), and ultrasonication to produce rGO. The structural, electronic, and morphological properties of the rGO were analyzed using various characterization techniques. The band gap values decreased with increasing ferrocene concentration, from 1.14 eV (8%) to 1.06 (16%), indicating enhanced electronic conductivity. XRD analysis …

One of the key challenges in asset integrity management system at offshore platform is the lack of visibility regarding performance issues and program effectiveness. Without proper performance measurement systems, it becomes difficult to address positive or negative trends promptly and for management to stay informed about the status and the impact of the inspection program. Therefore, Key Performance Indicator (KPI) is needed to measure inspection program effectiveness to prevent undesirable equipment failures that could lead to Loss of Primary Containment (LOPC) or Process Safety Event (PSE). The developed KPI is the ratio of the number of non-leak inspection findings with …
