Abstract

As part of the integrated efforts that need to be made to achieve the target of becoming a world-class energy company, PHE SHU needs to carry out a series of strategic initiative programs related to the implementation of RCM which need to be carried out in several field including all Regions, Zones, Work Areas and Assets. In the context of implementing RCM at PHE SHU, management has carried out a series of massive and simultaneous activities during 2022-2023 period, both debriefing several workshops & socialization of RCM understanding, issuing task forces and director's orders, conducting site visits & field implementation pilot projects in the onshore area (GTC SKG Subang Field) as well as offshore area (GTG X-Ray Jatibarang Field), performing sharing sessions/focus group discussion, review maturity level assessment, initiate various continuous improvement and its replication to other fields, as well as database development and created Pertamina Reliability Data (PAREDA) applications.

Abstract

Oil palm fronds are currently an underutilised by product of plantations. The micro and nano cellulose can be utilised to create new goods, such as being used as a filler in environmentally friendly degradable composites. This study examined the process of extracting oil palm frond fiber (OPFF) by using a series of chemical and mechanical treatments to get pure microcrystalline cellulose (MCC). The MCC obtained by OPFF was subsequently analysed in further detail. The identification of morphological analysis, presence of functional groups, and crystallinity index were conducted using Scanning Electron Microscopy (SEM), Fourier Transform InfraRed (FTIR) and X-Ray Difraction (XRD) techniques. The findings revealed the presence of microcrystalline structures in OPF fibers, having a mean measurement of width 3.2 ± 0.42 ?m. The application of FTIR verified that the elimination of noncellulosic constituents from the treated OPF fibers had achieved its utmost level. Simultaneously, X-ray diffraction research revealed that the utilization of chemical procedures resulted the formation of a characteristic cellulose crystal structure and an augmentation in the crystallinity index. However, the mechanical treatment resulted in a minor drop in the crystalline index. This can be ascribed to the disturbance of cellulose chains and the crystal structure within the cellulose fibers. The cellulose obtained from raw fibers and subsequent processing exists in a very pure form, specifically in the cellulose I? structure. This enables its utilization as reinforcement in eco-friendly MCC-based green composites, offering numerous benefits.
