Abstract This study investigates the development of an oil palm trunk (OPT) high-performance flame-retardant composite derived from an inexpensive and sustainable biomass source, processed using sodium chloride (NaCl) as a low-cost flame retardant, polyvinyl alcohol (PVA) as an adhesive, and calcium carbonate (CaCO₃) as an additive. The work aims to address the inherent flammability of OPT and to enhance its mechanical performance, dimensional stability, and fire resistance in an environmentally friendly and cost-effective manner. Results indicate that a 10% NaCl treatment optimally improves the performance of the composite, increasing bending strength (MOR) from 5.95 to 12.61 MPa… More > Graphic Abstract

Abstract The total replacement of old fossil fuels poses obstacles, making the production of efficient biogasoline vital. Despite its potential as an environmentally friendly fossil fuel substitute, the life cycle assessment (LCA) of palm oil-derived biogasoline remains underexplored. This study investigated the production of biogasoline from crude palm oil (CPO) based biorefinery using catalytic cracking over mesoporous γ-Al₂O₃ catalyst and LCA analysis. High selectivity of converting CPO into biogasoline was achieved by optimizing catalytic cracking parameters, including catalyst dose, temperature, and contact time. γ-Al₂O₃ and CPO were characterized by several methods to study the physical and chemical… More >

Abstract Malaysia, as one of the highest producers of palm oil globally and one of the largest exporters, has a huge potential to use palm oil waste to generate electricity since an abundance of waste is produced during the palm oil extraction process. In this paper, we have first examined and compared the use of palm oil waste as biomass for electricity generation in different countries with reference to Malaysia. Some areas with default accessibility in rural areas, like those in Sabah and Sarawak, require a cheap and reliable source of electricity. Palm oil waste possesses… More >

Abstract The precise identification of date palm tree diseases is essential for maintaining agricultural productivity and promoting sustainable farming methods. Conventional approaches rely on visual examination by experts to detect infected palm leaves, which is time intensive and susceptible to mistakes. This study proposes an automated leaf classification system that uses deep learning algorithms to identify and categorize diseases in date palm tree leaves with high precision and dependability. The system leverages pretrained convolutional neural network architectures (InceptionV3, DenseNet, and MobileNet) to extract and examine leaf characteristics for classification purposes. A publicly accessible dataset comprising multiple… More >

Abstract The utilisation of sugar palm bunches-charcoal briquettes (SPB-CB) represents a significant advancement in biomass energy. This study aimed to analyse the properties of charcoal briquettes produced from SPB (Arenga longipes). The experiment involved categorising the dimensions of charcoal powder into three specific particle sizes: 20–40 mesh, 40–60 mesh, and particles that could pass through a 60-mesh screen. The charcoal powder will be combined with tapioca as a binding agent at three specific concentrations: 11%, 13%, and 15%. The research findings indicate that the samples underwent 60 mesh passes achieved the maximum briquette density, with an average… More >

Abstract The utilization of oil palm biomass in the production of high-value products has increased substantially. Due to the presence of sugars and starches in their tissues, oil palms have an exceptionally low natural resistance to fungi, making them susceptible to contamination. In this study, the properties of particleboard made from oil palm fibers, namely empty fruit bunches (EFB), oil palm trunks (OPT), and oil palm fronds (OPF) fibers and its potential for fungal attack were evaluated. The chemical composition, spectroscopic characterization, morphological features, and elemental analysis of oil palm biomass fibers were identified and thoroughly… More > Graphic Abstract

Abstract Globally, salinity is a brutal environmental constraint that poses a major threat to agriculture worldwide, causing nutrient imbalances and oxidative stress, leading to reduced crop yields and quality. Date palm waste from the agro-industry is a major environmental problem, but its conversion to biochar for soil amendment could help alleviate the effects of salinity stress. Pepper is a commonly grown horticultural crop that is sensitive to salinity. That’s why the current experiment was conducted with the novel idea of exploring the potential use of biochar-based fertilizer derived from date palm waste as a mitigation strategy… More >

Abstract In Saudi Arabia, drones are increasingly used in different sensitive domains like military, health, and agriculture to name a few. Typically, drone cameras capture aerial images of objects and convert them into crucial data, alongside collecting data from distributed sensors supplemented by location data. The interception of the data sent from the drone to the station can lead to substantial threats. To address this issue, highly confidential protection methods must be employed. This paper introduces a novel steganography approach called the Shuffling Steganography Approach (SSA). SSA encompasses five fundamental stages and three proposed algorithms, designed… More >

Abstract Composite materials from oil palm fiber enhance sustainability by utilizing renewable resources, reducing dependence on non-renewable materials, and lessening environmental impact. Despite their mechanical and dimensional stability limitations, oil palm fiber-based polymer composites offer significant advantages, such as natural abundance, potential weight reduction, and cost-effectiveness due to local availability and renewability. The growing interest in oil palm hybrid composites, made from blending different fibers, is due to their customizable mechanical and physical properties. Hybridization is one of the most effective methods to reinforce and improve the performance of oil palm-derived composite materials. This review investigates More > Graphic Abstract

Abstract Despite its considerable potential, oil palm trunk (OPT) remains underutilized, largely owing to the cyclical replanting process that occurs every 25–30 years. This study aimed to address this issue by developing an eco-friendly oriented strand board (OSB) using vascular bundles (VBs) from oil palm, both in binderless form and with the incorporation of natural adhesives made from sucrose and ammonium dihydrogen phosphate (ADP). The VB was extracted from OPT using a pressure cooker and mixed with a sucrose-ADP solution at various ratios. The mixture was then pressed at temperatures of 180°C and 200°C for 10… More > Graphic Abstract
