International Journal of Oil Palm (IJOP) is an online and print mode, a peer-reviewed research journal published by Indonesian Oil Palm Society (Masyarakat PerkelapaSawitan Indonesia, MAKSI), it provides a global publication platform for researcher, scholars, academicians, professionals and students engaged in research in oil palm industries. The main aim of IJOP is to become the world’s leading journal in oil palm that is preferred and trusted by the community through publishing authentic, peer-reviewed and scientifically developed research articles of international caliber. The journal is published three times in a year, 6-10 papers per publication, and the language of the journal is English. JOURNAL SCOPE IJOP publishes research papers in the felds of soil and crop fertilizer application, seedling preparation, cover crop management, leaf pruning, weed control, control of pest and diseases, insect pollinators management, water management, intercropping, cattle oil palm integration, environmental studies, harvesting technology, IT remote sensing GPS application, mechanization, sustainability standards, policy studies, social and economic studies, smallholders empowerment, palm oil mill improvement, biomass utilization, carbon footprint, water footprint, market studies, refinery, food and nutrition technology (oleofood, food safety, pharmaceutical, and nutraceutical) and also management of soil preparation, inorganic and organic safety, oleochemicals, downstream industry development, supply chain, and market studies. The published articles can be in the form of research articles, review paper or short communications which have not been published previously in other journals (except in the form of an abstract or academic thesis/dissertation or presented in seminar/conference).

Abstract

Indonesia's coastal oil palm plantations face unprecedented threats from accelerating sea level rise, with regional rates of 4–5 mm year?¹ significantly exceeding global averages. This study presents the first comprehensive satellite-based assessment of sea level rise impacts on coastal oil palm vulnerability, focusing on Dumai City, Riau Province. We utilized five primary datasets spanning from 2020–2024: Landsat 8/9 and Sentinel-2 imagery for plantation mapping, SRTM DEM for topographic analysis, satellite altimetry for sea level measurements, and ground truth data for validation. Cross-wavelet analysis revealed an exceptionally strong negative correlation (r = -0.857) between sea level anomalies and coastal land cover changes, with a 30-day lag period indicating plantation ecosystem response time. NDVI trend analysis showed significant vegetation decline (-0.072 NDVI/year) over the study period, with plantation health deteriorating from optimal conditions in 2020 (mean NDVI: 0.608) to critical levels by 2024 (mean NDVI: 0.335). Land cover change detection revealed extensive palm oil expansion (+4,848 ha, +26.3%) occurring through conversion of natural forest (-3,114 ha, -22.8%) and mangrove ecosystems (-1,300 ha, -19.5%). Results reveal that 78% of coastal oil palm plantations are located within 5 km of shoreline on low-lying areas with elevations below 3 meters above sea level. The vulnerability assessment identified 2,847 hectares (64% of total coastal plantations) as highly vulnerable to inundation and saltwater intrusion, representing USD 12.3 million in annual production value at risk.

Abstract

Palm oil adulteration poses significant health and economic risks, necessitating accurate detection methods. This study develops a machine learning framework combining KNN, SVM, and Random Forest via weighted model averaging to analyze synthetic FTIR spectra simulating pure and adulterated palm oil. SVM emerged as the top performer (97.3% accuracy), significantly outperforming Random Forest (86.9%) and KNN (85.9%). Principal Component Analysis revealed distinct clustering, with PC1 (63.3% variance) strongly correlate with key adulteration markers like ester C=O (1745 cm?¹) and OH (3300 cm?¹) vibrations. Spectral segmentation identified the 1000–1100 cm?¹ region (C-O stretches) as most critical for detection, enabling a proposed two-stage screening protocol that reduces analysis time by 60% while maintaining >90% accuracy for 5% adulterant concentrations. The synthetic dataset, validated against experimental references, replicated physicochemical trends, including peak broadening in oxidized samples (+20% FWHM) and dye-specific N=O peaks (1520 cm?¹). Model averaging enhanced stability, reducing performance variability to 1.2% versus 3.5–4.8% for individual models. These results highlight SVM’s superiority in handling high-dimensional spectral data and non-linear patterns, while the methodological advances—including noise modeling (SNR = 40 dB) and feature selection—offer practical solutions for portable FTIR devices. The framework supports real-time adulteration screening in resource-limited settings, with implications for food safety regulation and IoT-based quality monitoring in global palm oil supply chains.

Abstract

Palm oil, a native crop of West Africa, emerged as a key industrial commodity in the 19th century, fundamentally shaping economic and environmental landscapes in both Europe and Southeast Asia. While its importance in European industrialization has been widely acknowledged, the early colonial expansion of oil palm cultivation in Indonesia and its impact on deforestation remains less discussed. This paper explores the intertwined economic, political, and environmental dimensions of palm oil trade in Europe post-1800 and the early plantation-based land conversion in Indonesia before 1945. Drawing on archival sources, historical records, and academic studies, it highlights the dual role of palm oil as both an enabler of industrial progress and a driver of ecological transformation.
