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

Palm oil is one of the most efficient and widely consumed vegetable oils globally, but its expansion has been linked to tropical deforestation, biodiversity loss, and land use change. As global environmental concerns intensify, scholarly interest in the palm oil-deforestation nexus has grown rapidly. This study offers an updated science mapping analysis of global research on this topic until 10 July 2025. Drawing on 1,622 peer-reviewed articles retrieved from Scopus and Web of Science, we applied bibliometric analysis and science mapping to examine publication trends, thematic structures, collaboration networks, and the intellectual foundations of the field. Findings reveal a sharp increase in research output since the early 2000s, with Environmental Research Letters, Land Use Policy, and PLoS One emerging as the most relevant sources. The most prolific authors and institutions are primarily based in Europe, North America, and Southeast Asia, with the University of Göttingen and Bogor Agricultural University (IPB University) playing central roles. Indonesia now leads in single-country publications, reflecting its growing research capacity and strategic importance in the global palm oil landscape. The existing literature is predominantly framed through ecological and technical lenses, focusing on biodiversity, emissions, and sustainability certification. Keyword and co-citation analyses show emerging themes such as ‘spatial analysis’, ‘machine learning’, and expanding regional focus beyond Southeast Asia. However, critical gaps remain, particularly around social justice, land rights, and indigenous knowledge. This study highlights the need for more inclusive and interdisciplinary research approaches that foreground power dynamics, local voices, and alternative knowledge systems. Additionally, as a major producer and increasingly active research contributor, Indonesia holds strong potential to be a focus in future research agendas. The study provides a strategic foundation for researchers, funders, and policymakers engaged in sustainability and land-use governance.

Abstract

There are many challenges and obstacles that often arise when caring for agricultural crops until harvest time arrives. One of the challenges in caring for oil palm seedlings is controlling soil moisture and maintaining the right water content for the seedlings. Many seedlings die because they do not get enough water, and sometimes extreme weather conditions make it impossible to water the plants. Farmers typically do not have the time to regularly monitor soil moisture and irrigation, especially for large areas. Based on this issue, there is a solution in the form of a soil moisture monitoring system with automatic irrigation based on the Internet of Things (IoT) to assist and simplify the management of these challenges. This study aims to design a soil moisture monitoring system with automatic irrigasstion to help farmers maintain soil moisture in seedbeds. This study uses the Research and Development (R&D) method to develop the previous system as a solution to the problem and improve the previous device. The result of this study is a prototype of an automatic irrigation-based soil moisture monitoring system with a DHT11 sensor and a soil moisture sensor. This system was tested based on calibration results showing that the sensor works with a regression equation. The coefficient of determination obtained for the DHT11 sensor was 0.95 and 0.89, for the soil moisture sensor was 0.91, and for the ultrasonic sensor was 1.0. Based on the regression equation obtained, the system can respond well to changes in temperature, humidity, and water levels to monitor soil moisture in seedbeds.

Abstract

This study aims to design and assess the technical, environmental, and economic feasibility of an integrated Zero-Waste Palm Oil biorefinery for the production of Sustainable Aviation Fuel (SAF) and other value-added co-products. A quantitative-descriptive approach was employed, integrating process simulation using Aspen Plus V14, Life Cycle Assessment (LCA), and financial modeling to evaluate the system’s performance and sustainability. Primary data were obtained from operational palm oil mills. In contrast, secondary data were sourced from the International Energy Agency (IEA), the International Renewable Energy Agency (IRENA), Statistics Indonesia (BPS), and the Ministry of Energy and Mineral Resources (ESDM) during 2023–2024. The results demonstrate that the integrated biorefinery configuration, which combines thermochemical conversion pathways (pyrolysis, gasification, and Fischer–Tropsch synthesis) with biochemical processes (anaerobic digestion), achieves a mass conversion efficiency of 58.4 percent, net energy efficiency of 72 percent, and an Energy Return on Investment (EROI) of 4.97, exceeding the global bioenergy feasibility threshold of three. The LCA results indicate total Life-cycle emissions of 17.3 g CO?-eq per MJ, representing an 80.6 percent reduction relative to fossil-based Jet A-1 fuel, thereby meeting both CORSIA and RED II sustainability standards. The system also achieves a 95 percent reduction in solid residues, effectively realizing a near-zero-waste operation. Financial modeling reveals a net present value (NPV) of USD 68.2 million, an internal rate of return (IRR) of 17.6 percent, and a payback period of 6.2 years, confirming the project’s economic viability. Overall, this model establishes a scalable pathway for decarbonizing the palm oil industry through circular bioeconomy principles and positions Indonesia as a potential global hub for SAF production aligned with international carbon reduction targets.
