Integrated management of oil palm plantations is a key factor in increasing productivity. Analysis of land morphology in oil palm plantations is a crucial first step. The objectives of this study were (1) to characterize land morphology with LiDAR implementation, (2) to explain the LiDAR mechanism in the NDVI class classification used for determining the oil palm Vegetation Index, and (3) to provide ideas to optimize oil palm productivity. The study was conducted using the image interpretation method from the acquisition of LiDAR data which has a resolution of 3 x 3 cm in the form of DEM and orthophoto to be able to perform land surface morphology analysis (MPL) and NDVI flatfoot. The data needed in this study is Orthophoto, which is used to crosscheck field conditions, plant canopy conditions, and populations of plants per block. NDVI processing is used to determine the Vegetation Index to interpret the health of oil palm plants. The results showed that LiDAR technology can be used to determine the health of oil palm plants. The overall accuracy and reliability value of NDVI reached 88.33% and 88.13%, respectively.

Over the years, the expansion of land and the production of Fresh Fruit Bunches (FFB) of palm oil has consistently increased, accompanied by a rise in land area and crude palm oil (CPO) production. The pivotal role of Indonesia as the world’s largest palm oil producer must be highlighted through sustainability studies, especially in environmental aspects. Life cycle assessment is a technique utilized to evaluate the environmental implications of products, processes, and services, spanning their complete life cycle from the extraction of raw materials to waste management. Life Cycle Assessment (LCA) encompasses various environmental impact categories, providing a comprehensive understanding of the ecological contribution of a product or service. This research assesses the environmental impact of oil palm plantation activities in Riau province, Indonesia. The research’s boundary is set to a cradle-to-gate analysis within the oil palm plantation subsystem. The Life Cycle Assessment was conducted utilizing the SimaPro 9.5.0.0 software employing the ReCiPe 2016 method. The total emissions generated during the production process of 5 tons of Fresh Fruit Bunches (FFB) amount to 1634.22 kg CO2 eq/5 tons of FFB. The major contributors to emissions are the production and use of inorganic fertilizers. Specifically, the types of fertilizers responsible for the high greenhouse gas emissions are KCl, followed by phosphorus and nitrogen fertilizers. Besides the potential for global warming, human carcinogenic toxicity is another potential impact, primarily from fertilization. The findings in this study can serve as scientific evidence in formulating solutions for sustainable oil palm plantations, particularly in reducing greenhouse gas emissions. An environmentally conscious approach to lowering emissions requires meticulous scrutiny and implementation of precision farming. It chiefly involves keeping a close watch on the quantity of fertilizer used in plantation settings and promoting using fertilizers with lower carbon footprints.","PeriodicalId":14556,"journal":{"name":"IOP Conference Series: Earth and Environmental Science","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141945146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper investigates the current status and future potential of RES deployment across eleven countries in the region: Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Kosovo, Montenegro, North Macedonia, Romania, Serbia, and Slovenia. In this comprehensive analysis, we begin by providing an overview of the installed capacity of RES in these countries for the year 2021, drawing upon data from reputable sources such as the International Renewable Energy Agency (IRENA) and national energy agencies. Building upon this foundation, we delve into an in-depth examination of the wind and solar energy potential in the region, utilizing geographic information system (GIS) data and modelling techniques to assess resource availability and feasibility. Furthermore, we explore two distinct scenarios for maximizing solar energy deployment in the Balkans. Firstly, we analyse the implications of covering the entire territory of each country with solar panels, estimating the potential electricity production and its relation to current consumption levels. Secondly, we use a more pragmatic approach, focusing on the strategic deployment of solar panels in areas with the highest energy generation potential, while considering land use constraints and environmental considerations. In addition to evaluating the technical and economic aspects of RES deployment, we also quantify the environmental benefits in terms of carbon emissions reduction. By comparing emissions from renewable sources with those from conventional fossil fuel-based electricity generation, we highlight the significant contribution of RES to mitigating climate change and achieving sustainability goals. In conclusion, this paper underscores the immense potential of renewable energy in the Balkans and emphasizes the importance of strategic planning and policy interventions to unlock this potential. By leveraging the region’s abundant natural resources and embracing innovative technologies, the Balkan countries can chart a course towards a more resilient, equitable, and sustainable energy future.","PeriodicalId":14556,"journal":{"name":"IOP Conference Series: Earth and Environmental Science","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141945150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
