“…Besides oil palm trees, the ground area is covered with Mucuna Bracteata, a type of land cover crop purposely planted to protect the soil from weeds. Mucuna Bracteata in oil palm plantations also helps to maintain soil moisture content, supply organic matter, and protect from soil erosion [29]. Some of the trees were affected by Rhinoceros beetle (Oryctes rhinoceros L.) and other pests in the study area.…”

The information on biophysical parameters—such as height, crown area, and vegetation indices such as the normalized difference vegetation index (NDVI) and normalized difference red edge index (NDRE)—are useful to monitor health conditions and the growth of oil palm trees in precision agriculture practices. The use of multispectral sensors mounted on unmanned aerial vehicles (UAV) provides high spatio-temporal resolution data to study plant health. However, the influence of UAV altitude when extracting biophysical parameters of oil palm from a multispectral sensor has not yet been well explored. Therefore, this study utilized the MicaSense RedEdge sensor mounted on a DJI Phantom–4 UAV platform for aerial photogrammetry. Three different close-range multispectral aerial images were acquired at a flight altitude of 20 m, 60 m, and 80 m above ground level (AGL) over the young oil palm plantation area in Malaysia. The images were processed using the structure from motion (SfM) technique in Pix4DMapper software and produced multispectral orthomosaic aerial images, digital surface model (DSM), and point clouds. Meanwhile, canopy height models (CHM) were generated by subtracting DSM and digital elevation models (DEM). Oil palm tree heights and crown projected area (CPA) were extracted from CHM and the orthomosaic. NDVI and NDRE were calculated using the red, red-edge, and near-infrared spectral bands of orthomosaic data. The accuracy of the extracted height and CPA were evaluated by assessing accuracy from a different altitude of UAV data with ground measured CPA and height. Correlations, root mean square deviation (RMSD), and central tendency were used to compare UAV extracted biophysical parameters with ground data. Based on our results, flying at an altitude of 60 m is the best and optimal flight altitude for estimating biophysical parameters followed by 80 m altitude. The 20 m UAV altitude showed a tendency of overestimation in biophysical parameters of young oil palm and is less consistent when extracting parameters among the others. The methodology and results are a step toward precision agriculture in the oil palm plantation area.

“…High rates of runoff generation can be mitigated by implementing water retention managing strategies (e.g. frond piles, silt pits, biopores, planting understory vegetation) (Tarigan et al 2016, Wawan et al 2019, Devianti et al 2020, as well as preserving riparian zones to control stream properties (Luke et al 2017, Chellaiah and Yule 2018a, 2018b, Merten et al 2020. These studies are motivated by the trends in runoff regeneration, and soil erosion, and soil, when oil palm replaces forests.…”

Global demand for vegetable oil and high oil palm yield have driven the rapid expansion of oil palm plantations in tropical countries. The research literature widely recognizes the effects of forest cover conversion into oil palm on biodiversity, deforestation, and carbon dynamics. However, research on the ecohydrological impacts of oil palm plantations is sparse, despite studies indicating that oil palm development may reshape land-water interactions and the availability and movement of water at different spatial and temporal scales. We address this gap by conducting a systematic literature review on oil palm development and its relation to ecohydrological processes. We found 139 relevant papers up to the year 2021, addressing different ecohydrological processes related to oil palm. We reviewed their spatiotemporal scales, geographic distribution, oil palm species and age, and the effects of land conversion from forest, cropland, and pastures. We also incorporated societal aspects regarding community perceptions of water. Our review highlights the effects of oil palm plantations on three main components of the water cycle: i) land-atmosphere, ii) fluvial systems, and iii) soils and groundwater. Most studies include analyses of the Indo-Malayan and Australasian biogeographical regions (113), followed by the Neotropics (49) and the Afrotropics (15). Compared to rainforests, oil palm monocultures are warmer and drier. They have higher evapotranspiration rates, lower runoff regulation and infiltration capacity, and lower soil organic carbon. Although less often implemented, alternative oil palm management practices, including oil palm agroforestry, can help to mitigate some of these effects. Forest to oil palm conversion is the most studied land transition, while conversions from croplands, pastures, and grasslands are less studied. Overall, we identify gaps in understanding the long-term effects of management on ecohydrological processes under different land conversions, especially in the Neotropics and the Afrotropics, precluding research-informed policy to manage impacts of this expanding crop.

“…Laju infiltrasi air juga dipengaruhi kandungan bahan organik yang diperoleh dari hasil dekomposisi biomulsa. Bahan organik dapat meningkatkan porositas dan kestabilan struktur tanah sebagai hasil dari perannya dalam pembentukan agregat tanah yang menyebabkan jumlah pori dan aktivitas mikroba tanah meningkat (Utomo et al, 2015;Wawan et al, 2019). Porositas dan stabilitas struktur tanah yang baik dapat meningkatkan laju peresapan air ke dalam tanah (Irawan dan Yuwono, 2016)…”

Planting cover crop or biomulch as one of land conservation methods could be applied to increase the availability of groundwater. Asystasia gangetica is a plant that has the potential as biomulch on mature oil palm plantations. This research aimed to determine the roles of A. gangetica increasing water availability by improving the infiltration rate. The research was conducted on Cikabayan Experimental Field IPB from August 2020 to January 2021. The treatments were types of biomulch consisting of without biomulch, A. gangetica, Ageratum conyzoides, Borreria alata, and Arachis pintoi which were arranged using a randomized block design with five replications. The biomulches were planted on plots 5 m x 2 m. The results showed that A. gangetica had the best growth and was able to cover the soil faster than other biomulches. A. gangetica could increase the infiltration rate by 42% compared to without biomulch treatment with infiltration capacity of 20.42 cm per hour at 20 weeks after planting (WAP). Keywords: cover crop, land conservation, water availability
