The expansion of oil palm plantation has been claimed as a major driver of biodiversity loss in the tropics, including birds. To date, only a few studies have been conducted to document the variation of bird diversity in different land cover within oil palm plantation. Therefore, it is necessary to conduct the research to investigate the variation of bird diversity. The objective of this study to identify the diversity of bird in different land cover within oil palm plantation. The observation of bird diversity was done in young stand of oil palm, old stand of oil palm, smallholder oil palm and in secondary forest as high stock carbon as natural reference before converting in to oil palm. The survey was done in August 2017 in Central Kalimantan, Indonesia. Data of bird species were recorded by direct observation using transect method. To calculate the diversity value of birds at different land cover, we used Margalef Index (Dmg) and Comunity similarity (IS). The result showed that the number of species and species diversity was highest at high carbon stock area which the number of species was 25 species and Margalef Index was 5.99. The young stand of oil palm have the highest evenness index (0.93), while the highest similarity index was observed in old stand of oil palm and in smallholder oil palm. Our study concludes that the existence of high carbon stock areas within oil palm plantation had a positive influence in increasing bird diversity. From a conservation perspective, retaining of natural habitat such as high carbon stock within oil palm plantation is one strategy to conserve biodiversity.

Abstract. Satriawan H, Fuady Z, Ernawita. 2021. The potential of Nephrolepis biserrata fern as ground cover vegetation in oil palm plantation. Biodiversitas 22: 4808-4817. Nuisance plants or weeds are commonly found in agricultural landscapes including in oil palm plantations. Despite being considered as weeds, several of them have the potential to be used as ground cover vegetation including Nephrolepis biserrata (Sw). Schott. This fern species exhibits beneficial characteristic as ground cover plant especially in terms of the contribution of organic matter and soil moisture through the prevention of evapotranspiration. The objective of this research is to explore the potential of N.biserrata as ground cover vegetation in oil palm plantations based on the assessment of its ecological characteristics regarding the growth and decomposition rate, tolerance to shade, organic contents and carbon accumulation. The split plot experimental design was used with the age of oil palm plants was used as main plot while in the sub-plots the spacing of N. biserrata was used at three varying distances 10x10cm, 20x20 cm, and 30x30 cm, each treatment had three replicates. Nine parameters observed were the percentage of growth, the percentage of ground cover, plant height, fronds number per plant, leaves number per plant, Leaf Area Index, dry weight (g), nutrient content in plant tissue, and potential carbon stock. Results showed that N. biserrata showed rapid growth in covering the ground surface (8-12 weeks after planting), had rapid decomposition rate (30-60 days), tolerant to shading which was characterized by the highest percentage of growth up to 81.16% and covering area up to 95.9%, accumulated organic contents of N (1.23-1.53%), P (0.18-0.22%), and K (1.4-1.67%), respectively. In addition, total dry weight biomass obtained was 27.1 ton/ha, accumulated carbon in plant of 0.9 tons C/ha/year, and amount of soil carbon stock 76.4-97.4 tonnes/ha/year. The results of this study suggest that Nephrolepis biserrata is a potential plant to be utilized as a ground cover plant in oil palm plantations.

Oil Palm Plantation

Kelapa sawit merupakan salah satu tanaman meningkat paling pesat di dunia, dan mencakup lebih dari 13 juta ha di Asia Tenggara. Sumatera memiliki sejarah yang relatif panjang budidaya kelapa sawit komersial, dan banyak perkebunan telah menggantikan hutan hujan. Biasanya ini perkebunan monokultur mendukung spesies lebih sedikit daripada hutan, namun ada sangat sedikit informasi yang tersedia untuk kelelawar. Kami mencicipi kelelawar pemakan serangga di Sumatera Barat dalam perkebunan kelapa sawit matang di mana beberapa tutupan hutan dipertahankan di fragmen hutan di bukit-bukit dan di sepanjang sungai. Menggunakan total 180 kecapi perangkap malam kami dibandingkan dengan komunitas kelelawar dalam tiga jenis habitat: patch hutan, zona riparian dan perkebunan. Total kami ditangkap 1108 kelelawar yang mewakili 21 spesies dan 5 keluarga, dan mayoritas ini (dalam hal spesies dan kelimpahan) ditemukan di fragmen hutan. perkebunan kelapa sawit ditemukan menjadi habitat miskin untuk kelelawar - hanya empat orang dari dua spesies ditangkap. daerah pinggiran sungai didukung keanekaragaman menengah, dan mungkin penting sebagai koridor satwa liar antara fragmen hutan. Kata kunci : Biodiversitas, keleawar Microchiropteran

The Relationship

The aim of this study is to analyse the relationship between vegetation indices of Normalized Difference Vegetation Index (NDVI) and soil nutrient of oil palm plantation at Felcra Nasaruddin Bota in Perak for future sustainable environment. The satellite image was used and processed in the research. By Using NDVI, the vegetation index was obtained which varies from -1 to +1. Then, the soil sample and soil moisture analysis were carried in order to identify the nutrient values of Nitrogen (N), Phosphorus (P) and Potassium (K). A total of seven soil samples were acquired within the oil palm plantation area. A regression model was then made between physical condition of the oil palms and soil nutrients for determining the strength of the relationship. It is hoped that the risk map of oil palm healthiness can be produced for various applications which are related to agricultural plantation.

Development of oil palm plantation on peatland was faced with hydrophobicity problem caused by over drained. Hydrophobicity could reduce water retention and nutrient availability in the peat soil. Beside of proper water management application, addition of soil ameliorant which contain iron could increase stability and improve peat soil fertility. The study was conducted to obtain the effect of steel slag on peat soil properties and hydrophobicity. In this study, peat soil was incorporated with steel slag and incubated in 60 days period. The research was employed completely randomized design (CRD) factorial 2 x 2 x 4. First factor is peat maturity consists of two levels: sapric (S) and hemic (H), while the second factor is soil moisture which also consist of two levels: field capacity (W1) and dry (under the critical water content) (W2). The third factor is steel slag dosage which consist of four levels: 0 g pot (TB0), 7.17 g pot (TB1), 14.81 g -1 -1 pot (TB2), and 22.44 g pot (TB3). The result showed that application of steel slag significantly increase of soil pH, ash content, and water retention at pF 4.2. Furthermore, application of steel slag significantly reduce time for water reabsorption (wettability) in sapric. On the other hand, there are negative corellation between water penetration and soil pH, ash content, and water retention at pF 4.2. Overall, application of steel slag could increase wettability and prevent peat soil hydrophobicity.
