“…Therefore, as a high number of N. biserrata was recorded, then N. biserrata population became the largest spacing. Land cover percentage of N. biserrata was recorded to be much higher than that of our previous finding on Asystasia intrusa, which were 74.67-82.59 % at 10 x 1 cm spacing and at 12 WAP (Satriawan et al 2020). Asbur et al (2018) stated that land cover percentage indicates plant's speed in covering an area of cultivated land.…”

“…It is of importance as a slow decomposition rate enhances the sustainability of organic deposits which is important in sustaining the fertility of the soil. Our previous finding on other cover crop weeds of A. intrusa reported greater decomposition rates with 2.43% per day and 94.6% of total biomass (Satriawan et al 2020).…”

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.

“…A. gangetica merupakan salah satu vegetasi dominan yang sering ditemukan di lahan kelapa sawit menghasilkan (Satriawan dan Fuady 2019). A. gangetica dapat meningkatkan ketersediaan hara tanah melalui dekomposisi serasah yang cepat (Asbur et al, 2018a), menambah cadangan karbon tanah hingga 119% (Satriawan et al, 2020) serta meningkatkan stabilitas agregat tanah (Junedi et al, 2015). Akan tetapi, belum banyak penelitian terkait potensi A. gangetica dalam menjaga ketersediaan air terutama dalam peningkatan laju infiltrasi.…”

Tinggi A. gangetica tidak memiliki perbedaan yang nyata pada kebun kelapa sawit umur 6,7, dan 8 tahun pada jarak tanam 20 cm x 20 cm (Satriawan et al (2020) dan nyata lebih tinggi dibandingkan Nephrolepis biserrata, Paspalum conjugatum, dan A. conyzoides di bawah naungan kelapa sawit umur 20 tahun (Asbur et al, 2018a).…”

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).

The diversity of greenery species in oil palm plantations is a source of animal feed. The research aims to identify the type of forage as a source of animal feed in the area of oil palm plantations in Watubangga Subdistrict Kolaka Regency, conducted in April to June 2021 using survey methods and direct observations on oil palm plantation areas. Observation and measurement of forage type used quadrant 1 m x 1 m in the area of oil palm plantations aged 7 years. The results of forage identification were analysed using summed dominant ratio formula to see the relative density, relative frequency and important value of a forage type. Furthermore, it was analysed using the formula of livestock capacity. The identification results showed that out of the 24 types of forage in the oil palm plantation area there are 13 types that can be consumed by livestock with a capacity of 502.07 livestock units.
