“…Herbs are also adaptable to climate change, have allelopathy, and reproduce through seeds and stolons that spread easily. Old herb seeds are usually covered with fur and are small so that they are easily carried by wind and water or attached to the bodies of animals and humans (Widarta et al, 2020). This character makes herbaceous species generally pioneer plants.…”

Overburden (the dumping of mine tailings and other reject materials) from the Warukin geological formation is one of the potential acid-forming (PAF) of 33.17%. Mining can cause overburden to be exposed and affect biotic and abiotic conditions. The study aimed to analyze the biotic and abiotic factors of three different age overburdens from the Warukin Formation, South Kalimantan. Biotic factor measurements included vegetation sampling using line transect, soil insects using pitfall traps, and microbial using total plate count. Abiotic factor measurements included air temperature and humidity, light intensity, temperature, moisture, and pH of the substrate (n=3), and chemical overburden. Identification of plants and insect species using information from locals, identification books, and websites. Plant species diversity was analyzed using the Shannon-Wiener Index. Dominance species were analyzed using the Important Value Index (IVI). The relation of overburden age on biotic and abiotic factors was analyzed multivariate with Non-Metric Multidimensional Scaling (NMDS). The results showed that there are 102 species of plants and 11 species of soil insects. The numbers of fungi and bacteria are 10-4 CFU g-1 and 10-3 CFU g-1, respectively. Plant species diversity is classified as medium (H'= 2.34; 2.50 and 2.82). Changes in plant composition occurred as the microclimate and substrate nutrition improved. The organic matter increased over time. Humidity and light intensity influence the presence and composition of organisms, while pH values affect the adaptability of plants, insects, and microbes. Heavy metal concentrations have increased due to the physicochemical properties of the Warukin formation overburden.

“…This is because monocultures from oil palm plantations only focus on one type of oil palm. In addition, this type of plant species diversity is considered to be a competitor for oil palm in obtaining water and nutrients [7]. [8] revealed that undergrowth in oil palm plantations is often seen as weeds that are considered to competewith oil palm for nutrients, so plantation management overcomes with weeding and herbicides.…”

The level of plant species diversity in oil palm plantations is thought to be decreasing in number. The existence of other plant species is considered to be a competitor for oil palm plants in obtaining water and plant nutrients. Thus, the diversity of plant species gets less attention because they are considered to have no role. We address this problem by analyzing the level of plant species diversity and the role of plant species diversity in maintaining the ecological balance in the plantation environment. This research was conducted on 4 types of landcover in TPR oil palm plantations (young growth, medium growth, old growth, HCV) and 2 smallholder oil palm plantations, by vegetation analysis with the single plot method. The results showed that the number of species on the research site was 49 species. The highest value of species richness and diversity was obtained in smallholder oil palm plantations (Dmg=3.11 and H′=2.18), while the highest evenness value was found in old growth (E=0.79). Based on the literature study, there were 23 species that have a direct ecological role in oil palm plantations. The ecological role of plants in oil palm plantations are as a ground cover for regulating soil moisture (4 species), producing litter for nutrient formation (5 species), fertilizing the soil and absorbing toxins (3 species), regulating water management and preventing erosion (3 species), increase soil carbon stocks and groundwater availability (2 species), animal feed (5 species), feed for wildlife (6 species), control pests and diseases (4 species), etc. The ecological role of this plant species will have a positive impact on oil palm plantations, especially in maintaining soil fertility, availability of groundwater, providing feed for animals, and also as biopesticides for oilpalm plants to avoid pests and diseases.
