A research to monitor the presence of Sumatran elephant between two ecosystem in Sembilang National Park (TNSTNS) and palm palm oilplantation has been conducted on March until June 2019 at Semenanjung Banyuasin Semenanjung, South Sumatra. This research aimed to verify the presence of Sumatran elephantpopulation and to estimate the number of elephant individuals in the area. The methods used weredirect observation during the day and indirect monitoring through installation of Camera Traps for 1 month. In addition, secondary data was collected in the form of data archives from the palm oil plantation records and interviews with affected plantation workers. From direct observation, Wedirect encountered one elephant individual and fifteen signs of elephant activities, such as sounds, footprints, and feces. From camera trap photos, we identified and verified onepopulation of Sumatran Elephants which consisted of at least twenty-two individuals with composition as follows: eight adult females, two young females, three infant females, and nine males. The ecotone area between TNS and palm palm oil plantation should be designated as a new habitat patchof Sumatran elephant that needs to be managed appropriately in order to maintain the designation of the area as aÂ conservation area.

Sumatran Elephants (Elephas maximus sumatranus) is one of the endemic Sumatran fauna that is protected by Indonesia Law. The Remnant Forest of Acacia District Penyabungan in the landscape of Padang Sugihan is one of the elephantâ€™s habitats in South Sumatra. Habitat degradation and fragmentation, poaching and conflicts become the major threats for the elephant population. Genetic study is one of the efforts to establish a conservation policy. It is necessary to test the quantitative and qualitative of DNA, at the extractions stage from fecal samples, in order to get the standard results on DNA concentration which will be analyzed later. The method used is through direct observation as the initial survey to determine the sampling location. Fecal samples were preserved in absolute ethanol at -20Â°C.Â The extraction process was carried out using the Quick-DNATM Fecal/Soil Microbe Miniprep Kit. Samples were tested quantitatively using a Nanodrop Thermo Scientific, with the expectation that the concentration results were considered to be 1.6-1.8 and continued with the qualitative test of DNA through electrophoresis gel agarose and UV Transilluminator. Of the 20 samples, only 12 samples showed positive results (there were DNA bands). The results of this quantitative and qualitative test could be used to determine a viable sample to be used as a product in the genetic analysis stage of Sumatran Elephants in the Remnant Forest of Acacia South Sumatra.

Nowadays in the Kurdistan region of Iraq, the number of patients have common symptoms with COVID-19 infection rapidly increased. 123 patients which they had common symptoms with COVID-19 and 94 healthy control individuals (non-COVID-19) were subjected for quantitative analysis for each one of the following biochemical parameters, Lactate dehydrogenase (LDH), Creatine Phosphokinase (CPK), and C-reactive protein (CRP) in Erbil, Kurdistan Region of Iraq. We analyze clinical features and compared the differences between COVID-19 and non-COVID-19 symptoms. Among the healthy control individuals, the absolute value of LDH, CPK Creatine Kinase and CRP were determined in between the normal range, and in compare with patients with COVID-19 symptoms their values were smaller and, the P value was (P ＜0.05). All three biochemical parameters increased among patients with COVID-19 symptoms, but more significantly, steadily increase was observed only in LDH value in age above and under 40 years (284.43±10.29 and 321.23±16.32 U/L), and p-value was (0.0488). Male patients had higher levels of LDH (299.32±11.42 U/L), CPK Creatine Kinase (195.90±26.65 mg/L), and C-Reactive Protein (5.86±3.96 mg/L) in compared with the female patients. Our study suggested that among patients who have COVID 19 symptoms, increased LDH is the advised and helpful biochemical marker among routine panel for COVID-19 infection evaluation. Also, CRP levels were positively correlated with male patients when compared with the healthy control.

The initial phase of the fish life cycle is a critical phase associated with high mortality due to sensitivity to predators, food availability, and also environmental changes that occur in nature. Disruption of the initial stages of fish life has a negative impact on fish populations. Until now there has been no information about fish larvae around the Banyuasin River Estuary. Therefore, research is needed on the diversity of fish larvae around the Banyuasin River Estuary, South Sumatra Province. This research were used purposive sampling method, sampling technique in the form of Cruise Track Design with continuous parallel survey trajectory. Based on the results of the study found as many as 10 families consisting of 1483 individuals of fish larvae in March and 1013 individuals of fish larvae in May consisting of Engraulidae 1,601 individuals of fish larvae, Mungiloidei as many as 109 individuals, Leiognathidae 50 individuals, Chanidae 453 individuals, Scatophagidae 20 individuals , Belonidae 39 individuals, Gobioididae 5 individuals, Chandidae 183 individuals, Syngnatihidae 6 individuals, and Gobiidae 30 individuals fish larvae. The index value of fish larvae diversity is classified as medium category (March 1.02 and May 1.12), Morisita index shows the distribution pattern of fish larvae classified as a group (March 0-14.17 and May 2.43-10.40 ), and the evenness index value is in the medium category (March 0.437 and May 0.521).

Coal mining activities have affected the soil and vegetation conditions on the mined land. Revegetation of ex-mining land is a must to balance environmental functions. The choice of plants must be adapted to the conditions of the ex-mining land so that growth continues. The use of local plants for revegetation is fascinating to study. This study aimed to investigate the soil characteristics of ex-coal mining land and bamboo growth as a plant used for revegetation. Bamboo is collected from around the former coal mining area. Bamboo growth is observed through its branching for 12 weeks of measurement. Soil is analyzed based on its physical and chemical properties. The Schmidt-Ferguson method was used to analyze the climate type in the study area. The results of the soil analysis show that the plants can still grow for revegetation. Of the three types of bamboo observed (Schizostachyum brachycladum kurz, Dendrocalamus asper, and Gigantochloa robusta), Schizostachyum brachycladum kurz is the best growing bamboo in ex-coal mining land with a branch length of 42 cm in 12 weeks of measurement. The climate in the ex-coal mining area studied is a wet type (Q = 0.184). Bamboo is a suitable plant for revegetation, especially in coal mining areas in South Sumatra, Indonesia.

Coal mining can disrupt the balance of the ecosystem, including the soil environment ecosystem as a habitat for soil arthropods. This study aims to see the soil arthropod family, relative density, diversity, dominance and evenness of soil arthropods in the revegetation area of the ex-mining area of PT. Bara Alam Utama. The re-search was conducted in the revegetation area of the former coal mine area of PT. Bara Alam Utama in Lahat district, South Sumatra. The research area consists of 8 location points, namely natural areas, revegetation areas of age 7,6,5,4,3,2 and 1 year. The study was conducted using an exploratory survey method, sampling was car-ried out based on the purposive sampling method by drawing a 100 m long transect with 5 sample plots inside measuring 20 x 10 m at each revegetation age. The results showed that the highest soil arthropod diversity index was found at the 3 year old revegetation location (H = 0.915) and the highest soil arthropod evenness index was at the 3 year old revegetation location (e = 0.17), while the highest soil arthropod dominance index was at 5 year old revegetation location (D = 0.886) which causes the 5 year revegetation location to have the lowest soil ar-thropod diversity index and evenness index (H = 0.351 and e = 0.054), while the lowest soil arthropod domi-nance index value is at the 3 year old revegetation location (D = 0.667), so it can be seen that there is a correla-tion between the diversity index and the evenness index of soil arthropods where both are inversely proportional to the results of the calculation of the dominance index. The high and low diversity index at each research loca-tion is influenced by abiotic factors (pH, soil temperature and soil moisture), age of revegetation and type of vegetation
