Combine harvester is a rice harvester that can cut the panicles of standing plants, knock down and clean the grain while crossing the rice fields. The use of combine harvester can potentially damage the soil, the soil becomes hard and the use of fuel causes potential air pollution in the rice field environment. The objectives of this study were to identify the impact of soil compaction due to the use of a combine harvester machine and to determine what physical properties affect the soil compaction due to the use of a combine harvester machine. Equipment and materials used for the sand cone test in this study include:transparent bottles, calibration funnels, plates for sand funnels, hammers, spoons, brushes, chisels, scales and sand. The results showed that soil compaction causes porosity and soil permeability was reduced so that it can inhibit plant growth. Soil compaction affects soil physical properties such as bulk density, porosity, and groundwater content.Â

Way Kambas National Park (WKNP) is home of five protected big mammals including sumatran elephants.Â It shares its border with 22 of 37 villages surrounding the national park.Â Understanding their existence in the wild is a priority, and Â wildlife genetics is a crucially needed. Besides poaching and habitat fragmentation, wildlife-human conflict is one big issue.Â Elephant Training Center (ETC) in WKNP is built for semi in-situ conservation effort on captive sumatran elephants that mainly have conflict histories with local people.Â Participative observation and bio-molecular analysis were conducted to learn the importance of captive Sumatran elephant for conservation effort. Â Through captive sumatran elephants, database and applicable methods are expected to be developed supporting the conservation of their population in the wild.Â Participative observation and molecular identification was carried on captive sumatran elephants in ETC, WKNP under multiple year Terapan grant of Ministry of Research and Technology Higher Education, Indonesia. Gene sequence and cytological analyses showed that the captive sumatran elephants are closely related and tend to be domesticated.Â Translocation among ETC to avoid inbreeding, and maintaining the captive sumatran elephant as natural as possible are highly recommended. Developing genetic database can be a reference for both captive and wild sumatran elephants.

This study aimed to know the influence of planting the flowering plants in sugarcane plantation on the index value of diversity, domination, and the eveness of phytophage and entomophage insect species in sugarcane plantation. This study was done on two-month and six-month sugarcane of PT.Â Perkebunan Nusantara VII Cinta Manis District. The research location is located in Ketiau Village, Lubuk Keliat District, Ogan Ilir Regency, South Sumatra. The study was conducted from July to December 2018. Insects that came to flowering plants were collected by using fitfall traps, nets, and direct capture of insects that came. The results showed that the age of sugarcane affected the diversity of Entomophage and Phytophage insect species that came to the flowering plants. At 2-moth-old sugar cane plantations were found 42 species (388 individuals) and 6-month-old sugarcane plantations were found 41 species (284 individuals). The diversity of Phytophage and Entomophage species that came to flowering plants inÂ the 2-month-old sugarcane plantations was almost the same as in the 6-month-old sugarcane plantations. Phytopage species diversity index values were 2,826 and 2,548, while Entomophage were 2,564 and 2,867.

Sumatran elephant is a subspecies of endemic Asian elephants on the island of Sumatra and is included in the Red List of the International Union for Conservation of Nature (IUCN) with critically endangered status. The building of the Elephant Training Centre (ETC) in Way Kambas National Park (WKNP) is one of the conservation efforts of Sumatran elephants. Small and closed population size lead to an increased risk of inbreeding that triggers reduction in genetic variation and viability and increases the risk of extinction. The phylogenetic pattern of Sumatran elephants in Indonesia has shown a low population genetic diversity. Genetic diversity information is indispensable to support the direction of decision making in Sumatran elephant conservation policy. The DNA isolation of Sumatran elephants in ETC, WKNP has performed as a first step to trace its genetic variation. The advanced step of DNA isolation is the use of cytochrome oxidase subunit I (COI) gene for identification of genetic characteristics in Sumatran elephants. The COI gene is one of the genes on the mitochondrial genome and in molecular studies it is used as a genetic marker to study genetic characteristics between species and individuals. Identification and characterisation are done by sequencing process and data analysis in the form of electroforegram using Molecular Evolution Genetics Analysis (MEGA) software version 6.0. to see the genetic diversity of the female Sumatran elephant population in ETC, WKNP. Based on the results of the analysis it is indicated that the genetic distance of 24 individual female Sumatran elephant from PLG, TNWK is 0.000 with a homology value of 100%, strengthened by the construction of phylogenetic tree. The absence of genetic distance indicates a close genetic relationship, so it can be concluded all individual female Sumatran elephants in the PLG, TNWK is derived from one population group.

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.

In the hatchery of white shrimp larvae, there are some problems, such as a decreased water quality and diseases caused by bacteria which cause a decrease in shrimp growth. The solution to reduce these problems is by applying synbiotics. This research aimed to make an innovative synbiotic formula for the absolute length growth and survival rate of white shrimp larvae (Litopenaeus vannamei) as well as the total number of bacteria and the number of Vibrio sp. In this study, there were four treatments, as follows: C-: negative control (without synbiotic application) C+: positive control (commercial synbiotic) P: probiotic 2.5 x 105 cfu/ml and prebiotic 1,5 ppm Q: probiotic 5 x 105 cfu/ml and prebiotic 1 ppm R: probiotic 7,5 x 105 cfu/ml and prebiotic 0,5 ppm S: probiotic 106 cfu/ml and prebiotic 2 ppm, each treatment with four repetitions. This research was set up in a completely randomized design experiment using twenty-four plastic tanks with 50 L total volume filled with 20 L sterile sea water and stocked with 4,000 nauplii in the PT. Citra Larva Cemerlang hatchery, Kalianda, Lampung. Variables observed in this research were survival rate, absolute length growth, total bacterial and Vibrio sp. counts, and water quality in the white shrimp larvae (Litopenaeus vannamei). The results showed that the best survival rate is in treatment S (probiotic 106 cfu/ml and prebiotic 2 ppm) (87.7%), the highest absolute length growth is in treatment P (3.8 mm), the highest total bacteria was in treatment S (11.1 log cfu/ml), and the best total Vibrio sp. is in treatment S (3.5 log cfu/ml). Water quality of the six treatments shows results that are still in normal conditions following Indonesian National Standard SNI 7311: 2009.
