Hydrogen sulphide is a chemical compound that carries the formula H2S a colourless, combustible, to a great degree perilous gas with bad smell. It happens normally in raw petroleum, flammable gas, and hot springs. Furthermore, hydrogen sulphide is removed from the gas related the oil and is isolated by warm and is prepared and heightened to encourage the procedure of exchange where it is traded to other foreign countries. It used as a part of the make of a few medications and is generally used as a part of substance analysis. Industrial activities that can produce the gas include crude oil, natural gas drilling and refining. The research aims to Simulate & study different options to enable H2S removal from crude oil in oil and gas plant. In previse literature; the searching of hydrogen Sulphide is the chosen strategy for decreasing the corrosion and operational dangers in oil production facilities. Hydrogen Sulphide removal from multiphase created fluids preceding phase partition and preparing by injection of EPRI H2S scrounger arrangement into the gas phase by using the considered chemical system relates to a standing oil well. As a result, three different methods were used in this study to extract H2S from heavy crude oil: a stabilization column, a stripping column, and a heater and knock drum. The research carried to study of hydrogen Sulphide removal from heavy crude oil using UNISIM software version 400. The result of project is choosing the best options based technical and economic selection is stripping column. After completely understanding the research, it can presume that data said through it, in reality is recipient to comprehend the human effect of hydrogen Sulphide gas.

Here for the first time, an electronics feeling side or anti-hypertension molecule of 2,6 diethyl pyridine in herbal medicine based Galoba fruits (Zingiberaceae sp.) is calculated and reported to have one of the main contribution parts in multitasking physics of natural healing system of “1 medicine with 7 spirits” with the total resistant is 3.319 Rc, where Rc is the carbon resistant. Such feeling natural healing system part was identified from a series of detailed investigations involving theoretical model and calculation, medical tests to HIV virus, inhibition test with a comparison with a world standard chemotherapy drug such as cisplatin, and pharmacology deep research using gas chromatography mass spectrometry (GCMS) with a unique finding of 21 essential chemical substances associated with a multitasking healing organization. These significant natural findings are attractive because of its differences from the normal drug system in which many costumers and pharmacy companies got more benefits by producing 1 excellent drug to 1 target.

Research on Hydroseeding is considered few in Indonesia. The application of this technique is possible for landslide management. to analyze the effect of slope and hydroseeding formula on the percentage growth, germination height, and number of leaves of Poeraria javanica planted on landslide-used soil media. This research was conducted in the Central Laboratory and the green house of the Malang Institute of Agriculture in March-July 2020. The soil media used were obtained from landslides in Ngantang, Malang Regency. A total of 5 kg of media was put into the plastic boxes. Then the boxes were placed on a shelf with a slope of 30°, 50°, 70°. The Tropical Kudzu seeds obtained from the market were mixed with compost, soil conditioner, guar gum, water to form a Hydroseeding formula. The formula was sprayed onto the planting medium. The results indicated that the slope level was significantly affected the growth percentage (P = 0.018), shoot height (P = 0.015), and the number of leaves (P = 0.010). The study indicated that the growth percentage, shoot height, and the number of leaves of the Tropical Kudzu (Pueraria javanica) were significantly affected by the slope level and hydroseeding treatment. The highest growth was found on 50° slope, while the lowest was on a slope of 70°. The highest sprouting height was at a slope of 50° while the lowest was at a slope of 70°. The highest number of leaves was at a slope of 50°, while the lowest was on a slope of 30°. Thus, the Tropical Kudzu (Pueraria javanica) can be used as a pioneer plant in land reclamation.

Clove oil microencapsulated with maltodextrin as an antifungal agent against Candida albicans could produce different clear zones. A ratio of clove oil to maltodextrin of 1: 4 yielded clear zones in the medium group. Meanwhile, other ratios of 1: 6, 1: 8, 1:10, and 1:12, including the antifungal properties of clove oil, yielded clear zones in the strong category. The one-way ANOVA test results showed Fscore = 22.56 > Ftab(α = 0.01) = 5.06; indicating that at least one average clear zone diameter differed significantly from those of other treatment groups. HSD test shows that ratios of 1: 4 and 1: 6 obtained |Yi−Yj| > HSD, meaning that the coating has a negative effect. Meanwhile, in the ratios of 1:8; 1:10, and 1:12, the HSD test showed that |Yi−Yj| < HSD, meaning that the presence of maltodextrin did not affect. The increase in coating material was suspected to result in a more extensive distribution of clove oil in the coating material, thus increasing the interaction with Candida albicans.

Tuberculosis is a contagious disease caused by mycobacterium tuberculosis, which is transmitted through aerosols or droplet nuclei into the air when a person coughs, sneezes, or talks and is then inhaled through the airway. In this study, a mathematical model will be formulated to describe the spread of tuberculosis with the DOTS strategy using the SEIT type epidemic model. Furthermore, the obtained mathematical model will determine the type of stability, look for the basic reproduction number (R0), then simulate the model using MatLab. From the analysis of the model carried out, it was obtained two equilibrium points, namely the disease-free equilibrium point F0=(S0,E0,I0,T0)=(αμ,0,0,0) and the endemic equilibrium point F1 (S*, E*, I*, T*). By using the Routh-Hurwitz criterion, it is obtained that the type of equilibrium from the two equilibrium points is asymptotically stable. The model analysis carried out also produces a basic reproduction number (R0) whereby, R0 > 1 is obtained or the spread of tuberculosis is endemic. Furthermore, the model simulation is carried out using MatLab software with a variation of the parameter value ω (rate of active tuberculosis patients undergoing treatment with the DOTS strategy), the higher the parameter value ω, the less the spread of tuberculosis is.

The waters of the Spermonde Islands are one of the habitats for the marine biota of the sponge X.testudinaria, which is a sponge from the petrosiidae family. Various studies have shown that the X.testudinaria sponge obtained from various waters in the world contains secondary metabolites with certain bioactivity, including as an antiviral. Research related to the study of dengue antiviral bioactivity from sponge X.testudinaria from the waters of the Spermonde Islands was carried out through an extraction process carried out in stages using chloroform, ethyl acetate, methanolin sequence, then determining the cytotoxic effect ton Verocells and determining theactivity of dengue antiviral of each extract.The results showed tha tthe ethylacetate and methanol extracts had a strong cytotoxic effect against verocells (CC50 21 µg/mL and 26.65 µg/mL) and that chloroform extrac twas less toxic to verocells (CC50 244.98 µg/mL). Chloroform and methanol extract respectively showed very strong inhibitory activity against dengue virus with low IC50 values (0.27 µg/mL, and 0.313 µg/ mL),where asethylacetate extract had a low inhibitory effect (IC50107.76µg/mL). The SI value of chloroform the extract was the largest (SI = 903.7), which means that chloroform extract is more selective and most appropriate to be used as a dengue antiviral drug compared to ethylacetate and methanol extracts (SI: 0.329 and 85.14).

One of the factors that determine the effectiveness of an alcohol esterification reaction is the group attached to the acyl chain. The study of the esterification reaction of menthol with acetic acid and its derivatives has been carried out with success. The esterification reaction of menthol was carried out with glacial acetic acid, acetic anhydride, and acetyl chloride. The effectiveness of esterification, both from the yield and the resulting content of menthyl acetate, shows that acetyl chloride is best effective, followed by acetic anhydride and acetic acid in its esterification against menthol.
