Abstract
Soil-forming rocks of the tertiary period are widespread, most of which have a clay composition, are highly compacted and cause more extreme regimes, which cannot but affect biological conditions and, in total, soil formation and fertility. In this research, all experiment were carried out in the study area in Chirchik-Keles in Tashkent region. The results showed that depending on the parent rock, the degree of erosion, soil composition, and the density of the solid phase of soils varied from 2.60 up to 2.72 g/cm3 and is 2.59-2.61 g/cm3 in the upper humus horizons, and 2.67-2.72 g/cm3 in the lower ones. Moreover, for soils on Tertiary deposits, the values were somewhat higher, which can be explained by the peculiarities of the mineralogical composition.

Abstract
Gossypol is secondary metabolite that play diverse role in plant adaptation to environment. Obtained from cottonseeds gossypol has valuable biological properties and forms an abundant number of clathrates with a large variety of compounds. One of the primary reasons why gossypol can form clathrates is its ability to organize extensive hydrogen bonding networks due to its hydroxyl and aldehyde functional groups. Less hundred clathrates as single crystals have been obtained and their crystallographic parameters have been determined. Solutions were prepared by adding 0.5 g of gossypol and 6.0 ml (6.3 g) of acetic acid, 4.0 ml (3 g) of acetone, 5.0 ml (4.5 g) of ethyl acetate, 2 ml (2.0 g) of 1,4-dioxane, 9.0 ml (13.4 g) of chloroform, 11.0 ml (9.6 g) of benzene to six small glasses vials at room temperature. The structures of 30 inclusion complexes have been solved by diffraction methods. This natural polyphenol forms stable clathrates with acetic acid, acetone, ethyl acetate, 1,4-dioxane, chloroform and benzene. This work describes investigation of gossypol clathrates by single-crystal diffraction and thermal analysis.

Abstract
This article establishes a number of requirements for cotton fiber processing enterprises to improve production efficiency and rational use of resources and maintain high rates of natural quality of cotton fiber during processing. In addition, as a result of the research, it was found that changing the impact pressure of the scraper brush, creating a new shape of the scraper device, changing the relative position of the grate and the scraper brush, placing an additional scraper device after the scraper brush, so as not to be part of the dirty mixture that separates the piece of cotton, were found some positive results. The proposed design of the cotton cleaning section of the UXK purifier, due to the above features, makes it possible to increase the cleaning effect compared to the existing purifier, since in the proposed version, the process of cleaning cotton from large impurities is carried out twice in each section of the USC, which cleans cotton from large impurities. The proposed technical solution was taken as a basis and a plan was developed for preparing its structural diagrams and working drawings, manufacturing a laboratory stand for the cleaning section, conducting laboratory experiments with it, substantiating the main parameters of the working bodies according to the proposed scheme, and introducing the proposal into production.

Published: March 2023

AbstractThe hybrids of medium-fiber cotton were assessed in terms of fiber quality in the Tashkent, Fergana and Kashkadarya regions of the Republic of Uzbekistan. 4 hybrid combinations of different genetic origin were tested. The analysis of the influence of the genotype and the environment on the manifestation of the qualitative parameters of the fiber (length, specific breaking load, micronaire) was carried out. High values were found in hybrids involving the wild speciesG. trilobumSkovsted and the ruderal formG. HarknessiiBrand. as well as varieties Bukhara-6. As a result of three years of experiments, it was found that the genotype and unaccounted factors influence the variability of the fiber length to a greater extent. The genotype rather than the environment significantly affects the specific breaking load of the fiber. The variability of the micronaire fiber is more dependent on environmental conditions.

Abstract
One of the important problems in cotton breeding is the creation of high-yielding, fast-maturing varieties with high fiber yield and quality and their wide use in production. Due to the increase in the number of people on earth and the reduction of irrigated arable land, it is important to get a high quality harvest suitable for different soil and climate regions without expanding the arable land. This research intended to study the variability of the observed characters in the phenotype of the cotton plant during the selection of four F2-F4 hybrid combinations in the conditions of Tashkent, Fergana and Kashkadarya regions. During the research experiments, classical genetic-selection methods of cotton, hybridological analysis methods, comparative morphology, phenological observations and genetic-statistical analysis methods were used. The results showed that the average indicators of this sign were approximately the same in Fergana and Kashkadarya regions, accounted for 116.5 and 117 days, which was 12 days shorter than the growth period of this hybrid in Tashkent region. Similarly, insignificant changes of the above combinations were also observed in the experiments of 2019 and 2020. It was found that in F2 [(F8 L-247 x S-484) x F15 L-248], the fiber length variation was not significantly affected by the environment, the variation ranged from 0.04 inches to 0.07 inches.

AbstractIn the pasca of the COVID-19 pandemic, many researchers have focused on finding drugs for the COVID-19. Peptide research is predicted to have a physiological mechanism of action and it does not cause side effects, therefore it is necessary to search for peptide sources. The aim of this study was to characterize peptides extracted from tamban fish (Sardinella fimbriata) and fermented products (Cincalok of Tanjungpinang). Peptide extract was obtained by maceration extraction using 95% PA (1:5) ethanol solvent, and then it filtered using MWCO 3 kDa and 10 kDa. The amino acid characteristics of the peptides was obtained using HPLC. Peptides of tamban fish had the pH of 7.6 and they are rich of amino acid histidine (890.18 mg/L), in addition to the amino acids glutamate, tyrosine, glycine, leucine, alanine, and aspartic acid. But the peptides of the fermented cincalok product had the pH of 6.4 and they are rich of amino acid leucine (1066.83 mg/L), in addition to the amino acids glutamate, valine, isoleucine, and alanine. Each of these peptides had the molecular weight of 10 kDa. The results of this study can be used as preliminary information to the pharmaceutical development of a new source of peptides.

Published: March 2023

Abstract
Red Mud is a bauxite solid waste which is dangerous for the environment because of its alkalinity (10-13). With a very high pH, it can interfere with the hydrological conditions of areas that are directly affected by Red mud. Efforts to utilize red mud to have use-value have been widely carried out. Red mud consists of Gibbsite, Hematite and Cristobalite. The main ingredients of red mud are Fe2O3, Al2O3, and SiO2 which can still be utilized by 44.66%, 28.87% and 20.21%. Red mud can be utilized as a basic material for bricks. Red mud needs to be composited with other materials because it does not have enough SiO2 composition to get good quality bricks. For this reason, in this study, Red mud was composed of clay and coconut fiber. Both of these materials are known to have high SiO2 content compared to Red mud. In this study, the optimal composition of red mud, clay, and coconut fiber ash compositions was 3: 3: 1.

Abstract

Rhizopora sp has a single root. The shape of the roots, which are like anchors, is what makes mangroves a wave absorber, sediment binder, and so on. One of the functions of mangrove roots is to prevent the release of garbage into the open sea. This is due to the shape of the roots that make garbage snagged (caught) on the sidelines of the roots. The purpose of this study was to analyze the capture of marine debris in the mangrove roots of Rhizopora sp in the Sengarang Besar ecosystem. This research was conducted in December 2021 in the mangrove forest of Senggarang Besar. The method used is the line transect method with 10 Rhizopora sp mangrove trees located on the coast. Then, data analysis on the density of waste caught in the mangrove roots of Rhizopora sp. The results showed that the inorganic waste found in the mangrove roots of Rhizopora sp were plastic waste, metal waste, glass waste, rubber waste, and cloth waste. Plastic waste is the highest waste catch in the mangrove ecosystem of the Great Senggarang beach. Then the data that has been taken is analyzed using Pearson correlation to prove whether there is a relationship between the circumference and the type of garbage caught. The results of the Pearson correlation between cloth and plastic with root circumference were -0.30 and -0.04 (no correlation between the two variables); Pearson glass correlation with root circumference was 0.45 (sufficient correlation); Pearson rubber correlation with circumference is 0.71 (strong correlation). It can be concluded that there are other factors such as geographical influences, ocean currents and others in the catch of garbage at mangrove roots.

Published: March 2023

AbstractAgriculture is one of top best-selling non-oil-and-gas products. However, environmental-related purposes for production, based on the Regulation of Forestry Ministry of Republic of Indonesia No P50/Menhut-II/2010 for the Right to Exploit, not meet the Ecosystem Reforestation Rights. Land degradation means loss of the productive capacity of the soils that has huge risk to food insecurity, loss of ecosystem biodiversity and climate change. In Tapin, one of the most productive agriculture in South Kalimantan Province, dramatic decline in the productivity of croplands can be one of the most important contributors of climate change. The action of Land Degradation Neutrality (LDN) by adapting innovation has been a solution of reducing vulnerability and increase climate change resilience to combat rising demands for agriculture product and the agricultural production system. Smallholder farmers and rural community need to intensify the production of food for sustainable agriculture and food security, as mentioned in Sustainable Develompent Goals (SDGs) Goals 15.

Abstract
Ciletuh is an areas in Sukabumi which was inaugurated as Global Geopark by UNESCO in 2017, and has many potential natural resources. The high number of visits at Palangpang Beach, Ciwaru Village, is an opportunity for fishermen in Ciwaru Village to participate in activities involving fishermen in the marine tourism sector but this is inversely proportional to the infrastructure development at the Ciletuh Geopark. So, it is important to analyze sustainable livelihood of fishermen before and after the development of the Ciletuh Geopark. The research methods used are descriptive analysis, and sustainable livelihood analysis. The results show that sustainable livelihood assets of fishermen who increasing were human capital, social capital, physical capital, and economic and financial capital, while natural capital experienced a decline in assets due to the accumulation of garbage on the shore and in the sea that interferes with fishing activities. Finally, The local government and the management of Auction Place of Fish of Ciwaru have made improvements to fishery support facilities, in the form of parking lots for fishing boats and more adequate fish landings for fishermen, but the government needs to manage the garbage on the beach area.

Published: March 2023

Abstract
With the increasing use of high-frequency electronic and wireless devices, electromagnetic interference (EMI) has become a growing concern due to its potential impact on both electronic devices and human health. In this study, we demonstrated the performance of lightweight, electrically conducting 3D resorcinol-formaldehyde carbon xerogels, of 2.4 mm thickness, as an EMI shieldin the frequency range of 10–15 GHz (X-Ku band). The brittle carbon xerogels revealed complex porous structures with irregularly shaped pores that were randomly distributed. Electrochemical characterization revealed that the material behaved as an electrical double-layer capacitor. The carbon xerogels displayed reflection-dominated (∼ 84%) shielding behavior, with a total EMI shielding effectiveness (SE) value of ∼ 61 dB. The absorption process also contributed (∼ 16%) to the total SE. This behavior is attributed to the carbon xerogels' complex porous network, which effectively suppresses EM waves.
