Abstract
Several countries are experiencing economic instability due to the crisis caused by the COVID-19 pandemic, not least Indonesia. This research aims to identify priority aspects that affect the resilience of entrepreneurship in the tourism sector. This research was conducted in the Togean Islands of Tojo Una-Una Regency by interviewing several stakeholders as many as 30 people consisting of business actors. The analysis method used in this study is the analytical hierarchy process (AHP). The results in this study showed that social justice criteria were very prominently chosen by respondents compared to other criteria. This shows the social sensitivity possessed by entrepreneurs during the Covid 19 pandemic. This research requires justification in future research to be used as a generalization in terms of entrepreneurial resilience theory in the face of pandemic risk as it is today.

Published: December 2022

Abstract
The article notes that when plowing, the traction resistance of a ploughshare with an occipital chamfer increases in proportion to the volume of compacted soil. When working, the traction resistance of the ploughshare with the occipital chamfer increases in proportion to the volume of the compacted soil. It was revealed that with an increase in the angle of the occipital chamfer of 5 to 40 degrees, the traction resistance increases 11.3 times, Whereas with an increase in the width of the occipital chamfer from 0.5 mm to 4 mm, the traction resistance increases 60...64 times. For the longest operation of the ploughshare, it is necessary to develop such a technical solution for the ploughshare, during the operation of which an occipital chamfer with the largest dimensions, that is, with a minimum area, was formed from the back side. Then the pushing force of the ploughshare from the soil will have a minimum value, which will ensure the operation of the plough for the most maximum time without violating agrotechnical requirements for the depth of processing.

AbstractThe paper considers the theoretical and practical aspects of the relationship between the processes of sea ice melting and methane migration, and their influence on the distribution of chlorophyll-aconcentration as an indicator of productivity and the level of quantitative development of the phytoplankton community at the spring stage of the succession cycle. In the spring of 2018 and 2019 the thermohaline characteristics of waters and the content of chlorophyll-ain the Barents Sea were studied. The area of work covered both areas with the most probable release of methane from near-bottom gas hydrates, as well as background areas, where the presence of methane hydrates is unlikely. In 2018, the phytoplankton community of the study area was in the spring flowering stage. In the area of the most probable influence of methane, the average concentrations of chlorophyll-awere approximately 2 times higher than in the background area. High concentrations of the pigment were associated with the thawed layer, which may indicate the release of methane from the ice. In 2019, low concentrations of chlorophyll-ain the edge zone excluded the stage of spring flowering of the phytoplankton community, which did not allow us to trace the possible effect of the release of methane hydrates on the concentration of chlorophyll-a.

Abstract
The seed shell of soybeans performs a protective function and participates in the vital processes of the seed. Soybean seeds are characterized by a unique chemical composition. The priority direction in the development of technologies for the production of foodstuffs from soybeans is the control of the quality indicators of their seeds shells. The use of a spectrofluorimeter and an IR-Fourier spectrometer allows you to study the coating material of soybean quickly and without destruction. For the purposes of comparative spectral characterization, studies were carried out on the soybean seed envelope of the untreated and treated modifier mixture. Main characteristics of luminescence excitation spectrum are determined including recording wavelength, excitation spectrum region, excitation wavelength intensity. Parameters glow attenuation are revealed by spectral-kinetic studies of phosphorescence of soybean seeds shell. IR spectroscopic analysis of milled and whole soybean seeds, as well as modifiers, allows us to interpret groupings that have characteristic oscillation frequencies. The main spectral characteristics of the soybean seed shell are determined, including wave numbers, incident radiation wavelength, transmission, and oscillation character. Modifiers adsorbed on surface of soybean seed shell are identified. The type of adsorption of the modifier shell is defined.
Climatic features of the use of special elastomers with high heat resistance in agricultural machinery
Authors: Golikov V A 
Published: December 2022

AbstractIn agriculture and the production of agricultural machinery there is a great demand for materials with high resistance to temperature effects. A special place is occupied by seals, because the characteristics of power units, their reliability, and the possibility of using them in certain conditions largely depend on their quality. The heat resistance of elastomers used as sealants in agricultural machinery is the ability to maintain performance to ensure sealing of joints when exposed to high temperatures for a long time. Heating initiates accelerated thermal aging, which causes a few polymer-destroying processes, while the most important material indicators, such as elasticity, strength, wear resistance, etc., change for the worse. The possibility of operating rubber seals at elevated temperatures is mainly determined by the composition and structure of the polymer.

Analysis of the process of cutting the stem with a knife of a disk chopping apparatus
Authors: Jumatov Y 
Published: December 2022

Abstract
The paper presents the results of the analysis of the process of cutting the stem with a disk-shaped knife, taking into account the physical and mechanical properties of stalk feed. The shell of corn stalks grown in the hot climate of our country is thicker and harder, and its coefficient of friction is somewhat lower. The smaller the angle of friction, the more difficult it is to clamp such a rigid piece of rod between the active and fixed blades. To avoid this condition, the stem must be pinched and sheared between the active blade and the passive blade. On the basis of kinematic studies, the conditions for ensuring the sliding of the rod along the blade of the grinding knife are determined in the work. Based on the physical and mechanical properties of corn stalks, the conditions for ensuring the sliding movement of the stalk along the chopper knife blade are considered.

Abstract
Wheat varieties were used as objects of research: Novosibirskaya 29, Uyarochka - mid-early, Krasnoyarskaya 12, Kuraginskaya 2 - mid-ripening, Svirel - mid-late. Sowing dates are May 17 and May 25. The duration of the growing season of spring wheat varieties was determined to a greater extent by the number of days of the germination-earing phase. At different sowing dates, the mid-early varieties Uyarochka and Novosibirskaya 29 formed the same duration of germination-heading periods (52-54 days); in the varieties Kuraginskaya 2 and Krasnoyarskaya 12, this period decreased by two days at the late sowing time, and significantly reduced in the variety Svirel (by 6 days). In general, the duration of the growing season with a late sowing period decreased by 2-6 days, while the growing season of mid-ripening and mid- late varieties is longer than medium-early ones by 8-14 days. Mid-early varieties Novosibirskaya 29 and Uyarochka formed a yield of 3.02-3.32 t/ha, regardless of the sowing date. Varieties of spring wheat of the middle and middle late types Kuraginskaya 2, Krasnoyarskaya 12, Svirel significantly increased yields at the optimal sowing time: by 0.31 t/ha, 0.32 t/ha and 0.53 t/ha, respectively. Mid-ripening and mid-late varieties exceeded early-ripening biotypes in terms of yield at both sowing dates, providing an increase of 1.3 to 1.5 t/ha. The recommended sowing time for wheat Svirel, Kuraginskaya, Krasnoyarskaya May 12 - 17, for mid-early varieties - Uyarochka, Novosibirskaya May 29 - 27.

Published: December 2022

Abstract
In the modern world, both in the Russian Federation and abroad, the unresolved problem of complex and rational processing of low-fat dairy raw materials, in particular whey, is still acute, despite active research in this area. Another problem, no less important and relevant, is poor-quality nutrition of the planet’s population, which leads to an increase in the number of alimentary-dependent pathologies, in connection with which there is a need to enrich food products. A dessert with milk whey, which has an increased nutritional value due to the introduction of vegetable food flavoring components, is proposed for production and research. The product is designed for preventive nutrition, it is possible to consume in the presence of a common disease - diabetes, which is due to the presence of natural sugars and the introduction of stevia sweetener with lactulose. Studies have been carried out to determine organoleptic, physicochemical and rheological indicators.

Study of cellulose extraction and cavitation from plant raw materials
Authors: Usenov A B , Samandarov D I , Alimova D K , Saparov Dj E , Sultanov Sh A 
Published: December 2022

Abstract
In this paper cavitation in extraction is studied. It occurs as a result of a decrease in pressure in a fast-flowing fluid to a certain critical value (hydrodynamic cavitation) or as a result of the passage of acoustic waves in the fluid (acoustic cavitation). The gas and vapor bubbles in the liquid increase infinitely and turn into large “cavitation bubbles”. The bubbles are formed by the dissolution of a gas in a liquid and decrease and disappear when the pressure reaches the critical pressure area. As a result, a “cavitation zone” is formed near the body through which the fluid circulates. At the boundary of the zone, the bubbles decrease very rapidly and a hydraulic shock occurs. The combination of such shocks results in a rumbling sound that is always accompanied by cavitation

Abstract
Fusarium wilt (Fusarium oxysporum f.sp. cepae) is the most important soil-borne disease in garlic. This pathogen is a weak parasite so that it can be controlled through healthy plant cultivation approaches such as the use of organic compost fertilizer and soil microbes as biological control agents. Gliocladium sp. is an antagonist fungus that can be used as a soil borne disease control agent. This study aims to evaluate the effectiveness of compost plus Gliocladium to control garlic root rot in endemic land. The experiment was carried out in Tawangmangu Karanganyar at 1000 meters asl. The experiment consisted of 5 treatments arranged by completely randomized design with three replications. The main variables are disease incidence of fusarium wilt and control efficacy. The other variables observed were the fresh and dry weight of the biomass and the yield in the form of the weight of garlic bulbs per plant. Data processing carried out was analysis of variance and DMRT at 5% level. The results showed that compost plus Gliocladium produced higher effectiveness than compost alone or Gliocladium alone. The effectiveness of compost plus Gliocladium was more effective in suppressing fusarium wilt compared to farmers using fungicides and artificial chemical fertilizers.

Published: December 2022

Abstract
This research measures the lead, cadmium, copper, nickel, chromium, and arsenic in the paddy fields in Nganjuk Regency. Moreover, this research identifies the effect of these metals to the environment and their location. 105 topsoil samples were collected. The AAS was utilized to ascertain the elemental composition of the soil samples. Numerous soil pollution and ecological risk indices, such as Igeo, PI, IPI, PLI, and PERI, were used to analyze the situation. Spline interpolation with ArcGIS 10.2 was used to study metal distribution. The metal content (mg/kg) in Pb, Cd, Co, Ni, Cr, and As was 10.01, 0.77, 9.60, 5.46, 3.61, and 2.79, respectively. These pollutants had pollution index values of between 0.59 and 2.56 and 0.05 and 0.56 on the lower end of the scale. With an average of 1.10−6, the pollutant load index suggests that all samples are safe. The paddy fields in the research region have an average PERI score of 91.48, indicating a low ecological risk. Most metals researched under agriculturally safe levels will be highly valuable for establishing control and remediation measures in paddy fields.

Abstract
The productivity and price of hybrid corn in Karanganyar Regency are lower than the productivity and price of the surrounding districts, especially during the la Nina storm. This study aims to determine the feasibility of mixed corn farming in the Karanganyar Regency. Determining the location and sampling was done using the purposive sampling technique with 80 farmers as respondents. The data analysis method used was the farm Cost-income analysis, R/C ratio, BEP (Break-Even Point), Profitability-cost ratio, Labor productivity, and Sensitivity analysis. The average income was IDR 3,975,741 per farm or IDR 7,795,571 per hectare. The average cost calculated was IDR 1,930,362 per farm and 4,257,302 per hectare. The analysis of BEP, R/C ratio, the profitability-cost proportion, labour productivity and sensitivity showed that hybrid corn is feasiblethe profitability-cost proportion was more significant than the applicable bank interest. Labour productivity was greater than the prevailing labor wage. The sensitivity showed that hybrid corn farming was feasible under decreasing prices by up to 50%. Therefore, farmers still benefit from cultivating hybrid corn. However, the effect of La Nina will continue, so farmers must be more adaptive to excessive water and pest attacks on their land.
