Published: January 2022

AbstractTrees have a vital role in human life, including as a part of the urban forest area. The tree health assessment is an important activity to support tree safety and stability in an urban forest. Bogor Botanic Garden is the most extensive botanic garden in Indonesia, with a large collection. The study aims to determine the health condition of old trees (Pterocarpus indicusWilld.) in the Bogor Botanic Gardens and measure the safety factor’s magnitude. The method used was an evaluation generated based on a sound velocity from Arborsonic’s tool. The measurement of appearance parameters was carried out to complete the information in determining the biomechanical strength of the tree. Four large and old trees, about 170 years old, were chosen in this study. The results showed that decay to hollowness in the trunk varied from 4% to 58%. The biomechanical analysis calculates the safety factor and t/R ratio, revealing that one tree had moderate risk and others possessed low risk. Further investigation to ensure the tree condition should be carried in terms of risk mitigation of tree management.

Abstract
Settlements are indispensable to humans as a place of residence and for other activities. Moreover, there is an increase in land requirements for settlement construction due to the high population. The development of cities and settlements in the context of SDGs needs consideration to mitigate, adapt to climate change, and resist disasters. Therefore, this study aims to identify, analyze, and describe disaster mitigation-based land suitability and availability for settlements in the Northern Part of South Barito Regency. The method used was Multi-Criteria Evaluation (MCE), while the inclusion criteria are slope, soil type, rocks, drainage, soil texture, elevation, land use, and distance to the rivers. Each criterion was weighted using an AHP, while scoring and map overlaying were carried out using a GIS to determine the class of land suitability. The flood hazard map was used to obtain the area of free flooding. The results showed that actual land suitability for the most extensive settlements is in the S2 (Moderately Suitable) class. Meanwhile, the land that is used without flood hazards is approximately 18.9% of the Northern Part of South Barito Regency landmass. This analysis is used as consideration by policymakers to develop spatial planning in South Barito Regency.

Abstract
In order to maintain the reliability and durability of the internal combustion engine during the operation of machines, systematic and operational monitoring of the state and level of technical fluids is necessary, where the most informative indicator is the change in the state of motor oils. The drop test method has been used for express diagnostics of motor oil for many years. Grades of oils with high base number, which are mainly used for high-speed internal combustion engines when diagnosing the state of these oils using the drop test on the surface of the filter used for analysis (Blue Tape filter paper), do not form zones in the form of rings, the change in diameter of which allows evaluating the operational properties of the operating motor oil. The study established that when analyzing the preservation of the properties of strongly alkaline motor oils (assessment of the contamination coefficient, dispersing properties), a spot of dirty oil is formed on the chromotogram of filter paper thus showing the filter structure. Theoretical studies revealed that the segregation into zones during the analysis of motor oils with strongly base number does not occur due to the action of electrical forces leading to the repulsion of contaminant particles. Electrical forces arise due to changes in molecules and alkali when a drop of oil flows through the surface of the filter, this interaction continues, and therefore, to analyze strongly alkaline motor oils, the base number must be neutralized, and a correction factor for the neutralizer must be introduced. The paper presents the results of experimental studies to determine the effective neutralizer of the alkalinity of a working motor oil in the process of diagnosing oil by the drop test, which made it possible to obtain concentric zones on the surface of filter paper to calculate the dispersing ability and other estimated oil indicators.

Abstract
The purpose of the study was the laboratory testing of the pendant seeder-spreader “G-1” (production of China) as part of the universal unmanned aircraft system “OSA HEXA” based on UAV “OSA” (the developer and producer was Bozon LLC, Moscow). The tests were carried out on December 18-19, 2018 in a closed hangar with a total area of 9500 m2 and a height of 15 m, in accordance with the “Program and Test Methodology for Spreading Device Based on the UAV ”OSA””, developed by the AgroEcology laboratory in collaboration with Bozon LLC. In the testing process numerous design weaknesses of the seeder-spreader were identified, based on which it was concluded that the pendant agricultural equipment was unsuitable for fieldwork in the conditions of Russia. The R&D department of Boson LLC was recommended to carry out a deep modernization of the seeder-spreader in order to eliminate the identified design weaknesses. The results obtained are recorded in the following documents: “Act No.1 of testing the spreading device based on UAV “OSA”” and “Protocol No. 1 of laboratory testing of pendant equipment of UAS ”OSA“”. Bozon LLC took into account the identified design weaknesses and recommendations and developed and mastered in 2019 the production of the seeder-spreader “S-Γ, which could be installed on the hexacopter “OSA HEXA”, designed for automatic sowing of small seeds or spreading solids on arable fields, forest land and fishery basins.

Abstract
In recent years, periodic droughts in various regions set limits to the production of field crops, negatively affect the economy of land users and the condition of soil. In this regard, the relevance of research on the development of options for energy-saving technologies that contribute to the preservation of productive moisture, yield of field crops and the return on production costs and maintaining soil fertility is increasing. The research on this issue had been carried out in the central zone of the Krasnodar Territory in 2013-2018. The researchers studied the effect of 22-24cm plowing (the control); surface 6-8 cm and zero direct sowing technology for oil flax, winter wheat, stubble sowing without irrigation and sowing peas, as well as their combined effect on the economic efficiency of production and the dynamics of organic matter in ordinary black soil. It was found that the cultivation of 4 crops for 3 agricultural years for basic surface tillage exceeded the control for the conditional net income and the formation of organic matter - humus over its consumption. The technology of direct sowing of crops provides a conditional net profit and dominates over moldboard plowing and even surface tillage in terms of the accumulation of organic matter in the soil. The studied combination of crops, with different biological characteristics, and energy-saving technologies for their cultivation allows maintaining profitable agricultural production and soil organic matter in the present period and in the future.

Abstract
The paper deals with the issues of corn production and agricultural machinery used for this. It is noted that the ridge technology has the best environmental properties among the corn cultivation processes. The paper provides information about the main agro-engineering requirements when using this technology, its advantages and machines used for soil cultivation and sowing corn seeds. Particular attention is paid to the technological issues of harvesting corn for grain and engineering support of production processes, such as use of both dedicated corn harvesters and combine harvesters fitted with the necessary equipment including special corn attachments and reapers. Depending on the availability of technical equipment in agricultural enterprises, the ripeness and moisture content of the grain and other factors, a certain corn harvesting process is selected to obtain peeled cobs, unpeeled cobs or a grain and corncob mixture. The use of dedicated corn harvesters ensures obtaining peeled cobs. Harvesting when obtaining unpeeled cobs allows reducing grain losses, as well as labor and cost, and increasing the amount of corn leaf and stalk mass harvested. Both domestic harvesters and reapers, and those produced by foreign companies are used. This takes into account the manufacturability of the equipment, the possibility of maintenance, and economic factors.

Published: January 2022

Abstract
During the 20th and first quarter of the 21st century, there have been not only significant quantitative, but also structural changes in grain production close to some central applications of grain: food consumption, fodder consumption, industrial consumption, provision of seed production, foreign trade. Strategic planning of grain production in the country depends on many factors, including changes in grain production and processing technologies, widespread and accelerated integration of selective breeding results, multifactorial modeling of animal diets. The volume of consumption and the structure of cereals in the total volume of production is impacted by such processes as population growth, urbanization and changes in dietary preferences of modern people. One of the most important tasks in the development of the farming industry is to assess some possible prospects for the development of grain growing, with due account for new priorities to come up in the use of the entire biodiversity of cereals. Benchmark analysis of the ratio between the volumes of production, consumption and export-import of grain, rationale for the optimal characteristics of the grain-growing sector of the national economy, as an essential element of strategic potential, represent one of the fundamental interdisciplinary challenges facing modern science.
