A Review of Contact Models’ Properties for Discrete Element Simulation in Agricultural Engineering

In agricultural engineering, the discrete element simulation of the operational structure, object of movement, and force has become a standard method of modern agricultural equipment design. The selection and development of an appropriate contact model are critical factors affecting the accuracy of the process of the simulation calculation of the movement and force. Understanding how to choose or establish suitable contact models according to different research fields, objects, and purposes has become the focus of present research. This paper gives an overview of contact models for discrete element simulation, summarizes and analyzes the simulation calculation basis of different contact models, and focuses on the application status and scenarios of different models at this stage. It analyzes and summarizes the selection basis and application fields of contact models. The next direction in the development of discrete element simulation contact models should be the hybrid application of multicontact models and the precise development of specialized contact models. It is necessary to establish a standardized parameter-calibration process for different contact models to guarantee the accuracy of the models, to improve the application of computer arithmetic, and to establish an efficient and accurate simulation contact model selection and application in the field of agricultural engineering. Efficient and accurate simulation contact model selection, design theory, and calculation processes will improve the efficiency of modern agricultural machinery design.

PENINGKATAN HASIL PERTANIAN KELOMPOK WANITA TANI DI DESA LUMBAN TOBING KAB. HUMBANG HASUNDUTAN

The current conditions are that partners still use conventional methods in processing land, namely using hoes and rakes, while the land that must be cultivated is 17,800 m2 – 22,600 m2 / person. If you use manual methods, what happens is that a lot of land cannot be cultivated optimally, so that the productivity of agricultural products is not optimal. The purpose of using a cultivator in tillage is to create a physical condition of the soil that is suitable for plant growth with equipment that works mechanically and on a large scale. Modern agricultural equipment plays a very important role in supporting agricultural operations. Currently, almost all farmers in Indonesia have switched to using machines rather than livestock, such as buffalo and cows, to plow their fields. The reason is, modern rice cultivators can be operated on various agricultural land, ranging from dry (fields) or wet (rice fields). so that the results obtained are increasing partners' skills in using agricultural technology, both in the form of use and maintenance of these tools.Cultivate agricultural land more optimally so that the productivity of agricultural products is maximized. Partners' problems regarding human resources are resolved through the provision of 1 cultivator unit

Institutional Synergy in Diffusion and Adoption of Agricultural Technology in Farming Communities in Bantul District, Daerah Istimewa Yogyakarta

The process of diffusion and adoption of agricultural technology can be realized properly if it is supported by the synergy of agricultural institutions and from farming actors. The existence of farmer groups and farmer cooperatives as part of agricultural institutions that are under one roof, is an important forum for farmers in overcoming various problems. The aims of the research were to find out the synergy between agricultural institutions in the diffusion of agricultural technology in farming communities in Bantul Regency, DIY and to find out the level of adoption of agricultural technology by farming communities in Bantul Regency, DIY. The research method was carried out in a descriptive qualitative manner. Data was collected by interviewing cooperative management, farmer groups and farmers with the help of a questionnaire.

From the research results it is known that the diffusion of agricultural technological innovations is carried out in synergy and in stages from the government through the Ministry of Agriculture, the agricultural service, Bank Indonesia, universities, PPL to the management of farmer groups to be disseminated to members. Farmers' cooperatives function as providers of capital, infrastructure such as seeds, subsidized and non-subsidized fertilizers, pesticides and medicines. Meanwhile, farmer groups function as providers of labor and modern agricultural equipment. The level of farmer adoption of agricultural technological innovations is in the good category with a score of 78.

The use of differentials to increase the efficiency of orienting robotic devices of agricultural equipment

Robots are used in modern agricultural equipment. There are several types of robot designs: articulated robots, delta robots, sсara robots and others. Almost every robot has in its design an orienting device, designed to orient the tool, used by the robot in space. Orienting devices differ from each other by different structural diagrams of transmission mechanisms and types of links, functioning in the mechanisms. All orienting devices are united by a design feature, which consists in the fact, that in order to rotate the tool around the axis of any kinematic pair, which is the degree of mobility of the orienting device, it is necessary to rotate several electric drives. If you rotate with one electric drive, the tool will make a spherical movement. The reason for this effect is that the kinematic chains, through which rotation is transmitted from the electric drive to the tool, intersect with each other. The use of differentials in the design will allow the tool to rotate around one axis by one electric drive, which gives some advantages in motion control. The article describes the design features and the principle of operation of the orienting device with differentials.

Controlling Sunflower (Helianthus annuus L.) Fertility with Bio-Nutrition

To investigate the effects of certain plant extracts and seaweed on the yield and quality of three sunflower cultivars, as well as their fertility rate. A field experiment was carried out in the Al-Yousifiyah region - Al-Rasheed district, during the spring season of 2022, in one of the fields dominated by the Dabbana Modern Agricultural Equipment factors. A randomized complete block design (RCBD) was utilized in a split-plot with three replications. The main plots included five nutrition treatments (spraying BMstart biostimulants, spraying Alga600 seaweed extract, adding Seek (bamboo plant residue), and spraying Moringa leaf extract, with water as the control treatment), and the sub – plot included three cultivars (Lilo, Ishaqi-2, and Flamy). The results demonstrated the superiority of Alga600 seaweed extract with a weight of 1000 seeds (103.78 g) and the number of seeds per head (2162.73 seeds head−1). Whereas the Moringa leaf extract was superior in terms of head diameter (28.48 cm), fertility rate (96.410%), seed yield (4.980 tons h−1) and oil percentage (45.61%). The Ishaqi-2 cultivar exhibited the highest seed production (5.222 tons h−1), however the Flamy cultivar revealed the highest fertility (96.63%) and oil percentage (43.20%), consequently. we advocate planting the Ishaqi-2 cultivar and implementing moringa leaf extract to boost output by 17%.

Multipurpose Attachment System for Ploughing, Spraying and Creating Ridges in Agriculture

Small-scale farmers would be benefited from versatile attachments that may be used to automate chores that would typically need both human and animal efforts in terms of cost and labor. Farming is made simpler and faster by mechanization. For practically every task in agriculture, there is a machine accessible. Various machines are used to do all the steps right from preparing the soil to crop harvesting and beyond, thus making chores not only easier to complete but also do them effectively. Modern agricultural equipment is more expensive and out of the reach of the majority of farmers with little resources. Due to their low-income levels, most farmers are unable to invest in the purchase of significant machinery. Given the aforementioned circumstances, it is necessary to create a piece of machinery that can be used for a variety of tasks, including ploughing, creating ridges, and Spraying. In order to address this issue the present paper reports the fabrication of a novel machine with multifunctional attachments to carry out above mentioned tasks efficiently and economically.

Productivity Of Grain Crops In The Conditions Of The Training And Experimental Field Of Orenburg State Agricultural University

The relevance of the topic of scientific research is associated with the biological characteristics of the studied grain crops in specific natural and climatic conditions. The purpose of this work was to identify the potential capabilities of various grain crops in terms of yield and quality indicators of grain in the central zone of the Orenburg region. Food security of the population in the overwhelming majority of countries is most often associated with the provision of grain. At present, despite the active introduction of modern agricultural equipment and innovative technologies into the world agricultural production, it is not possible to achieve a significant increase in gross grain harvests. The level of its production is still insufficient to fully meet the growing needs of the rapidly growing population. According to the expert assessment of domestic scientists, in the conditions of modern natural and anthropogenic changes in the environment, Russia can play an important role in stabilizing the world grain production, which has sufficiently high natural, intellectual and technical resources for this. Their effective and rational use on the basis of nature-like, ecologically-oriented agricultural technologies can make a significant contribution to increasing food stability. Meeting the needs of cultivated plants in the elements of mineral nutrition was reduced mainly to the mobilization of soil fertility, i.e. depletion of humus reserves. As a result, in most of the grain-sowing regions of Russia, and primarily in the regions of the steppe zone, its negative balance has developed. It is quite obvious that these circumstances are a serious obstacle to sustainable grain production and can lead to even greater degradation of disturbed soils, disruption of the biological balance in agroecosystems and a reduction in biological diversity.

Assessment of reproduction of agricultural products

To expand the reproduction in the agricultural industry (a priority task of Russia), to achieve the goal of import substitution and food security, it is necessary to ensure continuous renewal and replenishment of resources. To assess the type of reproduction in agricultural organizations, average annual growth indicators taking into account resource (labour, land, capital) and economic conditions (profitability, liquidity, financial stability, turnover) were used. According to the method used for assessing the type of reproduction, organizations can be categorized into three clusters. Development problems within each cluster were determined to evaluate conditions of reproduction taking into account cluster characteristics. Agricultural organizations using the method of expanded reproduction have modern agricultural equipment, high-yielding crop varieties and highly productive animal breeds. Organizations of the second and third clusters have limited resources (labour, land, basic and working capital) and low profits.

Russian Market of Agricultural Equipment: Challenges and Opportunities

Agricultural equipment manufacturing is one of the most strategically important sectors of national economyproviding to a large extent food security of the country. The modern society faces food problems, thereforeproblems of agricultural economy development, as well as problems of manufacturing modern agriculturalequipment competitive with foreign analogues; hence, the issue of studying the Russian market of agriculturalequipment is not only of current interest but as well of strategic importance. The article analyzes the condition ofthe Russian agricultural equipment market, which has been critically monopolized today. At the same time,negative tendencies fully formed in its system can exert negative and significant influence on the national foodsecurity (when the customers have no appropriate market choice of agricultural equipment; with vigorous pricemanipulations of the sellers; information failure as well as non-equal terms of market behavior for differentproducers). The authors believe that these tendencies cannot be resolved without active and cautious interferenceof the state specifically into the processes of developing highly competitive business environment. Besides, it isnecessary to work out the concept of accompanying infrastructural developments while manufacturing andmarketing the agricultural equipment; that will optimize the opportunities of the domestic manufacturers.

Attitude of Youth to Agricultural Development Programmes In Ughelli South Local Government Area of Delta State, Nigeria

The problems associated with youth behaviours in the Niger Delta region necessitated the study. The specific objectives were to collate the current agricultural development intervention programmes; compare the attitude of youth leaders and non-leaders to agricultural development intervention programmes, and examine the factors militating against youth involvement in agriculture. Questionnaires were used to elicit information from respondents. Simple random sampling was used to select respondents. The sample was made up of 71 youths comprising 18 leaders and 53 non-leaders. Data were analysed by the use of mean and t-test. It was found that 5 agricultural development programmes currently existed in the study area. The non-youth leaders disagreed with the 5 positive attitude statements and agreed with 4 out of the 5 negative statements. The youth leaders disagreed with 5 positive attitude statements and agreed with the 5 negative attitude statements. There was no significant difference in the mean attitude scores between youth leaders and non-leaders (t=0.05; p>0.05). The factors militating against youth involvement in agriculture were lack of basic infrastructure ( x=2.62), lack of modern agricultural equipment ( land/land tenure system ( incentives/ incomes( x=3.34), lack of credit facilities ( x=3.46), lack of x=2.99), and poor x=3.00). Youths should be motivated to take up agriculture through extension campaigns, and provision of inputs and land for large scale farming

Compression of intact subsoils under short-duration loading

Heavy axle loads of modern agricultural equipment greatly increase the potential for severe soil compaction. Axle loads exceeding 90 kN have been shown to cause compaction considerably below the depth of primary tillage. To evaluate the potential for compaction from heavy axle load traffic in the Pacific Northwest USA, compression characteristics of intact subsoil samples from eight agriculturally important soil series were determined. Clay contents of the soils ranged between 14 and 27%. Compactive stress thresholds (CSTs) of the subsoils, the stress at which irreversible deformation occurs, were determined at varying matric potentials (−30 to −300 kPa) using one-dimensional compression tests and short-duration loading (2-min). CST values for the eight subsoils ranged between 64 and 492 kPa, and increased two- to three-fold between −30 and −300 kPa matric potential. A relationship between CST and clay content did not exist, however, soils with high bulk densities generally had higher CST values than soils with low bulk densities. This implies that structural rather than textural characteristics exert a greater influence on CST under short-duration loading such as wheel traffic. For the range of soil matric potentials which occur during spring tillage in the Pacific Northwest (−30 to −100 kPa), the measured CST values ranged between 64 and 356 kPa. Wheel tractors and other equipment in the region have axle loads exceeding 90 kN and exert surface pressures ranging between 150 and 300 kPa. Since levels of subsoil stress under high axle loads can approach surface-applied pressures, the potential for subsoil compaction in these soils during spring tillage operations is high.
