Physical And Mechanical Characteristics

The article is devoted to the study of using mobile robotic systems in agriculture. It is shown that it is necessary to know the physical and mechanical characteristics of the main support motion surfaces to calculate the mobility and efficiency of these complexes. This will allow calculating the movement resistance and traction force, and as a result, choosing the best appliance design for these conditions. Typical areas of agricultural land near the village of Belka in the Knyaginino district of the Nizhny Novgorod region were analyzed. More than 200 measurements were made. The dependencies for calculating the main soil parameters are described. It is obtained that the average values of the soil parameters change within the following limits: the deformation modulus is 15.5-23 N/cm2, the specific soil adhesion is 13.9-16.7 kPa, the internal friction angle is 14.8-16.4 degrees, the density is 1.09-1.14 g/cm3, the soil moisture is 035-16, 9%.

The Village

Banyuwangi Regency is one of the agricultural centers in East Java province and Indonesia. Mostly,Banyuwangi people work as farmers due to the fertil soil and wide amount of agricultural land in Banyuwangi . Thelarge number of people who work as farmers initiating the formation of farmer groups. One of the farmer groups in theSrono sub-district of Banyuwangi is the "Tan Selo 1" farmers group located in the village of Sukomaju and the "TanSelo 2" farmers group in Sukonatar village. The normal average price of one banana bunch in Banyuwangi is between50-60 thousand depending on the type and quality of bananas. Problems arise when the quantity of bananas in the marketarose, the price of 1 bunch of bananas decreases dramatically. The price of 1 bunch which is usually set at 50-60thousand drops drastically to only 20-30 thousand. This is certainly a problem for farmers in the Tan Selo group. The lackof knowledge of Tan Selo farmers about alternative variants of processed banana based products and the lack ofknowledge of the marketing strategies make it hard for the Tan Selo farmers to increase the economic value of bananaswhich have been used as an alternative income for farmers. Therefore, the solutions offered to overcome the problems offarmers include: equipping and improving farmers' knowledge about the variety of processed banana-based foods andtheir marketing strategies, conducting training to make variations on banana-based foods, conducting training oneffective marketing strategies. Overall, a series of community service programs were carried out perfectly as it expected.The percentage of participants' understanding in choosing high quality bananas is 85%, the percentage of participants’ability in processing banana-based foods is 86%, and percentage of participants who successfully sell processed foodproducts by utilizing online shopping sites is 70%

Srem, as traditional farming, orchard and wine-growing region, faces the problem of shortage of water needed for agriculture. During the seventies of the last century brook valleys in the southern part of Fruska Gora loess plateau were intended to be dammed. Thus, artificial lakes could have been formed. It took long period of time to put these projects into practice and numerous projects have not started yet. After the dams had been built and lakes filled with water, planners faced hydro-geological problems at many locations. Nevertheless, these accumulations fulfill their primary function, i.e. they ensure water for irrigation and protect agricultural land from floods. There is a hydroaccumulation system, Calma lakes, near the village of Calma. Its primary function was to ensure water supplies for agriculture, but eventually it got new significance which can be noticed in fish raising and sport fishing development.

People who are known as Nayakas or Nayakadas in government offices call themselves Nayak, Nayaka or Nayakada is a name given in contempt by the so-called Upper cast which is recognized by the government so that even though this caste known as Nayaka or Nayak is a tribal, it has not got any benefit as a tribal till date. In Chhota Udepur and Pavi-Jetpur talukas of Central Gujarat, some Nayaks have a little more agricultural land. So they work in agriculture, farm labor and grazing cattle in the village. In Sankheda, Naswadi taluka they work as farm laborers and cowherds. The protagonist caste is the warrior caste. In the ChhotaUdepur region they revolted three to four times to preserve their estates. Nayak revolted in 1818, 1838, 1857-59and 1868 With the help of the states of Baria, ChhotaUdepur, Vadodara and Gwalior, the main leaders of the Nayak were captured, Some surrendered, some were punished, some were released on good bail. Today the economic condition of the Nayak caste is bad. Too bad. Lives as a village herdsman. Their dress is similar to that of other tribal castes in the central gujarat. They Wear aluminum jewelry. The present paper focuses on the cultural diversity of the respective Nayak Adivasi of Central Gujarat.

As lack of explicit analysis method on the sequence of many factors influencing the plastic zone extension of surrounding rock, the grey correlation analysis method is adopted to study the relationship between the plastic zone extension radius Rp and the six factors such as cohesive c, internal friction angle φ, deformation modulus E, unit weight γ, initial ground stress σ and the radius of chamber r. By dealing with dimensionless, the corresponding sequences composed with the sensitive factors as sub-sequence and the plastic zone extension radius as mother sequence are obtained. The gray correlation analysis model of sensitive factors which evaluates the results with grey correlation degree is built by the methods of dimensionless and extreme difference variation. Then, an engineering example is analyzed with grey correlation. Based on the analysis results, the sorting of sensitive factors is φ > σ > c > r > E > γ. It implies that the influences of internal friction angle φ and initial ground stress σ are the most prominent, and the sensitivities of deformation modulus E and unit weight γ are lowest. These are in good agreement with the analytical formula of classical theory, and can be used in guiding the further optimization and improvement of the analytical expression of the plastic zone extension radius Rp of surrounding rock.

Unsaturated Sands

The bearing capacity and settlement of foundations are determined experimentally or modelled numerically based on conventional soil mechanics for saturated soils. In both methods, bearing capacity and settlement are estimated based on the applied vertical stress versus surface settlement relationship. These methods are also conventionally used for soils that are in an unsaturated condition, ignoring the contribution of matric suction. In this study, a methodology is proposed to estimate the bearing capacity and settlement of shallow foundations in unsaturated sands by predicting the applied vertical stress versus surface settlement relationship. The proposed method requires soil parameters obtained under only saturated conditions (i.e., effective cohesion, effective internal friction angle, and modulus of subgrade reaction from model footing test) along with the soil-water characteristic curve (SWCC). In addition, finite element analyses are undertaken to simulate the applied vertical stress versus surface settlement relationship for unsaturated sands. The proposed method and finite element analyses are performed using an elastic – perfectly plastic model. The predicted bearing capacities and settlements from the proposed method and finite element analyses are compared with published model footing test results. There is good agreement between measured and predicted results.

One of the most common and practical difficulties a pipeline engineer faces at the initial stage of the project is the lack of Soil survey data. Hence, various soil parameters like soil type, density, friction angle, cohesive pressure, depth of cover, pipe coating etc. are needed to be assumed. The critical designs like anchor block requirement, pipe route changes, support loads which involve a huge cost are required to be ‘Issued for Construction’ based on assumed data. This paper briefly illustrates and compares the results obtained from the two most common buried pipe stress analysis methods viz. ‘American Lifeline Alliance - Appendix B’ (1) and ‘Stress Analysis Methods for Underground Pipelines’ (2) and shows their effects graphically on the various Stress Analysis results like pipe movement, end force, active length (virtual anchor length) and bending stress generated in the buried pipeline. Further, this paper comes up with an unique application of ANOVA, a Statistical method, to find out the most significant soil parameter affecting the said results. The paper explains this method with a solved example. These results are useful for a pipeline engineer to determine the governing soil parameter in the design and thus provide a useful tool to make optimum assumptions in absence of soil data so as to minimize the changes in future design and helps saving the cost of the project due to rework.

Cross Correlations

This paper focuses on the calculation of probability of failure of simple unreinforced slopes and the influence of the magnitude of cross correlation between soil parameters on numerical outcomes. A general closed-form solution for cohesive slopes with cross correlation between cohesion and unit weight was investigated and results compared with cases without cross correlation. Negative cross correlations between cohesion and friction angle and positive cross correlations between cohesion and unit weight, and friction angle and unit weight were considered in the current study. The factors of safety and probabilities of failure for the slopes with uncorrelated soil properties were obtained using probabilistic slope stability design charts previously reported by the writers. Results for cohesive soil slopes and positive cross correlation between cohesion and unit weight are shown to decrease probability of failure. Probability of failure also decreased for increasing negative cross correlation between cohesion and friction angle, and increasing positive correlation between cohesion and unit weight, and friction angle and unit weight. Probabilistic slope stability design charts presented by the writers in an earlier publication are extended to include cohesive-frictional (c-[Formula: see text]) soil slopes with and without cross correlation between soil input parameters. An important outcome of the work presented here is that cross correlation between random values of soil properties can reduce the probability of failure for simple slope cases. Hence, previous probabilistic design charts by the writers for simple soil slopes with uncorrelated soil properties are conservative (safe) for design. This study also provides one explanation why slope stability analyses using uncorrelated soil properties can predict unreasonably high probabilities of failure when conventional estimates of factor of safety suggest a stable slope.

The purpose of the Student Study Service Programs are 1) Synergizing socio-cultural local wisdom with community economic characteristics for preventing degradation of agricultural land through the KKN program. 2) Formulate strategies to increase the potential of villages towards developed and independent villages. The method of collection is done in two kinds, namely primary data by means of surveys, questionnaires and interviews with the village secretary, village apparatus, community leaders, farmer groups and residents around of Panggung Duwet Village’s related to the KKN program, and secondary data in the form of well-documented data such as Blitar Regency in the Numbers, Kademangan District in the Numbers as well as the Report on the Implementation of the Village Administration and/or the Report on the Accountability of the Panggung Duwet Village’s in 2018. The data analysis method was conducted using the social intervention and SWOT analysis approaches. The results of the implementation of the Student Study Service Programs in Panggungduwet Village, Kademangan District are implemented into a work program that is greening, processing waste into organic fertilizer and crafts, processing food commodities such as corn silk syrup, cassava donuts and cassava chips. Analysis of the village situation shown still has weaknesses, namely lack of water supply, especially in the dry season, especially agriculture in line with the opportunities that exist, namely seeking organic fertilizer by utilizing waste and wood sawdust crafts for sale so that the potential is expected to be a catalyst for village development to become advanced and independent. The existence of the Student Study Service Programs can leave a good impression so that the community is willing to begin to change the bad behavior of agricultural land management that ignores the rules of conservation and increased knowledge and skills of processed waste and food processed in order to improve the economic welfare of the community.

Purpose. The analysis of the surface water quality of the Stokhid river, the definition of the class and the category of water quality. Methods. Comparative geographic, analytical, generalization and systematization. Results. Inner annual dynamics of the components of the hydro chemical conditions of surface water composition is closely linked with river runoff, the formation of which occurs due to loss of precipitation and nutrition of groundwater. Based on the analysis of monitoring observations, carried out by the State Environmental Inspectorate in the Volyn region for the period from 2007 to 2017, it has been determined the multi-year time and spatial dynamics of the average annual values of integrated environmental indices by the average values. They are following: in the village Malinovka IEaver. = 2,2 and in Lyubeshiv village IE aver. = 2,4. The water of river Stokhid belongs to the second class of quality ("good", "pure"), to the second category ("very good", "very pure") and subcategories 2 (3) ("very good", " clean" water with a tendency to approach the category of "good", "fairly clean") respectively. Dynamics of average annual values of integral ecological indexes for the worst values in village Malinovka IEworst = 2,6 and in the village Lyubeshiv IEworst = 2,8 was characterized by water of the second class ("good", "pure"), third category ("good", "fairly clean"), subcategory 2-3 (water transitions in quality from "very good", "pure" to "good", "fairly clean") and subcategory 3 (2) ("good", "fairly clean" water with a bias to "very good", "clean"). Conclusions. In general, it should be noticed, that when calculating the values of integral ecological indexes, the value of the indexes of trophic and sapro-biological indicators are the worst. Compounds of Nitrogen was among the substances that determined the water quality as "very poor" and "very dirty". Increased levels of Nitrogen compounds in the Stokhid river is mainly due to the intake of insufficiently treated wastewater, surface runoff from agricultural land and the decomposition of non-living organic matter in the spring.
