Published: January 2022

Abstract
A cropping pattern is an effort to plant things on a plot of land by arranging the layout and order of plants for a certain period of time. Cropping patterns and or intercropping can be done with the aim of utilizing resources optimally and to avoid the risk of crop failure and market risk. Diversified cropping patterns are farming diversification with the aim of increasing agricultural yields so that income is maintained. The purpose of this research is to determine the types of farming patterns based on beef cattle, the impact of farming patterns on business objectives, and the income generated from the Decent Living Needs (KHL) that applies on dry land. Decent Living Needs (KHL) is the standard of needs of a single worker/labor to be able to live physically decently in 1 month. KHL is also the basis for determining the Minimum Wage. The study was carried out in Takisung District, Tanah Laut Regency, South Kalimantan. A survey and focus group discussions were used as research methods. Income, livestock waste for fertilizer, agricultural waste for feed, utilization of agricultural land, forage area, and livestock weight gain are the business objectives that are determined and analyzed. The analysis used is analysis of variance (ANOVA), and the Duncan test will be used to determine the contribution of income to the KHL. The research found six dominant cattle-based farming patterns. Farming patterns have a significant impact on business objectives such as income, agricultural waste utilization for animal feed, and agricultural land utilization. The conclusion of this research is that there are 6 dominant farming patterns in the research location, namely paddy and cattle; paddy, rubber and cattle; paddy, rubber, soybeans and cattle; Paddy, soybeans and cattle; paddy, soybeans, peanut and cattle; paddy, corn and cattle. The pattern of business that produces the highest income is the pattern of rice, rubber and cattle and the second is rice, soybean, rubber and cattle. The recommended business is business diversification with several commodities so that the necessities of life can be achieved and sustainable.

Published: January 2022

Abstract
The manufacturing industry is the main source of Indonesia’s economic growth. Its contribution to national GDP (gross domestic product) in 2012 is 22%, and it is expected to reach 30% in 2035. On the other hand, the industrial sector consumes energy which produces greenhouse gases. In 2017, the final energy consumption of the industrial sector was 232 million BOE (barrels of oil equivalent), slightly below the transportation sector, which was 362 million BOE. This study analyses the relationship between economic growth in the industrial sector and greenhouse gas emissions. Data for the period 2002-2018, with a cross section of 8 manufacturing industry subsectors, was analysed using regression models. The results of the analysis show that economic growth is positively related to greenhouse gas emissions, namely in the chemical fertilizer and rubber goods industries; cement and non-metal minerals industries; as well as raw metals iron and steel industries.

Class D or area with high development capability takes the widest part or 4,394 Ha (74.4%) and the rest 1,508 Ha (25.6%) is Class C or moderate development capability. Based on this condition, the direction of settlement development could be developed is about 26% or 190.3 Ha. Therefore, appropriate direction is needed for the sustainability of settlements in the future.
Future Spatial Prediction of Invasive Plant Merremia peltata in Indonesia
Authors: Yudaputra A 
Published: January 2022

Abstract

Merremia peltata is a woody vine that considered as invasive plant. It causes serious threats to the regeneration of native plant. Many strategies to control its invasiveness have been continuously implemented, but climate change causes complicated problems. This study aimed to understand the impact of climate change to its current and future distribution. Ensemble model by combining Random Forest and Support Vector Machine was used to predict its distribution. There were 33 occurrence records derived from Global Biodiversity Information Facility and reliable scientific journals. The 19 climatic variables were tested using a multicollinearity test. AUC and TSS were used to evaluate the model. Multicollinearity test using 0.7 threshold produces 7 selected climatic variables. AUC and TSS have the value >0.80 indicating the model has good performance. The predictive future distribution map shows that its distribution shifts to other regions in 2070 compared to the predictive current distribution. The predictive current distribution covers 30.4 % of the total land areas of Indonesia, while the predictive future distribution (RCP 4.5) covers 28.12 % and RCP 8.5 covers 23.59 %. It indicates that the suitable geographic distribution areas of M. peltata reduces around 3-7 % of the total areas of Indonesia in 2070.
Optimum Tuning Parameter Selection in Generalized lasso for Clustering with Spatially Varying Coefficient Models
Authors: Rahardiantoro S , Sakamoto Wataru 
Published: January 2022

Abstract
Spatial clustering with spatially varying coefficient models is useful for determining the region with common effects of variables in spatial data. This study focuses on selecting the optimum tuning parameter of the generalized lasso for clustering with the spatially varying coefficient model. The k-fold cross-validation (CV) may fail to split spatial data into a training set and a testing set, if a region contains only a few observations. Moreover, the k-fold CV is known to give a biased estimate of the out-of-sample prediction error. Therefore, we investigated the performance of approximate leave-one-out cross-validation (ALOCV) in comparison with k-fold CV for selecting the tuning parameter in a simulation study on 2-dimensional grid. The ALOCV yielded smaller error than k-fold CV and could detect edges with differences shrunk by generalized lasso appropriately. Then, the ALOCV for selecting the optimum tuning parameter of the generalized lasso in fitting the spatially varying coefficient model is applied to the Chicago crime data. The result of selection by ALOCV was in accordance with the conclusion suggested in the preceding literature. Clustering into regions in advance for making k-fold CV feasible may lead to a wrong result of clustering with a spatially varying coefficient model.

Published: January 2022

Abstract
The increasing need of land for building roads, settlements, and other facilities leads to the changes of agricultural land to other uses. Uncontrolled changes in rice fields may negatively impact economic, social, and environmental aspects. This study aims (1) to analyze the dynamics of land-use change for lowland rice in the surrounding Cipali toll road of Subang Regency; (2) to delineate rice-fields being converted to other uses in the vicinity of the Cipali toll road; (3) to assess the impact of rice-fields conversion to rice production; and (4) to understand monitoring system for rice field conversion being implemented in Subang Regency. This research employed random forest classifier, post-classification change analysis, and analytic hierarchy process. Three Landsat imageries were used to identify change processes, span between 2000 and 2020. Random forest classifiers generated accuracy at 99%, 96%, and 96% in 2000, 2010, and 2020. The results showed a decrease of rice fields in the surrounding toll roads by 560.36 hectares from 2000 to 2010, followed by an increase in the next decade by 98.79 hectares. Revitalization of regional farm fields appears to effectively sustain production areas, albeit conversion occurred in the surrounding toll roads. Generally, rice field conversions were controlled following the regulation that was enacted to sustain land for crop production.

Published: January 2022

Abstract
The paper presents data on the separation of two-component mixtures of agricultural seeds by means of low-frequency horizontal vibration. Experiments were carried out with beans, peas and sunflower seeds. Modelling of the separation process of mixtures by the method studied in this work shows that the trajectory of a particle is a vortex along an ascending or descending line, depending on the combination of the properties of the components and operating parameters. The studies have shown that the minimum time for complete separation of the mixture into components is achieved when the container inclination angle is approximately equal to the repose angle of mixture components. The separation process is carried out only at amplitudes smaller than the particle size of the mixture.

Published: January 2022

Abstract
Ozonation enables to abandon the pre-sowing seeds treatment with pesticides, reduce their possible use. The effectiveness of ozone application equals to that of chemical disinfection. However, during pre-sowing ozone treatment of seeds, it is difficult to maintain the specified operating modes of the ozonizer. Therefore, it is much easier to vary the operation time with regards to the capabilities of a particular ozonation plant. Thus, the most rational modes of pre-sowing ozone treatment of seeds were determined based on the crop and the average concentration of ozone in the ozone-air mixture. The ozonation time should be in the range 23 … 41, 32 … 52, 40 … 60 and 17 … 45 min during pre-sowing ozone treatment of the seeds of winter wheat, spring barley, oats and maize with ozone concentration in the ozone-air mixture equal to 4.21, 2.57, 1.45 and 1.87 mg/m3, respectively. If the ozonizer fails to maintain a specified operating mode, then the dose of ozone treatment should be regarded. The ozone treatment dose for winter wheat varies from 96 to 234 min mg/m3, for spring barley – from 84 to 116 min mg/m3, for oats – from 45 to 86 min mg/m3, for maize – from 32 to 75 min mg/m3. In this case, it will be necessary to calculate the ozonation time depending on the actual concentration of ozone in the ozone-air mixture. The average duration of pre-sowing ozone treatment of grain crops is 38 minutes.

Abstract
This article discusses the prediction of the characteristics of the technical condition of machines and their effectiveness. The task of predicting the parameters of the changes the technical state of agricultural machinery during operation is to determine the numerical characteristics for future points in time. When choosing and justifying a mathematical model, it is necessary to take into account the physical nature of the phenomena that lead to a change in characteristics during operation. A model reflecting the rate of change of parameters is used to describe the processes. In forecasting, to increase the efficiency of the mathematical model, generalized physical laws are used that determine the process of changing the resource. Based on this model, it is possible to build a methodology for calculating the reliability. The set of process characteristics characterizes the change in parameters and makes it possible to predict torque functions during operation.

Abstract
The article discusses the results of investigations carried out within the framework of the research project commissioned by the Ministry of Agriculture of the Russian Federation in 2020. In August 2019, a field experiment was laid for the disposal of straw of spring barley of Vladimir variety using a special machine for this, i.e. a unit for utilizing the non-grain part of the crop as a fertilizer. When disposing straw, it was processed with biopreparations-destructors: Agrinos-1 (2 l/ha), Sternifag SP (0.08 kg/ha), Biocomplex BTU (1 l/ha), humic product Ekorost (0.4 l/ha). The straw was crushed and embedded in the soil on the control plot without treatment with biological preparations. It was found that the process of straw decomposition is more intensive compared to that of 2018-2019 on average by 5 %. The variants with Agrinos 1 and Sternifag SP treatment showed better results and accelerated the degradation process by 20 % compared to the control. The biological productivity of spring oats of Skakun variety showed that all studied biological products had a positive effect on the increase in yield. The best indicators were achieved on the variants with Agrinos-1 and Sternifag SP equal to 48.9 dt/ha and 45.4 dt/ha, respectively (the control was 36.4 dt/ha).

Published: January 2022

Abstract
The study reveals the disadvantages of technical units intended for sowing grain crops. Vectors of modernization of existing and the design of new working bodies of sowing equipment were identified. The arrangement and principle of ploughshare operation for different depth sowing of seeds and fertilizers is described. The results of the planned experiment are presented, the regression equations are obtained describing the process of changing the uniformity of seeds distribution along the length and width of the planted furrow. Based on regression equations, response surfaces, uniformity of seed distribution along the length and width of the planted furrow are built depending on the design parameters of a ploughshare. The experimental studies revealed that the uniformity of seed distribution (85.5 % in length and 76.3 % in width of the planted furrow) is achieved with the following ploughshare parameters: drift angle α=15 degrees; roll angle β=15 degrees; cutout length of a lower edge of a leg L=50 mm. With these design parameters, the proposed ploughshare provides a uniform depth of seeding-down and meets the corresponding agricultural requirements. At the same time, mineral fertilizers are embedded below the horizon of the main crop at 30…40 mm.
Methodological fundamentals for obtaining high quality food grain and increasing the yield of winter wheat in crop rotations of Central Chernozem Region
Authors: Dudkina T A , Dolgopolova N V 
Published: January 2022

Abstract
The increase in the production and application of organic and mineral fertilizers, the cultivation of crops using intensive technology require the balance of the elements of productivity at the highest level. One of the leading places among them is occupied by plant nutrition. The intensive technology is characterized not only by a high level of fertilization, but also by the exact adherence to the rates, timing and methods of application. The ultimate goal of the intensive technology is not only to increase yields and improve the quality of winter wheat grain, but also to maintain or increase soil fertility. It was found that fertilizers improved the quality of wheat grain in all years of the study. Fractional application of nitrogen led to an increase in the content of protein and gluten in the grain in all the studied links of crop rotations. In increasing the yield of agricultural crops and the quality of grain, the development of scientifically substantiated crop rotations with correct alternation of crops in them in relation to specific soil and climatic conditions is by no means unimportant. Crop rotations also influence the elements of soil fertility. Changes in the structure of sown areas should be carried out taking into account the need to increase the area under high-yielding crops, both grain and row crops.
