Published: February 2022

This paper is motivated by the existence of new innovations in the world of capital markets and banking, namely an investment sukuk (state sharia securities) which is a bond investment based on sharia principles that can be issued by companies or governments. Sukuk investment is issued to finance the state budget, including the construction of a project. There are various types of sukuk investments because the contracts used when investing also vary. Every investment will certainly cause losses for the parties, so this will also be a loss for every investor who makes an investment, as well as sukuk investment, investors can also experience the risk of loss. Losses that can be experienced by each investor are different due to the different contracts in investing in sukuk. Loss experienced by investors is caused by negligence on the part of the management (company) then the company must be responsible for losses incurred due to negligence, the extent to which the company's responsibility depends on how much negligence the company did to cause losses to investors.How to cite item: Mochtar, D., Rahayu, D.

Published: February 2022

This paper aims to analyze the urgency of the supervisory authority of the Financial Services Authority (OJK) on fundraising activities by non-financial institutions. For the purpose of discussion, this type of normative legal research uses a statutory approach, an analytical approach, and a case approach. Primary and secondary legal materials were analyzed using grammatical and systematic analysis techniques. Based on the results of the discussion, it was concluded that the Financial Services Authority's supervisory authority over the activities of collecting funds by non-financial institutions was that the Financial Services Authority had no authority. Based on the provisions of Articles 4, 5, 6, and Article 34 of the BI Law and their explanations regarding the regulation of OJK's supervisory functions, objectives, and authorities, it can be concluded that OJK's supervisory authority is limited to only covering financial service sector institutions, both banks, and non-banks. Meanwhile, First Travel is categorized as a non-financial institution in the form of a travel agency for Hajj and Umrah, although First Travel carries out fundraising activities. It is also strengthened that First Travel is not an official entity under the authority of the OJK in terms of licensing, regulation and supervision. First Travel status has received permission from the Ministry of Religion of the Republic of Indonesia but raises funds that are not in accordance with the license held. So, in the case of First Travel, it should have been sufficiently handled by the Ministry of Religion of the Republic of Indonesia, because that ministry was the one that issued permits and carried out supervision.How to cite item: Zuhriyah, S., Negara, T., Kawuryan, E.

Perkembangangan peran pecalang sebagai lembaga keamanan adat di masyarakat Bali Indonesia
Authors: Indrayanti Kadek Wiwik
Published: February 2022

The island of Bali is known as one of the world's tourist destinations with all its unique traditions and customary laws. The Balinese have a traditional security institution known as the Pecalang whose role is different from that of the police. The purpose of this article is to identify the position of Pecalang according to Regional Regulation Number 4 of 2019 concerning Traditional Villages and the development of the role of Pecalang. The method used is a mix of methods, namely normative and empirical methods. The results show that the existence of Pecalang is regulated in Law Number 9 of 1979 concerning Village Government and Regional Regulation Number 4 of 2019 concerning Traditional Villages. Pecalang is formed in each of the customary village residents (pekraman) who have the task of maintaining security and order. The role of pecalang is currently experiencing development, which leads to the business, and can even be used as a political tool. What stands out is the case of the closure of the Hare Krsna hostel where the function as a security guard was instead used as a tool by the village to bring order to religious groups or sects that were allegedly not in accordance with community traditions. The police should have been involved because they thought it was a religious matter and their area. The regulation of pecalang duties needs to be re-examined in the Perda so that its function as a guardian of order is clear and not vice versa.How to cite item: Indrayanti, K. (2021).

Published: February 2022

The use of a drip irrigation system allows the most efficient use of irrigation water, since it is delivered directly to the root space. In recent years, the production of drip tape at domestic enterprises has significantly increased by introducing additional capacities at existing plants and commissioning new production facilities, which will halve the import of drip tape and related equipment and fittings. However, the share of lands occupied by drip irrigation among the territories using irrigation measures has practically not increased and amounts to 2-4 %. The design of drip irrigation systems, taking into account the peculiarities of the growing season of a particular agricultural crop, its dynamics of water consumption throughout the life cycle, and the planting scheme, will help to change the situation and expand the use of drip irrigation. One of the limiting factors is the low degree of mechanization when laying the drip tape. The use of handicraft devices for these purposes leads to an uneven tension of the tape and, as a consequence, its breakage and twisting during the laying process. To eliminate this drawback, the working equipment for laying the drip tape into the potato comb was developed and installed on the Grimme GF-75/4 comb shaper. Traction resistance increased by 6-8 %, without affecting the performance of the machine. During the tests, a brake system was installed that maintains the belt tension within acceptable limits and prevents the coil from spinning when the machine stops suddenly. The use of a drip tape stacker based on the Grimme GF-75/4 ridge former has increased the productivity of work by 32–36 %.

Until now, almost the only way to ensure symmetrical loading of AC networks with a voltage of up to 0.4 kV is to connect the load as uniformly as possible to the phases of the three-phase network. This technique does not provide constant symmetry of the load, which entails a decrease in the throughput of power networks and transformers, an increase in network losses, and a decrease in the reliability of power supply to consumers. The authors propose an innovative device for symmetric distribution of single-phase load over phases of a three-phase network. This allows us to solve a number of problems related to the reliability of electricity supply, accidents, electrotraumatism, failures of the energy supply system and reducing the time of interruptions in energy supply, and, therefore, losses of manufacturers

Published: February 2022

The identification of factors that affect the decrease in the yield of hard wheat is the basis for studying plant diseases in the agrometeorological conditions of the Orenburg region. In this regard, field and laboratory studies are being conducted on common root rot (Bipolaris sorokiniana) of durum wheat. In the research work, the method of field experience was applied, the weather factors, the infestation of crops with root rot and the yield of durum wheat grain in crop rotations and during permanent cultivation in the southern black lands of the Urals were taken into account. The research was carried out for the first time from 2015 to 2020 on a long-term stationary experimental plot on crop rotations and permanent crops, laid down in 1988 on the territory of the OPH n.a. Kuibyshev. On average, during the growing season of the crop (durum wheat), 107 mm of precipitation falls at an average monthly air temperature of 20.3 oC and the number of dry days is 68. The results of the study show that the lowest prevalence and development of root rot reaches 28.6 and 10.2 % in the third variant of the experiment on a non-windy background of nutrition, the dependence on the influence of air temperature is 94.4 and 70.0 %. The highest yield of durum wheat grain was obtained in the fallow field with siderates in the average arid year of 2017 and amounts to 2.14 and 2.11 t / ha after the application of mineral fertilizers and without them. In the fourth version of the experiment, there is a decrease in the yield of durum wheat grain, which depends on the development of root rot at the maximum proportions of the influence of 80.0 and 89.7 %. Various agro-meteorological conditions, precursors and food backgrounds are the main cause of changes in the degree of spread and development of durum wheat root rot.

In the diets of laying hens, readily available protein is the second most important nutrient in cost. With the development of the poultry industry, the need for good and high-quality feed also increases. Soybean and sunflower meal and oil cakes, which are familiar to us, cannot fully provide egg-based poultry farming with protein. This publication discusses the replacement of soybean meal and sunflower meal with heat-treated lupine in the diets of laying hens. The correction of the diet with the introduction of heat-treated lupine - 3% and the data obtained in the course of the process is analyzed. To study the effect of lupine on the productivity and safety of birds of the Lohmann Brown-Classic cross, a scientific and economic experiment was carried out, where two groups of birds were selected. The control group received the main diet without lupine, and the experimental group received the diet with heat-treated lupine. In the experimental diet, soybean meal and sunflower meal were partially replaced with heat-treated lupine. Partial replacement of heat-treated lupine in diets for laying hens showed positive dynamics, namely, an increase in egg productivity and safety. Replacing soybeans and sunflowers with lupine reduces the cost of the diet.

The results of evaluating the effectiveness of health-improving measures against cattle leukemia in the Pavlodar region are presented. In the Pavlodar region in 2018, 7065 heads of cattle were examined for leukemia, 434 reacted positively, the percentage of infection was 4.8. In 2019, 5354 heads were tested for leukemia, 187 responded positively, the percentage of infection was 3.9. In 2020 (6 months), 3394 heads were examined, 139 heads reacted positively, the percentage of infection was 5.4. Despite the health improvement measures carried out in the region, leukemia of cattle is still registered in five out of 13 districts. At the same time, in some regions, the number of animals studied (Lebyazhinsky, Zhelezinsky, Irtyshsky, Uspensky) noticeably decreases, and in some cases, the number of positively reacting animals increases two or more times. So, for example, in Zhelezinsky district, with a decrease in the number of animals studied (from 1672 to 456), the percentage of infection increases from 0.42 to 9.65. Thus, the results of the study showed that the Pavlodar region was and remains an unfavorable region for bovine leukemia. Recreation measures do not give the proper efficiency and the region remains among those who are not safe for leukemia in cattle along with Kostanay (6.6%), North Kazakhstan (4.7%), East Kazakhstan (3.7%), and studies in 2020 showed an increase in the incidence of up to 5.4%.

Authors: Kirdey Tatiana Aleksandrovna
Published: February 2022

Salinity  is  one of the chief factors of soil fertility decreasing and soil degradation. The influence of lowland peat humus acids preparation on spring wheat (Triticum aestivum L.) resistance to progressing chlorine salinity was investigated. The plants were grown in aquatic culture on Hogland nutrient mixture. The progressing salinity was created with the help of NaCl concentration from 25 to 100 mM by 25 Mm step every 14 days. Variants of permanent salinity included 75 and 100 mM.  In all the variants of the experiment the plants were grown with addition of peat humus acids preparation (0,005%) or without it. In the result of the experiment it was stated that humic acids protective action is more manifested under strong stress influence,   NaCl permanent concentration being 100 Mm, herewith the degree of plants salinity resistance in presence of humic acids increases 1,5-2 times. Under progressing salinity humic acids preparation protective action is observed only on the 14-th (25Mm) and 28-th (50 Mm) days after salinity beginning. Peat humic acids preparation was found to decrease Sodium accumulation in wheat shoots almost twice under progressing salinity up to 100Mm and 2,3-2,7 times in the variants of permanent salinity.

Published: February 2022

The review summarizes works, usually in English, related to the assessment of changes in the con-tent of "classical" and "new" endogenous phytohormones in various plant species under conditions of environmental pollution with heavy metals. Most of these studies in recent years have been relat-ed to the study of hormonal balance in plants of the genus Arabidopsis. It is shown that the intro-duction of one metal can upset the balance of several representatives of this class at once. In addi-tion to describing regulatory shifts in response to induced stress, the review presents a conceptual scheme of cross-signaling that is responsible for maintaining overall immune homeostasis in plant ontogenesis. This work provides a broad theoretical basis for future research when working not only with agricultural crops, but also with medicinal or flower-ornamental plants.

Published: February 2022

Studies were conducted in the Ulyanovsk region to determine the optimal elements of the spring soft wheat cultivation technology (predecessor, method of basic tillage, fertilization, seeding rate), which provided the greatest economic efficiency in the forest-steppe of the Volga region. It was found that shallow tillage provided an increase in productive moisture reserves during the entire vegetation, both for the cereals and for the leguminous predecessor. On plowing, in the 0-30 cm of soil layer the content of nitrate nitrogen increased after sowing of the studied crop and the dry weight of weeds decreased. For peas, the yield of Ulyanovskaya 105 was 0.6 t/ha higher than that for winter wheat. The highest yield (4.74-5.85 t/ha) for the stubble predecessor and (5.79-5.99 t/ha) for leguminous predecessor was formed one the mineral fertilizers background. Plowing in relation to shallow tillage provided an increase of 0.75 t/ha for winter wheat and only 0.13 t/ha for peas. The smallest coefficients of water consumption (457-481) for the stubble predecessor and (462-472) for the leguminous predecessor were formed for plowing on the third fertilization background. For winter wheat, the maximum profit (15.1 thousand rubles/ha) was obtained when sowing with a seeding rate of 5.5 million/ha for plowing on a 2 mineral fertilizer background, and for peas — when sowing with a seeding rate of 5.0 million/ha for fine tillage on 1 background and with a seeding rate of 4.5 million/ha for plowing on the 2nd mineral fertilizer background — 16.2 thousand rubles/ha in both variants.

Published: February 2022

The purpose of the research was to determine the publication activity of agricultural science. The analysis uses data from the leading international scientometric systems Web of Science (WoS) and Scopus. The authors compared the number of publications and citations in the framework of priority G of the Strategy for Scientific and Technological Development of the Russian Federation (SNTR), which includes key areas of development of the agro-food complex. Russia was compared with the leading countries of the world in terms of publication activity, mainly for 2010-2020, on the basis of which a world map was compiled and a ranking of states was conducted. It is established that the literature on agricultural sciences occupies an insignificant share among all scientific literature in Russia and in the world. The structure of publications in the areas of priority of G SNTR is defined. With the help of semantic analysis, priority directions of advanced scientific thought are identified, which allows us to predict the subsequent appearance of progressive technologies and innovations. The world and Russian research agendas were compared, which made it possible to identify coincidences and differences in scientific topics. The necessity of taking into account the specifics of the domestic agricultural sector when choosing research priorities is justified. The expediency of combining the use of advanced technologies with the preservation of effective traditional production methods is emphasized, which contributes to the realization of the competitive advantages of the Russian agri-food system. The number of Russian journals according to the priority of G SNTR in the WoS and Scopus systems with their distribution by quartile is shown. The data of comparative analysis of leading countries in terms of citation indicators, as well as comparison of patent activity, export and import of technologies to Russia are presented.

In the first group, 56 EAB alleles were identified, in the second – 46. The frequency of occurrence of the main alleles in the groups is 0.763 and 0.774. Among them, five marker alleles are found with a high frequency of 0.44 – 0.116. Alleles of the EAB locus b, A1B/, B1G2O1, O1Y2E/3G/G//, O2A/2J/2K/O/, Q/ are more common in high-yielding cows by 2.5 – 7.2 %, and the EAB alleles B2O1, O/, E/3G/G// are not found or are less common. When comparing the productivity of cows with different EAB – alleles, differences were noted. Lifetime productivity in cows with EAB alleles O1, I1Y2E/3G/G//, O2A/2J/2K/O/, I2, A/1B/ is higher than in cows with EAB alleles E/3G/G//, BI1Q, Y1A/1, I1Y2I/. There is a significant difference in the duration of use in cows with the EAB-alleles O1, O1Y2E/3G/G//, O1I/Q/, I1O2A/2K/Q/. There were no significant differences in the content of fat and protein in milk.

The article provides information about the effect of different doses of the  bioactive additive Lamarin Saldonum on the morphological parameters and immunobiochemical status of highly productive cows. The experiment involved 40 mature cows of the black-and-white Holstein breed, divided into three experimental and one control groups, with a milk yield of 7,500 kg of milk for the previous completed lactation. It is found that the use of biologically active additive from Japanese kelp and milk thistle in the rations of highly productive cows stimulates redox reactions occurring in the body of animals, which is confirmed by an increase in the level of hemoglobin in their blood by 3.92-8.63% in the first and second months of lactation,  and also in increase the number of red blood cells – by 4.47-9.17% in comparison with the control group. The positive effect of the studied supplement on the immunological parameters of animals, their protein and carbohydrate metabolism was also established, what is expressed in an increase in the level of total protein by 7.66-19.15%, it's albumin and globulin fractions by 11.15-16.91% and 15.40-25.03%, the amount of glucose by 19.12-29.60%, and level of total immunoglobulins by 7.66-13.51%, as well as in a decrease in the values of alaninaminotransferase by 12.83-20.99% and total bilirubin by 25.09-43.54% in comparison with the indicators of animals in the control group.  The best action of the additive is shown when it is used for 60 days in doses of 0.2 and 0.3 g/kg of body weight.

The article presents the results of a theoretical analysis of the regularities of mass transfer occurring during the technological impact on soybean grain in a liquid environment during the inactivation of anti-nutrient substances. Based on the classic hydrodynamic patterns occurring during mass transfer in biological material, it is established that processing of soybean without further intensifying the process influences not rational from the perspective of productivity and quality of manufactured products. To this end, the article considers the issues of controlling the mass transfer process by influencing the driving forces and, accordingly, the diffusion coefficient of additional means that intensify the process.

The article presents the results of bacteriological and molecular genetic (PCR) diagnostics of swine streptococcosis complicated by pasteurellosis (P. multocida) and mycoplasmosis (M. hyorhinis). Immunomodulator tamox, antibacterial preparations duphamox, melovem, containing amoxicillin, and melovem were used to reduce the symptoms of lameness and the degree of inflammation. Pregnant sows and weaned piglets without signs of disease were given specific prophylaxis using a streptococcosis vaccine (ImportierterspezifischerImpfstoff). The health improvement measures allowed the livestock to be sanitized from bacterial infections, including streptococcosis and pasteurellosis, but this did not affect the infection of piglets with mycoplasmas.

Modern technologies of feeding and keeping farm birds are based on keeping them in a special room. The content of birds in cages is explained by the fact that the manufacturer uses every cubic meter of useful space contained in it as efficiently as possible. Industrial poultry farming, as the most knowledge-intensive and dynamic branch of the agro-industrial complex, makes a significant contribution to providing the population of developed countries with food. The intensification of the process of keeping birds suggests the maximum use of the volume of these premises. For this reason, birds are placed in high-density cell batteries. In such conditions, birds practically do not get fresh air and sunlight. In this regard, the physiological state and productivity of the bird depends on the parameters of the indoor air environment. Therefore, there are such scientific and practical tasks as the development of technical means based on resonant power systems and modern optical radiation sources. In this regard, the scientific justification of energy-resource-protective lighting and irradiation equipment for poultry farming is also very relevant.

Published: February 2022

The article presents the results of three-year studies of the effect of biological products produced by the All-Russian Research Institute of Agricultural Microbiology (St. Petersburg) and mineral fertilizers, when applied jointly and separately, on the yield of sunflower on ordinary chernozem in the north-western zone of the Rostov region. The research carried out made it possible to give recommendations on the differentiation of sunflower nutrition control when producing products with different characteristics. For the production of oilseeds of ordinary quality, the greatest effect was after N60P40-fertilization during cultivation in spring. The increase in yield to the control was 0.31 t / ha, or 22.6%. To reduce the intensity of spring field work, autumn N60P40K40- or N60P80-fertilization during plowing will be equivalent. If it is necessary to reduce the anthropogenic load on the agrocenosis and produce agricultural products of improved quality, N30P40-fertilization in spring in combination with the application of the biological product Mizorin 7 into the rhizosphere of plants should be preferred. The increase in yield to control was not inferior to the traditional fertilization system. In order to obtain organic products without mineral fertilization, it is advisable to adjust the nutrition of sunflower only by application of biological preparations with strains of associative nitrogen fixers into the rhizosphere - Mizorin 7, Mizorin 204 and 2P-7. This agricultural practice increased the yield of sunflower sowing by 11.7-14.6%.
