In the current work, an attempt has been made to investigate the effect of tool rotational speed on microstructural and mechanical properties of friction stir welded AA6082-T6 aluminium alloy. Four different tool rotational speeds such as 500, 700, 900 and 1100 rpm were used to produce the joints while keeping the other process parameters constant. The tool used to fabricate the welded samples was tungsten carbide with straight cylindrical pin profile. The microstructural properties were examined using an optical and scanning electron microscope and found that the 700 rpm produced joint showed equiaxed grain structure with 14.3 μm average grain size. The mechanical characteristics such as tensile strength, impact strength and microhardness were evaluated and found the highest tensile strength of 265 MPa, impact energy of 10 J and micro hardness of 76 HV in the weld zone for the sample prepared with 700 rpm tool rotational speed. The fractographic studies were also carried out to study the mode of failure.

Deskripsi Kualitatif Terhadap Peran Media TV Swasta Dalam Mensosialisasikan Kandidat Pilwali Di Kota Makassar
Authors: Nur Emil Syah
Published: May 2020

Abstrak, Media TV sebagai media elektronik bertindak sebagai penyalur informasi seputar Pemilukada maupun sebagai media sosialisasi aktor politik untuk memperoleh dukungan. Meskipun media TV dapat diakses oleh setiap lapisan masyarakat, namun pengetahuan masyarakat terhadap politik maupun kesadaran untuk menggunakan hak pilihnya masih rendah. Penelitian ini adalah penelitian kualitatif  menggunakan teknik pengumpulan data wawancara dan observasi. Hasil penelitian menunjukkan  peran media televisi dalam mensosialisasikan kandidat calon walikota Makassar menunjukkan bahwa kemampuan untuk memahami dan mengeksploitasi kemungkinan bebagai tawaran dari media massa untuk memproyeksikan profil seseorang sekaligus mencapai serta memanipulasi publik massa. Oleh karena, eksistensi TV swasta dianggap berpotensi untuk mengkonstruksi wajah politik di Kota Makassar.Peran media televisi swasta di Kota Makassar dapat dilihat dari netralitas dalam mensosialisasikan kandidat calon Walikota Makassar dapat dilihat dari netralitas televise dalam menyampaikan visi dan misi. Netralitas media telvisi dalam kapasitas sebagai media sosialisasi  tercatat sebagai pendukung pasangan kepala daerah khususnya di Kota Makassar. Konsep netralitas  belum mampu mendukung peran televisi dalam mensosialisasikan calon walikota Makassar. Hal ini dapat dilihat dari  keberimbangan (balance), ketidakberpihakan (impartiality), keadilan (fairness), dan obyektivitas (objectivity) kurang mampu terlaksana dengan baik.
Broompare in sunflower crops and control methods
Authors: Ivashchenko O.
Published: May 2020

Goal. The study of the biological characteristics and developing methods for effective control of Broomrape in sunflower crops.

Methods. The comprehensive study included the route survey of crops in the five regions of the country where traditionally the acreage of sunflower is the largest part in the structure of arable land. Was conducted sampling of the soil in the fields to assess the level of contamination by seeds of Broomrape. Repeated the test 4. Surveys and monitoring of the crops was carried out in accordance with the requirements methods of testing and use of pesticides.

Results. Studies show that the presence of 2—7 of Broomrape stalks per 1 m2 of sunflower crops leading to reduced yields of seed cultures by 10—15%. In the presence of 35—40 pieces/m2 of stalks of the parasite reduction reaches 70—85% of the possible yields of crops. Sample survey of crops of sunflower and soil samples from the arable layer (0—30 cm) during the study years (Zaporizhzhia, Dnipropetrovsk, Odesa, etc.) and their analysis for the presence of seeds of Broomrape showed a high level of contamination. In the upper part of the topsoil (0—10 cm) found 124—1160 seeds/m2 seed of the parasite. However, only a 0.012—0.22% of the total quantity present in the soil of seeds of the parasite germinate in the spring as a result of interaction with the roots of the plant opinion. Easier to just hit the Broomrape seedling primary roots of sunflower plants in the juvenile and amatory stages of organogenesis (May — June).

Conclusions. The practice of using resistant against the respective races of Broomrape sunflower hybrids ensures to provide only a temporary and partial positive results. Immune to defeat different races of Broomrape sunflower hybrids there, and to existing sustainable hybrids parasite quickly forms a new more aggressive population. The most effective nowadays are preventive measures which make it possible to obtain high yields of sunflower and not to complicate the phytosanitary situation on arable lands in the future.
Assessment of soil clogging and seed productivity of weeds on poplar black landings
Authors: Remeniuk S. , Smolkova N.
Published: May 2020

Goal. Determination of soil contamination of plots planted for planting black poplar and evaluation of seed productivity of weeds.

Methods. The level of seed productivity of the weeds was determined by the weighting method in the following sequence. In the experiment, 10 plants of one weed species were cut and manually threshed on a tarpaulin. The purified seeds were weighed and, after determining the mass of 1000 seeds, the average amount (thousand units /plant) of seeds per plant was converted.

Results. The problem with perennial plantations of bioenergy crops is that the plants are grown for 10—15 years in monoculture on the same section of the field. Consequently, large stocks of certain weeds in the soil can significantly affect the growth and development and productivity level of cultivated plants. So, before planting a plantation, it is necessary to assess the clogging of the plots for the presence of problematic weed species, which can potentially breed on black poplar plantings and impede effective plant care. Virtually all arable land is mothballed with a different weed seed bank. Weed seed stocks depend on the direction of use of the plot, the culture of agriculture, the quality of agricultural operations on care, crop rotation, culture, etc. However, two areas with the same seed reserves in the soil are difficult to find, although the percentage of the main weed species may be identical.

Conclusions. Weeds traditionally have high seed productivity and form large seed banks in the arable soil, reaching 1.5—2.0 million units / ha. Bioenergy crops, especially perennial species, are extremely sensitive to weeds in the first year of growing season. Because they form rather modest growths of vegetative mass and can not receive photosynthetically active energy to the soil, and therefore it is important to ensure the purity of the field from weeds during the first year of vegetation.
Specificity of potential contamination of rice checks with weed seeds
Authors: Tsilinko L.
Published: May 2020

Goal. To analyze the potential level of contamination of arable soil layer weed seeds and to establish the specificity of the changes in such reserves during the vegetation period of crops. The study was performed on rice checks of the Institute of rice of NAAS in the Kherson region in the 2017—2019 biennium.

Methods. Research field, small and laboratory. To determine the factor of seeds and vegetative reproductive organs of weeds in certain soil horizons of rice fields per unit area (pieces/m2) was selected soil samples by the method of A. N. Kiseleva — twice per season, in spring and after harvest of rice. The arable soil was divided into three layers (10 cm each). To determine the viability of seeds used method of staining their tetrazoles. The results were compiled and analyzed.

Results. A comparison of the level of potential contamination between horizons showed the highest number of weed seeds in the horizon of 0—10 cm on average, 16041 pieces/ m2, which is 47.6% of the overall presence of weeds in the soil (33650,2 pieces/ m2). In the soil horizon 10—20 cm the number of weed seeds reached 10489.2 pieces/m2, or 31.2% of the debris of the upper horizon. In the lower horizon of 20—30 cm level of the presence of weed seeds was low — 7119.8 pieces/ m2, which amounts to 21.2% from that of the top horizon of the soil. Among the weed species whose seeds were present in soil samples of the top horizon of 0—10 cm, the largest part was Kuga Astrakhantseva Scirpus mucronatus L. — 59.8%, in another place Boule seeds Kuga razveseloj Scirpus supinus L. — 31.8%, Polygonum Persicaria hydropiper L. percetage — 1004.7 pieces/ m2 (6,3%), chicken millet Echinochloa crus galli L. — 329.1 pieces/m2 (2.1%). Other types were less in the stocks of weed seeds.

Conclusions. During the vegetation period inventory quantities of seeds of change and by autumn are increasing. The largest amplitude value of the stock of weed seeds is manifested in the upper 0—10 cm horizon of the arable layer and reaches to 12.3%. Qualitative and timely implementation of measures to protect rice crops from sowing to the presence of weeds provides a gradual reduction in the volumes of their Bank of seeds in the soil.
Combined effects of pesticides on weedines and seed yield of soybean crops
Authors: Hutianskyi R.
Published: May 2020

Goal. of my study was to investigate the combined effect of pesticides, including seed dressers, post-emergence herbicides, fungicides, biologicals, and plant growth regulators on weediness and soybean yield in the Eastern Forest-Steppe of Ukraine.

Methods. Field, analytical and statistical.

Results. The weeds in the soybean crops were represented by 15 species. Cockspur (Echinochloa crusgalli (L.) Roem et Schult.), yellow foxtail (Setaria glaua (L.) Beauv.), lamb’s quarters (Chenopodium album L.) and redroot pigweed (Amaranthus retroflexus L.) dominated in the soybean crops. In the controls, the dominant position in the soybean crops (in terms of the wet weight of weeds) was occupied by biennial and annual dicotyledonous weeds (56—57% of the total wet weight of weeds). Annual gramineous weeds (37—42%) and perennial dicotyledonous weeds (2—6%) ranked the second and third most spread species. Pre-sowing treatment of seeds increased the competitiveness of soybean plants against weeds. Herbicide composition Tabezon (2.0 l/ ha) + Formula (6 g/ ha) + surfactant Trend 90 (0.2 l/ ha) (primordial leaves) + Lemur (1.5 l/ ha) (biternate/ triternate leaves) significantly reduced the total number of weeds in the soybean crops by 89% and their wet weight by 97%. There was no evidence of significant effects of post-emergence combinations of herbicides with chemical or biological pesticides on the effectiveness of weed control in the soybean crops. Analyzing the soybean seed yield, I revealed that application of herbicides alone in the crops was the most justified.

Conclusions. Increased competitiveness of soybean plants against weeds on pre-sowing seed treatment has been demonstrated. There was no evidence of significant effects of post-emergence combinations of herbicides with chemical and biological pesticides on the weed control effectiveness. Monoapplication of herbicides was the most justified.

Authors: Tkalich Yu. , Shevchenko S.
Published: May 2020

Goal. The of the research was to conduct field studies of new formulations of herbicides in winter wheat crops and to optimize the phytotoxic composition of tank mixtures consisting of different-spectrum active substances.

Methods. In carrying out the work, general scientific and special research methods were used.

Results. Species diagnostics of weed phytocenoses in winter wheat crops showed that high potential weed caused dominance in the agrophytocenoses of ragweed wormwood and sunflower scavenger. The deformation of the classic wintering type of weed was observed in the direction of the annual seed species composition. The phytotoxic properties of tank mixtures of Granstar Gold and Hammer herbicides and combined preparations were studied, their technical efficiency, the dynamics of depression and the death of weeds during the growing season were established, the individual resistance of certain types of weeds was revealed. A biometric analysis (crop density, linear growth, grain yield from an ear) of winter wheat was carried out depending on the toxicity of the herbicides. The scientific conclusion was made that the most effective mixture of herbicides was Granstar Gold 30 g/ha + Hammer 20 g/ha.

Conclusions. As a result of the studies, it was found that winter wheat responded positively to reducing the degree of clogging by improving biometric and productive indicators. The yield of winter wheat grain is in a natural dependence on the degree of weediness of crops and phytotoxic effectiveness against weeds. The maximum increase in grain yield of 0.34 t/ha was achieved in comparison with the control when processing wheat crops of the winter mixture of herbicides Granstar Gold 30 g/ha + Hammer 20 g/ha.
Apera spica-venti (L.) P. Beauv. resistance to herbicides in Lithuania and Ukraine
Authors: Auskalniene O. , Zadorozhnyi V.
Published: May 2020

Goal. Check the resistance of populations of Apera spica-venti (L.) P. Beauv. to herbicides from the class of inhibitors acetolactate that are used in crops of winter wheat.

Methods. Field and laboratory studies. Visually evaluated the treatment efficacy 4 weeks after application (WAT4). Visible symptoms on the surviving plants were considered in percentage (0% — no survival, 100% plants without visible damage) to the raw options of the same population.

Results. Among the tested populations of A. spica-venti resistant to herbicides from the class of inhibitors acetolactate not detected. In all regions of Ukraine, where selected seed samples, there were repeated crops of winter wheat, and was the precursor of the culture of sunflower, soybean, lupin, etc., for control of weeds in crops which were applied the herbicides with a different mechanism of action. The reason for the low efficiency of herbicides in crops of winter wheat could be low rates of application, weather conditions, other factors associated with the technology application of herbicides.

Conclusions. Ukraine has not confirmed the resistance of Apera spica-venti (L.) P. Beauv. to the action of herbicides from the class of inhibitors acetolactate, which takes place in Lithuania. Primarily due to differences in the technologies of cultivation of winter wheat, particularly in rotations. In Ukraine, information about the presence in crops of resistant biotypes of weeds are quite limited. To prevent resistance it is necessary to conduct herbological monitoring of major crops considering the experience of countries where this problem is becoming more acute, to develop measures to prevent it.
Reliable protection of lentils against weeds
Authors: Riznyk V.
Published: May 2020

Goal. To identify the features of the infestation of crops of lentils and improve on this basis, the elements of chemical protection from adverse impact of weeds.

Methods. Field experiments were laid out in 2016—2019 according to the scheme: 1. Clogged control. 2. “Clean” control. 3. Gesagard 500 WF + Panther 4%, K. E. (3 l/ ha + 1 l/ ha). 4. Zenkor 70 WG + Targa Super, k.e. (0.6 l/ ha + 1.0 l/ ha). 5. Stomp 330, k.e. + FUSILADE Forte 150 EC, k.e. (3.0 l/ ha + 0.7 l/ ha).

Results. The contamination of crops of lentils in the years of research had mixed. As a result of pre-release areas from the presence of perennial plants (couch grass, convolvulus arvensis) weeds, mostly introduced annual grasses and dicotyledonous species. The most widespread in crops were plants of foxtail glaucous — 19.5 pieces/ m2 (22.5% in the structure of impurity), Echinochloa ordinary and 17.3 (19.9%), amaranth thrown back to 10.7 (12.3%), nightshade black — 6,8 pieces/ m2 (7.8%). In General, the time of counts (end of III decade of may) the number of weeds was 86.7 pieces/ m2. Use for protection of lentil combinations of herbicides of soil action of Gezagard 500 FW, k.s. (3.0 l/ ha) and graminicide Panther, 4% k.e. (1.0 l/ ha) reduced the ability of those present in the crops of weeds to form their mass. In average per years of research, the mass of weeds in crops of version 3 testing amounted to a total of 388 g/ m2 or 13.6% of the weedy control. Herbicides provided the reduction of the mass of weeds in 86.4%.

Conclusions. In terms of the use of herbicides of Gezagard 500 FW, k.s. (3.0 l/ ha) + Panther, 4% k.e. (1.0 l/ ha) received an average of 1.49 t/ ha of seeds, or 83.7% of the maximum in the testing of the level of harvest. Much more effective was the use Zenkor 70 WG, v.g. (0.6 l/ ha) Targa Super 5% k.e. (1.0 l/ ha) and stomp 330, k.e. (3.0 l/ ha) + FUSILADE Forte 15% k.e. (0.7 l/ ha), which provided the formation of 1.61 and 1.56 t/ ha of seeds, 90.4 and 87.6% of the “clean” control, respectively.

Authors: Klechkovskіy Y. , Mogilyuk N.
Published: May 2020

Goal. The effectiveness of the herbicides Hurricane Forte 500 SL, RK and Bast 150 SL, RK in protecting the apple orchard from ragweed was evaluated.

Methods. The studies were conducted in the field in plantations of apple trees. The soil of the experimental plot is the southern light loamy chernozem, with a humus content in the arable layer of 3.2%, pH — 7.1. The tree planting scheme was 1.5—4 m. The experiments, observations, and counting were carried out according to generally accepted methods.

Results. According to the results of phytosanitary surveys of apple plantations in farms of Odessa region, 27 species of weeds were identified, which belong to 12 botanical families. Among the annual weeds, the following species dominated: ragweed, ragweed, common shrubbery, common bedroot, white gauze; from perennial species: sharp gusset, pink sow thistle, field bindweed, wheat grass creeping, spurge vine. The mass emergence of seedlings of ragweed was observed in the third decade of April — the first decade of May. The phase of development of ragweed plants at the time of processing was 2—4 true leaves. Herbicide Hurricane Forte 500 SL in the norm of 2.0 l/ ha a month after treatment controlled 98.0%, at the end of the growing season — 83.2% of the weed. The treatment of plots with Hurricane Forte 500 SL with a flow rate of 1.0 l/ha and the addition of Trend 90 surfactant to the working solution ensured weed control after a month — 96.8%, at the end of the growing season — 80.6%. With a single application of the Bast 150 SL herbicide at a consumption rate of 4.0 l/ha, the technical efficiency a month after treatment was 94.7%; at the end of the growing season, it decreased to 60.1% due to the regrowth of ragweed plants. Two-time use of the Basta 150 SL preparation at a consumption rate of 3.0 l/ha made it possible to control the weed during the entire growing season at the level of 86.4—87.4%.

Conclusions. The use of a reduced consumption rate of the Hurricane Forte 500 SL, RK herbicide in a mixture with the surfactant Trend 90 provides control of the ragweed at the optimal rate. Herbicide Basta 150 SL, RK is more effective to apply twice.
The main weeds in the fields of the North-Eastern Ukraine
Authors: Zuza V. , Hutianskyi R.
Published: May 2020

Goal. most of the herbologists rarely classify their weeds. Some types of weeds are sometimes given only epithets. But it is necessary to divide the weeds into larger groups, and the most important thing is to determine them by their quantitative indicators and not the qualitative epithets.

Methods. Field, analytical.

Results. For 45 years the experience of crops inspection was mainly carried out in the Kharkiv region. In these years of herbological monitoring perfect methods were carried out. Previously the following prevalence groups were established: very wide, wide, moderate, small, and very small. Later another “moderately broad” group was added. In the conditions of North-Eastern Ukraine the main survey of the arable land, which lasted for several decades, has established 270 species. The weeds grouped the floral list into six parts. The analyses of the group respectively: very wide, wide, moderately wide, moderately small and very small found that the number of species was 1.9, 1.9, 4.4, 6.7, 17.3 and 67.8 percent. With the expansion of the weed list, in the group of very small weeds the percentage of species grew. In recent years some adventitious weeds have appeared. These are: four types of Abutilon theophrast Ved., Hibiscus trionum L., Diqitaria ischaemum (Schreb.) Muehl) and Phytolacca americana (L.).

Conclusions. On which territory it is necessary to determine the types of weeds and their criterion of prevalence and dominance. In the list weeds it is necessary to distinguish six groups: very wide, wide, moderately wide, moderate, small, very small. A significant part of the weeds on the list are included in the of the very small ones. In North-Eastern Ukraine, where there are 270 species observed, 67.8% of weeds belong to the last group.

ABSTRACT

Research purpose is to find out students’ problem in translating English narrative text. This research used descriptive qualitative approach and research design as a case study. Research result  were the writer found that the students had many problems in translating  narrative text. Their problem were in the form of understanding meaning such as: lexical meaning, grammatical meaning, contextual meaning, textual meaning, and socio – cultural meaning. The most problem owned by students it was  about lexical meaning because they had lack of vocabulary and they did not have a rellevant dictioanary that they would use when they translated  narrative text into Indonesian language as  target of language. The students  had difficulties in understanding about English structure that different with Indonesian structure as target of language when they did translating of  text, so, the students got confused to organize meaning. The students also had any obstacle with English pattern that was different with Indonesian pattern, when they translated, they were confused because they should change word position. Additionallay, they translated the narrative text words by words based on position of words that was appeared in  target of  language. It was also influenced by internal and external factors.
The Cohesion of the Prologue on the Hunger Games Trilogy: A Discourse Analysis
Authors: Fernandico Ann Mellene Capuy
Published: May 2020

Cohesion is designed to deal with words and phrases that generate a pattern of relations between lexical elements and structures to build an integral and logical text. The analysis of cohesion aims to connect central concepts to the context of writing intended to pursue standards of communication, writing styles, textuality, and a practice of discourse. Accordingly, this study analyzes the cohesion found in the Hunger Games Trilogy by Suzanne Collins. The method of this research is a discourse analysis focusing on Systematic Functional Linguistics (SFL) developed by M.A.K. Halliday. Based on the analysis, the prologue of The Hunger Games and Catching Fire novels can be described in the terms of field, tenor, and mode creating the contextual parameter. The text of the novels is written and is clearly detached, explicit, planned and integrated. While links were observed as characters and places were repeatedly written. The conclusion can be drawn that the two novels aim to tell a story. Furthermore, the texts do not instruct the reader on what to do but rather, it tells what the characters of the story did, are doing, or will do. The novels also implore the reader to read further beyond the prologue and to the main story.

Authors: Zuana Muhammad Mujtaba Mitra
Published: May 2020

Writing is not always easy to do. The students face some difficulties in mastering writing skill because they need particular practice to develop their writing skill. The teacher should know the students’ abilities and difficulties toward this skill and one of many ways teacher can do is by analyzing students’ compositions. In this research, they are generic structures and language features of analytical exposition texts. They may make students find some difficulties in analytical exposition texts.

This study is descriptive qualitative study and this research is aiming to describe the students’ competence in writing expository text. The researcher is the first instrument and the second instrument for this study is the students’ compositions of analytical exposition texts. To analyze the data, there will be three steps; classification, analysis, and representing to determine whether the students write analytical exposition text with proper generic structures and language features or not.

After being analysis, the researcher found that the students could write analytical exposition texts with a good generic structures and language features. However, there are some students who do not compose them properly. For generic structures, some students often do not write review of arguments in thesis and reiteration. And for language features, some of the students often do not apply the diction well. The students are proficient enough in organizing analytical exposition text in term of generic structures and language features.

From the analysis, the abilities and difficulties of the students can be identified by the teacher. The teacher should give clear explanation and understanding in teaching analytical exposition text. The teacher had to explain about how to make analytical exposition text deeply in order that the students could comprehend the text well. In addition, the English teacher could give comments to the students’ composition for the better next writing assignments, because they will know about the mistakes that they still made.

ABSTRACT

The current study aims to explore the students’ preferences on face to face corrective feedback vs online corrective feedback in ESP class. It is an attempt to investigate if they prefer to be corrected directly face to face by teachers or they like to be provided online corrective feedback by the teachers. To do so, a questionnaire was distributed to a group of students who are taking English for Specific Purposes and also focus group discussion was used in order to find out their beliefs toward their corrective feedback preferences. Totally, 50 students who were taking ESP courses at State Polytechnic of Subang participated in this study. The results from the questionnaire analysis revealed that the students preferred their teachers to use face to face corrective feedback, with an overall mean (x̄ = 3,95) in learning effectiveness, (x̄ = 4,12) in learning accuracies, and (x̄ = 4,02) in learning experiences. The focus group discussion revealed the students’ beliefs in their corrective feedback preferences, they believed that the teachers should be able to guide their learning, use communicative ways, and encourage them by using their learning preferences. The study suggested that taking these preferences into consideration could help students to increase their confidence in learning English.

Published: May 2020

Currently, Afghanistan imports a high percentage of electric energy from the neighboring coun-tries, while less attention has been paid on the utilization of internal domestic energy resources. Recently progress has been made with solar and wind energy, but other sources such as hydro energy remain underappreciated. Originally intended as a short-term solution to fulfill demand, the policy for importing power from neighboring countries is still in effect as energy demand has increased dramatically and exposed vulnerabilities in the existing power system. These issues can be categorized based on different aspects like technical, economic, political, security-related issues, natural disasters and many others that negatively affect the reliability of the energy sector. In this paper, the sustainability of the power system of Afghanistan is analyzed from different aspects. These multi-disciplinary problems are analyzed separately and linked with the weaknesses of the existing power system. The main objective of this study is to propose long-term solutions to the power sector by encouraging investment in the internal power generation to enhance sustainability and reliability. The proposed long-term solution also takes additional measures towards achieving sustainable development goals (SDG) such as economic growth, agricultural development, ground-water recharge, industrial development, flood and water control, job creation, and a green and clean environment.
