Authors: Relawati Rahayu , Ningsih Gumoyo Mumpuni
Published: October 2021

Produksi kentang di Kota Batu, Jawa Timur mengalami peningkatan namun tidak diimbangi dengan stabilitas harga yang diterima oleh petani, akibat dari persaingan pasar yang yang makin ketat. Tujuan penelitian ini untuk menganalisis struktur pasar komoditas kentang asal Batu di wilayah Malang Raya. Metode pengambilan sampel yang digunakan adalah purposive sampling untuk pemilihan petani kentang, dan snowball sampling untuk menentukan pedagang di sepanjang rantai pemasaran untuk mengikuti aliran komoditi kentang. Analisis struktur pasar meliputi pangsa pasar, Concentration Ratio (CR4), dan Index Herfindahl Hirchman. Hasil penelitian menunjukkan bahwa struktur pasar komoditas kentang asal Batu di Malang Raya diukur dari pangsa pasar, rasio konsentrasi (CR) dan Indeks Herfindahl Hirschman mengarah pada pasar oligopoli. Hal ini diketahui karena diperoleh nilai CR4 yang diperoleh antara 20% - 80% dan nilai IHH > 0,1. Pada struktur pasar ini petani mempunyai posisi tawar yang rendah, dengan posisi sebagai penerima harga. Rekomendasi yang diberikan untuk menaikkan posisi tawar petani adalah dengan memperpendek saluran pemasaran, misalnya dengan pembinaan petani untuk melakukan pemasaran secara online, sehingga dapat mempunyai akses langsung pada konsumen akhir. Penelitian lanjutan yang perlu dilakukan adalah menganalisis struktur pasar secara lengkap dengan pendekatan struktur-perilaku-kinerja pasar kentang dan analisis pemasaran kentang secara digital.

Hājah In Islamic Finance: Mastering The Doctrine Of Need In Sharīʿah Decision Making
Authors: Agha Ehsanullah , Zurina Shafii
Published: October 2021

Islamic financial institutions (IFIs) are compelled to operate in a highly regulated environment without jeopardizing the Sharīʿah governance framework. To deal with arising challenges, Sharīʿah decision-makers sometimes rely on the doctrine of ḥājah (need) as a device to enact a concessionary ruling. However, critiques argue that ḥājah has been used as a pretext to circumvent Islamic commercial law. This paper is an attempt to develop a possible criterion for making a legitimate need-based Sharīʿah solution for IFIs. The research concluded that a Sharīʿah vetted ḥājah can be leveraged by Sharīʿah decision-makers as a tool to address a legitimate challenge faced by individuals or corporations keeping in view the proposed parameters.
The Effect of Fossil Fuels Price on Energy’s Stock Returns
Authors: Che Roihan Nurul Syahira , Ibrahim Noor 'Adilah
Published: October 2021

Fossil fuels play an important role in energy systems as well as in the growth of technical, cultural and economic conditions of a country. In this study, we aim to investigate the effect of fossil fuels price towards energy’s stock returns in Malaysia by using monthly fossil fuels price and energy stock price taken from Malaysian Energy Commission and investing.com, respectively. To investigate their relationship, first we test the stationarity using Augmented Dickey Fuller Test (ADF). The result shows that the data are stationary at first differences. Next, we use Pearson correlation to measure the strength of the association between two variables. To observe the effect of fossil fuels prices on energy’s stock returns, we conduct a Multiple Linear Regression. We discovered that their relationships are not statistically significant. This is highly due to the competition of the use of non-renewable and renewable energy in recent years. The energy producers are adopting the renewable energy into the electricity grid which indirectly affect the utilization of fossil fuels as well as its price.

Box-Behnken Design for Optimization on Biodiesel Production from Palm Oil and Methyl Acetate using Ultrasound Assisted Interesterification Method
Authors: Mahfud Mahfud , Ansori Ansori
Published: October 2021

Energy demand is currently increasing in line with technological and economic developments, but not accompanied by an increase in energy reserves. So we need another alternative energy that can be renewed, namely biodiesel. Biodiesel has been produced commercially through the transesterification from vegetable oil with methanol using catalyst that produces esters and glycerol. The formation of glycerol which is by-product can reduce its economic value, so it needs to be done the separation process. Therefore, a new route is proposed in this study, namely the interesterification reaction (non-alcoholic route) using methyl acetate as an alkyl group supplier and potassium methoxide catalyst. The superiority of the product produced by the interesterification reaction is biodiesel with triacetin byproducts which have an economical value and can be added to biodiesel formulations because of their solubility so that no side product separation process is needed. To increase the yield of biodiesel and the interesterification rate, the ultrasound method was used in this study. To optimize the factors that affect the interesterification reaction (molar ratio of methyl acetate to oil, catalyst concentration, temperature, and interesterification time), the Box-Behnken design (BBD) is used. Optimal operating conditions to produce the yields of biodiesel of 98.64 % are at molar ratio of methyl acetate to palm oil of 18.74, catalyst concentration of 1.24 %, temperature of 57.84 °C, and interesterification time of 12.69 minutes.

The Perceptions of Roles and Understanding about Forensic Evidence and Crime Scene Preservation of Thai Paramedics
Authors: Huabbangyang Thongpitak , Kulnides Narong
Published: October 2021

Background: Paramedicine is a new profession in Thailand. The most important role is to provide pre-hospital advanced life support for emergency patients. So, they often need to assist the injured at crime scenes. However, many do not know their role or how to preserve the forensic evidence and crime scene. Currently in Thailand, their role in forensic evidence and crime scene preservation (FECSP) is unclear. Hence, the management of the evidence and the crime scene depends on individual knowledge and experience.

Objectives: 1. To study the perceptions of roles and understanding of FECSP of Thai paramedics. 2. To study the problems, obstacles, and solutions for development of Thai paramedics FECSP practices. 3. To study the factors affecting the perceptions of roles and understanding of FECSP in Thai paramedics.Method: Thai paramedics data over the country registered with National Institute for Emergency Medicine (NIEMS) during 1st March – 31st March 2021 was collected in this cross-sectional survey. The questionnaires were sent as Google forms to them by e-mail.

Results: 382 questionnaires were sent, and 281 responses (74%) were obtained. Most were female (61.9%). The average age was 26.09±4.44 years. The most common crime scene experienced was traffic accidents. Most had never had additional training related to forensic science. The perceptions of roles and understanding about FECSP were at the highest level. The most common problem and hindrance about FECSP was no FECSP law and the most common solution for improvement of the FECSP was the standard FECSP guideline development. Hospital level was found to be a factor related to the perceptions of roles of FECSP in Thai paramedics. Average score of a cohort who worked at university hospital was higher than those working at tertiary hospitals 0.220 (B = -0.220 , p-value = 0.018). Additionally, hospital level was also a factor concerning the understanding about FECSP of Thai paramedics. The average score of cohorts who worked at university hospitals was greater than those working in primary or secondary hospitals 0.197 (B = -0.197, p-value = 0.022).

Conclusion: The paramedics had the perception of the roles and understanding about FECSP at the highest level. Hospital level was a significant factor related to the perception of the roles and understanding about FECSP. Relevant health institutes should develop standard guidelines and promote FECSP training.

Authors: Thowprasert Weerayut , Orrapin Saritphat
Published: October 2021

Objective: The difficult laparoscopic cholecystectomy (LC) is defined as the presence of one of the followingconditions including prolonged operative time, conversion to open cholecystectomy or significant blood loss. Atpresent, there is no evidence of predictive factors related to longer operative time in single-incision laparoscopiccholecystectomy (SILC). The aim of this study is to determine predictive factors associated with longer operativetime in SILC procedure.Materials and Methods: A retrospective study was conducted of patients with benign gallbladder disease whounderwent SILC in Thammasat University Hospital between October 2014 and December 2020. Patients’ recordswere reviewed. Primary outcomes were preoperative predictive factors associated with DSLC. Secondary outcomeswere perioperative and 3-month postoperative adverse outcomes.Results: 592 SILC procedures were categorized as 80 DSLC and 512 non-difficult SILC (NDSLC). The median(interquartile range) of operative time in all SILC procedure is 48 (38, 62) minutes. The threshold of operative timeof difficult SILC was 72 minutes. The multivariate analysis indicated 5 significant predictive factors. Obesity (bodymass index > 25 kg/m2)) and abdominal pain reflected the difficulty of SILC procedures (p = 0.041 and p = 0.009).Calcified gallbladder showed the highest RR of 14.08 (p = 0.011). Contracted gallbladder and chronic cholecystitiswere also predictive factors with RR of 13.79 and 3.64, respectively (p < 0.001 and p = 0.007).Conclusion: Obesity, abdominal pain, chronic cholecystitis, contracted gallbladder and calcified gallbladder werepreoperative predictive factors. Surgeons should perform the SILC procedure carefully when predictive factors areidentified.

MILITARY LEADERSHIP FRAMEWORK IN TERMS OF STRATEGIC COMMUNICATIONS OF THE NATIONAL GUARD OF UKRAINE
Authors:   The National academy of the National Guard of Ukraine, Tkach P.
Published: October 2021

Fundamental documents regarding military leadership and strategic communications of the Armed Forces of Ukraine and the USA were analysed in the article. It refers to the Development of Military Leadership in the Armed Forces of Ukraine Doctrine, Project of Strategic Communications Doctrine in NGU, Strategic Communications Doctrine (AFU), Army Leadership and the Profession: Army Doctrine Publication No. 6-22, Army Leadership: Competent, Confident, and Agile Field Manual No. 6-22. Based on the analysis that was carried out, it is clarified how military leadership is viewed in the sources mentioned. Thus, Field Manual No. 6-22 �Army Leadership: Competent, Confident, and Agile� defines, that an Army leader is anyone who by virtue of assumed role or assigned responsibility inspires and influences people to accomplish organizational goals. Army Doctrine Publication No. 6-22 �Army Leadership and the Profession� specifies leadership as the activity of influencing people by providing purpose, direction, and motivation to accomplish the mission and improve the organization. In the Doctrine of development of military leadership of the Armed Forces of Ukraine approved in December, 2020 leadership is considered as deliberate influence of the personnel of different ranks during everyday, official, learning and combat activities, �nd irregular (unusual, emergency) situations on the personnel by means of maintaining trust and respect, giving purpose, directing towards achieving it, providing discipline and motivation for performing tasks as intended and improving the Armed Forces as a social establishment. It is found out that in all above mentioned documents leadership is intertwined with influence and communication that define competencies of a modern military leader. The connection of leadership with strategic communications is considered in the article. The role of command in the creation of military leadership is defined. In particular, since one of the tasks of command within strategic communications is providing leadership of the military, and leadership reveals itself in the process of using effective methods of internal communications, it has been concluded that command is simultaneously a source of creation and tool for leadership . The article states that it seems urgent to raise the question of the definition of the notion of leadership for the National Guard of Ukraine, which would make it possible to define competencies required for the NGU officers. The suggestions regarding viable definition of the notion of leadership for the further validation of the military leadership framework within the National Guard of Ukraine activity are made.
ALGORITHM FOR DETERMINING THE BOUNDARIES OF THE ZONE OF INTERFERENCE OPERATION OF THE RADIO CHANNEL OF THE UHF / VHF RANGE COMMUNICATION IN THE CONDITIONS OF OPERATION OF THE RADIOSHENOPRIAD SOURCE SYSTEM AT DIFFERENT HEIGHTS

A method for determining the limits of the maximum size of the stable radio reception area in the UHF / VHF range for mobile radio communication under the conditions of the radio interference system is proposed. The radio is intended to use a directional antenna or screen. Increasing the size of the stable radio reception area is provided by the optimal orientation at each point of the antenna device in azimuth and angle using the model of the radio channel, which allows to calculate the signal / interference ratio taking into account the spatial location of radio interference sources and digital 3D antenna pattern. receiver. The problem of determining the boundaries of the zone of stable radio exchange of mobile radio means using directional antennas in the conditions of real interference is formulated in the form of the problem of finding a single isoline in a scalar field. To determine the coordinates of the points of the map belonging to the isoline, a modification of the wave algorithm is proposed, which is low complexity and unambiguous results. Examples of practical use of the proposed numerical method allow us to conclude that the results are inconsistent with the data obtained in the known works by the analytical method for a particular case. At the same time, the numerical approach used significantly expands the possibilities of calculations by taking into account the location of multiple sources of radio interference at different altitudes, as well as the optimal orientation of the digital 3D - pattern of the antenna device of the signal receiver. The effectiveness of the proposed method is confirmed by increasing the area of the noise-tolerant radio exchange zone by 2.8 times in relation to the option of using a mobile radio with a dipole antenna. For the case of optimal orientation of the directional antenna of the receiver by the azimuth angle, additional optimization by the angle of the place gives a gain of 1.5 times.

Currently, the National Guard of Ukraine and other power structures of the state are actively working on the acquisition of subdivisions with modern weapons, including armored vehicles. For objective reasons, such work cannot be done in a short time, therefore, the BTR-70 armored troop-carrier, developed and adopted in the seventies of the last century, is still in operation in significant numbers. An analysis of the design of the armored troop-carrier indicates that its power plant has structural features that do not fully meet modern approaches to the design of such weapons and, moreover, the vehicles have practically exhausted their assigned resource. However, the experience of operating the BTR-70, including in the combat zone, testifies that the potential capabilities and maintainability inherent in its design make it possible to use the armored troop-carrier even after the end of its intended resource, although the aforementioned complicates and increases the cost of operation. One of the ways to solve this problem is the modernization of the power plant of the armored troop-carrier, in particular, the replacement of gasoline engines with modern diesel engines and the improvement of the transmission design. In the course of the study, traction and speed properties of the armored vehicle in the standard configuration and when equipped with two D245.30E2 engines and Deutz engines are calculated and estimated. As a change in the design of the transmission, the option of replacing the standard gearbox with a gearbox with an overdrive is considered. It was found that equipping an armored personnel carrier with modern diesel engines in both cases leads to a significant increase in traction properties and an improvement in the fuel efficiency of the vehicle. However, due to the fact that the crankshaft speed of diesel engines is approximately 25-30 % lower than the corresponding frequency of gasoline engines, the maximum speed of an armored personnel carrier with diesel engines is limited by the design of the transmission and is about 70 km / h. This does not meet modern requirements for machines of this type, therefore, as an option; it is proposed to install a step-up reducer (divider) at the inlet of the gearbox. In this case, it is possible to reduce the gear ratio of the transmission in higher gears and, accordingly, increase the maximum speed of the armored troop-carrier on paved roads.

EMILE DURKHEIM’IN SOSYOLOJİK YAKLAŞIMINDA SAVAŞ VE SAVAŞIN TOPLUM ÜZERİNDEKİ ETKİLERİ
Authors: ÖZMEN AKALIN Ahu
Published: October 2021

Emile Durkheim, sosyolojinin gelişimine fikirleri, görüşleri, kuramları ile büyük katkı sağlamış, kendinden sonra gelen jenerasyonlara da büyük ilham kaynağı olmuştur. Tüm toplumsal olayların özünün toplumda aranması gerektiği görüşü, Durkheim’ı sosyolojizm akımının savunucusu yapmış ve bu tür bir düşünce Ekolü’nün de gelişmesine aracı olmuştur. Her şey toplumsaldır görüşünden yola çıkarak sosyolojik kuramını geliştiren Durkheim, savaşın da toplumsal bir olay olduğunu ve toplumda önemli etkiler bıraktığını savunmuştur. Yapılan derin bir literatür araştırmasından yola çıkarak gerçekleştirilen bu çalışmada, Emile Durkheim’ın bir toplumsal fenomen olarak tanımladığı savaşın sosyolojik analizi ve savaşın toplum üzerindeki dayanışma ve vatanseverlik gibi etkileri incelenmektedir. Çalışmanın temel amacı, Durkheim’ın sosyolojik düşüncesi ekseninde, savaşın sosyolojik etkilerini incelediği çalışmaları ortaya koyarak, günümüzde üzerinde derin incelemeler yapılan bu konuların araştırmalarının 19. yüzyılın sonlarından itibaren yapıldığını ve savaş, kolektif şiddet gibi konuların birer kuramsal perspektifinin bu dönemlerde ortaya konulduğunu açıklamaya çalışmaktır. Savaşın toplum üzerinde bıraktığı en önemli etkinin vatanseverlik ekseninde ortaya çıkan dayanışma olduğunu savunan Durkheim, savaşın da diğer tüm toplumsal olaylar gibi, hem olumsuz hem de olumlu işlevleri olduğunu kanıtlamaya çalışmıştır. Özellikle, hayatının son zamanlarında savaş ve vatanseverlik konularına daha detaylı bir şekilde değindiği, bir toplumun sürekliliğini ve varlığını koruyabilmesi için vatanına sahip çıkması, dünya barışını inşa etmek için, öncelikle ulusal barışın gerçekleşmesi gerektiğini savunduğu dikkat çekmektedir. Durkheim ve kendisiyle birlikte çalışan sosyal bilimcilerin o dönemde geliştirdikleri kuram ve fikirler, günümüzde bu konular ile ilgili yapılan çalışmalarda önemli birer kaynak oluşturmaktadır.
Economic efficiency of the use of broiler chicken wastes as organic fertiliser in the spring wheat production
Authors: Shevtsova L.
Published: October 2021

This article analyzes the current state of broiler poultry in Ukraine. As a result of increasing the scale of production, the volumes of poultry waste increase proportionally. One of the promising areas increasing the sustainability of the domestic broiler poultry industry is the production of organic-mineral fertilizers, the use of which helps to preserve soil fertility and to increase the economic efficiency of this industry. To determine the efficiency of production of organic-mineral fertilizers based on chicken manure, their introduction into the cultivation of spring wheat was studied, using the following indicators: yield, production of additional products per unit area, grain costs, yield profit and the resulting level of profitability of the production chain. When investigating the dynamics of the profitability of poultry manure on the basis of statistical data, it was found that this indicator during 2016–2018 varied in the range of 5–7%. The increase in spring wheat yield (yield profit) was analyzed, as this indicator is the primary factor determining the level of profitability of the production chain. The efficiency of the use of chicken manure fertilizers in comparison with traditional organic fertilizers is confirmed by the increase of spring wheat yield by 12–24%. It was proved that the optimal dose of chicken manure fertilizers is a dose of 5–7 t/ha. Thus, in the cultivation of spring wheat, such fertilizers are a low-cost and resource-saving element. Given that the current state of Ukrainian agriculture is mainly determined by its poor economical state, the use of wastes of the broiler industry (manure and possibly also litter) is a promising way to make this industry sustainable and to enhance agricultural production with cheap and in principle environment-friendly fertilizers. It is concluded that the production of organo-mineral fertilizers from chicken manure as a by-product of animal origin is a relevant, economically feasible, effective and promising way in agriculture in the current socio-economic situation, because it allows to preserve and improve soil fertility and increase economic efficiency of poultry production.

Authors:   National Transport University, Sokolenko Tetiana
Published: October 2021

The main types of maneuvers on crossings and adjoints of highways in one level are studied. The probability of an unobstructed injection of a vehicle from a secondary to the main road and vice versa, taking into account the average length of the free interval between the vehicles of the main stream, is determined. The dependence of the duration of free intervals, and their number, on the intensity of traffic, the composition of the traffic flow, and the speed of vehicles, was found. A series of equations was obtained for determining the total transport delay in the performance of various types of maneuvers, depending on the type of intersection or adjacency. Vehicle delays at crossings and adjacent roads are used to economically justify changing their parameters. Therefore, the work is designed to minimize the delays of vehicles at crossings and interconnections both in one and at different levels.

FLOTATION OF LEAD-ZINC ORE USING A MIXTURE OF DITHIOCARBAMATE AND XANTHATE
Authors: Konovalov Ivan A.
Published: October 2021

The collecting capacity of xanthate, dithiocarbamate and their combination was studied. The effect of activity with respect to the gas-liquid interface of derivative forms of reagents represented by physically sorbed forms of collector was considered. Flotation experiments of lead-zinc ore from the Gorevsky deposit showed an increase in flotation performance when using reagent combinations. The use of a collector with pronounced chemisorbable properties in combination with a reagent having surface-active properties towards the gas-liquid interface caused an increase in the recovery of useful component. It was determined that activity of the physical form of sorption affects the selectivity of lead and zinc recovery - as activity of the physically sorbed form of reagent decreases, the selectivity of recovery grows.

Published: October 2021

Creation of downhole sources of elastic vibrations for the implementation of vibrowave enhanced oil recovery methods is an urgent task of mining engineering. The paper substantiates the expediency of using an electromagnetic linear drive of a downhole vibration source to generate axial shock pulses. A mathematical model is proposed that describes the dynamics of movement of the striker of electromagnetic impact unit under the action of traction forces of coils, friction forces and aerodynamic resistance, taking into account the elastic constraints at the end of the lower and upper working strokes of the striker. Theoretical dependences of striker displacement and speed on time, obtained using the developed model, are presented, and their high convergence with the experimental data is shown. The mathematical model of electromagnetic impact unit can be used to optimize its parameters, as well as to design new standard sizes of vibration sources that meet the requirements of the oil and gas industry.

The paper presents the results of measurements in 2019 by electrotomography at the site of the emplacement hole of the peaceful underground nuclear explosion "Crystal", carried in 1974 at a depth of 98 m in permafrost Cambrian carbonate rocks, and the neighboring forest area. The fence made of metal poles and barbed wire around the site, and the buried fragments of the casing of the emplacement hole create significant interference of measurements. To avoid the electromagnetic noise, the measured data of the apparent electrical resistivity was cleaned manually. Data inversion was performed in the Res2Dinv program. Geoelectric models, namely two-dimensional sections of the upper part of the geological environment to a depth of up to 80 m, were obtained. To verify the models, forward modeling was performed using the ZondRes2D program.

Refracted waves are often used in neat-surface exploration. A limited observation system in the form of unidirectional profiles is often used. In our work, we selected an object with a known anisotropic upper part of the cross-section. The results of refracted waves processing show the anisotropy of one of the layers of the medium, the azimuthal anisotropy of which led to the observation that the refraction on its top ceases from the first arrivals, for the direction of the profile aligned with the axis of symmetry of the azimuthally anisotropic layer.

Authors: Chanyshev Anvar I. , Belousova Olga E. , Luk’yashko Olga A.
Published: October 2021

The authors discuss bursting of barriers by solid bodies. The resistance function changes along a single-arc sinusoid. The equation of motion of a solid body is solved. The velocity of the drift hammer to reach the back of the barrier is determined. The alternative initial velocities such that the solid body is jammed in the barrier or is shot outside the barrier are examined. Determination of the barrier resistance force versus the shoot-out velocity of the drift hammer is discussed.
FEATURES OF PROPAGATION OF HYDRAULIC FRACTURES IN STRATIFIED ROCK MASS
Authors: Sher Evgeny N.
Published: October 2021

In hydraulic fracturing commonly used in mining, it is important to determine the shapes and sizes of created fractures. The governing factor in this case is the structure of rock mass which is often stratified. This study analyzes the influence of strengths of the layers and their stress states on the shapes of the growing fractures. Numerical modeling shows that in hydraulic fracturing with low-viscous fluids, fractures grow mostly in a layer having lower tension or compression strengths. The calculations carried out for the analyzed cases provide the values of tension strength and external compression for hydraulic fractures to grow only in one layer. It is shown that the increase in the breakdown fluid viscosity weakens this effect.

DESIGNING ANNULAR ELASTIC VALVE THAT CONTROLS AIR EXHAUST FROM WORKING CHAMBER OF PNEUMATIC IMPACT MACHINE
Authors: Primychkin Alexander Yu.
Published: October 2021

The paper considers one of the promising shut-off and control elements of the air distribution system of pneumatic impact machines - an annular elastic valve (CUV). This element allows you to reduce the energy consumption of pneumatic devices. Unfavorable combinations of factors that hinder the movement of the valve necessary for sealing the working chamber are considered. The paper presents a method for calculating the elastic valve that controls the release of energy from the return chamber of the pneumatic impact machine, which allows determining the main geometric dimensions of the valve device at the design stage, which provides a stable self-oscillating cycle of the pneumatic impact machine with the specified energy characteristics. The developed technique was used in the modernization of the air distribution system of the ring impact machine (KUM), designed for immersion of rod elements in the ground. Tests of the resulting sample in production conditions confirmed the increase in energy performance compared to previously produced machines of a similar type.
