The behavior of the piles in the engineering and geological conditions of the construction water area of a new two-way pier of the berth on the territory of the sea trade port of Chornomorsk as a part of the expansion of production capacities for transshipment of grain, food products, processing of oil and grain crops was studied. During the construction, it is envisaged to use shell piles made of metal pipes 35.0...42.7 m long with the outer diameters 1020, 1220 and 1440 mm. The layers include Neogene sediments of the upper Miocene subdivision of the Sarmatian and Meotic horizons, which are represented by clayey soils from plastic to hard consistency with the lenses of silty sands saturated with the water and the interlayers of limestone. The piles cut through the sporadic layering of loams and clays, and their bottom ends are stopped in clay and dusty sands. A comprehensive approach to conducting the control tests of the piles was developed, which included conducting the tests in two stages. At the first stage, a group of four piles with the diameters 1020 and 1220 mm were tested under both static and dynamic loads at the construction site on the first supporting structures. The values of η and М coefficients, which are used to determine the bearing capacity of metal pile-shells during the dynamic tests under special geological conditions, were adjusted. At the second stage, only dynamic loads were tested on the rest of supporting structures. The inventory metal beam was as a jack pad when testing the piles with static loads, which was fixed to the anchoring piles with the welded terminations, and the movement of the head was recorded by deflection gauges. Pile driving during the dynamic load test was performed with a hydraulic hammer, which was used for their driving. According to the received data analysis of the pile test results with static and dynamic loads, it was determined that in order to obtain the values of allowable pile design loads, close to those ones determined by the static test results, it is necessary to adjust the values of η and М coefficients. It was established that for metal pile shells, which driven in the marine environment, when their bearing capacity is determined based on the results of test comparisons with static and dynamic loads, the coefficient η should be taken as 2500kN/m2, and М=1.0 – when the bottom end of the pile stopped in clay soils and M=1.6 – when in the sand.

Recently, there has been active construction development of territories with difficult engineering and geological conditions. Construction on landslide and landslide-prone slopes leads to increased loads on individual areas, which can cause activation of old or the development of new landslides. As a result of the occurrence and activation of landslides, unacceptable deformations are formed, which lead to a violation of the stability of the slope, as well as the destruction of buildings and structures. Therefore, when performing construction works on slopes, it is necessary to provide measures for engineering protection of territories, buildings and structures located on or near slopes. On many sites, the placement of slopes and the erection of supporting prisms, buttresses and counterbanks is impossible. This is due to the need to observe the limits of alienation, the presence of residential and industrial buildings. In this case, the most rational means is the installation of pile retaining structures. They are optimal for shear strength of up to 15÷20 m. If it is necessary to contain deep landslides, bored piles are exposed to large bending moments, which leads to an increase in the number of piles or their diameters. As a result, the volume of drilling work and consumption of materials increases significantly. Therefore, issues of rationalization of retaining anti-slide structures are of particular practical interest. The paper calculation models were developed and numerical modeling of the interaction of elements of two structures of retaining anti-slide structures with the soil massif was performed. Numerical modeling was performed in the licensed geotechnical software complex Midas GTS NX, which implements the finite element method. The behavior of the soil in the calculation schemes was described by the Mohr-Coulomb elastic-plastic model. As a result of calculations of the stress-strain state of the elements of the retaining structures compatible with the soil, the coefficients of the reserve of stability were determined by the reduction method and the value of the internal forces (bending moments and transverse forces) arising in the elements of the structures. The reinforcement of the retaining elements was selected for the obtained internal forces using the "SCAD" software complex. On the basis of a comparison of the costs of the main materials necessary for the construction of structures, the economic feasibility of using a landslide protection retaining structure in the form of buttresses made of bored piles has been proven.
Why Parent Together?
Authors: Hunt Marcus William
Published: July 2023

The paper offers an account of co-parenthood according to which co-parents are parent and child to one another. The paper begins by reviewing extant theories of the value of being a parent, to see whether the value of co-parenthood is reducible to this. Finding that it is not, I briefly elaborate a theory of parenthood on which parents are those who create persons. Using Aristotle’s four causes as a helpful prism, I outline how parents are the cause of their child, and how in causing a child together co-parents become parent and child to one another. For instance, since parents create children by offering themselves as models to be copied, co-parents should enjoy the best type of friendship with one another, each treating the other’s flourishing as a human person as their end. I suggest that co-parenthood contains parenthood virtually, that the co-parents’ love of their child is a manifestation of their love for one another, that the teleological fulfilled state of the friendship between parent and child exists in the friendship of co-parents.

Published: July 2023

Sport in the country is supported through program policies and is also supported in its development even with the difficulties that our society and the sports activity of the country has gone through. The management of sports clubs, federations and sports organizations in general develop their activities facing difficulties of a material nature when it comes to participation in international competitions. Therefore, this paper presents the management of money in sports organizations, infrastructure and other stakeholders. This paper is presented as a model, which has to do with the management, sports, infrastructural capacities that are at the moment, then also the distribution of the budget for federations, clubs, sports infrastructure and other organizations that perform these activities. The management of money for sports in the country has been executed for about 35 sports federations with about 867 sports clubs, where in total approximately 81.041 participate in sports activities, of which 67.583 are men and 13,458 women, and their amount spent was about 14,247,919 euro from the revenues of 18.489.005 euro that were from the country’s government. The management of money for sports in the country would open the way if appropriate measures are taken to increase the budget by engaging serious investors in terms of sports infrastructure in public- private partnerships, where this would then affect the addition of sports facilities and their management as rationally as possible where sports activities would then be increased and then this would also bring incomes. Meanwhile, sports organizations should be further supported in the operationalization of fiscal facilities for companies that are helping clubs and federations that wish to enter sports sponsorship, where this would also be pushing force in the development and improvement of sports and its conditions for the progress of sports activities.

Published: July 2023

The article describes the development of a modification of the Kolsky method used for testing brittle materials at splitting. The scheme of the experiment involves the application of a dynamic load along diametrically opposite generatrices of the cylindrical surface of the test specimen. At the same time, it is in a biaxial stressed state and fracture into two halves from the action of tensile stresses. The method is based on the assumption that the material under test behaves elastically under equilibrium deformation of the specimen. This modification is proposed to be used to determine the dynamic Young's modulus and Poisson's ratio. The derivation of relations for calculating the indicated mechanical characteristics based on Hooke's law using experimental possibilities is given. Approbation of the proposed scheme for determining elastic constants was carried out when testing specimens of fireclay brick in the Hopkinson split bar system. The deformation impulses of measuring bars were recorded with the help of tensometry to assess the forces acting on the sample and calculate the stresses arising in its center. Deformations of the central part of the specimen were determined using digital image correlation technology. The obtained graphs of stresses and strains versus time had a different time step using the optical method in combination with tensometry. The arrays of the obtained stress and strain values were reduced to a single and constant time interval up to the moment of specimen failure using linear interpolation to process the experimental data based on the derived formulas. The study made it possible to construct graphs of the dynamic Young's modulus and Poisson's ratio versus time at the initial stage of specimen loading and to determine the average values of these elastic mechanical characteristics.
KINETIC INSTABILITY IN AN ENSEMBLE OF DISLOCATIONS UNDER PLASTIC DEFORMATION OF METALS
Authors: Sarafanov G.F.
Published: July 2023

Based on a system of evolutionary equations for an ensemble of edge dislocations, the problem associated with the development of instability of a homogeneous distribution of dislocations is considered. Despite the large number of theoretical studies on this topic, most of them are considered within the framework of reaction-diffusion phenomenological models, which contradicts the mathematical structure of the initial evolutionary equations, which are hyperbolic equations. For the initial system of hyperbolic equations, the case is considered when the process of plastic deformation develops along a given axis. The elastic interaction of dislocations is neglected in order to reveal the instability features of the homogeneous state of the system due to the local kinetics of dislocations. The stability analysis of the homogeneous state was carried out for a system of dislocations of two types differing in mobility. As a result of linearization of the initial system, a system of homogeneous linear algebraic equations is obtained. From the condition of the existence of its nontrivial solutions, a dispersion equation is found, using which, on the basis of the Raut – Hurwitz criterion, the range of parameters of the initial system at which kinetic instability is realized is established. In the instability region, an expression is obtained for the increment of the unstable mode, which determines the behavior of the system beyond the bifurcation point, and an expression for the characteristic scale of the inhomogeneous structure. The region of system parameters where the diffusion dynamics of the system is realized is found. It is shown that the Turing instability for the total dislocation density is realized in this parameter range. Within the framework of the initial system of hyperbolic equations, the dynamics of both total and excess dislocation densities is significant. It is the excess density that leads to disorientation in the formation of heterogeneous dislocation structures. This is a fundamental point, since at the advanced stage of plastic deformation, the dislocation structure is basically a system of disoriented cells and ragged sub-boundaries.

Published: July 2023

The work suggests parameter differentiation method using for simplification of numerical investigation of hyperelastic soft shell static deforming problem design data parameters influence on stress-strain state of the shell. Resolving equation system is formulated in vector-matrix form. In contrast to traditional way of nonlinear problem solution continuation parameter choice, given relations are differentiated with respect to design data parameter, which influence on shell behavior is investigated. At this values of shell stress-strain state components values must correspond to some required shell operation condition, coupling investigated initial data parameter with the magnitudes of some characteristics of the shell state. So nonlinear boundary-value problem comes down to a set of interconnected quasilinear boundary and nonlinear initial problem in derivatives of resolving variables with respect to differentiation parameter, and the condition mentioned represents a relation coupling this parameter with the components of resolving variables vector. Solution of obtained set of equation systems is found sequentially by iterative way in the given parameter variation range. As an example influence of neohookean cylindrical shell fixed at end walls radius on maximum values of shell stress-strain state characteristics and their distribution along the meridian is investigated. It is found out that at radius increasing values of shell strains also increase, at this for circumferential and lateral strains there exists some radius value for which these characteristics reach extremum. For large values of cylinder radius increasing length of boundary effect zone is also typical.

Background: Evidence has emerged that altered ventricular electrocardiogram profiles are associated with dementia, but the neuropathological mechanisms underlying their associations are poorly understood. Objective: To investigate the interrelationships of ventricular electrocardiogram profiles with dementia and plasma Alzheimer’s disease (AD) biomarkers among older adults. Methods: This population-based cross-sectional study included 5,153 participants (age ≥65 years; 57.3% women) living in rural communities in China; of these, 1,281 had data on plasma amyloid-β (Aβ)40, Aβ42, total-tau, and neurofilament light chain (NfL) protein. The QT, QTc, JT, JTc, QRS intervals, and QRS axis were derived from the 10-second electrocardiogram recording. The DSM-IV criteria were followed for clinical diagnosis of dementia, the NIA-AA criteria for AD, and the NINDS-AIREN criteria for vascular dementia (VaD). Data were analyzed using general linear models, multinomial logistic models, and restricted cubic splines. Results: Of the 5,153 participants, 299 (5.8%) were diagnosed with dementia, including 194 with AD and 94 with VaD. Prolonged QT, QTc, JT, and JTc intervals were significantly associated with all-cause dementia, AD, and VaD (p < 0.05). Left QRS axis deviation was significantly associated with all-cause dementia and VaD (p < 0.01). In the subsample of plasma biomarkers (n = 1,281), prolonged QT, JT, and JTc intervals were significantly associated with a lower Aβ42/Aβ40 ratio and higher plasma NfL concentrations (p < 0.05). Conclusion: Alterations in ventricular repolarization and depolarization are independently associated with all-cause dementia, AD, VaD, and AD plasma biomarkers in older adults (age ≥65 years). Ventricular electrocardiogram parameters may be valuable clinical markers for dementia and the underlying AD pathologies and neurodegeneration.

Alzheimer’s disease (AD), the most common cause of dementia, is a chronic neurodegenerative disease induced by multiple factors. The high incidence and the aging of the global population make it a growing global health concern with huge implications for individuals and society. The clinical manifestations are progressive cognitive dysfunction and lack of behavioral ability, which not only seriously affect the health and quality of life of the elderly, but also bring a heavy burden to the family and society. Unfortunately, almost all the drugs targeting the classical pathogenesis have not achieved satisfactory clinical effects in the past two decades. Therefore, the present review provides more novel ideas on the complex pathophysiological mechanisms of AD, including classical pathogenesis and a variety of possible pathogenesis that have been proposed in recent years. It will be helpful to find out the key target and the effect pathway of potential drugs and mechanisms for the prevention and treatment of AD. In addition, the common animal models in AD research are outlined and we examine their prospect for the future. Finally, Phase I, II, III, and IV randomized clinical trials or on the market of drugs for AD treatment were searched in online databases (Drug Bank Online 5.0, the U.S. National Library of Medicine, and Alzforum). Therefore, this review may also provide useful information in the research and development of new AD-based drugs.

Published: July 2023

Because of environmental issues and energy crises, significant attention has been received in the domain of renewable and clean energy systems. Solar energy is the most effective source of renewable energy technologies. Recently, photovoltaic (PV) system have become common in grid-linked applications and plays a vital part in power production. MPPT algorithms enable PV systems to capture the maximum available power from the solar panels, regardless of variations in solar irradiance, temperature, and other environmental factors. By continuously tracking the MPP, MPPT techniques ensure that the PV system operates at its highest efficiency, resulting in increased energy harvesting and improved overall performance. Meanwhile, the frequent modifications in irradiance and temperature pose a major challenging issue which can be resolved by the use of artificial intelligence MPPT methodologies like artificial neural networks (ANN), fuzzy logic (FL), and metaheuristics systems. In this aspect, this work presents a new quasi-oppositional artificial algae optimization (QOAAO) with an adaptive neuro-fuzzy inference system (ANFIS) technique, named QOAAO-ANFIS for maximum efficiency MPPT technique for minimizing the present ripple and power oscillations over the MPP. The presented QOAAO-ANFIS model mainly depends upon the integration of the ANFIS and QOHOA techniques. In addition, the presented QOAAO-ANFIS model involves optimal MF selection of the ANFIS model to estimate the irradiation level and compute PV voltage equivalent to maximal power point. The QOAAO model can be utilized for enhancing the optimization process of membership function variables under varying conditions and awareness of global optima. The simulation result analysis of the QOAAO-ANFIS model takes place in terms of different evaluation measures. Extensive comparative results reported the better performance of the QOAAO-ANFIS model with maximum tracking efficiency of 99.89% and a minimum convergence time of 13.51 ms.
Efficient classification and preservation of log integrity through propagated chain in cloud
Authors: Sahayaraj L. Remegius Praveen , Muthurajkumar S.
Published: July 2023

Preserving the integrity of log data and using the same for forensic analysis is one of the prime concerns of cloud-oriented applications. Since log data collates sensitive information, providing confidentiality and privacy is of at most importance. For data auditors, maintaining the integrity of the log data is a prime concern. Existing models focus on providing models and frameworks that relies on any third-party entity or the cloud service provider (CSP) to handle the logs, which lacks in securing the integrity due to the presence of the external entities. Sole dependence on CSP is a major flaw together with a drawback, since the CSP itself is prone to data theft alliance. In this paper, we instantiate a mechanism which maintains the integrity of the log without compromising the performance efficiency of the system. The influence of machine learning classification techniques is leveraged in order to efficiently classify the log data before it is processed. Progressively the log data integrity is maintained through the proposed Propagated Chain of Log Blocks (PCLB), the Hybrid Vector Committed BST (HVCBST) and lightweight Multikey Hybrid Storage (MKHS) structures. The results of the implemented systems have proven to be efficient and tamper proof compared to the existing systems and can be easily rendered in any private or public cloud deployments.

Published: July 2023

Due to the dynamic nature of work conditions in the manufacturing plant, it is difficult to obtain accurate information on process processing time and energy consumption, affecting the implementation of scheduling solutions. The fuzzy flexible job shop scheduling problem with uncertain production parameters has not yet been well studied. In this paper, a scheduling optimization model with the objectives of maximum completion time, production cost and delivery satisfaction loss is developed using fuzzy triangular numbers to characterize the time parameters, and an improved quantum particle swarm algorithm is proposed to solve it. The innovations of this paper lie in designing a neighborhood search strategy based on machine code variation for deep search; using cross-maintaining the diversity of elite individuals, and combining it with a simulated annealing strategy for local search. Based on giving full play to the global search capability of the quantum particle swarm algorithm, the comprehensive search capability of the algorithm is enhanced by improving the average optimal position of particles. In addition, a gray target decision model is introduced to make the optimal decision on the scheduling scheme by comprehensively considering the fuzzy production cost. Finally, simulation experiments are conducted for test and engineering cases and compared with various advanced algorithms. The experimental results show that the proposed algorithm significantly outperforms the compared ones regarding convergence speed and precision in optimal-searching. The method provides a more reliable solution to the problem and has some application value.

With its roots in traditional advertising, digital marketing has become a specialized field over the decade preceding. Brand marketers now have a greater number of direct and indirect channels to interact with their target customers as a result of the rise in the number of personal gadgets and their use. The digital world is expanding, particularly in social media and digital marketing. As a result, many businesses decide to investigate social media and create digital marketing plans, the effectiveness of which is monitored to increase advancement. This study’s goal is to investigate the variables that affect brand-consumer relationships and digital marketing. Researchers create and estimate a conceptual model of the influences of antecedent factors (such as perceived convenience, service quality, E-WoM, brand awareness, accessibility of websites, and sharing content) on digital marketing and brand-consumer relationships by attracting hypotheses of technological advances acceptance, uses, and gratifications. Utilizing data gathered from both an established and a growing market, the researcher empirically tests the model with a consumer-centric focus (India). Results from various markets show similarities and differences between markets in terms of factors that influence customer acceptance. Researchers glean implications for hypothesis and practice from the findings. The findings indicate that perceived convenience, service quality, website accessibility, and shared content impact digital marketing. Also, it was found that digital marketing impact brand and consumer relation.
The EU’s Green Peace Narrative and Russia: Russia’s War in Ukraine in the EU’s Climate Narrative
Authors: Kovalevska Oleksandra , Braun Mats
Published: July 2023

The article looks at how Russia’s war in Ukraine enters the EU’s climate narrative. The European Union has over time developed a narrative of itself as the global green leader. This narrative has increasingly served as complementary to the EU’s foundational peace narrative. For the peace narrative, the EU’s own violent past served as ‘the other’, whereas for the green leader narrative other world powers less willing to climate action, including the US, China and Russia have served as ‘the others’.  The current war merges the two narratives and put the EU as the peaceful green leader in contrast to the brutal aggression of the authoritarian Russian oil economy. The war discourse, moreover, facilitates the concrete work with the EU’s fit for 55 climate mitigation agenda and during the second half of 2022, several important milestones were reached.
The War in Ukraine and EU Climate Leadership
Authors: Skjærseth Jon Birger
Published: July 2023

Prior to Russia’s full-scale invasion of Ukraine in late February 2022, EU deliberations on the ‘Fit-for-55’ climate/energy package embedded in the European Green Deal were already well underway. The energy transition had also begun to gain traction towards more renewables, energy saving and emissions reduction.  The invasion caused an energy-political earthquake that threatened to split the EU, slowing down or weakening these ongoing processes. This study finds that the invasion: 1) strengthened rather than weakened the ‘Fit for 55’ package; 2) accelerated rather than slowed the ongoing energy transition; and 3) may have strengthened the EU’s potential for climate leadership-by-example. However, the further consequences are highly uncertain as the EU shifts from crisis response to long-term governance of climate and energy policy implementation.

Simulation of a Radio Signal Scattered from a Rough Surface by the Method of Stationary Points
Authors: Monakov Andrey A.
Published: July 2023

Introduction. Many radar and radio navigation problems require adequate (i.e., corresponding to the physics of radio wave scattering under a certain set of conditions) simulation of a radio signal scattered from a rough surface. At present, four categories of mathematical models are used for these purposes, with each corresponding to a particular group of methods for solving the scattering problem. These methods include those based on a rigorous solution of the electrodynamic equations (methods of moments, finite elements, finite differences); approximate methods for solving electrodynamic problems (methods of small perturbations, tangent plane (Kirchhoff method), two-scale model); those of statistical equivalents; and phenomenological models. In the former two categories, the electromagnetic field is computed on a surface grid, whose step must be much smaller than the signal wavelength. This makes the simulation of a scattered radio signal effectively unrealizable for two-dimensional rough surfaces. The method of statistical equivalents is based on the calculation of the probabilistic characteristics of a scattered signal. Difficulties arising in this case narrow the possibilities of simulation, largely due to the impossibility of obtaining closed expressions for the required characteristics without significant simplifications. In addition, carrying out analytical calculations, the solution is restricted to the class of surfaces with the Gaussian distribution of roughness heights. Phenomenological models, although providing for a qualitative analysis of signal scattering from a rough surface, fail to take the physics of the scattering process into account.Aim. To create a simple and adequate model of a signal scattered from a two-dimensional rough surface using the tangent plane approximation of the boundary conditions (the Kirchhoff method), which can be realized on modern computers.Materials and methods. The proposed model of the scattered signal is based on its representation as a sum of signals reflected from stationary points on the surface, i.e., those points where the law of specular reflection of the incident electromagnetic wave is locally fulfilled.Results. The implementation of the model is reduced to determination of the positions of stationary points on a twodimensional rough surface. This problem is solved on modern computers quite simply without computations with complex numbers. It turns out that the number of stationary points, even with a large surface roughness, rarely exceeds two. This fact, along with the simplicity of finding the coordinates of stationary points, makes this model suitable for long series of statistical runs.Conclusion. The proposed model is easy to implement and can be used to study the accuracy of low-altitude target estimation, altimeters, Doppler and correlation speed and drift angle estimators.
ПОКАРАННЯ ЯК ФАКТОР ВПЛИВУ НА САМОРЕГУЛЯЦІЮ ПІДЛІТКІВ

Досліджено вплив різного строку відбування покарання в місцях позбавлення волі на саморегуляцію, соціальну фрустрацію та чутливі сторони до стимулів у підлітків. У дослідженні взяли участь 60 підлітків, котрі перебувають у Кременчуцькій виховній колонії управління Державного департаменту України з питань виконання покарань у Полтавській області – колонії для неповнолітніх ув’язнених. Так підліткова злочинність є паразитичним антисоціальним явищем, яке деструктивно впливає на правопорядок і стрімко корумпує правове суспільство. Для проведення дослідження були використані опитувальник Карвера-Уайта, методики діагностики «Стилю регуляції поведінки» В. Моросанова і діагностики рівня соціальної фрустрації Л. Вассермана у модифікації В. Бойко. Внаслідок проведеного дослідження було виявлено, що серед підлітків, які відбувають покарання до півроку спостерігається низький рівень самоконтролю, планування, спостерігається певна ригідність, головними стимулами є власне задоволення, прагнення до гедонізму і обіцяна винагорода. В той час як підліткам відбуваючим покарання два роки та більше властивий високий рівень самоконтролю, саморегуляції, чинниками впливу на них є власна терплячість і реакція на негативні стимули Саме тому пік стрімкого розвитку злочинності найяскравіше спостерігається в найбільш нестабільні періоди існування держави. Водночас рецидивна злочинність, яка активно розвивається в кризові періоди, посилює негативний вплив відповідних кризових процесів, ставить під сумнів як авторитет держави, так і засоби виховання в родині та закладах освіти. Вивчення особистості підлітків, котрі відбувають покарання в місцях позбавлення волі, є актуальним завданням, реалізація якого сприятиме вдосконаленню спеціальної політики запобігання злочинності в України, а також з метою створення тренінгів навичок саморегуляції для підлітків. Практичне значення одержаних результатів полягатиме в тому, що положення, викладені в роботі, можуть бути використані у науково-дослідній сфері – для подальшого теоретичного вивчення особи, засудженої до позбавлення волі. У правоохоронній діяльності – для оптимізації здійснення заходів із запобігання злочинним проявам; у навчальному процесі – для розробки методик, тренінгів, підручників і навчальних посібників.

Authors:   Universidad Nacional de Avellaneda, Navarro Alejandra
Published: July 2023

More than forty years ago, the cultural sector gained importance in a context of changes that resulted in transformations in socio-cultural policies. As a consequence, a process of professionalization of cultural agents began through actions, both educational and political, aimed at the consolidation of a cultural manager with specific expertise and academic training. On this line, we initiated a research (which is in its final stage) with the aim of analyzing the processof professionalization of cultural management in higher education in Argentina. From a qualitative theoretical-methodological perspective, we focused on the institutions and their members (those responsible for the coordination of careers and graduates).In this article we problematize the potentialities present in the use of various approaches to collect and construct data. The interview and the analysis of documentary sources are pertinent to achieve a deep understanding of the phenomenon to be studied. We will see how this look helps to deepen this process of professionalization of cultural management in Argentina.

The global production and consumption of plastics has been increasing continuously. However, disposing of plastic wastes in landfill is becoming undesirable due to poor biodegradability. The re-utilization of plastics together with the development of green technologies is mandatory, hence chemical recycling offers a promising alternative as a potential for plastics to maintain their original properties. The scope of this research is focused on the recycling of plastic waste by the chemical dissolution method to optimize the reaction variables in the dissolution/precipitation method using a statistical experimental design. Optimization of the recycled plastics was done using response surface methodology based on box Behnken design. The optimum yield of the recovered plastic 93.4% was achieved at a temperature of 300C, a residence period of 30min and a solvent/non-solvent ration of 1:2 v/v. The mechanical and physical properties of the recovered plastics revealed similar value to that of the virgin polymer. The FTIR spectrum of the recycled plastics shows a less significant structure alteration when compared with the spectra of the virgin polymers. Similarly, the thermal stability of the recycled plastics determined using thermogravimetric analysis (TGA) shows a less significant difference when compared with the reported thermal stability of the virgin polymers. Therefore, the study infers that chemical recycling (dissolution/precipitation) can be an appreciable option for getting rid of waste plastics in the environment as well as providing feedstock for the reproduction of plastics.

Published: July 2023

Indonesia beriklim tropis memiliki pola hujan tak menentu. Hujan adalah hasil dari sebuah proses endapan di udara yang berbentuk cairan. Terbentuknya hujan terjadi saat titik-titik air jatuh di bumi secara bersamaan. Intensitas curah hujan adalah faktor yang dapat memberi pengaruh terhadap kondisi lingkungan wilayah tersebut. Intensitas curah hujan dapat diartikan sebagai sejumlah curah hujan yang telah terkonsentrasi dan berlangsung di periode waktu tertentu, dinyatakan dengan tinggi hujan atau volume hujan ditiap satuan waktunya. Tujuan dari penelitian ini adalah mengetahui kinerja dan akurasi alat rainfall simulator apakah baik digunakan dalam penelitian tersebut, mengetahui pengaruh kenaikan sudut cakram dan tekan terhadap intensitas curah hujan, dan mengetahui klasifikasi intensitas curah hujan dengan menggunakan alat Rainfall Simulator. Hasil penelitian didapatkan nilai keseragaman untuk setiap bukaan sudut adalah lebih besar dari 70% sehingga dapat disimpulkan bahwa kinerja alat Rainfall Simulator termasuk kedalam keadaan baik sehingga bisa dipergunakan saat penelitian. Setiap kenaikan celah sudut didapatkan hasil butiran hujan yang semakin sedikit karena besarnya celah sudut dapat mempengaruhi diameter air hujan. Hasil klasifikasi yang didapatkan untuk setiap sudut 10˚, 15˚ dan 20˚ adalah sangat lebat. Jadi untuk setiap kenaikan sudut didapatkan hasil intensitas curah hujan berurut yang semakin besar.
