OPTIMALISASI KUALITAS AKUSTIK DI MASJID BAITUL MANSHURIN CINUNUK-CILEUNYI DENGAN METODE PENGATURAN ULANG POSISI KETINGGIAN DAN ARAH SPEAKER
Authors: Supriyadi Tata 
Published: August 2023

Kualitas akustik yang baik menjadi salahsatu syarat untuk Masjid yang baik. Kualitas akustik bisa diukur dari tingkat kejelasan ucapan (Clarity), tingkat kecukupan kekerasan suara (Sound Pressure Level-SPL) dan tingkat gema yang tidak terlalu panjang yang bisa mengganggu suara aslinya. Kondisi akustik yang kurang bagus dialami oleh Masjid Baitul Manshurin YBIBM yang terletak di Kp. Cijambe, Ds. Cinunuk , Kec. Cileunyi Kab. Bandung. Kondisi kualitas akustik yang kurang baik berdasarkan hasil observasi di ruangan Masjid lantai 1 berupa pengukuran gema ketika speaker diberi suara impulse sekitar 3 detik. Gema yang terlalu panjang ini menngganggu suara aslinya sehingga tingkat kejelasan suaranya berkurang. Selain itu berdasarkan hasil pengukuran SPL di tiap area Masjid tidak merata. Ada area yang cukup keras, ada juga area yang kurang keras dan kurang jelas. Setelah dilakukan analisis masalah ditemukan permasalahannya terletak di posisi penempatan loudspeaker yang terlalu tinggi sampai mendekati ketinggian plafon masjid sehingga suara dari loudspeaker ada yang dipantulkan oleh plafon. Sedangkan tingkat SPL yang tidak merata akibat dari arah (direction) suara loudspeaker yang kurang pas pengaturannya yang mengakibatkan suara menumpuk disalahsatu area masjid, tapi kurang di area yang lain. Metode yang digunakan untuk memperbaiki kondisi akustik tersebut yaitu dengan mengatur ulang posisi ketinggian loudspeaker ke ketinggian yang lebih rendah supaya suara pantul oleh plafon akan berkurang. Untuk mendapatkan SPL yang merata yang dilakukan adalah mengatur ulang arah loudspeaker supaya diperoleh SPL yang merata. Hasil pengukuran SPL setelah dilakukan pengaturan posisi arah speaker dapat diperoleh nilai rata-rata di setiap area sebesar 75 dB. Untuk hasil tingkat kejelasan suara setelah dilakukan dengan metode persepsi subjektif diperoleh tingkat gema menurun dan kejelasan suara meningkat dengan nilai tingkat kepuasan jamaah sebesar 89%.
Kata Kunci: optimalisasi, akustik, ketinggian louspeaker, gema, clarity, SPL, arah speaker, metode persepsi subjektif

THE BASIS FOR EFFECTIVE COMMUNICATION OF SOCIAL WORK STUDENTS IN CONDITIONS OF BLENDED LEARNING
Authors: Kotykova O. , Radchenko M. 
Published: August 2023

The article highlights the problem of ensuring the training of future social workers for effective communication in conditions of blended learning. On the basis of the analysis of scientific sources and own research, approaches to understanding the concept of "role competence" have been revealed. The role competence of future social workers is defined as an integral characteristic of the personality of a specialist in the social sphere, which has such components as role variability, role flexibility, role depth and the ability to resolve role conflicts. It is noted that the development of these components is a condition for effective communication of students majoring in social work.
An empirical study is described, the purpose of which is to determine the components of the role competence of future social workers to promote the formation of effective communication in conditions of blended learning. Both the components of role competence and the strategies of their formation are considered, namely: eagerness for new experience and the ability of the person to perform various social roles.
The relationship between formal and informal roles connected with industrial, family, social, political, and friendly relations is revealed. It has been proven that success in each of them is a guarantee of overall success and satisfaction with one's life.
An important factor of adaptation and successfulness is the ability of an individual to perform various social roles.
A necessary condition for the role competence formation is interpersonal interaction because it is in the process of communication that a person gets information about role expectations, the compliance of their own patterns of behavior with certain social statuses and roles the person performs.
It is proved that in the conditions of blended learning, important factors in the development of students’ role competence are innovative teaching methods, such as trainings, situational exercises, and role-model games, which are used by teachers in the process of their professional training.

Authors: Khrystenko O. 
Published: August 2023

The content structure of volunteering as a value regarding educational work at the institutions of higher medical education in Ukraine has been analysed in the article; the values that should be developed in future medical specialists corresponding to current challenges have been defined.
It is found out that organizational centres of public support of Ukrainians in higher medical education are the university volunteer centres, which comprehensively help the teams of students – future doctors as well as military personnel of the Armed Forces of Ukraine on the whole.
According to the results of analysis of the educational work directions in the institutions of higher medical education, it is established that they prove the highest value of human life (the life of a warrior) for future doctors from different perspectives. In particular, it is confirmed by proactive attitude of student volunteers in donating blood for military personnel.
Implementation of the value of patriotism in the educational activities of future doctors is substantiated. It is about involvement of senior students and interns into trainings on pre-hospital care.
It is established that involvement of students into projects aimed at psychological support to civilians and military personnel, as well as financial aid and assistance in supporting mental health for internally displaced persons is a special direction of medical volunteering and education in wartime.
It is proved that participation in volunteer movement by future doctors promotes development of their personal values: activity, diligence, initiative, desire to help, service, subordinating them to national, civil interests – for the sake of victory and peace in Ukraine.
Thus, educational work in the institutions of higher medical education of Ukraine requires a systematic approach to development of the values of charity and social activity in the students both regarding the volunteer movement and besides it.

Published: August 2023

Гидродинамическая прочистка канализационных сетей осуществляется службами водоканалов для поддержания сетей в рабочем состоянии и для экстренного устранения засоров. При этом используются комбинированные каналопромывочные и илососные машины с широким набором разнообразных каналопромывочных насадок. Именно от правильно подобранной насадки во многом зависят эффективность и скорость прочистки коммунальных сетей. Для устранения засоров в трубах требуется комплект насадок – как стандартных, так и специальных. В настоящее время не существует универсальных насадок, способных справиться с любым типом засора в трубе из любого материала и любого диаметра. При выборе насадки решающими факторами являются характеристики насоса каналопромывочной установки (расход воды и давление), диапазон диаметров прочищаемых труб, размеры промывочного шланга и общее состояние трубопровода. Исключительно важно также правильно определиться со спектром рабочих задач. Перед покупкой насадок рекомендуется обратиться за консультацией к специалистам.
Hydrodynamic cleaning of sewer networks is carried out by water utility services to maintain networks in working condition and for emergency elimination of blockages. In this case, combined sewer flushers and suction dredgers with a wide range of various sewer flushing nozzles are used. It is a correctly selected nozzle that is the key to the efficiency and speed of cleaning utility networks. To eliminate blockages in pipes, a set of nozzles is required - both standard and special. Currently, there are no universal nozzles that can cope with any type of blockage in a pipe of any material and any diameter. While choosing a nozzle, the determinants are the characteristics of the pump of the sewer flusher (water flow and pressure), the range of diameters of the pipes subject to cleaning, the dimensions of the washing hose and the general condition of the pipeline. It is also of utmost importance to correctly determine the range of work tasks. Before buying nozzles, it is recommended to seek the advice of specialists.

Published: August 2023

Обобщен опыт внедрения процесса ацидофикации сырого осадка на московских очистных сооружениях. На Курьяновских и Люберецких очистных сооружениях г. Москвы применены ацидофикаторы двух типов: ацидофикаторы-уплотнители и реакторы ацидофикации (смесители) с последующей промывкой и уплотнением в отдельном уплотнителе. Основным показателем для процесса ацидофикации является время пребывания по сухому веществу осадка (SRT, solids retention time). На московских очистных сооружениях оно составляло 3,5 суток, что является оптимальным значением. Было показано дополнительное образование БПК5 (увеличение в обогащенной ацидофикатом осветленной воде по сравнению с осветленной водой) от 17,8±9,1 до 31±17,5 мг/л и удельное образование БПК5 0,1 мг/мг взвешенного вещества, или 0,15 мг/мг беззольного вещества (увеличение в обогащенной ацидофикатом осветленной воде по сравнению с осветленной водой по удельному образованию БПК5 из 1 мг взвешенного или беззольного веществ, осажденных в первичных отстойниках и направленных в ацидофикатор). Выведены формулы для расчета основных технологических показателей процесса: гидравлическое время пребывания, время пребывания по сухому веществу, скорость образования летучих жирных кислот. Приведен алгоритм технологических расчетов для проектирования ацидофикаторов осадка первичных отстойников в целях интенсификации процессов удаления азота и фосфора из городских сточных вод.
The experience of introducing the process of raw sludge acidification at the Moscow wastewater treatment facilities is summarized. Two types of acidifiers have been operated at the Kuryanovskie and Lyuberetskie Wastewater Treatment Facilities in Moscow: acidifiers-thickeners and acidification reactors (mixers) with subsequent rinsing and thickening in a separate thickener. The main indicator for the acidification process is the solids retention time (SRT, solids retention time). At Moscow wastewater treatment plants, it was 3.5 days, that was the optimal value. Extra formation of BOD5 (an increase in acidificate-enriched primary water compared to primary water) from 17.8 ± 9.1 to 31 ± 17.5 mg/l and specific BOD5 formation of 0.1 mg/mg of suspended solids, or 0.15 mg/mg of ashless matter (an increase in acidificate-enriched primary water compared to primary water in specific formation of BOD5 from 1 mg of suspended or ash-free matter settled in primary settlers and sent to the acidifier) was shown. Formulas are derived for calculating the basic process indicators: hydraulic retention time, retention time as dry matter, the rate of formation of volatile fatty acids. An algorithm of process calculations for designing sludge acidifiers of primary settling tanks in order to enhance the processes of removing nitrogen and phosphorus from municipal wastewater is presented.
EVALUASI KEBIJAKAN PEMERINTAH KOTA LUBUKLINGGAU DALAM PENANGANAN MEMUTUS MATA RANTAI COVID-19
Authors: WAHYUNI HIKMAH 
Published: August 2023

The Covid-19 pandemic has not only had an impact on public health, but has also affected the economic conditions, education and social life of the Indonesian people. Based on data from the National Disaster Management Agency (BNPB), the number of positive patients infected with Covid-19 in Indonesia reached 4,114,334 positive cases of people as of December 31 2021. This pandemic has caused several local governments, especially Lubuklinggau City, to implement a Large-Scale Social Restrictions (PSBB) policy which has implications for limiting community activities, including economic activities, educational activities, and other social activities. This study uses qualitative research. Based on the results of the research, it can be concluded that effectiveness has not been maximized to be implemented. This condition can be seen by the high number of cases of people infected with Covid-19. Second, the efficiency of the policy for handling Covid-19 in Lubuklinggau City is still not related to the budget used and the lack of human resources in the process of handling Covid-19. Third, responsiveness. The implementation of the policy for handling Covid-19, the Government of Lubuklinggau City has not been very responsive to the handling of the Covid-19 pandemic. This can be seen from the slightly late Lubuklinggau City Government making regulations to prevent the spread of Covid-19, such as the recently issued Lubuk Linggau Mayor Regulation No. 31 of 2020 concerning Guidelines for the Implementation of Discipline and Law Enforcement of Health Protocols as an Effort to Prevent and Control Corona in August 2021 which in July 2020 Lubuklinggau City was categorized as a red zone, which means cases of being infected with Covid-19 are very high. Meanwhile, the first case of Covid-19 was detected in Lubuklinggau City in early April 2021.

A Robust Short Circuit Calculation Methodology for Islanded, Grid-Connected, and Utility Microgrids
Authors: Strezoski Luka , Simic Nikola , Loparo Kennet D 
Published: August 2023

<p> In this paper a robust methodology for quantifying the impact of short-circuit faults on microgrids is proposed. Microgrids can operate in both islanded (grid-forming) and grid-connected (grid-following) modes, and the ownership and responsibility for the microgrid’s operation can vary significantly: from distribution system operators to third party microgrid operators. This necessitates the development of a robust short-circuit calculation (SCC) methodology that can provide accurate results for all the possible microgrid topologies, operational modes, and ownership models. Unlike previously developed SCC methods for microgrids, the methodology proposed in this paper provides highly accurate results for all possible microgrid topologies: 1) islanded; 2) grid-connected; and 3) as a part of a larger distribution grid. In addition, the proposed methodology solves short circuit faults of any complexity, with the same simplicity. The methodology is tested on a complete model of a real-life microgrid on the Case Western Reserve University campus, operating in both islanded and grid-connected modes. The computational results show the advantages of the proposed method relative to previous SCC methods for microgrids, regarding the robustness (ability to solve complex short-circuits with an arbitrary number of faulted busses and phases, that affect a microgrid of any topology), as well as the accuracy of the results. </p>
Scaling Laws for Electromagnetic Launchers Considering an Existing Pulse Power Supply
Authors: Gülletutan Görkem , Keysan Ozan , Tosun Nail 
Published: August 2023

<p>In all areas of engineering, testing full-scale models can be both costly and risky and often not necessary. The scaling laws can be implemented in electromagnetic launchers (EMLs). The objective is to obtain similar temperatures, magnetic induction, and stress fields (T, B, and S) compared to the full-size geometry. A few EML dimensions, such as its cross-section, rail separation, and length, must be scaled appropriately to obtain accurate results. Pulsed power supply (PPS) parameters require adjustments as well. However, designing a new PPS prototype requires considerable engineering time and budget. Therefore, in this study, scaling rules are studied utilizing an existing PPS. EMFY-4, a recently developed EML with a 50 x 60 mm concave bore and 6-m length, is scaled to be used with a 250 kJ capacitive PPS. A multi-objective optimization study is conducted to get the best design. The first objective is to get a minimum rail length to seek higher energy density. The second objective is to minimize the muzzle current to the peak rail current ratio for higher efficiency. The effect of armature mass, capacitor charging voltage, and the required number of PPS modules on the objective functions are discussed. The study showed that when the existing PPS is used, the scaling with the higher scaling factor, denoted as (λ), gives better results. </p>

Why are listeners hindered by talker variability?
Authors: Luthra Sahil 
Published: August 2023

AbstractThough listeners readily recognize speech from a variety of talkers, accommodating talker variability comes at a cost: Myriad studies have shown that listeners are slower to recognize a spoken word when there is talker variability compared with when talker is held constant. This review focuses on two possible theoretical mechanisms for the emergence of these processing penalties. One view is that multitalker processing costs arise through a resource-demanding talker accommodation process, wherein listeners compare sensory representations against hypothesized perceptual candidates and error signals are used to adjust the acoustic-to-phonetic mapping (an active control process known as contextual tuning). An alternative proposal is that these processing costs arise because talker changes involve salient stimulus-level discontinuities that disrupt auditory attention. Some recent data suggest that multitalker processing costs may be driven by both mechanisms operating over different time scales. Fully evaluating this claim requires a foundational understanding of both talker accommodation and auditory streaming; this article provides a primer on each literature and also reviews several studies that have observed multitalker processing costs. The review closes by underscoring a need for comprehensive theories of speech perception that better integrate auditory attention and by highlighting important considerations for future research in this area.
