Authors: МУНТЯН Стелла , СПАССКОВА Олена
Published: June 2024

Пленерне освітлення для художника має велике значення. Саме на пленері художник збагачує свою палітру, роблячи її більш чистою й різноманітною. Розвиток просторового мислення, передача світло- сприйняття повітряного середовища, цілісності та узагальненості, що переходить в умовність, – основні завдання роботи над сюжетною композицією в умовах пленеру. Специфіка пленерного живопису потребує переосмислення основ зображення з урахуванням світлоповітряного середовища. Основою професійного становлення митця є розвинене творче мислення, вміння цілісно сприймати та зіставляти побачене з образами, що формуються в уяві, а також співвідносити цей умоглядний образ із композиційною побудовою на площині. Важливе значення в цьому процесі приділяється пленеру. У реальному світі художник знаходить не лише образи своїх картин, а й основу для композиційної побудови. Упевнений та виразний малюнок, звучний колорит, вільне володіння технікою – це основа на шляху до мистецтва живопису. Мета статті полягає у виявленні основних питань, які виникають під час створення сюжетної композиції при пленерному освітленні. Методологія. Використано історико-хронологічний та формально- стилістичний методи, які передбачають системне опрацювання матеріалу, його порівняння та синтез. Наукова новизна. Було проведено аналіз історії, теорії та методики створення художнього образу в сюжетній композиції в умовах пленеру, вивчено досягнення українських та зарубіжних художників у цій галузі. Висновки. Хоч би які зовнішні чинники впливали на зображуваний образ, загальний тон освітлення поєднує все різноманіття фарб пленерного живопису в загальну колористичну єдність. Знання всіх особливостей пленерного живопису допомагає збагатити та розширити практичні вміння та навички при створенні сюжетної композиції, зібрати творчий матеріал з новими образами та ідеями для майбутніх мистецьких робіт.

Published: June 2024

Мета статті – аналіз українського мистецтва початку 20 ст. як чинника формування етнокультурного простору. Методологія дослідження базується на основних положеннях загальнонаукових методів аналізу, синтезу, узагальнення. Культурологічний підхід дає можливість трактувати мистецтво як феномен культури. Аксіологічний підхід ґрунтується на розумінні мистецтва як феномену культури, що має ціннісний статус. Наукова новизна. Вперше показано, що українське мистецтво початку 20 ст. було вагомим фактором формування та збереження етнічної ідентичності, впливало на формування національної свідомості, сприяло формуванню етнокультурного простору України. Висновки. Етнокультурний простір як вияв унікальної культурної спадщини народу, що включає мову, мистецтво, традиції, звичаї, релігію, освіту, науку тощо, допомагає людині розуміти своє походження, ідентичність, історію, цінності. Етнокультурний простір забезпечує розвиток спільних цінностей, які об’єднують членів національної спільноти, сприяє формуванню національної свідомості, історичної пам’яті, патріотизму, національної гордості. Початок 20 століття був періодом значних соціально-політичних змін в Україні, які суттєво впливали на розвиток культури. Мистецтво за цих обставин виконувало особливу етноформувальну роль та сприяло формуванню етнокультурного простору України. Показано, що мистецтво є вагомим фактором формування та збереження етнічної ідентичності, має значний вплив на формування національної свідомості, оскільки воно акумулює національні цінності, ідеали, уявлення про історичне минуле і цим сприяє утвердженню культурної самобутності. Українське мистецтво початку 20 ст. є важливим здобутком національної культури, воно сприяло відродженню та утвердженню української культури, значною мірою впливало на формування національної свідомості та ідентичності, формуючи український етнокультурний простір.

Critical Queer Analysis of Normative Discourse
Authors: Ilham EL MAJDOUBI
Published: June 2024

This article presents a preliminary socio-historical reflection on Queer Theory, exploring how this critical perspective challenges conventional notions of sex, gender, desire, identity, discourse, ideology, and power. Moreover, the article considers how Queer Theory offers insights into the study of theater as an art of the margins, in particular discursive dramatic counter-strategies. The study indicates that theater from the Augmented Age draws upon concepts derived from Queer Studies. Modern and contemporary Western plays engage with transgressive sexual topics in innovative ways, challenging traditional stereotypes about sexuality. The study also poses the question of whether theater is still oriented towards societal acceptance and concludes that it is undergoing a revolutionary transformation.
Análisis teleológico de la prueba indiciaria y su relación con las capturas de pantalla de Whatsapp en Colombia
Authors: Vélez García Yiseth Paola , Tejeda Morales Yurleidys María , Correa Fernández Marlon de Jesús
Published: June 2024

La mensajería instantánea se ha convertido en una actividad cotidiana y relevante en la vida de las personas. No obstante, en el desarrollo de estas relaciones digitales, se presentan aquellas con interés jurídico, para lo cual se hace necesario la aportación probatoria a un proceso judicial, siendo el medio más utilizado el de las capturas o pantallazos. Sin embargo, dicha relevancia al interior de la litis, puede que no sea tan destacada, en el entendido que su valor probatorio ha venido siendo modificado por parte del máximo organismo de la jurisdicción constitucional, esgrimiendo en algunos apartes que estas deben de ser valoradas de conformidad con la comunidad de pruebas y no de manera directa, postura que se desprende de los pronunciamientos dados por la Corte Constitucional, al catalogarlas en su momento como indicios. Por lo tanto, el presente artículo tiene como objetivo, determinar las repercusiones subyacentes de los recientes pronunciamientos de la Corte Constitucional, frente a la categorización de la prueba indiciaria respecto de las capturas de pantalla de aplicaciones de mensajería instantánea. Para dicha finalidad, se utilizó un método analítico de investigación con el objetivo de analizar las repercusiones que se desprenden de la categoría de indicio sobre estos pantallazos, permitiendo con ello la generación de una hipótesis con relación a esta postura jurisprudencial. Por esa razón, fue posible concluir que la postura que subyace de las recientes decisiones de la Corte Constitucional ha redundado negativamente en el Derecho Probatorio Digital con relación a las capturas de pantalla de aplicaciones de mensajería instantánea como WhatsApp, al determinarlas como prueba indiciaria, limitando con ello su valor probatorio y colateralmente su incidencia directa en la verdad real y judicial que se busca en el proceso.
SNAKES AND LADDERS GAME AS A SOLUTION TO REDUCE STRESS BY PARENTING STYLE AS A MEDIATION IN MATHEMATICS SUBJECTS
Authors: Hasibuan Wilda Fasim , Qoriaturrosyidah Fitri , AlWahab Putri Annisa , Ananda Nur Fitri , Hanggara Yudhi
Published: June 2024

Stress in everyday life is normal, but it becomes extraordinary when it occurs during adolescence. There are numerous stressors for adolescents, including academic success in mathematics. Consequently, the purpose of this study is to provide education on snakes and ladders as a means of reducing stress tendencies by mediating mathematics parenting. Before receiving the ladder snake educational treatment, there was no difference in stress tendencies (p < 0.152). Then, regardless of their parenting style, the level of student tension is the same. The inference is that lowering stress tendencies in adolescents cannot be achieved by concentrating on a single causal factor; rather, it is required to look for additional elements that broadly impact stress.

ABSTRACTThe mangulosi ritual is part of the ulaon unjuk ritual ceremony in Toba Batak marriages. This research analyzes the performativity of the mangulosi ritual based on an "is" performance perspective. The method used is qualitative with a theater anthropology approach. The results showed that the mangulosi ritual is a spectacle that allows active interaction between the presenter and the audience. The historical condition of the culture of the Toba Batak people who do not have performing arts performances outside of traditional ceremonies, so traditional ceremonies become one of the places to watch performances. As a performance continuum, the mangulosi ritual has some basic similarities with theater. These similarities are that it has a specific time, gives symbolic value to objects, is non-productive, has certain rules, and is often held in special places. It can be a limitation of the mangulosi ritual event ("is") a performance that has similarities with theater referring to the cultural context of the Toba Batak community. Keyword: Mangulosi, Performativity, Theater Anthropology, Performance ABSTRAKRitual mangulosi merupakan bagian dari upacara ritual ulaon unjuk dalam perkawinan masyarakat Batak Toba. Penelitian ini menganalisis performativitas ritual mangulosi berdasarkan perspektif “adalah” pertunjukan (“is” performance). Metode yang digunakan adalah kualitatif dengan pendekatan antropologi teater. Hasil penelitian menunjukkan bahwa ritual mangulosi merupakan sebuah tontonan yang memungkinkan interaksi aktif antara penyaji dan penonton. Hal tersebut didukung oleh kondisi historis budaya masyarakat Batak Toba yang tidak memiliki seni pertunjukan yang dipergelarkan di luar upacara adat, sehingga upacara adat menjadi salah satu tempat untuk menyaksikan pertunjukan. Sebagai salah satu kontinum dari performance, ritual mangulosi memiliki beberapa persamaan dasar dengan teater. Beberapa persamaan tersebut adalah memiliki waktu tertentu, pemberian nilai simbolik pada objek, bersifat non produktif, memiliki aturan tertentu, dan kerap diselenggarakan di tempat-tempat khusus. Hal tersebut dapat menjadi pembatas peristiwa ritual mangulosi adalah pertunjukan (“is”) performance yang memiliki persamaan dengan teater mengacu pada konteks kebudayaan masyarakat Batak Toba. Kata kunci: Mangulosi, Performativitas, Antropologi Teater, Pertunjukan

High rate of morbidity and mortality may result from NSA if left untreated. Majority of NSA cases in developing countries present themselves late at the health care facilities, making the diagnosis difficult and sometimes overlooked by health care providers. Although septic arthritis has already been investigated but cases of NSA from developing countries are under reported. The goal of the study was to better understand the clinical and microbiological characteristics of neonates with septic arthritis as well as their prognosis of treatment.  This prospective observational study was conducted in Neonatal Intensive Care Unit (NICU) of Department of Neonatology and Out Patient Department (OPD) of Orthopaedics, Banga bandhu Sheikh Mujib Medical University (BSMMU). Total 30 neonate presented with acute septic arthritis were included in this study. Data were collected by reviewing record from NICU and   disease course, investigation profiles, treatment record of neonates were noted as recorded during the time of hospital stay or attending in OPD. For the assessment of prognosis clinical and radiological findings of all cases were followed-up for 12 months of age. Collected data of neonates with septic arthritis from record review were processed and analyzed by Statistical Package for the Social Sciences (SPSS) and result of analyzed, finally data were presented as in tables and graphs. This study finds that  nearly two-third (63%) of the neonates were male and knee joint was most frequently involved, accounting more than two-third ( 67%) of all single joint involvements. All of the cases were anemic and had high C-reactive protein (CRP) level.  Joint aspirate samples culture showed that the most prevalent (41%) organism was Klebsiella, followed by Acenotobacter and Seratia. Gram-negative bacteria predominated (91%). Most of the patient (76%) had favorable prognosis after treatment. Clinical evaluation and start of intravenous antibiotics should be given priority in suspected cases. Prompt surgical intervention and consistent follow-up in a tertiary hospital are necessary for the best results.

Authors: Ambarwati Zaneta , Jafar Jafar
Published: June 2024

In the construction world, there are several ways to connect reinforcement: lap splice, welding, and mechanical. This study compares the flexural performance of reinforced concrete beams where the reinforcement is connected by lap splice and mechanical threaded coupler type. The size of the reinforced concrete beam used as the test object is 200×300×2000 mm, with an f'c value of 25 MPa. Three test specimen beams were prepared in this study: beams without reinforcement joints beams with lap joints, and beams with mechanical joints. From the laboratory tests, the nominal moment values (Mn) for reinforced concrete beams with lap joints and mechanical coupler-type connections were 42.231 MPa and 29.436 MPa, respectively. The maximum load is on the beam with lap joints of 138.85 kN. From the nominal moment value and maximum load obtained, it can be seen that the beam with lap joints can bear the most significant load. Regarding ductility, beams with coupler connections tend to be more brittle (non-ductile) when compared to beams with lap joints. Therefore, although the coupler-type mechanical connection has benefits, it has yet to be able to replace the lap joints in reinforced concrete beams in terms of strength and ductility. Mechanical connection failure occurred in the reinforcement section, which was turned to connect with the coupler.ABSTRAKDalam dunia konstruksi terdapat beberapa cara untuk menyambung tulangan yakni dengan cara penyaluran lewatan (Lap Splice), pengelasan (welded), dan mekanis. Penelitian ini membandingkan kinerja lentur balok beton bertulang dimana tulangannya disambung dengan cara penyaluran lewatan (Lap Splice) dan mekanis tipe threaded coupler. Ukuran balok beton bertulang yang digunakan sebagai benda uji adalah 200×300×2000 mm dengan nilai f’c 25 MPa. Tiga balok benda uji disiapkan dalam penelitian ini yakni, balok tanpa sambungan tulangan, balok dengan sambungan lewatan, dan balok dengan sambungan mekanis. Dari pengujian laboratorium yang dilakukan didapatkan nilai momen nominal (Mn) untuk balok beton bertulang dengan sambungan lewatan dan sambungan mekanis tipe coupler berturut-turut sebesar 42,231 MPa, dan 29,436 MPa. Beban maksimum terdapat pada balok dengan sambungan lewatan yakni sebesar 138,85 kN. Dari nilai momen nominal dan beban maksimum yang diperoleh dapat dilihat bahwa balok dengan sambungan lewatan dapat menanggung beban terbesar. Dari segi daktilitas, balok dengan sambungan coupler cenderung lebih getas (tidak daktail) jika dibandingkan dengan balok dengan sambungan lewatan. Oleh karena itu, meskipun sambungan mekanis tipe coupler memiliki benefit, namun belum mampu menggantikan sambungan lewatan pada balok beton bertulang dari segi kekuatan dan daktilitas. Kegagalan sambungan mekanis terjadi pada bagian tulangan yang dibubut untuk keperluan penyambungan dengan coupler.

One of the harmful effects of limited green space is high air pollution. As many as 7.78% of residents who live in East Jakarta suffer from ISPA. This problem can be overcome by building green open spaces around settlements. This study aims to analyze and evaluate green open spaces located in the Pulogadung Industrial according to the Minister of Industry's regulation towards the green-blue open space concept. The method used in this research is descriptive quantitative. The results of this study are that the Pulogadung industrial area has land that functions as a green open space of 30.49 hectares, or around 6% of the entire area. Based on the Minister of Industry regulation, a minimum green open space is 10% of the total area. It proves that green open space in the Pulogadung industrial area must meet the assessment criteria. The Pulogadung industrial area has green-blue open space. However, it does not fulfill the green-blue open space concept according to the ATR/BPN ministerial regulations in terms of fulfilling socio-cultural and aesthetic functions because it does not provide recreational facilities, and tree planting does not show a symmetrical pattern.

Kluwak shell carbon (KTK) is a biomass with potential as an adsorbent, containing cellulose, hemicellulose, lignin, and fixed carbon at a content of 92.15%. However, the current utilization of KTK in adsorbing free fatty acids and methylene blue is limited and can be improved through thermal activation at a range of temperatures. The study aims to investigate the impact of activation temperature on CEC by examining the adsorption capacity of methylene blue solution, iodine solution, and surface area. Activation was carried out for 2 hours at temperatures ranging from 500 to 900 C on Kluwak shell carbon. The adsorbent performance of the activated KTKAT was initially tested using methylene solution with a concentration of 50 ppm, a volume of 50 ml, and 0.15 grams of KTKAT. The solution was placed in an orbit shaker for 90 minutes and filtered. The absorbance of the filtrate adsorption results was measured at a wavelength of 662 nm using UV VIS. For the second test, 50 ml of 0.1 N Iodine and 0.5 g KTKAT were stirred for 15 minutes and then centrifuged for approximately 15 minutes. A volume of 10 ml of the resulting iodine solution adsorption filtrate was titrated with 0.1 N Sodium Thiosulfate. The surface area was determined using the BET method. The concentration (ppm) of methylene blue solution was determined by converting the absorbance measurement using the standard curve equation. The iodine number was determined by titrating the iodine adsorption filtrate with sodium thiosulfate (ml). These data show that there is an obvious correlation between activation temperature and methylene blue absorbance, iodine number, and surface area. At 800°C, the methylene blue adsorption is 12.41 mg/g, the iodine number is 875.61 mg/g, and the surface area is 561.404 m²/g.

Ring of Fire and at the intersection of three tectonic plates. Efforts are needed to minimize earthquake damage, one of which is the use of a base isolator system. This study aims to determine the effect of using High Damping Rubber Bearing (HDRB) with a diameter of 800 mm on the behavior of reinforced concrete structures in tall buildings under seismic loads. The research location is the 7-story Sapadia Hotel building in the city of Mataram. The research is conducted by analyzing a 3D model of the fixed base structure and the base isolator structure using numerical analysis. The results show an increase in the base displacement of the base isolator structure by 59% in the x-direction and 44% in the y-direction, while the inter-story displacement decreases by 36% in the x-direction and 69% in the y-direction. The use of base isolators can reduce the shear force by 35% in the x-direction and 15% in the y-direction. Based on the pushover analysis, the roof displacement values for the fixed base and base isolator structures are 0.159 m and 0.129 m respectively. These values can be used to determine the structural performance level according to ATC-40. The maximum drift value for the fixed base structure is 0.0055 m. For the base isolator structure, the maximum drift value is 0.0044 m, categorized as Immediate Occupancy (IO). This value can be used to determine the performance level of the structure based on ATC-40. The maximum drift value of the fixed base structure is 0.0055m. While in the base isolator structure, the maximum drift value is 0.0044 m which is included in Immediate Occupancy (IO). Thus, the use of base isolators in high-level buildings is able to reduce post-earthquake damage and the building is still safe to continue using.

Berenuk fruit (Crecentia Cujete L) is a non-food plant often found in tropical areas. Berenuk has quite a high content of carbohydrates and its derivatives. Among them are 18.61% carbohydrates, 59.86% sucrose, 25.09% fructose, and 18.24% galactose, so berenuk fruit has the potential to be a source or ingredient for bioethanol. The bioethanol process from biomass goes through several steps: raw material preparation, hydrolysis process and fermentation. The hydrolysis process is the process of breaking down carbohydrate into glucose units which are connected by β-1,4 glycosidic bonds. Another method of breaking sugar polymers can be done using alternative energy such as ultrasonic waves (50Hz, 50W) or microwaves. In this research, an ultrasonic-assisted acid hydrolysis process was carried out. The type of acid used is concentrated sulfuric acid (H2SO4). Ingredients ratio 1:20 (w/v) berenuk powder sample with sulfuric acid. The sulfuric acid concentrations used were 1 M, 2 M, and 3 M. Hydrolysis times were 40 minutes, 60 minutes, and 80 minutes at a temperature of 1000C. The results of research that has been carried out on the preparation process of bereneuk fruit have an average water content of 97.44%, so treatment is required before proceeding to the hydrolysis and fermentation process, namely by drying the drying process is carried out directly in sunlight for seven days, then continued by heating the oven for 8 hours at 1000C. In the ultrasonic wave assisted hydrolysis process carried out at a H2SO4 concentration of 3 M, a hydrolysis time of 80 minutes, and a temperature of 1000C produces 22.20% glucose.

Published: June 2024

The Batanghari 1 Bridge serves as a vital link connecting Jambi City and Muaro Jambi Regency. Currently, the traffic density at the Batanghari intersection is notably high, particularly during peak hours, resulting in frequent traffic jams. To address this issue, the Perencanaan dan Pengawasan Jalan Nasional (P2JN) and Planning Consultants executed a Detailed Engineering Design (DED) Planning for the Duplication of the Batanghari 1 Bridge in 2021. The Duplication DED transformed the original intersection into a combination of an intersection and a U-turn. However, a notable challenge emerged during rush hours, especially for Jalan KH.A. Majid, where a U-turn is essential to cross the Batanghari Bridge. In this study, a traffic microsimulation was initiated at the Batanghari intersection. Using PTV Vissim software, microsimulations were conducted under three scenarios: Existing Condition, Detailed Engineering Design (DED), and an Alternative scenario, which involved incorporating a Flyover for KH.A. Majid Road towards Batanghari Bridge. Furthermore, traffic microsimulations were conducted to anticipate conditions over the next two decades. The analysis involved microsimulation using Vissim software, encompassing calibration, trial and error validation of the intersection model considering driver behavior, and GEH tests on traffic volume. The microsimulation results at the Batanghari intersection revealed that the alternative model effectively reduced queues, minimized delay times, and improved overall travel time compared to the proposed model.
