The purpose ofthis research is to obtain the maximum and minimum irrigation water demand discharge in the study area. This research can be an additional source of knowledge for writers in particular and for readers in general. As well as the results of this study can be known the value of rice planting water needs. The data used in the research is rainfall data sourced from BMKG (Meteorology, Climatology, and Geophysics Agency) Malikussaleh, used to calculate effective rainfall and climate data sourced from BMKGMalikussaleh in the form of temperature data, solar irradiation data, wind speed data and humidity or temperature data used to calculate evapotranspiration (ETo). ETo is a combination of evaporation and transpiration which is defined as the event of water loss from plant tissue and the surface of the soil usedas a place to grow plants. In analyzing ETo using the Penman Modification Methodology. The Penman method by adjusting the wind function according to local conditions produces the best approach to the evapotranspiration rate of the lysimeter results. The consumptive use of plants (ETc) during the land preparation period uses the results of the calculation of water requirements for land preparation (IR). Crop consumptive use (ETc) after land preparation is a calculation between evapotranspiration and cropcoefficient. The calculated irrigation water requirement (NFR) results in water requirement in the form of mm/day. Irrigation water requirements are converted to l/dt/ha with a conversion rate of 1/8.64. The smallest water demand calculation discharge was obtained in November-1 at Q = 4.32 m3/det and thelargest water demand in February -1 at Q = 13.40 m3/det.

Lathe machining is one type of conventional machine tool used for cutting/filling workpieces which is done by making an incision on the workpiece where the tool is moved translationally and parallel to the axis of the rotating workpiece. The result of the components of the turning process that is commonly done is surface roughness which is influenced by tool cutting angle, feeding speed, cutting speed, depth of cut. This study was conducted to determine how much influence the speed of feeding and depth of feeding on AISI 1045 steel and AISI 4140 steel materials used in shafts, conecting roads, gears with carbide chisels. With Vc=140 m/min, Vc=150 m/min, Vc=170 m/min, and Vc=180 m/min, and knowing the surface roughness of the workpiece using a carbide tool.  From the results of research on AISI 1045 and AISI 4140 steel for cutting along 50 mm with engine speed 1200 rpm and cutting depth 0.3 mm, as well as the cutting speed used Vc=140 m/min, Vc=150 m/min, Vc=170 m/min and Vc=180 m/min and the initial cutting distance of 4 mm, the time needed is 1,125 minutes. For the surface roughness value of AISI 1045 steel material and AISI 4140 steel has four variations in lathe feeding speed in this study, which in each variation has a different surface roughness value, the smallest surface roughness value is AISI 4140 steel with a feeding speed vc = 180 m / min surface roughness value of 0.705 μm compared to AISI 1045 steel material. This is due to the greater the movement of the feeding speed of feeding, the smaller the value of the surface roughness of the material

Honeycomb is applied to the Open Series Subsonic Wind Tunnel which aims to obtain a unidirectional fluid flow shape with uniform (laminar) and stable fluid flow velocities. Honeycomb testing was carried out experimentally at a flow velocity of 3 m / s without honeycomb using a variety of shapes: hexagonal, square, and circular. Each honeycomb shaped to 8mm diameter. The results of the analysis on honeycomb testing with variations in shape obtained the value of turbulence intensity that occurs in the test section, namely for hexagonal shape variations the flow that occurs is better than circular shape, while in circular shape variations the value of turbulence intensity is better than square shape. The results of the Reynold's number calculation show that the flow that occurs is laminar with the following values, in the hexagonal shape variation the value is 787, circular shape 956.48, and square shape 1199.42. After calculating the turbulence intensity and Reynold's number, we can conclude that honeycomb with hexagonal shape variation is optimal than circular shape, and circular is optimal than square.

Para esto, se explora como ambos conceptos ingresan en la teoría económica, se entremezclan entre sí y, sin embargo, respaldan la toma de decisiones. A manera de ilustración, mediante un análisis crítico del discurso, se analiza cómo el gobierno ecuatoriano presentó la crisis sanitaria del COVID-19 como un escenario de incertidumbre, pero el tratamiento dado se limitó a una situación de riesgo, con alternativas de acción aparentemente determinadas.
Academic Ghost-Writing in India: Situating the Transformations in the University System
Authors: Dutta Sangita
Published: December 2023

Ghost-writing in academia has always existed, but it is no longer limited to individual or scattered cases that do not warrant the status of an endemic problem worthy of serious research in education and knowledge production. With the progress of technology and communication, academic ghostwriting has crossed local boundaries, and it is now a global industry worth billions of dollars known as the contract cheating industry. While the academic community must understand and prevent how this global industry operates, it is equally important to understand the larger structural forms of a neoliberal society that enable the rise and endless expansion of the phenomenon of 'academic ghostwriting.' Consequently, it is also crucial to begin a conversation on the possible implications of the growth of this industry on science and the processes of knowledge production. This paper, therefore, discusses the phenomenon of academic ghost-writing or contract cheating and how it operates in a global market by drawing observations from one transnational ghost-writing company. The paper's primary objective is to situate the phenomenon of academic ghost-writing within the larger framework of the transformation of higher education, student mobilities, and the internationalization of University education.

Published: December 2023

In Indonesia, rice is a staple food consumed daily. The high purchasing power of the public for good quality rice makes this a reason for producers to add dangerous bleaching agents such as chlorine to improve the physical quality of the rice they sell. The use of unclear bleaching agents on rice that do not meet the requirements for permitted additives in food and whose concentrations exceed the threshold limits is dangerous for human health. This research aims to determine the presence of chlorine in white rice sold at the Pagesangan market. The methods used are qualitative and quantitative. Three of the five rice samples tested at the Mataram STTL Laboratory tested positive for chlorine. Chlorine levels in rice samples, sample C, were 367.4 mg/L, sample D was 275.1 mg/L, and sample E was 93.4 mg/L.

Praktik Sosial BSI Dalam Program Pengembangan UMKM di Kota Banda Aceh (Studi Kasus UMKM Capli Sambal Ijo Aceh)
Authors: Malika Della , Bukhari  , Nusuary Firdaus Mirza , Barakah Fadlan
Published: December 2023

This study examines the social practices in the Micro, Small, and Medium Enterprises (MSME) development program conducted by Bank Syariah Indonesia (BSI), exploring the relationship between agents and the structures within it. The objective of this research is to analyze the forms of social practices occurring in the MSME development program provided by BSI to MSMEs in the city of Banda Aceh, specifically focusing on the MSME known as Capli Sambal Cabe Ijo. Within this research, social practices tend to be dominated by the role of agents controlling the S-D-L structure, with agent motivation reflected in discursive awareness. The theoretical foundation for this study is Anthony Giddens' structuration theory, which identifies agents with various forms of awareness, including unconscious motives, discursive awareness, and practical awareness. Giddens also delineates the definition of structure into three propositions: Significance, Domination, and Legitimacy. The relationship between agents and structure forms a recurrence across space and time as a social practice. The research methodology employed is qualitative, utilizing a case study approach. The findings indicate that significance without the support of domination and legitimacy can lead to emptiness or the ineffectiveness of that significance. In the context of BSI UMKM Center as the Expert Agent and UMKM as the Lay Agent, three S-D-L propositions automatically shape social practices. Discursive awareness from each agent continually occurs across space and time, ensuring the sustainability of recurrent social practices. To address the issues raised in this research, both UMKM and BSI are expected to maintain the recurrence of social practices to ensure the ongoing success of the program and the preservation of the structure. This is necessary for the continuous perpetuation of social practices.

Published: December 2023

El maíz es el principal cultivo de la canasta básica en México, así como uno de los productos de mayor importancia comercial y económica a nivel nacional. Dentro de los principales factores del manejo agronómico que determinan su nivel de productividad se encuentra la fertilización. Actualmente derivado de los conflictos bélicos entre Rusia y Ucrania, existe un desabasto y por ende una elevación del precio de los fertilizantes. Por lo anterior, en este trabajo se analizó el factor de fertilización en la cuenca del Papaloapan para analizar el efecto que ejerce la nutrición química en el cultivo de maíz en función de su productividad en t ha-1 de grano. Se simularon tres escenarios de fertilización con el uso del modelo SWAT y se mapearon los resultados de los factores analizando estadísticamente la diferencia de medias de los tratamientos por medio de una Anova la cual arrojó un valor de P= 2e-16 mostrando diferencia significativa en los efectos de los factores analizados sobre el rendimiento del cultivo. En conclusión, el factor de fertilización fue superior al de no fertilización con una diferencia entre medias de 7.8 t ha-1 de grano, lo cual indica que la ausencia de la labor de fertilización del cultivo impacta negativamente sobre la productividad de grano de maíz. Sin embargo, se encontró que la eficiencia entre media dosis y dosis completa de fertilización nitrogenada en términos de rendimiento es similar, siendo el factor de media dosis más eficiente que el anterior.

Published: December 2023

This research will discuss the 6 principles of Islamic communication which form the basis for the application of netizen communication ethics on social media TikTok with the background being the phenomenon of netizens who are still not wise in using good words in communication so that it can cause problems within the scope of social media. Because what someone says, that's what describes the actual behavior. That way, social media that exists today, including TikTok, should not become a vehicle for doing bad and useless things or actions, but must try to make TikTok a positive and useful tool, because everything that is done will definitely be accounted for. This research uses a method through a qualitative approach with data analysis studies using the analytical model of Miles and Huberman. The result of this study is an analysis of the attitude of netizens who have been able to apply the six principles of Islamic communication to become wise netizens, which is shown by using good words and not causing conflict. Because as Muslims, they must be able to interact with sincere intentions to establish friendship and improve the quality of positive relationships with other people, in order to create a harmonious situation and atmosphere among TikTok users and if successfully implemented continuously it will benefit not only in the world but also in the afterlife.

Penelitian ini akan membahas mengenai 6 prinsip komunikasi Islam yang menjadi landasan dalam penerapan etika komunikasi netizen di media sosial TikTok dengan dilatarbelakangi oleh fenomena netizen yang masih belum bijak menggunakan kata-kata yang baik dalam berkomunikasi sehingga dapat menimbulkan permasalahan dalam lingkup media sosial. Karena apa yang dikatakan seseorang, itulah yang menggambarkan perilaku yang sebenarnya. Dengan begitu, media sosial yang ada saat ini termasuk TikTok jangan sampai menjadi sarana dalam melakukan hal-hal atau tindakan yang buruk dan sia-sia, tetapi harus berusaha untuk menjadikan TikTok sebagai sarana positif dan bermanfaat, karena segala sesuatu yang dilakukan pasti akan dipertanggungjawabkan. Penelitian ini menggunakan sebuah metode melalui pendekatan kualitatif dengan studi analisis data menggunakan model analisis dari Miles dan Huberman. Hasil dari penelitian ini adalah analisis terhadap sikap netizen yang sudah mampu menerapkan keenam prinsip komunikasi Islam, untuk menjadi netizen yang bijak, yaitu ditunjukkan dengan penggunaan kata-katanya yang baik dan tidak menimbulkan konflik. Karena sebagai umat Islam, harus bisa berinteraksi dengan niat tulus untuk menjalin silaturahmi dan meningkatkan kualitas hubungan yang positif dengan orang lain, agar dapat menimbulkan situasi dan suasana yang harmonis sesama pengguna TikTok dan jika berhasil diterapkan secara terus menerus maka akan mendapat manfaat tidak hanya di dunia tetapi juga di akhirat

This paper deals on the implementation of the particle swarm optimization method for solving power flow problems in the Nigeria power system. The difficulty of solving optimal power flow (OPF) problems increases significantly with increasing network size and complexity. Some of the weakness of the conventional methods include: limited ability in solving real-world large scale optimization problems, weakness in handling constraints, poor convergence and slow computational time. The results gotten by implementing the Particle Swarm Optimization (PSO) algorithm in Nigeria 330kV 52-Bus network show that the total active power and reactive power losses were substantially reduced to 0.03MW and 0.05MVAR. The system time of convergence was faster at 0.5seconds. Also, the maximum line active and reactive power losses on line 1 to 2 were reduced greatly to 0.00MW and 0.01MVAR respectively. These show that the system was better optimized with the PSO algorithm than the conventional method.

Introduction: The endolift technique has become known for using a laser beam with a 1470 nm wavelength emitted through an optical fiber inserted into the subdermal tissue with the aim of reducing subcutaneous fat and/or toning the skin through neocollagenesis. In Brazil it became popular and commonly called endolaser or endolift laser, as in addition to 1470 nm it also uses a length of 980 nm with the same therapeutic goals. Few complications have been previously reported, most of which include mild and transient erythema, edema, ecchymosis, and nerve palsy. However, the incidence of most serious cases has increased in Brazilian territory. Objective: This study aimed to describe the authors' experience through several cases of complications resulting from endolift or endolaser technique application in Br0061’zil, and which brought to light to some important complications after the procedure. Also, it brings a brief review of the world literature on the subject. Materials and methods: It was carried out exploratory research presented in a narrative review, to highlight the action of the endolift (1470 nm) or endolaser (980 nm) technique used in the treatment of aesthetic dysfunctions. The review explored scientific articles published and available in the following databases: MEDLINE (Online Medical Literature Analysis and Recovery System), PubMed (National Library of Medicine), SCIELO (Scientific Electronic Library Online), LILACS (Latin American Literature and of the Caribbean in Health Sciences), and Google Schoolar. Furthermore, it was were added to this study a series of complications cases from the using endolift/endolaser technique which happened in Brazil in a multicentric manner and developed with the use of various commercially available devices. Results: It was found that the endolift laser technique has the potential to cause important injuries during and after its use when used without suitable criteria for antisepsis, dosimetry and skin temperature controlling. The most common complications described in this study are peripheral neuropathies, burns, local infection and steatonecrosis, the latter considered the main one. However, it was also identified general complications such as hematoma, edema, hyperchromia and optic fiber breaks. Conclusion: Despite the few reports in the world literature, serious secondary complications to the use of subdermal laser using fiber optics (1470 nm and/or 980 nm) are totally possible of happening and have become common in Brazil. Therefore, deserving full attention to the adoption of appropriate application techniques to minimize such complications, among them: greater dosimetric control, adoption of appropriate instruments to better control skin temperature, and greater rigor regarding biosafety measures (mainly antisepsis) when handling the required instrument to perform the technique.

The commitment to provide clean water and proper sanitation is one of the goals of the Sustainable Development Programs (SDGs). The government of each region needs to strive for clean water for the community. Efforts to fulfill clean water can be realized with the Water Supply System. Water Supply System sustainability indicators need to fulfill three aspects of quality, quantity, and continuity. The aim of this research is to assess the sustainability of the ‘Sugio’ Water Supply System in Lamongan Regency which serves three villages, namely Sugio, Lebakadi, and Sekarbagus. The aspect of water quality, seen from the results of the analysis of the quality of production water, shows that it meets the quality standards as raw water for drinking water. The aspect of water quantity is calculated to meet water needs for the next 20 years. The calculations results show that the daily average debit requirement is 17 L/s and the daily maximum debit is 19 L/s, while the existing debit is 15 L/s. The aspect of water continuity is calculated from the ability to distribute water during an emergency. The calculation results show that the distribution of clean water when there is no source of electrical energy can only be carried out in a maximum of 1 hour 13 minutes 48 seconds. The conclusion obtained is that the sustainability of the ‘Sugio’ Water Supply System from the aspect of water quantity and continuity still needs to be improved.

Set-back jumping plane out due to earthquake depends. The purpose of this study is to determine what percentage of set-back field jumps are safe in multi-storey building structures when given earthquake loads, evaluate the behavior of building structures when viewed based on displacement and drift ratio and evaluate the effect of the elevation height of the set-back field jumps on building safety.In this study, the building is modeled as high as 7 floors and 6 floors with elevation heights of 28 m and 24 m using the SAP 2000 program which is used to analyze earthquake forces with the variational response spectrum method. The modeling studied was 8 modeling, namely at a height of 7 floors (building structure with set-back out 50%, 30%, 20% and 10%) and at a height of 6 floors (building structure with set-back out 50%, 30%, 20% and 10%). Based on the results of the research that has been done, the percentage of safe set-back exit plane jumps in the 7-storey high-rise building structure is in the modeling with a 10% set-back exit because the displacement value is below the allowable limit. As for the 20% and 30% set-back modeling, the displacement value of the top floor exceeds the allowable limit value. However, if the number of floors in the set-back section is reduced by 1 floor (to 6 floors) the structure is safe for every percentage of modeling.

A ponte pedonal é uma estrutura mista que atravessa o Rio Dinha, com um vão de 35 m, a unir as margens ao longo do rio. A sua forma esbelta e arqueada combina com a paisagem natural local. Simultaneamente, a escolha arrojada da cor faz com que a estrutura se destaque dos tons verdes e castanhos da envolvente, convidando os peões a fazerem a travessia.
A ponte da Figueira da Foz. Projeto e construção do tabuleiro (2.ª parte)

Ainda antes de se iniciar a preparação da construção – fabrico, transporte e montagem – de qualquer estrutura metálica, de média ou de grande dimensão, é imprescindível avaliar todas as hipóteses viáveis para a movimentação e colocação nas suas posições definitivas das parcelas em que ela será decomposta, tendo em consideração, naturalmente, os condicionamentos que balizam essas hipóteses, quer os condicionamentos genéricos, comuns à maioria das estruturas, tais como os que limitam as dimensões e os pesos das peças a movimentar, quer os específicos da estrutura em causa. No caso do tabuleiro da ponte da Figueira da Foz, a limitação mais relevante a ter em consideração era, sem dúvida, a dificuldade em fazer chegar as parcelas do tabuleiro às suas posições definitivas, a cerca de 40 metros de altura e uma parte delas sobre o rio. Embora hoje em dia os projetos das grandes estruturas metálicas definam, no mínimo, as orientações gerais do processo construtivo, pretendendo-se com tal definição que ele esteja em conformidade com a conceção e o dimensionamento estrutural, na altura em que a ponte da Figueira da Foz foi construída nem sempre essa preocupação estava espelhada no projeto.
