DIAGNÓSTICO DAS ÁREAS DE PRESERVAÇÃO PERMANENTE DE UM RIO TRANSFRONTEIRIÇO: O CASO DAS MARGENS DE UM SEGMENTO DO RIO QUARAÃ/CUAREÃM
Authors: BERVIG ALINE ANDRESSA , FOLETO ELIANE MARIA
Published: July 2019

Tendo como ponto de referência o rio, a existência das áreas de Preservação Permanente/montes ribereÃ±os (APP's) é fundamental para a preservação das suas margens e, consequentemente, do próprio recurso hídrico. A expansão do espaço urbano e/ou espaço agrícola acarreta a supressão das (APP's) provocando dano ambiental. Nesse sentido, este trabalho teve como objetivo analisar as condições das áreas de Preservação Permanentes (APP's) e dos montes ribereÃ±os, como se denominam as (APP's) no Uruguai, nas margens de um segmento do Rio transfronteiriço Quaraí/Cuareím, localizado na fronteira do Brasil com o Uruguai. A metodologia qualitativa, inicialmente, de revisão bibliográfica, realizou um comparativo entre a legislação florestal e de recursos hídricos brasileira e a legislação ambiental uruguaia. Foram utilizadas imagens de satélite para localização e análise do trecho estudado na bacia hidrográfica do Rio Quaraí/Cuareím, situado entre os afluentes Arroio Pintado Grande, a Leste, e o Arroio Tamandu a Oeste. Como resultado se verificou que existem APP's/montes ribereÃ±os preservados. Entre os usos irregulares das áreas de Preservação Permanente podem se destacar a extração de areia das margens do rio e o avanço das fronteiras agrícolas, acarretando a necessidade urgente de amenizar os problemas ambientais mencionados.

A IMPORTÂNCIA DO “ESTAR AQUI”: DIMENSÕES ESPACIAIS DA PROXIMIDADE GEOGRÁFICA NA PESQUISA CIENTÍFICA EM REDE
Authors: Oliveira Allison Bezerra
Published: July 2019

A revolução das tecnologias de informação, processamento e comunicação tem possibilitado instantaneidade comunicacional nunca antes vista: de informações, sons e ideias. Tal perspectiva tem sido apropriada por diversos segmentos da sociedade e com diversos objetivos, o de multiplicar a produção do conhecimento é um entre tantos. A produção do conhecimento científico em rede com pessoas em espaços geográficos distantes tem sido assim compreendida como forte mecanismo de superação das desigualdades. Em meio a essas questões, o presente trabalho tem como objetivo analisar a importância da proximidade geográfica na pesquisa científica em rede mediante os contornos tecnológicos comunicacionais. Para tal, empreendeu-se reflexão teórica sobre o tema, mapeou-se as relações de pesquisa em rede no estado de Pernambuco na área de Farmácia como recorte metodológico, construiu-se um mapa de fluxos dessas relações e aplicou-se questionários com os pesquisadores. Os resultados obtidos apontam para a importância do “estar aqui” como elemento mais eficaz que a comunicação instantânea na troca de informações na pesquisa científica.
Productividad vs. Management: ¿Qué es lo que importa en el proceso de exportación?
Authors: Argañaraz Facundo Nahuel
Published: July 2019

En este artículo se presenta un modelo teórico y empírico para estudiar la contribución de la productividad y de prácticas gerenciales/administrativas sobre el estado exportador. Por el lado teórico, se desarrolla un modelo de heterogeneidad múltiple, donde las firmas pueden diferir en sus niveles de dos tipos de productividad: en costo ( φ ) y en management ( ζ ), en un contexto de competencia monopolística. Con esto, en el caso autárquico, el modelo alcanza dos condiciones (Condición de Beneficio Cero y Condición de Libre Entrada) que determinan, en primer lugar, cuáles firmas ingresan y producen en el mercado. Posteriormente, al abrir la economía al resto del mundo, el modelo no solo muestra cuáles firmas sobreviven en el mercado doméstico, sino también cuáles exportan. En consecuencia, las firmas más productivas no necesariamente exportan, debido a que la decisión de exportar también depende de cuán efectivamente la firma lleva a cabo un conjunto de prácticas administrativas para adaptar sus productos a la demanda externa. Por el lado empírico, se intenta medir productividad y prácticas gerenciales a nivel firma, usando distintos métodos y especificaciones para identificar sus efectos en el estado exportador, recurriendo a las olas de las Enterprise Surveys del Banco Mundial de 2006, 2010 y 2017 para Argentina. Los principales resultados indican que tanto la productividad como las prácticas de management afectan positivamente la probabilidad de ser una exportadora, y sus efectos son muy similares en magnitud.

Forbidden Songs of the Pgaz K’Nyau. By Suwichan Phattanaphraiwan (“Chi”). Translated by Benjamin Fairfield.
Authors: Phattanaphraiwan Suwichan ("Chi") , Fairfield Benjamin
Published: July 2019

The “forbidden” songs of the Pkaz K’Nyau (Karen), part of a larger oral tradition (called tha), are on the decline due to lowland Thai modernization campaigns, internalized Baptist missionary attitudes, and the taboo nature of the music itself. Traditionally only heard at funerals and deeply intertwined with the spiritual world, these 7-syllable, 2-stanza poetic couplets housing vast repositories of oral tradition and knowledge have become increasingly feared, banned, and nearly forgotten among Karen populations in Thailand. With the disappearance of the music comes a loss of cosmology, ecological sustainability, and cultural knowledge and identity. Forbidden Songs is an autoethnographic work by Chi Suwichan Phattanaphraiwan, himself an artist and composer working to revive the music’s place in Karen society, that offers an inside glimpse into the many ways in which Karen tradition is regulated, barred, enforced, reworked, interpreted, and denounced. This informative account, rich in ethnographic data, speaks to the multivalent responses to internal and external factors driving modernization in an indigenous and stateless community in northern Thailand.

Published: July 2019

The industry needs the rotodynamic pumps operating with ultra-low specific speed and relatively low flow rate more often. Designing of such structures on acceptable efficiency level is extremely difficult and require nonstandard approach to design as for example: drilled impeller or patented by author multi-piped impeller. Such pump elements are very easy to manufacture and operate with relatively high efficiency, but cavitation behavior is unknown.

This paper focuses on experimental research in order to determine the cavitation characteristics of the drilled impellers and multi-piped impellers. The test rig was presented. Impeller models were made by means of SLS Rapid Prototyping methods. Additionally, CFD calculations were presented in order to determine static pressure distribution in the inlet sections of the investigated impellers.
Simulation model for resource-constrained construction project
Authors: Biruk Sławomir , Rzepecki Łukasz
Published: July 2019

Repetition of the same processes on different objects or units of a construction project and their concurrent execution makes it necessary to use the same limited resources at the same time. Managers prefer simple heuristic priority rules to scheduling construction activities, but there is not one the best for all projects. In addition that the experience from deterministic scheduling problems and priority-rule methods cannot always be directly transferred to stochastic environment.

The paper presents the pure reactive simulation model for planning construction projects in random conditions, taking into account the availability of renewable resources. Conducting simulation tests allows for various priority rules to determine the distribution of construction project duration and evaluate the robustness of the schedule.

The paper analyzes the effectiveness of the selected priority rules in a pipe line project. In the analyzed project, the Dynamic Minimum Slack rule ensures the lowest average duration of the project in random conditions and the highest quality robustness. The analysis of the simulation results can help the construction manager to choose the procedure ensuring the timely completion of the construction project in the stochastic environment.

To examine the methodology for determining the moisture diffusion behavior of lignocellulosic biomass in steady and unsteady states (two stages of a sorption isotherm), the diffusion coefficients in the steady and unsteady states (D
SS and D
US) were investigated over a range of relative humidity (RH) from 10 to 90% using a dynamic vapor sorption (DVS) apparatus and a specifically designed cell kit. Thin samples with a thickness of 50 μm were prepared from three lignocellulosic biomasses, i.e. poplar, Chinese fir and moso bamboo. Based on Fick’s first and second laws, D
SS and D
US were determined. An increase in D
SS or D
US was observed with increasing equilibrium moisture content (EMC) or transient status, regardless of the lignocellulosic biomass species. The moisture-dependent D
SS of poplar, Chinese fir and moso bamboo was similar to values previously reported. Chinese fir and moso bamboo exhibited the highest and the lowest D
SS values, respectively, when the same EMCs were achieved. The results of this study revealed that D
SS and D
US of lignocellulosic biomass (even with limited dimensions) could be determined during a sorption isotherm in a wide humidity range. Furthermore, the results are helpful for simulating moisture transport behaviors in the fields of drying, paper packaging and wooden building maintenance.
Radio Over Fiber-Based Wavelength Division Multiplexed/Time Division Multiplexed Passive Optical Network Architecture Employing Mutual Injection Locked Fabry-Perot Laser Diodes

Published: July 2019

We demonstrate a radio-over-fiber-based hybrid wavelength-division-multiplexed/time division multiplexed passive optical network (PON) to transmit 5 Gbps data rate to serve 32 subscribers. A broadband light source (BLS) is realized by mutual injection locking between two Fabry-Perot laser diodes at the transmission section to seed wavelength-division-multiplexed channels. Mutual injection locking technique is used to enhance the performance over single Fabry-Perot laser diode and 15  dB/Hz improvements in relative intensity noise(RIN) is realized in our proposed network system. All-optical up-conversion of a 10-GHz 1.25 Gbps on off keying radio frequency (RF) signal is achieved using one single-arm Mach-Zehnder modulator (MZM). Transmission performance over 25-km single mode fiber is investigated. Low bit error rate with enhanced eye-diagram is obtained in our proposed system. As a result, the radio over fiber (ROF)-based wavelength-division-multiplexed/time division multiplexed PON set up employing mutually injection locked Fabry-Perot laser diodes can be a better choice in high speed long-haul optical communication system.
Profile of Centralization Practices for Preparation of Non-Hazardous Drugs in Quebec Hospitals
Authors: Painchart Lucie , Palamini Marie , Odou Pascal , Bussières Jean-François
Published: July 2019

Background

The preparation of many drugs intended for parenteral administration is centralized in the pharmacy of healthcare institutions. However, no data are available describing the range of drugs with centralized preparation. The objective was to establish a profile of centralization practices for the preparation of non-hazardous drug doses in the pharmacy departments of Quebec healthcare institutions.

Methods

For this cross-sectional descriptive study, an e-mail survey was distributed in March 2017 to the directors of the pharmacy departments of Quebec healthcare institutions. Respondents were asked to estimate the percentage of parenteral drug doses that were prepared centrally in the pharmacy, the name of each drug prepared this way, the criteria used to select drugs for central preparation, and the barriers to centralizing preparation of drug doses. Only descriptive statistical analyses were performed.

Results

Of the 30 directors of pharmacy departments invited to participate, 27 (90 %) responded, representing a total of 40 Quebec healthcare facilities. Overall, 232 individual drugs were centrally prepared in one or more of these facilities, for an overall median of 22 drugs per facility (min: 1, max: 101).

Conclusions

This is the first survey in Quebec and indeed all of Canada to identify the many medications that are centrally prepared in hospital pharmacies. The survey showed that the selection of drugs for central preparation differed widely across facilities. It would be desirable for pharmacy departments in this province to collaborate on standardizing practices for central preparations.
Eulerian modelling of compressible three-fluid flows with surface tension
Authors: Zhang Chao , Menshov Igor
Published: July 2019

The paper addresses a numerical approach for calculating three-fluid hydrodynamics on Eulerian grids with taking into account surface tension and viscous effects. The medium considered consists of three different compressible fluids separated with interfaces. The fluids are assumed to be immiscible. The three-fluid flow is described by the reduced equilibrium model derived from the non-equilibrium three-phase model by performing an asymptotic analysis in the limit of zero relaxation time. To simulate surface tension effects, we extend the continuum surface force (CSF) model of two-fluid incompressible flow to the case of compressible three-fluid flow. A thermodynamically consistent surface energy of the compressible three-fluid flow is obtained by means of splitting the surface tension between distinct fluids into pairs of specific phase related surface tensions. Some aspects of the numerical method for solving the system of governing equations of the considered three-fluid model are discussed. Numerical results presented demonstrate the accuracy and robustness of the proposed model in simulating dynamics of interfaces and surface tension effects.

Published: July 2019

Magnesium (Mg)-rich primer is considered as a substitute for high polluted chromate treatment technology to provide cathodic protection for aluminum (Al) alloy. In this paper, Mg-rich primer with comprehensive properties was prepared by modifying epoxy resin using direct mixing. Specifically, the influence factors on the dispersion of Mg powder in epoxy, the modification of epoxy resin using organic silicones and the performance of Mg-modified epoxy composite coating were studied. The results show that Mg powder with small particle size has a better dispersion in epoxy; The mechanical property such as flexibility and impact resistance decreases with the addition of Mg powder, but which was improved when using modified epoxy as the resin matrix due to introduction of Si-O-Si flexible chain; In addition, the grafting efficiency between hydroxyl terminated polydimethylsiloxane and epoxy resin was improved because of the introduced silane coupling agent like KH550 contains amino group; The electrochemical test results indicate Mg-rich primer could provide effective electrochemical protection for Al alloy by raising the corrosion potential and reducing the corrosion current density to bare substrate,respectively.

The present work refers to describe the effects of Al2Cu variations on various properties of thick-walled functionally graded (FG) cylindrical shell. Al-25 wt.% Cu hypo-eutectic alloy ingot is melted and centrifugally casted to obtain high entropy FG composite. A series of microstructure examinations such as FESEM and EDX analysis were carried out to determine the distributions of constituent phases and elements. It is revealed that the maximum volume fraction of Al2Cu particle is reached near the inner surface with 35.7 Vol.% and then reduces gradually to 32.5 Vol.% at the outer surface of FG cylindrical shell. The effects of the variations Al2Cu along radial direction of FG tube are discussed through Vickers hardness, wear rate, coefficient of thermal expansion and compressive test measurements. The experimental results show that the wear and hardness are varied in graded manner which the highest wear resistance with wear rate of 9.1×10−5
g/mm
2 and hardness with 153HV are found towards Al2Cu enriched zone or inner periphery. Moreover, the studied FG cylindrical shell shows drop 2.5% in yield stress and 4.5% in elastic modulus from intermediate to inner layers due to Al2Cu particles clustering in metal matrix.

cGMP plays a role in sensory signaling and plasticity by regulating ion channels, phosphodiesterases, and kinases. Studies that primarily used genetic and biochemical tools suggest that cGMP is spatiotemporally regulated in multiple sensory modalities. FRET- and GFP-based cGMP sensors were developed to visualize cGMP in primary cell culture and Caenorhabditis elegans to corroborate these findings. While a FRET-based sensor has been used in an intact animal to visualize cGMP, the requirement of a multiple emission system limits its ability to be used on its own as well as with other fluorophores. Here, we demonstrate that a C. elegans codon-optimized version of the cpEGFP-based cGMP sensor FlincG3 can be used to visualize rapidly changing cGMP levels in living, behaving C. elegans. We coexpressed FlincG3 with the blue-light-activated guanylyl cyclases BeCyclOp and bPGC in body wall muscles, and found that the rate of change in FlincG3 fluorescence correlated with the rate of cGMP production by each cyclase. Furthermore, we show that FlincG3 responds to cultivation temperature, NaCl concentration changes, and sodium dodecyl sulfate in the sensory neurons AFD, ASEL/R, and PHB, respectively. Intriguingly, FlincG3 fluorescence in ASEL and ASER decreased in response to a NaCl concentration upstep and downstep, respectively, which is opposite in sign to the coexpressed calcium sensor jRGECO1a and previously published calcium recordings. These results illustrate that FlincG3 can be used to report rapidly changing cGMP levels in an intact animal, and that the reporter can potentially reveal unexpected spatiotemporal landscapes of cGMP in response to stimuli.

Authors: Dixon Gabrina , Kind Terry , Wright Joseph , Stewart Nikki , Sims Alexandra , Barber Aisha
Published: July 2019

OBJECTIVES:

Our objective for this study was to explore the experiences of faculty in academic pediatrics who are underrepresented minorities (URMs) at 2 urban medical centers, in particular, the experiences that influenced their pursuit of academic pediatrics.

METHODS:

Three focus groups were conducted in 2016 with URM faculty from Howard University College of Medicine and Children’s National Health System to explore how they were influenced to pursue academic pediatrics. Ten 1-on-1 interviews were also conducted in 2017 with URM faculty at Children’s National Health System. Focus groups were coded and analyzed by the research team using standard qualitative methods. The 1-on-1 interviews were coded and analyzed by the primary investigator and verified by members of the research team.

RESULTS:

A total of 25 faculty participated in the study (15 in the focus groups and 10 in individual interviews). Eighteen of the faculty were women and 7 were men. Findings revealed that mentorship, family, and community influenced participants’ career choices. Barriers for URMs in academic pediatrics included (1) lack of other URMs in leadership positions, (2) few URMs practicing academic pediatrics, and (3) the impact of racism and gender and implicit bias in the medical field.

CONCLUSIONS:

Mentorship and family are major influences on why URMs become academic pediatricians. Lack of URMs in leadership positions, racism, gender bias, and implicit bias are barriers for URMs in academic pediatrics. More research should be conducted on ways to enhance the experience of URMs and to reduce barriers in academia.

O tipo omnipredicativo de língua é definido pelo fenômeno de a maioria das entradas lexicais poderem funcionar por si só como predicados. O presente artigo investiga as características apresentadas por quatro línguas da família Tupi-Guarani (Tupinambá, Guajá, Apyãwa e Nheengatú) que, além da indistinção entre nomes e verbos que funcionam como predicado, apresentam outras características omnipredicativas. A manifestação diferenciada dessas características nas quatro línguas permite avaliar que há uma tendência à perda gradativa da omnipredicatividade quando se comparam as línguas mais conservadoras com as menos conservadoras e atesta que, sincronicamente, as línguas se encontram em diferentes fases de mudança de um padrão mais prototipicamente omnipredicativo para padrões menos prototipicamente omnipredicativos.

Este artículo presenta una herramienta diseñada para recoger datos fértiles, verificables y comparables sobre clases de palabra en diversas lenguas. Su diseño resulta de la reflexión sobre los problemas teóricos y metodológicos que subyacen a la identificación y recolección de datos sobre las clases de palabra. La herramienta consiste en una serie de actividades lúdicas que se basan en la presentación de estímulos a grupos de hablantes de una lengua. Su objetivo es guiar al investigador en la planeación y recolección de proferencias de enunciados en contextos discursivos que contengan elementos lingüísticos que refieran a entidades, propiedades y eventos contextualizados. Para probar su viabilidad se llevaron a cabo pruebas piloto con hablantes de la lengua yuhup. Con esta herramienta se espera aportar a la investigación futura sobre clases de palabra y contribuir a la construcción de una base de datos comparable que alimente el análisis de las lenguas y la teoría lingüística.
La voz pasiva en yagán

Published: July 2019

La lengua yagán, que fuera hablada en el extremo sur de la isla de Tierra del Fuego y en otras islas cercanas al Cabo de Hornos (aunque en la actualidad está casi extinta), presenta una forma prefijal «tūmū-», entendida como pasivizador, conformada a partir de un causativo «tū» y un reflexivo «m(a)-». Este trabajo analiza el funcionamiento del prefijo «tūmū-» a partir de fuentes documentales de diversa índole provenientes del período de vitalidad lingüística (entre mediados y fines del siglo xix), y descripciones realizadas por lingüistas con los últimos hablantes, hacia 1980. Los resultados llevan, en primer lugar, a una sistematización de las estrategias morfológicas para la pasivización en yagán; en segundo lugar, a establecer cómo se codifica este fenómeno a través del cotejo de las estructuras sintáctica y semántica en ejemplos textuales y, finalmente, a correlacionarlo con otros casos de pasivas no canónicas ya conocidos.

En este artículo presentamos resultados parciales de una investigación mayor, cuyo propósito es estudiar la diversidad lingüístico-cultural en la zona de influencia de la Universidad Nacional de Moreno (unm) en Argentina. El estudio de la población que asiste a la Universidad se ha realizado por medio de la etnografía como herramienta metodológica fundamental. A partir de los datos obtenidos en esta primera etapa, hemos iniciado el relevamiento de corpus orales y escritos producidos por sujetos que se hallan en situación de contacto de lenguas y producciones de sujetos monolingües, que ofician como grupo de control. En esta ocasión, exponemos resultados vinculados a la etapa de indagación etnográfica. Este trabajo nos ha permitido ampliar nuestro relevamiento en la zona de influencia de la unm y conocer más acerca de la coexistencia de comunidades de habla diversas, algunas de las cuales se hallan en contacto con otras lenguas o variedades del español.

La sedimentación o espesamiento es la separación de líquidos y solidos con la finalidad de aumentar la densidad de la pulpa de descarga final y para recuperar la mayor cantidad de agua del proceso de beneficio de minerales, principalmente en el de oro. La sedimentación clásica se realiza por fuerzas gravitacionales y se desarrolla en equipos llamados espesadores. La floculación acelera la sedimentación por medio de la acción de la unión selectiva de partículas suspendidas. El diseño del sedimentador para una mina activa de oro en Antioquia se basa en teoría de Kynch, el método propuesto por Richardson y Zaki, el modelo de Mishler y el método de Coe y Clevenger. El desarrollo de nuevas teorías abrió un nuevo campo de investigación, buscando un método mas rápido y preciso. El análisis de sedimentación se realizó bajo el proceso de Kynch para la sedimentación batch. Se estima que el área es de 99.83 m2por lo tanto, un diámetro de 11.27 m de longitud. Para el calculo de la altura del lecho de solidos en el sedimentador se obtiene una altura de 0.82 m.

KONSTRUKSI WAKAF SECARA FIKIH
Authors: Jaenudin Jaenudin
Published: July 2019

Abstract: Endowments (waqf) in Islamic law is an importent act, done by wakif as eternal good deeds, to promote economic equality of the people. It has been carried out from the beginning of Islam, being developed up to the present time. By reviewing library materials related to waqf, it was found that waqf law has its own characteristics. Commonly, endowments are binding and should not be traded, but in Hanafi schools of thought, waqf is seen as a ghair lazim contract. Because of its unique and important position, the waqf law needs to be studied thoro­ughly, and should be designated as special law.Abstraks: Perwakafan dalam hukum Islam merupakan salah satu bagian penting dalam mewujud­kan keadilan ekonomi serta amal kebajikan yang terus berlangsung bagi wakif. Wakaf telah dilaksanakan sejak masa Nabi saw dan terus berkembang pada masa sahabat dan generasi setelahnya. Dengan penulusuran bahan pustaka yang terkait permasalahan hukum wakaf, ditemukan bahwa hukum wakaf memiliki ciri tersendiri dari hukum keben­daan (fikih muamalat). Di satu sisi, wakaf bersifat mengikat tidak boleh diperjual­beli­kan, tetapi pada madzhab Hanafi wakaf dipandang sebagai akad ghair lazim. Kerana kedu­dukan­nya yang unik dan penting, hukum wakaf secara fikih dikaji secara menyeluruh, bahkan dalam wakaf juga dilegilasi menjadi hukum yang khusus.
ISLAM NUSANTARA’s Perspective on JUSTICE IN POLYGAMY
Authors: Saebani Beni Ahmad
Published: July 2019

Abstract: A man is allowed to marry more than one woman with one important require­ment, have an ability to act fairly. The sources of Islamic law, the Al-Quran and As-Sunnah, do not explain in detail the procedures or techniques of fairness for polygamous husbands. However, in the Law No 1 of 1974 concerning Marriage there are articles governing poligamy, as in Article 4 and Article 5. Those provisions show that in the  context of Islam Nusantara fiqh, polygamy is open to all men who want to marry more than one woman, but at once closed to a man who unable to the legislation require­ments. Through literature studies with jurudic-normative approach, this study found that Indonesia has its own approach to ensure that a polygamous husband can act fairly toward his wives. The article 4 and 5 of Law No. 1 of 1974 on Marriage proofing the intention. Therefore, the position of legislation as a result of Islamic Law transformation into national law becomes a concrete form of Islam Nusantara’s fiqh that has been applied in Muslim community life.Abstrak: Seorang suami boleh beristri lebih dari seorang dengan syarat memiliki kemampuan melaksanakan keadilan. Sumber hukum Islam, yakni Al-Quran dan As-Sunnah tidak menjelaskan secara rinci tata cara atau teknis melaksanakan keadilan untuk suami yang poligami. Akan tetapi di dalam Undang-undang Nomor 1 Tahun 1974 tentang Perkawinan terdapat pasal-pasal yang mengatur prinsip keadilan secara yuridis dan teknis, sebagaimana pada Pasal 4 dan Pasal 5. Dengan ketentuan peraturan per­undang-undangan tersebut dapat dipahami bahwa dalam konteks fiqh Islam Nusantara poligami terbuka untuk seluruh pria yang hendak menikahi lebih dari seorang isteri, akan tetapi sekaligus tertutup bagi pria yang bermaksud melakukan poligami apabila tidak terpenuhi persyaratan yang ditetapkan oleh peraturan perundangan-undangan yang ber­laku. Melalui studi literatur dengan pendekatan yurudis-normatif, penelitian ini mene­­­mu­­kan bahwa Indonesia memiliki pendekatan sendiri untuk memastikan bahwa suami yang poligami dapat bertindak adil terhadap istrinya. Pasal 4 dan 5 UU No. 1 tahun 1974 tentang Perkawinan membuktikan niat tersebut.  Oleh karena itu, posisi legislasi sebagai hasil transformasi Hukum Islam menjadi hukum nasional menjadi bentuk konk­ret fiqh Islam Nusantara yang telah diterapkan dalam kehidupan masyarakat Muslim.
