Lembaga Keuangan syariah adalah suatu lembaga keuangan yang asas oprasionalnya berpacu pada dasar syariah. Ada beberapa macam produk akad dalam Lembaga Keuangan Syariah. Diantara banyaknya produk ialah produk pada akad yang dapat dimplementasikan yaitu kafalah. Yang diartikan dengan kafalah yakni suatu jaminan yang diserahkan oleh penanggung biasa disebut kafil terhadap pihak yang memberikan utang (makful lahu) demi melaksanakan tanggung jawab pihak yang berhutang. Pada LKS akad kafalah dapat diterapkan pada pengaplikasi Bank Garansi, dan  Letter Of Credit. Setiap produk akad pasti menerapkan praktik kafalah semuanya pasti ada fee. Akan tetapi masih banyak masyarakat yang bingung mengenai hukum keterkaitan fee kafalah dalam Lembaga Keuangan Syariah tersebut. Penelitan  menggunakan jenis penelitan library research atau literatur yakni cumber data bersumber dari buku, jurnal ataupun yang lainyan yang berkaitan dengan kafalah. Hasil penelitian mengenai hukum fee pada LKS perspektif fqih ialah terdapat sebuah perbedaan pendapat fuqoha ulama’. Pada dasarnya akad wakalah merupan suatu akad tabaru, bukan akad tijari yang dimana selalu mendapatkan fee. Dengan adanya perbedaan tersebut sebagian ulama’ fiqh tidak memperbolehkan. Selain itu juga sebaian ulama’ memperbolehkan adanya fee karena apabila tidak ada sebuah fee maka tidak akan membuat sebuah faedah atau sering disebut dengan kemaslahatan.

ABSTRAK
Artikel ini dilatarbelakangi oleh pangsa pasar yang besar mencerminkan minat masyarakat Indonesia sangat tinggi terhadap asuransi syariah. Sayangnya minat yang besar akan produk keuangan syariah ini terkadang kurang direspons oleh industrasi asuransi syariah. Padahal, dengan adanya asuransi syariah akan lebih memungkinkan untuk lebih cepat laju pertumbuhannya. Artikel ini menggunakan data kepustakaan atau library research dengan jenis yuridis-normatif. Dalam tulisan ini penulis meghasilkan asuransi syariah adalah suatu konsep di mana terjadi saling memikul resiko di antara sesama peserta. Sehingga, antara satu dengan yang lainnya menjadi penanggung atasa resiko yang muncul. Saling pikul resiko ini dilakukan atas dasar saling menolong dalam kebaikan dengan masing-masing mengeluarkan dana tabarru’ atau dana kebajikan (derma). Selanjutnya, asuransi syariah memiliki keunggulan dalam memenuhi rasa keadilan menjadikannya peluang untuk berkembang, adanya konsep bagi hasil dalam asuransi syariah di mana jumlah yang dibagi sesuai dengan proporsi hasil yang di dapat sehingga tidak ada yang dirugikan. Oleh karena itu, sudah banyak perusahaan asuransi konvensional yang mulai melirik produk dari asuransi syariah.
Kata Kunci: Perkembangan, Hukum, Asuransi Syariah.

Published: November 2024

Penelitian ini bertujuan untuk menganalisis kegiatan jual beli arisan uang dan tinjauan hukum islam dalam perspektif jual beli. Penelitian ini merupakan penelitian lapangan menggunakan purposive sampling  dengan teknik pengumpulan data pengamatan, wawancara, dan dokumentasi yang dilanjutkan dengan paparan data, analisis, dan pembahasan. Uji keabsahan  data menggunkan trianggulasi data. Lokasi penelitian ini di desa Grujugan RT 01 Kecamatan Cermee Kabupaten Bondowoso.
Arisan merupakan kegiatan mengumpulkan uang atau barang yang bernilai sama oleh beberapa orang kemudian diundi di antara mereka untuk menentukan siapa yang memperolehnya. Undian dilaksanakan dalam sebuah pertemuan secara rutin bulanan setelah kegiatan keagamaan pembacaan shalawat nariyah. Setiap anggota arisan pasti mendapatkan uang atau barang yang telah disepakati berdasarkan hasil undian tertinggi. Dalam arisan uang inilah terjadi transaksi jual beli arisan uang antar anggota yang merupakan ibu-ibu rumah tangga. Pada dasarnya al-Quran dan hadits sebagai pedoman muamalah umat islam membolehkan jual beli selama merujuk pada rukun dan syaratnya yang telah disyariatkan.
Hasil Analisis menunjukkan bahwa, pertama, praktik jual beli arisan ini yang diperjual belikan bukanlah barang melainkan kesempatan yaitu peristiwa atau waktu memperoleh undian tertinggi.  Kedua, transaksi jual beli ini tidak sesuai dengan rukun dan syarat jual beli dalam islam karena tidak adanya barang yang diperjual belikan.

KONSEP NEGARA HUKUM DAN KEABSAHAN NEGARA HUKUM
Authors: Usman Usman
Published: November 2024

Pembahasan Negara Hukum merupakan satu kesatuan antara Negara dengan Hukum, Yaitu apabila dalam suatu negara tidak terdapat satu atau dua aturan maupun hukum, maka kemungkinan besar negara tersebut tidak akan terkontrol. Hukum menjadi ujung tombak suatu keadilan, dengan ada hukum tidak ada kesembronoan orang dalam mengambil tindakan. Hal demikian sesuai denga pendapat Plato dalam bukunya “the Statesman” dan “the Law”, Plato menyatakan bahwa yang dapat diwujudkan adalah bentuk paling baik kedua (the second best) yang menempatkan supremasi hukum. Pemerintahan yang mampu mencegah kemerosotan kekuasaan seseorang adalah pemerintahan oleh hukum. Senada dengan Plato, tujuan negara menurut Aristoteles adalah untuk mencapai kehidupan yang paling baik (the bestlife possible) yang dapat dicapai dengan supremasi hukum. Hukum adalah wujud kebijaksanaan kolektif warga negara (collective wisdom), sehingga peran warga negara diperlukan dalam pembentukkannya.

Research Progress in the Construction of Delirium Risk Warning Model for ICU Patients Based on Decision Tree: A Review of the Literature
Authors: Yan Pengbo
Published: November 2024

Intensive Care Unit (ICU) delirium is a cerebral syndrome characterized by acute disturbance of consciousness, with an incidence of 38%-87%. The occurrence of delirium can lead to prolonged hospital stay, accidental extubation rate, mortality and other adverse consequences. Therefore, early identification of delirium and active correction of reversible causes appear to be particularly important. At present, the risk prediction models for delirium in ICU constructed at home and abroad mainly use logistic regression to build delirium risk prediction models for patients admitted to ICU≥24h. However, studies have found that as many as 25% of critically ill patients will develop delirium within 24h of admission to ICU. Therefore, it is particularly important to construct a delirium early warning model for patients entering ICU24h. Logistic regression model has low processing efficiency for non-linear and interactive data, and can not intuitively show the importance of each variable in the predicted result. As a non-parametric statistical method, decision tree can overcome the disadvantages of Logistic regression model and build a better prediction model. Therefore, this study used 24h after admission to ICU as the segmentation point to build a decision tree model for predicting early and late delirium in ICU patients, forming a corresponding risk level system, and compared it with similar delirium models to verify the predictive value of the decision tree model for early and late delirium in ICU patients, providing a basis for the formulation of further intervention and nursing plans. Thereby reducing the incidence of ICU delirium.

Authors: Bencheikh Salah Eddine , Bahmane Khadija , Djbrit Rim , Goudjil Mohamed Bilal , Segni Ladjel
Published: November 2024

This work is part of the study of the antibacterial and antioxidant activity of Algerian aromatic and medicinal plants. We conducted a study on a plant widely used by the local population, Citrus limon, an aromatic plant from the Ghardaïa region. Essential oils were extracted from Citrus limon (zest and leaves) using hydrodistillation, yielding 1.12% for the zest and 0.71% for the leaves. The essential oils were analyzed using GC/MS, identifying 35 constituents in the leaf oils, with 19.41% L-Limonene and 15.02% Nerol acetate, and 25 constituents in the zest oils, with 45.62% L-Limonene, 9.40 Beta-Pinene and 8.3% 3-Carene as major compounds. The antioxidant activity of the essential oils was evaluated using three methods. The first method was the DPPH free radical scavenging test, where the zest showed an IC50 of 135.678 mg/mL, higher than that of the leaf essential oil (IC50 of 34.238 mg/mL). The second method, potassium ferricyanide reduction (FRAP), showed that the essential oils of the leaves had an antioxidant activity of EC50 = 63.3773 mg/mL, and the zest showed EC50 = 200.875 mg/mL. The third method, ammonium phosphomolybdate, based on molybdate reduction (TAC), gave antioxidant activities for the leaves and zest, respectively, of EC50 = 1.5722 mg/mL and EC50 = 1.9604 mg/mL. The antibacterial activity was tested against six reference bacterial strains, with Klebsiella pneumoniae being the most sensitive to both essential oils, showing inhibition zones of 48 mm for the leaf oil and 40 mm for the zest oil. According to the obtained results, the essential oils appear to exhibit excellent antioxidant and antibacterial activity.
On a union of homogeneous sequences

Published: November 2024

A sequence of positive integers is said to be quasi-primitive if there do not exist three distinct integers such that the greatest common divisor of two elements is not the third. It is clear that the sequence of prime numbers is quasi-primitive. The Erdős quasi-primitive conjecture states that the sum of the reciprocal of the product of an element by its logarithm over any quasi-primitive sequence is maximized by the sum over the sequence of all powers of prime numbers. Note that Erdős, before introduce his conjecture, showed  that for any quasi-primitive sequence different from one, this sum is convergent and bounded by a real constant. In this article, by studying the analogous Erdős conjecture, we prove that when the real  is sufficiently large, there exists a quasi-primitive sequence such that the sum of the reciprocal of the product of an element  by the sum of its logarithm and , over this quasi-primitive sequence is very large than the sum over the sequence of all powers of prime numbers. Obviously, if the case where  equals zero is also true,  then the conjecture is false.

Published: November 2024

The 5G technologies are aimed to support a variety of vertically connected applications with heterogeneous devices and machines with significant improvements in terms of higher quality of service, increased network capacity and improved system throughput. However, 5G systems still face a number of challenges mentioned by researchers and organizations, and among these challenges, we highlight that millimeter wave links are very susceptible to blockage. If the line-of-sight communication path is blocked, reflexive path communication can help maintain communication. The shortest route was to take an alternate route when the first route was blocked. Among the proposed solutions to the blocking problem is an algorithm to distribute the power between different mmWave communication paths in order to overcome the masses of links under randomly distributed obstacles. The problem has been resolved with an exact method. In this article, we have optimized all the results of this exact method by applying a powerful metaheuristic technique called jellyfish search optimizer to maximize the overall capacity of the path between two nodes. The results showed that our approach procures an improvements exceed 100% over the results of the exact method.

Authors: Malika Ouzir
Published: November 2024

Sustainable waste management is becoming the focus of debates on environmental and economic issues, waste recovery has become a new logic, improving the quality of life of citizens and the environment and adding economic value to waste. In Algeria, landfill, which is simple or even "wild", was for a long time the final destination of this waste, because of its low cost compared to other sectors such as incineration or composting, without any other concern to recover this waste. Indeed , the recycling rate of municipal waste is only 7 % in Algeria (2012) and the targets for Algeria are respectively 20 % (2015) and 25 % (2020) according to the Euro-Mediterranean Regional and Local Assembly Report on Waste Management at Local and Regional Levels in the Mediterranean, Brussels, 2014. The technical landfill center of the city of Bourdj Bou Arreridj comes to eradicate the uncontrolled landfills in the city, but it has experienced several weaknesses and malfunctions in the way of exploitation.pain The objective of this study is to demonstrate by a qualitative/quantitative approach that an effective waste management in the town of Bourdj Bou Arreridj requires a selective collection and a good choice of the treatment of this household and similar waste which contains 75% fermentable/recoverable waste (organic matter) and more than 24% recyclable waste.

Authors: Hafsi Zoulikha , Oughilas Ahmed , Khane Yasmina , Zoukel Abdelhalim
Published: November 2024

This study investigates the synthesis and characterization of poly(ethylene succinate) (PES) thin films and their composites with copper oxide (CuO) nanoparticles. CuO nanoparticles were synthesized using a chemical  synthesis method, achieving an average size of 20 nm. PES/CuO composites were prepared by incorporating CuO at various concentrations of 0, 1, 3, and 5 wt%. The thin films were produced through solution polymerization followed by casting. Mechanical testing revealed that the tensile strength of pure PES was 25 MPa, while incorporating 1 wt% CuO increased the tensile strength to 30 MPa. At 3 wt%, the tensile strength reached 35 MPa, and at 5 wt%, it peaked at 40 MPa, demonstrating a significant enhancement in mechanical properties. The elongation at break also improved, increasing from 200% for pure PES to 250% for the 5 wt% CuO composite. Characterization of the materials was performed using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM) to analyze structural and morphological properties. The results confirm that the PES/CuO composites exhibit enhanced mechanical properties, indicating their potential for diverse applications in sustainable materials and biomedical fields.
OFDM system based on parametric DFT transform
Authors: Houda Atoui Nour el , Saad Bouguezel , Nourredine Amardjia
Published: November 2024

This study introduces a specific type of orthogonal frequency division multiplexing (OFDM) system that relies on the parametric discrete Fourier transform (DFT-alpha), where alpha is a parameter randomly selected within the range [-2pi, 0]. We investigate the performance of the proposed system across various channel types and modulation formats, including binary phase shift keying (BPSK), 16 quadratic amplitude modulation (QAM), analyzing aspects such as bit-error rate (BER), peak-to-average power ratio (PAPR), and computational complexity. This work considers the most interesting special case of the one-parameter DFT, which is the DFT-π/6 . The simulated results confirm the suggested OFDM system’s ability to minimize the computational complexity of the conventional OFDM system, standing as the primary contribution of the current study, while maintaining the performance identical. Therefore, the parametric DFT-OFDM system would be a good alternative to the classical DFT-OFDM. The findings suggest that parametric DFT based OFDM holds significant potential for high-speed optical wireless communication systems.

Hierarchization of sustainability indicators applied to inland waterway transport: a study in the Brazilian Amazon
Authors: Barbosa Kattylinne de Melo , Meira Leonardo Herszon
Published: November 2024

The Brazilian Amazon, a vital ecosystem for global sustainability, has significant potential for utilizing inland waterway transport (IWT) as a catalyst for socioeconomic advancement. However, the exploitation of waterways has frequently led to adverse impacts on riverside ecosystems, underscoring the urgent need to identify IWTs that balance navigation and cargo distribution requirements while safeguarding sustainable development objectives. For this reason, the utilization of sustainability indicators in IWT has emerged as pivotal for comprehensively assessing its environmental, social, and economic dimensions. To address this need, our study proposes a hierarchical framework of sustainability indicators tailored to cargo transport along the IWT of the Brazilian Amazon. Initially, 256 indicators were identified, 26 of which were selected for hierarchical analysis. Subsequently, a qualitative survey involving 30 specialists representing diverse backgrounds and expertise was conducted employing the analytic hierarchy process methodology. The findings highlighted the vital importance of environmental indicators. This result is aligned with the 2030 Agenda. Prioritizing investments following this hierarchy seems to have the power to catalyze socioeconomic development within the Brazilian Amazon (and possibly in other IWTs).

O cisto de baço, também conhecido como esplenoma cístico, é uma condição rara em que ocorre a formação de um pequeno saco cheio de líquido no baço. Geralmente assintomático, esse tipo de cisto é frequentemente descoberto incidentalmente durante exames de imagem realizados por outros motivos. No entanto, em casos mais graves, sintomas como dor abdominal, sensação de plenitude e desconforto podem surgir. O diagnóstico geralmente é feito por meio de ultrassonografia, tomografia computadorizada ou ressonância magnética. O tratamento pode variar dependendo do tamanho e dos sintomas associados ao cisto, podendo incluir observação cuidadosa, drenagem percutânea ou, em casos raros, remoção cirúrgica do baço afetado. O acompanhamento médico regular é essencial para monitorar o cisto e prevenir complicações, como ruptura ou infecção. Além disso, a diferenciação entre cistos primários, congênitos, e os secundários, resultantes de traumas ou infecções, é importante para guiar a abordagem terapêutica e determinar o prognóstico. O histórico do paciente e a avaliação clínica minuciosa são fundamentais para uma intervenção adequada.
A utilização dos resultados das avaliações de larga escala pelos diretores das escolas municipais de Teresina, Piauí
Authors: Santos Gilmar José dos , Moura Estegite Carvalho Leite
Published: November 2024

Este artigo investiga os fatores subjacentes à predisposição dos gestores escolares em utilizar os resultados das avaliações em grande escala. Essas avalições têm sido usadas pelos governos para desenvolver políticas educacionais e também como meio de accountability. Entretanto, os gestores escolares não estão convertendo esses resultados em ações concretas para buscar melhorias tanto nas dimensões pedagógicas quanto administrativas. Foi realizado um survey com 118 gestores escolares da rede municipal de educação pública de Teresina (PI), revelando três fatores associados a esse fenômeno: a predisposição à utilização dos resultados das avaliações, a percepção de problemas na divulgação dos resultados e a proatividade em relação aos resultados das avaliações. A pesquisa indicou também que não há correlação relevante e significativa entre esses fatores e o porte da escola, a idade dos gestores, a experiência destes na área educacional e o tempo no cargo de gestor. Os resultados corroboram as proposições teóricas sobre as avaliações em larga escala.
Experiência do usuário e requisitos não funcionais de software no ensino interdisciplinar de interação humano-computador e Engenharia de Software: uma revisão sistemática da literatura
Authors: Ferreira Josué Viana , Oliveira Sandro Ronaldo Bezerra , Portela Carlos dos Santos
Published: November 2024

Ensinar tópicos na área da computação envolve um conjunto de desafios, exigindo metodologias de ensino que precisam ser constantemente ajustadas para acompanhar os avanços e as mudanças tecnológicas. Nos cursos de computação, as disciplinas de Interação Humano-Computador (IHC) e Engenharia de Software (ES) abordam, respectivamente, as subáreas de Experiência do Usuário (UX) e Requisitos Não Funcionais de Software (RNFs). A UX visa garantir a satisfação do usuário ao interagir com um produto ou serviço, enquanto os RNFs tratam das características e limitações que o software deve atender, como desempenho, segurança e usabilidade. Dessa forma, a interdisciplinaridade dessas disciplinas é crucial na formação profissional dos estudantes de computação. No desenvolvimento de software, requisitos mal especificados podem levar a problemas significativos, como a entrega de funcionalidades inadequadas, atrasos no cronograma, aumento de custos, insatisfação do cliente e comprometimento da qualidade do produto. Como consequência, o software pode não agregar o valor esperado, resultando em uma experiência de uso insatisfatória e pouca ou nenhuma adesão por parte dos clientes. Diante disso, foi realizada uma Revisão Sistemática da Literatura (RSL) com o objetivo de analisar as metodologias de ensino aplicadas em tópicos relacionados a UX e RNFs. A revisão seguiu um protocolo que resultou na seleção de 30 estudos a partir de um total de 14.810 artigos publicados entre 2019 e 2024. Como resultado desta RSL, destaca-se a importância de integrar os conteúdos de UX e RNFs para proporcionar uma formação mais completa e alinhada às necessidades curriculares dos alunos, enfatizando a relevância de metodologias ativas que visam aumentar a participação, o engajamento, a motivação e o trabalho em equipe dos alunos no processo de ensino e aprendizagem.

Aquicultura refere-se à criação de organismos aquáticos e tem grande importância econômica no cenário mundial. Este trabalho analisa aspectos socioeconômicos da piscicultura semi-intensiva desenvolvida pela Associação Comunitária de São José do Caripí (ACSJC), na Reserva Marinha de Maracanã-PA. A pesquisa, realizada na comunidade local, envolveu visitações às propriedades rurais, utilizando metodologias do Diagnóstico Rural Participativo. O Município ainda dispõe de áreas cobertas de mata original de terra firme cujo solo é recoberto de floresta densa de baixos platôs. Devido a intensidade dos desmatamentos, hoje predominam florestas secundárias ou capoeiras em vários estágios de regeneração. A comunidade local é atualmente povoada por 40 famílias perfazendo 160 habitantes e a atividade econômica predominante é a agricultura de subsistência baseada no cultivo da lavoura da mandioca e macaxeira A vegetação de várzea A comunidade é composta por 40 famílias, majoritariamente dedicadas à agricultura de subsistência, com piscicultura focada no cultivo de tambaqui e seus híbridos. Entraves como escoamento da produção e falta de comprometimento de parte dos associados foram identificados. A ACSJC, com 12 membros, produz em média 2 toneladas/ha. A piscicultura, mesmo com recursos limitados, tem grande potencial de crescimento e demanda investimentos, políticas públicas e pesquisas para garantir o desenvolvimento rural sustentável e a melhoria da renda familiar dos associados.

Objective: The study aimed to analyze the influence of physical activity levels and the rs9939609 polymorphism (FTO gene) on anthropometric, hemodynamic, and cardiac autonomic variables in public school students. Methods: A total of 288 students (aged 11 to 18, both sexes) from public schools in São Luís, Maranhão, were divided into four groups: sedentary AA+AT (AA+AT sed), active AA+AT (AA+AT activ), sedentary TT (TT sed), and active TT (TT activ). Evaluations included the International Physical Activity Questionnaire, weight, height, body mass index (BMI), buccal cells collection for DNA extraction, systolic (SBP) and diastolic (DBP) blood pressure measurements, and heart rate variability (HRV) analysis. A chi-square test for allelic associations was applied a 5% significance level. Results: No significant differences were observed in DBP or heart rate (HR). The active groups (AA+AT activ and TT activ) exhibited reductions in weight and METs/min/week compared to their respective sedentary groups (P<0.05). The TT activ group also demonstrated reductions in SBP and BMI compared to the TT sed group (P<0.05). The TT activ group had higher HRV in the RR time domain (ms) compared to the TT sed group (P<0.05), though no significant differences were found in other HRV variables. Conclusions: The FTO gene polymorphism influences cardiac autonomic modulation, while physical activity levels affect anthropometric variables.
Uso do BIM na compatibilização de projetos
Authors: Gonçalves Maria Isadora Messias Bezerra
Published: November 2024

Com os avanços tecnológicos e arquiteturas cada vez mais robustas tornou-se imprescindível o uso de ferramentas que trouxessem mais confiança no processo de projetar e nas fases da obra, já que softwares mais comuns, como CAD, não eram mais suficientes pois serviam apenas como uma prancheta eletrônica e não agregavam informações reais ao modelo da construção. Diante disso, a tecnologia BIM se apresenta como um diferencial tanto no processo de realização do projeto, pois engloba ferramentas capazes de construir o modelo real de forma virtual, como na fase de construção, através de cronogramas e orçamentos mais completos e confiáveis. Porém, apesar dos inúmeros benefícios, a tecnologia ainda é pouco difundida em alguns países e muitos profissionais não utilizam tudo o que os softwares têm a oferecer. Dessa forma, esse trabalho busca fazer uma pesquisa qualitativa através da aplicação prática de uma das maiores vantagens do BIM, a visualização 3D para a compatibilização de projetos, e assim, poder analisar interferências de forma mais eficaz, levando para a obra projetos mais harmônicos e confiáveis, possibilitando a redução de custos e aumentando a produtividade no setor da construção civil.

Diversos simuladores são usados no treinamento de redes de computadores. No entanto, poucos se detém em transportar as habilidades manuais do usuário para o ambiente sintético criado. Este artigo apresenta uma investigação da aceitação de um simulador de ensino para montagem de redes informáticas com interação gestual, focando em aspectos como ergonomia, usabilidade e engajamento de estudantes voluntários. A partir da análise das percepções dos usuários, foi possível identificar que a estética, a facilidade de uso e a necessidade percebida influenciam significativamente a utilidade e a satisfação com o sistema. Além disso, os resultados destacam que a interação com o simulador, particularmente ao utilizar ambas as mãos, aumenta a imersão e a satisfação, embora limitações como a falta de integração de recursos sonoros e desafios para alunos com necessidades especiais tenham sido identificadas. O estudo sugere aprimoramentos futuros, incluindo a personalização da interface e o uso de reforços contínuos para melhorar a retenção de habilidades e a eficácia educacional do simulador.
