Sintesis material BiFeO 3 doping Yttrium dibuat dengan metode sol-gel. Pertumbuhan kristal BiFeO 3 pada temperature 600°Cmemperlihatkan adanya fasa BiFeO 3 dan fasa kedua Bi 25 FeO 39 dan Bi 2 Fe 4 O 9 sebagai impuritas. Bertambahnya temperatursintering, impuritas fasa Bi 25 FeO 39 berkurang disertai hilangnya impuritas fasa Bi 2 Fe 4 O 9 . Morphologi material BiFeO 3memiliki ukuran butir 700.1 nm. Analisis elemen permukaan material BiFeO 3 dengan spektroskopi photoelectron sinar Xpada pengukuran energi binding 0 – 1400 eV memperlihatkan munculnya elemen permukaan Bi pada orbital 4f 7/2 dan 4f 5/2dengan energi binding 158 eV dan 164 eV, elemen permukaan Fe orbital 2p 3/2 dan 2p 1/2 dengan energi binding 710 eV dan724 eV, elemen permukaan O orbital 1s dengan energi binding 528 eV, dan elemen permukaan C orbital 1s sebagai elemenimpuritas yang memiliki energi binding 284,5 eV.Kata kunci : BiFeO 3 , Sol-gel, kristal, morphologi, photoelectron sinar X, sintering, impuritas, energi binding

Abstract

Penyesuaian kurva dengan program Delphi 6 pada Windows dilakukan untuk mencocokan hasil model dinamis Landau Khalatnikov dan kurva histeresis eksperimen dari lapisan tipis Barium Zirkonium Titanat (BZT) dengan doping Lantanum dan Indium yang di uji menggunakan rangkaian Sawyer-Tower. Serupa pada metode Rietveld pada difraksi sinar x, faktor R-Weighted Pattern (Rwp) digunakan sebagai pembanding antara hasil model dan eksperimen. Dengan memberikan variasi pada beberapa parameter seperti frekuensi, amplitudo medan listrik dan faktor skala mengakibatkan adanya perubahan pada hasil model. Hasil akhir menunjukan bahwa model cukup sesuai dengan hasil eksperimen.Keywords: Landau Khalatnikov, BZT, Sawyer-Tower circuit, Rwp

Abstract

This paper seeks to show that government policies that restrict intervention or no intervention at all in the unemployment rate become a-historical view and even irrational. The Postulat is in historical data that occurs at the time of al-Amin and al-Mamun and "initiation al-Shaybanı" -if not be called "theory of al-Shaybanı". In line with the context of the economic crisis at the time of al-Amin, the initiation of al-Shaybani which isimplemented by al-Mamun may be referred to unemployment"stabilization policy". The idea of al-Shaybani on social security establishedthe coherence with contractual policy which is substantively has six features: (1) share work and early retirement. (2) A policy in favor of the cost of labor turnover. (3) Profit sharing. (4) Low wages subsidy and a reduction in payroll taxes. (5) Subsidy of recruitment of new workers. (6) The transfer of profits. This contractual policy is voiced by Lindbeckand Snower (1988), M. Weitzman (1984).

Abstract

PZT (PbZr1-xTixO3 ) merupakan bahan berbentuk kristal perovskite yang dapat dimanfaatkan sebagai sensor inframerah. Penambahan sedikit dopan (bahan pendoping) dapat mengubah secara drastis karakteristik spesifik dari bahan keramik-ferroelektrik seperti polarisasi spontan, sifat dielektrik, sifat elektromekanik, elektrooptik dan sifat lainnya. Hard doping dengan menggunakan ion In3+ diaplikasikan pada penelitian ini dan dilakukan penumbuhan lapisan tipis dari bubuk PIZT (PbInxZryTi1-x-yO3-x/2) pada substrat Si(100) dengan metode Chemical Solution Deposition (CSD) dengan konsentrasi 0,5 M dan kecepatan putar spin coating 3000 rpm. Karakteristik bahan PIZT baik bubuk maupun lapisan tipisnya diuji dengan difraksi sinar x. Analisis Rietveld dilakukan dengan menggunakan program GSAS-EXPGUI dan diperoleh parameter kisi dan komposisi fasa dari kristal. Polarisasi spontan (Ps ) PIZT bubuk dan lapisan tipisnya mengalami penurunan dibandingkan dengan bahan asalnya (PZT). Polarisasi spontan yang optimum dari lapisan tipis PIZT dicapai pada rentang doping 0,5% - 1% In2O3. Momen quadrupol potensial listrik (FQ(r) ) bahan PIZT pada suatu titik P (0,0,2a) mencapai kondisi optimum pada % doping 6% In2O3 dan dari hasil penelitian ini juga menunjukkan bentuk lapisan tipis PIZT memiliki nilai (FQ(r)) yang lebih baik daripada bentuk bubuknya untuk rentang doping > 1% In2O3.

Abstract

Selection of optimal coconut varieties for coconut milk production is a crucial step in the food industry, considering that the quality and quantity of coconut milk are greatly influenced by the type of coconut used. This study aims to determine the best coconut varieties for coconut milk production by integrating two multicriteria decision-making methods, namely the Analytic Hierarchy Process (AHP) and Simple Additive Weighting (SAW). The AHP method is used to determine the weight of each influential criterion, such as oil content, taste, price, and availability. Meanwhile, the SAW method is applied to rank various coconut varieties based on the weight of the criteria that have been obtained. The data used in this study were collected from various sources, including scientific literature, as well as field observation data. The results of the analysis indicate that certain coconut varieties have significant advantages in terms of quality and efficiency of coconut milk production. The coconut varieties selected through the combined AHP and SAW methods are expected to provide practical guidance for coconut milk producers in selecting optimal coconut varieties, so that they can improve the quality of the coconut milk produced. Thus, this study provides an important contribution in the field of agribusiness, especially in the selection of coconut varieties for coconut milk production, as well as implementing the use of AHP and SAW methods in complex and multi-criteria decision making.

Abstract

This study develops a conceptual framework for integrating digital services within Islamic Social Finance (ISF), emphasizing a service-oriented approach to address limited strategic guidance for ISF institutions. It investigates how digitalization can enhance service design and implementation by examining ISF's unique characteristics and applying Service-Dominant Logic (SDL). Based on a literature review and qualitative analysis, the research highlights digitalization's potential to expand ISF services, improve stakeholder engagement, and optimize value creation. The proposed framework structures service systems around al-Maqāṣid (primary objectives), tailored to stakeholder needs. It advocates a shift from product-centric to beneficiary-centered service models, fostering engagement and collaboration among stakeholders. This approach aligns with Islamic principles while facilitating sustainable and effective service ecosystems. The study concludes that adopting a beneficiary-centered, digitally-enabled perspective significantly improves ISF service quality and accessibility. This framework provides a foundation for ISF institutions to transition towards more dynamic, innovative, and collaborative service models.======================================================================================================== ABSTRAK - Integrasi Layanan Digital dalam Keuangan Sosial Syariah: Kerangka Kerja berbasis Service-Dominant Logic. Penelitian ini mengembangkan kerangka konseptual dengan mengeksplorasi integrasi layanan digital dalam Keuangan Sosial Syariah (KSS) yang menekankan pada pendekatan berorientasi layanan guna mengatasi keterbatasan panduan strategis bagi institusi KSS. Makalah ini mengkaji bagaimana digitalisasi dapat meningkatkan desain dan implementasi layanan dengan penelaahan karakteristik unik dari KSS dan penerapan Service-Dominant Logic (SDL). Dengan mendasari pada tinjauan literatur dan analisis kualitatif, penelitian ini menyoroti potensi digitalisasi untuk memperluas layanan KSS, meningkatkan keterlibatan pemangku kepentingan, dan mengoptimalkan penciptaan nilai. Kerangka kerja yang diusulkan menunjukkan bagaimana sistem layanan dapat disusun berdasarkan al-Maqasid (tujuan utama), yang disesuaikan dengan kebutuhan pemangku kepentingan. Kerangka ini mendorong pergeseran dari model produk-sentris ke layanan yang berpusat pada penerima manfaat, membina keterlibatan dan kolaborasi antar pemangku kepentingan. Pendekatan ini selaras dengan prinsip-prinsip Islam sekaligus memfasilitasi ekosistem layanan yang berkelanjutan dan efektif. Studi menyimpulkan bahwa adopsi perspektif yang berpusat pada penerima manfaat dan didukung secara digital secara signifikan meningkatkan kualitas dan aksesibilitas layanan KSS. Kerangka kerja ini memberikan landasan bagi institusi KSI untuk bertransisi menuju model layanan yang lebih dinamis, inovatif, dan kolaboratif.
