Abstract

Aneksasi wilayah Krimea oleh Rusia terjadi menyusul jatuhnya Presiden Ukraina Viktor Yanukovych yangdianggap pro Rusia oleh kelompok oposisi. Referendum yang dilakukan rakyat Krimea pasca aneksasi menegaskankembali tuntutan kemerdekaan Krimea dari Ukraina dan pilihan untuk bergabung dengan Rusia. Meski referendumtersebut dianggap tidak sah oleh Kiev, secara de facto Krimea kini berada di bawah penguasaan Kremlin. Tulisanini memfokuskan pada aksi aneksasi Rusia di Krimea dengan menganalisis kepentingan strategis Rusia di wilayahKrimea yang mendorong aksi aneksasi; termasuk menganalisis posisi Ukraina, Krimea, dan Rusia pasca runtuhnyaUni Soviet; serta konsekuensi lepasnya Krimea dari Ukraina yang merubah konstelasi politik domestik, sosial, danekonomi, serta batas wilayah Ukraina-Krimea-Rusia.Kata Kunci : aneksasi, Rusia, Krimea, Ukraina.

Abstract

Fundamentalisme adalah fenomena yang ada di setiap tradisi agama dunia seperti Kristen Yahudi IslamHindu dan Buddha Dalam beberapa dekade terakhir fundamentalisme memainkan peran penting dalam politikglobal khususnya dalam interaksi dengan demokrasi di beberapa negara Fundamentalisme muncul disebabkanoleh beberapa faktor tidak hanya terkait dengan persoalan agama namun juga kultural sosial politik dan ideologiSebagai sebuah ideologi tujuan fundamentalisme adalah untuk mengatur sistem politik sumber daya ekonomi dankekuatan sosial sebuah negara berdasarkan agama Penelitian ini mengkaji mengapa tren fundamentalisme meningkatdi negara negara seperti India Sri Lanka dan Turki yang menganut paham demokrasi Apakah ada korelasi antararealitas fundamentalisme dengan perkembangan demokrasi di negara negara tersebutKata kunch Politik global fundamentalisme demokrasi Hindu Buddha Islam India Sri Lanka Turki

Abstract

lobalisasi demokrasi menimbulkan persoalan baru dengan menguatnya identitas lokal di ranah publik. Ditengah kondisi tersebut, masyarakat cenderung untuk mengelompokkan diri dalam identitas-identitas asal, baikagama, suku, maupun wilayah.Fundamentalisme agama, baik dalam Islam, Kristen, Yahudi, Hindu dan Budha,menjadi salah satu varian dalam pencarian identitas tersebut.Pemikiran fundamentalisme menawarkan sebuah sistemyang menjanjikan bagi mereka yang mencari alternatif di tengah kegagalan tatanan sosial yang ada.Dalam kondisi semacam inilah muncul gerakan fundamentalisme agama, antara lain fundamentalisme KristenProtestan di Amerika Serikat dan Yahudi di Israel. Fundamentalisme Kristen Protestan menganggap Injil bersifatabsolut. Kelompok ini menolak gerakan modernisme yang menafsirkan kitab suci secara bebas dan elastis yangdisesuaikan dengan kemajuan sains dan teknologi. Begitu juga dengan fundamentalisme Yahudi, yang dalam perkembangannya gerakan ini menggunakan cara-cara kekerasan untuk mengusir bangsa Palestina dari tanah airnya.Kelompok inilah yang sampai di era politik Israel kontemporer memiliki visi fundamentalis ekstrem sehingga acapkalidisebut kaum ultra-ortodoks. Studi ini menganalisis fundamentalisme agama Kristen Protestan di AS dan Yahudidi Israel dan bagaimana kemunculan mereka di kedua negara tersebut yang menganut sistem demokrasi liberal.Kata kunci: demokrasi, fundamentalisme, Protestan, Yahudi, Amerika Serikat, Israel

Abstract

This study will examine the nature of silica and modified silica in the interaction with Cr (III) ion as an adsorbate. Properties that will be studied are kinetics and equilibrium of Cr (III) adsorption in solution. Studies begins with determining the existence of Cr (III) ion in solution at various pH values, the presence of adsorbent at various pH values, and the adsorption of Cr (III) ion in solution by the adsorbent at various pH values. Based on this data set also can determined some values, e.g the maximum adsorption capacity (notated as Qmax), and the equilibrium constant, the RL value that determined the nature of adsorption were favorable or not favorable. Similarly to the Freundlich isotherm. Adsorption kinetic and equilibrium were performed at pH 5. Each adsorbent has a different kinetic model. All of adsorbents has compatibility with Langmuir 2 isotherm model, and on these condition had favorable adsorption of Cr (III) ion. The highest Qmax value is at HSSN. In the Freundlich isotherm model can be stated that all of the adsorbent is favorable for the adsorption process of Cr (III) ion in solution..

Abstract

ABSTRACTPreparation of zeolite-clay concrete for new ethanol/water pervaporation without heating has been carried out. Concrete was made by mixing natural zeolite, portland cement, natural clay and distilled water in porcelain disk. The mixture was manually stirred until homogenous suspension obtained. The suspension formed was then placed in the mold and allowed to dry in open air for 48 hours. The mass of natural zeolite was varied from 10, 12.5, 15, 17.5, and 20 g meanwhile the mass of natural clay was varied from 0, 1.25, 2.5, 3.75, and 5 g. The mass of portland cement was fixed in the value of 10 g. The concrete was characterized by infrared spectrophotometer (IR) and X-ray diffraction (XRD). Material testing machine was used to determine the compressive strength of the concrete agreeable with decided ASTM C349-08 standard.Based on preparation of zeolite-clay concrete, it was found that the increase of the natural zeolite mass from 15 to 20 g caused fracture to the concrete, but water adsorption percentage increased from 27.7% to 35.2%. Meanwhile, the higher the mass of natural clay, the greater the compressive strength of concrete from 130.3 MPa to 179.9 MPa and water adsorption percentage from 28.9% to 32.3%. The adsorption-desorption data showed that the water was faster to adsorb into the concrete than ethanol, whereas the desorption rate of concrete with respect to ethanol was greater than that to water. The difference on desorption rate was then used to separate ethanol/water mixture through pervaporation without heating. Pervaporation test using the concretes resulted in the increase of ethanol feed concentration from 60%, 70%, 80%, and 90% to 82.9%, 82.5%, 87.8%, and 93.7% respectively.Keywords: concrete, compressive strength, adsorption-desorption, ethanol/water mixture, pervaporation.

Abstract

Telah dilakukan kajian analisis termal pada kitin-kitosan cangkang udang menggunakan thermogravimetric analysis dan differential thermal analysis (TGA-DTA). Kitosan dengan derajat deasetilasi (DD) bervariasi diperoleh dari proses deastilasi kitin dengan kondisi percobaan yang berbeda. Kitin dan kitosan dengan variasi DD tersebut dianalisis menggunakan TGA-DTA. Berdasarkan perbedaan termogram TGA-DTA kitin dan kitosan, menunjukkan bahwa kitosan lebih higroskopis daripada kitin dan memiliki gugus asetil yang lebih sedikit. Pada proses deasetilasi, kitin dimungkinkan terjadi degradasi rantai polimer dan pembentukan rantai polimer yang lebih panjang secara acak sehingga heterogenitas polimer kitosan lebih besar daripada kitin. Kata kunci: kitin-kitosan, analisis termal, termogram TGA/DTA

Abstract

The use of nanomaterial as a finishing agent in the textile industry continues to be developed. Nanoparticle zinc oxide (ZnONP) has anti-UV properties so that it can be used to protect the color of the fabric from fading. Constraints of using nanomaterial as a functionalization agent on fabric are the process of application and also its poor adhesion. This research aims to optimize ZnONP coating on cotton-indigo fabric so that ZnONP can be maximized adsorbed with good durability. Optimization is carried out by the Response Surface Methodology (RSM) method, with the independent variables are: ZnoNP Dispersion volume, the number of coating, and the method of coating (with and without sonication assisted). The response variable is the adsorbed ZnONP in fabric sample after the washing process. The number of coating and sonication-assisted coating gives significant results in increasing the number of adsorbed ZnONP.
