Abstract

Nowadays we were facing to the global warming which is causing climate changes. Global warming also promote by environmental degradation. Increment of human population and development on industrial realm are the main cause of environmental degradation. Wetland is one of environmental bufferwhich could enhance the environmental stress. Doing the wetland restoration is an effort to enhance ecological degradation. In this paper were discusses about wetland definition, functions, wetland restoration, effect of restoration and also some study cases of wetland restoration published by some researcher. Tidal Wetland Restoration itself could be defined as an actions taken in a converted or degraded natural wetland that result in the reestablishment of ecological processes, functions, and biotic/abiotic linkages and lead to a persistent, resilient system integrated within its landscape (Lewis, 1989). It must expect restoration could bring the better effluence to the ecology, however some time it’s not just happen like ideally. Some of the restoration activity could promote and lead the ecological degradation in the neighbor habitat from which restoration activity was conducted. Therefore to enhance the sustainability, restoration and good management should be applied in order and in good monitoring.  Keywords  :  wetland, ecological, restoration, sustainability.

Abstract

This paper was addressed to introducing new method of measuring the real wealth of environmental value either in the ecological point of view or economically. The new method proposed here was “Emergy analysis” (the available energy of one kind previously used up directly and indirectly to make a production or service). The Emergy analysis was used to gain overviews of the relationship between economy and ecology in relation to the decision making whether the environmental need conservations or not. In this paper some Emergy terminology was introduced as well as the definition of Emergy itself. Some of the Emergy terminology introduced here were; Energy, emergy, solar transformity, exergy, empower and EmValue. Procedure to do Emergy analysis was clearly discussed here and followed by Emergy indices calculation. Based on the result of Emergy indices calculations, we will get recommendation to make the suitable decision about a system, environmental or even production activity. Keywords : Emergy, transformity, Emergy-index, conservation.

Abstract

In this research, have perfomed the synthesis of chitosan from crab shell waste as a Chitosan/Zeolite (Ch-Z spherical) composite to reduce water hardness. The synthesis of chitosan can be done in three stages, namely demineralization, deproteination, depigmentation, and deacetylation. The stages of Chitosan/Zeolite Spherical (Ch-Z Spherical) synthesis were made with variations in the weight of chitosan: zeolite (w /w) 1: 0.5; 1: 1; 1:1.5 using Crosslinking Sodium tripolyphospat. The characterization results by using FT-IR for chitosan-zeolite weight variations at wavelengths of 4000-450 cm-1 show a typical IR spectrum for chitosan / zheolite Spherical (Ch-Z Spherical) successively at wavelengths of 1639 cm-1, 1638 , 71 cm-1, and 1638.58 cm-1 which is the -C⁼N strain or structural change (deformation) of NH2. The chitosan-zeolite spherical (Ch-Z spherical) composite was applied to reduce the metal Ca (II) and Mg (II) which can cause hardness in water. The effectiveness of 0.5 gram Ch-Z Spherical composites, we tested the variation of composite weights 0.1,  0.2, 0.4, 0.6, 0.8, and 1.2 gr as adsorbents of Ca (II) metal ) and Mg (II) with a concentration of 1000 ppm in 1 hour with the stirring process. The results obtained by a decrease of 99.69% at a weight of 0.6 grams and experienced constant along with an increase in the mass of adsorbent. While the effectiveness of the Spherical Ch-Z composite in reducing the concentration of Mg (II) by 99.4% in a weight variation of 1.2 gr. This shows the formation of active sites contained in the Spherical Ch-Z composite. Metal adsorption capacity of Ca (II) and Mg (II) obtained in this study amounted to 498 mg/g and 23.7 mg /g

Abstract

Aplikasi penggunaan ozon pada kegiatan budidaya sistem sirkulasi adalah solusi paling efektif dalam pengolahan air dan untuk menjaga kualitas air budidaya tersebut. Ozonisasi dapat menghasilkan proses brominasi dan juga mampu mengoksidasi konsentrasi amonia di dalam air laut untuk kemudian diuraikan menjadi senyawa yang lebih sederhana. Ozonasi juga menjadi solusi yang yang baik untuk menghilangkan amonia dari air laut. Lebih lanjut, amonia diduga mampu menjadi materi yang dapat menghambat (inhibisi) proses bromisasi ketika proses ozonasi air laut. Tujuan penelitian ini adalah untuk membuktikan proses yang terjadi pada saat ozonasi air laut. Hasil dari penelitian ini menunjukkan bahwa selama masih terdapat amonia terkonsentrasi didalam air laut, maka proses brominasi bisa ditekan hingga mendekati nol. Dengan adanya amonia didalam air, proses reaksi antara bromine dan amonia (NH3) dapat terjadi begitu cepatnya sehingga dapat mencegah senyawa bromine berubah menjadi bromat. Oleh karena itulah proses oksidasi amonia dapat menjadi senyawa yang dapat menghambat terbentuknya dan terakumulasinya bromat yang bersifat racun itu di dalam air laut. Amonia selalu terbentuk didalam kegiatan budidaya, baik dari hasil ekskresi sisa metabolisme maupun dari sisa pakan, maka hal ini dipastikan dapat menjadi agen yang menghambat proses brominasi dan memberikan kepercayaan bahwa aplikasi ozon pada budidaya air laut adalah aman untuk dilakukan. Namun demikian, dalam praktek budidaya sekala massal, konsentrasi ozon, ammonia, dan bromat harus di perhatikan dengan teliti untuk mendapatkan hasil produksi yang optimal pada budidaya system sirkulasi.  Kata Kunci: Ozon, ammonia, bromat, budidaya sistem sirkulasi
