Pengaruh Ukuran Dan Fraksi Organik Terhadap Kuantitas Dan Kualitas Timbulan Lindi

Timbunan sampah pada landfill (TPA) akan mengalami degradasi dan akan menghasilkan cairan (lindi) baik kuantitas maupun kualitasnya. Kuantitas dan kualitas timbulan lindi dari sampah perkotaan akan dipengaruhi oleh beberapa faktor seperti: komposisi dan karakteristik sampah, kadar air, umur sampah dan kondisi cuaca (iklim). Pada kegiatan studi ini bertujuan untuk mengetahui pengaruh komposisi sampah (jumlah fraksi organik) dan karakteristik sampah (ukuran butiran) terhadap karakteristik timbulan lindi.Dalam rangka untuk mendapatkan tujuan studi, maka metode yang diterapkan adalah melakukan percobaan laboratorium menggunakan reaktor biodegradasi volume 1500 mL. Dalam percobaan ini digunakan dua kelompok reaktor yaitu; kelompok pertama, digunakan untuk pengujian pengaruh persentase fraksi organik, sedangkan kelompok kedua dimaksudkan untuk pengujian pengaruh ukuran butiran sampah terhadap karakteristik lindi.Sebagai parameter kualitas lindi ditentukan TSS, BOD, dan COD, sedangkan parameter kuantitas lindi adalah volume cairan yang keluar dari reaktor. Berdasarkan hasil percobaan diketahui bahwa jumlah (persentase) fraksi organik dan ukuran butiran sampah dapat berpengaruh terhadap karakteristik timbulan lindi. Secara keseluruhan konsentrasi TSS, BOD, dan COD semakin besar sejalan dengan bertambahnya persentase fraksi organik. Hal yang sama terjadi untuk ukuran butiran samaph semakin kecil, maka TSS, BOD, dan COD semakin besar. Adapun volume timbulan lind

Analisis Resiko Lingkungan Pada Tempat Pembuangan Akhir (TPA) Sampah (Studi Kasus: TPA Piyungan Bantul)

Pembuangan sampah perkotaan pada Tempat Pembuangan Akhir (TPA) adalah cara yang paling banyak diterapkan di beberapa kota di Indonesia termasuk di Kota Yogyakarta. Timbulan sampah di wilayah perkotaan Yogyakarta sampai saat ini dilakukan di TPA Piyungan Kabupaten Bantul. Meskipun hal ini merupakan metode yang paling konvesional dan tidak sesuai dengan beberapa alternative yang lebih baik dalam rangkaian teknologi manajemen sampah perkotaan. Dengan adanya TPA maka akan diikuti dampak negatif terhadap lingkungan. Dampak negatif tersebut adalah dihasilkan timbulan gas dan lindi yang sangat berpotensi merusak lingkungan. Risiko lingkungan ini muncul jika Instalasi Pengolahan Air Limbah (IPAL) tidak mampu mengolah lindi sehingga melebihi standard baku mutu serta lapisan dasar TPA yang tidak memenuhi syarat sehingga lindi merembes kedalam tanah.Oleh karena itu dibutuhkan aplikasi sistematis dalam meminimasi kemungkinan terjadinya risiko terhadap lingkungan. Dalam studi ini dilakukan identifikasi dan analisis risiko lingkungan berdasarkan konsep manajemen risiko lingkungan dengan menggunakan metode kualitatif dan metode semi kuntitatif. Berdasarkan hasil identifikasi risiko dan analisis risiko terdapat empat komponen lingkungan yang mempunyai risiko tinggi yaitu pencemaran udara, pencemaran air tanah, berkurangnya estetika lingkungan dan pencemaran air permukaan yang disebabkan adanya timbulan gas, aliran lindi, rembesan lindi pada tanah serta bau

Grid Added Value to Address Malaria

Through this paper, we call for a distributed, internet-based collaboration to address one of the worst plagues of our present world, malaria. The spirit is a non-proprietary peer-production of information-embedding goods. And we propose to use the grid technology to enable such a world wide "open source" like collaboration. The first step towards this vision has been achieved during the summer on the EGEE grid infrastructure where 46 million ligands were docked for a total amount of 80 CPU years in 6 weeks in the quest for new drugs.Comment: 7 pages, 1 figure, 6th IEEE International Symposium on Cluster Computing and the Grid, Singapore, 16-19 may 2006, to appear in the proceeding

Conceptual design of a breed & burn molten salt reactor

A breed-and-burn molten salt reactor (BBMSR) concept is proposed to address the Generation IV fuel cycle sustainability objective in a once-through cycle with low enrichment and no reprocessing. The BBMSR uses separate fuel and coolant molten salts, with the fuel contained in assemblies of individual tubes that can be shuffled and reclad periodically to enable high burnup. In this dual-salt configuration, the BBMSR may overcome several limitations of previous breed-and-burn (B$\&$B) designs to achieve high uranium utilisation with a simple, passively safe design. A central challenge in design of the BBMSR fuel is balancing the neutronic requirement of large fuel volume fraction for B$\&$B mode with the thermal-hydraulic requirements for safe and economically competitive reactor operation. Natural convection of liquid fuel within the tubes aids heat transfer to the coolant, and a systematic approach is developed to efficiently model this complex effect. Computational fluid dynamics modelling is performed to characterise the unique physics of the system and produce a new heat transfer correlation, which is used alongside established correlations in a numerical model. A design framework is built around this numerical model to iteratively search for the limiting power density of a given fuel and channel geometry, applying several defined temperature and operational constraints. It is found that the trade-offs between power density, core pressure drop, and pumping power are lessened by directing the flow of coolant downwards through the channel. Fuel configurations that satisfy both neutronic and thermal-hydraulic objectives are identified for natural, 5$\%$ enriched, and 20$\%$ enriched uranium feed fuel. B$\&$B operation is achievable in the natural and 5$\%$ enriched versions, with power densities of 73 W/cm$^3$ and 86 W/cm$^3$, and theoretical uranium utilisations of 300 $\mathrm{MWd/kgU_{NAT}}$ and 25.5 $\mathrm{MWd/kgU_{NAT}}$, respectively. Using 20$\%$ enriched feed fuel relaxes neutronic constraints so a wider range of fuel configurations can be considered, but there is a strong inverse correlation between power density and uranium utilisation. The fuel design study demonstrates the flexibility of the BBMSR concept to operate along a spectrum of modes ranging from high fuel utilisation at moderate power density using natural uranium feed fuel, to high power density and moderate utilisation using 20$\%$ uranium enrichment.Cambridge International & Churchill Pochobradsky Scholarship, Ford Britain Trust Travel Grant of the Cambridge University Engineering Department, Copisarow Travel & Conference Grant of Churchill Colleg

Core design of breed and burn molten salt fast reactor

Previous designs of once-through solid-fuelled breed-and-burn (B&B) reactor and the conventional molten salt reactor (MSR) concepts suffer from material limitation of neutron irradiation damage and chemical corrosion. A novel breed-and-burn molten salt reactor (BBMSR) concept uses separate molten salt fuel and coolant in a linear assembly core configuration. Similar to Moltex Energy Stable Salt Reactor (SSR) design, the configuration with fuel salt contained in fuel tubes and coolant salt in pool type reactor vessel has been previously studied. The study confirmed that breed-and-burn operation is feasible in principle, however with a low neutronic margin. The objective of this paper was to seek improvements of the neutronic margin with a metallic natural uranium blanket design. A parametric study was performed for the natural uranium blanket design. BBMSR neutronic performance simulation was modelled using Serpent, a Monte Carlo reactor physics code, with a single 3D hexagonal channel containing a single fuel tube in an infinite lattice with reflective radial and vacuum axial boundary conditions. The addition of a metallic natural uranium blanket inside the fuel tube, which increases the natural uranium metal to fuel salt ratio (ϒ) of the BBMSR, was shown to significantly increase the neutronic performance of the BBMSR
