Abstract

Penelitian ini mengusulkan sebuah prototipe reaktor microbial fuel cell (MFC) tanpa membran beraliran kontinyu. Dinding Reaktor dibuat dari pipa PVC dan elektroda dari serat karbon. Mikroba yang ditambatkan di anoda bersumber dari larutan FloTank. Pada penelitian ini digunakan limbah organik artifisial yang dibuat dari glukosa monohidrat dengan konsentrasi 250 mg/L COD. Waktu tinggal limbah divariasikan pada 0,5; 1; 1,5; dan 2 hari. Nilai rata-rata daya listrik yang dihasilkan untuk waktu tinggal limbah 0,5; 1; 1,5; dan 2 hari berturut-turut adalah 38,02; 43,01; 45,35; 46,71 mW/m2, dan daya volumetrik yang dihasilkan adalah 111,25; 125,86; 132,71; dan 136,69 mW/m3. Persentase penurunan Chemical Oxygen Demand (COD) limbah paling tinggi diperoleh pada waktu tinggal 1,5 hari yaitu sebesar 32,26%.

Abstract

Two frequently used methods in atmospheric dispersion modeling (ADMS and CFD) were compared in this study to predict pit retention within an open quarry. Conventional Gaussian plume models developed by CERC, ADMS 3 and ADMS 4, were used to predict the pit retention. This study mimicked Fluent CFD modeling of dust dispersion of a blasting event in Old Moor Quarry. A single blast event that liberated a typical 25,000 tons of rock released 1,900 kg of Total Suspended Particle (TSP). The emission source geometry was defined as a three dimensional block volume source of 70 m normal to the face, 80 m in width and 20 m in height. It was also assumed the TSP liberated over one hour had an emission rate of 4.71x10-3 g/m3/s. The four particle sizes were defined as 2.5, 10, 30 and 75 m at mass fractions of 0.05, 0.45, 0.3 and 0.2 respectively and the particles were assumed have uniform limestone density of 2600 kg/m3. The results indicated that ADMS and model based on CFD indicates similar trend, that is, pit retention is proportional to distance from source to pit edge along wind direction and proportional to inverse quarry gradient.Keywords: dust dispersion, blasting, ADMS, CFD, pit retention
