Abstract

Lading Hotel is one of the hotel industries that has a strategic location in the city center of Banda Aceh. Lading Hotel produces domestic wastewater as much as 95,000 L / day generated from kitchen activities, laundry, bathrooms, and cafes. The wastewater preliminary results showed the parameter COD 381 mg / L and TSS 371 mg / L has exceeded the quality standards set by the government. To addresses these problems, this study aims to do a design planning of the wastewater treatment plant (WWTP) in Hotel Lading. The steps of treatment technology chosen in this study consist of equalization basins, sedimentation basins with additional aeration from blowers, anaerobic biofilter basins and subsurface flow type wetlands. The planning stages include collecting data, processing data, design planning, making BoQ and drawing conclusions. The results of dimensions calculation for design drawings e.i: the equalization basin is 3.6 m × 2 m × 3 m (7.4 m2), sedimentation basin with dimensions of 3.6 m × 1.8 m × 3 m (6.48 m2), anaerobic biofilter basin with dimensions of 2.4 m × 1.2 m × 3 m (2.88 m2) and Subsurface wetland dimensions of 4 m × 1 m × 1 m (4 m2). Total land area required for WWTP design planning was 20.76 m2.

Abstract

Tofu wastewater effluent contained high value of BOD, COD, and suspended solids which needed treatment before disposed to environment. The research aims to study the adsorption of BOD and COD in tofu wastewater using chemically impregnated carbon derived from coffee husks (Coffea Arabica L.). The Arabica coffee husk carbon (ACHC) activated with ZnCl2 0.1 N and CaCl2 0.1N for 3 hours. Carbon characterization compared with Indonesian standard of SNI No.06-3730-1995, and the surface area was examined by Fourier transform infrared spectroscopy (FTIR). The results showed that the moisture and ash content characteristics has met the Indonesian standard, but the iodine adsorption capacity was decreased with longer activation time. The highest iodine adsorption recorded at 888.37 mg/gr adsorbent using ZnCl2 0.1 N at 1 h activated time. The BOD and COD removal efficiency were 88% and 25%, for ACHC with ZnCl2 0.1N; Meanwhile carbon with CaCl2 0.1N has a removal efficiency 66% and 24% for BOD and COD, respectively. In conclusion, the variation of chemical activators and the longer contacted time gave significant effect on the removal of pH, BOD and COD from tofu wastewater. To obtain optimum COD adsorption efficiency in wastewater treatment, other factors such as the impregnation ratio, the activators concentration, the mixing time, and its combination method were needed further investigation.

Abstract

The development of lithium batteries is one type of research that continues to be developed. Recently, lithium batteries have become the most widely used source of electrical energy as raw materials for the manufacture of lithium batteries. This study aims to compare the synthesis with Co precipitation and sol-gel methods as electrodes in lithium batteries. Nanosized particles were characterized for characterization using (X-ray fluorescence (XRF) and scanning electron microscopy-energy dispersive X-ray (XRD) and (SEM) -EDS). Based on the XRF characterization test, the results showed that the chemical composition of Magnetite Fe3O4 contained in the iron sands of the Syiah Kuala beach showed material purities of 87.10%, 86.73%, and 81.42% (Magnetite Separation). This shows that the synthesis of Fe3O4 using the sol-gel method yields results with better material purity than the coprecipitation method. The results of the SEM-EDS characterization test observations were based on particle analysis and the distribution observed on the surface morphology of the particles, where the sol-gel method provided precise results for the synthesis of Fe3O4 magnetite nanoparticles. The results of the characterization test based on the EDS analysis based on the EDS test obtained the amount of Fe3O4 of 70.00%, this indicates that the composition of iron provides a high value compared to other components contained in it
