Abstract

The activities of textile industry is often pollute the surrounding environment. It also occurs in industrial of Palembang  Weaving Songket. It influences the acidity and colored of the water. To manage this condition, the colored wastewater using adsorbents that absorbed from tea dregs. This study aimed to determine the effect of tea dregs adsorbent for wastewater quality improvement Songket industry. The Method of treatment of wastewater is used Batch system, which the wastewater is placed in a container by adding the adsorbent from the dregs of tea.  The used of variable is the absorption time for 2 hours, 4 hours, and 6 hours, with the composition of adsorbent mass 5 gr, 10 gr, and 15 gr. Tea dregs that used in this study has the 19.26% of hemicellulose, 39.54% of cellulose and lignin 20%. It takes four hours for the research in order to obtain maximum results, with tea dregs adsorbent composition that produces a pH smaller than the initial waste 6, COD content of 89.41 gr / L, and 3.993 ppm color intensity. Therefore, absorbent from the dregs of tea is very useful for the development of the textile industry, especially for Songket industrials.

Abstract

The Mocaf flour maker that made for this research consists of grater, dryer and discmill. In this research is caried out design of dryer that the type of belt conveyer dryer by using blower as a source of air suply and combining grater and discmill into one series. The performance test of the tool for this research is reviewed from the analysis of HCN and proteint content for the Mocaf flourproduced from Manihot Glaviozii for drying temperature in the dryer with temperature variations 80, 85, 90, 95 and 100 ℃. Based on the performance test of the tool, the drying process using temperature variations in the dryer affects the results of the reduction of HCN and protein content in the Mocaf flour products produced for drying process with the temperature variation showed that the greater the drying temperature, the greater the reduction of HCN and protein contained in Mocaf flour.The results of HCN analysis contained in Mocaf flour products experienced HCN reduction 66% while in the reduction of protein contained in Mocaf flour 67.83%

Abstract

The problem regarding the availability of raw materials for the timber industry encourages research on the use of lignocellulosic materials to develop, one of which is bagasse. The large amount of bagasse and plastic waste that is not utilized as waste in the community makes it possible to carry out further processing into particle board. Plastic waste that can be used as an adhesive in the manufacture of particle boards is high density polyethylene (HDPE) plastic. The method used was Hand lay-up, which was arranging the pattern of bagasse fibers randomly and bidirectional crossed, the ratio of adhesive and bagasse fibers 70:30, compressed by varying the pressing time of 15, 30, 45, 60, 75 minutes 150 0C and a pressure of 100 kgf/cm2. The best results from the manufacture of particle board under 60 minutes of pressing, the bidirectional arrangement pattern has better physical and mechanical properties than the random arrangement pattern. Showed the values of crossed bidirectional fiber moisture content is 4,898%, density 0.64 g/cm3, swelling 8.15% , water absorption 21.71% , MOR 483.11 kgf/cm2 and MOE 1740.95 kgf/cm2.

Abstract

The provision of breast milk (ASI) cannot optimally fulfill the increasing nutritional needs of infants after entering the age of 6 months, so it must be balanced with complementary feeding of breast milk (MP-ASI). One of the foods that contain lots of nutrients for babies is purple sweet potato. Purple sweet potato can be processed into a paste for raw materials for making biscuits as complementary food for ASI (MP-ASI). The aim of this research is to make biscuits according to SNI No. 01-7111.2-2005 using raw material for purple sweet potato paste. The concentration of bait used was 62.5%, 55.5% and 50%. Purple sweet potato paste is made using a rotary evaporator. The results showed that the optimum operating conditions for the rotary evaporator in producing the paste were at a feed concentration of 55.5%, the viscosity, density and water content values obtained were 311.4176 mPa.s, 1.0885 gr / mL and 57.7578%. The paste produced from the rotary evaporator is then used to make purple sweet potato biscuits. The analysis showed that the carbohydrate, protein, fat and water content were 39.30%, 8.42%, 20.35% and 16.05%. The purple sweet potato biscuits that were produced were close to SNI No. 01-7111.2-2005.

Abstract

Iron (Fe) is an essential metal whose presence in certain amounts is needed by living organisms, but in excess amounts it can cause toxic effects. This study aims to determine the effect of optimum contact time and optimum mass variation on Fe metal reduction using zeolite and manganese zeolite adsorbents. In addition, isotherm studies and adsorption kinetics were carried out. The variations in contact time used in this study were 0, 15, 30, 45, and 60 minutes. Meanwhile, the adsorbent mass variations used were 1 and 1.5 grams. From the results of this study it is known that the optimum time for the adsorption of Fe metal is 60 minutes with an adsorbent mass of 1.5 grams, a decrease in concentration of 51.1394% for manganese zeolite adsorbent and 47.6074% for zeolite adsorbent. . The iron ion adsorption process using zeolite and manganese zeolite follows the Freundlich adsorption equation model. The adsorption rates of zeolite on ferrous metals for masses of 1 gram and 1.5 grams tend to follow the second order pseudo kinetics model.

Abstract

The formulation of the problem in this study is how to design an absorber device (in terms of flow rate, packing height, and packing variation to ammonia concentration). This study aims to obtain 1 unit of ammonia absorber, reduce ammonia gas levels with an ammonia absorber and get the effect of H2O flow rate, packing height and packing variations on NH3 concentrations. The data analysis used was univariate analysis and bivariate analysis. The data collection technique used was purposive sampling. The research resulted in 1 unit of ammonia absorber with a tower diameter of 3.5 cm and a tower height of 60 cm. The results showed that the effect of H2O flow rate on ammonia concentration was very influential, it was found that the NH3 concentration value on packing height, namely: at the lowest height of 5 cm the amount of NH3 concentration was 5.9690 N and at a height of 60 cm the amount of NH3 concentration was 4.7518 N. The higher the packing height, the lower the NH3 concentration value, the NH3 concentration value obtained on the packing variation, namely: marbles packing of 4.198 N, stainless steel packing of 2.026 N and packi
