Abstract

Hospital solid medical waste contain hazardous and toxic materials. One way to manage solid medical waste is a mixed hospital as one of the ingredients in the manufacture of concrete blocks. The purpose of this study was to test the initial testing and the final content of cadmium (Cd) and chromium (Cr) heavy metals through the test the concentration of heavy metals, and to test the compressive strength of concrete blocks. In this research, the B3 waste treatment method using solidification technology by varying the 0%, 10%, 20%, 30% and drying time 14, 21 and 28 days and the test concentrations of heavy metals. The results showed that in terms of compressive strength 28 days, brick with a variation of 10% of age 14 days 105 kg/ cm2, 10% aged 21 days 135 kg/cm2 and 10% u it 28 days to 200 kg/cm2 where it is strong pressure to rise. From the test results are known concentrations of heavy metals mostly heavy metal content is 30% at 0.00034 ppm Cd of 0.180 ppm after disolidifikasi. Likewise, 30% of heavy metals in Cr is 8.509 ppm 0,044 ppm of immobilized so well that solid infectious medical waste can be used as a mixture of brick that is safe for the environment.Keywords: Infectious Medical Waste Solid, brick, Compressive Strength, Solidification, Heavy Metal Concentration Test.

Abstract

Waste is the residue of human activities that form of solid waste. Waste needs to be managed to avoid having a negative impact. One effort to manage a waste is to make the transportation of waste. The purpose of this research is to evaluate the transport of waste regarding the transport of waste in Zone III (Rumbai and West Rumbai District). Result of this research suggest that longer the distance a route takes, the greater the time it takes, it can be seen from the amount of time that TP 57 uses to drive longest. TP 57 have the longest route 62,95 Km. The exciting of waste transportation system in Zone III uses a direct pattern and manual SCS. The averaget total amount of time that is used to transport garbage per rotation is 5,110 hours/rotation, and the average of ritaion is 2 ritations per day. Calculating data indicate that waste hauling is ineffective and unproductive Productivity of waste hauling activities can be seen at off-route value. Average score off route That value falls below the range of productive waste hauling values. 0,09.Keywords: Waste Transportation, Waste transportation route, Waste transportation disances, Waste transportation time

Abstract

The process of palm oil mill wastewater treatment produced by-product as sludge. Sludge generated made a problem for environment and for industry when no handling and processing of the sludge. The purpose of this research is to reduce the pollution of palm oil mill wastewater by composting method with sludge, boiler ash and fiber (fiber) material of palm oil. Sludge mixed with boiler ash, fiber, and domestic wastethen added activator EM-4. Thisstudy used variety of activators EM-4  for 0,5%, 0,7%, 0,9% and control as comparator to optimize the composting process. The result showed that the compost with activator EM-4 for 0,7% likely matured faster because C/N ratio was suitable of SNI 19-7030-2004 and did not shows  significant differences. Compost matured in the 21th day  with result (C-org 27.22; Ratio of C/N  = 10.76;). Based on these results, palm oil sludge can be used as compost by using activators EM-4.  Keywords : activators EM-4, boiler ash, compost,  fiber, palm oil sludge

Abstract

The waste problem in Indonesia is a very complex issue. The example of waste that have huge amount of quantities is beverages cans. Waste cans can be reduced by utilizing from recycle the aluminum content to be the main material of potassium alum (KAI (SO4) 2.12H2O). In this study used carbonated drinks. The concentration of aluminium in soda cans is 84%, the concetration can be determined using Atomic Absorption Spectrophotometry (ASS). The variables used in this study is variation of KOH concentration whitin 20%, 30%, and 40% and the variation of H2SO4 concentration whitin 6M, 8M, and 10 M. From the results of this study showed optimum yield is 98.52% occurred at a concentration of 40% KOH and H2SO4 8M. Characteristic of this alum is having insoluble part in water of 0% and 5.39% aluminium in alum.Keywords : Cans, potassium alum

Abstract

The empty fruit bunch (EFB) is a solid waste from palm oil processing with the highest percentage of 23% per ton of the fresh fruit bunch (TBS), which has not been optimally utilized from the palm oil industry. EFB have 15-30% lignin components and complex chemical composition which is difficult to be degraded. To be easily converted into a simpler element, the bunches have to be firstly degraded. The utilization of the empty bunches as a medium to the growth of paddy straw mushroom (Volvariella volvaccea) is expected to degrade the content of lignin. The mushroom (Volvariella volvacea) produces extracellular enzymes in the form of LiP and MnP in degrading lignin. This study aims to study the effect of environmental conditions on the growth of straw mushrooms (Volvariella volvacea) on lignin degradation. This study has variation of seed mushroom weight of which 250 gr, 350 gr and control. The best results show that the highest percentage of lignin declining was found in the increasing weight of 250 gr paddy straw mushroom seeds which was 61%, with the achievement of optimum environmental conditions such as temperatures in the range 27.2-30.6 0C, pH 7.0-7.36 and water content of 42-85.2%. The conclusion of this study is that the optimum environmental conditions during the growth of the mushroom (Volvariella volvacea) become an important factor in the process of lignin degradation in the waste of EFB. Keywords : EFB, Lignin, pH, Temperature, Moisture content, Degradation

Abstract

One material that has potential to be used as raw material for bioethanol is the pineapple peel. Pineapple peel from the pineapple is one of the biggest agricultural waste in Indonesia, particulary in the area of Riau. Pineapple peel can be used as raw material for bioethanol production because contain much fibers, carbohydrates and glucose. This study aimed to obtain the highest amount of bioethanol from fermented juice pineapple peel using the yeast Saccharomyces cerevisiae by varying the concentration of tween 80 and comparing the nitrogen sources such as peptone and yeast extract and fermentation time is 24, 48 , 72, 96, and 120 hours. Measurement of bioethanol content using alcoholmeter. From the research results, obtained the highest bioethanol content of 9% v/v or 71,04 mg/ml in the additions at 20 ml tween 80 and a nitrogen source such as peptone and the fermentation time 96 hours.Keywords: Bioethanol, Pineapple Peel, Pepton, Saccharomyces cerevisiae, Tween 80, Yeast Extract

Abstract

The high dependence on fossil fuels and eco friendly fuel needs cause development of biofuels. Bioethanol is one of the biofuels that lately developed. In this research, theproduction of bioethanol from sorghum starch with the addition of Tween 80 and extract of Cordyceps sinensis mycelium variation as a supplement. The purpose of this study was todetermine the effect of variations in the addition of Tween 80 and extract of Cordyceps sinensis mycelium for the bioethanol yield and determine the effect of variations in thefermentation process time for the bioethanol yield. Sorghum starch was hydrolyzed to produce glucose using alpha amylase and glucoamylase enzyme. After hydrolysis wascomplete, the fermentation process was carried out in a 2L fermenter with variation time of 24, 48, 72, and 96 hours, variations addition of Tween 80: extract of Cordyceps sinensismycelium were 15 ml: 1.5 g; and 20 ml: 2.0 g. Bioethanol concentration was analyzed by gas chromatography. The addition of tween 80 and extract of Cordyceps sinensis mycelium effect on the activity of Saccharomyces cerevisiae in converting the sorghum starch into bioethanol, which can preserve viability of cell until the end of fermentation and produced higher ethanol yield. The production of bioethanol from sorghum starch results the best conditions on addition 20 ml of tween 80 and 2.0 grams of extract of Cordyceps sinensis mycelium in 96 hours fermentation time with concentration of bioethanol is 9,15024 mg/ml.Keywords: bioethanol, Cordyceps sinensis mycelium, hydrolysis, sorghum starch, tween 80
