Abstract

Bioethanol is one of biomass based alternative energy. Biomass sources that can be used is lignocellulose from wood product waste. Consumption of paper and cardboard, which is one of wood product, of the world in 2015 reach 410,7 million tons. In this research, bioethanol is produced from raw material that is originated from wood product waste such as HVS paper, cardboard, and sawdust. Delignification is done to 50 grams of raw materials, than add 500 mL of H2SO4 10% for 2 hours and 100 °C. Hydrolysis with 5 grams of cellulase enzyme is done with 500 mL of water on pH 4 and 50 °C temperature for 4 hours. Fermentation in this bioethanol production use Saccharomyces cerevisiae with fermentation time variation of 8, 10, and 12 days. Furthermore, there are 2 stages distillation – adsorption process with adsorbent variation, zeolite 4A and silica gel for 60 minutes.

Abstract

The Mangetan Canal River is a river with a length of ± 36.3 kilometers which is often used as a place for waste to end up resulting in a decrease in the quality of the water (Ahmad et al, 2016). In this study, testing was carried out at 4 stations in the morning and evening for 4 weeks. The result is for parameters of temperature, pH, salinity meet the quality standards. For the DO parameter, COD has not met the quality standard. For brightness parameters only in weeks 1 and 2 that meet the quality standard. The composition of macrozoobenthos at week 1 to week 4 found 9 species belonging to 5 classes, namely Oligochaeta, Diptera, Gastropods, Celeoptera and Hirudinea. The density of macrozoobenthos showed the results of 15-1980 individuals/m2 per station during the study. For the calculation of IP and BMWP-ASPT, it was found that manganese was heavily polluted to very heavily polluted with the BMWP-ASPT method and the results were lightly polluted with the Pollution Index (IP) method. The results of the correlation between the Pollution Index and BMWP-ASPT are strongly correlated between variables (X) and (Y). The recommendation of this research is that sampling should be done in real time and it is necessary to develop other parameters that must be investigated that can affect the biota in the waters

Abstract

Bentor is a combination of rickshaw and motor, the smoke emitted by bentor has a high air pollutant content. One of them is Carbon Monoxide (CO). CO pollutants are dangerous compounds contained in exhaust smoke, if the smoke is scattered more and more in the air it will pollute the air and human health. CO pollutants can be minimized by adsorption. Adsorption is the process of absorbing a hazardous compound. This research utilizes kepok banana peel which is processed into activated carbon which will be used as an adsorbent to adsorb CO. Musa Acuminta Linn was carbonized and then activated using H2SO4 solution. This research modifies the bentor exhaust mixing addition of an adsorbent weighing 50 grams and is included in the exhaust. Behind the results of the research on the characteristics of activated carbon on the iodine absorber of 31%, it proves that the activated carbon from the kepok banana peel has met the requirements for activated carbon in accordance with the Indonesian Industrial Standard No. 0258.88 and this has an effect on decreasing the concentration of CO, which is able to reduce CO levels by 2% at idle conditions in the test time of 15 minutes.

Abstract

Chicken manure is an organic waste that can be a source of pollution for the environment if it is not treated before being discharged into the environment. The treatment offered to overcome this is the bioconversion process, namely the overhaul of organic waste by a fermentation process carried out by living things, one of which is Black Soldier Fly (BSF) larvae. The aim of the study was to determine the amount of reduction that BSF larvae can do in treating chicken manure with variations of bioactivators and modification of feed rates and their effect on the growth of BSF larvae and content in BSF larvae. The optimal reduction results in chicken manure without bioactivator was 66.7%, with MOL Rice 60%, MOL Pineapple 62.2%, MOL Papaya 62.2%, and EM4 66.7%. The average increase in body length of BSF larvae was 0.7 cm and the average weight gain was 0.4 g. The best content of BSF larvae to be given as feed for laying hens II according to SNI is BSF larvae by giving chicken manure waste without variation.
