Abstract

Biogas is one solution to the use organic waste (livestock manure and vegetables). The aim of the research was to find out the effectiveness of livestock manure and fermentation of vegetable waste into biogas. This research was carried out using fermented vegetable waste for 10-12 days, then it was chopped and blended. The vegetable waste is then mixed with cow dung and water according to the determined variables. The mixture was put into a brown glass bottle and the bottle mouth was closed with a balloon and deposited for 8 days. Furthermore, the CO2 gas produced was released and start to deposite again for 20-30 days. Trapped methane gas obtained from in the balloon was then stored to measure the produced volume and pH and also the methane gas. The results obtained from the research that is were the best pH obtained from vegetable waste blender fermentation treatment (% water100 and the percentage of KS: SO was 75:25) was 7 and the largest volume was obtained from fermented chopped vegetable waste treatment (water% 300 and percentage KS: SO was 100: 0) of 78.73 cm3.

Abstract

Inventories of petroleum fuels are increasingly depleted and will someday run out. These shortcomings can be overcome by using alternative fuels, such as ethanol. Based on this, it is necessary to research and development of ethanol as a fuel. One way is with a separation in a packed distillation column. This study aims to assess the mass transfer phenomena that occur in the process of distilling a mixture of ethanol-water-amyl alcohol packed in column. In addition, this study aims to optimize temperature and reflux to obtain the highest levels of ethanol. This research method uses packed bed distillation system with the batch process. Feed used is synthetic ethanol, water, and solvent. Solvent used were amyl alcohol. Doing distillation with heating temperature is maintained. Distillation is done in the packing of stainless steel wool. Research carried out in a batch process with a variable temperature of  79°C; 84°C; 91°C; and porosity packing 20%; 30%; 40%; 50%; 60%; 70%; 80%.

Abstract

The biggest problem currently in Indonesia is the amount of garbage that accumulates and is not controlled anywhere, especially organic waste. There are also many methods to use waste. One of waste utilization is Biogas. Organic content contained in organic waste can be used as a substart source for anaerobic bacteria. Initial treatment of organic waste in this study used as a variable, namely chopped and blended. This initial treatment is done before it is mixed with other ingredients, ie cattle dung and water. 200% water is added to the reactor along with other variables. Temperature, pH and biogas volume were observed for 30 days. Initial treatment factor of organic waste as biogas production substand showed blend treatment with decay having higher biogas production than others, is 189.99 cm3 with a composition ratio of 50% cattle dung and 50% organic waste.

Abstract

Garbage is the biggest contributor to environmental damage, especially plastic waste that is not processed properly. One of the problems in the community is the management of plastic waste, which until now has not been controlled. It is estimated that each person consumes 170 plastic bags each year and that around 500 billion to one trillion plastic bags are used worldwide. As well as more than 17 billion plastic bags distributed free of charge by supermarkets around the world for each year. In fact, if all the plastic bags on earth were opened, they could cover the entire surface of the earth up to 11 times. Plastic is a material that is very familiar in human life and has been considered a staple for household or domestic needs so that the presence of plastic waste is increasing. The purpose of this research is to convert plastic waste bottles used for drinking water into fuel oil using the pyrolysis method. The reactor used is pyrolysis with a temperature of 200 °C, 250 °C, 300 °C, 350 °C, and 400 °C for 30, 60, and 90 minutes. After the fuel is obtained, it is taken for analysis of its heating value, flash point, ash content, moisture content, and composition analysis. The results of this research will help the processing of plastic waste in addition to used plastic bottles.
