Abstract

Biogas pressure produced in a period of 10 days is 0.001 kg on the 3rd day to 0.013 kg on the 10th day or equivalent to an average of 0.0013 kg / day, which in each day experiences a different increase. The raw materials used are 8 kg cow dung and 2 kg pineapple skin waste with a raw material ratio of 4: 1 and 10 liters of water are added mixed with EM4. In this study, the authors compared the biogas pressure produced from a mixture of raw materials from cow manure and pineapple peel waste with biogas produced from a mixture of raw materials from cow dung and water hyacinth. The research method used is literature review, interviews and then the data collected will be used to calculate the ratio of biogas pressure. From the results of the biogas pressure comparison it was found that the mixture of raw materials for cow dung and water hyacinth was more effective than biogas with raw materials for cow dung and pineapple skin waste with a fermentation process within 10 days.

Abstract

In this modern era, the use of plastic is very much in the community, this alone makes the accumulation of plastic waste. And the nature of plastic waste has properties that are difficult to decompose and even need hundreds of years, this is also what makes the accumulation of plastic waste. Of the menabahnya amount of plastic such as plastic materials that can only be used and thrown for example are mineral water bottles, plastic bags or plastic food wrappers and This type of sterofoam waste is the most widely used and most piles of garbage collection.In my analysis process the plastic that will be processed using the pyrolysis method is rubbish whose category is plastic waste made from vinyl chloride, polyethylene, acrylic, silicone, urethane , which we can find most of its use as food packaging or household plastic appliances. Comparison of the first plastic garbage type of type 1: Polyethylene Terephthalate (PET or PETE or Polyester) and type 2: High Density Polyethylene (HDPE) , with the amount of plastic waste ratio of 1: 1. Comparison to two types of 1: Polyethylene Terephthalate (PET or PETE or Polyester) and type 4: Low Density Polyethylene (LDPE) , with a ratio of 1: 1 plastic waste. Comparison of all three types of 1 : Polyethylene Terephthalate (PET or PETE or Polyester) and type 6: Polystyrene (PS) , the amount of plastic waste ratio of 1: 1.Results from this study obtain data Data obtained from PET & HDPE experiments obtained oil and heat obtained from experiments 1 to 5. On The first experiment oil obtained was 0.15 Liters and Heat for evaporation of material was 2829.78 kJ. On The Second experiment oils obtained were 0.74 Liters and Heat for the evaporation of material 2829.78 kJ . On The third experiment oil obtained was 0.74 liters and heat for the evaporation of material 2829.78 kJ. On The Fourth experiment oils obtained were 0.74 Liters and Heat for the evaporation of material 2829.78 kJ . On The Fifth experiment oils obtained were 0.74 Liters and Heat for evaporation of the material 2829.78 Kj .Data obtained from PET & LDPE experiments obtained oil and heat obtained from experiments 1 to 5. On The First experiment oil obtained was 0.47 Liters and Heat for evaporation of 4119.3 kJ material . On The Second experiment oils obtained were 0.51 Liters and Heat for evaporation of 4334.22 kJ material . On The third experiment oil obtained was 0.36 liters and heat for evaporation of material 4226.76 kJ . On The Fourth experiment oils obtained were 0.44 Liters and Heat for evaporation of 5014.8 kJ material . On The Fifth experiment oils obtained were 0.5 Liters and Heat for the evaporation of ingredients 4477.5 Kj.
