Abstract

The research aims to utilize polyethylene (PET), polypropylene (PP) and polystyrene (PS) plastic waste into liquid fuel by the pyrolysis process, currently, especially in Surabaya, a lot of waste, 13% - 14% is plastic. The results of the sample from this study are to distinguish the temperature of the steam entering the condenser and also the temperature of the water in the condenser. And what will later be tested is that the oil from the plastic is close to the type of gasoline or diesel. The results of this study found that the optimum temperature to get a lot of results in 1 kg of plastic type Polyethylene (PET) is with a steam temperature of 142°C and a time of 90 minutes, while the type of plastic Polypropylene (PP) with a vapor temperature of 180°C and plastic type Polystyrene (PS) with a vapor temperature of 100°C and a condenser temperature of 15°C. The amount of oil produced by Polyethylene (PET) plastic at that temperature is 40 ml. while the plastic type Polypropylene (PP) the amount of oil produced is 100 ml. and this type of polystyrene (PS) plastic can produce 20 ml of oil. This result means that it is worth 75% of the weight of the plastic that has been processed. Meanwhile, the yield of this oil is close to the premium type.. Keywords: plastic waste, pyrolysis, liquid fuel

Abstract

The demand for clean water by company employees who live in barracks is changing. This change in direction also affects the distribution of clean water, which will impact the effectiveness of the plumbing and pump systems. This analysis aims to know the plumbing installation and selection of the right pump so it can operate optimally. The method used is the analysis by ignoring losses, such as friction losses between the working fluid and the equipment. This analysis also calculates head, capacity, pump power, and efficiency. From the calculation result, we conclude that the flow capacity is 2,643 m3/min, and the total head installation is 71,69 m. So, a centrifugal pump with rotation 2951 rpm, type Groundfos CRN 90 4-2, is the best pump for installation. Keywords: pump, head installation, pump power, efficiency, capacity
