Prototipe Reaktor Hidrotermal Pengolahan Sampah Menjadi Bahan Bakar Padat

Abstrak

Trash is a waste material both from animals, humans and plants which is well used again and released into nature in the form of solids, liquids and gases. Based on data from the Environment and Hygiene Office of the City of Palembang, the amount of garbage in the last 6 years in Sukawinatan Final Disposal Site continues to increase every year, from 2013 to 2018 the amount of waste increased from 202,940,928kg to 264,858,892kg. To overcome this problem, a prototype of a hydrothermal reactor was designed which processes waste into solid fuel or briquettes. In this study the independent variables observed were temperature operation and stirring speed, Temperature and stirring speed variations are done to see the effect of temperature and stirring speed to heating value of solid fuel. the results showed that the higher the operating temperature and stirring speed, the higher the fuel heating value of temperature and stirrng speed. The highest calorific value produced at operating stirring speed of 350 rpm is equal to 7056.4546 kal/gr, with 7.90% ash content; vollatile matter 47.67%; water content of 22.97% and fixed carbon 21.46%.
