Abstract

Industrial WWTP sludge has not been used properly, especially biological process WWTP sludge can be used as an alternative fuel in the form of briquettes. The purpose of this study was to determine potential utilization of biological process WWTP sludge as briquettes, and to determine the effect of adding variations charcoal to the quality of briquettes. The biological process WWTP sludge was obtained from the Trio Food, Cianjur. The dried sludge has a calorific value 2468 cal/g. The research methodology includes material drying, size reduction (250 μm), mixing, molding, and briquette drying. Briquettes are made with variations in the addition of 30%, 40%, 50%, 60%, 70% charcoal. The results of the study showed that the addition of charcoal resulted increase in the water content, fixed carbon, and calorific value of briquettes as well decrease in ash content, and volatile matter. The highest calorific value in the variation of the addition charcoal is 70% at 3819 cal/g, the value still does not meet SNI 1/6235/2000 (standard for wood charcoal briquettes). The biological process WWTP sludge has potential to be used as fuel in the form of briquettes with the addition of coconut shell charcoal and carbonized coal.

Abstract

This research aims to find out the characteristics of Ficus carica L. drying process using a tray dryer and determine the effect of temperature and drying time on Ficus Carica L. flavonoid content using a tray dryer to obtain Ficus carica L. herbal leaf tea which is high in antioxidants. At the experimental stage, the water content of fresh leaves of Ficus carica L. were determined, so the water content is 74 ± 1.11% (wet base), then dried using a tray dryer at 35; 40; 45; 50; and 55oC, with a variation of the drying air flow rate of 1.3; 1.6; 1.9; 2.2; and 2.4 m/s. The optimum temperature and drying air flow rate are 50oC and 1.9 m/s since the highest flavonoid content was obtained at those condition as much 0.78 ± 0.001 gram QE/100gram extract. Dried products which packaged in tea bags have a content of 23.60% carbohydrate, total fat 3.50%, protein 5.35%,antioxidant 154.25 ppm and calorific value of 1430 Kcal/100 grams. It can be concluded that Ficus carica L. drying process using a tray dryer can be used to produce herbal leaf tea which is high in antioxidants and flavonoid content.
