Abstract

Dragon fruit skin, waste material (dragon fruit waste), will have a profitable sale value if it can be used as a food raw material. Dragon fruit skin waste contains relatively high dietary fiber so it can be used as a food raw material. This study aims to utilize dragon fruit skin waste for the manufacture of dragon fruit skin flour as an alternative food source. Some tests are made on white-meat dragon fruit skin, red-meat dragon fruit skin and super red dragon fruit skin. The preliminary study is the soaking of the three types of dragon fruit skin in two solutions, namely 0.1% sodium citrate and 0.1% sodium metabisulfite to prevent the browning effect on flour. Dragon fruit skin flour from the soaking with both solutions is then characterized physically, including its texture, color, flavor and rendement. The best physical characterization is followed by chemical characterization, including the contents of water, ash, protein, fat, carbohydrate, dietary fiber, minerals (Fe, Na, K, Ca and P), and also microbiological characterization of Escherichia coli, molds and Bacillus cereus. The chemical and microbiological characterization shows that the red-meat dragon fruit skin flour has better results than the white-meat and super red dragon fruit skin flour does. The red-meat dragon fruit skin flour contains 8.80% water, 0.20% ash, 2.35% fat, 7.69%, protein, 68,29% carbohydrate and 28,72% dietary fiber as well as 4.40 mg K, 8.76 mg Na , 0.65 mg Fe , 10.20 mg Ca and 32.58 mg P.

Abstract

Garbage is a classic problem causing environmental and ecosystem damage in every region, including in Bogor City. Plastic is one of the largest types of inorganic waste that causes ecosystem damage. In one day 1,7 tons of plastic waste are produced from a modern shopping center in Bogor. Several attempts were made to reduce the volume of inorganic waste. Since July 2018 the Regional Government of Bogor City has issued a regulation restricting the use of plastic bags in the modern market as an effort to reduce inorganic waste, especially plastic waste. Forecasting the volume of inorganic waste after the enactment of this regulation is needed as an evaluation step. The double exponential smoothing hole model is suitable for linear data trends. This is in accordance with the condition of inorganic waste volume data which tends to have a linear trend. Forecasting produces parameter parameter values α (level) 0,78 and γ (trend) 0,09 also MAPE 7,25%. The forecast results show that the volume of inorganic waste tends to increase in 2020. In order for this regulation to be optimal, it is necessary to consider applying these regulations not only in the modern market but also in the traditional market. In addition, it is also necessary to find an alternative to substitute for plastic so as not to switch to other inorganic types.
