Abstract

Coffee is one plantation crop that has long been cultivated and has a fairly high economic value. Data on world and domestic market demand for coffee commodities is increasing. World coffee production for arabica type is 60% and the remaining 40% is robusta type coffee. The key to the ground coffee production process is roasting. This process is the stage of forming the aroma and distinctive flavor of coffee from coffee beans with heat treatment. This study aims to determine the effect of the length of roasting carried out in the processing of coffee beans on changes in the acidity level of coffee powder. Data collection and analysis in this study used a non-factorial complete randomized design (CRD). The coffee roasting process uses a temperature of 1800 C with a roasting time of 20, 40, and 60 minutes with 3 repetitions. The results obtained showed that the acidity level of coffee powder decreased until it was close to neutral, namely P1 = 5.65%, P2 = 5.94%, and P3 = 6.27%.

Abstract

Duck eggs are a source of animal protein which generally have lower foam properties and stability compared to purebred chicken eggs, so that the use of duck eggs is still very less compared to purebred chicken eggs in various processed food products. One form of processed food product from duck eggs is salted duck eggs which are obtained by preserving them using salt (salting). In the preservation process, duck eggs are very susceptible to contamination, so alternatives are needed that can inhibit bacterial growth. Fragrant pandan leaves (Pandanus Ammaryllifolius) are believed to be able to suppress the growth of Escherichia Coli and Staphylococcus aureus bacteria, which are 2 types of bacteria that are an indication of food safety. The aim of this research is to determine the effectiveness of adding fragrant pandan leaf extract (Pandanus Amoryllifolius) on the quality of salted duck eggs produced. The method used in this research was a Completely Randomized Design (CRD) model analysis with the concentration factor of adding fragrant pandan leaf extract (Pandanus amaryllifolius). The method used in this research was a Completely Randomized Design (CRD) model analysis with the concentration factor of adding fragrant pandan leaf extract (Pandanus Amaryllifolius) consisting of 5 treatments, namely A = 0%, B = 3% C = 6%, D = 9 %, E = 12%. Each treatment was carried out 4 times to obtain 20 experimental units. Each treatment was carried out 4 times to obtain 20 experimental units. The results of the research showed that the addition of fragrant pandan leaf juice (Pandanus Amoryllifolius) had a significant effect on the organoleptic test of salted eggs, marked by a decrease in weight loss, ranging from 0,14-13,26 with an  average value of 3.09. The total microbacterial test ranged between 0.63x10-7 CFU/mL- 16.16 x 10-7 CFU/mL with an average value of 6.15 x 10-7 CFU/mL, and organoleptic test that the panelists still like.
