Abstract

Cockspur coral (Erythrina crista-galli L) petals are flowers that contain anthocyanins and active compounds of flavonoids and tannins. This study aims to determine the optimum conditions for the anthocyanin extraction process of cockspur coral petals using Microwave-Assisted Extraction (MAE), analyzed through the Response Surface Method (RSM). This process uses ethanol-hydrochloric acid solvents and a Box-Behnken experimental design involving three factors, namely the solvent ratios (w/v) (1:5, 1:15, and 1:25), microwave powers (300, 450, and 600 watts), and extraction times (3, 9, and 15 minutes). As a result, the second-order polynomial model was enhanced and sufficient to explain the variation of the data that denoted the significant correlation with the independent variables and the response. Derringer's desired function methodology was used for optimizing studies and generated ideal conditions for each or combined an independent variable.  The optimum anthocyanin extract of 5.82 mg/L was obtained at a power condition of 325,5 Watts, an extraction time of 3.05 minutes, and a solvent ratio of 20.5. Meanwhile, the operating conditions at a power of 310.8 Watts, a time of 14.94 minutes, and a solvent ratio of 24.96 resulted in the optimum color intensity (IC) of 1040.26. In the meantime, the optimum antioxidant activity was obtained at a power of 585.97 Watts, a time of 4.93 minutes, and a solvent ratio of 5.43 with IC50 of 0.115.

Abstract

The piping system is a fundamental process equipment in the industry. The phenomena that occur in piping systems vary depending on the conditions of the pipes and the fluids flowing through them. Therefore, research related to piping systems requires attention to minimize and understand the occurring phenomena. There have been many studies related to piping analysis, but what sets this research apart from previous studies is that it focuses on examining the contribution of each component of the piping system to friction loss-pressure drop. Furthermore, the data obtained is used to determine the deviation or difference between experimental data and theoretical calculations. This research aims to study the correlation between friction loss and pressure drop in piping systems (including pipes, elbows, and tees) and to determine the extent of deviation between theoretical calculations and actual conditions, as well as to understand the trend of such deviations. Results show that as the length of the pipe increases, there is an increase in pressure drop, especially for pipe lengths of 0.6, 0.8, and 1.4 meters, the values are 275.26, 367.0, and 642.27 Pa over density, respectively. Conversely, as the pipe diameter increases, the resulting pressure drop becomes smaller, namely for pipe diameters of 0.5, 0.75, and 1.25 inches, the values are 266.64, 93.33, and 13.33 Pa over density, respectively. In the observation of the influence of fittings, it is shown that the pressure drop generated by elbows is greater than that of tees, with values of 26.66 and 13.33 Pa over density, respectively. When calculating the percentage deviation, there is a tendency for longer pipes and larger diameters will increase the percentage of deviation. For pipe lengths of 0.4, 0.6, and 1.4 meters, the percentage deviations are 3.23, 10.11, and 17.50%, respectively. For variations in pipe diameter, the percentage deviations are 3.23, 41.74, and 47.15% for diameters of 0.5, 0.75, and 1.25 inches, respectively. Meanwhile, the percentage deviation for tees is greater than that of elbows, with values of 84.78% (for elbows) and 185.02% (for tees).

Abstract

Diversification of processed cassava into mocaf flour has the potential to be developed into products with high economic value. Mocaf flour made through a fermentation process has low HCN content and better organoleptic properties compared to cassava flour. Cassava roots are abundantly available and are the main commodities in Gunungpati, Semarang. On the other hand, the level of community welfare in this area is still low, hence efforts are needed to improve the economy through community empowerment activities. Efforts that can be made are to provide training and assistance in processing the local resources into products that have economic value. The training carried out was processing cassava into mocaf flour with participants from the PKK (Family Welfare Program) group in Ngijo, Gunungpati, Semarang. This training can improve the skills of the participants so that they can initiate the production of mocaf on a micro-enterprise scale. The series of activities that were done during this service program included the research steps and analysis of mocaf characteristics, followed by training in making mocaf flour for the community group and assisting in the initiation of MSMEs that produce mocaf flour.
