Abstract:
The super red dragon fruit peels waste that is under utilized by the people and prefers to be thrown away, has a lot of nutrient content over the fruit flesh, and the decline in people's interest in fermented cassava causes the loss of cassava farmers. Therefore, it is necessary to do research on the innovation of fermented cassava which also adds value to the nutritional content. This study aims to determine the effect of the addition of super red dragon fruit peels percentage and the addition of yeast percentage to antioxidant activity.

The objective of the research results of which are presented in this paper was to determine the effect of selected physicochemical properties of fuels on ecological parameters of a diesl engine. Physicochemical parameters of fuel have a decisive effect on correct functioning, operating parameters, and cleanliness of the exhaust gas emitted to the environment by any combustion engine. Results of physicochemical studies can be useful in developing fuels blends of specific properties, whereas results obtained in the course of tests carried out on an engine test bench allow to optimize parameters
