Abstract

Pineapples are often consumed by humans and produce waste from pineapple skin, but the content of pineapple skin has a water content of 81.72%, crude fiber 17.53%, carbohydrates 4.41%, protein and reducing sugar both have the same content of 13.65%. Usually Mexican people make pineapple skin as a fermented probiotic drink or also called tepache. With the fermentation process in this probiotic drink, of course there is the effectiveness of the Lactobacillus casei microbe which has the ability to inhibit pathogenic bacteria that have the potential in making tepache which is utilized from pineapple skin against sugar concentration. Using the Experimental research method is a systematic, careful, and logical study to control a condition. From making pineapple tepache will produce different tastes, colors, textures and aromas. The less sugar concentration, the more sour it tastes and vice versa. the more sugar concentration, the sweeter it tastes. This is because there is a percentage of lactic acid which will lower the low pH value at the sugar concentration in it.

Abstract

This research examines quantitative approaches in flower dissection, with a focus on measuring symmetry and flower structure using mathematical formulas. This research aims to develop an objective method for analyzing flower morphology to support taxonomic, evolutionary and ecological studies of plants. Data was collected through morphometric measurements on various flower species with radial and bilateral symmetry characters. Parameters measured include petal length, corolla width, spreading angle, and number of reproductive parts. The analysis was carried out using geometric formulas to calculate the symmetry index and proportions of the flower structure. The research results show that flowers with radial symmetry have a higher symmetry index value than flowers with bilateral symmetry. Additionally, variations in flower structure were found to correlate with ecological adaptations, such as pollination strategies by insects or wind. This approach successfully revealed consistent mathematical patterns in floral design, providing new insights into the relationship between structure and biological function. This study shows that quantitative approaches can increase precision in the analysis of flower morphology, while providing a new tool for exploring the evolutionary dynamics of plants. This method can be applied to cross-disciplinary research involving morphology, genetics and plant ecology.
