Fraksinasi Ekstrak Metanol Buah Parijoto (Medinilla speciosa Blume) dengan Pelarut Metanol, Etil Asetat, dan N-Heksana
Parijoto fruit (Medinilla speciosa Blume) is an endemic fruit around Mount Muria, Kudus, Central Java. The native people utilize Parijoto as traditional herbal medicine. Those utilization due to its metabolite compounds, such as tannin, flavonoid, fenolic, terpenoid, etc. In order to utilize Parijoto fruit properly, it is necessary to have an appropriate extraction and fractination method. So, the bioactive compounds of Parijoto fruit can be optimally extracted. The objective of this study is to obtain fractions of Parijoto fruit using three different solvent, methanol, ethyl acetate, and n-hexane. This study perform maceration as extraction method and liquid-liquid fractination to obtain the fractions. The dry simplicia yield was 85.49%. The maceration result was in the form of a blackish red green liquid with 67.45% yield. The methanol fraction was a thick blackish red liquid with 45.4% yield. While, the ethyl acetate fraction was a slightly fibrous viscous liquid with pinkish milk brown colour and 22.8% yield. On the other hand, the n-hexane fraction was a greenish viscous liquid with 13.8% yield. The highest yield is the result of fractination with methanol as a solvent because it is the most polar among others in this study. The solvent polarity is greatly affects the yield of fractination from natural product materials. In this study, the order of Parijoto yield from the highest to the lowest is methanol fraction, ethyl acetate fraction, and the last is n-hexane fraction.

Effects of An Isotonic Medinilla Speciosa During and After Exercise
International Journal of Exercise Science 16(2): 1269-1283, 2023. Maintaining an adequate fluid balance is crucial during extended physical activity. It is currently unknown how drinking an isotonic medinilla speciosa beverage affects the autonomic regulation of heart function during and after exercise. The purpose of this study is to examine how drinking isotonic beverages affects heart rate variability (HRV) during and after intense exercise. A maximal exercise test to assess protocol loading, a control group, and an experimental group were all carried out by twenty-one young man (19.3 ± 1.2 years) over the course of three distinct protocols, with a 48-hour break in between each stage. The protocol called for 10 minutes of rest with the subject lying down, 90 minutes of treadmill work at 70% of one\u27s maximum oxygen uptake, and 60 minutes of rest in the dorsal decubitus position. In the control group, no rehydration beverages could be consumed. No matter the level of hydration, alterations in the sympathetic nervous system (SNS) and the parasympathetic nervous system (PSNS) were seen, showing an increase in the former and a reduction in the latter. Hydration with isotonic solutions during recovery causes considerable alterations in cardiac autonomic regulation, hastening the recovery of the linear HRV index. Exercise-induced HRV was not significantly impacted by isotonic hydration, however it does speed up the recovery of linear indices after exercise

Abstract
The objective of this study is to determine the optimum condition of lactic acid fermentation with various concentrations of substrate and inoculum, which derived from the utilization of banana peel waste as substrate and Lactobacillus casei as inoculum. Response surface methodology (RSM) was used in this study. Variable optimization was conducted by Central Composite Design (CDC) with RSM to determine the optimum point of lactic acid fermentation variable. Those step used 13 groups with independent variable in the form of substrate concentrations (X1:2.5; 5; 7.5% w/v) and inoculum concentrations (X2: 2, 4, 6% v/v) to decide the optimum point of variable in the fermentation process. Fermentation was performed in a batch system with 100 mL media in a fermenter of 250 mL Erlenmeyer flask. The culture was incubated at 150 rpm and 37 °C for 72 hours.The result of lactic acid was used to determine the optimum point of variable in fermentation. The results showed that the yield from the fluor making process of banana peel was 23.02% with chemical characteristics of starch content, total sugar, total acid, and crude fiber were 5.35; 1.36; 0.61; and 1.54% w/w, respectively. The optimum concentration of substrate and inoculum concentration, 4.71% and 6.61%, resulted in optimum biomass concentration of 5.99 g/L, while the optimum point of X1 and X2 variables with substrate and inoculum concentration of 4.31% and 4.64% yielded optimum lactate acid concentration of 7.06 g/L, which is the best production of lactic acid in this study.
