Moisture Analysis Report.pdf

The provided content appears to be a collection of data related to thermogravimetric moisture analysis and drying kinetics observation. Here is a concise summary of the key information:

Thermogravimetric Moisture Analysis

Four sets of samples were analyzed: PT. KON (without pretreatment), PT. SB (with sodium bisulfite pretreatment), PT. AA (with ascorbic acid pretreatment), and PT. AS (with citric acid pretreatment).
Initial and final moisture content percentages were calculated for each sample set.
Average initial moisture content percentages:
+ PT. KON: 85.164%
+ PT. SB: 82.359%
+ PT. AA: 80.577%
+ PT. AS: 87.236%
Average final moisture content percentages:
+ PT. KON: 14.359%
+ PT. SB: 14.839%
+ PT. AA: 17.133%
+ PT. AS: 14.511%

Drying Kinetics Observation

The drying kinetics of samples without pretreatment (PT. KON) were observed based on a mass balance equation.
The observation was conducted over a period of time, with weight and moisture content measurements taken at regular intervals.
A moisture ratio (M. Ratio) was calculated for each time point, with values ranging from 1 (initial) to approximately 0.25 (final).
The data suggests a decrease in moisture content over time, with a corresponding decrease in weight.
