The other water status parameters such as moisture content, leaf area index and leaf water potential
showed the same pattern with visual appearances based on (Figs. 3, 4 and 5). The fluctuation
of leaf water potential value during day 9 and 10 is due to instability of air flow distribution
in growth chamber. This hypothesis is supported by return of value starting by day 11. This proves
that those parameters have same pattern with texture analysis result and also visual appearances.
Based on comparison among texture analysis, visual appearance, moisture content, leaf area
index and leaf water potential, four critical control points have been classified as initial point which
occurred in first day of watering, wet point in day 3, semi-dry in day 5 which is the transition point
between dry and wet and finally dry point in day 8 (Ushada et al., 2006).
After observing and analysing critical control point in moss water status during 17 days of
monitoring, the data is recapitulated in 187 set data patterns for ANN model. The 136 set data were
used in training ANN prediction model, while the remaining was used in inspection data.
