4 CONCLUSIONS
From the results of research on the physical properties of peat soil in
Tulung Selan Ilir Village, Tulung Selapan District, it was found that the
original soil water content (w): 231.50% that this soil has a high water
content including the slighty absorbent, and the density yield (Gs ):
1.0767 gr/cm3 this value is below the range in the classification of
specific gravity of peat soil, with a pH value (acidity) of 3.18 this peat
soil is classified as highly peat. Based on fiber content, it has a value
of 64.8% including helmic peat. Meanwhile, the physical properties of
peat soil in Sumber Hidup Village, East Pedamaran District. Obtained:
Soil water content (w) 301.33% is included in the Moderately
Absorbent category with the ability to store and absorb water between
300% to 800%, specific gravity (Gs) is 0.4333%, and acidity (Ph) is 3
,93. Included in the highly acidic soil. And based on fiber content
