out at the Soil Mechanics Laboratory, Faculty of Engineering,
Tridinanti University, Palembang. Laboratory work begins with
preparatory work, namely providing soil samples and tools and
materials to be used in testing. The tests carried out are: Testing the
physical properties of peat soil, compaction test, and CBR test.
1.1 Physical Properties of Peat Soil
To determine the physical properties of the peat soil used in this study,
laboratory tests were used. This is done to determine the
characteristics and properties of the soil to be tested. The physical
properties of the soil used in the laboratory are as follows: Water
content test, specific gravity test, pH test, and fiber content test.
Table 1. Classification of Peat Soil based on Water Content (ASTM
D4427-84).
Type Water Content (%)
Extreme > 1500
High 800-1500
Moderate 300-800
Low <300
Table 2. Classification of Peat Soil based on pH (ASTM D4427-84).
Type pH
Highly Acidic < 4.5
Moderately Acidic 4.5–5.5
Slightly Acidic > 5.5 - < 7
Basic ≥ 7

Table 3. Classification of Peat Soil based on fiber Content (ASTM
D4427-84).
Type Fiber Content (%)
Fibric peat > 67
Helmic peat 33-67
Sapric peat < 33
