Until now, especially in the forestry and plantation sectors, the mass provision of seeds still uses polybags made of plastic, even though on the other hand, large quantities of wetland waste are available which can be used as raw material for making environmentally friendly organic pots. The aims of this study were: 1) To analyze the physical and mechanical properties of organic pots from galam bark waste, water hyacinth and manure based on the type of adhesive, 2) To obtain the best composition and type of adhesive for developing organic pots. The research method used a completely randomized design Factorial with 2 factors where Factor A consisted of 4 levels of treatment which was the composition of galam skin waste, water hyacinth and organic fertilizer and Factor B consisted of 2 levels, namely the type of adhesive with 3 replications, so the number of samples needed a total of 24 samples. Tests for physical and mechanical properties were carried out at the ULM Faculty of Forestry Workshop and the Forest Product Technology Laboratory, Faculty of Forestry, Lambung Mangkurat University. The results showed that the water content of the organic pot of galam bark waste, water hyacinth and manure with tapioca and sago adhesives was the best in the A1B1 treatment, namely 14.51%, the best organic pot water absorption was in the A1B1 treatment, namely 123.69%, the A4B1 treatment. has the best average density of 1.712 gr/cm3. The best organic pot dry weight average value was found in the A3B1 treatment, which was 261.48 gr and the best organic pot side thickness was 1.75 cm. The best organic pot flexural toughness (MOE) was in the A1B1 combination treatment, namely 8174.38 kgf/cm2, while the best fracture toughness (MOR) and met SNI standards (min 80 kgf/cm2) in the A1B1 treatment combination, namely 83.23 kgf/cm2.
