| dc.description.abstract | Tea waste (LT) is one of the biomas produced from tea processing and has not been utilized optimally. Tea waste biomass can be processed into biopots as a planting medium. Efforts to improve the function and quality of tea waste biopots are carried out by adding blood clam shell flour (TCKD) as a filler. The adhesive used to strengthen the physical properties of the biopot is durian seed starch with a variety of solvents in the form of aquadest and eco-enzymes. This study aims to: (1) analyze the effect of the comparison of the composition of LT, TCKD and durian seed starch on the biopot produced; (2) analyze the effect of the addition of eco-enzyme on the quality of the biopots produced; and (3) analyze the quality of the biopots produced. This research consists of several stages, namely: preparation of raw materials, making biopots, analysis of physical properties, mechanical strength, and analysis of plant growth rate. The ratio of LT and TCKD used is 200:0; 180:20; 160:40; 140:60; 120:80; 100:100; 80:120. The best composition of biopot is a formulation of 100 g LT:100 g TCKD with eco-enzyme as a solvent. Biopots with aquadest as solvents have lower physical and mechanical properties compared to eco-enzymes. Eco-enzymes improve the quality of biopots by strengthening the bonds between particles and providing nutrients for plants because they contain nitrogen, phosphorus, and potassium, while aquadest is less optimal because it does not contain organic compounds to improve the quality of biopots. The yield of biopot density ranged from 0,43-0,64g/cm3 and water absorption ranged from 60,93-76,27%. The analysis of pH values showed that the resulting biopots had soil pH ranging from 6,10-6,59 and was in accordance with soil acidity. The addition of TCKD up to 100 g increased the compressive strength and hardness of biopots with the results of analysis being 1,57-6,05 MPa and 0,049-0,116 MPa, respectively. However, the excessive addition of clamshell flour (120 g) decreases the hardness value, due to the imbalance of the adhesive composition with the raw material and increased porosity | en_US |
