In this research aims to study the leading waste sawdust is used all types of plant pots. By studying the appropriate ratio of sawdust per forming plaster as a planter and strong, which, compared to standard plaster products. Industrial standard, or TIS 2488 – 2553 (2010) The trial is divided into two parts: 1. moisture-density test and flexural resistance of rods and testing part 2: finding the proper ratio of sawdust per plaster to make plant pots. By studying the trial find moisture, density and tensile strength from test stick. Study of sawdust per aspect ratio 5 plaster is 0:100 (control variables) 5:95 15:85 30:70 and 45:55 which has test sticks cross section area is equal to 40x40 mm and a length equal to 160 mm and test out the resistance, flexural bending strength Tester set with cement mortar. From the test results, select an appropriate aspect to phlitkrathang tree diameter and height 5 inches equals 4 inches.The study found that every aspect has an average population density of the test stick with values in the range ± 0.008-0.938 ± 0.028 1.182 grams per cubic centimeter. The average percent moisture test sticks have a value in the range of 31.145-1.090 ± 27.247 ± 1.205 and average flexural resistance of test sticks at 0:100 (control variables) 5:95 15:85 and 30:70 equals 3.785 ± ± ± 0.100 1.840 3.046 0.513 0.215 ± 0.00 1.406 and Newton per square millimeter respectively. This is the ratio of 45:55 could not be moulded into test sticks. From the study can conclude that sawdust can be taken as a composite material in the phlitkrathang tree. It found that the ratio of sawdust per plaster 5:95, a ratio that is most appropriate to bring the sawdust used as composite materials applied to the phlitkrathang tree. Charge pressure resistance compared to most other ratios are sawdust used as composite material.
