Abstract :
In general, the growth and development of the construction industry in Indonesia is quite rapid Almost 60% of the materials used in construction work are concrete (concrete) combined with steel (composite) or other types. Because of the vast role of concrete in the field of construction, many parties are looking for high quality concrete to produce a good infrastructure. The materials to be used in the manufacture must be carefully selected by considering the composition percentage to create high-quality concrete. Various materials used lately are often combined with added materials, including the use of waste. One example of waste that can be used is waste from hermit crabs. In this study the shellfish shell waste was added in a concrete mixture of 0%, 5%, 10%, and 15% by weight of cement with a testing time of 7 days, 14 days and 28 days. Testing is carried out with two stages of research. The first stage is material testing and the second stage is testing the specimen, namely the compressive strength and tensile strength of the concrete. Based on the results of the testing of the compressive strength and the tensile strength of the concrete the optimum percentage value of the addition of hermit crab waste is 10% with a 28 day treatment duration having a compressive strength of 26.421 MPa and a concrete split tensile strength of 1.910 MPa. These results indicate that the use of mixed ingredients of hermit crabs with a percentage of 10% in a concrete mixture can increase the compressive strength and split tensile strength on the concrete quality of K 300.
