The paving block produced by Kampung KB Berdikari is a type of paving block made from plastic waste. This plastic waste is collected from the surrounding community, then converted into paving blocks. This plastic paving block has not gone through a quality testing process which causes its quality to only be based on assumptions. This study aims to design and manufacture a compression test equipment that will be used to analyze the compressive strength of plastic paving blocks based on SNI 03-0691-1996 paving block standards. The method used in this research is the case study method and the quantitative descriptive method which explains the results of testing the strength of paving blocks using a compression test equipment designed by the researcher. The compressive test equipment that has been made has dimensions of 1400 cm x 900 cm x 300 cm with the main frame material being ASTM A36 iron plate. The area of the compressive test surface is circular with a maximum area of 452.16 cm2 (d = 24 cm), and a maximum test chamber height of 25.3 cm. This compression test equipment uses a 50 Ton bottle jack and a 100 MPa Pressure Gauge as a device to press and measure the pressure of the test object. This device was calibrated with the JTT JT TOHSI INC 10 tf calibrator. The average result of the pressure force is 1 bar equivalent to 0.0296 tons on the pressure gauge. The finite element simulation results show that the mandated loading is ≤14.04 tons with a safety factor of 1.25. The results of testing the compressive strength of plastic paving blocks using a compression tester showed an average compressive strength of 3.2824 MPa. This figure does not meet the SNI 03-0691-1996 paving block standard.References
