This research combines kulim wood dust and coconut shell powder as a substitute for concrete materials. Ash from kulim sawdust has silicca properties. Meanwhile, coconut shell powder can be mixed in concrete. This study aims to determine the effect of using kulim sawdust ash as a partial substitution of cement and coconut shell powder waste as a partial substitution of fine aggregate on compressive strength and to determine the ideal proportion of the percentage variation of added ingredients. Concrete planning uses an experimental method that refers to SNI 03-2834-2000, SNI 03-1974-1990 and the Unisla Concrete Practicum Guidebook. With a total sample of 12 test objects with the quality plan K-225. The results of the normal concrete compressive strength test with an N code of 19.55 MPa. The results of testing the compressive strength of concrete with added materials with code A1 are 19.29 MPa. The results of testing the compressive strength of concrete with added materials with code B1 are 18.84 Mpa. The results of testing the compressive strength of concrete with added materials with code C1 are 18.46 MPa. Based on the results of the study it was concluded that the added ingredients of kulim wood powder ash and coconut shell powder did not significantly affect the compressive strength of concrete and the higher the added material value the lower the concrete compressive strength value and the lower the added material value, the higher the concrete compressive strength value.

Paving block is a building material composition made from a mixture of portland cement or other hydraulic adhesives, water and aggregate with or without other additives which do not reduce the quality of the concrete. This study aims to analyze the compressive strength of paving blocks from the utilization of local sand and palm shell waste. Palm shell waste is obtained from PT. Tapian Nadenggan who processes palm oil into palm oil. The large amount of waste can be used as an added ingredient in the manufacture of paving blocks. This research method is an experimental research, by making hexagonshaped paving blocks with a mold size of 20 cm wide, 12 cm side and 6 cm thick using estuary sand and palm oil shell ash waste with variations of 0%, 25%, 50%, 75%, 100%. The addition of ash from palm shell waste resulted in an effective compressive strength test at 28 days of age with the highest value at 50%, namely 17,64 MPa, then 25% variation, namely 17,38 MPa and 75% variation with a value of 16,03 MPa, classified as quality B can be used for parking lots. Meanwhile, the 100% variation with a yield of 11,03 MPa is included in grade D and can be used for garden.

“…All of them have increased water infiltration on paving blocks. [3] The addition of paper grains to the concrete mixture reduces the compressive strength of concrete (compared to normal concrete) and according to a journal entitled "Alternatives for Using Paper Mill Waste as a Partial Replacement for Cement (Cementitous) in "Concrete Making" in the journal uses the proportions added to the cement mixture in the concrete by 0%, 5%, and 10%. So the author concludes make the proportion less than 10% [4].…”

Infrastructure development is one of the important aspects of the progress of a country where most of the constituents of infrastructure are concrete. The most important constituent of concrete is cement because its function is to bind other concrete materials so that it can form a hard mass. The large number of developments using cement as a building material will leave quite a lot of cement bags.In this study, the authors conducted research on the effect of adding cement waste to the compressive strength of concrete. This study used an experimental method with a total of 24 test objects. The test object is in the form of a concrete cylinder with a diameter of 15 cm and a height of 30 cm and uses variations in the composition of the addition of cement waste cement as a substitute for fine aggregate, namely 0%, 2%, 4% and 6%. K200). The compressive strength test was carried out at the age of 7 days and 28 days.The test results show that the use of waste as a partial substitute for fine aggregate results in a decrease in the compressive strength of each mixture. at the age of 7 days the variation of 2% is 16.84 MPa, 4% is 11.32 MPa and for a mixture of 6% is 6.68 MPa. Meanwhile, the compressive strength test value of 28 days old concrete in each mixture decreased by ± 6 MPa. So the conclusion is cement cement waste cannot be used as a substitute for fine aggregate in fc 16.6 (K200) quality concrete because the value is lower than the specified minimum of 16.6 MPa.
