Pada penelitian ini seiring perkembangan jaman didunia kontruksi salah satunya dalam inovasi teknologi beton ditemukan pemanfaatan abu tempurung kelapa dalam pembangunan maupun infrastruktur dan memicu inovasi dalam bidang rekayasa struktur bahan. Oleh karena itu penggunaan abu tempurung kelapa sebagai komponen tambahan dalam komposisi pembuatan beton terhadap bahan tambah semen. Penelitian ini adalah untuk mengetahui bagaimana pengaruh abu tempurung kelapa sebagai bahan tambah terhadap kuat tekan beton dan Seberapa besar presentase kenaikan dan penurunan kuat tekan beton dengan tambahan abu tempurung kelapa. Pengujian ini menggunakan benda uji kubus berumur 28 hari dengan total benda uji beton sebanyak 120 sampel, dengan setiap variabel sampel beton masing-masing berjumlah sebanyak 30 sampel. Dari hasil penelitian ini diuji secara statistik distribusi normal menggunakan aplikasi IBM SPSS Statistic 26 hingga memperoleh nilai kuat tekan beton normal 309,086 kg/cm². kuat tekan beton campuran ATK 2% sebesar 325,873 kg/cm². kuat tekan beton campuran ATK 2,5% sebesar 252,824 kg/cm². kuat tekan beton campuran ATK 3% sebesar 186,913 kg/cm². Kuat tekan beton campuran ATK 2% mengalami kenaikan 5,44% terhadap beton nornal. Kuat tekan beton campuran ATK 2,5% mengalami penurunan 18,20% terhadap beton normal. Kuat tekan beton campuran ATK 3% mengalami penurunan 39,52% terhadap beton normal.

In this research, along with the development of the times in the world of construction, one of which is in concrete technology innovation, it was found that the use of coconut shell ash in development and infrastructure triggered innovation in the field of structural engineering materials. Therefore, the use of coconut shell ash as an additional component in the composition of making concrete against cement additives. This research aimed to find out how the effect of coconut shell ash as an additional material on the compressive strength of concrete and how large the percentage of increase and decrease in compressive strength of concrete with the addition of coconut shell ash. This test used 28-day-old cube specimens with a total of 120 concrete specimens, with each concrete sample variable totaling 30 samples. The results of this study were statistically tested for normal distribution using the IBM SPSS Statistic 26 application to obtain a normal concrete compressive strength value of 309.086 kg/cm². The compressive strength of the 2% ATK mixture was 325.873 kg/cm². The compressive strength of the 2.5% ATK mixture was 252.824 kg/cm². The compressive strength of the 3% ATK mixture was 186.913 kg/cm². The compressive strength of 2% ATK mix concrete has increased by 5.44% against normal concrete. The compressive strength of 2.5% ATK mix concrete decreased 18.20% against normal concrete. The compressive strength of 3% ATK mix concrete decreased 39.52% against normal concrete.
