Meningkatnya suatu proses produksi industri kaca dapat berpengaruh pada
meningkatnya jumlah limbah yang di hasilkan. Banyak penelitian yang telah di
lakukan untuk memanfaatkan limbah botol kaca secara optimal. Serbuk kaca
digunakan karena memiliki potensi sebagai material pozzolan. Perencanaan
campuran beton menggunakan Metode ACI 211.1-91. Benda uji menggunakan
silinder dengan ukuran 10 cm x 20 cm. Benda uji yang digunakan pada penelitian
ini sebanyak 10 benda uji pervariasi bahan tambah serbuk kaca (2%), (4%), dan
beton kontrol dengan variabel pengujian pada umur 7 hari dan 28 hari. Dari hasil
penelitian diperoleh kuat tekan rata-rata beton normal dan beton serbuk kaca
dengan variasi (2%) dan (4%) pada umur 7 hari sebesar 20,21 MPa, 18,91 MPa,
dan 16,89 MPa. Kuat tekan rata-rata beton normal dan beton serbuk kaca dengan
variasi (2%), dan (4%) pada umur 28 hari sebesar 29,40 MPa, 28,30 MPa, dan 21,53
MPa. Dari hasil pengujian diperoleh nilai rata-rata modulus elastisitas pada beton
normal sebesar 21774,87 MPa, beton serbuk kaca (2%) dan (4%) sebesar 22552,52
MPa dan 18694,15 MPa. Berdasarkan hasil pengujian dan perhitungan diperoleh
nilai perbandingan kuat tekan rata-rata beton normal dan beton serbuk kaca. Pada
umur 7 hari nilai perbandingan kuat tekan rata-rata yang diperoleh antara beton
serbuk kaca variasi 2% dengan beton normal lebih besar 6,43% dari kuat tekan
beton serbuk kaca variasi 2% dan nilai perbandingan kuat tekan rata-rata yang
diperoleh antara beton serbuk kaca variasi 4% dengan beton normal lebih besar
16,43% dari kuat tekan beton serbuk kaca variasi 4%. Pada umur 28 hari nilai
perbandingan kuat tekan rata-rata yang diperoleh antara beton serbuk kaca variasi
2% dengan beton normal lebih besar 3,74% dari kuat tekan beton serbuk kaca
variasi 2% dan nilai perbandingan kuat tekan rata-rata yang diperoleh antara beton
serbuk kaca variasi 4% dengan beton normal lebih besar 26,77% dari kuat tekan
beton serbuk kaca variasi 4%.

The improvement of a glass industrial production process can affect the increase in the amount of waste generated. Many studies have been in do to make optimal use of glass bottle waste. glass powder used because it has potential as a pozzolanic material. Planning concrete mix using the ACI 211.1-91 method. Test object using cylinder with a size of 10 cm x 20 cm. Test objects used in research In this study, there were 10 test objects for variations in glass powder added (2%), (4%), and control concrete with test variables at the age of 7 days and 28 days. From result The research obtained the average compressive strength of normal concrete and glass powder concrete with variations (2%) and (4%) at the age of 7 days of 20.21 MPa, 18.91 MPa, and 16.89 MPa. The average compressive strength of normal concrete and powdered glass with variations (2%), and (4%) at the age of 28 days were 29.40 MPa, 28.30 MPa, and 21.53 MPa. From the test results obtained the average value of the modulus of elasticity in concrete normal is 21774.87 MPa, glass powder concrete (2%) and (4%) is 22552.52 MPa and 18694.15 MPa. Based on the test results and calculations obtained the comparison value of the average compressive strength of normal concrete and glass powder concrete. On the age of 7 days the value of the average compressive strength ratio obtained between concrete glass powder variation of 2% with normal concrete 6.43% greater than the compressive strength 2% glass powder concrete and the average compressive strength ratio obtained between the variation of 4% glass powder concrete with normal concrete is greater 16.43% of the compressive strength of glass powder concrete with a variation of 4%. At the age of 28 days the value of the ratio of the average compressive strength obtained between the variation of glass powder concrete 2% with normal concrete 3.74% greater than the compressive strength of glass powder concrete variation of 2% and the value of the average compressive strength ratio obtained between concrete 4% variation of glass powder with normal concrete 26.77% greater than the compressive strength 4% variation of glass powder concrete.
