Penggunaan beton yang semakin meningkat tiap tahunnya, memaksa manusia untuk terus mengeksploitasi sumber daya alam demi tercapainya kebutuhan tersebut. Di sisi lain, limbah akan terus bertambah seiring pertumbuhan penduduk, seperti limbah kaca dan pelepah pisang. Limbah kaca dapat digunakan sebagai alternatif lain untuk agregat halus karena mengandung SiO2, NaO2, dan CaO lebih dari 70%. Abu pelepah pisang memiliki potensi bahan tambah alternatif kuat tekan beton karena mengandung silika sebesar 52,72%. Penelitian ini dilakukan di Laboratorium Konstruksi dan Bahan Bangunan Program Studi Teknik Sipil Universitas Syiah Kuala. Faktor air semen yang dipakai adalah 0,52 yang didapatkan dari mix design. Variasi penggunaan limbah kaca yang diuji adalah 5%, 10%, dan 15%, serta variasi penggunaan abu pelepah pisang adalah 0%, dan 2%. Metode analisis pada penelitian ini menggunakan metode Analysis of Variance (ANOVA). Dari hasil penelitian diperoleh kuat tekan pada variasi beton normal sebesar 32,38 MPa. Pada subtitusi 0% limbah kaca dan penambahan 2% abu pelepah pisang diperoleh nilai kuat tekan 33,15 MPa. Pada subtitusi 5% limbah kaca dan penambahan 0% abu pelepah pisang diperoleh nilai kuat tekan 37,47 MPa. Pada subtitusi 5% limbah kaca dan penambahan 2% abu pelepah pisang diperoleh nilai kuat tekan 39,02 MPa. Pada subtitusi 10% limbah kaca dan penambahan 0% abu pelepah pisang diperoleh nilai kuat tekan 35,97 MPa. Pada subtitusi 10% limbah kaca dan penambahan 2% abu pelepah pisang diperoleh nilai kuat tekan 37,21 MPa. Pada subtitusi 15% limbah kaca dan penambahan 0% abu pelepah pisang diperoleh nilai kuat tekan 32,52 MPa. Pada subtitusi 15% limbah kaca dan penambahan 2% abu pelepah pisang diperoleh nilai kuat tekan 36,62 MPa. Kuat tekan tertinggi diperoleh pada subtitusi 5% limbah kaca dan penambahan 2% abu pelepah pisang dengan rasio peningkatan kuat tekan terhadap beton normal sebesar 20,51%.

The use of concrete is increasing every year, forcing humans to continue exploiting natural resources to meet these needs. On the other hand, waste will continue to increase as the population grows, such as glass waste and banana fronds. Glass waste can be used as another alternative for fine aggregate because it contains SiO2, NaO2, and CaO more than 70%. Banana leaf ash has the potential to be an alternative additive for concrete compressive strength because it contains 52.72% silica. This research was conducted at the Construction and Building Materials Laboratory of the Civil Engineering of Syiah Kuala University. The water cement ratio used was 0.52 which was obtained from the mix design. The variation of the use of glass waste tested was 5%, 10%, and 15%, and the variation of the use of banana leaf ash was 0%, and 2%. The analysis method in this research used Analysis of Variance (ANOVA) method. The results showed that the compressive strength of normal concrete variation was 32.38 MPa. In the substitution of 0% glass waste and the addition of 2% banana leaf ash, the compressive strength value is 33.15 MPa. In the substitution of 5% glass waste and the addition of 0% banana leaf ash, the compressive strength value is 37.47 MPa. In the substitution of 5% glass waste and the addition of 2% banana leaf ash, the compressive strength value is 39.02 MPa. In the substitution of 10% glass waste and the addition of 0% banana leaf ash, the compressive strength value is 35.97 MPa. In the substitution of 10% glass waste and the addition of 2% banana leaf ash, the compressive strength value is 37.21 MPa. In the substitution of 15% glass waste and the addition of 0% banana leaf ash, the compressive strength value is 32.52 MPa. In the substitution of 15% glass waste and the addition of 2% banana leaf ash, the compressive strength value was 36.62 MPa. The highest compressive strength was obtained in the substitution of 5% glass waste and the addition of 2% banana leaf ash with an increase ratio of compressive strength to normal concrete of 20.51%.
