Abstract

Telah dibuat ekosemen dari bahan abu sampah organik dan abu cangkang kerang. Sampah organik dibakar dengan insinerator pada suhu 1000oC. Abu cangkang kerang dipanaskan dengan furnace pada suhu 700oC. Hasil pengujian komposisi awal XRD (X-Ray Diffraction), Abu sampah organik mengandung 69,7% CaCO3; 12,1% KCl; 4% Cd0.15Gd0.85; 3% SiO2; 8,1% Fe ( Se0.5Te0.5) dan 3% Al2ErGe2, Abu cangkang kerang mengandung 100% CaCO3. Ditentukan tiga variasi jumlah komposisi Abu sampah:Abu cangkang kerang yaitu Ekosemen A (58,2%:40%); Ekosemen B (49,1%:49,1%) dan Ekosemen C (54,01%:44,09%). Sebagai variabel kontrol digunakan Semen Portland jenis OPC (Ordinary Portland Cement) merek ‘Semen Gresik’. Dilakukan pengujian fisika yaitu kuat tekan mortar dan densitas serbuk. Pengujian XRD dilakukan untuk mengetahui komposisi kimia dari ekosemen. Dari hasil pengujian fisika didapat ekosemen B paling mendekati nilai ‘Semen Gresik’ OPC yaitu kuat tekan 3 hari (7,2 kg/cm2) dan densitas serbuk (2,535 gr/ml).
