        abstract = {Currently, reconstruction of many buildings in Indonesia has been developed for last year that requires to Portland cement in usage need. The Portland cement in used derived from high quality cement. The high quality kalsilutit in Jadi Area and its surrounding, Jatirogo Sub district, Tuban Regency, East Java Province was studied by X-Ray Flourence (XRF) analysis. The aimof study is determinate the percentage of CaO and MgO also to identify the feasibility of limestone as main material for Portland cement. There were two samples of Paciran Formation were analyzed. Based on result of analysis, the percentage of CaO and MgO on those sample such as 39,25\% and 1,584\%, where as on the other sample is about 50,16\% dan 0?69\%. According to those result, both samples are not appropriate in criteria for Portland Cement main material = Meningkatnya pembangunan di Indonesia belakangan ini mendorong akan kebutuhan akan semen Portland juga semakin tinggi. Semen Portland yang digunakan tentunya berasal dari semen yang berkualitas. Kualitas kalsilutit daerah Jadi dan sekitarnya, Kecamatan Jatirogo, Kabupaten Tuban, Provinsi Jawa Timur akan diteliti dengan menggunakan analisis XRF (X-Ray Flourence). Penelitian ini untuk mengetahui prosentase CaO dan MgO serta untuk mengetahui kelayakan batugamping sebagai bahan baku semen Portland. Sebanyak dua contoh batugamping dianalisis dan diambil dari Formasi Paciran. Kandungan prosentase CaO dan MgO pada sampel yang dianalisis yaitu 39,25\% dan 1,584\%, pada sampel yang lain yaitu 50,16\% dan 0,69\%. Berdasarkan prosentase tersebut, kedua sampel tidak memenuhi kriteria batugamping untuk bahan baku semen.},
