KUALITAS BATUGAMPING TERUMBU SEBAGAI BAHAN BAKU SEMEN PORTLAND DAERAH NGLUYU DAN SEKITARNYA, KECAMATAN REJOSO, KABUPATEN NGANJUK, PROVINSI JAWA TIMUR
Kualitas Batugamping Terumbu Sebagai Bahan Baku Semen Portland Daerah Ngluyu dan Sekitarnya, Kecamatan Rejoso, Kabupaten Nganjuk, Provinsi Jawa Timur
Abstract
ABSTRAK
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 batu gamping di daerah Ngluyu dan sekitarnya, Kecamatan Rejoso, Kabupaten Nganjuk, 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 Klitik. Kandungan prosentase CaO dan MgO pada sampel yang dianalisis yaitu 29,19% dan 1,583%, pada sampel yang lain yaitu 42,91% dan 1,518%. Berdasarkan prosentase tersebut, kedua sampel tidak memenuhi criteria batugamping untuk bahan baku semen.Kata kunci: Portland, Ngluyu, batugamping, Klitik
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 limestone in Ngluyu Area and its surrounding, Rejoso Sub district, Nganjuk 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 Klitik limestone Formation were analyzed. Based on result of analysis, the percentage of CaO and MgO on those sample such as 29,19% and 1,583%, where as on the other sample is about 42,91% dan 1,518%. According to those result, both samples are not appropriate in criteria for Portland Cement main material.
