ANALISIS PENGARUH POROSITAS PADA UJI KUAT TEKAN UNIAKSIAL TERHADAP KUALITAS BATUGAMPING KLITIK DAN BATUPASIR KARBONATAN KEREK DENGAN PENDEKATAN REGRESI NON LINIER EKSPONENSIAL DAERAH PANDEAN, KECAMATAN MANTINGAN, KABUPATEN NGAWI, PROVINSI JAWA TIMUR

Abstract

The utilization of rock mining resources is very taken into account in development. The potential of mining material resources in Karanganyar Village, Karanganyar Subdistrict, Ngawi Regency, East Java Province is quite calculated. To determine the quality, research needs to be done on the determining factors of the quality of the rocks used, among others; porosity, permeability, and UCS. To determine how much influence the strong press test is performed using exponential non linear regression analysis. Porosity is classified as negligible – fair, permeability is relatively good – very good; the resources in the research area are classified as directed resources with rock strength classified as very weak - moderate; low – medium quality. The results of the analysis of porosity influence on the value of press strong test results showed significantly up to 81,8% with conclusives that implicated each other and declared valid.

Keywords: Regression, Porosity and compression test.
