Abstract

DOI: 10.17014/ijog.v7i4.146This paper is dealing with ore characteristics and fluid inclusion of the Moncong Bincanai, Biringbulu Subregency of Gowa Regency, South Sulawesi Province, Indonesia. The mineralization is a vein type, with the orientation of N170oE /65oSW, hosted in open-space filling within basalt. The mineralization consists of galena, sphalerite, chalcopyrite, and pyrite. Vein thickness ranges from 5 - 17 cm, showing a crustiform banding texture, with a sequence from outer to centre: quartz, carbonate (siderite), sulphide. The quartz displays primary growth textures such as comb, crystalline, saccharoidal, and colloform. Analytical methods applied include AAS and fluid inclusion microthermometry. Chemical composition of the vein indicates an average of Pb = 47.92%, Cu = 1.27%, Zn = 1.02%, and Fe = 9.46%, which shows a significant concentration of Pb. Fluid inclusion microthermometry results indicate a range of formation temperature of 240 - 250C and salinity of the responsible hydrothermal fluid of 2.1 - 2.5 wt.% NaCl eq. The deposit is categorized into low-sulfidation epithermal deposits, which was formed within a range of 410 - 440 m below paleosurface.

Abstract

The aim of vocational education is to produce employees who are ready to work, a characteristic of vocational education is through the implementation of apprenticeship. In the period 2010-2015 in Indonesia the labor force declined from vocational schools compared to senior high schools. This indicates the need for 21st century skill is called a tool for work, namely the skill to use Information and Communication Technologies (ICT). This article is intended to find out the relationship between apprenticeship and ICT in vocational students who carry out apprenticeship in the province of West Java. From the instrument distributed in 520 samples, it was found that there is a relationship between apprenticeship training and ICT through the value of Zcount = 7.16 Ztable = 2.58, with the coefficient of determination of (ry)2 = (0.315)2 = 0.0992. This shows that apprenticeship contributions affect ICT skill by 9.92% for students who carry out apprenticeship in the West Java province of Indonesia, while 90.08% is influenced by other factors.
