Abstract

ABSTRACTThe rain is the important thing in the human life. The higher rainfall can influence the public activities in many life area. They factors that influence rainfall are geographic position in a region and atmosphere phenomenon. Many atmosphere oscillation phenomenons are MJO, SAO, AO, QBO and ENSO. By knowing the phenomenon or oscillation of atmosphere are happened in a region can give the benefits for the human. Because of that the writer interested to do a researche about Analisys of Rainfall’s Daily Varian to Determine Atmosphere Oscillation Variation in Padang by using detailed result of rainfall in Padang on periode 2002-2011. This researche is a descriptive researche the data are used in this researche is the detailed result of daily rainfall in Padang from BMKG Tabing that have been taken from 2002 to 2011. The determination of rainfall’s variation can be proceed by using exel program and determination of oscillation manner can be determinate by using WWZ program an serfer 7. Based on analisys of rainfall’s data are gotten that highest rainfall’s happened in March and September while oscillation manner are gotten that they are oscillation of daily atmosphere or MJO, seasonal oscillation (SAO), annual oscillation (AO) and quasi biennial oscillation (QBO). Dominant oscillation manner was happened in Padang is the atmosphere oscillation type MJO that 25 times happen in range of time 2002-2011. Keywords:  Rain, oscillation, phenomenons of atmosphere

Abstract

Jorong Koto Baru Nagari Aie Dingin Kabupaten Solok is predict has mineral resources. The research to find deposit of several minerals have not be done. The purpose of the investigation is to identify any minerals contained in the Jorong Koto Baru based on chargeability value by Induced Polarization (IP) Geoelectrical method and distribution of minerals there. This research instrument is ARES (Automatic Resistivitymeter) to get data of apparent chargeability on the site. Data is collected and then be interpretated by Smoothness-Constraint Least Squares inversion. Data interpretation shows the actual value of chargeability and then be compared table of chargeability minerals and rocks. The result show that there are Graphite, Chalcophyrite, Copper, and Galena. Mineral Graphite (carbon compounds) are found with a thickness of 12.75 m, 43.4 m and 56.15 m. Mineral Chalchophyrite (dominated by copper element) was found with a thickness of 43.78 m and 6.15 m. Mineral Copper (copper element) was found with a thickness of 10.5 m, 15.42 m, 6.52 m and 40.1 m, while mineral Galena (lead sulfide) was found with a thickness of 2.78 m, 9.73 m, and 4.35 m. Conclusion the area has some potential mineral resources.
