摘要
国家基础设施的经济增长和不断增长加剧了对建筑材料的需求，包括安居岩。安山岩石被广泛用于建筑基础、桥梁和道路灌溉渠。尽管如此，BPS 2013-2015的数据显示，苯甲岩的需求增加，同时苯甲岩生产商的数量减少，苯甲岩产量降低。为了确保国家发展进程的持续发展，需要进行新的安居岩保护区的搜索。在Gorontalo省的“A”地点进行了15次电阻率调查。通过使用RES2DINV软件的线性倒置，获得的伪电阻率数据为一个二维模型。接下来的二维模型将Rockworks15转换成三维模型。二维和三维模型分析显示,安山岩岩石储量在" A "的位置视电阻率下限公元198Ω最小。至于总数量数量为4084,375米3。这一结果表明，Gorontalo可能是消除印尼国家规模经济增长和基础设施发展的潜在提供者，导致了增加的材料需求，包括岩石。Andesitic岩石已经实用于创建建筑基础，桥开发就像公路开采一样。在这些增长过程中，不计其数的岩石行业和矿业都被脱机。因此，为了确保国家发展的持续发展，一种新的抗焦虑岩石岩石的探索，人们要求它。地理电阻电阻调查，15项调查线路已在“A”区域进行，戈隆塔洛省。使用RES2DINV软件，实现数据的非线性线性逆变模式已经实现。这台二维模型使用Rockworks15软件深入到三维模型中，是高度交织和扩展的。分析这些潜在的models节目a andesitic岩的界限和最低下储备at a位置resistivity是公元198Ω。。总准备金体积4,084,375米3。这种推导意味着，Gorontalo可以提供支持地方发展的岩石供应。
PERHITUNGAN VOLUME CADANGAN BAHAN GALIAN TAMBANG ANDESIT MENGGUNAKAN METODE RESISTIVITAS DIPOL-DIPOL DAN INTERPOLASI 3D DI LAPANGAN “A”
Pertumbuhan ekonomi dan gencarnya pembangunan infrastruktur secara nasional menyebakan kebutuhan bahan bangunan meningkat, termasuk Batuan Andesit. Batuan Andesit banyak dimanfaatkan untuk pembentukan pondasi bangunan, pembuatan jembatan serta pengaspalan jalan. Meskipun demikian, data BPS 2013-2015 menunjukkan bahwa peningkatan kebutuhan Batuan Andesit justru disertai dengan penurunan jumlah pengusaha batu andesit serta penurunan volume produksi batu andesit. Untuk menjamin keberlanjutan proses pembangunan nasional, perlu dilakukan pencarian cadangan Batuan Andesit baru. Survei geolistrik resistivitas telah dilakukan dengan 15 lintasan di lokasi “A” Provinsi Gorontalo. Data resistivitas semu yang diperoleh diolah menjadi model dua dimensi melalui inversi linear menggunakan perangkat lunak RES2DINV.
