Abstract
Kabupaten Grobogan yang berada di antara dua Pegunungan Kendeng memiliki sumber batugamping yang cukup dapat diandalkan, meskipun sumbangan dari sektor pertambangan dan penggalian dalam pembentukan Produk Domestik Regional Bruto (PDRB) hingga saat ini masih relatif kecil. Hal tersebut disebabkan adanya beberapa kendala seperti cara penambangan, cara pengolahan hasil dan sumber daya manusianya. Kondisi seperti ini sangat memungkinkan terbukanya kesempatan bagi investor untuk menanamkan modalnya guna mengelola batugamping secara optimal. Potensi sumberdaya batugamping di Kabupaten Grobogan memiliki jumlah yang besar yaitu 112.730.937.707 ton. Potensi sumberdaya batugamping terindentifikasi di 16 Kecamatan, yaitu Kecamatan Klambu, Brati, Grobogan, Tawangharjo, Wirosari, Ngaringan, Tanggungharjo, Kedungjati, Gubug, Karangrayung, Penawangan, Toroh, Geyer, Pulokulon, Kradenan, dan Gabus. Kegiatan pertambangan batugamping sudah dilakukan oleh 19 badan usaha pemegang IUP, yang mana 15 badan usaha pemegang IUP Operasi Produksi dan 4 badan usaha pemegang IUP Eksplorasi. Pemanfaatan batugamping di Kabupaten Grobogan selama 4 tahun terakhir ( 2010, 2011, 2012, 2013 ) tercatat sejumlah 2.897.103 ton. Penyusunan neraca sumberdaya batugamping di Kabupaten Grobogan mengikuti Petunjuk Teknis Neraca Sumberdaya Alam Spasial Nasional Buku 4 Penyusunan Sumberdaya Mineral dan Batubara Spasial tahun 2011. Tahapan penyusunan inventarisasi potensi sumberdaya batugamping di Kabupaten Grobogan, inventarisasi ini menjadi data sumberdaya awal yaitu aktiva setelah dikalikan dengan harga jual batugamping pada saat ini. Pemanfaatan atau produksi batugamping akan mengisi kolom pasiva setelah dikalikan dengan harga batugamping saat ini. Nilai aktiva yang sudah ada kemudian dikurangi dengan nilai pasiva untuk mendapatkan nilai saldo akhir neraca sumberdaya batugamping. Dari hasil penelitian neraca serta potensi sumberdaya batugamping di Kabupaten Grobogan didapat nilai aktiva sebesar Rp.343.962.506.783.169,- dan pasiva sebesar Rp.8.839.585.925,- didapat saldo akhir sumberdaya batugamping sebesar Rp.343.953.667.197.244,- pada tahun 2014. Dari hasil ini dapat dilihat peningkatan potensi di sektor usaha pertambangan batugamping dalam peningkatan pendapatan asli daerah di Kabupaten Grobogan bila di kelola dengan baik dan benar. Kualitas batugamping di Kabupaten Grobogan memiliki nilai komposisi kimia CaO = 51,66% - 54,79%, MgO = 0,45% - 2,77%, Fe2O3 = 0,02% – 0,13%, Al2O3 = 0,10% - 4,04%, dan SiO2 = 0,74% - 3,06%. Potensi sumberdaya batugamping tidak lepas dari pemanfaatan batugamping itu sendiri, beberapa pemanfaatan batugamping memiliki syarat mutu batugamping tertentu, pemanfaatan akan menyesuaikan dari nilai kualitas batugamping yang ada. District Grobogan which is located between two ridges kendeng having a source of considerable limestones reliable, although a contribution from mining and quarrying sector in the formation of regional Gross Domestic Product ( GDP ) until now is still relatively small. It is caused by the presence of some obstacles such as the mining method, in the manner of processing results and human resources. These condition is very possible transparency opportunity for investors to invest its capital in order to manage limestones optimally. Limestones resources potential in the district Grobogan having large amount that is 112.730.937.707 tons .The potential limestones resources that indentified in 16 sub-district, Which is sub-district Klambu, Brati, Grobogan, Tawangharjo, Wirosari, Ngaringan, Tanggungharjo, Kedungjati, Gubug, Karangrayung, Penawangan, Toroh, Geyer, Pulokulon, Kradenan, and Gabus. Limestones mining activities have been done by 19 business entities IUP holders , which 15 business entities holders IUP Production Operation and 4 business entities holders IUP Exploration .The production of limestones in the district Grobogan during the last 4 years ( 2010 , 2011 , 2012 , 2013 ) recorded a number of 2.897.103 tons. The preparation of the balance limestones resources in the district Grobogan following instructions technical the balance of spatial natural resource book 4 the preparation of national coal and mineral resources of the spatial 2011. Steps of preparing an inventory of potential limestones resources in the district Grobogan , inventory is the beginning of this being the data limestones resources assets after multiplied by the selling price of the limestones at the moment. Utilization or production of limestones will be filling columns of liabilities after multiplied by the price of limestones. The value of assets who was then reduced by the value of liabilities to get the end of the balance limestones resources value. Of research results as well as the potential resources balance of limestone in Grobogan had assets amounting to Rp. 343.962.506.783.169,- and liability of Rp 8.839.585.925,- acquired balance end of limestone resources amounting to Rp. 343.953.667.197.244,- by 2014. From this result can be seen increasing the potential within business sector mining limestones in increasing local revenue in District Grobogan if properly managed. The quality of limestones in District Grobogan having value chemical composition CaO = 51,66% to 54,79% , MgO = 0,45% to 2,77% , Fe2O3 = 0.02% to 0.13% , Al2O3 = 0.10% to 4,04% , and SiO2 = 0,74% to 3,06% .Limestones potential resources not separated from the utilization of limestones itself, limestones having some utilization of quality requirements certain limestones, expected to adjust the utilization of of the value of the quality of existing limestones .
