Abstract

Ball clay quality are derived from within the country is very variety and generally rather difficult to get raw materials as needed. This research used ball clay from the West Kalimantan and West Java area.Ball clay is one of the most important raw materials for the manufacture of fine ceramic. To get the ball clay raw materials in accordance with the standards it is necessary to processing of raw materials. Processing of ball clay in this research conducted by precipitation and filtration magnet. Testing of ball clay raw materials are : test chemical composition by wet methods (SNI. 15-0449-1989) and grain size of raw material (SNI.15-0578-1996). Ball clay that has been processed will be tested with the same method of SNI. Test results before and processed will be compared with a standard of quality ball clay(SNI, NGK, India) for fine ceramic materials. The test results of chemical composition and grain size ball clay raw material showed that samples from west kalimantan qualified for fine ceramic materials and samples from other areas did not meet the standards (SNI, NGK, India). ABSTRAKMutu ballclay yang terdapat di dalam negeri sangat beragam dan umumnya agak sulit mendapatkan bahan baku yang sesuai dengan kebutuhan. Pada penelitian ini digunakan ball clay yang berasal dari daerah Kalimantan Barat, Jawa Barat dan Jawa Timur. Ball clay merupakan salah satu bahan baku penting untuk pembuatan keramik halus. Untuk mendapatkan bahan baku ball clay sesuai dengan standar maka perlu dilakukan pengolahan bahan baku. Pengolahan ball clay dalam penelitian ini dilakukan dengan cara pengendapan dan penyaringan magnet. Pengujian terhadap bahan mentah ball clay meliputi : uji komposisi kimia dengan metode basah (SNI. 15-0449-1989) dan pengujian besar butir (SNI.15-0578-1996). Ball clay yang sudah diolah nantinya akan diuji dengan metode SNI yang sama. Hasil uji sebelum dan terolah akan dibandingkan dengan standar mutu ball clay untuk bahan keramik halus. Hasil uji dari komposisi kimia dan besar butir ball clay bahan mentah menunjukan bahwa sampel dari Kalbar memenuhi syarat untuk bahan keramik halus dan sampel dari daerah lainnya ternyata tidak memenuhi standar (SNI, NGK. India).

Abstract

Balai Benih Ikan (BBI) is an aquaculture located in Tanah Datar district. Thisaquaculture experiencing water resources shortage. New water resources are needed for the aquaculture. The interpretation of imaging resistivity showed that at BBI, water resources lies between 70 to 100 meter depth. Aquifer thickness varies between 5 to 25 meters and were found at observation points 40 to 125 meter. Water resources at BBI was predicted found on top of the hard rock and thick layer. Water resources interpreted that the used daily as water trap on the rock layer. This existing BBI water resources are not the potential aquifer. Therefore BBI has shortage of water resources. In the future, water resources for BBI is suggested to be taken from groundwater about (100 – 160) meter to the west.

Abstract

Kaolin is one of a very important raw material for fine porcelain ceramic production and the kaolin resources can be found in many places in Indonesia. Kaolin characteristic tests which include (chemical, physical, furnace, mineralogy, grain size) showed that the sample 1 and 2 do not meet the standard of porcelainceramic raw material. Fe2O3 concentrations of sample 1 and TiO2 concentrations of sample 2 were below SNI standard. In order to meet the SNI standard for isolator, post processing are required. These can further be important for the development of medium to high voltage isolator industries in Indonesia.

Abstract

Tampomas mountain areas can be divided 2 types of aquifer : volcanosediment aquifer and sediment aquifer. Volcano sediment aquifer is afree aquifer sedimentation, because there was not impermeable rockexisting under or bellow it, this aquifer also known as shallow or surfaceaquifer. Sediment aquifer is a depressed aquifer where the water flowalong the sandstone layer which covered by claystone and water flowthrough the pore. This sediment aquifer are deep aquifer. Ground waterat sumedang area can be divide as : ground water on volcanic quartersedimentation and ground water on consolidate rock.The type of water source at the reaserch area can be devide into 3 ways: Depressed water resources formed by land surface which is cuttingthe watter table, Shear water source which formed by the crack / shearstructure or sesar path, and contact water source which shown at thetertiery rock (impermeable) and quartery rock (permeable).This reaserch using geofisical methode Imaging Resistivity to resultinterpretation that on the south Tampomas Mountain predicted had 4aquifer potention resource (A,B,C,D), whith aquifer thickness vaariatedfrom (5-15)m, (30-50)m and more than 50 m. Several water sourcesurface cases found in this reaserch area at 20-30 m depth which predictas the water table. This indicated there are very large aquifer at 500 mlevel and assume this level as a potential places for ground water existat the south Tampomas mountain.

Abstract

Based on groundwater indication map, the area of Pengadegan district, PurbalinggaRegency, has low groundwater resources potential for both deep and shallowgroundwater.Investigation using resistivity showed that the potential water layers were found inthe eastern part of the Dam at B and C layers. The groundwater is shallow and thethickness of the aquifer is about 20 meter and extent horizontally up to 30 meter.Layer A and B in the western part of the Dam are possibly act as a water trap asthey lies above a compact layer E.To know the potential groundwater area it is suggested that further research andsurvey be done in the eastern part of the Dam.

Abstract

Ground water potential map showed that the Salimpaung in Tanah Datar District has very low water resources potential. Deep and shallow water resources were found in some places and in a limited area.Interpretation of imaging resistivity showed that water resources potential lies in P1 and P2 layers. This layers were found in 90 to 150 meters to the south of the mosque. The potential layer was found between 10 to 30 meter depth and thickness between 5 to 25 meter and lies in observation point between 50 – 125 meter. Water resources at layer P1, P2, P3 and P4 has medium to low potential and the water layers was interpreted as water trap above the rock layer. The other water resources potential were found at P5, P6 and P7, at 90 – 150 meter to the north of the mosque. The potensial aquifer lies beneath hard rock at depth 40 to 60 meter.

ABSTRAK Batu kapur merupakan bahan penting yang digunakan sebagai bahan campuran di industri pengolahan bijih besi. Penelitian ini dilakukan untuk mengetahui informasi tentang karakteristik batu kapur dalam negeri yang melimpah sehingga dapat digunakan untuk bahan campuran di industri pengolahan bijih besi. Untuk mengetahui  kemurnian batu kapur maka menggunakan standar BGS dan untuk mengetahui karakteristiknya untuk industri logam maka menggunakan standar literature dari industry logam dalam negeri, India dan ESDM. Kemurnian batu kapur menurut standar BGS maka sampel dari Sumatera, Jawa, Kalimantan dan Sulawesi umumnya sampel batu kapur menengah sampai tinggi (medium - high purity). Berdasarkan standar :  industri logam (besi), Industri di India dan literatur ESDM maka sampel dari jawa barat, jawa tengah dan  sumatera utara dapat digunakan sebagai  bahan campuran pada industri logam (besi). Umumnya sampel Batu kapur  dapat dipakai sebagai bahan baku campuran karena murni dan  untuk memenuhi standar industri diperlukan  proses pengolahan. Kata kunci : Batu kapur, pengujian, standar, karakteristik batu kapur.  ABSTRACT This research was conducted to find out information about the characteristics of domestic limestone. Limestone is an important material used as a mixture in iron ore processing industries. To find out the purity of limestone and to determine its characteristics for the metal industry using the BGS standard. To find out its characteristics for the metal industry, it uses literature standards from the domestic metal industry, India and ESDM (minister of energy and mineral resources). According to BGS standards : The purity of limestone from Sumatra, Java, Kalimantan and Sulawesi is generally medium to high purity. Based on standards: metal (iron) industry, Indian industry and ESDM literature : samples from West Java, Central Java and North Sumatra be used as a mixture in the metal (iron) industry. Generally, limestone samples can be used as raw materials because they are pure and to meet industry standards, processing is required. Key word : Limestone, testing, standard, limestone characteristic.
