Abstract

Research has been carried out in Samangki Village which aims to analyze the potential of limestone resources using the Geoelectrical Resistivity Method with the Wenner-Schlumberger configuration. Data were collected at 801904.40-802051.05 NE and 9440758.03-9440548.93 SW for 3 lines along 120 m with 10 m electrode space in a track. Acquired data were processed using Microsoft Excel, Notepad, RES2DINV, ArcGIS, and Google Earth applications to produce resistivity cross-sections and other supporting maps. Based on data interpretation, it shows that the low resistivity zone is an alluvium deposit (Qac) with resistivity value of 17.58 to 170 Ωm; and the high resistivity zone indicates the presence of limestone which is part of the Tonasa Formation (Temt). The presence of limestone on line-1 with resistivity value of 326.00 to 931.90 Ωm at position(x) 60 to 90 m, in depth(y) 1.25 to 9.26 m as shallow area, and at position 40-45 m in depth 16 to 19.8 m as the deepest area. Then the limestone on line-2 is indicated as a subsurface karst tower with a resistivity value of 462.00 to 809.36 Ωm at position 30 to 50 m in depth 1.25 to 19.8 m. Limestone also located on the northeastern edge of line-3  with resistivity values of 431.00 to 739.66 Ωm at a position of 12.5 to 17.5 m in depth of 1.25 to 6.38 m. It proves that Samangki Village has large potential for limestone resources. This research need further geoelectrical study with broad coverage area and geochemical analysis for detail karst characterization

Abstract

The X-ray beam collimation test, voltage accuracy test, reproducibility test, and fourth is the X-ray beam output test (Half Value Layer) on the Mobile X-ray aircraft. This testing aims to determine the standards that have been set. Tests that have been carried out on the illumination and the difference between the collimation field of the beam and the X-ray beam show that the results obtained have passed the test on an X-ray aircraft. Both tests are in accordance with established standards. Reproducibility testing is carried out by measuring the radiation output (mGy) at the same settings repeatedly. The data shows a corrected mean of 0.075 mGy with a standard deviation of 0.0034, indicating that the X-ray aircraft has good reproducibility in producing consistent radiation output. The mobile X-ray unit tested had sufficient accuracy and reproducibility that complied with established standards and demonstrated the reliability of the device in clinical practice. X-ray beam output testing was carried out and a corrected HVL value was obtained which was greater than the test pass value. The results obtained are in accordance with established standards.

Abstract

Penelitian fokus pada pengujian biobriket dari komposisi arang tempurung kelapa, kulit kacang tanah, dan tinja sapi dengan perekat tepung kanji. Penelitian ini bertujuan untuk mengetahui kualitas briket yang meliputi parameter kerapatan, kadar air, kadar abu, dan nilai kalor berdasarkan standar SNI. Penelitian ini menggunakan metode karbonisasi untuk tempurung kelapa dan kulit kacang dan pada perlakuan bahan tinja sapi menggunakan metode tanpa karbonisasi. Hasil penelitian menunjukkan bahwa nilai kadar air, kadar abu dan nilai kalor optimal diperoleh pada sampel D masing-masing sebesar 3,5%, 1% dan 5483,26 kal/gram. Untuk pengujian nilai kerapatan briket dari rentang 0,58 gr/??3 sampai 0,77 gr/??3. Dari keseluruhan komposisi semuanya memenuhi standar SNI briket dengan sampel terbaik pada komposisi sampel D yang terdiri dari 45% tempurung kelapa, 30% kulit kacang tanah, 15% tinja sapi dan perekat sebanyak 10%.
