Penerapan Sistem Informasi Untuk Manajemen Data Mineral

Mineral Information System (SIM) is an added value and integrated database system for mineral in Indonesia concerning with the availability of mineral resources, which encompasses the entire aspects of mineral commodity such as geology, mining, geography, exploration, exploitation, processing technology,statistics and its developments. The technologies used in the SIM development are appropriate technology, open platform, Visual Programming using Rapid Application Development tools, and Relational Database Management System (RDBMS). The SIM technology enables users to illustrate and display someinformations regarding to mineral resources easily and rapidly, i.e. local governments, investors, or persons who are interested in mining or mineral development. The SIM technology is benefit for decision makers to support a regulation or urban planning. In this paper, it will be described about visualization model of SIM in application desktop form

Aplikasi Teknologi Eksplorasi untuk Memahami Kondisi Air Tanah di Daerah Padang Luas Kabupaten Tanah Laut

Groundwater is water that comes from the ground. Groundwater comes from rain, snow, sleet, and hail that soaks into the ground. The water moves down into the ground because of gravity, passing between particles of soil, sand, gravel, or rock until it reaches a depth where the ground is filled, or saturated, with water. Groundwater is stored in the ground in materials like gravel or sand. Water can also move through rock formations like sandstone or through cracks in rocks. Groundwater is one of solution to overcome a problem of the need of drinking water in the PadangLuas Area, because the availability of surface water is not enough. The objective of research is finding out characteristic and condition of ground water in PadangLuas, Tanah Laut district. To meet the objective, it was applied method of geophysical technology, namely electrical resistivity method by injecting current into the ground through current electrodes that are grounded at the earth's surface and measuring the difference of the electrical potential between the potential electrodes. Based on data processing, modeling and interpretation, it was gained result concerning the existence of aquifer in PadangLuas area that is predicted to occupy between 30 – 60 meter and 70 – 120 meter depth

INTERPOLATION METHODS FOR SEA SURFACE HEIGHT MAPPING FROM ALTIMETRY SATELLITES IN INDONESIAN SEAS

Altimetry satellite data, has a very low spatial resolution for using in determine fishing ground area. With very low spatial resolution is required interpolation method that can mapped Sea Surface Height (SSH) with a good result. SSH data from Global Near Real Time from AVISO, mapped in geographic projection and interpolated with Inverse Distance Weighting (IDW) and Ordinary Krigging method. This interpolation method are expected to know which the good method for mapped SSH data in resulting better information. The results of statistical calculation shows that RMSE value and standar deviations from kriging method is smaller than IDW method

STUDY ON POTENTIAL FISHING ZONES (PFZ) INFORMATION BASED ON S-NPP VIIRS AND HIMAWARI-8 SATELLITES DATA

Sea surface temperature (SST) data from S-NPP VIIRS satellite has different spatial resolution with SST data from Himawari-8 satellite. In this study comparative analysis of potential fishing zones information from both satellites has been conducted. The analysis was conducted on three project areas (PA 7, PA 13, PA 19) as a representation Indonesian territorial waters. The data used were daily  for both satellites with a period  time from August 2016 to December 2016. The method used was Single Image Detection (SIED) to detect thermal fronts. Method of mass center point for determining potential fishing zones coordinate point from result thermal front detection. Furthermore, an analysis of overlapping was done to compare the coordinate point information from both satellites. Based on data analysis that had been done, the result showed that potential fishing zones coordinate points of Himawari-8 satellite was mostly far from potential fishing zones coordinate point of S-NPP VIIRS. The coordinate points whose positionswere close together or nearly same from both satellites was only about 20 %. Differences in potential fishing zones coordinate positions occur due to the effect of different spatial resolutions of both satellite data and the size of the front thermal events that had high variability. The ideal potential fishing zones coordinate points information was probably a combination of the potential fishing zones coordinate points of S-NPP VIIRS and Himawari-8 by making two adjacent coordinate points to be a single coordinate point. Field validation testing was required to prove the accuracy of the coordinate point

Viabilitas Dan Infektivitas Formulasi Cendawan Entomopatogen Lecanicillium Lecanii Sebagai Biopestisida Pengendalian Telur Kepik Coklat Riptortus Linearis

Lecanicillium lecanii fungi is an effective entomopathogenic fungus to control soybean pod sucking bug. The fungi is able to parasitize spore of pathogens that cause major diseases of soybean, such as rust, downy mildew, and powdery mildew. The study was aimed to determine the 12 formulations that can maintain spore viability and infectivity for 12 months. The formulations used talk, kaolin, sweet potato flour, cassava flour, rice flour, corn flour, soybean flour, mungbean flour, peanut flour, potato flour, molasses, peanut oil, and soybean oil based medium. Each medium was sterilized and mixed individually with conidia suspension of L. lecanii to form powder formulations that contained 107 conidia/ml. The spore viability and infectivity were tested after storing the formulations for twelve months. The result showed that viability and infectivity of spores in the formulation was lower with the longer period of storage. Viability of conidia in the formulation decreased to the lowest 20% after 12 months storage, especially that in peanut powder formulation. The spore viability in the cassava flour formulation was the highest (95%). Infectivity of the L. lecanii formulation using cassava flour to inhibit egg hatching of brown stink bug was 60% after 12 months storage. The viability and infectivity of L. lecanii spores in powder formulation was better than those in liquid formulations
