    ANALISIS ANOMALI KANDUNGAN TOTAL SULFUR BATUBARA SEAM X78 FORMASI BALIKPAPAN DI DAERAH SEPARI KALIMANTAN TIMUR

    ABSTRACTCoal seam X78 at Balikpapan Formation, Kutai Basin, laterally has a totalsulfur content of anomalies, which in the north and south of the study area is quitehigh sulfur content than in the central part of the study area with an increasing trendto the south of the study area.Intent of this study was to determine the relationship of depositionalenvironment of coal and rock influences anomalies flanking the total sulfur content ofseam X78. The method of analysis used was the proximate analysis to determine theash content and calories, ash chemical analysis to determine the content of Na2O,petrographic analysis to determine the maceral composition, forms of sulfur analysisto determine the type of sulfur and SEM analysis to determine the type of pyrite, totest the effect of total content sulfur rocks flanking the total sulfur content of the coalseam X78, performed the statistical analysis.From the analysis of known petrographic maceral composition maceraldominated by herbaceous plant origin, with a tendency towards the north to thesouth of the study area, showed an increase in maceral composition of nativeherbaceous plants and inversely proportional to the maceral composition of plantorigin further to the south where the wood dwindle.Coal seam possible X78 deposited in lower delta plain environments with subenvironment limnic - marsh.Based on the statistical analysis of the influence of rock flanking, the totalsulfur content anomalies seam X78, rock flanking affect the total sulfur content of thecoal seam X78, especially on block 1 total sulfur coal seam X78 is influenced by thetotal sulfur content of the rocks flanking the top and the total sulfur content of therock flanking the bottom .
