Abstract. PT Mandiri Sejahtera Sentra (PT MSS) is a private mining company that extracts andesite rock, located in Sukamulya Village, Purwakarta Regency, West Java. The area covers 41. 19 Ha, and the aimed for production target of 470 tonnes per hour using jaw crusher equipment. However, it has not met this target, partly due to suboptimal close side setting (CSS) crusher. To address this, experimented with three variations CSS find optimal size meets goals without hindering cone crusher’s...

This paper presents a statistical interpretation of the chest radiograph for detection pulmonary tuberculosis (PTB). Each region interest was represented by vector wavelet texture measures which is then multiplied orthogonal matrix Q. The first two elements transformed vectors were shown to have bivariate normal distribution. Misclassification probabilities estimated using probability ellipsoids and discriminant functions. most important result this study recommends constructing function...

The conventional chest radiograph remains a widely tool in the diagnosis of lung diseases even to present day. Current methods or algorithms for disease detection focus on discrimination between normal images and with signs involving radiograph. This paper proposed novel algorithm solve difficult problem discriminating two similar diseases, pulmonary tuberculosis (PTB) lobar pneumonia (PNEU) using phase congruency. congruency PC(x) parameter estimation was studied obtain best PC(x)-values...

This study attempted to discriminate three types of lung disease pair-wise, namely lobar pneumonia (PNEU), pulmonary tuberculosis (PTB) and cancer (LC) using chest radiograph. A modified principal component method applied wavelet texture measures yielded feature vectors for the pair-wise statistical discrimination procedure. The combination mean energy maximum value gave good pairwise rate classification PNEU-PTB, PNEU-LC PTB-LC. result if this is very promising further work are needed...

Abstract. Natural disasters caused by geological aspects are difficult to predict when and where the disaster will occur because many factors can trigger a disaster. In West Java Province there have been around 64 incidents of landslides that harm humans. The Cimenyan sub-district is dominated topography Slope / Ridge area land use Forest Area with an altitude 946 meters above sea level. district, cover changes from green open spaces built impact on slope stability. Changes in conservation...

A novel procedure using phase congruency is proposed for discriminating some lung disease chest radiograph. Phase provides information about transitions between adjacent pixels. Abrupt changes of values pixels may suggest a possible boundary or another feature that be used discrimination. This property have potential deciding present and absent where the regions infection on images no obvious shape, size, configuration. Five texture measures calculated from Gabor were shown to normally...

A novel procedure to detect Interstitial Lung Disease (ILD) with High Resolution Computed Tomography (HRCT) images is proposed. Seven texture measures from a selected slice of HRCT lung image fifteen ILD cases, non-ILD cases and healthy individuals were obtained their pairwise correlation calculated. Two groups measure standard clustering then used create discrimination using simple linear regression. The Contrast Standard Deviation Energy (STDE) gave the highest detection rate.

Abstract. PT X is a mining company with open pit methods for andesite rocks. The implementation of inseparable from the problem inclusion water rainfall and groundwater seepage into area (pit). This can lead to disruption activities if not handled properly. In this case cope incoming at Pit in requires some study. It deals large number pumps needed tackle each day.The purpose research overcome potential entering Pit, by making diversion channels that already inside sump pumping system.The...

Abstract. Limestone is an excavated material that can be used as a raw for cement. In the manufacture of cement there are three materials, namely limestone main material, then corrective iron sand and quartz additive gypsum. The compound CaO compound. formation limestone, value content has variations due to differences in facies process, so distribution not necessarily homogeneous. With requirement which 47%, it necessary have model describe geometry sediment levels at research site....

Abstract. PT Tambang Semen Sukabumi (TSS) is a subsidiary of the Thailand Cement Group Siam (SCG). engaged in mining limestone and clay which are intended as main base materials for cement production supplied to Jawa. TSS has target fragmentation size 75% sizes ≤ 40 cm adjusted crusher opening. This needs be achieved order reduce additional process reducing boulder size. research aims know results from actual geometry design proposed blasting so that blast can well optimal amount explosives...

Abstract. In the mining industry, rocks are often found to be relatively hard and break up these rocks, a blasting process is needed. There several things that must considered in determining success of activity, including fragmentation rock resulting from blasting, because if too large (boulder), then secondary or will carried out reduce chunks form appropriate size. with subsequent work, causes additional costs, therefore accordance planning target avoid cost. this research, comparative...

Abstract. Excavation, loading and transportation activities are one of the that incur relatively large mining operational costs. There a number factors affect fuel consumption, particularly for mechanical equipment, including field conditions, equipment characteristics, road geometry. The goal this study on impact geometry consumption is to improve efficiency machinery used digging. In actual there several segments with grade conditions do not comply standard operating procedures based...
