Abstract

The national sugar production capability especially of the state owned sugar factory tends to decrease while demand increases.   To overcome the problem, government has issued the presidential Decree No. 5/2010 and declared a revitalization program of sugar industry as a priority development program. The Ministry of Industry has implemented the program by restructuring the sugar factorys machinery/equipments.  Since there are many of factories (51 units) and the budget is limited, the ministry should be selective as to which factories need to be restructered, and therefore the program shoud be supported by prior information about the machinery efficiency status of each factory. To provide those information,  this study applies the application of the Overall Equipment Effectiveness (OEE) method on 39 state owned sugar factories.  The results indicate that the everage rate of OEE for the 39 sugar factories for the year of 2010 to 2012 is 61.28% (best practice: 77.4%), while Availability, Performance, and Quality is 86.43%, 91.39%, and 77.02% respectively. The study also identifies 19 worst factories in efficiency, and therefore recommends those factories as priority to be restructured.

Abstract

A study on the conglomeratic sandstone and siltstone unit (Qoa) in the Mulyasejati Village (Kabupaten Karawang) and Conglomeratic and tuffaceous sandstone unit (Qav) of Pleistocene age in the Cilangkap Village (Kabupaten Purwakarta) has been carried out. The objectives of this paper are to reconstruct the mechanism of Depositional Period Intervals (DPI) of each lithologic unit. Sedimentological and stratigraphical analyses were carried out in the field based on seven vertical measured section of 1:50 scales. The thickness of the sections range from 1.20 to 7.70 m. Based on the correlation, both of lithostratigraphic units belong to into fluvial systems, and can be divided into four DPI (A to D). The sedimentary facies pattern of each DPI is controlled by the thrust structure, and are shown by stacking channels (FAS) 1 to 4. Whereas, the vertical composition of sediment is controlled by the fluctuation humidity related to climate change following Milankovitch cycles. Changes in the colour and composition of the sediments of the fluvial systems during the depositional processes of DPI A-D, can be interpereted as the result of climate changes. The climate circulations starting from nearly climatic optimum to climatic minimum or even dry.Keywords: facies, fluvial, climate, Interval of Deposition Periods
