Abstrak: Supply chain performance is an indicator of how well company runs its business process. Supply chain performance measurement is needed to control and to know company's performance position. This research aims to identify, calculate and formulate improvement strategy of cane sugar agro-industry supply chain in PT A. Supply chain performance was obtained by SCOR and fuzzy-AHP approach. Supply chain performance improvement strategy formulated by SWOT analysis and fuzzy AHP. The results of expert assessment for supply chain performance measurement matrix by the fuzzy AHP that three highest weights were processing cost (0.168), delivery accuracy (0.157) and perfect condition (0.119). Supply chain performance measurement results in PT A on the year 2013 showed the average performance of plantation was 61.78% and mill performance was 63.05%, while in 2014 the plantation average performance was 60.30% and mill performance was 56.80%. SWOT analysis on internal factors showed total value was 2.348 while 2.449 external factors. Through evaluation of internal and external factors, the company’s position known as Quadrant II (+0618;-0195). This research suggested to intensify research and development to maintain quality, yield and performance as the best strategy to improve supply chain performance.

Judul: Analisis efisiensi proses produksi untuk peningkatan kinerja industri gula tebu (Cane Sugar) (Studi kasus di PG. Jatiluhur Majalengka, Jawa Barat)
Abstrak: Sugar is one of the most important commodities in Indonesia. Most of sugar manufacturing in Indonesia was owned or sun by Indonesian government. Sugar consumption rate cannot be fulfilled by local sugar manufacturer, that's why importing sugar became an option. The insignificant rate of increasing of sugar production every year make import rate is keep increasing Efficiency in sugar production process is one thing that need some attention. This time, most of sugar factory that owned by government are decreasing in productivity. PG Jatitujuh is sugar processing factory that processing cane into white crystal sugar (SHS) and one of sugar factory in Java that still runs well. Efficiency in sugar production process can be analyzed by using PG Jatitujuh production data. Analysis result shows that efficiency in sugar production process can be rendered, by optimalised increasing of imbibitions water. The optimum value of imbibitions water is 25-30 percent of processed cane. The decline of pol value in the amount of 0,01 percent is equal with 1,729 ton or equal with Rp. 8.297.865,- recovery sugar £rom bagasse. The decline of HK value in the amount of 0,01 percent is equal with 0,273 ton or equal with Rp. 1.3 12.524,- recovery sugar from molasses.

Abstrak: The solution of Schrodinger equations with plasma Coulomb potential in spherical coordinat results solution wave function and energy plasma particle. Electron probability density at Debye length with thermal effect same as ion, which indicates plasma in neutral state. Electromagnetic waves perturbation of an electric field given to result wave function perturbation system. The probability density of plasma particle due to electromagnetic waves perturbation is the largest when an electromagnetic waves frequency 1.41 times the plasma frequency .
