"Applied supply side Management of electric Energy in Supply side. This is prior in order tooptimalize of using Hydro generation so it could operation as maximal as possible in the peak of systemloading. In this WG] eficiency of using minimum fuel as expected can be occur in Operation theThermal Generation.In order to have an optimum .system, in Electric Power System that consist of unit Hydro Generationand other Thermal Generation such as PLTU1 PLTP, PLTGDI PLTG. A loading regulation is necessaryto build in an electrical power generation, in order to have an optimum operation for electric powersystem, in which minimum fuel cost in operation electric energy need all. It is important to do because theelectrical power generation serves electric power loads, that always change by the time, and also resultfuel-cost per unit time in rupiahs pers hours, changes by the time.The cost of Electrical Power System operation is set as the goal to be minimized and the junction ofoperation cost will be change. Gradient Method will be used in order to solve this hind of matters. Theoptimum of generation regulation in this paper was restricted as generation regulation of real powerwhenever the optimum generation using this gradient Method is more profitable then using merit ordermethod technically and economically.In this case Computer program will be Applied using computer simulation in which Borland Delphirelease 7.0 as computer language programming, in order to to find an optimization of operation systemhydro-thermis power generation. As the result of Computer simulation program, is picture, table or chartthat would be easier to be understood."

"Penelitian ini bertujuan untuk mengidentifikasi efisiensi relatif antara kapal PT.PELNI dan faktor-faktor yang menyebabkan inefisiensi. Objek penelitian adalah 21 kapal pada periode 2009-2012. Variabel input yang digunakan dalam penelitian ini adalah dana untuk subsidi PSO, dan kapasitas kursi kelas ekonomi. Variabel output adalah jumlah penumpang kelas ekonomi, jumlah voyage, dan jumlah hari operasi. Penelitian ini menerapkan model Data Envelopment Analysis ( DEA ). Hasil penelitian: hanya ada 4 kapal yang konsisten relatif efisien pada periode 2009-2012. Penyebab utama dari inefisiensi kapal adalah jarak rute terlalu jauh, dan terlalu banyak kursi di kelas ekonomi. Dengan demikian, disarankan untuk membuat beberapa perbaikan dalam operasional kapal, terutama untuk memperpendek rute dan mengurangi jumlah kursi di kelas ekonomi.

This research is aimed to identify the relative efficiency among of PT. PELNI's ships and the factors that cause the inefficiency. The object of study are 21 ships at period 2009-2012. The input variables used in the study are fund for subsidy PSO, and seat capacity of economy class. The output variables are number of economy class passengers, number of voyages, and number of operating days. The study applied the model of Data Envelopment Analysis (DEA).

The research result: there are only 4 ships that consistently relatively efficient at period 2009-2012. The main cause of a ship inefficiency were the distance route is too far, and too many seat in economy class. Thus, it's suggested to make some improvement in operating of ships, especially to shorten the length of routes and to decrease the seat in economy class."
