Abstract

One main problem characterizes linear programming is to seek the maximum or minimum of a linearexpression when the variables of the problem are subject to restrictions in the form of certain linearequalities or inequalities. Problems of this kind are encountered when we have to exploit limitedresources in an optimal way. Project Cost Evaluation which play an important role in project are ofspecial significance in this respect. The real problem of Project Cost Evaluation analysis are tomanipulate cash flow problems of project into linear programming model or mathematical model.This method should be selected technically according the actual condition of the project. In designingand selecting the mathematical models, it is necessary to take into consideration the relationshipbetween the limited resources (money) and the optimal solution.

Abstract

Ventilation in ships is a process substitute dirty air in a hold of ship with fresh air from outside. If meansfor keep air in compartment always clean or fresh to make people comfort and to limit influence destructionpart of ship also rattenness of cargo that caused by too high dampness of the air.Ventilation system in ships differences two kind, that are natural ventilation system and mechanicalventilation system.Natural ventilation principles uses movement or flow of natural air, for example there are wind or air flowthat caused by symptom of air rising because temperature different. Where as on mechanical ventilationsystem the principles same with natural ventilation system, but air movement helped by ventilator oranother similar tools that rotation in the tube.

Abstract

The port of Tanjung Emas Semarang was located at the coast needed more clean water for shipping,industries and the communities. The production process of PLTU Indonesia Power produced waste wateras cooling water that caused thermal pollution. Considering the quality, quantity, and continuity of thatwaste water used as one of alternative source of clean water. It treated using by multistageflash recycleddistillation method. The purpose of this plant to fulfill clean water for shipping and port of Tanjung Emasarea with production capacity was 50 liters per seconds for duration planning about 15 years. The locationof this plant was next to PT. SRIBOGA with area 8000 m2, wherein the intake on the Canal of PLTUIndonesia Power. In order to fulfill the quality of water, this plant used oil separator and antiscalant aspretreatment. Production cost of distillation plant was Rp 13.647 per m3. This cost was too expensive so itrequired to be done crossed subsidy. The price of clean water was Rp 2000 /m3 for public, Rp 5500 per m3for industries and Rp 3000 per m3 for governmental office.
