Abstract

Problems on the construction project going on for many things, but the cause that often arises is the difference in the implementation of the planning of the field, causing a large increase in funding costs. Their main work items that are not entered into the budget plan, and there are differences of specifications in the plans designed by the consultant is one of the problems that occur. This research was conducted by two methods, namely quantitative data collection Budget Plan in the form of data, and the data volume deviation value-added jobs. Then do the data collecting qualitative data collection questionnaire with interview preventive and corrective actions to address and prevent these problems happening in future hari.Hasil study showed an increase in the cost of Rp.444.094.874 up 18% of the value of the contract so that the required solution / settlement on these cost increases. Obtained results of the questionnaire in the form of preventive measures such as: the process of selecting a consultant planner more selective, rigorous monitoring plan when making volume measurements in the field, and double-check the results of the planning. Corrective actions include: held CCO (Contract Change Order), Addendum, plus work less, and hospitalization for selectively on the added job priority

Abstract

In testing the water turbine installation should be able to test various types of water turbines and their characteristics. Known models such as the type of turbine, turbine pelton, francis, propeller / kaplan, and cross flow. pelton turbine is a turbine that has the characteristics of high head and a small discharge, whereas francis turbine for medium and discharge head being, as well as a turbine propeller / kaplan for low head dann large discharge. The test installation shall be able to accommodate the needs of characteristics (needs) of each turbine. Besides the problems of installation testing is also required measuring tools to measure / determine the magnitude of the parameter-parmeter time of testing, such as the flow of water entering the turbine, a large head of the turbine, the greater the power of the turbine, and the amount of rotation of the turbine when pengujian.Semua case must be thought out and designed to meet the requirements and testing purposes so that the results meet the desired accuracy.

Abstract

PLTGU designed for continuous running, but because of the condition of the network then UP Semarang is conditioned only operate during peak hours or when required by the Dispatcher because other units are holding maintenance or because of something that can not operate. This condition makes the gas turbine units at UP.Semarang often operate with a pattern start / stop, so that the equipment plays an important role in the process of start / stop required for work excellence. The method used to analyze the root cause failure disorders to Ignite Gas Turbine is the method of Root Cause Failure Analysis (RCFA). Based on the results of analysis by method RCFA, disruptions caused by failure to Ignite Liquid Fuel Nozzle Check Valve Failure to obtain Task that is in addition to the regular maintenance schedule after GTG operated by MFO also implement new PM replacement check valve for no.1 to 14 every 6 months , manufacture PM Visual check every 1 week and the addition of a new Prime Minister for a replacement check valve No. 4,5,10,11,13 and 14 every 3 months because often damaged.

Abstract

Power Plant is a type of thermal power plant that is widely used, because of its fuel efficiency is good and easily obtained thus producing electrical energy economically.One Supporting Components Boiler ie Furnace, Steam Drum, Superheater, Water Heater, economizer, Safety Valve, Sootblower. Sootblower a boiler auxiliary equipment which serves to clean the dirt produced from the combustion process that is attached to the tube wall pipes, superheater, reheater, economizer, and water heater. The goal is to keep the heat transfer takes place properly and effectively. Long Retractable type Sootblower placed in superheater, Reheat, and economizer. This type is on stand-by condition is outside, and when the work will go spinning and turning it back out. if on the flue gas temperature is still very high, causing Sootblower bent by heat if it is not pulled out.
