Abstract

This study describes the analytical calculation of cold storage for preservation planning of beef in PT. Kepurun Pawana Indonesia (PT. KPI). Planning this cold storage will be addressed to the PT. KPI in Yogyakarta that one of his business is cattle farm. Because cattle results from this farm will be sold in the form of fresh beef. Therefore, these companies require cold storage for the storage of beef. Cold storage is intended to keep the quality of beef stays fresh, quality is maintained and not easily damaged or rotten. Cold storage planning begins by calculating the heat load of the product itself, followed by the calculation of the human load, load infiltration, load lighting and lighting loads. After that we can survey the price of machines such as evaporators, condensers, compressors and other equipment from the calculation that writers get. By designing the cold storage, is expected to help and solve the problem of PT. KPI itself in preserving beef before sale to consumers. Meat sales volume instability problems caused by market conditions can be overcome.

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.
