Abstract

An engine bleed trip is an indication that there is a failure in the engine bleed system in regulating the temperature and pressure of the bleed air. This can affect the work of other systems that rely on the output of the engine bleed system, one of which is the cabin pressure system. The aim of this research is to find out the percentage level of the need for main components in the engine bleed system to be replaced in handling engine bleed trip cases. This research is an ex post-facto comparative research with primary data collection methods sourced from aircraft maintenance databases and interviews. The research results showed that from a total of 52 bleed trip cases that occurred during 17 months, the percentage of main components that needed to be replaced were the 390F thermostat sensor (42.3%), precooler control valve (19.2%), pressure regulating shuttle valve (11 .5%), bleed air regulator (7.7%), and the rest are other components.

Abstract

Criminal acts in the community such as theft of motorized vehicles, bicycles and hit-and-run victims are increasingly widespread, in the last 1 year in Fanindo housing there have been four thefts of children's bicycles. Therefore, a security system is needed in the housing to prevent and monitor things that harm the community, namely in the form of CCTV. The methods carried out in the service include surveying the location to determine the strategic installation point with the local RT head, selecting the type of camera, determining the electrical path, determining the placement of the DVR (Digital Video Recorder), and software settings. This service activity received a very positive response from both the RT management and the local community and is expected to be able to reduce criminal acts such as theft and other criminal acts.
