Abstract

Motor diesel is growing rapidly now, and have a better performance, technology and construction machinery has undergone innovation - innovation that spectacular, fuel system, air intake systems and other systems, which can support the engine performance is also experiencing a very recent innovation. Diesel engines are usually called compression ignition engine (compression ignition engines), how ignition fuel is done by spraying fuel into the air that has been pressurized and high temperature. Currently diesel engine with a small total volume produce big power, is none other than the already wide use of the turbo charger to add the intake air pressure and increase the effective pressure, increased air temperature in the cylinder so the engine power increased by approximately 25% compared to engines without turbo chargers . Turbo Charger driven by exhaust gases from combustion, where the turbo charger has two main components of the turbine wheel, made of heat-resistant cast metal and compressor wheels, made of aluminum alloy in rollers and then done.

Abstract

In this globalization, companies are have to increase productivity in order to produce maximum output. In this case, especially system productivity company. Smoothness system or production process is supported by many aspects, one of which is the aspect of reliability of existing machinery or equipment in the production system.In palm oil mills, there are two processing stations and processing of palm fruit processing palm kernel. Palm kernel oil processing systems, among others, Pressing, Nut fiber, Depricarper, Polishing drum, cyclone Nut, Nut hoper, Ripple mill, LTDS 1 & 2, Claybath. To increase the productivity of these systems need to be an appropriate activity treatment on the machine or equipment, in an effort to increase conduction reliability of the equipment in the system kernel oil processing. For it is necessary for treatment planning method RCM (Reliability Centered Maintenance) using qualitative analysis where the RCM method can determine the identification of critical equipment and components, optimum care, treatment and consequences of activity intervals failures in machinery or equipment or core processing system palm on palm oil mills company.

Abstract

Rokan Hulu regency government is very concerned with people's needs for clean water for the most budget Rokan Hulu regency government owned companies to build infrastructure through water distribution unit called the Badan Pengelolaan Air Bersih (BPAB), one unit of water distribution net is BPAB Pematang Barangan-Pasir Putih. A water distribution unit is a group function, system, sub system, and item components are complete and mutual support for the smooth operation and water distribution.In water distribution unit BPAB Pematang Barangan for water distribution system using a centrifugal pump, with sub pump system with a single puff volut brands Ebara PUMP. To reduce the downtime of time it needs to be done to improve the availability of treatment / usability (availability) in the system function. In order to serve the function of the system can then use Reliability Centered Maitenance(RCM) method to be implemented by means of qualitative analysis on the component item that can be analyzed in detail the use of Failure Mode Effect Analisys (FMEA), Logic Tree ANALISYS, and Maintenance Task.
