Abstract

A forklift is a lifting tool that functions to move goods from one place to another, with a short distance and a certain height, this heavy equipment is very useful because it can move very heavy goods in a vertical or horizontal direction. Problems that are often especially related to damage to unit components at PT.XXX, which are composed of the main part, namely the forklift engine. Damage to this section can result in downtime and delay in the production process which results in machine performance being less effective and efficient. Effectiveness in the production process requires the right strategy to keep the machine in operation by determining the optimal maintenance time interval using the criticality analysis method. After calculating with the criticality analysis method, it is found that the components of the hydraulic system and transmission are critical components. Furthermore, preventive replacement measures for hydraulic system components can be taken after 6800 hours of operation. The transmission component can also be done after operating for 900 hours or during an overhaul. While the inspection action for hydraulic system components is carried out after operating for 620.76 hours, the transmission component is carried out after operating for 540.39 hours. After checking and inspection, the avaibility value of the two components is above 95%, which means that the inspection can increase availability and prevent downtime in the unit and optimize the production process.

Abstract

PT. XYZ is a palm oil factory (PKS) producing crude palm oil (CPO). PT. XYZ has not implemented an effective engine maintenance system. The maintenance system that has been implemented is corrective maintenance, which is making repairs when there is damage. In addition, it is also assisted with planned maintenance that is scheduled every week to clean production machines. Therefore it is necessary to identify machine components that are susceptible to damage (critical components) and it is necessary to take special care measures for critical machine components by implementing a predective maintenance schedule (Prevention). Simulation techniques, often known as Monte Carlo simulation, estimate reliability using sampling random scenario. Failure mode effect analisys (FMEA) is defined as a process used to determine the actions that should be taken to ensure that each physical item or a system can run properly according to the function desired by the user then based on data processing, replacement of the roller binding drum binding drum , angle iron welding, chain transmission component replacement, drum stopper bearing replacement. Replacement of the drum stopper bolt, replacement of the chain transmission part is very loose and the replacement of the iron is carried out in corrective maintenance (replacement of components after damage occurs). And the results at the lowest value on the thresher engine component are in the Loose Transmission Chain component, the repair rate is 0.5 hours and the number is 0.999737189. Based on the results of the analysis of numbers (availability), the highest number is found in Broken Elbow Iron with a repair rate of 3 hours and the number 0.999605833

XYZ is a palm oil mill . Produce crude palm oil (CPO) PT. XYZ have not implemented the system machine maintenance effectively, maintenance system that has been implemented is corrective maintenance that is make improvements when there is a break down. Besides that it is also assisted with planned maintenance scheduled every week for cleaning production machines. The refore it is necessary to identify the engine components who are prone to breakage (critical component) and necessary to do action maintenance specifically against critical components engine by applying maintenance schedule prediktif ( prevention) simulation technique, often know as estimate reliability using a random sampling scenario failure mode and effects (FMEA) defined as a process used to deter mine action to be done to guarantee each item physical or system can go well according to the function performed by its usersthen basedon data processing, replacement, inspection of turn filter componentsone time per year with atime sixty minutes, thegear box is worn outonetime per year with a time of one hundred andtwenty minutes, leaking in the engine body as much asone a year during eighty minutes, thewire caught fire one time per year with time fifty minutes, cable having problems as much one time per year with time one hundred eighty minutes.

Abstract

Dashboard is a panel on the front of the car interior, here usually there are several facilities, such as instrumentation panels, drawers, radio / tape, and air conditioning. The dashboard also has many functions as a place for instrument panels and warning signal gauges and also has an audio system, ventilation air-conditioning head and many others. And here the researcher wants to know the strength on the car dashboard by using the tensile test method. Tensile testing is one such test. The method used in this research is a tensile test method using a UTM machine. Material testing machine with a length of 100 mm using ASTM E8. The results of the study have 5 specimens for the first specimen on the car dashboard having a tensile stress with a value of 33,95 Mpa strain with a value of 0,02 And the modulus of elasticity with a value of 1.697,5 Mpa the second specimen on the car dashboard has a tensile stress with a value of 35,98 Mpa strain with a value of 0,03 And the modulus of elasticity with a value of 1.199,33 Mpa The third specimen on the dashboard of the car has a tensile stress with a value of 43,55 Mpa strain with a value of 0,01 And the modulus of elasticity with a value of 4.345 Mpa the fourth specimen on the car dashboard has a tensile stress with a value of 33,95 Mpa strain with a value of 0,01 And the modulus of elasticity with a value of 3.395 Mpa the fifth specimen on the car dashboard has a tensile stress with a value of 42,77 Mpa strain with a value of 0,02 and modulus of elasticity with a value of 2.138,5 Mpa

Abstract

This design is based on the results of observations and literature studies, precisely for fish farming feed. Fish feed is always there, but has a relatively expensive price. Especially as a fish farmer, must have alternatives to develop his business. Because there is no use of a floating pellet molding machine, the machine was designed as a solution. Usually this machine is only used in pellet molding from fine bran and frementation materials that have been specifically designed to make animal feed. This design is carried out to make pellet printers from bran and calculate the production capacity. The design results use a 1450 rpm electric motor, 1:50 gear box, conveyor tank with a length of 220 mm, die with a size of 2 and 4 mm and a thickness of 8 mm, a cutting knife with a thickness of 1 mm, a length of 35 mm with a speed of 9 rpm and produces a capacity of 18 kg / hour.

Abstract

The use of biodiesel in boilers has great benefits because it can reduce exhaust emissions. The purpose of this study is to test the quality of diesel and biodiesel raw materials as fuel from boilers, analyze the concentration of polluting gases (NOx, CO2, SO2) from the combustion of biodiesel and diesel oil experimentally. The combustion system in boilers tends to be simpler than compression ignition as done in diesel engines. This research was conducted experimentally on a fire tube boiler, with a heat input rate of 60,000 kCal / hour and a pressure of 3 bar using biodiesel made from CPO (crude palm oil) as fuel. The mixture varies on 0, 5, 10, 15, 20 and 25% biodiesel in a mixture with biodiesel (B0, B5, B10, B15, B20 and B25). This research was conducted experimentally by testing exhaust gas emissions produced from exhaust gas chimneys which are expected to produce low exhaust emissions and are environmentally friendly. The results showed that the use of biodiesel reduces gas emissions by increasing the value of biodiesel in the mixture. The results showed that the lowest exhaust gas emission was around 4.142% (NOx); 12.50% (SO2) and 7.9% (CO2) are contained in a mixture of 25% biodiesel in fuel (B25).
