Abstract

Physical activity related to work activities on production operators is one of the jobs that needs attention. Operator activity on CV. Primavera, which is engaged in garments, especially in the fabric cutting Laser. section, is a fabric cutting process that uses high-power laser technology that is emitted from a generator on the workpiece, the cutting movement is controlled through a computer so that the possibility of slipping is small. During the cutting laser process, workers stand in front of the cutting laser machine and bend over while setting the fabric size according to the basket. These complaints arise due to non-ergonomic work postures causing pain in some parts of the body felt by workers. The purpose of this study was to determine the level of risk and the percentage of complaints felt during cutting laser. The methods used are Rapid Entire Body Assessment (REBA) and Nordic Body Map (NBM), based on the REBA method the work risks faced by workers in cutting laser cloth with a high level of scores in the range of 8-10, high category of action so it needs to be done immediately improvement of work posture. The Nordic Body Map shows the first body segment on the back with a score of 9, the second body segment on the right shoulder with a score of 8, the third body segment on the waist with a score of 8, the fourth body segment on the buttocks with a score of 8, and the fifth body segment on the legs. right with a score of 8, due to a bent work posture during the cutting laser process and fabric size settings as well as age and length of work factors that also affect the questionnaire.

Abstract

The activities of gas well exploitation have some problems. One of the problems is the amount of liquid (water) in the tubing column which obstructing the gas production. One of the ways to overcome the problem is to offload activity. One of the important equipment during offload activities is the offloading pump. An offloading pump is used to transfer liquid (water) from the well that has been collected in a vessel to the trunkline. This study aims to see the changes in the performance of the offloading pump between the initial conditions according to the manufacturer's specifications and the current condition after being used for ± 9 years. The type of pump being tested is a multi-stage centrifugal pump model 20 WUC-2R-19. The performance testing of offload pump is done by varying the discharge valve opening by 25%, 50%, 75%, and 100%. After that, compare the actual pump performance with the corrected data using the affinity law. The test performed during the offload process occur, and the fluid characteristics assume to be constant. The results showed that there was a decrease in performance between the initial operating conditions in 2011 with the actual conditions in 2020. The actual capacity of the pump decreased from 24 m3/h to be 23.45 m3/h. The efficiency of the offload pump decreased from the initial condition of 80% to 7.71%. The decrease in efficiency for 9 years is 2.29% or 0.25% per year.

Abstract

Bagasse fiber is an organic waste that is produced in many sugarcane processing factories in Indonesia. This fiber is also easy to obtain, cheap, does not endanger health and can also be degraded naturally. This research aims to determine the impact strength of the bagasse fiber treated with alkaline. The variables of this study are the immersion time of 1 hour, 2 hours, and 3 hours. The fiber used is sugarcane fiber and the volume fraction ratio of resin and catalyst 65% (2% catalyst) and 35% sugarcane fiber. Impact test is carried out according to the impact testing standard ASTM D 5942-96, by using the Charpy method. The result shows that among the three specimens tested, 1 hour immersed specimen has the greatest energy absorption with impact value of 0.5374 Joules/mm2. The longer the immersion time of bagasse fibers in the alkaline solution, the less energy absorbed. It also shows that the resin mixed with alkaline treated fibers has higher impact value than pure resin.

Abstract

A micro-hydropower plant is a small-scale power plant that uses water as its propulsion and the prime mover is a turbine. This generating system is very appropriate to be used in rural areas because this system is easy to manufacture, produces a large amount of electrical power, and is relatively inexpensive to manufacture. Based on the above, it is necessary to design a turbine that supports this generating system, including the Cross-Flow Turbine. To design a water turbine so that there are no errors in the design (such as the cost of making it), then a design is carried out. A cross-flow turbine design is designed with a flow rate (Q) = 1.2 m3/s, head (H) = 17 m with an efficiency of 0.75. The main technical specifications from the results of the turbine design are runner diameter (D) = 510 mm, turbine shaft rotation 471 rpm with a specific speed of 61.33 rpm, water power of 200,124 kW, and producing electric power of 100.86kW.

Abstract

The purpose of this study is to plan effective preventive maintenance activities so as to ensure the reliability of the system, so that it can operate without experiencing component damage components that cause system failure. The working system of the part number 541674-4 Ram Air Actuator of The Boeing 737 NG aircraft is often damaged, resulting in failure of the operational system, the cause of operational system failure is damage to the Wear and Bearing Damage component, Housing assembly, Bearing Damge problem, Wear Damage, Electrical Problem Stuck. These problems encourage research to overcome the damage and failure on the Ram Air Actuator system of the Boeing 737 NG. The study was carried out using qualitative analysis and quantitative analysis, qualitative analysis was carried out using the FMEA (failure mode effect analysis) method to identify and identify the cause of failure in the Ram Air Actuator system, quantitative analysis was carried out by calculating reliability using the Weibull distribution so that the life time limit was known. Critical part or Ram Air Actuator component. Based on the results of the reliability analysis, the operational time limit value is obtained, where the system will experience a critical period when it reaches operational time, namely Mechanical system = 1680 hours with a reliability value of 72%, Electrical system = 3401 hours with a reliability value of 72%, Pneumatic system = 3201 hours with a value of reliability 70%. After knowing the critical life time limit, preventive maintenance plans will be carried out on the parts and components that cause failure so that the Ram Air Actuator system failure of the Boeing 737 NG aircraft will not occur.
