Abstract

This study aims to determine the quality and mechanical properties of carbon steel pipes for the production process at a good liquefied Liquified Natural Gas and after 10 years of use. As a temporary repair reference on damaged pipe. The step is to compare the results of testing the mechanical properties and microstructure of both types of pipes. The parameters used are chemical composition, hardness, tensile strength, and micro structure of both types of pipes. Test results on a good pipe have an average hardness value of 90 HV whereas in the damaged pipe the average hardness value of 85.9 HV decreased by 4.1 HV. The tensile test on a good pipe value of 60kg / mm2 (588 MPa), on a damaged tube of tensile strength of 56 kg / mm2 (549 MPa), decreased 4 kg / mm2 (39 MPa). Good pipe microstructure test results consist of ferrite and pearlite structures while in the damaged pipe consisting of pearlite phase. From the results of the study concluded that the pipeline after the use for 10 years experienced a decrease in mechanical properties, namely: hardness and tensile strength. This is the result of thinning of the corrosion pipe wall thickness.

Abstract

Leaf spring is one of the components contained in the rear suspension system and made from high carbon carbon steel. Nowadays, many people do leaf spring modifications, one of them is by the pressing process, but many of the vehicle owners modify it excessively and finally leaf springs broken. Therefore to know how the strength of leaf springs is done by testing the chemical composition test, metallographic test, hardness test and tensile test, the test is done in PT.IWWI located in tangerang area. The sample used to perform the test consisted of 4 samples, namely sample A, sample B, sample C and sample D, taken from each spring number 3 which has been modified as much as 2 cm and that has not been modified. From the four tests obtained results from testing the chemical composition of carbon content contained in sample C is highest with the value of carbon content contained 0.7719. From the hardness testing of sample which has the highest hardness value is sample C with hardness value 111.06 [kgf]. and from the sample tensile strength test which has the highest tensile strength value is sample B with a tensile strength value of 1408.75 [N / mm2].

Abstract

Gas Turbine Generator (GTG) 8 operates since January 2010. The problem that occurs from the gas turbine system is decreasing of electrical power. From the commissioning data, GTG 8 is capable of generating 120.2 megawatts of electrical power. In March 2017 GTG 8 was only able to generate electricity by 109.1 megawatts. There was a decrease of 9.23% of electric power capacity. Overview of thermal efficiency and heat loss needs to be done to find out improvement opportunities and recommendations. At commissioning period, thermal efficiency reaches 32.06% while from 2013 to 2017 the average thermal efficiency value reaches only 29.25%. From the data obtained rate of efficiency decreasing 2.81%. At commissioning, the resulting heat loss only reached 135.03 MW. The current operating conditions average heat loss reached 172.50 MW. There was a deviation of 37.47 MW or 21.7%. Based on calculations and data, one factor that can decrease of thermal efficiency and increase heat loss is the compression temperature. The increase in compression temperature is caused by the dust and impurities that enter into the compressor that precipitates on the compressor blades so that the compressed air temperature tends to increase. Dust and impurities can be reduced by the offline water wash method. This process can lower the compression temperature from 693.68 OF to 690.62 OF. A decline of 3.06 OF. This results in actual work of the compressor decreasing from 153.26 Btu / lb to 152.13 Btu / lb. Turbine thermal efficiency tends to increase from 29.02% to 29.43% or increase by 0.41%. After the offline water wash process, the generator generated power reaches 110.50 MW. Increases 4 MW or 3.62% compared to before the compressor is cleaned. The increase causes the system's heat loss to decrease by 5.2 MW or 2.96%.

Abstract

Pada masa globalisasi seperti saat ini, industri berlomba-lomba untuk dapat menjalankan produksinya dengan efisien. Semakin efisien suatu proses yang dijalankan maka semakin rendah pula cost yang akan dikeluarkan. Demikian pula yang terjadi pada Line Rear Axle Assy, dengan mempunyai efisiensi lintasan sebesar 88,28%, lini produksi ini mempunyai waktu menganggur, sehingga kapasitas produksi menjadi rendah dan mengakibatkan Loading vs Capacity (LVC) lini tersebut tinggi, yaitu menyentuh angka 126%. Dengan metode penyeimbangan lintasan (line balancing), kita coba untuk meningkatkan efisiensi lintasan yang nantinya berdampak pada peningkatan kapasitas produksi dan juga akan menurunkan LVC. Setelah dilakukan perbaikan, dengan kondisi lintasan yang semakin seimbang, efisiensi lintasan pun meningkat dari 88,41% menjadi 97,96%. Perubahan efisiensi ini, berimbas pada kapasitas produksi yang juga ikut bertambah sebesar 9,23%. Dengan naiknya kapasitas produksi sebesar 9,23%, berdampak pula pada penurunan LVC dari 126% (waktu kerja 3 shift + 4 Sabtu + 4Minggu), menjadi 119% (waktu kerja 3 shift + 4 Sabtu), kapasitas produksi meningkat 6 unit/jam, total keuntungan perusahaan bertambah sebesar Rp.9.179.160.000.-
