In this study, a computational numerical modelling for corrosion simulation in reinforcing steel is developed. The corrosion simulation using Boundary element Method (BEM) and focusing for cylindrical reinforced concrete (RC). The main problem is high performance computer was required for the reinforced concrete corrosion simulation. Therefore, main purpose of this study is to reduce the needs of high-performance computer during the corrosion simulation. For the purpose, axisymmetric computational problem was integrated to the numerical BEM that considered able to reduce the computational effort. On the analysis process, the whole axial RC structures column was modeled by Laplace equation. The boundary condition for the corroded and non-corroded areas on the reinforcing steel (rebar) were represented by their established polarization curve. The Laplace equation was solved by BEM, thereby the potential on the structure can be analyzed. The simulation results show the similar potential distribution between BEM computational modelling by triangle element mesh and improvement BEM using axisymmetric element mesh problem. The simulation shows a significant differences, thereby the corrosion simulation using axisymmetric element mesh problem significantly reduces the computer effort in term of time-consuming and computer effort for the simulation. Thus, the improvement of the axisymmetric modelling for BEM becomes a powerful method for reducing the computational effort in term of cylindrical reinforcing steel corrosion simulation. Keywords— corrosion modelling, axisymmetric, BEM, cylindrical column, reinforced concrete

Noise standards on a machine are very important to consider before the machine is produced, because it can cause discomfort to the operator and damage hearing function. The noise standard has been set by OSHA, the maximum noise threshold value of 85 dB is considered safe for most workers when working 8 hours / day. The coconut milk production machine with a capacity of 10 liters per hour was carried out by measuring the noise level which aims to determine whether the machine meets the noise standard criteria. The test was carried out at three levels of motor rotation, namely 1000 rpm, 1500 rpm, 2000 rpm with a noise measuring distance of 0.5 meters from the component parts of the electric motor and centrifugal tube using a sound level meter. The results of measurements of noise levels on electric motors and centrifugal tubes of coconut milk production machines with a capacity of 10 liters per hour can be concluded that the noise level value of the production machine meets the noise standard level required by OSHA 1978, where the maximum production machine noise level is at 75 dB while that which is implied by OSHA 1978 maximum is at 85 dB. Keywords— OSHA standards, electric motor, centrifugal tube, noise test

Baja tahan karat AISI 304 secara umum digunakan pada mesin-mesin konstruksi terapan sederhana seperti poros propeler kapal nelayan, mesin penghancur es, pemeras tebu dan lainnya, dikarenakan ketahanan korosifnya yang baik, disisi lain kelemahan AISI 304 pada kondisi lapangan sering mengalami deformasi dan kepatahan dengan putaran yang relatif tinggi. Untuk mengatasi hal tersebut dapat dilakukan usaha menambah nilai kekerasan permukaan dengan melakukan pengujian Jominy Hardenability. Pengujian Jominy yang dilakukan pada spesimen uji dengan standar ASTM A255-02, dengan laju air pada nozzle 45 liter/menit, pada temperature 8500C dan holding time 15-20 menit. Hasil pengujian menunjukkan bahwa nilai awal kekerasan permukaan pada ujung quenching sisi A adalah 187 HB dan pada sisi B adalah 170 HB. Nilai kekerasan permukaan setelah di normalizing pada ujung quenching sisi A adalah 182 HB dan pada sisi B adalah 188 HB. Maka terjadi penurunan kekerasan pada sisi A sebesar 5 HB, dan terjadi peningkatan kekerasan pada sisi B sebesar 18 HB. Setelah di uji Jominy nilai kekerasan pada sisi A adalah 227 HB, dan pada sisi B adalah 223 HB. Pada pengujian jominy terjadi peningkatan kekerasan pada ujung sisi A sebesar 45 HB, dan peningkatan kekerasan pada sisi B sebesar 35 HB. Hasil penelitian ini dapat direkomendasikan bahwa AISI 304 sebelum digunakan sebaiknya dilakukan pengerasan permukaan sehingga sifat mekanik bahan menjadi lebih optimal.Keywords : Uji Jominy, AISI 304 , Normalizing, ASTM A255-02
