The company produces several automotive components in Karawang. For the production process using Fanuc machines on Line1, but the results of evaluating the performance of the engine Fanuc Line1 engine effectiveness is not optimal. It was alleged that due to the planning and maintenance of the management machinery was not good, so that the frequency of damage to the machine was still high, which gave the effect that the production was not achieved. For this reason, the effectiveness of the use of Fanuc line1 is done by using the Overall Equipment Effectiveness (OEE) method with the Six big losses calculation approach so that the level of efficiency can be known. The results showed that the magnitude of the OEE value on Fanuc line1 machines in April – August 2018 amounted to 78.82%, this value is still below the JIPM standard of 85%. The amount of Losses is influenced by reduced speed loss of 57.47% and breakdown loss of 22.79%.

The pipeline network in the petroleum industry is very susceptible to corrosion.  Corrosion problems can cause losses that are not small financially.  Corrosion that occurs in underground pipes can be in the form of external corrosion on the outer surface of the pipe caused by acid content in the air or in the soil or internal corrosion inside the pipe caused by petroleum content in the form of water, carbon dioxide (CO2) and hydrogen sulfide (H2S).  Corrosion causes the useful or service life of these pipes to be shorter than expected.  This study aims to measure the Remaining Service Life (RSL) of the petroleum distribution pipeline as an initial step of preventive action to avoid fatal consequences of corrosion problems.  In this study, ultrasonic testing was used as one of the Non Destructive Testing (NDT) methods to check the condition of the petroleum distribution pipe's wall.  In this study, it is found that the Remaining Service Life (RSL) of the pipeline under investigation is 25 years.

A B S T R A KMesin pendingin atau refrigator sangat dibutuhkan guna membuat makanan dan kebutuhan rumah tangga lainnya agar tetap segar dan awet dengan cara menukar atau membuang panas pada makanan tersebut. Tujuan dari penelitian ini yaitu merancang sebuah alat pemanas air dengan memanfaatkan panas dari kondensor mesin refrigator ½ PK sebagai keuntungan tabahan. Perancangan dimulai dengan identifikasi permasalahan, menghitung kebutuhan panas, menentukan dimensi dan juga komponen utama pemanas air. Berdasarkan hasil analisa dimana dimensi tube sebesar diameter 8 mm, tebal 2 mm dengan panjang sebesar 0,5 meter dan tangki berkapasitas 20 liter, didapatkan bahwa refrigator ½ PK dengan freon yang keluar sebesar 65˚C hanya mampu memanaskan air sebanyak 3 Kg dari temperatur 28˚ menjadi 60˚ dalam waktu 59 menit, dengan beban panas sebesar 130,74 Watt dan hasil yang dicapai dari CFD menunjukan panas yang masuk pada tube sebesar 65˚C akan berkurang setelah mencapai 1/3 dari panjang tube.
