PT. Pipa Mas Putih plant Batam merupakan perusahaan produksi screen dan OCTG pipes . Perusahaan ini menyokong kebutuhan pipa untuk perusahaan oil & gas . Di dalam proses produksi Tubing 3 ½ “93.30 PFF, J-55, EU, 8-RD, R-2 sering mengalami kemunduran lead time akibat kurang optimalnya produktivitas produksi dan menyebabkan terjadinya idle time yang teridentifikasi di lapangan. Penelitian dilakukan untuk mengetahui nilai selisih waktu total aktivitas aktual dan usulan setelah minimasi di dalam proses produksi produk OCTG dan mengidentifikasi pemborosan yang terjadi di PT. Pipa Mas Putih plant Batam. Hasil yang didapat: Banyaknya aktivitas produksi sebesar 38 aktvitas. Besar total waktu aktual sebesar 143,11 menit dan total waktu usulan sebesar 124,44 menit. Terjadi penurunan total waktu sebesar 18,67 menit. Pemborosan yang teridentifikasi mempunyai ranking tertinggi yaitu waiting, unnecessary motion, dan inappropriate processing .

The standard of efficient or not for a power plant can be seen from the value of plant heat rate. Plant heat rate is amount of energy required to generate one kWh electricity. The smallest of that is the best power plant . In general, the value of plant heat rate has increased than commisioning test after the power plant operated continously . The method used in the calculation of the steam power plant is energy balance method. Energy balance calculation method used by the standard of the American Society of Engineers Mechanichal Performance Test Code (ASME PTC). The value of plant heat rate is influenced by the value of turbine heat rate and boiler efficiency from steam power plant . Turbine heat rate is the required energy turbines obtained from heat transfer process to generate one kWh electricity, while boiler efficiency is an indicator from boiler performance of steam power plant by comparing the outputs and inputs. After calculation of plant heat rate at actual condition, the value of plant heat rate has increased than commisioning. The increrase of plant heat rate value is due to more losses which result degradation performance on the main components of the unis, such as : turbine, boiler, air heater and condenser. Therefore necessary corrective maintenance when first year inspection, so that the steam power plant can be re-optimal performance as at commisioning test.","PeriodicalId":441070,"journal":{"name":"Bina Teknika","volume":"2990 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127458384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this case the components studied are two type brake of aircraft the first one is brake assembly and the second one is brake Goodrich which installed on B737-800 aircraft NG. Based on historical data, in last 3 years PT ABC have a number of component shortage that continues to grow, in last year PT ABC had 12 unit shortage component for brake assembly and 13 unit shortage component for brake goodrich. It is gave the negative impact for company and also customer PT ABC. To overcome these problems need to be analyzed how to determine the accuracy the number of brake requests that will removal in future periods which resulting the accuracy of the flight time (dispatch reliability/delay time). The proccess in this reserach first determine the life time of brake, determine the quantity of removal brake, schedule of removal brake, account the forecast of requirement brake in next years and determine the planning of material requirement for maintenance proccess.
