Abstract

The purpose of this study is to identify the type of defects that occur, identify the causative factors of disability using SPC and FMEA methods to improve the competitiveness of network companies in PT. Xyz. From the results of the control map there is 1 point above the UCL limit that occurred in the 6th month. Furthermore, analysis with pareto diagram, which is known to be the most dominant defect there are 3 or 30% piece is not up to standard, 27% folds are not aligned, 23% sealing results are not perfect. From the highest percentage of analysis with fish bone diagrams, there are several factors that cause differences, namely human factors are less thorough, machines lack maintenance, methods are not up to standard, hygiene environment is poorly maintained and raw materials are not good. Furthermore, the analysis using FMEA to determine the priority scale obtained that the priority scale based on the RPN table including the sealing result was difficult to open with a total of RPN 338.8, the folds were not aligned with the total RPN of 212 and the pieces were not symmetrical with a total of RPN 106.5. Based on rpn table, proposed repair using 5W+1H obtained by proposed daily briefaing, scheduled machine checking, checking before materials are used, ensuring the settings on the machine according to standards.

Abstract

PT Jaya Inti Teklindo adalah perusahaan penyedia manpower, service and supply dibidang kontruksi. Studi kasus pada penelitian ini yaitu proyek kontruksi penggantian kompresor lama dengan yang baru. Penelitian ini bertujuan untuk menentukan kegiatan apa saja yang termasuk jalur kritis, melakukan perbandingan waktu dan biaya tenagaikerja akibat penambahanijamikerjaidan menentukan waktuisertaibiaya yang optimal untuk menyelesaikan proyek tersebut. Tahapan penelitian ini adalah pencarian kegiatan jalur kritis menggunakan program Microsoft Project, melakukan analisis percepatan durasi dan biaya tenaga kerja pada jalur kritis dengan variabel penambahanijamikerjaimenggunakan pendekatan TimeiCostiTradeiOff. Berdasarkan hasil analisisidan perhitungan, biayaitenaga kerja normal denganidurasi 70 hari yaitu sebesar Rp 332.119.200. Kemudian dilakukan percepatan sehingga menghasilkan waktu optimal penambahan 3 jam kerja, dengan durasi menjadi 59 hari dan biaya sebesar Rp 413.932.210 dengan menghemat waktu 11 hari dan selisih biaya Rp 81.813.110 dari biaya normal.
