Abstract

ABSTRAK PT Trimatra Utama Konsultan berfokus pada solusi dan layanan terhadap pekerjaan survey tower Base Transceiver Station (BTS) yang merupakan tower dari klien PT Trimatra. Pada beberapa hasil survey dari beberapa tower pada januaridesember 2021 ternyata PT Trimatra menemukan permasalahan seperti defect pada struktur tower yang tidak sesuai dengan standar waktu yang telah di tetapkan oleh perusahaan yaitu sebelum 5 bulan sesudah pembangunan ternyata sudah mengalami defect pada struktur tower. Dengan permasalahan tersebut maka penelitian ini bertujuan untuk mengetahui jenis defect yang tertinggi, mengidentifikas factor penyebab defect dan memberikan usulan perbaikan rencana pembangunan dengan metode DMAIC. Diketauhi ada 3 jenis defect berdasarkan pengolahan data. Berdasarkan hasil analisa dengan menggunakan diagram pareto defect kaki tower retak merupakan defect dominan dengan persentase sebesar 51,3%. sehingga usulan perbaikan di fokuskan pada defect pondasi kaki tower retak, faktor yang menyebakan defect tersebut yaitu ada 4 faktor yaitu manusia, mesin, material dan metode. Lalu usulan perbaikan yang dapat diberikan adalah melaukan training kepada pekerja, melakukan pengecekan kesehatan kepada pekerja, pemilihan material yang memiliki kualitas terbaik, melakukan pengecekan secara rutin pada mesin molen sebelum di gunakan dan servis secara rutin, kualitas beton yang di gunakan adalah dengan perbandingan 1Pc : 2Psr : 3 Split. Kata Kunci : DMAIC (Define, Measure, Analys, Improvement, Control), Kualitas, Defect Produk, Diagram Pareto. http://digilib.mercubuana.ac.id/ v ABSTRACT PT Trimatra Utama Consultant focuses on solutions and services for the survey tower Base Transceiver Station (BTS) In several survey from several towers in January-December 2021, it turned out that PT Trimatra found problems such as defects in the tower structure that did not comply with the time standard set by the company, namely before 5 months after construction, it turned out that there had been defects in the tower structure. With these problems, this study aims to determine the type defect , identify the factors causing the defect and provide suggestions for improvement of the development plan using the DMAIC method. It is known that there are 3 types of defects based on data processing. Based on the results of the analysis using the Pareto diagram, the fractured tower leg defect is the defect with a percentage of 51.3%. so that the proposed improvement is focused on defect of the cracked tower foot foundation, the factors that cause the defect are 4 factors, namely humans, machines, materials and methods. Then the proposed improvements that can be given are conducting training to workers, conducting health checks on workers, selecting materials that have the best quality, conducting regular checks on the molen machine before use and servicing regularly, the quality of the concrete used is with a ratio of 1Pc: 2Psr : 3 Splits. Keywords : DMAIC (Define, Measure, Analys, Improvement, Control)., Quality, Product Defect, Pareto Diagram.
