Abstract

Penjadwalan sangat memengaruhi jumlah waktu yang tersedia untuk menyelesaikan proyek di PT DBUS, ini dilakukan untuk mencapai hasil terbaik dengan mempertimbangkan keterbatasan yang ada. PT DBUS sering mengalami masalah dengan waktu penyelesaian proyek yang tidak tepat waktu, masalah ini dapat mengurangi kepercayaan konsumen. Tujuan dari penelitian ini adalah untuk menganalisis metode penjadwalan mana yang lebih efektif antara Critical Path Method (CPM) dengan Precedence Diagram Method (PDM) dibandingkan dengan kondisi saat ini. Data yang digunakan dalam penelitian ini berasal dari data sekunder yang dikumpulkan dari kontraktor pelaksana dalam bentuk time schedule rencana. Dalam membandingkan metode PDM dan CPM terdapat beberapa perbandingan antara lain, CPM dengan satu konstrain kegiatan sedangkan PDM memiliki empat konstrain kegiatan, perbedaan dalam lintasan kritis yang dihasilkan yaitu CPM dengan 21 lintasan kritis dan PDM dengan 19 lintasan kritis dengan durasi total pekerjaan proyek untuk CPM dengan 122 hari dan PDM selesai dalam 80 hari. Berdasarkan penjadwalan yang telah dilakukan metode PDM lebih efektif karena menjadwalkan proyek dengan durasi lebih singkat sehingga proyek dapat selesai lebih hemat waktu, hal ini pun mampu mengurangi terjadinya keterlambatan dikarenakan lebih sedikitnya lintasan kritis.

Abstract

Perjalanan bisnis dalam industri manufaktur membutuhkan kualitas produk yang menjadi faktor utama keberhasilan perusahaan. Produk yang berkualitas tinggi akan meningkatkan kepuasan pelanggan, loyalitas terhadap merek, dan pada akhirnya meningkatkan keuntungan perusahaan. Salah satu area yang sering menghadapi tantangan kualitas adalah line injection, di mana masalah seperti produk cacat, variasi dalam proses, dan waktu henti mesin bisa terjadi. Masalah-masalah ini dapat menimbulkan kerugian finansial yang signifikan bagi perusahaan. Penelitian ini bertujuan untuk menganalisis penerapan metode Six Sigma dalam pengendalian kualitas di line injection. Metode Six Sigma berfokus pada peningkatan kualitas produk atau layanan dengan mengurangi cacat atau kesalahan hingga mendekati nol. Penelitian ini menggunakan data dari PT ABC yang berlokasi di kawasan industri MM2100 yang diperoleh melalui observasi dan wawancara langsung. Hasil analisis menunjukkan bahwa berdasarkan data dari Februari hingga Juli 2024, di PT ABC ditemukan berbagai cacat injeksi, yaitu flash sebesar 1,15%, sink marks sebesar 6,22%, weld lines sebesar 37,12%, dan voids sebesar 55,49%. Cacat-cacat ini menyebabkan produk akhir tidak sesuai dengan spesifikasi yang diinginkan. Dalam tahap analisis, diketahui bahwa voids dan weld lines adalah dua jenis cacat yang paling dominan dalam proses produksi. Oleh karena itu, langkah perbaikan harus difokuskan pada dua jenis cacat ini, karena keduanya menyumbang sebagian besar dari total cacat yang terjadi. Perbaikan dapat dilakukan melalui pelatihan dan pengawasan operator, pengawasan material, serta pengaturan mesin.
