XYZ berdiri pada tahun 2015 merupakan perusahaan yang bergerak di bidang prasarana lalu lintas yang memiliki produk berupa Tiang RPPJ (Rambu Pendahulu Petunjuk Jurusan). Pada lini produksi sering terjadi bottleneck pada proses pengelasan lantai tiang terhadap tiang utama sehingga mengakibatkan ada beberapa work station yang mengalami idle time yang signifikan dalam setiap proses produksi yang dilakukan. Penyelesaian masalah bottleneck menggunakan line balancing dengan membandingkan tiga metode yaitu Largest Candidate Rule, Killbridge and Western Method, dan Ranked Positional Weights yang akan dibandingkan. Masing-masing dari ketiga metode tersebut akan menghasilkan line efficiency, balance delay, dan smoothness index. Metode yang memiliki line efficiency tertinggi akan dipilih sebagai metode yang direkomendasikan. Jika terdapat dua metode yang memiliki hasil line efficiency sama besarnya maka metode yang direkomendasikan dilihat dari nilai smoothness index yang paling mendekati 0 dari kedua metode tersebut. Hasil penelitian menunjukan metode Ranked Positional Weights sebagai metode rekomendasi dengan line efficiency 90,27%, balance delay 9,72%, dan smoothnes index sebesar 19,56936

For that reason many companies are currently attention to environmental issues. The concern not only in the production process but in the overall activities. This research use the Green Supply Chain Operation Reference (Green SCOR) method to evaluating the green supply chain performance in steel company. Key Performance Indicator divided into five categories i.e. plan, source, make, deliver and return. The result of Monitoring System Performance Indicators is 67.73 (average category). From SNORM value in Traffic Light System, the water used is the lowest. And the value is 38. This shows a lack of performance value and needs improvement.

Goal of queue model is decreased two total cost, direct cost and in-direct cost. Direct cost come out from facility services and in-direct cost to come out from waiting time. Simulation methods be needed before we running model for existing, because can be decrease of cost. Summary from this research is The Gunung Anyar is be obtained λ = 79,0 s/people, μ = 38.2 s /people, Lq=152 people and utilization 100%. The KUD Rungkut Branch is be obtained λ = 36 s/ people, and the from locket 1, μ 1= 39.8 s/ people, Lq=324 people, and locket 2, μ 2= 47 s/ people, Lq= 118 people, utilization 52%. And the last Branch is Barata Jaya is λ =29 s/people, from locket 1 , μ 1 = 40.25 s/people, Lq=76 people; μ 2 = 39 s/people, Lq =84 people; μ 3 = 38 s/ people, Lq = 93 people, and utilization 63%. For KUD Rungkut Branch no more increment employee, but skills must be increase and the Barata Jaya Branch skills employee is not average so empl...

Research paper thumbnail of Line Balancing Techniques for Efficiency Improvement in Construction Steel Company

XYZ company is a company engaged in steel construction. This company produces steel construction ... more XYZ company is a company engaged in steel construction. This company produces steel construction with several classifications, namely Building Construction (structure) and Mining Construction (Conveyor and Tank). This problem is found in the production process area where the efficiency of the company is not optimal because of the bottleneck between workstations. To increase efficiency and reduce bottlenecks, companies use the Largest Candidate Rule (LCR); Killbridge and the Western Method (KWM); and the Ranked Positional Weights (RPW) Method. After comparing the three methods, LCR has the best results. Production line efficiency is 92.2%, balance delay is 7.8%, and the smoothness index is 14.6 with 11 operators.

Integrasi yang baik diantara komponen reverse logistics (factory, recycled center, collection center, disposal center, distribution center), pemerintah sebagai regulator dan konsumen akan dapat meminimasi permasalahan lingkungan yang ada. Reverse Logistics (RL) merupakan salah satu metode untuk mengantisipasi permasalahan lingkungan, meningkatkan keuntungan perusahaan dan menurunkan jumlah produk yang kembali (return). Dari disain model RL pada industri elektronika konsumsi dilakukan tiga proses penilaian yaitu: framework untuk menilai tingkat implementasi RL, Total Reverse Logistics Cost (TRLC) dan House of Reverse Logistics (HRL). Pada pengujian framework dilakukan pada tiga industri elektronika konsumsi yaitu PT.PCB, PT.SA dan PT.GMEI. Hasil dari perhitungan menunjukkan Level Developed (Level 3) untuk PT. PCB dan Level Managed (Level 2) untuk...

X,Tbk area gudang secondary raw material es krim, peneliti melihat terdapat bottleneck pada proses pengiriman secondary raw material seperti wrapper, outter, kacang, dan stick dalam proses pengiriman ke ruang produksi. Sehingga membuat terkendalanya proses pengiriman secondary raw material tersebut. Variabel terbagi menjadi 2 macam yaitu variabel terikat dan variabel bebas. Untuk variabel terikat berupa waktu kedatangan material dan waktu pengiriman material. Untuk pengumpulan data terbagi menjadi 2 berupa data primer dan data sekunder. Data sekunder yaitu kegiatan pengiriman line material dan data kebutuhan macam-macam material. Pengolahan data dengan software Simul8 untuk rancangan model line pengiriman, Dari hasil proses running dan berdasarkan tabel rangkuman hasil simulasi diatas dapat diketahui bahwa rata-rata tingkat kegunaan (utilitas) untuk periode produksi bulan oktober 2013 dengan jumlah 2 line pengiriman secondary raw mat...
