Line balancing adalah suatu usaha mengatur lintasan produksi dengan tujuan merencanakan keseimbangan lintasan stasiun kerja (work station) pada tingkat shop floor, guna memperoleh tingkat efisiensi kerja yang tinggi. Proses pembuatan T-Shirt di PT. Caladi Lima Sembilan (C-59) memiliki proses operasi yang tidak seimbang, sehingga terjadi penumpukan barang setengah jadi pada suatu stasiun kerja dan adanya waktu menganggur (idle time) pada suatu proses operasi karena adanya antrian barang setengah jadi pada suatu mesin (bottle neck). Metode Line Balancing yang digunakan adalah metode Hegelson-Birnie yang didasarkan pada prioritas bobot posisi setiap operasi/elemen kerja dan metode Killbridge-Wester yang didasarkan pada pembagian wilayah. Kedua metode-metode yang digunakan sama-sama memberikan  hasil yang optimal dalam mengatasi persoalan line balancing. Pada Metode Hegelson-Birnie dengan waktu siklus 30 detik diperoleh rata-rata efisiensi sebesar 93,33% dengan idle time 16 detik dan balance delay sebesar 6,67%, selain itu adanya pengurangan jumlah stasiun kerja dari 16 stasiun kerja menjadi 8 stasiun kerja. Sedangkan pada Metode Killbridge-Wester dengan waktu siklus 40 detik diperoleh rata-rata efisiensi sebesar 80,00% dengan idle time 56 detik dan balance delay sebesar 20%, selain itu adanya pengurangan jumlah stasiun kerja dari 16 stasiun kerja menjadi 7 stasiun kerja. Dari perbandingan kedua metode tersebut yang merupakan solusi terbaik di dalam penerapan metoda line balancing pada pembuatan T-Shirt di PT. Caladi Lima Sembilan (C-59) adalah metode Hegelson-Birnie.

PT XYZ merupakan salah satu perusahaan yang bergerak di bidang industri mebel. Masalah yang dihadapi perusahaan adalah adanya ketidakseimbangan di lintasan produksi akibat ketidakmerataan pembagian beban kerja di setiap stasiun kerja. Hal ini menyebabkan performansi keseimbangan lintasan (line performance) menjadi kurang baik. Untuk menyelesaikan permasalahan ini perlu dilakukan penyeimbangan lintasan produksi. Hal ini dapat dilakukan dengan metode line balancing yaitu metode penugasan sejumlah pekerjaan yang saling berkaitan dalam satu lintasan produksi sehingga setiap stasiun kerja memiliki waktu yang tidak melebihi waktu siklus dari stasiun kerja tersebut. Metode line balancing yang digunakan adalah metode heuristik yang terdiri dari: metode bobot posisi (Ranked Positional Weight), metode pembebanan berurut (Large Candidate Rule), dan metode pendekatan wilayah (Region Approach). Dari ketiga metode Heuristik yang digunakan sebagai solusi penyeimbangan lintasan, terjadi perbaikan performansi dengan nilai yang sama pada lintasan produksi. Nilai efisiensi lintasan (line efficiency) meningkat menjadi 94,07 % dari 62,71 % pada kondisi awal. Nilai keseimbangan waktu senggang (balance delay) turun menjadi 5,92 % dari 37,28 % pada kondisi awal. Waktu menganggur (idle time) turun menjadi 12,39 menit dari 116,87 menit pada kondisi awal. Nilai smoothness index juga turun menjadi 7,44 dari 64,67 pada kondisi awal. PT XYZ is one of the company which refers to furniture industries sector. The problem which faced by this company is unbalance of the production line which is caused by the unequal of work responsibility distribution in each work station. This problem caused the performance of line balance doesn’t work properly. To solve this problem we need to do the line balancing of production line. It can be done by line balancing methode that assigns a number of work which is related in one production line until each work station has efficient time which is not more than the cycle time of the work station. Line balancing methode that used is heuristic methode which is devided into ranked positional weight methode, large candidate rule methode, and region approach methode. From those three heuristic methode that used as solution of line balancing, there was improvement happenned with the same value in doors of production line. Line efficiency increased into 94,07% from 62,71% at the beginning condition. Balance delay increased into 5,92% from 37,28% at the beginning condition. The idle time descreased into 12,39 minutes from 116,87 minutes at the beginning condition. The smoothness index descreased into 7,44 from 64,67 at the beginning condition.

Feeding Speed

The purpose of this paper is to improve line productivity using line balancing technique and a reduction of work variation using an automated part feeder. This is due to the fact that the conventional assembly line manually feeds a part on to the production line by a worker. The feeding cycle is not constant and varies from time to time. Thus, the production rate is not constant and varied by the worker feeding speed. In addition, the assembly line itself does not fully balance. The operation time of each station is not well designed; as a result, all of the stations but the bottle-neck one experience an idle time. The balance efficiency is only at 40.33 percent which means that 59.67 percent of the total production time is balanced delay. Once the automated feeding machine which a buffer is designed and implemented. The cycle time can be set at 6 sec. and with the line balance technique the operator can be reduced from 11 to 9 persons. As a result, the productivity is substantially increasing around 138 percent and the new balance efficiency is 85.12 percent.

<p><em>Line balancing is a jobs assignment into a number of work stations that are interrelated in a track or a production line with an objective to minimizing the idle time on the line that is determined by the slowest operation. In line welding 1DY models includes eight work stations where one work station is done by one operator. Problems have been found that these operators have very long idle time and also there is too much wip that creates bottleneck in the production line so these leads to a waste of manpower and time. This waste of manpower and time need to be reduced by determining the optimal amount of labor in order to avoid excessive idle time but work can be done effectively and efficiently. One way to adress imbalance line is to apply line balancing methods.The results of this research shows that the line balancing methods can reduced the waste of time and give solutions for the optimal amount of labor requirements for line welding 1DY models.</em></p><p>Keywords: Line Balancing, Workstation, Production Line, Idle Time, Bottleneck.</p><p><em><br /></em></p>
