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.

The existence of operational balance in each production lines may decrease the idle time; it shows that the productivity is increasing therefore it increases the production rate. The issues existed in the production process of hollow Dakota 1730 in PT. XYZ were 3 departments, from the result of the first observation, there was a bottleneck from each department and each production did not achieve the required target. Therefore, this research would fix the production line. The method used was ranked /positional weight. Based on the data processing by the ranked positional weight method, gained the total of work station in the production process of hollow Dakota 1730 by the number of 2 work stations. From the result of efficiency balancing, gained 62.5% and balance delay value was 37.5%. it shows that the balance performance between each department increases significantly.

PT Indoroti Prima Cemerlang is one of the Food  industries which produces bread with a brand Mr. Bread. the company had problems with the balance of the production line, so that it cannot meet consumer demand, this causing the company to not able meet the production targets. The purpose of this study is to calculate the increase in line balancing and decrease in idle time and determine the optimum number of work stations in the production process of product sweetbread combination at PT. Indoroti Prima Cemerlang. The method used in this study was the Ranked Position Weight (RPW) method with the results obtained that the number of work stations is reduced to 5 work stations, the line efficiency increases to 40% and balance delay decreased to 60% with idle time reduced to 29.019 seconds.

PT. 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. Mas-ing-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. Dari hasil pengolahan data, dipilih metode Ranked Positional Weights sebagai metode rekomendasi yang mendapatkan line efficiency 90,27%, balance delay 9,72%, dan smoothnes index sebesar 19,56936

<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>

This paper explains the improvement of PT ZYX's productivity on the assembly line-A, using the production line balancing method. Four methods of line balancing were examined, namely, Ranking Positional Weight (RPW), Region Approach, J-Wagon and Kaizen. The selection of the most suitable method is made based on the reduction of number of workstation and cycle-time. Based on the result. Kaizen method shows better total cycle time, number of workstation, and number of operator required. This result is simulated using the 'Tecnomatix' software with the DES (Discrete Event Simulation) method.

Assembly line balancing is assumed to have fixed task within specified task time during the initial stage of the mass production. The problem of current case study of this assembly line was the production line cannot meet the expected output plan with imbalance station cycle time. In this paper, productivity study and line balancing is applied to improve production line of GGMG & CALICO. The desired cycle time defined using the Standard Time Data (STD) which required the person to perform assign task till completion by defining the performance rating of person. The proposed solution proved by the implementation analysis conducted in the research. The results showed that the productivity of production line which is tremendously increased within 50% after implementation. There are six factors identified during the study which are bottleneck stations, workpiece flow, line layout, ergonomic, resource assignment and buffer allocation.
