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.

<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>

Time efficiency in production is very supportive of fulfilling consumer demand. The track balance problem can be solved by taking measurements first. This measurement aims to determine the parameters that cause an imbalance in the production line. The first step that needs to be done is measuring the track balance before optimization. Rank Postional Weight is heuristic’s systematic approach method is used to measure the balance of the car CVT belt production line in a grinding machine. The measurement results show that it is not good with a smothness index of 130.48 minutes, the product produced is only 97.5% of the set target, the performance of the work station is 80.56%. Improvements in several work stations in order to improve the balance of the trajectory, namely in visual checks, smoothing surfaces and shapes, measuring products by rearranging the order.

The development of the industrial world is getting tighter, making each company must be able to overcome productivity to meet consumer demand. In increasing productivity, of course, you must make the production process efficient. One thing that can be done is to make line balancing. The purpose of this study is to identify and propose a track balance to make the production process more efficient. The data used in this research is in the form of the initial conditions of the work station and the type of work. The method used to identify the optimal trajectory balance is the Ranked Position Weight (RPW). From the results of data processing, it is known that the initial conditions of work stations on the control panel assembly are 5 stations and 16 types of work. From the results of the calculation of cycle time and the number of stations, the optimal number of stations is reduced to 3 work stations. After calculating using the Ranked Position Weight method, it is known that the 16 types of work can be grouped into 3 work stations. Then the balance delay is obtained after reducing the work station, which is 5.48% from the initial condition of 43.29%. Then the line efficiency after station reduction is 94.52% from the initial condition of 56.71%. Then the smoothing index after improvement was 0.983 from the initial condition of 6.128. From the results of the three indicators, it can be seen that the reduction of the station gives better results.

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.

Purpose – The purpose of this paper is to improve the productivity of a large-sized frozen chicken manufacturer in Thailand. It analyses the production process based on work study principles and identifies the bottleneck operation. It develops three models for the chicken preparation process. Design/methodology/approach – First, analyse the current production system by collecting the cycle time of all operations in the production process based on work study principles. Then, design the production network and identify the bottleneck operation. After that, three methods – based on line balancing (LB), theory of constraints, and JIT concepts or ECRS (eliminate, combine, rearrange and simplify) – are proposed and implemented in the actual production line. Findings – With the ECRS concept, the authors implement combine by combining two stations into one station, such as handling and weighing, or weighing batter and mixing it with chicken. Then, Simplify is implemented at job E, or transporting chicken using a cart instead of walking. This method can improve the cycle time and reduce the number of employees. It can increase the line efficiency by up to 94.20 per cent, reduce the number of employees by 14 persons, and reduce the labour cost by 356,160 baht/year. Originality/value – Most agro-industry manufacturing processes are labour intensive. Thus, production LB can help increase productivity and reduce costs. The authors found that the case study company designed the production line without aligning it with the production network. A simple improvement can be made by adjusting the sequence of the work. In addition, the current production line was not lean. Implementation of the ECRS concept to improve production can reduce the waiting time and simplify the job.

Agung Mulya has experienced a decline in the production process, because there is an inefficient machine arrangement that causes delays in producing products, products with a target in a day can produce about 300 pcs of requests, can only produce about 170 pcs of requests, it is suspected that the main cause is the layout of the machine. less precise. In an effort to solve this problem, this study uses a method using Line Balancing and ARC (Activity Relation Chart) methods. This method is used for structuring the production flow so that there is a balance on all production lines so as to provide high efficiency on each production line. The balance in question is the balance of output from each stage of operation from the point of view of the production line and compiling a layout design for room facilities is used to analyze the proximity relationship using input data in the form of process flow, distance between spaces, conditions and spatial conditions From the results of this study resulted in a better re-lay out of thr production facility layout, the work station which originally had 8 workstations has decreased to 5 workstations, this is because the layout of the production flow layout can reduce the distance between work stations and the production process more efficient.
