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

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.

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.

New Criteria

Purpose The purpose of this paper is to define new criteria for measuring workload smoothness of two-sided assembly lines and propose an algorithm to solve a two-sided assembly line balancing problem focusing on distributing the idle time and the workload as evenly as possible among the workstations. Design/methodology/approach This paper points out that the mean absolute deviation (MAD) and the smoothness index (SI) used to measure the workload smoothing in one-sided assembly lines are both inappropriate to evaluate the workload balance among workstations in two-sided assembly lines, as the idle time occur at the beginning and in the middle of a cycle within workstations. Then, the finish-time-based SI and MAD (FSI and FMAD) are defined, and a heuristic procedure based on the core mechanism of Moodie and Young method is proposed to smooth the assembly workload in two-sided assembly lines. Findings The computational results indicate that the proposed heuristic algorithm combined with the FMAD is effective in distributing the idle time and the workload among workstations as evenly as possible in two-sided assembly lines. Practical implications The two-sided assembly line balancing problem with the objective of the line efficiency can be effectively solved by the proposed approach. Originality/value The FMAD is proposed to effectively improve the workload smoothing in two-sided assembly lines.

<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>

The experimental efficacy of a work station that is ergonomically designed owes its overall reliance on production engineering, especially considering assembly line balancing besides the sustained work output of the assembly line and its snags caused in the production process have been acknowledged since long. The manifestation of these irregularities and consequent inadequacies on persistent shoulder – neck exposure have been studied for this paper with the help of work aids. A conducive workplace based on better ergonomic work station design, influences stress decreased due to the undue strain of repeated actions in an assembly line situation. This makes for resultant assembly line need to get balanced and subsequent to the production most irregularities decrease. It also results in the perpetuation of idle time across the assembly line outputs as compared to when no work aids have been introduced.  Focus The researcher contribution of this paper is the experimentation conducted on a work table designed for the finishing line segment of the garment manufacturing assembly line. The folding table, as it has been called has flexibility of adjustment of work angle and some advantages over the conventional fixed surface tables.   Method Designing aspect apart this Table has been experimented with for usage and stability in the garment manufacturing assembling at three different units. The pilot results have been examined in the light of work done by earlier scholars.   Scope The musculoskeletal strain experienced by workers in the garment manufacturing units impacts directly on their work output resulting long term physical and socio-economic implications that tend to effect work output efficiency in the long run.   Results and Findings Decreased stress levels show indications of positive usage of this work aid. However, testing is still going on to confirm the preliminary results
