Penelitian ini membahas tentang analisis alokasi kerja lini perakitan sepeda motor listrik di PT Wika Industri Manufaktur dengan delapan stasiun untuk meningkatkan laju throughput. Jalur perakitan dianalisis menggunakan model holding time period yang menggunakan distribusi phase-type (PH) dan juga menggunakan model discrete event simulation (DES). Distribusi PH digunakan untuk memodelkan waktu operasi stasiun yang bersifat stokastik. Stasiun kerja dibagi menjadi waktu tugas dan kemudian digunakan sebagai input untuk membangun distribusi PH waktu operasi stasiun. DES digunakan sebagai pembanding untuk memvalidasi hasil perhitungan model holding time period PH. Tingkat throughput dapat ditingkatkan dengan merealokasi tugas kerja menggunakan line balancing, mengalokasikan buffer, atau menambahkan stasiun. Ada dua jenis metode line balancing yang digunakan yaitu metode balanced line dan metode unbalanced line (mengikuti bowl phenomenon). Hasil holding time period dan simulasi menunjukkan hasil yang serupa yang menunjukkan bahwa buffer lebih baik dialokasikan pada stasiun terbaru dengan kemungkinan pemblokiran yang tinggi, metode line balancing unbalanced line tanpa buffer memiliki hasil yang sedikit lebih baik, dan penambahan stasiun memberikan peningkatan yang linier. mempengaruhi laju throughput. Untuk line balancing dengan buffer, saluran yang seimbang lebih baik. ==================================================================================================
This research discusses about a work allocation analysis of an electric motorcycle assembly line in PT Wika Industri Manufaktur with eight-station to increase throughput rate. The assembly line is analysed using a holding time period model that uses a phase-type (PH) distribution and also using a discrete event simulation (DES) model. PH distribution is used to model the operation times of stations that are stochastic. Workstations is divided into task times and is then used as an input to construct the PH distribution of station operation times. DES is used as a comparison to validate the calculation results of the PH holding time period model. Throughput rate can be increased by reallocating work-tasks using line balancing, allocating buffers, or adding stations. There are two types of line balancing method used which are the balanced line method and the unbalanced line method (following the bowl phenomenon). The results of holding time period and simulation show a similar result indicating that buffers are better allocated at the latest station with high possibility of blocking, the line balancing unbalanced line method without buffers have slightly better results, and the addition of stations gives a linearly increasing effect to the throughput rate. For line balancing with buffers, the balanced line is preferable.
