Abstract

Peningkatan penjualan televisi secara global berefek secara langsung pada pengingkatan jumlah produksi di industri perakitan televisi. Di sisi lain, peningkatan jumlah produksi televisi berdampak pada peningkatan jumlah cacat produk yang terjadi akibat proses perakitan. Human error merupakan salah satu penyebab terjadinya cacat produk pada proses perakitan televisi. Selama ini, analisa yang dilakukan pada produk cacat akibat dari human error hanya bersifat asumsi dan corrective. Perusahaan manufaktur televisi tidak melakukan analisa secara detail terhadap potensi human error pada setiap proses perakitan televisi, serta menganalisis hubungannya dengan cacat produk yang terjadi pada proses perakitan televisi. Guna mengukur nilai human error pada proses perakitan televisi, digunakan Human Reliability Analysis (HRA) untuk mengukur keandalan manusia dalam proses perakitan televisi. Metode HRA yang digunakan adalah Standardized Plant Analysis Risk – Human Reliability Analysis (SPAR-H). SPAR-H digunakan untuk menghitung nilai Human Error Probability (HEP) pada setiap stasiun perakitan televisi. Nilai HEP dari setiap stasiun perakitan kemudian dikorelasikan dengan data cacat produk yang terjadi pada tahun 2022, hal ini dilakukan untuk mengetahui hubungan nilai HEP dengan cacat produk yang terjadi pada proses perakitan televisi. Hasil penelitian menunujukan bahwa proses pemasangan FFC (Flat Flexible Cable) memiliki nilai HEP tertinggi yaitu sebesar 0,12, nilai ini lebih tinggi dibandingkan proses lain. Nilai HEP dengan cacat produk menunjukkan hubungan yang positif dan kuat, dengan koefisien korelasi 0,724. Nilai HEP juga berpengaruh sebesar 52,5% terhadap cacat produk yang terjadi pada proses perakitan televisi. Proses pemasangan FFC memiliki nilai HEP tertinggi karena bentuk FFC yang pipih dan sensitive. Faktor penyebab lain adalah serta kurangnya pelatihan terhadap pekerja pemasangan FFC. Untuk mengurangi resiko terjadinya cacat produk, rekomendasi perbaikan yang disarankan pada penelitian ini adalah peningkatan frekuensi pelatihan kepada pekerja pemasangan FFC, penambahan metode pelatihan dengan komparasi video, dan pemindahan proses pemasangan FFC ke Sub-Assembly line.

The increase of television global sales has direct effect on increasing the amount of production in the television assembly industry. On the other hand, the increase in the number of television production have impact to increase in the number of product defects that occur on the assembly process. Human error is one of the causes of product defects in the television assembly process. So far, the analysis carried out for defective products is only assuming and corrective. Television manufacturing companies do not carry out a detail analysis of the potential for human error in each television assembly process and analyzing the relationship with product defects. To measure the value of human error in the television assembly process, Human Reliability Analysis (HRA) is used to measure human reliability in the television assembly process. The HRA method that uses is Standardized Plant Analysis Risk – Human Reliability Analysis (SPAR-H). SPAR-H is use to calculate the Human Error Probability (HEP) value at each television assembly station. The HEP value from each assembly station then correlated with product defect data that occurred in 2022. This was done to determine the relationship between the HEP value and product defects that occurred during the television assembly process. The research results show that the FFC (Flat Flexible Cable) installation process has the highest HEP = 0.12, this value is higher than other processes. The HEP value with product defects shows a positive and strong relationship, with a correlation coefficient of 0.724. The HEP value also has an effect of 52.5% on product defects that occur during the television assembly process. The FFC installation process has the highest HEP value because the FFC shape is flat and sensitive. Another contributing factor is the lack of training for FFC installation workers. To reduce the risk of product defects, the recommended improvements suggested in this research are increasing the frequency of training for FFC installation workers, adding training methods with video comparisons, and moving the FFC installation process to the Sub-Assembly line.
