Abstract

PT. Unisem Batam, khususnya pada mesin auto molding yang berfungsi untuk mengkapsulkan material leadframe dengan menggunakan compound supaya material tersebut kuat dan tahan panas. Kegiatan cleaning pada mesin auto molding juga perlu dilakukan oleh operator untuk membersihkan sisa-sisa compound yang terdapat pada cavity bar. Proses pembersihan cavity bar yang dilakukan oleh operator menimbulkan sisa compound yang terdapat pada belakang (didalam) mesin auto molding sehingga proses tersebut dilakukan pembersihan secara manual. Untuk mempermudah kegiatan pembersihan yang dilakukan oleh operator diperlukan pengembangan dengan menambahkan brush, desain papan lubang, dan penampungan sisa compound pada mesin auto molding. Kerja pada offloader berada di degate area dan mold area sehingga pada saat memproduksi material leadframe tersebut offloader dapat melakukan fungsi kerja tambahan dari pengambilan material leadframe dari mold area, peletakan material ke degate area, dan cleaning secara otomatis. Dengan pengembangan tersebut operator hanya memfokuskan pengisian compound secara manual untuk proses produksi material leadframe pada belakang mesin auto molding. Hasil penelitian yang didapatkan pada mesin auto molding didapat keseluruhan kerja yang dilakukan oleh salah satu bagian mesin auto molding, offloader dimana data didapat dari proses yang dilakukan pada offloader dari degate area dan 4 mold area. Dari data total yang didapat rata-rata untuk keseluruhan kerja pada offloader yaitu 24.9 detik dimana hasil tersebut dapat mempermudah kegiatan operator yang melakukan pembersihan secara manual antara 1-3 menit. ********************************************************************** PT. Unisem Batam, especially in the auto molding machine which functions to encapsulate leadframe material by using a compound so that the material is strong and heat resistant. Cleaning activities on the auto molding machine also need to be carried out by the operator to clean the remnants of the compound contained in the cavity bar. The cleaning process of the cavity bar carried out by the operator causes the remainder of the compound which is located at the rear (inside) the auto molding machine so that the process is carried out manually cleaning. To facilitate cleaning activities carried out by the operator, development is needed by adding brushes, hole board designs, and storing the remaining compound in the auto molding machine. Offloader is work in the degate area and mold area so that when producing the leadframe material the offloader can perform additional work functions from taking leadframe material from the mold area, laying material into the degate area, and cleaning automatically. With this development the operator only focuses filling the compound manually for the production process of the leadframe material on the back of the auto molding machine. The results of the research obtained in the auto molding machine obtained overall work done by one part of the auto molding machine, offloader where the data obtained from the process carried out on the offloader of the degate area and 4 mold area. From the total data obtained on average for the whole work on the offloader is 24.9 seconds where the results can facilitate the activities of operators who do manual cleaning between 1-3 minutes.
