Abstract
Pada penelitian mengenai rancang bangun alat dip coater telah dilakukan pembuatan desain dan realisasi alat tersebut untuk skala laboratorium. Yang mana total biaya bahan yang dibutuhkan sebesar Rp5.696.419,00. Nilai tersebut dibawah harga rancangan alat penelitian terdahulu dan produk komersil di pasaran. Alat dip coater yang telah didesain dan direalisasikan memiliki ukuran dimensi luar (80 × 46 × 85) cm dengan dimensi kerja bagian dalam yaitu (50 × 23 ×52) cm. Pengguna alat dip coater dapat melakukan monitoring dan memberikan masukan nilai kontrol melalui display yang ada. Adapun spesifikasi alat untuk proses dip coating yang telah diujikan yaitu memiliki nilai minimal kecepatan gerak linier (0, 575 ± 0, 001) mm.s−1. Kemudian nilai kontrol kedalaman pencelupan pada skala cm. Kontrol waktu yang memiliki standar deviasi orde 7. Lalu kontrol pemanasan pada alat dip coater membutuhkan waktu 3,5 menit untuk mencapai suhu (30 ± 1)◦C dan 40 menit untuk mencapai suhu (40 ± 1)◦C dari suhu mula-mula (25 ± 1)◦C. Spesifikasi mekanik alat dip coater telah dibuktikan kehomogenan suhu yang merata disebaran ruangnya. Komponen penggerak substrat juga telah disimulasikan static structural dengan beban 30 N memiliki nilai total deformasi maksimum 2, 9662 mm dengan rerata 0, 52276 mm.

In research on the design of dip coater tools, the design and realization of these tools has been carried out for laboratory scale. Where the total cost of materials needed is IDR 5,696,419.00. This value is below the price of previous research tool designs and commercial products on the market. The dip coater tool that has been designed and realized has an outer dimension of (80 × 46 × 85) cm with an inner working dimension of (50 × 23 ×52) cm. The user of the dip coater tool can monitor and provide control value input through the existing display. The tool specifications for the dip coating process that have been tested have a minimum value of linear motion speed of (0, 575 ± 0, 001) mm.s−1. Then the control value of the dipping depth on the dip coater is 0, 575 ± 0, 001 mm.s−1. Then the immersion depth control value on a centimeter scale. Time control which has a standard deviation of order 7. Then the heating control on the dip coater tool takes 3.5 minutes to reach a temperature of (30 ± 1)◦C and 40 minutes to reach a temperature of (40 ± 1)◦C from an initial temperature of (25 ± 1)◦C. The mechanical specifications of the dip coater tool have been proven to have a uniform temperature distribution in its space. The substrate drive component has also been simulated static structural with a load of 30 N having a maximum total deformation value of 2,9662 mm with an average of 0, 52276 mm.
