Abstract
English
The blasting process in the shipping sector aims to remove dirt, rust and factory scale from the plate surface and to create roughness on the surface so that the paint layer can adhere well. In the blasting process, abrasive materials are generally used once or twice. However, in field practice, reused copper slag has been used as an abrasive material. This study aims to analyze the surface roughness level of the plate during the blasting process using the Analysis of Variance (ANOVA) method with variations of new copper slag, reused copper slag 1 and 2 with cleanliness standards according to ISO 8501-1 SA 2.5 and the standard surface roughness level of the plate according to IMO-PSPC (Performance Standard for Protective Coatings) with a surface roughness level ranging from 35 µm – 75 µm. From the results of the data analysis, it shows that the reuse of copper slag during the blasting process, the roughness level obtained is getting smaller. Therefore, the surface roughness level of the plate that meets the IMO-PSPC standard which ranges between 35µm-75µm is copper slag reuse 2 and while the maximum limit of the surface roughness level of the plate that meets the IMO-PSPC criteria is copper slag reuse-3.

Proses blasitng dalam sektor perkapalan bertujuan untuk menghilangkan kotoran, karat dan kerak pabrik dari permukaan pelat serta untuk menciptakan kekasaran pada permukaan sehingga lapisan cat dapat melekat dengan baik. Dalam proses blasting, materialabrasif umumnya digunakan satu atau dua kali. Namun, dalam praktik lapangan, telah digunakan penggunaan ulang copper slag sebagai material abrasif. Penelitian ini bertujuan untuk menganalisis tingkat kekasaran permukaan pelat selama proses blasting menggunakan metode Analisis Varians (ANOVA) dengan variasi copper slag penggunaan baru, copper slag penggunaan ulang 1 dan 2 dengan standar tingkat kebersihan sesuai dengan ISO 8501-1 SA 2.5 serta standar tingkat kekasaran permukaan pelat menurut IMO-PSPC (Performance Standard for Protective Coatings ) dengan tingkat kekasaran permukaan berkisar antara 35 µm – 75 µm. Dari hasil analisis data menunjukkan bahwa penggunaan ulang copper slag pada saat proses blasting maka tingkat kekasaran yang didapatkan semakin kecil. Maka, tingkat kekasaran permukaan pelat yang sesuai standar IMO-PSPC yang berkisar antara 35µm-75µm adalah copper slag penggunaan ulang 2 dan sementara batas maksimum tingkat kekasaran permukaan pelat yang sesuai dengan kriteria IMO-PSPC adalah copper slag penggunaan ulang-3.
