dc.description.abstractModifikasi cat dan notching merupakan alternatif untuk mengembangkan teknik peningkatan mutu kayu. Pemberian cat larut minyak dan notching terbukti memberikan pengaruh pada karakteristik permukaan kayu eropa Scots pine (Pinus sylvestris), Robinia/Black locust (Robinia pseudoacacia), Norway spruce (Picea abies), dan Beech (Fagus sylvatica). Penelitian ini bertujuan menganalisis pengaruh perlakuan cat dan notching terhadap karakteristik permukaan kayu eropa sebelum dan sesudah weathering 12 bulan. Hasil penelitian menunjukkan kayu yang diberi perlakuan cat dan notching menyerap lebih banyak air dan memiliki permukaan lebih kasar akibat perlakuan notching yang tidak seragam. Modifikasi ini juga menyebabkan kayu Beech dan Scots Pine (gubal) terserang jamur. Selain itu, kayu dengan perlakuan cat dan notching memiliki nilai energi bebas permukaan (Surface Free Energy-SFE) lebih tinggi. Cat alkid memiliki keterbasahan yang lebih baik daripada cat akrilik karena viskositasnya yang lebih rendah. Pemberian cat larut minyak pada kayu dapat menurunkan nilai keterbasahan karena sifatnya yang hidrofobik atau anti air. Kelima jenis kayu eropa pada semua perlakuan mengalami peningkatan nilai keterbasahan setelah uji weathering selama 12 bulan. Kata kunci: Karakteristik permukaan, kayu eropa, notching, pencuacaan.
dc.description.abstractPaint modification and notching are alternatives for developing wood quality improvement techniques. The application of oil based paint and notching has been shown to affect the surface characteristics of European Scots pine (Pinus sylvestris), Robinia/Black locust (Robinia pseudoacacia), Norway spruce (Picea abies), and Beech (Fagus sylvatica). This study aims to analyze the effect of paint treatment and notching on the surface characteristics of European wood before and after 12 months weathering. The results showed that the wood treated with paint and notching absorbed more water and had a rougher surface due to the non-uniform notching treatment. This modification also causes Beech and Scots Pine (sapwood) wood attacked by mold. In addition, wood treated with paint and notching has a higher surface free energy (SFE) value. Alkyd paints have better wettability than acrylic paints cause of its smaller viscosity. Applying oil soluble paint to wood can reduce the wettability value due to its hydrophobic or water repellent properties. The five types of European wood in all treatments experienced an increase in wettability values after the 12-month weathering test. Keywords: European wood, notching, surface characteristics, weathering.
