KOMPONEN KIMIA DAN KETAHANAN EMPAT JENIS ROTAN

Abstract

Daemonorops fissa Khorthalsia flagellaris Korthalsia angustifolia Calamus unifarius Dinoderus minutus Daemonorops fissa Khorthalsia flagellaris Korthalsia angustifolia Calamus unifarius Daemonorops fissa Korthalsia flagellaris Korthalsia angustifolia Calamus unifarius Dinoderus minutus Tujuan penelitian ini adalah untuk mengetahui komponen kimia dan ketahanan empat jenis rotan terhadap serangan bubuk kering sebagai dasar pemanfaatan untuk pembuatan mebel dan peralatan rumah tangga. Jenis rotan yang diteliti yaitu wira ((Miq.) Bl., dahanan (Miq.), ahas (Bl.) dan kertas (H. Wendl.), Kalimantan Tengah dan Sumatera Selatan. Penentuan komponen kimia menggunakan standar TAPPI dan ASTM, sedangkan ketahanan terhadap bubuk Fabr digunakan contoh uji berupa rotan berukuran panjang 2 cm. Hasil penelitian Two of most important basic properties of rattan in furniture and household manufacturing are chemical compound and resistance to powder post beetles. This study examined the two basic properties of four rattan species which are currently less utilized. The four species, namely (Miq.) Bl or rotan wira, Miq. or rotan dahanan, Bl. or rotan ahas and H.Wendl or rotan kertas, were collected from Central Kalimantan and South Sumatera. Chemical compound was determined following TAPPI and ASTM standards. Resistance to powder post beetles (Fabr.) was tested using 2cm length samples. Results indicated the cellulose and lignin components of the four rattan species are as follow: (Miq.) Bl: 48.00% cellulose and 28.28% lignin, Miq.: 53,0% cellulose and 22,90% lignin, Bl.: 46,49% cellulose and 25,46% lignin, and H.Wendl: 27,10% cellulose and 27.10% lignin. Testing on resistance to powder post beetles showed that (Miq.) Bl and Miq. belong to class II, while Bl. and H.Wendl belong to class III. Thes results sugges the four rattan are appropriate as raw material for furniture fabrication and accessories to provide added value of particular products.
