AbstractLi3Y(BO3)2 was prepared by high-temperature solid state synthesis at 900°C in a platinum crucible from lithium carbonate, boric acid, and yttrium(III) oxide. The compound crystallizes monoclinically in the space group P21/c (no. 14) (Z=4) isotypically to Li3Gd(BO3)2. The structure was refined from single-crystal X-ray diffraction data: a=8.616(3), b=6.416(3), c=10.014(2) Å, β=116.6(2)°, V=494.9(3) Å3, R1=0.0211, and wR2=0.0378 for all data. The crystal structure of Li3Y(BO3)2 consists of [Y2O14] dinuclear units, which are interconnected to each other by planar B(1)O3 groups and LiO4 tetrahedra via common edges and corners along the a axis.

This research used the lesser known species as much 5 types rattan, consisted of i.e marau (Calamus Mettanensis Becc), toho (Calamus Spp), galang (Daemonorops Verticilaris Griff Mart), hijau (Calamus Spp) and simpurut (Calamus Panajuga Becc) from Central Kalimantan. Preservative used the mixture of boric acid with the borax and copper-8 by  the concentration of 1,0 %, 2,0 % and 3,0 %. Soaked time during 2 day, 4 day and 6 day by immersion chilled. Result of research indicated that the retention value varied, the greater of concentration condensation and soaking period, the greater average the value of retention while penetration result at all of treatment showed the value 100 %.Keywords:  rattan, preservation, retention, penetration, cold soaking.
