PENGGUNAAN PUPUK NPK MUTIARA UNTUK PENINGKATAN PERTUMBUHAN TANAMAN GAHARU Aquilaria spp PADA LAHAN TERBUKA DI TANAH ULTISOL
Get PDFGaharu plants (Aquilaria spp.) can only be grown under shade in the first stage of the plant because this plant has a semi-tolerance silvens. This condition of gaharu make difficult to grow under the open, so it’s needed the applying of Mutiara NPK fertilizer. This study aims to determine the effect of NPK Mutiara fertilizer on the growth of gaharu in open field. The research was conducted at Trial Garden of Tanjungpura University in Pak Laheng Village, Toho Sub-District, Mempawah District until the plants are12 weeks old. Research Methods used Completely Randomized Design (RAL). Treatment of the research consisted of: without NPK Mutiara fertilizer;NPK Mutiara 50 gram/plant; and NPK Mutiara 100 gram/plant, with six replications/handling. The results showed that at the age of 12 weeks, Mutiara NPK fertilizer can accelerate the growth of height, diameter and number of leaves. The best dose of fertilizer to accelerate plant growth is 100 grams/plant.Keywords: Aquilaria spp, NPK Mutiara Fertilizer, and Ultiso

PEWARNAAN KAYU SENGON (Paraserianthes falcataria Linn) DARI EKSTRAK LIMBAH KULIT KAYU BAKAU (Rhizophora apiculata Blume) : UJI KETAHANAN WARNA DAN KEAWETAN KAYU
Get PDFSengon (Paraserianthes falcataria Linn) wood is widely used as a particular furniture and craft materials due to many supply and low cost. But Sengon wood has a color that tends to be white and has a low-grade durable IV-V. Mean while the bark of Rhizophora apiculata Blume mangrove was unutilized and made a huge waste, so its need optimal handling. Staining of sengon wood from mangrove bark extract is expected to provide new innovations in increasing the value of environmentally friendly wood decorative and can increase the value of wood sengon timber. Natural dye extract of mangrove bark waste using concentration of 2.5%, 5%, 7%, and 10% dye solution applied on Sengon wood. The results showed that the color endurance at concentrations of 2.5% to 5% was quite good compared to the concentrations of 7.5% and 10%. This is proved by evidence of the value color change before the test with the color of wood after testing using hot and cold water. The highest termite mortality value occurred at a concentration of 10% and the lowest weight loss of the colored test sample was found at a concentration of 10%. At concentration 5% has shown the optimal result in increasing the durability value of Sengon wood which initially with class durable IV-V become class durable II. Dye extract of mangrove bark waste Rhizophora apiculata Blume can be used as dye and increased the durability value of Sengon wood with optimum concentration for the purpose of staining and durability of wood is at concentration 5%.Keywords: C. curvignathus, Concentration, Natural Dye, Sengon, Waste Mangrove Bar
