IDENTIFIKASI MODEL ARSITEKTUR JENIS POHON FAMILI LAURACEAE DI KAWASAN ARBORETUM SYLVA UNIVERSITAS TANUNGPURA PONTIANAK
Get PDFThe tree architecture model is one of the important morphological features of the plants in characterizing each tree. Trees are plants with woody stems, deep roots, and have branches far from the ground and are more than 3 meters high (Hakim and Utomo 2003). trees are also one of the soft elements (softcape) that are very often used in the development of a site or landscape with a variety of unique characteristics. One of the unique characteristics of a tree is the dominant form of tree architecture formed by its canopy. This research was carried out at the Sylva Arboretum in Tanjungpura Pontianak for 3 weeks starting from July 4 2018 to July 24 2018 to observe and identify the architectural model of the lauraceae family tree. The research objective was to determine the architectural model of the Lauraceae family tree in Sylva Arboretum in Tanjungpura University Pontianak. The research method used is the exploration method, which is done by roaming, which means that observations can be made with visual and physical contact. Based on the results of the research and discussion, lauraceae family tree architecture models found in the Arboretum Sylva Area of Tanjungpura University Pontianak as many as four architectural models namely Rauh, Roux, Petit and Scarrone. The four architectural models were found in six species of trees, namely Ulin (Eusideroxylon zwageri), Medang sahung (Achiodaphne glabra), Medang pasir (Litsea eliptica), Medang bubur (Litsea resinosa), Medang sisik (Dehaasia firma), and Kayu manis (Cinnamomum iners).Keyword: Family of Lauraceae, Model of Tree Architecture, Sylva Arboretu

Get PDFThis study aims to examine the physical and mechanical properties of gypsum board from Acacia mangium Willd wood waste based on gypsum content and wood powder size. This study refers to the JIS A 5417-1992 standard. This research were conducted at Wood Work Shop laboratory for the preparation of raw materials, Wood Technology laboratory Faculty of Forestry for board making and testing the physical properties of gypsum boards, and PT. Duta Pertiwi Nusantara laboratory to test the mechanical properties of the gypsum board. The material used is A. mangium W. Wood powder, gypsum flour, water and borax. The study uses Factorial Completely Randomized Design (CRD) with two factors, namely factor A (gypsum content) which consists of gypsum content of 400%, 500% and 600% of the weight of A. mangium W. wood powder, and factors B (wood powder size) consists of 20 mesh passes 40 mesh retained and 40 mesh passes 60 mesh retained. The results showed that the density (600% gypsum content of 40 and 60 mesh retained wood powder size), moisture content, thickness swelling, MOE (600% gypsum content of 40 and 60 mesh retained wood powder size) fulfill JIS A5417-1992 standard. The best gypsum board is gypsum board with gypsum content of 600% with a wood powder size is 40 mesh.Keyword: Acacia mangium, gypsum board, gypsum content, wood powder size
