Botanical Garden including information on their physical and mechanical properties, natural durability, distribution, prospect and other supporting data; (2) to analyze the lesser-known wood species that could be used for construction materials and then recommend them to be developed through Industrials Plantation Forest. The steps of the study were first collection of data on timber species from herbarium catalogue; second collection of data on the properties of wood from various sources; third, observation of stem morphology in the field. The result of the catalogue study showed that there were 291 timber tree species grown in Cibodas Botanical Garden which were comprised of 14 major commercial timbers, 74 minor commercial timbers, and 142 lesser known timbers. These timber species were also distributed in other parts of Indonesia. Observation in the field then generated 49 lesser-known wood species that could be used for construction materials based on their stem form and branch height. From the reference and catalogue study, it was found that there were 14 wood species belongs to strength class I to III with natural durability ranges from very durable to moderate. These woods were then evaluated based on their morphological features and prospects. Finally, it was found that only ten wood species that were suitable to be used for construction materials, i.e. Acmena acuminatissima (Blume.) Merr. & Perry (Kelat); Adenanthera microsperma Teijsm. & Binn. (Saga); Baccaurea parviflora (Muell. Arg.) (Setambun); Casuarina junghuhniana Miq. (Cemara Gunung); Garcinia parvifolia and G. beccari (Manggis Hutan); Gymnostoma sumatranum (Joogb. ex de Vriese) L.A.S. Johnson (Cemara Sumatra); Mimusops elengi L. (Tanjung); Neonauclea lanceolata and N. obtusa (Ki Anggrit). However, the result of this study needs to be supported by further study on their wood properties since the present data were mostly qualitatives. Further research concerning their silviculture, growth rate, and susceptibility to the diseases were also needed to be done. Keywords : Lesser-known timbers, Cibodas Botanical Garden.

Berkembang pesatnya persaingan usaha perbankan membuat bank-bank baru bermunculan dan berlomba-lomba menarik dana dan menyalurkannya kepada masyarkat. Hal ini membawa pengaruh besar terhadap industri perbankan baik dalam peningkatan volume usaha dan jenis produk yang ditawarkan. Dengan bertambahnya jumlah bank, persaingan untuk menarik dana dari masyarakat semakin meningkat. Dana yang berhasil dihimpun dari masyarakat biasanya disimpan dalam bentuk giro, deposito dan tabungan. Dana yang berhasil dihimpun dari masyarakat sebagian besar dialokasikan untuk kredit. Karena kegiatan pemberian kredit kepada masyarakat merupakan rangkaian kegiatan utama suatu bank, dimana pemberian kredit adalah tulang punggung kegiatan perbankan. Namun dalam situasi perekonomian tidak menentu dan penuh dengan ketidakpastian, pemberian kredit oleh bank kepada masyarakat sedikit tersendat. Pengalaman adanya kredit macet akhir-akhir ini telah memacu kalangan perbankan untuk lebih berhati-hati dalam mengatur alokasi dananya pada kredit. Oleh karena itu kalangan industry perbankan saat ini cenderung lebih menyukai untuk mengalokasikan dananya dalam bentuk cadangan sekunder yang dalam hal ini dialokasikan pada surat-surat berharga terutama pada Sertifikat Bank Indonesia (SBI). Tujuan penelitian ini adalah: 1.Untuk mengetahui pengaruh secara simultan antara variabel jumlah Giro, Deposito dan Tabungan masyarakat terhadap perkembangan jumlah Sertifikat Bank Indonesia (SBI).2. Untuk mengetahui pengaruh secara parsial antara variabel jumlah Giro, Deposito dan Tabungan masyarakat terhadap perkembangan jumlah Sertifikat Bank Indonesia (SBI).3. Untuk mengetahui variabel yang paling dominan antara variabel jumlah Giro, Deposito dan Tabungan masyarakat terhadap perkembangan jumlah Sertifikat Bank Indonesia (SBI). Hasil yang diperoleh: 1. Ditemukan hasil analisa regresi linier berganda, yaitu Y = 379.966,018 + 19,289 X1 + 11,602 X2 – 15,599 X3.2. Ditemukan ada pengaruh signifikan secara simultan antara jumlah Giro, Deposito dan Tabungan terhadap jumlah Sertifikat Bank Indonesia (SBI).3. Ditemukan ada pengaruh signifikan secara parsial antara jumlah Giro dan Deposito terhadap jumlah Sertifikat Bank Indonesia (SBI).4. Variabel yang paling dominan antara jumlah Giro, Deposito dan Tabungan terhadap jumlah Sertifikat Bank Indonesia (SBI) adalah Giro.

Plantation waste has gained increasing attention as an alternative raw material for use in the manufacture of composite boards, i.e. waste of sago plantation. Medium density composite boards were made from zephyr of sago midrib to evaluate the effects of resin and adhesive content levels. The boards were fabricated using polyurethane (PU) and phenol formaldehyde (PF) resin with three levels of adhesive content i.e. 10%, 12%, and 14%. Physical (moisture content, density, water absorption, and thickness swelling) and mechanical (Modulus of Rupture, Modulus of Elastisity, Screw Holding, and Internal Bonding) properties of composite board were evaluated according to JIS A 5908-2003 standard. Research result showed that properties of composite board made from sago frond with 14% content level of polyurethane adhesive better than other composite board. Based on composite board properties, the board was suitable as building raw material and furniture i.e. partition, cupboard, table, and roof.

This paper deals with manufacturing and modification of pilot-scale wood bending machine by heating elements. The machine has specifications as follows: 1000 mm width; 1305 mm height; 430 mm and 470 mm radius of upper part and bottom part of bent plates, respectively; and a manual stick pressure with 870 mm length. The upper part and bottom part of bent plates are equipped with heating elements, which the maximum of temperature is arranged to 200°C by the electric force of 220V/2000 watt. Left and right sides of bent plates are covered by 1150 mm x 950 mm insulation board to maintain the heat. From the temperature measurement, the heating plates were reached 50°C in 2.5 minutes, 100°C in 9.5 minutes, and 180°C in 28 minutes. The modified machine has successfuly bent Acacia solid wood with dimensions of 1100 mm(L) x 50 mm(T) and 10 mm, 20 mm, and 30 mm in thickness (R).

The fiber and chemical characteristics of branchwoods of three meranti species namely meranti sangkan, meranti bakau, and meranti bunga kulit hitam from Bukit Batu Peat Swamp Forest, Riau were observed. The aim of this research was to discover the potential utilization of these three meranti species based on their characteristic. The result showed that holocellulose contents of meranti sangkan, meranti bakau, and meranti bunga kulit hitam were 72.97%, 75.28%, and 69.88%, whereas the α-cellulose contents were 43.55%, 51.14%, and 43.25%, respectively. meranti sangkan had the highest lignin content (35.99%) followed by meranti bakau (34.21%) and meranti bunga kulit hitam (32.18%). meranti Bunga kulit Hitam had the highest extractive content (2.24%) followed by meranti sangkan (1.66%) and meranti bakau (1.08). Furthermore, the fiber length of meranti bunga kulit hitam, meranti sangkan, and meranti and meranti Hitam were 1475.45 μm, 1475.45 μm, 1442.62 μm, and 1205.23 μm, respectively. The values of fiber derivative of the three meranti species were slightly differ from class I, except for felting power that was classified in class III. The result also showed that the branchwoods of the three meranti species are suitable for pulp and paper raw material.Key words: fiber and chemical properties, meranti bakau, meranti sangkan, meranti bunga kulit hitam, peat swamp forest
