Abstract

Jackfruit plant (artocarpus heterophyllus lamk) is know as multipurpose tree. A chemical analysis of jackfruit wood from west java has been conducted to determine the contents of cellulose, lignin, pentosan,ash,silica and solubility in cold water, hot water, one percent sodium hydroxide and alcohol-benzene (1:2).The results showed that cellulose content 56,47 percent, lignin 28,76 percent, pentosan 18,64 percent, ash 0,78 percent, and silica 0,37 percent. Thesolubility in cold water 12.29 percent, hot water 14,41 percent, one percent sodium hydroxide 24,70 percent, and solubility in alcohol-benzene (1:2) 10,78 percent.

Abstract

This research was aiming at indentifying the tractor skidding capasity in logging operation in the natural production forest. The tractor observed was Komatsu D85E-SS. and in this study the specific gravity of 0.8 for all species was assumed.The results shows that the capasity of skidding was about 14. 7 ton or equal to 18, 40 m log. However, it was found that from 52 observations, 8% were done under the 20% capacity, 42% of the skidding were done under 21-40% capacity, 25% were done under 40% capacity and 8% were done by winching. .Those figures indicate that the skidder capacity has not yet fully utilized. Therefore, the possibility to increase the volume of skidding is widely open, meaning that the logging wastes can be overcome by skidding those above clear bole parts together with the main log.The cost of skidding per m3 compared with 20 years ago was found to be three times higher. The cost skidding per m3 was about Rp. 3225,- at the averege distance of 3,16 hm.

Abstract

Berdasarkan penelitian terdahulu senyawa lignin yang diantaranya terdapat dalam limbah pabrik pulp dapat digunakan untuk perekat kayu lapis eksterior. Untuk meningkatkan mutunya, pengaruh penambahan fenol untuk menghasilkan perekat lignin fenol formaldehida, dlteliti. Perlakuan lain yang diterapkan adalah pemakaian kadar paraformaldehida sebagai pengeras. Hasilnya menunjukkan bahwa sifat-sifat perekat lignin fenolformaldehida sesuai dengan perekat fenol formaldehida menurut Standar Indonesia. Pengaruh nisbah bobot berdasarkan nisbah mol dan kadar pengeras terhadap keteguhan rekat kayu lapis masing-masing sangat nyata. Umumnya, nisbah bobot lignin : fenol dari 1: 0,5 sampai dengan 1:2,5 dengan ketiga macam kadar pengeras, memenuhi persyaratan Standar Indonesia untuk kayu lapis eksterior (tipe I). Nisbah bobot lignin: fenol = 1:2,0 dan 1:2,5 dengan kadar pengeras masing-masing 4,5% tidak memenuhi persyaratan.Keteguhan rekat kayu lapis cenderung menurun bi/a penggunaan fenol makin banyak. Berdasarkan pertimbangan ekonomi, disarankan untuk menggunakan nisbah mol lignin : fenol = I: 0,5 dengan kadar pengeras 1,5 % dari berat perekat cair.

Abstract

 This paper presents  the result of test on machining properties  of 28 wood species from  Bogor and Sukabumi, West Java.  The test method used was the modified  ASTM  D-1666 described in the Forest Products  Research Institut  Report No.  160 (1982).   The samples  (25 pieces/species) were dried  to equilibrium moisture  content condition (15  to  18%).  The machining  properties   investigated   were planning, shaping, boring, mortising,  turning and sanding.The species that have good or very good machining properties  are kobari, pasang jambe,  pasang beureum,  mahoni  daun lebar, pentadesma, cloropora,  eucalyptus,  meranti  batu,  pinus  I, mahoni,  mahagoni  and pinus  III.  Species such  as kelumpang,  entorolobium   and  cecropia  are consistenlly poorer. The other species are good in some properties  and fair or poor  in others.

Abstract

Kayu karet (Hevea brasiliensis M11ell. Arg.) sangat rentan terhadap seranggapen1sak terutama b11b11k kayu kering Heterobostrychus aegualis Wat., rqyap tanah Coptotermes curvignathus Ho/mgr. dan rayap kayu kering Cryptotermes cynocephalus Light. Untuk menghindarkan serangan serangga perusak tersebut, kayu karet harus diberiperlateuan tertentu. Beberapa percobaan eftkasi penggunaan beberapa jenis babanpe lapis (cat), yang banyak tersedia di pasaran, telah dilakukan untuk pencegahan serangan serangga perusak tersebut. Untuk penelitian terhadap bubuk kayu kering, papan kayu karet yang telah kering oven segera dipotong menjadi contoh uji ukuran 10 x 5 x 2,5 cm. Permulaan contoh uji dilabur sebagian atau seluruhnya dengan bahan pelapis. Contoh uji tersebut kemudian disimpan secara acak di antara tumpukan kayu karet yang telah diserang bubuk kayu kering agar terjadi penularan. Contoh uji yang lain, ukuran 2,5 x 2,5 x 2,5 cm, setelah dilapisi seluruh permukaannya dengan baban-baban tersebut diumpankan ke rayap tanah atau rayap kayu kering masing-masing selama 4 dan 12 minggu. Hasil penelitian menunjukkan bahwa pelapisan seluruh permukaan dapat meningkatkan daya tahan kayu karet terhadap serangan bubuk kayu kering. Pelapisan dengan Melamine memberikan hasil terbaik, dalam waktu lebih dari tiga tahun belum menunjukkan adanya kerusakan yang berarti Namun demikian, perlakuan tersebut ternyata tidak efektif untuk pencegahan serangan kedua jenis rayap tersebut.

Abstract

Emisi formaldehida dan sifat fisis-mekanis dari papan partikel yang direkat dengan urea formaldehida (UF) dapat mengganggu kesehatan, terutama jika digunakan di dalam ruangan dengan ventilasi terbatas. Untuk mengurangi emisi formaldehida, dapat digunakan suatu adsorben ke dalam perekatnya. Dalam tulisan ini diuraikan pengaruh penggunaan arang aktif dalam campuran perekat urea formaldehida terhadap emisi formaldehida dan sifat fisis-mekanis papan partikel daur ulang serta aspek ekonominya. Hasil penelitian menunjukkan bahwa pemakaian arang aktif mempengaruhi emisi formaldehida dan sifat fisis-mekanis papan partikel. Aplikasi arang aktif sebanyak 3% pada perekat urea formaldehida mampu mengurangi emisi formaldehida dan meningkatkan sifat fisis-mekanis papan partikel serta memenuhi persyaratan standar Indonesia dan Jepang, dan layak secara finansial.

Abstract

The physico-chemical properties and identification of new essential oils from Cinnamomum subavenium Miq (Sabal-sabal) bark prepared by using vacum destillation process is presented in this paper. The bark used was subjected to three different position i e : top, middle and bottom. The physico-chemical properties observed are specific gravity, acid value, ester conent, solubility in ethanol 80 % refractive index at 20°C, and optical rotation. The major components of essential. oils were identified by using peak enrichment technique and retention data from essential oil standart of the Gas Liquid Chromatographic method. In addition, the-yield was determined.The result shows that the yield ranges from 1. 73 - 1. 87 % specific gravity at 25°C from 0. 93689 - 0. 94454, refractive index at 20°C from 1.47966- 1.48542, optical rotation at 25°C from -11°9' to -12°39', acid value from 1,02 – 1.34, ester content from 6.45 - 8.29 and solubility in ethanol 80 % is soluble in 1:1. The composition of major components of the Sabal-sabal oil were iso borneol ranges from 17.75 - 22.15 %, aldehyde C-II from 6.09-17.ll %, cineol from 13.20- 14.23 %, iso bornyl acetate from 5.28 -8.47 %, a terpinyl acetale from 5.21 - 8.81 %. Furthermore some components found in the oil were a pinen, β pinen, terpinene , β caryophyllene, aldehyde C-9, cinamaldehyde and hidroxy citronellol Based on major components and its derivatives the oil is used in the perfumery and flavor industry.

Abstract

Fifteen  wood species from  Irian  Jaya  with sample  test pieces  measuring  5 x 5 x  60 cm,  and  water content  from 20. 0-21.4 percent, were subjected  to cold soaking  treatment,  using 5 and 10 percent  concentration  of BFCA  preservative,  for  three, five  and seven  days. Taking into account  the penetration  and retention  requirement for  wood use condition  under roof and outdoor,  without ground contact,  the result indicates that matoa  wood could not be treated  with the schedule proposed  in this paper.  The other fourteen   wood species could be treated with any of the treatment schedule (Table 4). However,  two species (honggimako  and senai) meet only the requirement for  use under roof  without ground  contact.
