Abstract

Tiga pohon mahoni berumur 12, 21, dan 30 tahun diambil secara acak dan butan tanaman. Dari ketiga log kayu tersebut dibuat contoh ttji berukuran 2,5 cm x 5 cm x 30 cm. Contoh ttji diawetkan dengan larutan CCB konsentrasi 3% melalui proses selpenuh dengan tekanan 10 atmospher selama 2 jam. Contoh yang diawetkan dan yang tidak diawetkan ditlji terhadap penggerek kayu di laut selama 3 dan 6 bulan. Hasil penelitian menunjukkan bahwa contoh ttji yang tidak diawetkan mendapat serangan penggerek di laut. Sebaliknya, yang diawetkan dengan CCB sangat taban, terutama contoh ttji yang diambil dari pohon yang berumur 12 tahun. Penggerek yang menyerang adalah Martesia striata Linne. Dari Jamili Pboladidae, Teredo bartchi Clapp., Dicyathifer manni Wright., dan Bankia cieba Clench./Turner. Dari Jamili Teredinidae. Pada contoh ttji juga ditemukan crustacea yaitu Sphaeroma sp. Dari Jamili Sphaeromatidae.

Abstract

This paper presents results of laboratory study  on the rate of moisture  content  decrease of 19 timber species.  The test specimen from each species were subjected  to air drying under sheltered condition  (under roof) and drying in a dehumidifying chamber.  At the end of each test.  the defect of each specimen  was recorded, and the most appropriate form of relation between duration  of drying and moisture  content  decrease was sought.From data analysis it was shown that a power form of relationship (Y = aXb) was reasonable, with coefficient  of correlation values varying between  0.80-0.90.The result also shows  that the longest air drying time (from 60% to 20%  moisture  content)  was recorded by kayu besi (53 days) and the shortest  by dama-dama  and palapi  (18 days).As  has been anticipated,  drying  in the dehumidifier   has reduced  considerably  the time  required for  drying from 60% to 20% moisture content. For example for the three species mentioned  above  the figures  were 20 days for  kayu  besi and 5 days for  dama-dama  and palapi.The result shows further  that severe defect was observed in kolaka,  bugis, suling and belu itam.  The remaining species have either moderate or slight defect.

Abstract

This paper deals with the study of the influence of active alkali concentration to the properties of coconut trunk (cocos nucifera L.) sulphate pulping trials were conducted in laboratory digester with the cooking liquor circulation, using three levels of active alkali, i,e 14, 16 and 18% cooking sulfidity was 25%, wood to liquor ratio was 1:4, and maximum temperature was 165°c maintained for 120 minutes.Pulp yields from coconut trunks are ranged from 39.9 to 40.9% with permanganate number of 8.17 to 11.15. the increasing amount of active alkali has no significant influence to the yield, and overall physical properties of the pulp but tear factor. The higher active alkali concentration, the lower permanganate number and the higher alkali consumption. It is hope that the sulphate pulping of coconut trunk with active alkali of 16% would give adequate yield and processing properties.

Abstract

An investigation on lac cultivation was carried out in Probolinggo Forest District in September 1988. The purpose is to find possible ways of increasing the production. Host trees and methods for lac cultivation were observed. The results reveal that: Kesambi trees are good as the host for lac cultivation because they have sap density of 0.16 and sap reaction of 0.59 which which condition is favorable for lac survivals.Higher lac production can be obtained by using host trees that have many branches and twigs. Therefore, host trees need to be pruned in order to provide many new branches and twigs.Lacquor secretion yield can be harvested 5 months after lac cultivation. The lacquor production, thew is sorted intolacquor for cultivation and industrial materials. The cultivated lac can produce lacquor to the amount of three to five fold, depending on the quality of lac cu1tivated and the existance of diseases.

Abstract

Tujuan penelitian ini adalah mengetahui pengaruh sifat fisik dan anatorni terhadap sifat pengeringan enam jenis kayu, yaitu tisuk (Hibisms 111acropf?yllus), gading (Koilodepas sp), mahang (Macarangaf?ypoleuca), telisai (Planchoniagrandis), sibau (Bl11meodendronkurzi1), clankenari (Santiria laevigata). Sifat fisik meliputi berat jenis dan penyusutan; sedangkan sifat anatomi kayu adalah lebar jari-jari. Sedangkan sifat pengeringan yang diuji meliputi cacat pecah ujung dan permukaan serta pecah di bagian dalam kayu, menggunakan metode pengeringan suhu tinggi (100°C). Berdasarkan kelas kerusakan/cacat yang terjadi dari hasil pengeringan suhu tinggi, kemudian ditetapkan sifat pengeringan untuk masing-masing jenis kayu. Hasil penelitian menunjukkan bahwa terdapat hubungan regresi geometrik antara BJ dengan penyusutan tangensial (R' = 0,78), dan regresi linier antara lebar jari-jari dengan sifat pengeringan kayu (R' = 0,60). Kayu tisuk dan sibau termasuk kayu yang sangat mudah dikeringkan karena memiliki berat jenis rendah sampai sedang, dan diameter pembuluh yang cukup besar. Kayu mahang, gading dan telisai sangat sulit dikeringkan. Faktor penyebab, di antaranya adalah berat jenis kayu yang terlalu tinggi (gading dan telisai) dan terlalu rendah (mahang), serta struktur anatomi yang tidak mendukung yaitu dinding serat yang tebal (kayu gading), diameter pembuluh kecil (mahang dan gading), dan berisi tilosis (gading dan telisai).

Abstract

Taungya farming system  has given peasants an opportunity to produce some food  without  getting  involved in forest planting  activities. It is not only  cheap, but also very  attractive to peoples around the  forest. This report was a result of data processing of  peasant's income  in  taungya   farming  system in Bojonegoro Forest District, East Java,   early in 1986.The total peasant's income consists of taungya farming income, other forest  activities  income,  and  income  of  non forest   activities.  Generaly,  the share of each  type  of income    to the average total  peasant's income per year is concecutively 36.8 % (Rp 57,381) of  taungya  farming income;  26.9 % (Rp 41,976) of  other  forest  activities  income  and  36.3.   % (Rp 56,473)  of  non  forest  activities  income.The proportion of  taungya  income to  total  income  of  lnmas peasants (55.8%) is higher  than  Non-Inmas  peasants (21.8%); whereas  peasants working on a low site  quality    have proportion of taungya income to total income, 12.3%, which is lower than those  working  on a  site  with  higher  quality (50.1%).In fact, peasant's income that resultfrom forest activities, especially taungya   farming  still  could  not  cope  withtheir  poverty.   Average   total  income   of  peasants is  Rp  50,814 per capita  in  a year or only 77 % of  the minimum living standard  cost  only.   Nevertheless,  the  average   total  income   of  peasants  had good  distribution,   as far as it is concerned  this would  not  cause an alarming  trouble   to  the  social   community.

Abstract

Jenis kayu yang digunakan di lndustri kayu lapis di Indonesia pada umumnya mempunyai kelas awet rendah. Oleh karena itu untuk meningkatkan keawetan kayu lapis tersebut perlu dilakukan usaha pengawetan. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh bahan pengawet permetrin terhadap keteguhan rekat dan keawetan kayu lapis tusam yang direkat dengan fenol formaldehida. Kandungan bahan aktif permetrin dalam larutun bahan pengawet yang digunakan adalah 36,8 % dan konsentrasi bahan pengawet yang ditambahkannke dalam perekat fenol formardehida adalah 0.0. 0.25, 0.50, 0. 75, 1.0, 1.25, 1.50, 1. 75 dan 2.0% dari berat perekat.Hasil penelitian menunjukkan bahwa penambahan bahan pengawet permetrin dalam perekat fenol formaldehida pada pembuatan kayu lapis tusam tidak berpengaruh terhadap keteguhan rekat kayu lapis tusam baik yang diuji menurut standar Indonesia maupun standar Jepang. Sebaliknya penambahan bahan pengawet permetrin tersebut berpengaruh pada keawetan kayu                                                                                                                                                                                        235 lapis tusam terhadap serangan rayap tanah dan rayap kayu kering. Kematian rayap.tanah dan rayap kayu kering meningkat dengan meningkatnya konsentrasi permetrin. Kehilangan berat dan derajat serangan menurun dengan meningkatnya konsentrasi permetrin. Penambahan bahan pengawet permetrin sebanyak 2 % dari berat perekat fenol formadehida dapat menahan serangan rayap tanah maupun rayap kayu kering. Keteguhan rekat kayu lapis tusam yang dibuat dengan berbagai konsentrasi permetrin semuanya memenuhi standar Indonesia dan standar Jepang.
