Abstract

Penelitian ini bertujuan untuk menguji kualitas papan gergajian manglid (Manglieta glauca Bl.) dari dua pola penggergajian berdasarkan karakteristik cacat bentuk dan cacat terpisahnya serat. Sampel yang digunakan adalah log manglid yang berasal dari hutan rakyat Desa Sodonghilir, Kecamatan Sodonghilir, Kabupaten Tasikmalaya. Sejumlah 35 papan gergajian dari masing-masing pola penggergajian satu sisi dan pola penggergajian semi perempatan diambil sebagai contoh uji pengamatan. Hasil penelitian menunjukkan bahwa jenis cacat bentuk yang terjadi pada papan gergajian manglid dari kedua pola penggergajian adalah cacat memuntir (55,91 %), cacat melengkung (53,57 %) dan cacat membusur (41,35 %). Sedangkan jenis cacat terpisahnya serat yang terjadi adalah cacat pecah tertutup (18,25 %), pecah terbuka (14,13 %) dan belah (2,82 %). Perbedaan nyata antara papan dari kedua pola penggergajian terjadi pada jenis cacat membusur dan memuntir. Sementara pada jenis cacat melengkung, pecah tertutup, pecah terbuka, dan belah relatif seragam antara dua pola penggergajian. Papan dari pola penggergajian satu sisi memiliki cacat membusur dan persentase gubal yang lebih kecil dari pola semi perempatan, tetapi memiliki cacat melengkung yang lebih besar. Berdasarkan kriteria cacat bentuk dan terpisahnya serat, papan dari pola satu sisi memiliki kualitas lebih baik serta lebih banyak yang memenuhi standarmutu berdasarkan Standar Nasional Indonesia.

Abstract

Investigation about the cold-soaking treatment has been conducted on five wood species (i.e. keruing, nyatoh, melur, pulai and meranti merah) for housing purposes. The penetrating preservative for this case was CCB (copper-chrome-boron) chemicals. Before being treated. the wood specimens measuring 3 - 5 cm (in length) by 3 - 5 cm (in width) were prepared from each of the five species. Such specimens could not be treated by implementing the conventionally prescribed treating schedule. because the measurement of preservative retention at such schedule should follow the revised standard/schedule which differed from the conventional one. Hence, in cold-soaking treatment using CCB preservative, the specimens of wood species for such purpose had to be modified in their sizes/shapes.Three different sizes/shapes were prepared, i.e. beam, truss, and rafters; and then were allowed to reach their air-dry moisture contents. Afterwards. they underwent cold-soaking treatment using CCB preservative in two different concentrations (i.e. 5 percent and 10 percent). Meanwhile. the soaking durations implemented for each concentration were consecutively 3,5 and 7 days.The results revealed that all the wood species in all three sizes/shapes (i.e. beam. truss. and rafters)could be treated using the revised schedule. Except for meranti in truss and rafter. Related as such. the revised treating schedule for these five species has been appropriately devised.

Abstract

Perlakuan panas merupakan salah satu metode yang dapat meningkatkan kualitas kayu termasuk untuk kayu cepat tumbuh. Namun perlakuan tersebut dapat menyebabkan cacat pengeringan serta perubahan sifat pemesinan setelah perlakuan panas. Tujuan penelitian ini untuk mengevaluasi pengaruh variasi jenis kayu dan waktu pemanasan terhadap adanya cacat pengeringan dan pemesinan kayu cepat tumbuh. Jenis kayu cepat tumbuh yang digunakan adalah jati, mangium, jabon dan sengon. Perlakuan panas dilakukan pada suhu 165ºC dengan variasi waktu 0 jam (kontrol), 2 jam dan 6 jam. Hasil penelitian menunjukkan bahwa kadar air dan kerapatan kayu menurun setelah perlakuan panas. Perlakuan panas berhasil menurunkan kadar air 57% dan menyebabkan penurunan kerapatan kayu hingga 20% dibandingkan dengan kayu kontrolnya. Cacat pengeringan retak ujung pada jati, mangium, jabon dan sengon meningkat setelah perlakuan panas selama 2 dan 6 jam. Di sisi lain, cacat retak permukaan pada jati, mangium, sengon dan jabon berkurang. Cacat setelah menerapkan kegiatan pemesinan yaitu cacat pengamplasan, penyerutan, pembentukan, dan pengeboran menurun pada jati, mangium, jabon dan sengon setelah perlakuan panas 2 dan 6 jam. Jati adalah spesies kayu terbaik dalam hal kualitas pemesinan setelah perlakuan panas diikuti oleh jabon, mangium, dan sengon. Pada suhu 165°C dalam 2 jam dianggap sebagai waktu yang tepat untuk perlakuan panas dalam hal memperoleh cacat minimal pengeringan dan pemesinan.

Abstract

Transmigration-based Timber Estate (TTE) is an effort to combine transmigration programme and Timber Estate development, and it involves many institutions which sometimes have conflicting interests. The objective of this study is to identify existing institution, efficiency and effectiveness of TTE programme and to study the socio-economic condition of transmigrant.The result of analysis shows that community around forest adhered to traditional institution. And their understanding on the prevailing external institution of government and timber estate concession were relatively low. The aspiration of local community for having plantation usually ended up in chopping activity. Average chopped area was 13 Ha per household. This practice supported by village officials and made this institutional problem more complicated. Their claim of forest area as a customary right was triggered by their insecurity of a continous access to forest as a source of their livelihood.Only about 21,5% local community were willing to be relocated as a local transmigrant and only about 25-30% of those were worked effectively for timber estate, so TTE programme is yet considered effective in relocating, modifying way of life and improving participation of local community. The proprietary right on agricultural land in TTE programme was only 0,25Ha, so giving proprietary right on agricultural land in adequate extent is highly recommended.There were three kind of activities in timber estate development, namely land preparation,nursery, planting and weeding. Wage payment system on land preparation activity was contractual wages at about Rp 85.000-115.000 per Ha. The wage of nursery, planting and weeding activities were about Rp 4. 250- 4. 750 per day. Compared to the Regional Minimum Wages (UMR) for this region in 1993 which was Rp 4.150, labor wage of timber estate development met its social function. Average income labor family per month in land preparation was Rp 253. 600, whereas for planting and weeding was Rp 173. 100 and which nursery activity was Rp 163. 100. Compared to the Minimum Physical Needs (KFM) for this region which was Rp 266.197 in 1993, the earning of labor family from TTE was lower. It means their living condition had not improved yet.

Abstract

Resin fenol formaldehida merupakan suatu perekat yang digunakan dalam pembuatan kayu lapis eksterior. Beberapa bahan dapat ditambahkan pada resin tersebut untuk menghemat biaya. Pada tulisan ini dikemukakan hasil penelitian tentang pengaruh penambahan ekstender pada resin fenol formaldehida terhadap keteguhan rekat kayu lapis tusam (Pinus merkusii Jungh et. de Vrise). Ekstender yang digunakan ada 2 macam, yaitu tepung gandum dan tepung gaplek dengan 5 macam kadar yaitu 0%, 5%, 10%, 15% dan 20% dari berat perekat cair.Hasil penelitian menunjukkan bahwa macam ekstender tidak berpengaruh nyata terhadap keteguhan rekat kayu lapis, sedangkan kadar ekstender berpengaruh sangat nyata. Semakin tinggi kadar ekstender, keteguhan rekat kayu lapis cenderung berkurang. Kadar ekstender maksimum yang memenuhi persyaratan Standar Indonesia adalah 20% masing-masing untuk tepung terigu dan tepung gaplek, sedangkan pada Standar Inggris adalah 20% untuk tepung terigu dan 10% tepung gaplek.

Abstract

The objective of the study was to determine the effect of various layer compositions on the properties of 3-layer vertically glued laminated bamboo beam (LBB). Bamboo strips for LBB fabrication were prepared from mature culms (± 4 years old) of andong bamboo (Gigantochloa pseudoarundinacea (Steud.) Widjaja) collected from private gardens in West Java. The strips were pre-treated by soaking them in 7% boron solution for four hours. Three-layer LBBs were manufactured with six different layer compositions, including bamboo combination with wood planks of manii (Maesopsis eminii Engl.) or sengon (Falcataria moluccana (Miq.) Barneby & J.W. Grimes) as the core layer. The LBB was manufactured using Water Based Polymer-Isocyanate (WBPI) adhesive. The glue spread and cold pressing time applied were 250 g/m2  and one hour, respectively. Results showed that the average density, moisture content, thickness swelling, and width expansion of LBB were 0.65 g/cm3; 11.1%; 2.09%; and 1.99%, respectively. No delamination occurred in all samples using WBPI adhesive, which indicates high bonding quality. The average bonding strength and percentage bamboo failure (dry test) of  LBB were 61.6 kg/cm2  and 90%, respectively. The physical and mechanical properties of LBB were significantly affected by the layer composition. The presence of wood laminates as the core layer of LBB and the cross wide orientation of the core layer decreased mechanical properties of LBB. On the contrary, the presence of cross-layer in LBB structure increased dimensional stability of the produced LBB.Three-layer thick laminated bamboo beam made of vertically glued andong bamboo strips with various constituted layer  composition and  all constitued layers laminated together in parallel grain direction had strength values comparable to those of class II of solid wood strength, eventhough the core layer was made of sengon or manii planks.

Abstract

An investigation on various aspects of timber harvesting practicues in two loggini companies in Riau has been  conducud in June 1991. One of them is operating in dry  land forests  and the other is in swamp forests.Road construction in the first  company is accomplished by the steps of selecting route Iocation, land clearing and road forming, road grading, and right of way clearing with the total cost of Rp. 3.8 million/km. Whereas, log extraction is done by the steps of felling, skidding, debarking, loading, hauling and unloading with the total cost of Rp. 8,210/cu.m.In swamp forests,  rail  road construction follows the steps of route survey, right of way clearing, installing rall suppors and steel rails with the cost of Rp. 8,420,000/km, including the costs of logs used for the supports amountr to 151  cu.m/km and steel rails. By using this facility and manual (kuda-kuda) skidding, it is found that the cost of log extraction  is Rp. 13,250/cu.m.Logging roads have many land openings and steep, bare soils so that they are in the condition of high soil erosion potential. Whereas, for rail roads, it is noticed that their soil erosion is low because the land on both sides and under  the rails is well covered by litter,  logs  and vegelation roots.

Abstract

Piperonal as a precursor of cancer drug (Curcumin analogues) can be synthesized from extract of lawang’s bark (Cinnamomum culilawan Blume) with multiple stages, among others: isolation of  essential oils, isolation safrole, safrole isomerization, and synthesis of piperonal. Essential oils were isolated from the bark of lawang (the water content of 46.2%) using a water distillation system with 1/3 volume of high boiler for five hours. Isolation of safrole from lawang bark oils was performed using NaOH solution and purified using reduced pressure distillation system at a temperature of 90-123°C / 1 mmHg. The safrole isomerization was undergone using alkali catalyst (KOH) without solvent at a temperature of 120°C for 8 hours. Oxidation of isosafrol was performed using KMnO4 in acidic conditions using a KTF tween 80 at a temperature below 30°C, and purified using silica gel. Results of isolation yield 0.94% with 14 components were determined through GC-MS, including 67.35% eugenol, safrole 13.96%, 12.61% methyl eugenol, 4-terpineol sineol 1.79% and 1.55%. The isolated safrole yield of 17.21% with purity testing and identification using FTIR, 1H- NMR and GCMS confirmed the product was safrole. The isomerization obtained yield of 77.56% with GC analysis indicated compounds of  cis-isosafrole and trans-isosafrole. The results of  oxidation obtained yield of  65.63% with a purity of 100% by GCMS and the 1H-NMR indicated the product is piperonal.
