Oyster mushroom (Pleurotus ostreatus) was cultivated on logs of five wood species, i.e. hamerang (Ficus grossularoides Burn.f.), jeungjing (Albizia falcataria (L.) Eosb.), jirak (Symplocos fasciculata Zoll.), kihuut (Vernonia arborea Ham.) and manii (Maesopsis eminii Engl.).The logs were kept in a house, at Gunung Bunder Forest Complex, Bogor (first experiment) and under soka trees in Bogor (second experiment).The logs start producing fungus two months after inoculation. After eight month observation, the highest yield per log was obtained from manii 1139.90 g (in a house) and 1171.62 g (under soka trees; and the lowest yield was on jirak (0.99 g). Total yield during the experiment per m of log, under soka trees was higher than that cultivated in a house Manii and hamerang logs probably belong to media for oyster mushroom than other species

Oyster mushroom was cultivated on sawdust media of damar (Agathis sp), durian (Durio zibethinus Murr.), teak. (Tectona grandis L.f), jeungjing (Albizia falcataria (L.) Fosb.), rubber (Hevea brasiliensis Muell. Arg.), coconut (Cocos nucifera L.), kemang (Mangifera caesia Jack), manii (Maesopsis eminii Engl.), meranti merah (Shorea johorensis Foxw.), nangka (Artocarpus integra Merr.), pulai (Alstonia scholaris R.Br.), sehiye (Sterculia macrophylla Vent.), shiega (Celtis latifolia Planch.), sihara (Ganophyllum falcatum BL.) and pine (Pinus merkusii Jung et De Vr.). The composition of the media was 77,5 % sawdust mixed with 20 % rice bran, 0,5 % lime, 0,5 % trisuperhosphate and 1,5 % gypsum. Each media was mixed with distilled water 125 - 150 % per dry weight of media. The media was cooled after autoclave sterilization before being inoculated with pure culture of the mushroom. The mature mushroom was harvested daily after the growth of the fruiting body. Biological Efficiency (BE) was calculated based on the yield of fresh mushroom in proportion with the dry weight of material used as media.The higher BE was obtained from rubber wood sawdust media (86.15 %), nangka (66.26 %), kemang (63,85%) and pulai (63.52). The lowest BE was obtained from damar (28.22 %).

The result of a study on the susceptibility of rattan to fungal attack. Three rattan species i.e. irit (Calamus trachy- coleus Becc.), manau (C. manan Miq.) and semambu (C. scipionum Lour.) both peeled and unpeeled were kept out door. Fungal infestation was than observed after one, two, four and eight week periods. At the end of experiment, each rattan sample was split into two halves to observe internal discoloration. The result showes that irit was most susceptible to stain attack and infestation on peeled cane seems to be more severe compared with unpeeled ones. The average rate of infes- tation of the rattan species studied was 10.59 % (4.65 - 14,92 %) per week. The lowest and highest rate of infestation were shown respectively by unpeeled manau and peeled irit rattan. It was also revealed that 93.33 % of the test speciments were internally stained, of which 46.67 % were badly stained. Semambu rattan seems to beresistant to fungal infestation, most of which showing low degree of internal stain.

Wood still performs as the main materials for railway sleepers, especially at their connected portions, cross and bridge. So far, wood has not yet been effectively substituded by other materials. However, wood based railway sleepers are susceptible to deterioration by the decaying fungi. This study examined, the decay resistance of three wood species i.e. bangkirai (Shorea laevis), meranti batu (Shorea platyclados) and rasamala (Altingia exelsa). Samples were evaluated against the decayingfungi in a laboratory experiment using DIN 52176-modified standard.Results indicated that bangkirai and meranti batu were classified resistance against fungalattacks (Class II), whereas, rasamala was categorized moderately resistant (Class III). The weight loss percentage of rasamala was higher than those of bangkirai and meranti batu. The ability of fungus to degrade certain wood was depended upon kinds of wood and fungus itself. Fungi with significant decay ability were Pycnoporus sanguineus HHB-324, Schizophyllum commune, Polyporus sp., Trametes sp. and Tyromyces palustris.The highest weight losses were recorded on samples exposed consecutively to Pycnoporussanguineus and Schizophyllum commune.

Wood waste such as sawdust, leaves of legume plants such as turi (Sesbania grandiflora Pers.) and lamtoro gung (Leucaena leucocephala (Lam.) de Wit.) were used as substrates for oyster mushroom, Pleurotus ostreatus cultivation. The substrate consisted of rubber wood sawdust (Hevea brasiliensis Muell. Arg.) mixed with turi or lamtoro gung leaves containing 50%, 100%, 150%, 200%, by weight and distilled water. The substrate was allowed to cool after autoclave sterilization before being inoculated with pure culture oyster mushroom.The mushroom was harvested every day after the growth of the fruiting body. The average yield of the entire treatments was 643.00 g (532. 29- 744. 69 g) per kg of dry weight of substrate. The highest product was obtained from rubber wood sawdust substrate mixed with 10% turi leaf.

Dalam upaya meningkatkan pemanfaatan dan efisiensi pengolahan limbah kayu untuk pulp, telah dilakukan studi biodelignifikasi limbah kayu oleh jamur pelapuk putih. Penelitian meliputi perbanyakan isolat, inokulasi dan inkubasi jamur pelapuk putih pada campuran limbah kayu pembalakan, sedangkan di lapangan dilakukan koleksi, isolasi dan seleksi jamur pelapuk lignin dari Kalimantan Timur.Pada penelitian ini digunakan empat jenis jamur pelapuk putih yaitu isolat Acasia. Isolat Mahang, isolat Super-fungi dan isolat Phanaerochaete chrysosporium. Ke empat jenis jamur ini diinokulasikan kepada dua belas jenis limbah kayu pembalakan, antara lain : nyatoh (Palaquium sp), bengkal (Albizia procera Benth), macaranga (Macaranga sp), simpur (Dillenia sp), Bangkirai (Shorea laevifolia Endert), medang (Litsea firma Hook), meranti merah (Shore selanica BL), kayu arang (Diospyros pilosanthera Blanco). kayu bawang (Scorodocarpus bomeensis Becc), pare-pare (Glochidion sp), meranti putih (Shorea sp) dan maringkau (Xylopia sp).Tujuan penelitian adalah untuk menentukan isolat jamur yang efektif mendelignifikasi kayu, serta mengetahui pengaruh waktu inkubasi dan jumlah inokulum terhadap kandungan komponen kimia kayu.Hasil penelitian menunjukkan bahwa aplikasi jamur pelapuk putih terutama isolat Acasia sangat efektif menurunkan kadar lignin. lsolat Acasia merupakan jamur terbaik dari empat jenis jamur yang diseleksi, karena mampu mendegradasi lignin dan komponen kimia lainnya seperti holoselulosa dan kadar sari.Perlakuan pendahuluan delignifikasi campuran limbah kayu pembalakan dengan waktu inkubasi 30 hari dan jumlah isolat 5%, efektif menurunkan lignin. lsolat jamur hasil isolasi dari Kalimantan Timur sebagian besar merupakan jamur pelapuk lignin.

The media used in the experiment were sawdust of eight wood species mixed with 1% calcium carbonate (CaC03), 1% gypsum, 0.5% fertilizers i.e. urea, ammonium sulphate (ZA), KCL, NPK and trisuperphosphate (TSP) and distilled water, respectively. The substrate was cooled after autoclave sterilization before being inoculated with pure culture of oyster mushroom. The mature mushrooms were harvested daily after the growth of fruiting body.The media started producing mushroom two months after inoculation (28 - 45 days). The highest yield was obtained from rubberwood sawdust mixed with ZA (362.43 g) and the lowest yield was on teak sawdust containing urea (90.14 g) per 500 grams media. Media from rubberwood, weru, jeungjing and pulai sawdust were suitable for mushroom culture. Fertilizer supplement seems to improve mushroom yield. ZA, urea were more effective than KCL fertilizer for mushroom production.The average Biological Efficiency (BE) of entire treatments was 84.32% (35.25-140.23%). The relatively high BE was obtained from weru, rubber and jeungjing and the lowest BE was on teak sawdust media.

Ear mushroom (Auricularia polytrica) was cultivated on turi logs. The logs were kept slanted on an angle of ± 60° with bamboo supports before being inoculated with spawn of ear mushroom at Bogor. The mature mushroom were harvested daily after the growth of the fruiting body.The logs start producing mushroom two months after inoculation. After seven month of observation, the average total yield per log was 0.589 kg (at the base of trunk), 0.885 kg (middle of trunk), 0.648 kg (top of trunk) and 0.141 kg (branch).The total yield during seven month observation was obtained from the base of trunk (61.864 kg), middle of trunk (179.120 kg), top of trunk (203.656 kg) and branch (74.778 kg) per m3 of log.
