Abstract

Various sawmilling industries of high, medium and small enterprises operate in Indonesia. During log conversion into sawn timber, wood waste occurs in the form of left over cut and sawdust. Small cut waste is lignocellulose material which is potentially used for bioethanol production. This paper studies the possibility of bioethanol production from sengon sawmill waste. High loading substrate method was applied by hydrolyzing high concentration substrate, i.e 15, 25 and 35% and two concentrations of enzymes (12.5 and 15 FPU/g substrate). Result showed that the treatment of 25% substrate concentration and 15 FPU/g cellulase substrate produced the highest reducing sugar of 248.3 mg/mL, while the substrate concentration of 35% generated the highest ethanol content i.e 17.7% and recovery about 38.4%. It can be concluded that the high loading substrate method could increase the ethanol concentration made from sengon wood waste.

Abstract

Currently, Ganoderma lucidum, Pleurotus ostreatus, and P. sajor-caju are prospective fungi for decomposition of pulp and paper industry’s waste. This paper studies the possible utilization of rotting fungi spent compost for decomposition of mangium sludge. Initially, the fungi were cultivated for three months on medium prepared from sengon (Falcataria moluccana) wood sawdust. The rotting fungi spent compost was then used for degrader activator by inoculating them into the Acacia mangium sludge, then, incubated for six months. Results revealed that after three month incubation the values of the Biological Conversion Efficiency (BCE) of sengon reached 13.41% (G. lucidum), 47.11% (P. ostreatus), and 38.06% (P. sajor-caju). Fungal inoculation into the sludge improved the C/N ratio as much as 71.59%. The usage of higher concentration of G. lucidum inoculums increased the C/N ratio value. After six months incubation, some sludge contents reduced by 48.76% (N), 35.42% (P) and 25% (K), except for Ca and Mg, which increased by 112.9% and 6.67%, respectively. Mineral content of the untreated sludge decreased by about 66.12% (Ca), 68.75% (P) and 4.17% (Mg), except for K and Ca which were increased by 2.08% and 64.52%, respectively. Cation exchange capacity (CEC) value of the sludge after incubation increased by about 3.85% (control) and 56.8% (treated).

Abstract

Jabon (Anthocephalus cadamba Miq.) has been widely planted by communities as an alternative of building and furniture materials. However, there are two inferior jabon wood proferties i.e. low strength (Class IV) and less durable (Class V). Jabon-Bamboo Laminated Board (JBLB) is one posible product that may be developed to improve jabon’s wood properties. This study investigates quality improvement of jabon boards due to fabrication as JBLB and the effect of bamboo layers number on JBLB properties. Andong bamboo (Gigantochloa pseudoarundinaceae (Steudel) Widjaja) and mayan bamboo (Gigantochloa robusta Kurz) were used in this study. Initially, jabon boards and 3 bamboo strips were preserved by soaking in 7% boron solution until reaching the targeted retention of 6 kg/m . The JBLB were manufactured in four different layer compositions using Isocyanate adhesive. The glue spread and cold pressing time 2 applied were 250 g/m and one hour, respectively. Results showed that quality of JBLB was significantly affected by the number of bamboo layers, except bonding strength. Bamboo lamination on jabon board has increased the product density by 10%, modulus of elasticity (MOE) by 71%, modulus of rupture (MOR) by 34% and compression strength by 20% compared with the initial jabon properties. Strength values of JBLB are classified into wood strength class-III .

Abstract

One indicator of sustainable forest management is the minimum impact of residual stand damage caused by timber harvesting activities. This paper examines stand damage due to timber harvesting on hilly tropical forest, Central Kalimantan. The study was carried out using samples plot of 200 m x 100 m that was systematically placed on three selected cutting plots with different chainsaw operators working experience. Results showed that the degree of residual stands damage due to timber harvesting ranged between 19.37 – 34.9% with an average of 24.37% categorized as light stand damage. The average stands damage due to felling was 16.27% and skidding was 8.1%. Unexperienced chainsaw operators tend to cause greater damage than well trained chainsaw. Type of residual damage due to the felling on either sloping, rather steep or steep terrain was dominated by broken tree trunks. The most common type of residual stand damage due to skidding was the collapsed or tilted trees. The residual stand damage due to timber harvesting could be reduced by imposing intensive supervision in the felling sites and provide training and/or refresher to chainsaw and skidding tractor operators especially on cutting technique and environmentally friendly skidding.

Abstract

Natural durability of each bamboo species is different, thus information on natural durability of bamboo species is important for its utilization. This paper investigates the natural resistance of bamboo species against subterranean termites as a basis for species classification. Twenty species of bamboo from various regions in Indonesia (West Java, Banten, the Central of Java, Lampung and Bogor Botanical Garden) were tested against subterranean termites Coptotermes curvignathus Holmgren according to SNI 7204-2014. Parameters observed were weight loss percentage of bamboo, survival rate of the termites and degree of attack (subjectively). Results showed that based on the weight loss, three bamboo species could be grouped into resistance class I, five species into class II, three species into class III, seven species as class IV and two species as class V. Based on the survival rate of the termites, one of the bamboo species was classified in class I, four species in class II, one species in class III, 11 species in class IV, and three species in class V. Furthermore, according to the degree of attack, four species were heavily damaged, while 16 species showed moderately damage. From the result, it can be concluded that one species of bamboo namely apus (Gigantochloa apus) has the highest resistance class (class I), and four other species of bamboo namely hitam (G. atroviolacea), kuring (G. kuring), india/tulda (Bambusa tulda) and lemang (Schizostachyum brachycladum), were classified in resistance class II. In the utlization, the five species of bamboo can be used without preservation, while the remaining 15 species of bamboo in resistance class III V should be preserved before using.

Abstract

Malapari (Pongamia pinnata (L.) Pierre) is one of the most potential biodiesel raw materials to be developed in Indonesia. The plant is natura ly distributed from Sumatera to Papua. However, oil content and its physico-chemical properties of malapari originated from Java was limitedly known. This study investigates chemical composition of malapari seeds, identifies fatty acid composition of the produced seed oil and characterises physico-chemical properties of malapari oil. Composition of chemical content of malapari seeds was analyzed through proximate analysis. Physico-chemical properties of malapari oil were analyzed using the ASTM test method. Results showed that Batukaras population is the best population to be used as biodiesel raw material source because it has the highest value of oil content. Besides, the Batukaras population has the lowest specific gravity, viscosity and acid value. Malapari oil is dominated by oleic and linoleic fatty acids which are potentia ly unsaturated fatty acids for biodiesel. Value of fatty acids (oleic and linoleic) and physico chemical properties (specific gravity and calorific value) of pongamia crude oils suggested that the five populations have been eligible for biodiesel feedstock.
